| titleOfInvention | Combination material of insulation boards for producing building outer walls and preparation method thereof |
| abstract | The invention relates to a combination material of polyurethane insulation boards for producing building outer walls by using a continuous method and a preparation method thereof. The combination material is composed of a component A and a component B, a weight ratio of the component A to the component B is 1:1-1.3, wherein the component A is composed of the following components, by weight, of 20-40% of polyether polyol A, 15-35% of polyether polyol B, 10-20% of polyether polyol C, 1.0-3.0% of foam stabilizer, 1.0-3.0% of chemical foaming agent, 10-20% of physical foaming agent, 0.5-3.5% of catalytic agent and 10-20% of fire retardant, and the component B is polymethyl polyphenyl polyisocyanates. The preparation method of the combination material comprises stirring and mixing all components in the component A in proportion, and then mixing the component A with the component B. Polyurethane foams made of the combination material are low in heat conductivity coefficient, good in leakproofness, excellent in flame retardant property, good in product stability and capable of completely meeting requirements for polyurethane outer wall boards. |
