Abstract
The invention provides a kieselguhr veneer coating which comprises the following components in percentage by mass: 25-28% of white cement, 40-45% of heavy calcium carbonate powder, 28-30% of kieselguhr, 0.2-0.4% of ethyl cellulose ether, 0.1-0.5% of starch ether and 0.01-1.1% of defoaming agent. The invention also provides a construction method of the kieselguhr veneer coating, which is characterized by comprising the following steps: adding water accounting for 30-35 wt% of the kieselguhr indoor coating, immersing for 5-15 minutes, stirring for 5 minutes, and painting or spraying; and after 30-60 minutes of surface drying, carrying out secondary painting or spraying, wherein the coating thickness of the two construction processes is 2-3mm. The kieselguhr veneer coating is prepared from the kieselguhr used as the functional material, white cement used as the cementing material, heavy calcium carbonate powder used as the filler, ethyl cellulose ether and starch ether used as water retention agents and a right amount of defoaming agent; the kieselguhr veneer coating does not release harmful gas, and regulates the indoor humidity by utilizing the porous ventilation characteristic of the natural kieselguhr; and by using the kieselguhr with small heat conductivity coefficient, the kieselguhr veneer coating has the comprehensive effects of thermal insulation, fire resistance, energy saving and environmental protection.
