Abstract

The invention discloses a preparation method of a heatproof and thermal insulation paint. The method includes: weighing distilled water, zircon sand, iron manganese oxide, tetrafluoroethylene powder,lead powder, bentonite, heavy calcium carbonate powder, a water repellent sodium methylsiliconate, perlite, polyvinyl formal, carboxymethyl cellulose, spherical silica, titanate, limestone and perchloro-ethylene resin. The paint prepared by the method provided by the invention has the characteristics of simple preparation method, good thermal insulation effect, good weather resistance, no sheddingat a high temperature of 250-350DEG C, acid and alkali resistance, excellent moisture resistance, and short drying time. When the product forms a film, the product film has high strength, grade 1 adhesion, good corrosion resistance, no corrosion to walls, metals, woods and plastics, impact strength of 80-100J, hardness of 5H, no change after 3-7d in 30DEG C distilled water, electric insulation, good anti-mold properties, flexibility of 1mm, and good gloss. After 4-8d of soaking in a sodium chloride solution, the product film is free of blistering and cracking, the paint film is smooth, free of brushmark and coarse grain, and can be widely produced to replace existing materials.

Description

technical field [0001] The application belongs to the field of decorative materials, and in particular relates to a preparation method of a heat-resistant thermal insulation coating. Background technique [0002] Insulation materials are generally materials with a thermal coefficient less than or equal to 0.12. The development of thermal insulation materials is rapid, and the use of good thermal insulation technology and materials in industry and construction can often achieve twice the result with half the effort. Every ton of mineral wool insulation products used in buildings can save one ton of oil a year. [0003] R&D background: Traditional thermal insulation materials are mainly to increase the gas phase porosity and reduce the thermal conductivity and conductivity. In order to increase convective heat transfer and radiation heat transfer in the use environment, fiber-based thermal insulation materials must have a thicker coating; while profile-based inorganic ther...
