Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for forming a synthetic resin coating having a wrinkle pattern on the surface of a product.

Layering a synthetic resin film on the surface of cloth products such as gloves and socks and other product materials to provide reinforcement, waterproofing effects, and decorative effects is widely used in various industries including the glove and bag industry. However, since the synthetic resin coating usually has a smooth surface, it is slippery and has a poor aesthetic appearance.

The present invention was completed with the aim of providing a method for forming a synthetic resin coating on the surface of a product with a wrinkle pattern that can easily form a synthetic resin coating without the above-mentioned difficulties. A coating film of plastisol or organosol of vinyl chloride resin is formed on the surface of the coating film, and coarse particles of vinyl chloride resin are adhered in a thin layer without any gaps to the desired parts of the surface of the coating film, and heated for several seconds under high heat of 600 ° C or more, It is characterized in that it is then gelled at a normal gelling temperature.

The product materials used in the present invention are mainly knitted or woven gloves, bags, and other cloth materials, but are not limited to cloth materials, and the product materials are kept in shape and are A coating film of plastisol or organosol of vinyl chloride resin is formed on desired areas of the surface by known means such as dipping, coating, and pouring.
Next, coarse particles of vinyl chloride resin are adhered in a thin layer without any gaps to the required areas on the surface of the plastisol or organosol coating, that is, to all or part of the surface. The particle size of the coarse particles of the vinyl chloride resin is not particularly limited, but from the viewpoint of the purpose, it is preferably around 60 mesh passes. Some of these coarse particles are buried in the coating film of plastisol or organosol, while others are simply attached to the surface. Next, if this is heated for 2 to 8 seconds at a high temperature of 600°C or higher, preferably 800 to 1000°C, using a gas burner or infrared heater, coarse particles will adhere in a thin layer near the surface of the plastisol or organosol coating. Because of this, it has little fluidity, whereas the part below it has fluidity, so when it is rapidly heated for a few seconds at high heat, only the area near the surface where the coarse particles are attached will start to gel, but the inside part will have no fluidity. Due to the uneven penetration of heat, the expansion becomes non-uniform.Furthermore, because the temperature rises rapidly on the surface, non-uniform expansion occurs due to the migration of plasticizer, and due to these two non-uniform expansions, the surface Coarse particles result in the formation of irregular wrinkle patterns that lack smoothness, so the particles are cooled once or, if necessary, without being cooled, dipped in DOP to promote wrinkle formation, and then treated with normal If it is gelled by placing it in an air bath at the gelling temperature of 180°C to 250°C for 10 to 20 minutes, a synthetic resin film with a wrinkle pattern roughened by coarse particles will be formed on the surface. becomes. The reason why the initial heating condition was set to 600℃ or higher for several seconds is because if the temperature is lower than 600℃, it will not be possible to properly gel only the area near the surface of the coating film where coarse particles are attached. If the coating is heated at 600° C. or lower for a period of time for gelation to occur, gelation will proceed not only near the surface of the coating but also inside the coating, causing uniform expansion and preventing the formation of the desired wrinkle pattern.

The products obtained in this way, for example, in the case of cloth gloves, have a synthetic resin coating with a wrinkle pattern formed on the desired surface of the gloves, which not only exhibits reinforcing and waterproof effects, but also Its surface is hard to slip and has an interesting aesthetic appearance due to the wrinkled pattern made of coarse particles. If the coarse particles of vinyl chloride resin are of a different color from the coating film of plastisol or organosol of vinyl chloride resin, the decorative effect will be even better.

As is clear from the above description, the present invention provides a wrinkle patterned synthetic resin coating with excellent anti-slip effect and decorative effect on coarse particles of vinyl chloride resin before the gelling process of plastisol or organosol of vinyl chloride resin. It can be easily obtained by a simple method of attaching a substance and exposing it to high heat for a very short period of time, and its contribution to the development of industry is extremely large.

Example 1 A cloth glove was used as a material, a glove shape was inserted into it as a shape retainer, and 100% of vinyl chloride resin fine powder was added.
(parts by weight, the same applies hereinafter), 130 parts of DOP, and 2 parts of barium stearate are applied uniformly over the entire surface of the gloves by a coating method, and then vinyl chloride with a particle size of 60 mesh is applied to the surface. Coarse particles consisting of 95 parts of resin, 3 parts of red iron oxide, and 2 parts of barium stearate were uniformly adhered in a thin layer without any gaps, heated for 5 seconds in a gas flame at 800℃, and then rapidly cooled in an air bath at 200℃.
Heat to gel for 10 minutes.

Example 2 A cloth glove was used as a material, a glove mold was inserted into it as a shape retainer, and 100 parts of vinyl chloride resin,
A yellow organosol consisting of 130 parts of DOP and 2 parts of barium stearate is uniformly deposited in a thin film over the entire surface of the glove by a pouring method,
Next, coarse particles consisting of 95 parts of vinyl chloride resin with a particle size of 60 mesh pass, 3 parts of red iron oxide, and 2 parts of barium stearate were uniformly adhered to this surface in a thin layer without any gaps, and then heated in a gas flame at 900 to 1000°C. Exposure is performed 10 times for 0.2 seconds at 1 second intervals, followed by heating and gelling in an air bath at 200° C. for 10 minutes.
