High-elastic environment-friendly rubber sheet for teaching head and manufacturing process thereof

Abstract

The invention discloses a high-elastic environment-friendly rubber sheet for a teaching head and a manufacturing process thereof, which relates to a product in the plastic field. The product comprises 80-100 parts of imported polyvinyl chloride (PVC) paste resin raw material, 100-150 parts of dioctyl phthalate, 2-4 parts of composite liquid stabilizer and 0.1-1 part of environment-friendly toner, and is molded by adopting a slush molding process. The manufacturing process comprises the following steps: grinding the toner; stirring; filtering; carrying out vacuum defoamation; and carrying out slush molding treatment. The slush molding treatment mainly comprises the following steps: putting a mold into a rubber heating furnace at 260-280 DEG C to be heated for 5-10s; then, taking out the mold, filling slurry, and standing for 10-15s; pouring the non-gelatinous slurry into a recovery tank; putting the mold into the rubber heating furnace again to be heated for 30-40s; taking out the mold, putting the mold into cooling water, and standing for 20-30s; and after the mold is cooled, taking the mold out of the water, and taking out burrs. The product integrates the characteristics of environment protection, flexibility, high elasticity and is convenient to use, uses more elastic materials, has stronger self-regulating property and wide application range, and can be used by a user conveniently.

Description

technical field [0001] The invention relates to products in the field of plastics, and is a hairdressing and beauty training teaching aid, in particular to a novel high-elastic face-cutting teaching head. Background technique [0002] At present, there are mainly the following types of teaching heads on the market. One is the combined teaching head. The combined teaching head is to insert the colored hair into the plastic model. The inside of the plastic model is filled with foam and the outer surface is made up. The disadvantages of this combination teaching head are High cost and little flexibility. Hairstyles can only be matched with the same face shape, skin color, makeup, etc. Various elements cannot be replaced with each other, and the purpose is single. The second is the ear-cutting training head. The ear-cutting teaching head itself has a face shape and makeup, and can be used with different bald heads. However, because the face shape and makeup are already carried ...

[0002] At present, there are mainly the following types of teaching heads on the market. One is the combined teaching head. The combined teaching head is to insert the colored hair into the plastic model. The inside of the plastic model is filled with foam and the outer surface is made up. The disadvantages of this combination teaching head are High cost and little flexibility

Hairstyles can only be matched with the same face shape, skin color, makeup, etc. Various elements cannot be replaced with each other, and the purpose is single

The second is the ear-cutting training head. The ear-cutting training head itself has a face shape and makeup, and can be used with different bald heads. However, because the face shape and makeup are already carried by itself, it still has certain limitations.

[0003] However, the rubber used in the face-cutting teaching head currently on the market is not environmentally friendly. It is relatively stiff and has poor elasticity, making it difficult to wear with the bald head. It does not stretch and shrink, and it cannot fit well with the bald head
