Sand with exterior wall texture and lotus leaf effect as well as production method thereof

Abstract

The invention discloses sand with exterior wall texture and lotus leaf effect as well as a production method thereof. The sand with exterior wall texture is prepared by the following raw materials in percentage by mass: 10.0-20.0% of water, 0.2-0.3% of hydroxyethyl cellulose, 0.2-0.3% of an antifoaming agent, 0.1-0.2% of a pH conditioning agent, 0.1-0.3% of a wetting agent, 0.3-0.6% of a dispersant, 1.0-1.5% of glycol, 0.9-1.2% of a film forming auxiliary agent, 2.0-10.0% of titanium dioxide, 5.0-15.0% of coarse whiting, 15.0-20.0% of an acrylic acid emulsion, 5.0-10.0% of a wax emulsion, 0.2-1.0% of a bactericide, and 50.0-70.0% of quartz sand. The production process is divided into two stages including production of base materials and paint mixing. The sand has an automatically cleaning function, which is similar to lotus leaf effect, other performances of the sand meet the national standard JG / T24-2000 requirement, comprising: storage stability, artificial aging resistance, cracking resistance at initial stage, shock resistance, water resistance, alkali resistance, etc.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to exterior wall textured sand with a lotus leaf effect and a production method thereof. Background technique [0002] Texture sand is a new type of environmentally friendly, approximately round quartz sand, which can create thick build art paints with classic sand grain patterns. It is widely used as a high-grade raw material for decoration, engineering construction, and coatings. It has the characteristics of high hardness and good fluidity. Sand for real stone paint, colored quartz sand, sand for epoxy flooring, etc. can be processed according to different requirements of customers. Round-grained quartz sand is finely processed from natural quartz sand through multiple processes. The product has a high silicon content and is in a round granular shape. It has good air permeability, good fluidity and high compressive strength. Suitable for many purposes, such as oil f...

AI Technical Summary

Problems solved by technology

Most of the popular external wall texture sands on the market are made of styrene-acrylic emulsion, titanium dioxide and heavy calcium, combined with additives. The surface of the membrane is rough, which is easy to hide dirt, affecting the appearance and service life of the wall

Many patent documents have reported the synthesis research and application of texture sand with different properties, which can not only meet the requirements of the national standard JG / T24-2000 sand wall texture coating, but also have the self-cleaning function of lotus leaf effect. The research on texture sand has not been reported so far.
