Preparation method of external wall dustproof coating

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 ...

Problems solved by technology

[0007] The main technical problem to be solved by the present invention is to provide a dust-proof coating for exterior walls in view of the defects that the currently commonly used exterior wall coatings are acrylic resin coatings, which are easy to stick to dust, have poor pollution resistance, and affect the decorative effect and use value.
