Abstract

The invention discloses an indoor environment-friendly dry powder paint with microwave absorbing and flame-retardant functions, and a preparation method and a construction method thereof. The indoor environment-friendly dry powder paint comprises the following components by weight percent: 20-50% of latex powder, 5-30% of titanium dioxide, 5-30% of calcium carbonate, 5-10% of silica, 5-10% of talcum powder, 10-40% of microwave-absorbing powder, 5-25% of halogen-free flame retardant, 5-15% of cellulose, 0.1-0.7% of solid defoaming agent, 2-8% of mildew preventive, 0.5-2% of assistant and 0.05-8% of paint. The obtained product has excellent microwave absorbing function and excellent flame-retardant effect; the flame-retardant effect can reach level V0; the dosage of the assistant is effectively reduced; and the VOC (volatile organic compound) emission of the dry powder paint is zero. Thus, the product is convenient to package, simple to transport, convenient to construct, free of special requirements, free of poison or pungent smell, and free of an injury to skin and a respiratory tract of a person, and can achieve ultra-thin construction; and the smallest coating thickness can be up to 20 microns.

Description

technical field [0001] The invention belongs to the technical field of architectural paint preparation, and in particular relates to an indoor environment-friendly dry powder paint with wave-absorbing and flame-retardant functions, a preparation method and a construction method thereof. Background technique [0002] With the rapid development of the national economy and the enhancement of people's awareness of environmental protection, the application of new environmentally friendly water-based coatings in the field of architectural decoration has become increasingly widespread. Indicators closely related to people's health have become important indicators for evaluating the living environment. [0003] Although these problems have been seriously concerned, the impact of volatile organic compounds (Volatile Organic Compounds, VOC for short) in architectural latex coatings on the human body and the environment still needs to be resolved urgently. In recent years, my country...
