Problems solved by technology

However, PU and PVC resins will burn when they are heated and melted, and the flame retardant effect is very poor.
The general improvement measure in the synthetic leather industry is to add flame retardants, some of which add halogenated flame retardants and brominated flame retardants, which causes the problem that the products are not environmentally friendly, while some add a small amount of inorganic flame retardants to improve the flame retardancy. Not big, it will also have a great impact on other properties of the product, such as tensile, tearing, scratch resistance and other comprehensive properties, and the disadvantages are more obvious

Abstract

The invention discloses flame-retardant silica gel for synthetic leather. The flame-retardant silica gel consists of the following raw materials in parts by weight: 100 parts of vinyl polysiloxane, 5-10 parts of white carbon black, 0.15-0.8 part of an inhibitor, 0.3-0.8 part of a platinum catalyst, 5-10 parts of diatomite and 11-12 parts of hydrogen-containing silicone oil. The invention further discloses a preparation method of the flame-retardant silica gel for the synthetic leather. The flame-retardant silica gel for the synthetic leather is completely environment-friendly and can pass REACH detection; a used flame retardant cannot affect the physical properties of products, also has good flame resistance and can automatically extinguish when on fire.

Description

technical field [0001] The invention relates to the field of synthetic leather manufacturing, in particular to a flame-retardant silica gel for synthetic leather and a preparation method of the flame-retardant silica gel for synthetic leather. Background technique [0002] In the prior art, the mainstream synthetic leather in the current market is a product formed by coating resin slurry such as PU and PVC on the base material. However, PU and PVC resins will burn when they are heated and melted, and the flame retardant effect is very poor. The general improvement measure in the synthetic leather industry is to add flame retardants, some of which add halogenated flame retardants and brominated flame retardants, which causes the problem that the products are not environmentally friendly, while some add a small amount of inorganic flame retardants to improve the flame retardancy. It is not big, and it will also have a great impact on other properties of the product, such as t...
