Organosilicon acrylic resin hydrophobic coating

Abstract

The invention provides a technical proposal with hydrophobic lotus-leaf water-ball effect, the product for which is resistant to powdering, to discoloring, dirt and aging, highly resistant to washing and brushing, and resistant to fine cracks; after rubbing, the sample is of excellent hydrophobic property, and the color maintains as new after repeated scrubbing or being placed under the blazing sun for some time. The technical proposal comprises by weight: silicone acrylic emulsion 25-35%, pure acrylic emulsion 15-20%, colorant 20-30%, filler 5-10%, wetting dispersing agent 0.5-0.7%, defoaming agent 0.15-0.2%, thickener A 0.7 swung dash 0.8%, thickener B 0.1 swung dash 0.2%, anti-corrosion disinfecting agent 0.15-0.2%, methyl glycol 2.0 swung dash 2.5%, pH adjusting agent 0.1 swung dash 0.2%, moisture repellent 0.2-0.4%, filming assistant 0.8-1.5%, and the remainder is tap water.

Description

Technical field: [0001] The invention belongs to the technical field of chemical building materials, and relates to a water-based environmental protection paint with excellent weather resistance, waterproof and stain resistance and a preparation method thereof. Background technique: [0002] The paint industry has a history of production and development for many years, but the traditional paint is not only complicated in production process, but also the raw materials used are not fine enough, and many raw materials cause great harm to the human body, resulting in several inevitable defects of traditional paint: One is not environmentally friendly, it contains a variety of chemical elements that cause radiation damage to the human body, which may cause different pathological states of the human body; the other is not waterproof, after the rain, it will leave many traces of water flow, which will seriously affect the appearance of the coating surface and cause long-term blister...

[0002] The paint industry has a history of production and development for many years, but the traditional paint is not only complicated in production process, but also the raw materials used are not fine enough, and many raw materials cause great harm to the human body, resulting in several inevitable defects of traditional paint: One is not environmentally friendly, it contains a variety of chemical elements that cause radiation damage to the human body, which may cause different pathological states of the human body; the other is not waterproof, after the rain, it will leave many traces of water flow, which will seriously affect the appearance of the coating surface and cause long-term blisters There will be qualitative changes such as shedding and powder removal; the third is that the service cycle is short, resulting in frequent repeated construction and affecting normal work

Not only waste property, but also make people lose confidence in the longevity of paint use
