Abstract

The invention relates to a low-odor polyurethane open white primer and a preparation method thereof. The low-odor polyurethane open white primer is formed by mixing a main agent, a curing agent and a diluent by a mass ratio of (1-1.4):(0.5-0.7):(0.6-1), wherein the main agent, the curing agent and the diluents are respectively prepared from the following components in part by weight: the main agent comprises the following components in part by weight: 45-55 parts of alkyd resin, 0.1-0.5 part of a dispersing agent, 0.1-0.5 part of a defoaming agent, 3-7 parts of zinc powder, 0.2-0.6 part of bentonite, 2-7 parts of calcium carbonate, 18-25 parts of titanium dioxide, 2-7 parts of talcum powder, 10-15 parts of a mixed environment-friendly solvent, and 0.1-0.3 part of a drier. The prepared low-odor polyurethane open white primer has low odor after construction, a primer film can permeate on wood patterns well, and the covering capability and the environment protection property are good.

Description

technical field [0001] The invention relates to a paint for home decoration, in particular to a low-odor polyurethane open white primer and a preparation method thereof. Background technique [0002] In recent years, the open effect of furniture has become more and more popular in the domestic furniture market, because it can make the texture of various woods colorful, outstanding and natural. Especially precious wood, the effect of opening is better than that of closing. The open effect of furniture does not need to worry about the subsidence of the paint film, and it does not need to be used as a sealing primer. Direct spraying of an open primer and a top coat is enough, the process is simple, the production efficiency is improved, and at the same time, the various textures of the wood itself are not lost, and the three-dimensional effect of the paint film is increased. At present, after the construction of many domestic open paints, the residual smell is very strong aft...
