Abstract

The invention discloses a polyurethane foam, which is made of the following raw materials in parts by weight: m-pentadecylphenol polyether polyol 90-100; polymethylene polyphenyl isocyanate 100-110; expandable graphite 25-100 30; foam stabilizer 1-2; foaming agent 20-25; the said m-pentadecylphenol polyether polyol is made of the following raw materials in parts by weight: m-pentadecylphenol 20-25; Ethanolamine 15-20; formaldehyde 3-4; triethylamine 0.5-1; propylene oxide 3-4. The m-pentadecylphenol used in the formula of the present invention is extracted from natural cashew nut shells. It is a biomass raw material and an ideal substitute for petrochemical raw material phenol. It has the advantages of non-toxicity and degradability, and the formula of the present invention Expandable graphite is added as a flame retardant, which effectively reduces the risk of flammability of polyurethane foam.

Description

technical field [0001] The invention relates to the field of plastic foam, in particular to a polyurethane foam. Background technique [0002] Polyurethane foam is an organic polymer material with low density, large specific surface area, and excellent elasticity. It is widely used in cushioning materials and other fields. Polyurethane foam is made of polyether and isocyanate as the main raw materials. Synthesized under the action of catalyst. Most of the raw materials of polyether produced at present are phenol with high toxicity and corrosiveness prepared from petrochemical raw materials, and the extensive use of fossil resources has also caused pollution problems, and polyurethane foam also has the disadvantage of being flammable. [0003] At present, the planting area of ​​cashew nuts in the world has reached more than 3.06 million hectares. A kind of cardanol, namely m-pentadecylphenol, can be extracted from natural cashew nut shells, which has become one of the import...
