Anti-yellowing steel coating for old wall body and preparation method thereof

Abstract

The invention discloses an anti-yellowing steel coating for an old wall body and a preparation method thereof. The anti-yellowing steel coating is prepared from anti-yellowing powder, fibrous plaster, calcium hydroxide, calcium carbonate powder and substrate adhesive auxiliary powder in the ratio of (0.5-3): (5-25): (200-400): (600-800): (5-12) in parts by weight. The preparation method comprises the steps of: preparing anti-yellowing powder, fibrous plaster, calcium hydroxide, calcium carbonate powder and substrate auxiliary adhesive powder; mixing the powders and the like. By the anti-yellowing steel coating, the problem that decoration quality and effect are seriously affected when the old wall body is alkalized and yellowed after the old wall body is decorated and repaired is overcome, the bonding strength and the flexibility performance of the coating are obviously improved, meanwhile the dosage of high-price adhesive auxiliary powder can be decreased, the coating is an architectural decorative material with the advantages of environmental friendliness, energy saving and stable quality. The raw materials are low in price and the preparation method is simple and easy to operate.

Description

technical field [0001] The invention relates to a paint and a preparation method thereof, in particular to an anti-yellowing tempered paint for old walls and a preparation method thereof. Background technique [0002] With the improvement of daily life, people pay more attention to the decoration environment and quality of living houses. As the most common decoration material, paint has higher and higher quality requirements.

Water-resistant tempered paint, ordinary putty powder, ordinary 308 paint and 888 paint commonly used at present, in the process of renovation and renovation of old walls, the walls will have varying degrees of alkali and yellowing, which seriously affects the quality of decoration and Decoration effect

Although there is anti-yellowing water for tempered wall coatings on the market, the aqueous solution not only increases the cost of transportation and packaging, but also increases the difficulty of construction, and there may even be uneven distribution of water and powder at the construction site, making it difficult to guarantee anti-aging. Yellowing effect, the overall effect of the paint is still not guaranteed
