A kind of artificial colored sand adhesive and its application

Abstract

The invention provides an artificial sintered colored sand adhesive and its application. The artificial colored sand adhesive includes the following components: sodium silicate, amphoteric oxide buffer, and phosphate; wherein, the sodium silicate The parts by weight are 80-120 parts, the parts by weight of the amphoteric oxide buffer solution are 5-10 parts, and the parts by weight of the phosphate are 4-6 parts of insoluble phosphate or 12 parts by weight. ‑16 parts of water-soluble phosphate; the present invention screens the active ingredients and proportions through experiments, uses amphoteric oxide buffer and phosphate to modify sodium water glass, and each component synergizes under a specific formula to finally optimize the preparation The artificial colored sand with excellent water resistance and boiling water resistance has broad application prospects and huge market value; the invention has simple technology, can realize industrialized large-scale production, can bring good economic benefits to enterprises, and has broad application prospects. prospect.

Description

technical field [0001] The invention relates to the field of decorative materials, and mainly relates to an artificial colored sand adhesive and its application. Background technique [0002] With the rapid development of the construction industry, personalized paint finishes have become the mainstream of architectural paint exteriors, such as texture paint, imitation brick paint, imitation stone paint, colorful paint, etc. Real stone lacquer uses natural granite granules as coloring material, which has excellent weather resistance and can protect the beauty of buildings for a long time. It can be applied on any shape of building surface. It can be sprayed into multi-color marble effects to fully display natural stone. Its unique shape and rich texture are deeply loved by people. As the proportion of high-rise buildings increases, the demand for real stone paint is increasing. As a decorative material, colored sand has always been an important aggregate of architectural co...

Problems solved by technology

Most of the existing modification ideas start with the improvement of water resistance. One solution is to modify sodium water glass and use amphoteric oxides to seal sodium ions. This method is limited by the limited dissolution ratio of amphoteric oxides. Only part of the water resistance can be improved, and the boiling water resistance cannot be fully achieved. Another method is organic-inorganic compounding, which uses the hydrophobic effect of organic matter to help improve the water resistance of sodium silicate glass, and the help for boiling water resistance is also limited.

Other solutions, such as changing the hardening method of sodium silicate glass, essentially cannot change the dispersion of sodium ions on the surface of colored sand, and will not help the boiling water resistance
