Inorganic silicate coating, preparation method thereof and application of coating

Abstract

The invention relates to the technical field of coatings for inner walls and outer walls of buildings, in particular to an inorganic silicate coating, a preparation method thereof and an application of the coating. The inorganic silicate coating is prepared from, by weight, 18-30 parts of deionized water, 0.1-0.8 part of cellulose, 0.5-1.5 parts of dispersing agents, 0.01-1.0 part of wetting agents, 0.01-1.0 part of defoaming agents, 10-20 parts of titanium dioxide, 10-20 parts of ground calcium carbonate, 10-20 parts of talcum powder, 5-10 parts of emulsion, 20-30 parts of modified potassiumsilicate, 0.01-5 parts of stabilizing agents and 0.01-5 parts of hydrophobic agents. The modified potassium silicate is selected from one or more of VB-2837 and INOCOT 955 or K-2837, and the emulsionis selected form one or more of styrene-acrylic ester and pure acrylic emulsion. The coating reaches the standard without a detected VOC (volatile organic compound) and good in fungus resistant and falling-off prevention performances.

Description

technical field [0001] The invention relates to the technical field of coatings for interior and exterior walls of buildings, in particular to an inorganic silicate coating and its preparation method and application. Background technique [0002] In the prior art, products such as latex paint, real stone paint, textured or colorful paint are mainly used for painting the interior and exterior walls of domestic buildings to protect and decorate the wall. These products have a common feature, that is, emulsion is used as the main Adhesive substances (10-50%), and add a certain amount of film-forming aids to assist emulsion film formation, and emulsions and film-forming aids are the most important sources of VOC for these coatings. VOC stands for Volatile Organic Compounds, which have a huge impact on human health. When the VOC in the room reaches a certain concentration, people will feel headache, nausea, vomiting, fatigue, etc. in a short time. decline and other serious cons...

AI Technical Summary

Problems solved by technology

At present, although the emulsion production process and paint formula can relatively reduce the VOC content, they cannot meet the standard of VOC undetected; the adhesion between the paint and the wall is low, and it is easy to fall off from the wall and affect the performance of the paint. ; The wall paint is acidic and the pH is lower, the easier it is for mold to grow on the wall. Mold reproduces with spores. It is a common name for filamentous fungi. It has strong adaptability and can spread and reproduce anywhere in nature. Some species It is easy to cause food deterioration, animal, plant and human diseases. Long-term inhalation and contact with mold can cause allergic symptoms and respiratory diseases, such as hay fever, asthma, bronchitis, tonsillitis, and people with low immunity may also cause headaches, Fever, skin or mucous membrane inflammation and poisoning, or the production of carcinogens, causing fungal pneumonia and other diseases, allergic diseases
