Abstract

The invention discloses waterproof mildew-proof inner wall powder paint and a production process thereof. The powder paint comprises the following raw materials in parts by weight: 60 to 80 parts of diatomaceous earth, 70 to 90 parts of fly ash, 20 to 30 parts of talc, 15 to 30 parts of montmorillonite, 8 to 20 parts of aluminum hydroxide powder, 5 to 10 parts of bamboo charcoal fiber, 1 to 5 parts of antimony trioxide, 0.6 to 2 parts of sodium hypochlorite, 1 to 3 parts of nano-zinc oxide, 0.2 to 0.6 part of Kathon, 0.1 to 0.5 part of a dispersant, 0.2 to 0.8 part of a wetting agent and 0.1 to 0.3 part of a defoaming agent. The production process includes diatomaceous earth purification and mixed ball milling. The waterproof mildew-proof inner wall powder paint has the advantages of safety, environmental friendliness, bacteria resistance and bacteriostasis, water proofness, mildew proofness, good fire-proofing performance and simple production process and is suitable as inner wall powder paint.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a waterproof and mildewproof interior wall powder coating and a production process thereof. Background technique [0002] Today, low-carbon environmental protection, energy conservation and emission reduction are the basic principles for the sustainable economic development of various countries in the world. With the development of society and the improvement of living standards, people's awareness of environmental protection and health has been significantly enhanced, and the requirements for the comfort and safety of the living environment are getting higher and higher. Indoor temperature, air relative humidity, and air quality are important environmental parameters for living comfort. When the indoor temperature is 20-23°C, the relative humidity is 50-60%, the VOC content is low, and the negative ion content is high, the human body feels comfortable and beneficial ...
