titleOfInvention | High open-cell flame-retardant polyurethane foam core material for vacuum insulation panel and preparation method thereof |
abstract | The invention relates to the technical field of polyurethane rigid foam, in particular to a high-opening flame-retardant polyurethane foam core material for vacuum insulation panels and a preparation method thereof. The high-open-cell flame-retardant polyurethane foam core material for vacuum insulation panels is composed of component A and component B, and component A includes 35-50 parts of polyether polyol and 10-15 parts of polyester polyol , 13-18 parts of flame retardant, 0.5-1.1 parts of deionized water, 7-17 parts of foaming agent, 2-4.4 parts of cell opener, 1-2 parts of foam stabilizer, 1-1.5 parts of anti-settling agent, catalyst 1-1.6 parts, 5-15 parts of zeolite powder; B component is polymethylene polyphenyl polyisocyanate. The high-open-cell flame-retardant polyurethane foam core material for the vacuum insulation panel of the invention has high foam strength, high open-cell ratio, good flame retardancy, adjustable density, and can be cut to make curved and angular vacuum insulation products, thereby expanding the vacuum The application field of the thermal insulation board; the present invention also provides a preparation method thereof. |
