Example Embodiment

[0016] Example one:

[0017] A comprehensive environmental protection shell powder paint, take 90kg of 325 mesh shell powder, 10kg of cyclodextrin inclusion compound, 10kg of barium sulfate, 10kg of chitosan, 0.5kg of hydroxypropyl methylcellulose HPMC, redispersible latex powder 0.4kg, 0.4kg of polyvinyl alcohol powder, 2kg of sodium bentonite and 0.3kg of wood fiber are put into a mixer and stirred for 25-30 minutes to obtain the finished product.

Example Embodiment

[0018] Embodiment two:

[0019] A comprehensive environmentally friendly shell powder coating, taking 95kg of 325 mesh shell powder, 15kg of cyclodextrin inclusion compound, 15kg of barium sulfate, 15kg of chitosan, 0.6kg of hydroxypropyl methylcellulose HPMC, and redispersible latex powder 0.8kg, 0.8kg of polyvinyl alcohol powder, 3kg of sodium bentonite and 0.2kg of wood fiber are put into a mixer and stirred for 25-30 minutes to obtain the finished product.

[0020] Chitosan (Chitosan), its special structure and strong reactive amine group (-NH2) can chemically react with many gaseous harmful substances, so it is effective for formaldehyde and TVOC (total organic release) that escape into the air. The amount), chitosan can capture and eliminate it, and finally achieve the purpose of purifying the air.

[0021] Chitosan is made from the chitin of shrimp and crab shells. Its structure is similar to polysaccharides. Its monomer structure is special. Multiple functional groups with h...

Abstract

The invention discloses a comprehensive environment-friendly shell powder coating.The comprehensive environment-friendly shell powder coating is prepared from, by weight, 90-95 parts of shell powder, 10-15 parts of cyclodextrin inclusion compound, 10-15 parts of barium sulfate, 10-15 parts of chitosan, 0.5-0.6 part of hydroxypropyl methyl cellulose HPMC, 0.4-0.8 part of redispersible latex powder, 0.4-0.8 part of polyvinyl alcohol powder, 2-3 parts of sodium bentonite and 0.2-0.3 part of wood fibers.The fineness of the shell powder is at least 325 mesh.The coating is environmentally friendly, the adopted raw materials are dry powder, most of the raw materials are inorganic materials easy to obtain and can be recycled, a waterproof and stain-resistant effect can be achieved without painting of latex paint, the situation that an organic solvent volatilizes to the atmosphere to cause pollution is avoided, and the harm of the coating to human health in the production, transportation, storage and construction processes is eliminated.No toxic or harmful matter exists in the coating, the home environment can be effectively improved, and the content of the toxic and harmful matter, such as formaldehyde, in households is reduced.

Description

technical field [0001] The invention relates to chemical materials, in particular to a comprehensive environmental protection shell powder coating. Background technique [0002] Most of the current architectural coatings are organic coatings with synthetic resin as the main film-forming substance. The raw material of synthetic resin mainly comes from petroleum, and petroleum is a kind of non-renewable resource. In addition, a certain amount of organic solvents are used in the manufacture and construction of organic coatings. These organic solvents also come from petroleum, and these organic solvents will be directly discharged into the atmosphere during the production and construction of coatings, which causes resource pollution. A large amount of waste will cause direct or indirect harm to the environment and human body. [0003] Shell powder is made by calcining and crushing natural and artificially cultivated shells at high temperature. Different from artificially synt...
