Heat-insulating self-cleaning architectural coating and preparation method thereof

Abstract

The invention discloses a heat-insulating self-cleaning architectural coating, which is characterized by being prepared from the following raw materials in parts by weight: 30-40 parts of a bisphenol epoxy resin, 20-30 parts of a nano silicon resin, 3-4 parts of 2,2,4-Trimethyl-1,3-pentanediol monoisobutyrate, 0.5-1.0 part of aluminium oxide, 1-2 parts of glyceryl tristearate, 3-5 parts of polytetrafluoroethylene powder, 1-2 parts of shell-lac, 2-3 parts of polyethylene wax, 3-4 parts of fly ash floating beads, 0.3-0.4 part of azodiisobutyronitrile, 0.2-0.4 part of polyether modified siloxane, 1-2 parts of zinc naphthenate, 1-3 parts of polymerized silica, 6-9 parts of self-cleaning slurry, 1-2 parts of aminopropyltriethoxysilane, 10-13 parts of ethyl acetate, and 5-7 parts of ethylene glycol. The coating disclosed by the invention is used for solving the problem that a coat is poor in fouling resistance, easily polluted, and not ideal enough in heat insulation effect. The added fly ash floating beads are good in heat insulation effect and low in cost, and the added self-cleaning slurry has a good self-cleaning effect; the coating disclosed by the invention is high in adhesion and good in abrasion resistance, and has excellent heat insulation and self-cleaning functions; and the coating is low in production cost, simple in operation and wide in application range.

Description

technical field [0001] The invention relates to a coating and a preparation method thereof, in particular to a heat-insulating self-cleaning architectural coating and a preparation method thereof. Background technique [0002] Coating is a material that can be coated on the surface of an object by different construction techniques to form a solid film with strong adhesion, certain strength and continuity. The film formed in this way is commonly called a coating film, also known as a paint film or a coating. It belongs to organic chemical polymer materials, and the formed coating film belongs to the type of polymer compounds. There are many ways to decorate and protect buildings, but the use of coatings is one of the simplest, most economical, and convenient for maintenance and renewal, so it is widely used in construction projects at home and abroad. However, traditional coatings will change color and fall off after a period of time, and glass curtain walls or tile veneers...

Problems solved by technology

However, the traditional paint will change color and fall off after a period of time, and the glass curtain wall or tile veneer will bring light pollution, increase the weight of the building, and pose safety hazards and other problems.
