A kind of flame-retardant antifouling synthetic leather and preparation method thereof

Abstract

The invention provides a method for preparing flame-retardant and antifouling synthetic leather, comprising the following steps: step S1, configuring slurry, step S2, finishing, step S3, curing, drying and molding; the slurry includes the following parts by weight: Raw materials: 90-100 parts of fluorine-containing phenyltriazine-based silicone-modified polyurethane, 30-50 parts of methyl ethyl ketone, 10-15 parts of natural capsaicin, 8-12 parts of 1-trifluoromethylvinyl boronic acid, trigger 0.5-0.8 parts of agent, 6-10 parts of surface modified attapulgite clay. The invention also discloses the flame retardant and antifouling synthetic leather prepared according to the preparation method of the flame retardant and antifouling synthetic leather. The flame-retardant and anti-fouling synthetic leather disclosed by the invention has excellent flame-retardant, anti-fouling, wear-resistant and scratch-resistant properties, and has good safety in use.

Description

technical field [0001] The invention relates to the technical field of synthetic leather, in particular to a flame-retardant antifouling synthetic leather and a preparation method thereof. Background technique [0002] In recent years, with the development of the economy and the improvement of living standards, people's demand for improving the quality of life is becoming more and more urgent, and the demand for high-quality daily products is also increasing. As a common daily product, leather products naturally have great market potential. However, with the enhancement of animal protection awareness, animal leather can no longer meet people's needs. As a substitute material for leather, synthetic leather products have entered the market. People's lives are widely used in the production of clothing, bags and footwear. [0003] Synthetic leather is a plastic product that simulates the composition and structure of natural leather and can be used as its substitute material. It...

Problems solved by technology

At present, the popular synthetic leather on the market is polyurethane synthetic leather. This kind of material has very good properties such as wear resistance and scratch resistance. However, its weather resistance, flame resistance and antifouling properties are very poor, which limits its application in some industries. widely used

Synthetic leather made of silica gel is another common type of synthetic leather. This material has the characteristics of environmental protection, non-hydrolysis, non-yellowing, and excellent weather resistance, but its wear resistance and scratch resistance are poor.

[0004] Chinese patent CN201610726984.0 proposes the method of modifying silicone polyurethane resin to produce synthetic leather. The synthetic leather has good biocompatibility of silicone, and also overcomes the problems of poor water resistance, antifouling and flame retardancy of polyurethane , but the transfer film and the impregnated cloth-based lamination in this invention need to be cured for 24-36 hours, and the time is too long, which affects production efficiency

The composition of the antifouling agent is complex, the price is high, and the performance stability needs to be further improved
