[0034] Preparation of silicone modified acrylic resin:

[0035] Mix vinyltrimethylsilane and methyl acrylate at a mass ratio of 1:3 and put them into a reactor to obtain a mixture, then add 1% sodium lauryl sulfate and 0.5% of the mixture to the reactor. Potassium persulfate and water of the same quality as the mixture were stirred and reacted at 50°C for 2 hours, and then discharged to obtain a silicone-modified acrylic resin;

[0036] Preparation of exterior wall dustproof coating:

[0037] (1) In parts by weight, weigh 60 parts of the above silicone-modified acrylic resin, 15 parts of spare self-made dustproof filler, 5 parts of calcium chloride, 1 part of polyether modified polyorganosiloxane and 20 parts After the water is mixed, put it into a colloid mill, grind and mix it for 20 minutes at a speed of 2000r / min to obtain a dust-proof coating;

[0038] (2) Apply the dust-proof paint obtained above on the surface of the exterior wall, and control the thickness of the coa...

Abstract

The invention relates to a preparation method of an external wall dustproof coating, and belongs to the technical field of external wall coatings. The preparation method disclosed by the invention comprises the steps as follows: firstly, using malvaceae pollen with a micron-sized particle size as a raw material, and performing a reaction on the malvaceae pollen and 3,4-dihydroxyphenylalanine underthe action of catechol oxidase to obtain reaction filter residues; then performing a reaction on the reaction filter residues and a mixed saline solution of iron salt and sodium bicarbonate to obtaina self-made dustproof filler; then using organic silicon modified acrylic resin as a paint base stock; and finally, mixing the self-made dustproof filler with the organic silicon modified acrylic resin as well as other auxiliary materials to prepare paint, then brushing the paint on a wall surface, applying magnetic field processing to the brushed paint, and finally, naturally curing to form theexternal wall dustproof coating. The dustproof coating prepared with the preparation method disclosed by the invention is very excellent in dustproof effect; and as time goes by, a double-micro-synaptic-junction structure is generated on the surface of the coating, and thus, a contact angle is further increased, the dustproof effect is very excellent, and the coating has a wide application prospect.

Description

technical field [0001] The invention relates to a preparation method of an exterior wall dustproof coating, which belongs to the technical field of exterior wall coatings. Background technique [0002] Paint is a supporting engineering material that is coated on the surface of a solid material (to be protected and decorated) and can form a continuous film that adheres firmly. In ancient times, paints were made of oil and natural resins, so they were called "paints". With the development of science and technology, many synthetic resins were widely used as raw materials for paints, which fundamentally changed the appearance of paint products. , its correct name should be changed to "organic coating", referred to as coating. [0003] As early as the 1960s, there were a small number of documents and patents about low surface energy non-toxic antifouling coatings. Low surface energy vulcanized rubber was used as antifouling coatings, but toxins were added therein. The research ...
