Exterior wall thermal insulation coating material and preparation method thereof

Abstract

The invention belongs to the field of building materials, and particularly relates to an exterior wall thermal insulation coating material and a preparation method thereof, wherein the exterior wall thermal insulation coating material is mainly produced from the following raw materials by weight: polyvinyl formal, tassel tree fruit oil, quercus dentata thunb leaf, sapium sebiferum oil, hibiscus syriacus linn, ethyl hydroxybenzoate, aluminium glycinate, methyl methacrylate, phenoxyethanol and pistacia weinmannifolia oil. According to the present invention, the exterior wall thermal insulation coating material is added with the antibacterial materials such as hibiscus syriacus linn, quercus dentata thunb leaf, phenoxyethanol, pistacia weinmannifolia oil, tassel tree fruit oil and sapium sebiferum oil, and is added the floor protection material such as methyl methacrylate, aluminium glycinate, ethyl hydroxybenzoate and polyvinyl formal, such that the exterior wall thermal insulation coating material can improve the stain resistance of wooden floors, reduce the bacterial growth of wooden floors, achieve the convenient installation and use of wood floors, maintain the original color ofwood floors, and prolonging the service life of wood floors when the exterior wall thermal insulation coating material is used for wood floors.

Description

【Technical field】 [0001] The invention belongs to the field of building materials, and in particular relates to an external wall thermal insulation coating and a preparation method thereof. 【Background technique】 [0002] In recent years, with the improvement of people's living standards and the continuous development of society, people pay more and more attention to the choice of architectural decorative coatings, and the simpler the construction requirements of coatings, the better. Especially in exterior wall coatings, it has not only stayed in In terms of the most basic protection of the substrate, higher requirements are put forward for the decorative effect of the coating, and the exterior wall coating requires thermal insulation properties. [0003] However, at present, the thermal insulation coatings in the domestic market have shortcomings such as low gloss, poor adhesion, porous structure, easy to absorb moisture, easy to fall off, bulging, etc., and easy to stick ...

AI Technical Summary

Problems solved by technology

[0003] However, at present, the thermal insulation coatings in the domestic market have disadvantages such as low gloss, poor adhesion, porous structure, easy moisture absorption, easy peeling, and swelling, and are easy to stick back at high temperatures and brittle at low temperatures, resulting in easy cracking and peeling of the coating. It 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 service life of the building.
