Zusammenfassung:The present invention relates to a primer comprising raw material components by mass in part: 10-15 parts of water, 80-100 parts of elastic emulsion, 20-30 parts of silicate, 0-1.5 part of simethicone, 0.15-0.4 part of preservative, 10-15 parts of titanium dioxide, 0.4- 0.5 part of polyethylene wax, 0.4-0.5 part of organic amine, 0.15-0.4 part of mildew preventive, 25-30 parts of calcium carbonate, 0.05 part of lithopone, 1-1.2 parts of bentonite, and 1.5-2.5 parts of anti-settling agent. The primer not only has excellent ductility and waterproof performance, but also has certain plasticity, so that the primer can effectively cope with wall changes caused by humid environments and thermal expansion, and the service life of paint can be prolonged.
