Reclaimed polyurethane sponge particle glue-combined foaming elastomeric material

Abstract

The invention provides a reclaimed polyurethane sponge particle glue-combined foaming elastomeric material, comprising reclaimed sponge particles, glue and a solvent. The material is characterized in that a formula of the material comprises a plasticizer, a particle surface modifier and nanometer silica, wherein the particle surface modifier is composed of dimethyl formamide, dioctyl phthalate and a silane coupling agent. The foaming elastomeric material prepared by the invention has the beneficial effects that under the action of dimethyl formamide, the silane coupling agent infiltrates into particle surfaces and the particle surfaces carry a great number of groups; when the nanometer enhanced glue is bonded with the groups on the particle surfaces, glue combination strength among the particles is improved; under the action of high temperature steam, volatile matters in the glue volatilizes, so micropores are formed in colloids and molecular chains polymerize to form novel molecular structures which are distributed among the particles; and the prepared foaming elastomeric material has good tensile strength, elasticity and hardness resistance, is widely applicable to fields like cars, boats, sports, decoration, the shoe industry and the like, and is a critical damping, sound-absorbing and warming material.

Description

technical field [0001] The invention relates to a polymer elastic material, which belongs to the technical field of chemical industry, and is specifically described as a regenerated polyurethane sponge particle glued foam elastic material. Background technique [0002] The production of sponge elastomer materials and the production of products inevitably produce many edges, corners, waste materials and crusts. These materials are large in volume and quantity, occupy a large area, are flammable, and are difficult to store. At present, there are also many processing recycled sponges. Manufacturers basically crush sponges, add glue and form extensive processing. The processed recycled sponges have insufficient tension, poor elasticity, and high cost. They are generally used in footwear, sports mats, and furniture products. Due to poor quality, waste products The rate is high, resulting in greater secondary waste. In order to make full use of resources and process recycled spon...
