Abstract

The invention discloses a bacteriostat polyurethane synthesizing material. The bacteriostat polyurethane synthesizing material is prepared through the following raw materials in parts by weight: 15-25parts of triethyl phosphate, 10-20 parts of sodium alginate, 80-100 parts of isocyanate, 80-100 parts of mixed polyol, 50-80 parts of mixed catalyst, 2-4 parts of diethanol amine, and 4-8 parts of vegetable fat; the mixed polyol is prepared by mixing polyether polyol and polymer polyol based on the ratio of 1: (1-2); the mixed catalyst is prepared by mixing a triethylene diamine liquid catalyst and an organic metal catalyst. The bacteriostat polyurethane synthesizing material is high in bacteriostat and antibacterial performance and can be prepared into daily products, and the daily productscan remain the bacteriostat effect for a long term, so that the sanitation and health of use are ensured.

Description

technical field [0001] The invention relates to a synthetic material, in particular to a bacteriostatic polyurethane synthetic material. Background technique [0002] Due to its unique structure and performance, polyurethane polymer materials are highly designable, with relative density wear resistance, water resistance, adjustable hardness, elasticity and shock absorption, etc., and can be widely used in various fields by selecting raw materials and reasonable and optimal formulas.
