Problems solved by technology

However, since the coating film of architectural latex coatings is not as dense as that of solvent-based architectural coatings, it is easily corroded by bacteria and microorganisms and mildew spots appear, which not only affects the appearance of buildings, but also brings harm to human health.
[0004] In addition, most of the current buildings are made of glass, wood products, paper products, paint and other materials. These materials have poor water absorption. In the southern region with high humidity, a large amount of water vapor will cause fogging, which will induce a large number of molds. to grow

Embodiment 1

[0034] Embodiment 1, prepare the building material according to the ratio in the table below.

[0035]

[0036] Use this building material to make a coating, and perform functional tests respectively:

[0037] 1. Hygroscopicity: Make a coating sample with a thickness of 2mm-3mm. After the prepared sample was dried naturally for 24 hours, it was dried in a drying oven at 80°C for 5 hours. Then place it in a humidity-conditioning box to carry out a moisture absorption test, and the test conditions are a temperature of 25° C. and a relative humidity of 85%. After 48 hours, take it out and weigh it. Through the calculation of the mass before and after the test, it is concluded that the moisture absorption of the sample reaches 300g / m 2 , indicating that the test coating has moisture absorption function; put the moisture-absorbing sample into a humidity-conditioning box with a temperature of 25°C and a relative humidity of 35%, take it out and weigh it after 48 hours, and obta...

Embodiment 2

[0040] Embodiment 2, prepare the building material according to the ratio in the table below.

[0041]

[0042] The same method used in Example 1 was used for functional testing, and the results showed that the coating made of this coating was tested in a humidity control box. Under the conditions of a temperature of 25°C and a relative humidity of 85%, the moisture absorption reached 320g / m 2 ;Under the conditions of temperature 25℃ and relative humidity 35%, the moisture release can reach 260g / m 2 , has good moisture absorption and desorption functions; the coating’s killing rate against six comprehensive molds of Candida albicans and Aspergillus niger has reached level 0; the killing rate against Staphylococcus aureus and Escherichia coli are respectively: 99.9% and 99.9%; the thermal conductivity of the coating measured by the coating thermal conductivity tester is 0.035W / m·K.
