Abstract

The invention discloses an environment-friendly building water-based paint, which is prepared from the following raw materials in parts by weight: 60 to 70 parts of a silicone acrylic emulsion, 8 to 10 parts of perfluorosiloxane resin, 6 to 9 parts of a composite filler, 1 to 1.4 parts of a coupling agent, 2 to 3 parts of a mildew-proof compound, 2 to 3 parts of hydroxyethyl cellulose, 0.9 to 1 part of an auxiliary agent and 30 to 40 parts of pure water. The invention also discloses a preparation method of the water-based paint. According to the invention, the silicone acrylic emulsion and theperfluorosiloxane resin are used as basic film-forming substances of the paint, and water is used as a solvent, so that the use of an organic solvent is avoided, the environmental protection requirement is met, and the silicone acrylic emulsion and the perfluorosiloxane resin are compounded for use, so that the paint has good waterproof performance; the self-made mildew-proof compound is added into the paint, so that the durability of the mildew-proof and antibacterial effects is improved; the water-based paint prepared by the invention has good waterproof performance and lasting mildew-proofand antibacterial effects, is applicable to building exterior walls, and can play an effective protection role.

Description

technical field [0001] The invention belongs to the technical field of water-based paints, and in particular relates to an environment-friendly water-based paint for buildings and a preparation method thereof. Background technique [0002] Solvent-based coatings are an important source of VOC, which cause great pollution to the environment and great harm to the human body. At the same time, there are safety hazards such as flammability and explosion in construction, storage, and transportation. Water-based paint has the characteristics of green, energy saving, safety and convenient function, and has been developed rapidly in all countries in the world. Building exterior wall coatings can beautify the environment and the living room, but due to the poor scrub resistance of traditional coatings, the coating will change color and fall off after a short period of time, and the glass curtain wall or tile veneer will bring light pollution, increase the weight of the building, and ...
