Abstract

The invention discloses a high-solid-content aliphatic acrylic polyurethane paint and a preparation method thereof. The high-solid-content aliphatic acrylic polyurethane paint comprises a component A, a component B and a component C, wherein the component A is prepared in the following steps: (1) preparing a 20% polyamide wax pulp aid; (2) preparing grinding color paste from the following components: high-solid low-viscosity hydroxy acrylic resin, a wetting agent, a dispersing agent, triethoxy ethyl propionate, titanium dioxide, spherical glass beads, carbon black, 154L yellow, bentonite and dimethylbenzene; (3) paint mixing: adding an ultraviolet light absorber, the 20% polyamide wax pulp aid, the flatting agent, a defoaming agent and n-butyl acetate, so as to obtain the component A; the component B is prepared from aliphatic isocyanate tripolymer; the component C is prepared by uniformly mixing n-butyl acetate, PMA and S-100. The high-solid-content aliphatic acrylic polyurethane paint is environmentally friendly, the energy is saved, and the emission of poisonous and harmful gas is greatly reduced, so that the energy saving and the consumption reduction are achieved; the coating period is short, and the efficiency is high; a once coated dry membrane is high in thickness, the coating frequency is reduced, the coating efficiency is improved, the labor intensity is alleviated, and a film is strong in impact resistance.

Description

technical field [0001] The invention relates to the technical field of organic polymer synthetic materials, in particular to a high-solid aliphatic acrylic polyurethane coating suitable for steel structures and concrete protection in various atmospheric environments and a preparation method thereof. Background technique [0002] The emission of volatile organic compounds (VOC) in coatings is the main source of environmental pollution from coatings. According to statistics, millions of tons of solvents are discharged from coatings into the atmosphere every year around the world. These VOCs not only destroy the environment that human beings rely on for survival Atmospheric ecological environment, but also cause harm to human health. Environmentally friendly coatings have become one of the key development directions of the industry, which mainly include high-solid coatings, water-based coatings, powder coatings, UV coatings, etc., and high-solid coatings are among the varieties...
