A kind of environment-friendly interior wall coating and preparation method thereof

Abstract

The invention discloses environment-friendly inner wall paint, which is prepared from the following ingredients in parts by weight: 35 to 45 parts of fluorine-containing triazine type film forming polymers, 10 to 15 parts of phosphoric acid modified nanometer titanium dioxide, 20 to 30 parts of pigment filling materials, 2 to 5 parts of anti-foaming agents, 3 to 7 parts of coalescing agents and 20to 30 parts of water. The preparation method of the environment-friendly inner wall paint comprises the following steps that the fluorine-containing triazine type film forming polymers, the phosphoric acid modified nanometer titanium dioxide, the pigment filling materials, the anti-foaming agents, the dispersing agents and the coalescing agents are proportionally put into a high-speed mixing machine to be mixed for 20 to 30min, and are then charged into a ball milling tank; after the ball milling treatment is performed for 5 to 8h, mixed powder is obtained; then, water is added into the mixedpowder; at the rotating speed being 1200 to 1500 turns per minute, dispersion is performed for 10 to 15 minutes; next, curing is performed for 2 to 5 days; sampling for inspection is performed; afterthe products are qualified, sieving and packaging are performed. The environment-friendly inner wall paint disclosed by the invention has the advantages that the price is cheap; the formaldehyde absorption and decomposition effects are obvious; the efficiency is high; the secondary pollution cannot be caused; the visible light response speed is high; the fireproof performance and the bonding capability are high; the weathering performance is good.

Description

technical field [0001] The invention relates to the technical field of building decoration materials, in particular to an environmentally friendly interior wall paint and a preparation method thereof. Background technique [0002] In recent years, with the improvement of people's living standards, various decorative and decorative coatings emerge in an endless stream. While these decorative and decorative coatings bring people a sense of comfort, they also bring about increasingly serious environmental problems. The body takes a fatal toll. As one of the decorative paints, interior wall paint is closely related to people's life and work because it is directly painted on the inner surface of buildings or structures. More attention should be paid to the toxicity and tasteless characteristics. [0003] The important substance that interior wall paint pollutes the indoor air environment is formaldehyde. It is mainly released through the degradation of wood adhesives and plasti...
