Abstract

The invention discloses a polyvinyl butyral foamed material, which belongs to the field of high molecular materials. Recycled waste and used polyvinyl butyral is taken as a main raw material; rubber or an elastomer is taken as a main auxiliary material; a foaming agent, a foaming auxiliary agent, a plasticizing agent, a foamed hole nucleating agent, a foamed hole regulating agent, a crosslinking agent, a filler and the like are taken as the auxiliary materials; all the materials are mixed in a high-speed mixing machine at high speed, melted and blended in an extruding machine or an enclosed mixing machine, and formed through compression molding foaming in a flat-plate vulcanizing machine to obtain a polymer foamed material. The foamed material has excellent performance of an elastomer foamed material, has excellent cohesive property, is easy to process, and can be changed from wastes to valuables.

Description

technical field [0001] The invention relates to a polyvinyl butyral foaming material and belongs to the field of polymer materials. Background technique [0002] Due to the large number of bubbles inside the polymer foam material, it is not only light in weight and saves materials, but also has low thermal conductivity, good heat insulation performance, can absorb impact load, has excellent cushioning performance, sound insulation performance and high specific strength, etc. , agriculture, military, daily necessities and office supplies are widely used. [0003] Generally speaking, traditional polymer foaming materials can be roughly divided into plastic foaming materials and elastomer foaming materials according to the different raw materials used. Traditional plastic foaming materials have the advantages of simple formula, easy coloring and easy molding. It has the advantages of being processed into products with complex shapes, but its disadvantage is that its own elasti...
