Problems solved by technology

After these paints and coatings are used in harsh environments for a period of time, the paint film will produce many disadvantages, such as weathering, cracking and falling off, which will affect human health indoors and affect the environment outdoors.
The paints and coatings used to make wood and steel product coatings often have the defects of corrosion resistance, aging resistance, and poor adhesion. Over time, they crack and fall off in pieces, and their service life is short, which affects various products and products. The beauty of the city environment
Some water-based paints add a certain amount of mica powder, but the amount added is a small amount, and the mica powder added is generally only for heat insulation and waterproofing, instead of using mica powder as a body pigment, and mica powder has corrosion resistance and anti-corrosion properties. Aging, anti-cracking, heat preservation, heat insulation, sound insulation and other properties cannot be fully utilized

Abstract

The invention relates to a environment- friendly water- borne paint. The comprised components and their weight proportion are as follows: mica pigment 40 -50%, water 7- 30%, synthetic resin 25- 60%, emulsifying agent 0.05- 0.1%, wetting agent 0.05- 0.1%, defoaming agent 0.1- 0.2%, pH modifying agent 0.05- 0.1%, film adjuvant 1- 2%, thickening agent 0.5- 1%, dispersing agent 0.1- 0.2%, conservative 0.05- 0.2%. It is characterized by strong properties of wearing resistance, covering power, antiweatherability, age resistance, thermal insulating and heat insulating property, non toxic, non smell and no pollution.

Description

technical field [0001] The invention relates to a water-based paint, in particular to an environment-friendly water-based paint. Background technique [0002] At present, the common interior and exterior wall coatings, paints, anti-corrosion coatings and floors on the market are talcum powder, titanium dioxide, heavy calcium, light calcium, kaolin, etc. as pigments and fillers. After these paints and coatings are used in a harsh environment for a period of time, the paint film will produce many disadvantages, such as weathering, cracking and falling off, which will affect human health indoors and affect the environment outdoors. The paints and coatings used to make wood and steel product coatings often have the defects of corrosion resistance, aging resistance, and poor adhesion. Over time, they crack and fall off in pieces, and their service life is short, which affects various products and products. The beauty of the city environment. Some water-based paints add a certai...
