Abstract
(EN)
Disclosed is a low-density rigid polyurethane foam, which is prepared by pre-mixing separately a component A and a component B, then mixing same together and foaming, wherein in parts by weight, the component A comprises: (1) 100 parts of a composite polyol; (2) 5-15 parts of cyclopentane; (3) 1.5-6 parts of an amine catalyst; (4) 1-5 parts of a silicon surfactant; and (5) 0.8-2.5 parts of water; the component B comprises: (1) 1-10 parts of butane; and (2) 120-220 parts of isocyanate. The raw materials are based on 100 parts of the composite polyol. The preparation method comprises the following steps: (1) preparing a component A; (2) preparing a component B; (3) injecting the component A and the component B into a closed mold, fully reacting, and demolding to obtain a rigid polyurethane foam. By means of the technology, a low-density rigid polyurethane foam which is environmentally-friendly and has excellent performance is prepared.
