Abstract

The invention relates to an ecological and environment-friendly coating for straw and a preparation method thereof. The coating comprises the following components in parts by weight: 20 to 25 parts ofan emulsion, 5 to 10 parts of natural colored sand, 2 to 3 parts of rubber powder, 0.2 to 0.5 part of cellulose ether, 0.6 to 1.5 parts of diatomite, 0.1 to 0.6 part of a mold-proof antibacterial agent, 2 to 4 parts of a coalescing agent, 2 to 4 parts of a dispersing agent, 4 to 5 parts of a defoaming agent, 2 to 3 parts of a thickener, 10 to 15 parts of deionized water, 4 to 5 parts of wood pulp, 0.5 to 0.7 parts of straw stalk with the length of 0.1 to 0.5 cm, 0.7 to 0.9 part of straw stalk with the length of 0.5 to 1 cm, and 0.8 to 1 part of straw stalk with the length of 1 to 1.5 cm. Compared with the prior art, after the coating is used, a more vivid bumpy texture can be created, and the coating has anti-cracking and heat insulation performances, has an archaistic ecological decoration performance, has the functions of humidifying, decomposing formaldehyde, killing bacteria and removing odor and preventing corrosion and mold, and is beneficial for improving indoor environment.

Description

technical field [0001] The invention relates to a coating, in particular to a straw ecological and environmental protection coating and a preparation method thereof. Background technique [0002] After the grain harvest, pieces of straw were burned on the spot. Burning rice straw not only pollutes the air environment, destroys the ecology, changes the soil structure, but also is not conducive to energy conservation and the development of circular economy. In daily life, wall paint is one of the main decorative materials used for wall decoration in decoration, especially the final coating in painting, which has decorative and protective functions. The current wall paint has the disadvantages of single function and insufficient environmental protection. [0003] With the continuous improvement of people's quality of life, people's understanding of coatings has also been continuously improved. In recent years, space transformation, homestays have developed rapidly, and retro ...
