Abstract

The invention discloses premixed polyether polyols and a raw material composite for polyurethane imitated wood and a using method of the raw material composite. The premixed polyether polyols comprise polyether polyol, a catalyst, a foam stabilizer, water and a physical foaming agent; the raw material composite further comprises isocyanate. The premixed polyether polyols are compounded by selecting polyether polyol with special types and ratios and other raw materials according to a suitable proportion; Ecomate foaming agent is adopted as the physical foaming agent; the premixed polyether polyols and the raw material composite for the polyurethane imitated wood has zero ozone consumption and a low greenhouse effect value, so that the polyurethane imitated wood with excellent mechanical performance, meets related standards of Montreal Protocol and Kyoto Protocol, has a good environmental effect, and has a good market application prospect.

Description

technical field [0001] The invention relates to a combination polyether of polyurethane imitation wood, a raw material composition and a use method thereof. Background technique [0002] Polyurethane foam is a porous polyurethane material composed of a large number of micropores and polyurethane resin pore walls. Low-density foam has the characteristics of good heat insulation effect, light weight, high specific strength, excellent chemical resistance and good sound insulation effect. What stands out is that its thermal insulation performance is superior to natural thermal insulation materials such as rock wool and synthetic materials such as expanded polystyrene, and has become an important class of synthetic resin thermal insulation materials; high-density polyurethane foam has high strength and can be used for Imitation wood products are characterized by lower density than wood and simple manufacturing process, and can be molded to manufacture various imitation carved woo...
