PPU sealant applied to prefabricated buildings and manufacturing method of PPU sealant

Abstract

The invention relates to a PPU sealant applied to prefabricated buildings and a manufacturing method of the PPU sealant. The PPU sealant is prepared from plasticizer, BASF light stabilizer, PU (polyurethane) resin, nano calcium carbonate, titanium dioxide, a coupling agent, amine catalysts, a dispersing agent and an adhesion strength promoter. The PPU sealant has advantages of excellent weather resistance, durability, high deformation displacement resistance, great adhesion and coating performance, safety, environmental friendliness, high contamination resistance, convenience and quickness in construction and the like and can be popularized and applied in the current flourishing prefabricated building development environment.

Description

technical field [0001] The invention relates to the technical field of prefabricated buildings, in particular to a PPU sealant applied to prefabricated buildings and a manufacturing method thereof, which has excellent weather resistance, durability, high resistance to deformation and displacement, good adhesion and The advantages of paintability, safety and environmental protection, low contamination and quick and convenient construction can be promoted and applied in the current environment where prefabricated buildings are booming. Background technique [0002] Construction industrialization is a concept derived from the Western industrial revolution. Especially in developed countries such as Japan, Germany, and the United States, the application level of construction industrialization has exceeded 70%. Compared with Western developed countries, my country started late and still At the stage of exploration and immature technology, relevant norms and standards related to pre...

Problems solved by technology

Compared with the latter, the former is more cumbersome in the construction process.

The sealing materials used in the latter are mainly sealants, such as silicone sealants, polyurethane sealants, silane-modified polyether sealants, silane-modified polyurethane sealants, etc., but there are differences in the performance indicators of these sealants. In addition, due to
