Description

The present invention relates to a method for producing a light lava plate material, and in particular, to a shredded lava and cement addition amount according to a predetermined ratio, a different ratio of water ratio, foaming agent addition amount, coloring material addition amount, and different shredded lava The present invention relates to a material that adjusts the density, porosity, and water absorption rate of light lava plate materials in accordance with particle size and the like.

With the development of science and technology, human beings place importance on comfort, convenience, safety, etc., and porous light materials are being used greatly in response to demands such as vibration isolation, sound absorption, heat insulation, and light weight.

For example, a plate material obtained by mixing wood fiber, an adhesive, a foaming agent, and a light heat insulating material is described in the Chinese Patent No. M477855 “Lightweight fireproof heat insulating plate material”. Wood fiber can be lightweight and fire proof through the fire treatment procedure, but it contains a relatively large amount of added material, and even if wood fiber is subjected to fire treatment, the degree of fire resistance is worse than that of inorganic materials. Also, the manufacturing process is complicated, expensive and inconvenient.

In addition, the Chinese Patent No. M591064 “Method for producing light plate material” describes a method for producing a plate material by pressing a bridge-type foam material and a heat-fixable binder under high temperature and high pressure. The plate material is stronger in ductility than a general thermoplastic material, but has a high temperature resistance that is still lower than that of an inorganic material, so that it needs to be strengthened by adding another material, and thus the cost becomes high.

In addition, for example, the use of plastic foam with a mixed layer composed of a foam material in which wood material is used as the surface layer and cement is mixed as the middle layer material in the M31423 “Composite light plate material structure” However, by reinforcing each other with three layers of different materials, the functions of light weight, sound absorption and fire prevention are realized, but since these three layers of materials are combined with an adhesive, the production procedure is reduced and the cost is also reduced. Get higher.

As described above, the light product manufactured by each of the above-mentioned methods has advantages such as light weight, flame resistance and sound absorption, but has a disadvantage that the production cost is relatively high, and the low cost is taken into consideration. It is disadvantageous and the manufacturing process is complicated, so there is a problem of indirectly wasting resources. Therefore, it cannot be said that a general conventional one is practical.

The main object of the present invention is to combine the chopped lava and cement addition amount at a predetermined ratio with different ratios such as the addition ratio of water , foaming agent, colorant addition amount, different chopped lava particle size, etc. Provided is a method for producing a light lava plate which can obtain advantages such as excellent light weight, sound absorption and heat insulation by adjusting the density, porosity and water absorption rate of the light lava plate. Hydrolysis ratio is in the added water and the ratio of the solid content, a weight sum of shredded lava cement or white cement is its solid.

Another object of the present invention is to provide a light lava plate material having high added value, which can reuse waste resources by using shredded lava particles produced from waste as a raw material.

In order to achieve the above object, the present invention first selects a plasma lava, and pulverizes, polishes and sorts the plasma lava into a lava powder having a uniform particle size, and stores the lava powder. Dry, then take out the lava powder and use it as a powder raw material to regenerate, and according to a predetermined water ratio , add a coloring material, cement, or white cement to perform a balance weighing process, and at the same time, a foaming agent Mixing and pouring water into the mold to pre-form the plate, and after pre-molding, the final molding of the light lava plate is performed by placing it in a room temperature environment, and the plate is taken out from the mold This is a method for producing a light foam lava plate material that is cut and finished to produce a light lava plate material having porous properties.

It is a figure and the result conceptual diagram of the 3rd particle size of the shredded lava of this invention. As shown in the figure, the present invention is a method for producing a light lava plate, at least (A) a step of selecting plasma lava 11 which is a chopped lava, and (B) pulverization and polishing selection for the plasma lava. Performing treatment 12 to obtain a lava powder having a uniform particle diameter through grinding, polishing, and selection; and performing powder storage treatment 13 on the lava powder, and then storing and drying the lava powder; (C) Next, the lava powder is taken out and used as a recycled powder raw material 14, and the lava powder is made into a lava powder slurry according to a predetermined hydration ratio , and the color material 15 or cement or white cement is added to the slurry. (16) After the balance measurement, the balance foaming agent 18 and the balance water 19 are mixed and stirred 20, mixed and stirred, and then injected into the mold to perform the injection process. 21 and A step of performing a preforming process 22 of the material; and (E) after the preforming, a room temperature standing process 23 of the final molding is performed by placing it in a room temperature environment, and the plate material and the formwork are separated after the room temperature standing process. Then, a step of obtaining a light lava plate material 25 (as shown in FIG. 5) having porous properties by taking out the plate material and performing the cutting / finishing process 24 is included .

By utilizing the present invention, the plasma lava can be produced into a light lava plate having porous properties. For example, the shredded lava is pulverized, ground, and sorted to give a particle size of 200 mesh ( using chopped lava powder is 80 mesh to mesh) without a mixing ratio of cement and base the amount of 50%, varied from 20% to 80% addition of water, for example, 0.25 to 0 A light lava board is produced with different hydration ratios such as .50, and with different foaming agent additions such as 1.0% to 4.0%.
