Problems solved by technology

[0003] Polyurethane synthetic leather is mainly processed by dry and wet methods. Since its main elements are carbon, hydrogen, nitrogen, and oxygen, the two elements of carbon and hydrogen have the disadvantage of being flammable, and the combustion of carbon and hydrogen will produce a lot of toxic smoke. and gas, making polyurethane synthetic leather bring comfort and convenience to people's production and life, but also leaves a huge safety hazard
PU synthetic leather mainly achieves the purpose of flame retardancy by adding flame retardants or modified polyurethane, but most of the added flame retardants will affect the physical properties and feel of PU synthetic leather, while the flame retardant effect of PU synthetic leather obtained by modified polyurethane is not as good as that of PU synthetic leather. not ideal

Abstract

The invention discloses a halogen-free flame-retardant silicone rubber leather, which is prepared from the raw materials in parts by mass: 100 to 150 parts of low-viscosity vinyl fluorine-containing silicone oil, 30 to 50 parts of hydrophobic white carbon black, 20 to 30 parts of inorganic filler, 5 to 20 parts of hydrogen-containing silicone oil , 0.1 to 0.5 part of platinum catalyst, 5 to 20 parts of color paste pigment, 3 to 10 parts of low-viscosity hydroxyl silicone oil, and 0.02 to 0.1 part of inhibitor. The invention also discloses a coating process of the halogen-free flame-retardant silicone rubber leather. The coating process provided by the invention is simple in process, high in production efficiency and low in production cost, and the prepared halogen-free flame-retardant silicone rubber leather cannot damage a hand feeling and a physical property of silicone rubber, and has a favorable flame retardant effect at the same time.

Description

technical field [0001] The invention relates to the technical field of organosilicon and leather manufacturing, in particular to a halogen-free flame-retardant silicone rubber leather and a coating process for the halogen-free flame-retardant silicone rubber leather. Background technique [0002] After years of development, polyurethane synthetic leather has been widely used in industrial, civil and military fields due to its good appearance and feel, wear resistance, solvent resistance, high strength and wide application, and is closely related to people's production and life. [0003] Polyurethane synthetic leather is mainly processed by dry and wet methods. Since its main elements are carbon, hydrogen, nitrogen, and oxygen, the two elements of carbon and hydrogen have the disadvantage of being flammable, and the combustion of carbon and hydrogen will produce a lot of toxic smoke. and gas, making polyurethane synthetic leather bring comfort and convenience to people's prod...
