Abstract

The invention discloses a low-fogging polyurethane composition, which consists of a component A and a component B, wherein the component A consists of polyether polyol, polymer polyol, a cross-linking agent, a foaming agent, a foam stabilizer and a catalyst; and the component B consists of polyether polyol, isocyanate and a prepolymer made from a storage stabilizer. When the low-fogging polyurethane composition is used, the component A and the component B are mixed according to the isocyanate index of 1.05 for injection molding, and mold opening is performed within 4-6 minutes. A product produced from the polyurethane composition is widely applied to the industries of automobiles, furniture, toys and the like by virtue of the advantages of high environmental friendliness, low VOC (Volatile Organic Compound) value and comfortableness.

Description

technical field [0001] The invention provides a method for preparing a low-atomization polyurethane composition. The polyurethane composition is widely used in industries such as automobiles, furniture, and toys because of its excellent environmental protection, low VOC value, and comfort. Background technique [0002] Total volatile organic compounds (TVOC) refer to organic compounds whose saturated vapor pressure exceeds 133.32 Pa at room temperature, whose boiling point is below 250°C, and which can evaporate in the air at room temperature. It is toxic, irritating, and carcinogenic Sex and special odor, will affect the skin and mucous membranes, and cause acute damage to the human body. The World Health Organization (WHO), the National Academy of Sciences / National Research Council (NAS / NRC) and other institutions have always emphasized that TVOC is an important class of air pollutants. [0003] Government agencies around the world are now developing various independent p...
