Problems solved by technology

Water-based fire retardant coatings in the domestic market are low in cost, low in toxicity, and less polluting, but have poor moisture resistance and are only suitable for use in dry environments
Although water-based fire retardant coatings in the international market have the above properties at the same time, the price is surprisingly high, which is not suitable for the development needs of the Chinese market.
In addition, most of the existing fire retardant coatings use ammonium polyphosphate-pentaerythritol-melamine (APP-PER-MEL) type flame retardant system. Although the fire retardant coating of this flame retardant system has better fire resistance performance, its durability and water resistance are relatively poor. Poor, when used in an environment in direct contact with water or in a humid environment, its flame retardant is prone to water solubility, salting out, etc., which will cause the fire-resistant coating to fail, thus making the coating lose its fire-proof performance

Abstract

The invention discloses a water-borne inflation type refractory coating and a preparation method thereof. The refractory coating is prepared from the following components: 30-40% of emulsion compound, 40-58% of modified antiflaming system of a nanometer material, 0.3-0.6% of emulsifying agent, 0.2-0.4% of plasticizer, 0.4-0.8% of reinforcing agent, 0.1-0.15% of pigment filler, 0.2-0.6% of dispersing agent and the balance of water. Compared with the prior art, the water-borne inflation type refractory coating has the advantages of excellent environmental performance, simple technology, sufficient raw material resources, proper price and the like and can be widely applied.

Description

technical field [0001] The invention belongs to the technical field of fireproof paint, and relates to a water-based swelling fireproof paint and a preparation method thereof. Background technique [0002] With the development of high-rise buildings, clusters, large-scale industries and the expanded utilization of organic synthetic materials, coatings give people comfortable enjoyment due to their excellent protection and decoration, but most coatings are flammable and flammable. Sex also poses a fire hazard. Therefore, it is increasingly important to develop fire-resistant coatings to adapt to fire safety. [0003] Fire retardant coatings are divided into intumescent and non-intumescent fire retardant coatings according to their fire prevention forms and components. Intumescent fire retardant coatings are the most widely used coatings in China, and can be divided into water-based and solvent-based intumescent fire retardant coatings. Among them, water-based intumescent fi...
