Abstract

The invention relates to a low-volatility self-catalytic conjugate polyether glycol which is characterized by comprising the following raw materials in parts by weight: 55-68 parts of polyether glycol A, 15-25 parts of polyester glycol B, 17-20 parts of self-catalytic polyester glycol, 5-8 parts of low-volatility reactive catalyst, 1-2 parts of organic tin catalyst, 1.5-3.0 parts of silicone oil,1.0-1.5 parts of deionized water and 20-26 parts of foaming agent, wherein the polyether glycol A is polyester 4110 or 403, and the polyether glycol B is polyester SA380 or YD-6205. The invention hasreasonable proportion, viscosity of 650-750mPa.s and better storage stability; in the preparation process, the conjugate polyether glycol has no volatility of stimulating and toxic gases when reacting with isocyanate in a foaming way, and can effectively protect the health of the production staff and the user; and polyurethane plastic foams obtained when the conjugate polyether glycol reacts withthe isocyanate have no residual smell, are thin and smooth, and have the advantages of proper density and good size stability.

Description

technical field [0001] The invention relates to a low-volatility self-catalyzed combined polyether polyol. Background technique [0002] Polyurethane foam is a good thermal insulation material, which has been widely used in indoor furniture, refrigerators, water heaters, containers, building insulation and other fields, and is playing an increasingly important role in the national economy. The preparation of polyurethane foam is based on polyisocyanate and high molecular weight polyol as the main raw materials, and essential additives such as foam stabilizer, catalyst, and blowing agent are added. In particular, the catalyst enables the foaming reaction to proceed, and can adjust the performance of polyurethane foam in a wide range to meet different application requirements. Commonly used catalysts are divided into tertiary amines and organotin compounds. Since most catalysts generally do not participate in the reaction, they will penetrate and migrate into the environment ...
