Mold-proof heat preservation coating for walls and preparation method of coating

Abstract

The invention discloses a mold-proof heat preservation coating for walls and a preparation method of the coating. The coating is prepared from, by weight, 15-20 kg of epoxy resin, 10-15 kg of high bauxite chamotte, 5-10 kg of ammonium dihydrogen phosphate, 10-15 kg of aluminum silicate fibers, 5-10 kg of dibutyl phthalate, 5-10 kg of magnesium silicate, 5-10 kg of lanthanum oxide, 5-10 kg of diatomite, 15-20 kg of sodium carboxymethylcellulose and 800-1,000 kg of water. The preparation method specifically includes the following steps of weighing and obtaining raw materials according to each proportion at first, pouring water into a reaction still, conducting heating to 30-40 DEG C, adding the epoxy resin, the high bauxite chamotte, ammonium dihydrogen phosphate, the aluminum silicate fibers, dibutyl phthalate, magnesium silicate, lanthanum oxide, the diatomite and sodium carboxymethylcellulose for stirring, raising the temperature to 90 DEG C, preserving the heat for 30 min, and then obtaining a finished product. The coating has the advantages of being free of toxin, smell, corrosion and pollution to the environment, great in sealing performance, high in strength and free of cracks.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a thermal insulation coating suitable for building thermal insulation instruments and a preparation method. Background technique [0002] The current energy-saving and thermal insulation measures for buildings are only aimed at the outer enclosure structure of the building. Generally, no thermal insulation measures are adopted between the partition walls of the houses in the building. In this way, different houses may have different temperatures, resulting in thermal pressure, and rooms with high temperatures will be The phenomenon of heat loss occurs, that is, heat flows from a room with a higher temperature to a room with a lower temperature. This unfair phenomenon of heat use is likely to cause various problems and contradictions. For example, the heat loss in the household is serious, which makes the heat use uneven among neighbors, resulting in unfair phenomena, and has high building...

[0002] The current energy-saving and thermal insulation measures for buildings are only aimed at the outer enclosure structure of the building. Generally, no thermal insulation measures are adopted between the partition walls of the houses in the building. In this way, different houses may have different temperatures, resulting in thermal pressure, and rooms with high temperatures will be Heat loss occurs, where heat flows from a warmer room to a cooler room

This unfair phenomenon of heat use is likely to cause various problems and contradictions. For example, the heat loss in the household is serious, which makes the heat use uneven among neighbors, resulting in unfair phenomena, and has high building energy consumption, thus Influenced the promotion of my country's building energy conservation policy
