Problems solved by technology

However, nano-titanium dioxide needs to be catalyzed by ultraviolet light to decompose formaldehyde well. However, the intensity of ultraviolet rays is often not enough in the room, so the ability of nano-titanium dioxide to decompose formaldehyde is greatly weakened.

Embodiment 1-4

[0074] Embodiment 1-4 Preparation of the wall coating composition of the present invention

[0075] Using the preparation method of the present invention, the wall coating composition of the present invention is prepared according to the components described in Table 1 and their weight percentages. The preparation method comprises: pulverizing each component according to particle size requirements, sieving, mixing evenly, and packaging. According to the requirements of fineness, corresponding crushing and sieving are carried out, and the components that do not meet the fineness are recovered and crushed and sieved again, and all the components that meet the fineness are mixed for many times. When the components are mixed evenly Finally, weigh and pack, and the finished product is placed in a dry place.

Abstract

The invention provides a wall coating composition, a preparation method and an application of the wall coating composition, and a wall coating containing the wall coating composition. The wall coating composition provided by the invention comprises the following constituents in parts by weight: 12-20 parts of white carbon black, 20-45 parts of cement, 2-30 parts of quartz sand, 0.1-0.5 part of fibres, 1-15 parts of bentonite, 1-15 parts of attapulgite, 0.3-9 parts of nanometre titania, 3-15 parts of tourmaline, 0.3-8 parts of polyphenol extract, 0.1-5 parts of a humectant, 0.1-3 parts of an adhesive, 0.1-2 parts of a defoamer, 2-30 parts of kieselguhr, 3.5-30 parts of titanium dioxide and 0-6 parts of optional colouring pigments. Upon inspection, the wall coating composition provided by the invention overcomes the defect that the existing coatings contain calcium hydroxide, can be used for effectively adsorbing free formaldehyde, and releasing anions, a far infrared ray and a micro-current, and has a good application prospect.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular, the invention relates to a dry powder coating used for painting and decoration of building walls. Background technique [0002] Wall coatings are used for building walls and are the most widely used wall decoration materials. Among the paints used in buildings, wall paint is the part with the largest exposed area, so it has a great impact on human life and health as well as the environment. [0003] People nowadays advocate "low-carbon life". With the improvement of consumers' awareness of their own health and environmental protection, "low-carbon" life has become the general trend and the necessity of future development. Water-based wall coatings are undoubtedly related to low-carbon Carbon environmental protection is the closest wall paint product. Due to its superiority in environmental protection, water-based coatings have a market share of over 60% in Japan, Europe and the ...
