Problems solved by technology

But the above-mentioned prior art only adopts adding organic montmorillonite to prepare polyurethane nanocomposites, although the modification effect on polyurethane materials is obvious, but because montmorillonite is a natural mineral, the purity and quality of montmorillonite fluctuate greatly, thereby leading to industrialization Poor product performance reproducibility

Abstract

The present invention discloses one kind of composite nano high-elasticity polyurethane material and its preparation process. The composite nano high-elasticity polyurethane material is prepared through mixing component A and component B in the ratio of 1 / 6 to 1 / 3, adding catalyst through stirring and curing. The component A is conventional polyurethane prepolymer; and the component B is prepared through mixing SiO2, ZnO and other granular nano material, laminated nano material hydrotalcite and polyether polyol, vacuum pumping to deair and dewater and adding other assistants. The composite nano material has outstanding high elasticity and raised comprehensive mechanical performance.

Description

【Field of Invention】 [0001] The invention relates to a high-elastic nanocomposite material, in particular, the invention relates to a high-elastic polyurethane inorganic nanocomposite material, and relates to the application of the composite material in high-elastic ground materials. The invention also relates to a manufacturing method of the high elastic polyurethane inorganic nanocomposite material. 【Background technique】 [0002] Polyurethane is an emerging material that has the characteristics of rubber and plastic, and its performance can be adjusted. The range of products made of polyurethane is very wide, including a series of products such as polyurethane foam plastics, elastomers, coatings, adhesives, synthetic fibers, synthetic leather, and waterproof materials. Polyurethane synthetic materials have properties unmatched by any other commercial rubber and plastic, such as abrasion resistance, high strength (tensile strength, tear strength), high elongation, high el...
