Abstract

The invention relates to a cold-resistant coating for outdoor facilities and a preparation method thereof. The coating contains the following components in parts by mass: 16-30 parts of styrene-butadiene latex, 5-13 parts of styrene-butadiene rubber, and liquid coumarone resin 1.2-2.8 parts, 3-8 parts of acrylic acid, 0.2-0.5 parts of N,N-diethylthiourea, 25-35 parts of silicon dioxide, 17-25 parts of wollastonite, 1-2.5 parts of carbon black, triphosphate 0.03-0.05 parts of butyl ester, 0.2-0.5 parts of stearic acid, 0.3-0.7 parts of polyethylene glycol, 2-3.5 parts of acetone, and 50-65 parts of water. The cold-resistant paint for outdoor facilities provided by the present invention has a paint film that can withstand stone impact of 30kg at a low temperature of -30°C, and has a hydrochloric acid corrosion resistance time of ≥1100h, and has good aging resistance and wear resistance, and the paint film can maintain the original luster for a long time. Change.

Description

technical field [0001] The invention relates to a paint for outdoor use and a preparation method thereof, in particular to a cold-resistant paint for outdoor facilities and a preparation method thereof. Background technique [0002] The outdoor facilities are exposed to the outdoors and have to withstand wind, sun, rain all year round, and the surface paint film is easily damaged. Moreover, the frequency of use of outdoor facilities is high, and the surface paint film is easily worn, which affects the appearance and use of outdoor facilities. When the temperature is low in winter, the paint film on the surface of the facility is easy to freeze, crack and fade, thus losing its original luster. Once the paint film falls off, the internal steel materials will be exposed to the air, rusting and other phenomena will occur, and the outdoor facilities cannot be used normally, resulting in waste of resources and economic losses. Contents of the invention [0003] Technical probl...
