Silicon rubber polymer weather-resisting leather and preparation method thereof

Abstract

The invention provides modified silicon rubber polymer weather-resisting leather and a preparation method thereof. The modified silicon rubber polymer weather-resisting leather is composed of a modified silicon rubber polymer layer, a liquid silicon rubber polymer adhesive layer and a base material layer, wherein alkyd modified silicon resin, polyester modified silicon resin, acrylic modified silicon resin, epoxy modified resin, phenol-formaldehyde modified silicon resin and polyimide modified silicon resin are added into the modified silicon rubber polymer layer and the liquid silicon rubber polymer adhesive layer. The leather provided by the invention has certain special performance (including weather resistance, high air permeability, chemical reagent resistance, high bending resistance, high surface rigidity, high temperature and low temperature resistance, thermal adhesion resistance, hydrophobicity, corrosion resistance and radiation resistance); an application range of organic silicon leather in a special environment is expanded. Meanwhile, a manufacturing method thereof is simple, can be used for continuously producing and has high efficiency; in a whole production process and a whole utilization process, no harmful substances and no pollutants are formed.

Description

technical field [0001] The invention relates to the field of artificial organic leather, in particular to a silicone rubber polymer weather-resistant leather. Background technique [0002] At present, the synthetic leather industry at home and abroad is mainly based on polyurethane (PU) and polyvinyl chloride (PVC), which will contain a large amount of harmful substances such as dimethylformamide, methyl ethyl ketone, and toluene in the process of manufacture and use, and its Hydrogen chloride, dioxin, hydrogen cyanide and other decomposition products harmful to the environment and organisms will be produced during waste recycling. PU and PVC synthetic leather still have disadvantages such as aging resistance, temperature resistance, easy hydrolysis, easy staining, poor air permeability, resistance to twists and turns, resistance to hot water, and waste of resources due to excessive production processes in daily use. The existing organic silicon leather needs to overcome th...
