High-strength and corrosion-resisting novel building exterior wall paint with worm expelling function and preparation process thereof

Abstract

The invention discloses high-strength and corrosion-resisting novel building exterior wall paint with a worm expelling function. The high-strength and corrosion-resisting novel building exterior wall paint is prepared from the following components in parts by weight: 8 to 15 parts of pearl powder, 10 to 15 parts of nano titanium dioxide powder, 3 to 10 parts of cyclodextrin, 3 to 8 parts of acrylic resin, 0.2 to 0.4 part of chitin, 1 to 5 parts of fibrous wollastonite powder, 7 to 15 parts of glass fibers, 0.1 to 0.8 part of fluorescent powder, 1 to 3 parts of Chinese herbal medicine dry powder with the worm expelling function, 0.2 to 2 parts of carbon nanotubes, 1 to 3 parts of ceramic powder, 5 to 7 parts of wax and the balance of water. The exterior wall paint disclosed by the invention has high strength and good corrosion-resisting performance. The herbal medicine dry powder with the worm expelling function is arranged so that mosquitoes can be expelled and the mosquitoes are prevented from getting close to a building, so that the probability that the mosquitos, such as the mosquitos and flies, enter a room is reduced; and furthermore, the probability that the flies attach on an exterior wall is also reduced, so that the probability that the exterior wall is polluted by the flies is reduced.

Description

technical field [0001] The invention relates to a building exterior wall coating, in particular to a novel building exterior wall coating with high strength, corrosion resistance and insect repelling function and a preparation process thereof. Background technique [0002] Exterior wall paint is used to paint the exterior walls of buildings, so the most important indicator is anti-ultraviolet radiation, which requires long-term exposure without discoloration. Since 2013, energy-saving and environmentally friendly liquid stone water-based coatings have attracted more and more attention. Some exterior wall coatings also require water resistance and self-cleaning properties. The paint film should be hard and smooth, and the dirt will fall off as soon as it is washed. Exterior wall paint can be used for interior wall painting because it also has water resistance; while interior wall paint does not have anti-sun function, so interior wall paint cannot be used as exterior wall p...

Problems solved by technology

[0003] Existing exterior wall coatings do not have the function of repelling insects, especially the function of repelling mosquitoes, and this problem needs to be solved urgently
