Abstract

The embodiment of the present invention discloses a heat-insulating, fire-proof and anti-corrosion coating and a preparation method thereof, comprising the following components by weight percentage: 26-40% of water-based chlorinated resin, 5-9% of nano-titanium dioxide, and 6-12% of vermiculite %, nano rector clay 1‑5%, calcium sulfate whisker 8‑20%, granular cotton 6‑12%, potassium octatitanate whisker 4‑8%, sepiolite 8‑15%, additive 0.3‑ 1.5%, modifier 0.7-2%, and the balance is water 10-15%. The present invention is used to utilize the copolymerization of high chlorine polymers to synthesize a new type of high water resistance, anti-corrosion and flame-retardant polymer material, which is combined with the almost full-spectrum reflection characteristics of inorganic salt whiskers to near-infrared rays, and is supplemented by mineral fibers. It has greatly improved the poor water resistance and durability of the heat-insulating coating, and has a variety of colors to choose from, which effectively solves the lack of performance of the existing commercially available coatings, and also has the functions of fire prevention, sound insulation, waterproof, and anti-corrosion.

Description

technical field [0001] The invention belongs to the technical field of paint preparation, and in particular relates to a heat-insulating fire-proof and anti-corrosion paint and a preparation method thereof. Background technique [0002] Most of the existing thermal insulation coatings on the market use styrene-acrylic resin or pure acrylic resin as the linking material, with hollow glass microspheres and ceramic microspheres as functional fillers, and reflective coatings composed of titanium dioxide as the reflective pigment. The main principle is to rely on The reflectivity of titanium dioxide and the blocking of heat conduction by hollow glass beads achieve the effect of cooling and saving energy. The thermal insulation coating made by the above method has the following defects. Because the molecular structure of styrene-acrylic and pure acrylic emulsion contains benzene rings and a large amount of emulsifier, there are certain defects in water resistance and weather resis...
