Abstract

The invention discloses an antibacterial and waterproof coating applied to the outer wall of a bath room and a preparation method of the coating. The antibacterial and waterproof coating contains a component A and a component B, wherein the component A is prepared by the steps of washing shells, grinding, calcining to obtain shell powder, mixing the shell powder with Zn(NO3)2.6H2O, Na2CO3 and NaOH, carrying out suction filtration, washing and drying, and calcining; and the component B is prepared by the steps of heating polypropylene carbonate polyol, N,N-dimethylformamide and hexamethylene diisocyanate, stirring for reaction so as to obtain a prepolymer, adding 1,4-butanediol and stannous octoate into the prepolymer, adding deionized water, uniformly stirring and mixing. The antibacterialand waterproof coating has the characteristics that a manufacturing process is detailed and easy to implement, and the coating has a durable effect and a good antibacterial property and is capable ofresisting water logging.

Description

technical field [0001] The invention relates to the field of environmentally friendly coatings, in particular to an antibacterial and waterproof coating applied to bathroom exterior walls and a preparation method thereof. Background technique [0002] my country has a vast sea area and is a big country for marine aquaculture. With the rapid development of marine shellfish farming, the output of shellfish is increasing year by year. Although the increase in shellfish production has improved the economic income of fishermen, it has also produced a large number of " Shell litter". These discarded shells are often discarded at garbage dumps or seasides without treatment, occupying a large amount of land resources. When the amount of accumulation increases day by day, it is easy to cause a large number of various biological pathogens to breed, and also produce various foul smells, pollution. air, thereby deteriorating the marine shellfish farming environment. Shell is an inorgan...
