Problems solved by technology

[0002] The paint made of hydrated lime (calcium hydroxide) has appeared as a rough self-adjusting and self-use non-commercial paint, but this paint cannot meet the commercial function of architectural decoration like latex paint, that is: paint It is difficult to brush evenly, the surface is rough, there are obvious traces of the roller brush interface, the covering power is not enough, and it is easy to peel when combined with the base layer
[0003] And the latex paint that uses acrylic emulsion as a film-former also has its fatal weaknesses as the architectural decorative coatings that are widely used now, such as: it will soften and whiten when it is soaked in water, and it is easy to powder; the organic and harmful volatile content of acrylic emulsion is high. , has great pollution to the environment; after painting, there will be small orange peels pulled up by rollers on the surface, which will affect the hand feel; it will not be durable due to oxidation and hydrolysis; it needs to add preservatives to prevent corrosion, and preservatives will endanger human health
