Problems solved by technology

[0004] However, the existing synthetic leather generally has the following disadvantages: 1. Usually, it can only be cleaned by dipping in water and cleaning with detergent, and gasoline cannot be used to completely remove stains, and dry cleaning cannot be used.
2. When washing with water, the water temperature should not exceed 40°C. However, the cleaning effect of low-temperature water washing is not good, and the best performance of the detergent cannot be exerted.
3. It cannot be exposed to the sun, so synthetic leather is easy to age and has poor weather resistance, and the use effect is not good in high temperature areas in the world
4. Due to the properties of synthetic leather, most synthetic leather cannot be exposed to organic solvents and is easily corroded
5. Synthetic leather is not resistant to folding, and will crease and crack after folding, especially in a humid environment
6. Synthetic leather is easy to stretch and start to mold in a humid environment, so the storage conditions are harsh

Embodiment 1

[0017] A kind of anti-tear synthetic leather slurry, its components and the mass parts of each component are: 4 parts of polybutadiene, 2 parts of polyvinyl chloride, 25 parts of polyacrylamide, 4 parts of methyl methacrylate , 4 parts of maleic anhydride, 0.4 parts of tributyl phosphate, 10 parts of cocklebur, 3 parts of polyvinylpyrrolidone, 4 parts of chlorite powder, and 2.5 parts of methyltriethoxysilane.

[0018] A kind of preparation method of the synthetic leather slurry of anti-tearing, comprises the following steps:

[0019] (1) Prepare Xanthium modified solvent: crush all dried Xanthium, add an appropriate amount of 0.1mol / L hydrochloric acid, stir evenly, and stand still for 20-30 minutes. The amount of hydrochloric acid added is based on completely submerging Xanthium. Accurately, after the soaking is completed, add an appropriate amount of ammonia monohydrate to the mixed solution of cocklebur and hydrochloric acid to make the mixed solution neutral; then mix the...

Abstract

The invention relates to an anti-tearing synthetic leather sizing agent and a preparation method thereof. The anti-tearing synthetic leather sizing agent comprises the following components in parts by mass: 4-7 parts of polybutadiene, 2-5 parts of polyvinyl chloride, 25-32 parts of polyacrylamide, 4-6 parts of methyl methacrylate, 4-7 parts of maleic anhydride, 0.4-0.8 part of tributyl phosphate, 10-13 parts of fructus xanthii, 3-4 parts of polyvinylpyrrolidone, 4-6 parts of chlorite powder and 2.5-4 parts of methyltriethoxysilane. Comprehensive properties of synthetic leather can be greatly improved, modified components can be used as a reinforcing agent and a packing powder material to modify the synthetic leather, and then the anti-tearing property of the synthetic leather can be improved; on one hand, a fiber reinforcing body has an environmental protection property, and on the other hand, the mass of the fiber reinforcing body is 40% lower than that of glass fiber.

Description

technical field [0001] The invention relates to the technical field of artificial leather slurry, in particular to a tear-resistant synthetic leather slurry and a preparation method thereof. Background technique [0002] However, with the growth of the world's population, the human's demand for both the total amount and the type of leather has doubled, and the limited amount of natural leather has long been unable to meet this demand of people. So scientists began to develop synthetic leather. [0003] Synthetic leather simulates the composition and structure of natural leather and can be used as a plastic product for its substitute material. In the production process of synthetic leather, the impregnated non-woven fabric is usually used as the mesh layer, and the microporous polyurethane layer is used as the grain layer. Its front and back are very similar to leather, and has a certain degree of air permeability, which is closer to natural leather than ordinary artificial...
