Embodiment 1

[0031] In order to meet the requirements of "JB / T-9755-1995 Synthetic Emulsion Exterior Wall Paint Standard". The performance of the coating is mainly affected by the properties of the binder.

[0032] Firstly, screen and compare domestic binders suitable for latex paint coatings:

[0033]

[0034] Note: The water resistance shown in the above table is the data of the latex with 100um paint film coating paint on the glass plate, dried at 50℃ for 1 hour, and then soaked in water for 96 hours.

[0035] As can be seen from the above table, the performance requirements are compounded. Proceed to the next performance test.

[0036] The 4 emulsions were made into latex paint according to the following formulas:

[0037]

[0038]

[0039] Make a standard sample with the prepared latex paint, and conduct a performance test according to "JB / T-9755-1995 Standard for Synthetic Emulsion Exterior Wall Paint".

[0040] See the table below for the data:

Abstract

The invention relates to a safe and environment-friendly type abrasion-resistant self-cleaning latex paint and a preparation method thereof. The latex paint is prepared from the following components in parts by weight: 390 to 420 parts of emulsion, 20 to 30 parts of film forming additive, 5 to 50 parts of silicon sol, 2 to 4 parts of multifunctional ammine additive, 5 to 10 parts of hydrophobic agent, 2 to 5 parts of wetting agent, 7 to 8 parts of dispersant, 2 to 5 parts of defoaming agent, 1 to 3 parts of cellulose, 2 to 4 parts of thickener, 240 to 260 parts of inorganic filler, 250 to 270 parts of water, 2 to 4 parts of preservative, 1 to 2 parts of anti-mildewing agent and 15 to 20 parts of propylene glycol. Compared with the prior art, the latex paint has the advantages that the compactness of a paint film is good, the hardness is high, the abrasion-resistant property is good, static electricity is not produced, and various dust in air is difficult to adhere; the preparation method is simple, the controllability is good, the green and environment-friendly effect is achieved, the technical defect of poor dirt resistance in a latex paint is effectively overcome, the service life of the latex paint is prolonged, the economy is good, the industrialized expanding production is easy, and the application prospect is good.

Description

technical field [0001] The invention belongs to the technical field of safe and environmentally friendly pigments and dyes, and relates to a safe and environmentally friendly wear-resistant self-cleaning latex paint and a preparation method thereof. Background technique [0002] Latex paint is a common name for latex paint. It was born in the middle and late seventies of the 20th century. It is a large class of thin-coated paint represented by acrylate copolymer emulsion. Latex paint is a water-dispersible paint. It is based on synthetic resin emulsion, and the filler is refined by adding various additives after grinding and dispersing. Latex paint has many advantages that are different from traditional wall paints, such as easy brushing, fast drying, and water-resistant paint film. [0003] However, as the formulations of the existing latex paints on the market become more and more transparent, the crazy price war has caused the performance of latex paints to continue to d...
