Problems solved by technology

[0005] 1. Organic water-based fireproof coating, the main base material is polyacrylic acid emulsion, styrene modified emulsion, etc. It has the advantages of non-toxic and odorless, high cold resistance and heat preservation, but its flame retardancy and heat resistance are poor , high temperature is easy to be sticky, easy to stick to dust, low temperature is easy to become brittle, and the air permeability is poor. It will be withdrawn from the market after being used for a period of time
[0006] 2. Inorganic water-based fire retardant coatings. In order to solve the problems of organic fire retardant coatings, people focus on the research and development of inorganic fire retardant coatings, so inorganic fire retardant coatings based on silicates came into being. Easy to produce smoke and emit poisonous gas to varying degrees
[0009] At present, there is no water-based intumescent flame retardant coating for interior decoration on the market that can solve the following possible problems at the same time:

Abstract

The invention relates to an aqueous indoor smoke-free fire-proof coating, which comprises the following components in parts by weight: 20-28 parts of water, 3-5 parts of multi-wall carbon nanotube, 2-3 parts of 10 percent sodium hexametaphosphate, 0.1-0.2 parts of antifoaming agent, 0.1-0.2 parts of wetting agent, 0.1-0.5 parts of filming auxiliary agent, 0.1-0.3 parts of dispersing agent, 10-20 parts of dehydration catalyst, 8-10 parts of foaming agent, 7-85 parts of carbonizing agent, 10-14 parts of smoke suppression flame retardant, 11-15 parts of titanium dioxide, 11-23.5 parts of acetic styrene-acrylic emulsion, 0.2 parts of bactericide, 0.6-1.2 parts of thickening agent and 0.1-0.2 parts of adjusting agent. The multi-wall carbon nanotube modified by amphiphilic polymer is added, so that the strength and the expansion ratio of a charring layer after firing of the fire-proof coating are improved.

Description

technical field [0001] The invention relates to a paint, in particular to a water-based indoor smoke-free fireproof paint. Background technique [0002] According to the type of dispersion medium, fire retardant coatings can be divided into solvent-based fire retardant coatings and water-based fire retardant coatings. [0003] Solvent-based fireproof coatings are gradually being phased out because of their greater damage to the environment and people's health. [0004] Water-based fire-resistant coatings began to be developed and applied in the 1930s, and product quality and performance were gradually improved. Since the 1990s, with the improvement of environmental awareness and technological level, water-based fire-resistant coatings have developed rapidly. Water-based fire retardant coatings are divided into organic, inorganic and inorganic-organic composite fire retardant coatings. [0005] 1. Organic water-based fireproof coating, the main base material is polyacrylic ...
