Abstract

The invention discloses a moisture-proof paint and a preparation method thereof. The paint comprises the following components: an epoxy resin, propylene glycol polyoxypropylene ether, chlorinated paraffin, barium sulfate, silica sol, bentonite, stearic acid, polyacrylamide, an ethylene-vinyl acetate copolymer, a plasticizer, a defoaming agent, a surfactant and a solvent. The preparation method comprises the following steps: putting the epoxy resin, chlorinated paraffin, barium sulfate and bentonite in a stirrer, and performing stirring and mixing to obtain a mixture 1; putting the mixture 1 into a reaction kettle, adding the polyacrylamide, defoaming agent, ethylene-vinyl acetate copolymer and plasticizer, performing heating under inert gas protective conditions and performing holding for some time to obtain a mixture 2; and finally, adding the propylene glycol polyoxypropylene ether, silica sol, stearic acid, surfactant and solvent into the mixture 2, and performing mixing to obtain the moisture-proof paint. The moisture-proof paint disclosed by the invention has favorable adsorbability and moisture proofness.

Description

Technical field [0001] The invention belongs to the technical field of paint preparation, and specifically relates to a moisture-proof paint and a preparation method thereof. Background technique [0002] Mold is caused by high humidity in the air. Scientific research shows that when the temperature of the home environment is between 25°C and 30°C and the relative humidity exceeds 60%RH, the oxygen in the air is sufficient, and the mold will be extremely active at this time and will multiply rapidly. Therefore, during the rainy season every year, the troubles caused by mold will erode people's lives extensively. In tropical, subtropical, and temperate regions, especially coastal regions, the mold problem caused by humidity has plagued people's lives all year round. According to statistics, the global economic loss caused by humidity and mildew is as high as hundreds of billions of dollars each year. Humidity prevention in the home has always been a concern in daily life, and s...
