Problems solved by technology

Among the water-based coatings, the common imitation porcelain coatings occupy a dominant position in the market, which has the advantages of high whiteness, convenient construction and low price, but its disadvantages are low hardness, not resistant to scrubbing, and a small amount of waste water in the production process and waste residue discharge, short service life, etc.
In recent years, several new paints with high hardness and scrub resistance have appeared on the market, such as corundum, tempered paint, etc., but they have short storage period, poor stability, low whiteness, waste water and slag discharge during the production process, and difficult construction. , Disadvantages such as high product prices
Moreover, the existing water-based paints are all liquid, which is not conducive to use and storage
[0003] With the improvement of people's living standards, the requirements for the living environment and quality are getting higher and higher. For architectural coatings, not only are they required to have superior performance, but they are also required to be "green" products, that is, non-toxic, tasteless, and pollution-free. However, none of the existing coatings can meet these requirements.

[0023] In a preferred embodiment of the present invention, the powder water-based green tempered paint is formed by uniformly mixing powdery adhesive, curing agent and filler, and the weight percentage of the adhesive, curing agent and filler is:

[0024] Adhesive 0.5%~5.0%

[0025] Curing agent 5.0%~30.0%

[0026] Filler 40.0%~80.0%

[0027] Described tackiness agent is made up of polyvinyl alcohol, hydroxyalkyl cellulose and sodium silicate, and its weight accounts for the percentage of powder water-based green toughened paint total amount as:

[0028] Polyvinyl alcohol 0.5%~3.0%

[0029] Hydroxyalkyl Cellulose 0.5%~5.0%

[0030] Sodium silicate 0.5%~3.0%

[0031] Described curing agent is made up of magnesium oxide, magnesium chloride, calcium hydroxide, basic magnesium carbonate and magnesium sulfate, and its weight accounts for the percentage of powder water-based green tempered paint total amount as:

[0032] Magnesium oxide 2.0%~1 5.0%

[0033] Magnesium chloride ...

Description

technical field [0001] The invention relates to a paint composition, in particular to a tempered paint. Background technique [0002] In the field of architectural wall coatings industry, there are various types of coatings with different performances, and water-based coatings are currently the main ones. Among the water-based coatings, the common imitation porcelain coatings occupy a dominant position in the market, which have the advantages of high whiteness, convenient construction and low price, but its disadvantages are low hardness, not resistant to scrubbing, and a small amount of waste water in the production process And waste residue discharge, short service life, etc. In recent years, several new paints with high hardness and scrub resistance have appeared on the market, such as corundum, tempered paint, etc., but they have short storage period, poor stability, low whiteness, waste water and slag discharge during the production process, and difficult construction....
