Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention is mainly applied to concrete snow drifts, agricultural irrigation canals, drains, and the like, but is not limited to these, and metal products such as The present invention relates to a lubricating covering material attached to a snow removal plate or a roof of a house.

[Conventional technology]

Concrete snow gutters have been built in the urban area of the snowfall area, and snow accumulated on roads has been poured to remove snow.However, when the amount of flowing water is low or the slope is low, the effect of snowfall decreases, Due to the snow, the inside of the ditch was blocked like a weir, and there was a problem that overflowed water could damage houses and roads. As one means for solving this, a measure has been proposed in which the inside of the groove is not closed because the inside of the groove is reduced by applying a paint to the inside of a concrete snow drift to finish the surface as a slippery surface and lowering the friction coefficient.

The problem here is paint. It has been proven that in order to increase the durability and corrosion resistance of the coating film, it is proportional to the thickness of the coating film, so that a thick coating film can be obtained, and furthermore, a smooth surface can be obtained without dripping during coating. It is necessary to have a paint that can be finished and has excellent abrasion resistance and impact resistance. Corresponding paints have been developed in recent years, and as a result of being applied to existing snow drifts made of concrete, the injected snow does not adhere to the snow drifts, reducing the amount of flowing water even at low gradients. However, the result of flowing down very well without stagnation was obtained.

The paint is a two-pack paint composed of a paint liquid containing a polyurethane resin as a main component containing no solvent and a curing agent made of a modified isocyanate resin (manufactured and sold by Mitsui Kinzoku Paint Chemical Co., Ltd. under the trade name "Mizeron"). ). This paint can be applied not only to concrete but also to iron, aluminum, wood, synthetic resin, etc.
3 If there is no pinholes, blisters or craters, it can be applied to a thickness of 500μ to several cm at a time by brush coating, flow coating or spray coating with a special coating machine. It is excellent in chemical resistance and weather resistance.

[Problems to be solved by the invention]

When applying the solventless two-component paint to an existing concrete snow gutter, in particular, a base treatment, an undercoat, an overcoat,
This is due to each of the repairing steps, and it is necessary to remove the water by cleaning the coated surface to form a rough surface and drying it during the base treatment. This moisture removal may be performed by forced drying with hot air, but it depends on the weather, so it is necessary to select a construction day other than a rainy day or a snowfall day, and in a place where spring water etc. It is necessary to carry out work to prevent such conditions, and it is limited to the time when favorable conditions are met at the time of construction.Especially in the snowfall area, there are few days when favorable conditions can be obtained, and even in favorable conditions due to weather, Therefore, there are few cases where artificial conditions such as a constructor are prepared, and thus it is necessary to satisfy limited conditions at the time of construction. In addition, this type of construction is often public and almost impossible to construct depending on the timing of ordering the construction.

Accordingly, the solvent-free two-pack paint is applied to a surface such as a snow drift where a lubricated surface is required, so that the surface can be immediately applied without being influenced by weather, topography, or artificially. It has been proposed to provide a lubricating surface by means of applying a coating material using a. Based on the proposal, coating materials of various forms using solventless two-component paints were trial-produced, but the drawback of this paint was that when the formed coating material was bent to a right angle or more acute angles, it was refracted. Cracks were generated in the part that was cracked.

From the above problems, the present invention can be easily manufactured without cracking by repeating research and experiment, and can be attached to a structure such as a snow drift by a simple operation. An object of the present invention is to provide a lubricating coating material.

[Means for solving the problem]

In order to solve the above-mentioned problem, a net is used as a core material, and a thick film layer in which a solvent-free paint is attached to both front and back surfaces of the core material is provided in a state of being integrally connected through a mesh.

[Action]

Therefore, the lubricating coating material of the present invention may be attached to a necessary surface of a lubricating surface such as a building or a vessel by an appropriate means, and it is necessary to perform a pretreatment such as cleaning on the surface to be adhered at that time. And can be directly attached.

[Examples] As specifically shown in the drawing, the lubricating coating material according to the present invention is made of a metal or a synthetic resin net such as nylon. Thick film layers 2, 2 made of a solventless two-liquid paint are adhered in a state of being integrally connected to each other through a mesh.

The solvent-free two-pack paint is specifically manufactured and sold by Mitsui Kinzoku Paint Chemical Co., Ltd.
The composition component of the coating liquid is a polyol resin
It consists of 40-60%, color pigment 30-40%, extender pigment 2-10%, and additive 5-15%. The composition of the curing agent is 100% of the modified isocyanate resin. 2: 1
This paint was blended at a ratio of ~ 4: 1, and this paint was applied to both front and back surfaces of a core material 1 made of a net by brush application to form a thick film layer 2,
2 may be attached, but in order to enable mass production, the core material 1 formed in a belt shape is degreased and dried, and then sent in a belt shape. During the traveling, the paint is extruded from above into a belt shape. The thick film tanks 2, 2 are attached to both front and back surfaces at once by being inserted through a pair of upper and lower rollers that rotate
Are attached to each other through the mesh of the core material 1 while being connected together, and applied to a thick film (one side approximately 0.5 to 3 mm), and the surface is formed into a product with a smooth surface close to a mirror surface regardless of the unevenness of the mesh Is what is done.

When the lubricating coating material having the above-mentioned structure is attached to the inner surface of the snow drift 3 made of concrete, for example, as shown in FIG. Is applied along the inner surface of the snow flow groove 3, and both sides of the lubricating covering material are bent so as to cover the upper surface of the snow flow groove 3, and the bent portion is attached to a nail 4 driving means or the snow flow groove 3. By fixing to the provided anchor by means of screwing or the like, the inner surface of the snow drift 3 can be finished to a smooth surface at once.

In addition, when the lubricating covering material having the above-mentioned structure is laid on the roof, it is roofed like a tiled roof. And cover the connection with a cap or thick film layer 2
It is only necessary to apply the same paint as described above and seal it.

〔The invention's effect〕

The lubricating coating material according to the present invention is obtained by attaching a thick film layer made of a solvent-free paint to the front and back surfaces of a net with a net as a core material. Since it is provided integrally on both the front and back surfaces of the net through the mesh, it has been proven that it does not crack even if it is bent at an acute angle, and the net protects the thick film layer and has a flexible smooth surface It becomes the material of the shape. In addition, since the thick film layer is made of a solventless paint, the characteristics of the material can be effectively exhibited, and it can be easily manufactured.
Further, even when the lubricating coating material according to the present invention is nailed with a nail, its fixing strength is reliably maintained by the net of the core material, and the lubricating coating material can be easily and firmly adhered to the surface to be coated such as concrete. It is.
