Weather-resistant paint and preparation method thereof

Abstract

The invention provides weather-resistant paint and a preparation method thereof. The weather-resistant paint is prepared from the following ingredients in parts by weight: 30 to 42 parts of pure acrylic emulsion, 13 to 21 parts of pigment fillers, 8 to 12 parts of water glass, 0.5 to 1.2 parts of tea polyphenol, 0.05 to 0.15 part of antioxidant, 5 to 10 parts of sodium carboxymethylcellulose, 8 to 15 parts of diatomite, 1 to 5 parts of propylene glycol methyl ether acetate, 1 to 3 parts of rosin and 15 to 25 parts of water. The weather-resistant outer wall paint can be coated and brushed on an outer wall in modes of scraping coating, spray coating and the like; the paint drying time is short; the weather-resistant performance of the outer wall paint is high; the service life of the paint is prolonged; meanwhile, a good contamination resistant effect and a waterproof characteristic are realized; in addition, certain antiseptic and mildew proofing effects are also achieved; the weather-resistant paint belongs to paint with various functions; the application range is wide; the requirements of people on the outer wall paint are met.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a weather-resistant coating 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 blisters There will be qualitative changes such as shedding and powder removal; the third is that...

[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

However, fluororesin is relatively expensive, and its use in building exterior wall finishes is subject to great restrictions.
