Problems solved by technology

[0002] In recent years, with the change of the environment, the cost of labor and the construction of buildings are getting higher and higher, resulting in more and more frequent cleaning of building exterior walls and more and more accidents; poor elasticity at room temperature, Poor wear resistance and other disadvantages, and high temperature is easy to stick back, low temperature is easy to be brittle, resulting in easy cracking and peeling of the inner wall, and rainwater is easy to penetrate into the wall and corrode the wall, which not only affects the decorative appearance of the building, but also reduces the quality of the building. In addition, the taste of indoor paint and its easy cracking and dirt resistance are big problems that plague people's lives. The main problem is that the existing antibacterial and antifouling materials are mainly made of organic materials. Organic materials and cement The strength of the bond between them is not enough to form a layered phenomenon

Embodiment 1

[0026] A construction method of an antibacterial and antifouling building, adopting the following steps:

[0027] (1) Preparation of antibacterial and antifouling layer: Take 40g of shell powder, 50g of magnesium oxide, and 200g of paraffin, stir well, then add 100g of silicone oil substituted with side chain amino groups, stir well; add 50g of film-forming aid before use;

[0028] (2) Preparation of paint: Mix 70g of polyvinyl alcohol, 320g of light calcium carbonate, 50g of talcum powder, and 40g of gypsum powder evenly, and add 500g of water to make a paint;

[0029] (3) On the inner wall of the house to be constructed, paint a layer of antibacterial and antifouling layer with a thickness of about 1-2mm and dry;

[0030] (4) Add the antibacterial and antifouling layer of step (1) to step (2), and stir evenly; on the dried wall surface of step (3), evenly smear the paint doped with antibacterial and antifouling layer, with a thickness of 1- 2cm, dry;

[0031] (5) On the wa...

Embodiment 2

[0033] A construction method of an antibacterial and antifouling building, adopting the following steps:

[0034] (1) Preparation of antibacterial and antifouling layer: Take 30g of shell powder, 70g of magnesium oxide, and 300g of paraffin, stir well, then add 150g of silicone oil substituted with side chain amino groups, stir well; add 70g of film-forming aid before use;

[0035] (2)-(5) as in Example 1.

Abstract

The invention relates to a construction method of an antibacterial and antifouling building, and belongs to the technical field of antibacterial and antifouling of building construction. The method comprises the following steps: taking 3-4 parts by weight of seashell powder, 5-7 parts by weight of magnesium oxide and 20-30 parts by weight of paraffin, performing uniform stirring, then adding 10-15parts by weight of side chain amino substituted silicone oil, and performing uniform stirring; and adding 5-7 parts by weight of a coalescing agent before use in order to prepare an antibacterial andantifouling layer. The side chain amino modified silicone oil, the seashell powder, the magnesium oxide and the like are added to improve the binding force with the cement wall surface, the super-hydrophobic property is realized by utilizing the super-strong surface tension, and dusts and the like are not prone to adhering to the cement wall surface.
