Problems solved by technology

However, because the gelation time of polyurea reaction is very short, only a few seconds, the traditional spray polyurea coating construction must use special high temperature and high pressure impact mixing equipment, which not only increases the construction cost, but also is not conducive to the safety of general construction personnel. operate
A series of problems have also been exposed during the application process, such as easy formation of pitting and orange peel on the surface of the coating, resulting in poor appearance; poor wettability to the substrate and low adhesion; concentrated reaction exotherm, heat Large shrinkage rate, large internal stress; poor color retention and UV resistance, etc.

Abstract

The invention discloses a terrace coating and a preparation method thereof. The terrace coating consists of a first component and a second component, wherein the first component comprises the following ingredients in percentage by weight: 25 to 40 percent of polyaspartic acid ester resin, 5 to 10 percent of hydroxy acrylic resin, 0.2 to 0.5 percent of dispersing agent, 3 to 10 percent of anti-wear additive, 10 to 15 percent of rustproofing pigment, 20 to 40 percent of pigment and filler, 0.2 to 0.5 percent of antifoaming agent, 0.2 to 0.5 percent of leveling agent and 5 to 10 percent of solvent. The preparation method comprises the steps of weighing the components according to a formula, preparing the first component and packaging. According to the terrace coating disclosed by the invention, slurry has long gelation time; a film layer has a good mechanical performance; and the terrace coating is wear-resistant, weather-resistant, anti-corrosive and waterproof.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a floor coating and a preparation method thereof. Background technique [0002] Polyurea is a new type of green material developed abroad in the past ten years to meet the needs of environmental protection. It is an elastomeric substance formed by the reaction of isocyanate components and amino compound components. It is constructed with special equipment and has a solid content of 100%, solvent-free and pollution-free. It is another major technological advancement after high-solid coatings, water-based coatings, and powder coatings. It has changed the common shortcomings of solvent pollution, thin thickness, sagging, and long curing time in traditional processes, and is especially suitable for on-site spraying. However, because the gelation time of polyurea reaction is very short, only a few seconds, the traditional spray polyurea coating construction must use special high temperature a...
