Abstract

The invention relates to a building material, and in particular to a building decorative material surface coating, which is prepared from the following materials in parts by weight: 45 to 60 parts of octamethylcyclotetrasiloxane, 10 to 15 parts of ethylchlorosilane, 1 to 5 parts of methyl ethyl ketone, 5 to 8 parts of methyl ethyl ketone, 0.5 to 0.8 parts of titanium dioxide, 0.5 to 1 part of catalyst and 5 to 15 parts of dimethylpropane. The building decorative material surface coating disclosed by the invention can be solidified under room temperature, the solidification time is short, the building decorative material surface coating has good adhesion, and can be stuck with a variety of materials, the organic solvent resistance is high, and the sealing property is good.

Description

technical field [0001] The invention relates to building materials, especially the surface coating of building decoration materials. Background technique [0002] Due to the unique structure of the surface coating of building decoration materials, which combines the properties of inorganic materials and organic materials, it has excellent high and low temperature resistance, water resistance, corrosion resistance, and atmospheric aging resistance. It is mainly used in sealing, bonding, coating, etc. , waterproof, moisture-proof, inert surface treatment, etc. However, the surface coating of existing building decoration materials has long curing time, low cohesive force and poor resistance to organic solvents. Contents of the invention [0003] In order to solve the above problems, the present invention provides a surface coating of building decoration materials with short curing time and strong cohesive force. The specific technical scheme is: [0004] The surface coating...
