Embodiment Construction
[0017] In order to fully understand the technical content of the present invention, the technical solution of the present invention will be further introduced and illustrated below in conjunction with specific embodiments.
[0018] The preparation method of antiskid anticorrosion polyurea coating is as follows:
[0019] (1) Add aliphatic polyisocyanate trimer and xylene into the mixing tank, and disperse at a stirring speed of 300-500r / min for more than 20 minutes to obtain component A;
[0020] (2) Add the modified dimeric aspartic acid ester polyurea resin, xylene and propylene glycol methyl ether acetate with NH equivalent of 900-1200 and viscosity of 800-1500mPa·s into the mixing tank at 300-500r Start stirring at a stirring speed of / min, then add dispersant, leveling agent, defoamer and fumed silica to the mixing tank in turn, stir for 10 minutes, then add pigments to the mixing tank, and stir for more than 30 minutes until the mixture fineness≦ 40 μm, then continue to ...

Abstract
The invention belongs to the technical field of coating production, and particularly relates to an antiskid and antiseptic polyurea coating as well as a preparation method and an application method thereof. The antiskid and antiseptic polyurea coating comprises a component A of which the essential component is aliphatic series polyisocyanate trimer and a component B of which the essential component is modified dimerization type asparaginic acid ester polyurea resin, wherein the component A and the component B are packaged respectively and independently, and are uniformly mixed for coating. According to the invention, polymer particles are added into the coating, so that a formed coating layer is excellent in antiskid effect and has certain elasticity, and conforms to human engineering; layering and sedimentation are avoided during the storing process; besides, the curing speed of the coating is moderate, the viscosity is lower, the wettability of the polyurea coating is improved, the construction time of the polyurea coating is prolonged, the polyurea coating can be used in a roll coating, brush coating or spray coating manner, the construction is facilitated, and specialized polyurea spraying equipment and professional constructors are not needed; the polyurea coating has excellent water resistance and disinfectant chemical corrosion resistance, and can be soaked in water for a long time.
Description
technical field [0001] The invention relates to the technical field of paint production, in particular to an anti-skid and anti-corrosion polyurea paint that is easy to construct and a preparation method and application method thereof. Background technique [0002] With the rapid development of the national economy, people's living standards and consumption levels are getting higher and higher. As a kind of water theme park integrating leisure, entertainment, summer vacation and fitness, it has also emerged as the times require. Since the construction of Hong Kong Ocean Park, the first water theme park in Asia, in the past two decades, especially in the past ten years, a large number of new water theme parks have been built in China. The water park is exposed to the outdoors. Except for a few months during the closing period, the water park is in an underwater or alternately wet and dry environment for a long time. The ground of the early water parks was not protected by pa...
