Imitated silicon leather synthetic leather

Abstract

The invention relates to the field of synthetic leather manufacturing, and discloses imitated silicon leather synthetic leather, which comprises a surface layer, a middle layer, a bonding layer, a base cloth, a composite layer and a bottom cloth which are sequentially attached, wherein the surface layer is made of a polyurethane resin, an imitated silicon coating is formed on the surface layer through imprinting and punching treatment, a high-elasticity netted flame-retardant protection structure is arranged in the middle layer, and a bidirectional flame-retardant structure is uniformly laid in the composite layer. According to the invention, the imitated silicon coating is formed by imprinting and punching treatment, so that the cost is reduced, and the product has the soft and breathable performance of organic silicon leather at the same time; and after the crisscross fiber strips in the middle layer are broken, the elastic separation blades are mutually contacted and attached to generate superposition to form a protection structure, the flame retardant property of chloroprene rubber is used for blocking flames, and a microcapsule process is adopted in the composite layer, so that the consumption of a flame retardant is reduced, the flame retardant effect is played to the maximum extent, the effect range of the flame retardant is ensured not to be vacant, and sufficient flame retardant property is provided.

Description

technical field [0001] The invention relates to the field of synthetic leather production, in particular to a silicon-like synthetic leather. Background technique [0002] Silicone leather is a new type of environmentally friendly leather. It uses silica gel as its raw material. Solvent technology, coating and bonding silicone on various substrates to make leather, in order to reduce the cost of using silicone, there is a lot of room for research and development of silicon-like synthetic leather that can be used equally. [0003] The existing silicon-like synthetic leather has a relatively simple structure, and it is difficult to achieve effective unity in terms of softness, breathability and flame retardancy. Especially in terms of flame retardancy, existing synthetic leathers often directly combine flame retardants with Combining the materials of each layer consumes a lot of flame retardants and cannot guarantee the compatibility of the flame retardants with the materials...

[0003] The existing silicon-like synthetic leather has a relatively simple structure, and it is difficult to achieve effective unity in terms of softness, breathability and flame retardancy. Especially in terms of flame retardancy, existing synthetic leathers often directly combine flame retardants with The combination of materials in each layer consumes a lot of flame retardants and cannot guarantee the compatibility of flame retardants with materials in each layer, and flame retardant vacancies are prone to appear, so corresponding improvements are needed
