Carbon dioxide bio-based interior wall coating and preparation method thereof

The invention discloses a carbon dioxide bio-based interior wall coating and a preparation method thereof. The carbon dioxide bio-based interior wall coating is prepared from the following components in parts by weight: 10 to 18 parts of solvent, 10 to 25 parts of carbon dioxide-based waterborne polyurethane resin, 20 to 25 parts of bio-based acrylic emulsion, 2 to 5 parts of nano titanium dioxide, 3 to 6 parts of diatomite, 0.3 to 1.0 part of wetting agent, 0.5 to 1.2 parts of dispersing agent, 0.3 to 1.3 parts of defoaming agent, 0.4 to 0.6 part of hydroxyethyl cellulose and 1.0 to 2.2 parts of coalescing agent. 0.4-1.0 part of an anti-freezing aid, 0.2-0.8 part of a flatting agent, 15-23 parts of a pigment and 10-18 parts of a filler; the content of carbon-14 reaches 25 wt% or above, and application of petrochemical materials and emission of carbon dioxide are effectively reduced. 本发明公开了一种二氧化碳生物基内墙涂料及其制备方法，二氧化碳生物基内墙涂料包括按照重量份数计的如下组分：溶剂10-18份、二氧化碳基水性聚氨酯树脂10-25份、生物基丙烯酸乳液20-25份、纳米二氧化钛2-5份、硅藻土3-6份、润湿剂0.3-1.0份、分
