AI Technical Summary

Problems solved by technology

However, the density of round sand is high, adding it to the paint and spraying it on the outer wall will increase the weight of the building, and there is a danger of falling off the wall due to wind and sun, and it will also affect the dispersion of the paint.

Abstract

The invention discloses a rounded grain mortar aqueous coating with stable coating film and simple construction. The rounded grain mortar aqueous coating is characterized by being prepared from the following raw materials in parts by weight: 25-28 parts of pure acrylic emulsion, 8-10 parts of redispersible latex powder, 7-9 parts of glycidyl acrylate, 1-2 parts of NP-10, 3-5 parts of sodium silicate, 5-7 parts of OK powder, 1-2 parts of triphenyl phosphite, 2-3 parts of dextrin, 10-13 parts of kaolin, 3-4 parts of glycerinum, 6-8 parts of modified rounded grain mortar and 25-30 parts of water. The rounded grain mortar aqueous coating is reasonable in formula, safe and environment-friendly due to addition of the aqueous pure acrylic emulsion, light in weight due to addition of the modified rounded grain mortar, pleasant in smell, good in dispersity, good in waterproof property, relatively high in strength, attractive and graceful in appearance, simple to construct and high in practicability, and does not need to be diluted with water, a coating film is stable, good in weather resistance, free of dropping, safe and reliable, and different decoration requirements can be met.

Description

technical field [0001] The invention relates to a coating and a preparation method thereof, in particular to a round-grain mortar water-based coating with stable coating film and simple construction and a preparation method thereof. Background technique [0002] Round sand is made by crushing and rounding natural quartz. It has high Mohs hardness, round particles without sharp corners and flake particles, no impurities, high purity, high silicon content and high refractoriness. It is widely used in decoration, engineering construction, coatings, etc. high-grade raw materials. The product has high silicon content, is pelletized, has good air permeability, good fluidity, and high compressive strength. It is used in coatings, with a suitable particle size ratio and small stacking gaps, which saves the amount of resin and is compatible with various resins. Good solubility, acid resistance, alkali resistance, chemical solvent resistance, hot water resistance. However, the densi...
