Abstract

The invention belongs to the technical field of premixed polyether, and particularly relates to premixed polyether, an anti-ageing full-water type foam board and a preparation method of the anti-ageing full-water type foam board. The premixed polyether is prepared from the following raw materials: polyether polyol A, polyether polyol B, polyether polyol C, polyether polyol D, a cross-linking agent, an antioxidant, a catalyst, a foam stabilizer, a chemical foaming agent, a flame retardant and a foaming additive. The full-water type foam board prepared from the premixed polyether, which is disclosed by the invention, is also processed at normal temperature and under normal pressure, is simple in process, is easy to operate, is low in volatilization, does not generate three wastes (waste gas,waste water and waste solid), and is short in production period, low in cost, high in efficiency and low in energy consumption.

Description

technical field [0001] The invention belongs to the technical field of combined polyether, and in particular relates to a combined polyether, anti-aging all-water foam board and a preparation method thereof. Background technique [0002] Rigid polyurethane foam has good thermal insulation performance, and at the same time has a high closed cell rate, and has a good moisture-proof, mildew-proof and moisture-proof function. With the promotion of the concept of energy saving and emission reduction in the whole society, its application is becoming more and more extensive. Due to its good construction performance and high production efficiency, polyurethane sheet has a wider range of applications. However, in some fields, such as polyurethane panels for thermal insulation of simple prefabricated houses, panels for sound insulation and heat insulation of anti-theft doors, panels for interior decoration insulation, panels for floor heating and heat insulation, etc., the polyuretha...
