Embodiment 1

[0023] A silicone leather applied to vehicle interiors or seats, which consists of a surface layer, an intermediate base material layer, a bottom layer, and a base fabric layer bonded in sequence. The base fabric of the base fabric layer is knitted fabric.

[0024] The surface layer contains the following components in parts by weight: 100 parts of organic silica gel P40, 10 parts of P4 hardener, and 5 parts of nano-silica with a particle size of 10-30 nm;

[0025] The intermediate base material layer contains the following components in parts by weight: 100 parts of silicone P41, 10 parts of P4 hardener, and 8 parts of solvent-free environmentally friendly silicone toner;

[0026] The bottom layer contains the following components in parts by weight: 100 parts of organic silica gel P42, 10 parts of P4 hardener, 2 parts of nano-silica with a particle size of 10-30nm, and 5 parts of vinyl tris(β-methoxyethoxy)silane ;

[0027] Organic silica gel P40, P41, and P42 are polysilox...

Embodiment 2

[0033] The difference between the silicone leather applied to vehicle interiors or seats provided in this example and Example 1 is that the surface layer comprises the following components in parts by weight: 80 parts of organic silica gel P4080 parts, 10 parts of P4 hardener, 10 parts ~30nm nano silicon dioxide 3 parts;

[0034] The intermediate base material layer contains the following components in parts by weight: 180 parts of organic silica gel P4, 10 parts of P4 hardener, and 25 parts of solvent-free environment-friendly silicone toner;

[0035] The bottom layer contains the following components in parts by weight: 100 parts of organic silica gel P42, 10 parts of P4 hardener, 5 parts of nano-silica with a particle size of 10-30nm, γ-(2,3-epoxypropoxy)propyl trimethyl 2 parts of oxysilane.

[0036] The preparation method of the above-mentioned silicone leather applied to vehicle interiors or seats is basically the same as that in Example 1.

Embodiment 3

[0038] The difference between the silicone leather applied to vehicle interiors or seats provided in this example and Example 1 is that the surface layer comprises the following components in parts by weight: 120 parts of organic silica gel P40, 10 parts of P4 hardener, 10 parts ~30nm nano silicon dioxide 3 parts;

[0039] The intermediate base material layer contains the following components in parts by weight: 120 parts of organic silica gel P41, 10 parts of P4 hardener, 60 parts of solvent-free environment-friendly silicone toner;

[0040] The bottom layer contains the following components in parts by weight: 120 parts of organic silica gel P42, 10 parts of P4 hardener, 3 parts of nano-silica with a particle size of 10-30nm, γ-(2,3-epoxypropoxy)propyltrimethyl 5 parts of oxysilane.

[0041] The preparation method of the above-mentioned silicone leather applied to vehicle interiors or seats is basically the same as that in Example 1.

Abstract

The invention discloses a silicone leather applied to vehicle interiors or seats and a preparation method thereof. The silicone leather is formed by sequentially bonding a surface layer, an intermediate base material layer, a bottom layer, and a base cloth layer. The basic preparation raw materials for the intermediate base material layer and the bottom layer are organic silica gel, hardener, and vinyl silicone oil. In addition, the surface layer also contains nano-silica, and the bottom layer also contains nano-silica and a silane coupling agent. The preparation raw materials selected by the present invention are simple and easy to obtain, and the prepared silicone leather has good wear resistance, good weather resistance, good bonding effect, good resilience, soft and full hand feeling, comparable to genuine leather, and can be widely used in vehicles. The production of decorations or seats; at the same time, no toxic and harmful substances are used in the preparation process, no solvent is added, it is safe, environmentally friendly and pollution-free, and the produced silicone leather does not volatilize toxic and harmful substances when used, which is more beneficial to human health than traditional leather. and environmental safety.

Description

technical field [0001] The invention relates to the field of leather material preparation, in particular to a silicone leather applied to vehicle interiors or seats and a preparation method thereof. Background technique [0002] At present, the production processes of artificial leather and synthetic leather at home and abroad are mainly divided into dry polyurethane tanning process, wet polyurethane tanning process and water-based polyurethane process. These methods all will use solvent-based polyurethane resin in the production process, because the solvent-based polyurethane resin contains a large amount of poisonous and harmful chemical solvents such as dimethylformamide (DMF), toluene, methyl ethyl ketone, etc. The human body can cause great harm. [0003] Leather fabrics of vehicle interiors (such as interiors of ships, planes, trains, cars, etc.), seats (such as seats or cushions of ships, planes, trains, cars, electric vehicles, bicycles, etc.) Internal and external...
