Abstract

A dampness-proof and anti-microbial PU resin and a preparation method thereof. The dampness-proof and anti-microbial PU resin comprises following raw materials, by mass, 88-90 parts of PU resin, 15-18 parts of nano titanium dioxide, 10-12 parts of tourmaline powder, 5-8 parts of polyethylene wax, 1-5 parts of bamboo charcoal powder and 5-8 parts of silicone powder, According to the invention, the PU resin, the nano titanium dioxide, the tourmaline powder, the polyethylene wax, the bamboo charcoal powder and the silicone powder are reasonably compounded. A prepared modified PU resin is excellent in anti-microbial performance and a dampness-proof performance.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a moisture-proof and antibacterial PU resin and a preparation method thereof. Background technique [0002] PU resin is polyurethane resin, which is an important type of synthetic resin, which is prepared by the reaction of polyisocyanate and polyol. The synthesis of PU resin is not only related to raw materials, but also has a lot to do with the additives and solvents used in the reaction. There are many types of PU artificial leather on the market today, but it is easy to breed mold in a humid environment, and its moisture-proof and antibacterial properties are poor. [0003] To sum up, how to overcome the deficiencies of the prior art has become an urgent problem to be solved in the prior art. Contents of the invention [0004] The purpose of the present invention is to overcome the deficiencies of the prior art and propose a moisture-proof and antibacterial PU...
