Abstract

The invention discloses a preparation method of anti-molding intelligent temperature-adjustment polyurethane foam. Firstly, a halloysite nanotube is activated, then an organic phase-change material is dipped into the halloysite nanotube, one port of the halloysite nanotube is wrapped with 8-hydroxyquinoline, a plastic temperature-adjustment material with a port wrapped with 8-hydroxyquinoline is obtained through a complex reaction of 8-hydroxyquinoline and copper ions, the surface of the plastic temperature-adjustment material is modified with an amino group, finally, the modified plastic temperature-adjustment material is added to polyurethane foam to have a polymerization reaction, and the anti-molding intelligent temperature-adjustment polyurethane foam is prepared. The preparation method has the benefits as follows: (1), the halloysite nanotube can be taken as a container of the phase-change material and can also serve as a reinforcement material of the polyurethane foam; (2), a reaction happens at one port of the halloysite nanotube to generate 8-hydroxyquinoline and copper complex, so that the phase-change material can be prevented from flowing out of the halloysite nanotube, and the complex can serve as an anti-mildew agent; (3), the amino group on the surface of the plastic temperature-adjustment material enables the material to be tightly combined with the foam.

Description

technical field [0001] The invention relates to a method for preparing a temperature-regulating polyurethane foam, in particular to a method for preparing a mildew-proof intelligent temperature-regulating polyurethane foam. Background technique [0002] Polyurethane foam is an important synthetic material, which has the characteristics of porosity, low relative density and high specific strength, and has a wide range of uses. From a global perspective, blocky flexible polyurethane foam is mainly used in furniture, pads, composite fabrics, clothing, shoes and hats, and luggage lining materials. Rigid polyurethane foam is mainly used in the construction industry, refrigeration equipment such as refrigerators, freezers, refrigerated transport vehicles, pipelines, large storage tanks, etc. It has also developed rapidly in the fields of furniture industry, decoration industry, and household appliances. At present, the annual output of soft polyurethane foam in my country is esti...
