Abstract

The invention discloses a polyurethane foaming white material. The polyurethane foaming white material comprises combined polyether, a foaming agent and a trimerization type catalyst, wherein the foaming agent comprises trans-1-chloro-3, 3, 3-trifluoropropene, and the trimerization type catalyst is (2-hydroxypropyl) trimethyl ammonium formate. The invention further provides a polyurethane composition. The polyurethane foaming white material has stability in storage, and after the polyurethane foaming white material is placed at room temperature for 1 month, the foaming reaction speed of the polyurethane composition and the heat conduction coefficient of foam are basically unchanged.

Description

technical field

[0001] The invention relates to the field of rigid polyurethane foam materials, in particular to a polyurethane foam white material and a polyurethane composition. Background technique

[0002] Trimeric catalysts commonly used in rigid polyurethanes are mainly tris(dimethylaminopropyl)hexahydrotriazine or tris(dimethylaminomethyl)-2,4,6-phenol, which can speed up the formation of foam Post-curing, improving mold release, suitable for rigid polyurethane foam compositions of cyclopentane foaming systems and hydrofluorocarbons (Hydrofluorocarbons, HFCs) foaming systems (rigid polyurethane foam combinations or rigid polyurethane foam foaming materials ).

[0003] In response to the current energy efficiency upgrade and the EU's January 1, 2015 GWP<150 (Global Warming Potential, global warming potential) new regulations, trans-1-chloro-3,3,3-trifluoropropene (HFO-1233zd , trade name LAB) as a new type of environmentally friendly and efficient fourth-generatio...
