Comprehensive environment-friendly shell powder coating

Abstract

本发明公开了一种综合性环保贝壳粉涂料,按重量计包括:贝壳粉90~95份、环糊精包合物10~15份、硫酸钡10~15份、几丁聚醣10~15份、羟丙基甲基纤维素HPMC0.5~0.6份、可再分散乳胶粉0.4~0.8份、聚乙烯醇粉0.4~0.8份、钠基膨润土2~3份和木质纤维0.2~0.3份;所述贝壳粉的细度都至少为325目。本发明环保,所用原料都是干粉,大部分是易得的无机材料,可以循环利用,而且不用涂刷乳胶漆,就可达到防水耐污效果,避免了有机溶剂挥发到大气中造成污染,消除了涂料在生产、运输、储存和施工过程中对人体健康的危害;且涂料中无有毒有害物质,能有效提升家居环境,减少家庭中甲醛等有毒有害物质的含量。
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.
