Abstract

The invention discloses composite paint with good storage stability and a preparation method of the composite paint. The composite paint is prepared from the following components in parts by weight: 25 to 32 parts of water, 0.3 to 0.5 part of hydroxyethyl cellulose, 0.5 to 0.8 part of defoaming agent, 10 to 15 parts of titanium dioxide, 5 to 8 parts of talcum powder, 22 to 30 parts of heavy calcium powder, 0.5 to 0.8 part of stabilizer LOPON ST, 15 to 20 parts of potassium silicate solution, 5 to 8 parts of emulsion and 0.5 to 1 part of reinforcing agent. The test verifies that the storage stable period of the composite paint is about 6 months, so that the storage stability is greatly improved compared with that of the paint in the prior art.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a composite coating with good storage stability and a preparation method thereof. Background technique [0002] With the wide application of latex paint in the construction field, people gradually realize the impact of organic bonding materials in latex paint on the environment and human body, and there are problems in safety, so inorganic paint is getting more and more attention. [0003] Inorganic coatings can be divided into two categories: one is inorganic coatings that basically do not contain or only contain a small amount of organic substances as additives. Due to its "pure inorganic nature", this kind of product has decoration defects such as hard, brittle, and poor hand feeling, so it is not suitable for surface decoration. The other type is inorganic coatings with a total organic content of about 3-5%. This type of coating generally uses 5-8% emulsion to improve the t...
