Problems solved by technology

[0002] Nowadays, the packaging of products mostly adopts molded or assembled polystyrene, the mold cost is high, and it is suitable for mass production; the spliced ​​polystyrene has poor mechanical properties and is easily broken by impact
However, traditional polyurethane foam packaging materials are inseparable from foaming agents. Most of the foaming agents used in polyurethane are destructive to the atmosphere or are flammable and explosive, have low safety factors, and are not conducive to environmental protection.

Abstract

The invention discloses an environment-friendly high-buffering-property polyurethane packaging material. The packaging material is formed by mixing a combined polyether raw material and polymethylene polyphenyl isocyanate, wherein the combined polyether raw material is composed of, by proportion, 40-45 parts of polyether trihydric alcohol, 30-40 parts of polyether glycol, 3-8 parts of chain extenders, 2-5 parts of foam stabilizers, 20-30 parts of water, 0.3-0.6 part of dimethylamino ethylether and 0.3-0.5 part of triethylene diamine. The proportion of the polymethylene polyphenyl isocyanate to the combined polyether raw material is 0.8-1.0:1. The material has a good buffering property, the buffering property is three times that of a general foaming material, and the material has good elasticity, and can be used repeatedly, and foamed and formed into the packaging material anytime and anywhere within a short time; as the water is used for replacing other foaming agents, intensity is low, the production cost is reduced, substances damaging an ozone layer are avoided, pollution is really reduced, and the environment-friendly effect of the foaming agent is completely achieved.
