Carbon-titanium water-based resin flame-retarding paint and preparation method of carbon-titanium water-based resin flame-retarding paint

Abstract

The invention discloses carbon-titanium water-based resin flame-retarding paint. The carbon-titanium water-based resin flame-retarding paint is prepared from the following components: carbon-titanium modified acrylic resin, a wetting agent, a dispersant, a pigment, functional filling, a de-foaming agent, a flush-rust-proof agent, a film-forming auxiliary agent, an anti-sedimentation agent, a pH (Potential of Hydrogen) regulator, a sterilizer and de-ionized water. The carbon-titanium water-based resin flame-retarding paint disclosed by the invention takes a nanomaterial, namely special modified styrene-acrylic resin, as a film forming substance, and realizes long-period protection under the condition of a relatively thin coating thickness. Furthermore, after the paint is coated, moisture is volatilized to a certain degree and curled hydrophobic molecular chains in the resin start to expand and crossly link, and phase overturning is rapidly realized to eliminate residual moisture out of a paint film. Therefore, the drying speed of the paint is obviously faster than that of a common sticking material and the paint is dried completely, so that the number of construction times of the paint can be reduced, the difficulty of a coating process is greatly reduced and the construction cost is reduced.

Description

technical field [0001] The invention belongs to the field of steel anticorrosion coatings, and in particular relates to a carbon-titanium water-based resin flame-retardant coating and a preparation method thereof. Background technique [0002] Flame-retardant coatings are an important part of fire-resistant building materials. They are coated on the surface of objects to prevent fires from happening, prevent the spread of fire or isolate fire sources, prolong the ignition time of substrates or increase thermal insulation performance to delay structural damage. coating. Among them, the expansion type coating can expand and foam when exposed to fire, and the fire-resistant and heat-insulating layer formed by the expansion and foam can delay the temperature rise of the steel and protect the steel components. This kind of steel structure coating is generally made of suitable latex polymer as the base material, and then combined with flame retardants, additives and other compone...

AI Technical Summary

Problems solved by technology

For this kind of fireproof coating, it is required that the selected emulsion polymer must have good adhesion, durability and water resistance to the steel substrate. At present, the common styrene-modified acrylic emulsion, polyvinyl acetate emulsion, vinylidene chloride emulsion, etc. , there are deficiencies in the above items, and the aging and peeling off of the coating is serious

In addition, the drying speed of construction is slow, and it is easy to cause poor drying and cracking during construction, so multiple constructions are required, the coating process is complicated, and the construction cost is high
