Abstract

The invention relates to a light-weight high-strength anti-condensation dry powder coating and a preparation method thereof. The light-weight high-strength anti-condensation dry powder coating comprises the following components in parts by weight: 15-25 parts of calcium silicate board sanding waste, 15-25 parts of food-grade ash calcium powder, 3-5 parts of special-grade white cement and 3-5 partsof an anion carrier material. Compared with the prior art, a large amount of sanding waste powder in the calcium silicate board industry is used, the negative ion carrier material is added, and the product has the advantages of being environmentally friendly, low in cost, light in weight, high in strength, good in anti-condensation performance, capable of releasing negative ions and purifying airand the like.

Description

technical field [0001] The invention relates to the technical field of dry powder coatings, in particular to a lightweight high-strength anti-condensation dry powder coating and a preparation method thereof. Background technique [0002] With the development and progress of society and modern science and technology, people are paying more and more attention to the impact of the living environment on health, and the calls for low or even zero emissions of volatile organic compounds (VOC) in paints are getting louder and louder. Dry powder coating is non-toxic and tasteless, does not contain harmful substances such as formaldehyde, does not produce bacteria, and does not endanger human health. It is a green and environmentally friendly coating. [0003] Invention patent CN201610605450.2 discloses a diatom ooze negative ion dry powder coating, which is composed of the following mass percentages: ash calcium powder 22.8% to 28.9%, diatom ooze 12.2% to 14.2%, Negative ion additi...
