Problems solved by technology

[0003] Polyurethane catalysts are generally organic compounds containing metal elements, such as lead, mercury, tin and other organic substances, which have high biological toxicity. With the continuous improvement of environmental protection requirements at home and abroad, these highly toxic catalysts are used in many polyurethane products. Gradually restrict or ban the use of
Zinc and bismuth series organic catalysts have gradually been applied as low-toxicity, safe and environmentally friendly polyurethane catalysts, but the catalytic activity of such catalysts is low, and their catalytic efficiency in the polyurethane polymerization process is significantly lower than that of lead, mercury, and tin A series of organic compounds will also reduce the comprehensive performance of polyurethane, so the use and development of polyurethane synthesis are limited

Abstract

The invention relates to the technical field of polyurethane synthesis, in particular to an environment-friendly compound polyurethane catalyst for polyurethane, which is prepared from the following raw materials in percentage by weight: 40 to 50 percent of bismuth compound, 20 to 30 percent of zinc compound, 10 to 20 percent of stannous compound and 20 to 40 percent of solvent. When the compound catalyst is used in polyurethane, the gelation efficiency is high, the peel strength after gelation is excellent, the biotoxicity is obviously lower than that of lead, mercury and tin organic compound catalysts, and the safety is higher.

Description

technical field [0001] The invention relates to the technical field of polyurethane synthesis, in particular to an environment-friendly composite polyurethane catalyst for polyurethane. Background technique [0002] As a polymer material, polyurethane is widely used in production and life, and in the polymerization process, catalysts must be used to ensure the completion of the polymerization reaction, and various series of catalysts are also in the development process of polyurethane synthesis. development and application. [0003] Polyurethane catalysts are generally organic compounds containing metal elements, such as lead, mercury, tin and other organic substances, which have high biological toxicity. With the continuous improvement of environmental protection requirements at home and abroad, these highly toxic catalysts are used in many polyurethane products. Gradually restrict or prohibit use. Zinc and bismuth series organic catalysts have gradually been applied as l...
