Problems solved by technology

There are also studies using inorganic resin as the main binder of the fire retardant coating to improve the strength of the coating, but the fire retardant coating prepared by using inorganic resin as the binder is easy to crack at high temperature, and the bonding strength is low

Embodiment 1

[0011] Add a certain proportion of water into the reaction kettle, and add titanium dioxide, lithopone, silica fume powder, lime calcium powder, silica sol, lactate, flame retardant, defoamer, multifunctional additives and thickeners in proportion , add an appropriate amount of water and stir until evenly mixed. In the stirred mixture, the weight of each component is: titanium dioxide 400kg, lithopone 400kg, silica fume powder 400kg, ash calcium powder 400kg, water 4400kg, silica sol 4000kg,

[0012] Milk ester 600kg, flame retardant 20kg, defoamer 10kg, multifunctional additive 25kg, thickener 15kg.

[0013] In this example, the defoamer used is silicone defoamer, the multifunctional additive is multifunctional additive AMP-95, the milk ester is butyl acrylate emulsion, the thickener is XJ-AT702, and the flame retardant for aluminum hydroxide.

[0014] In this implementation, there is no chemical reaction in the production process, and only a small amount of dust is generate...

Abstract

The invention provides a water-based fireproof coating which is prepared from the following components in parts by weight: 40 parts of titanium dioxide powder, 40 parts of lithopone, 40 parts of silicon ash powder, 40 parts of ash calcium powder, 440 parts of water, 400 parts of silica sol, 60 parts of milk ester, 2 parts of fire retardant, 1 part of defoaming agent, 2.5 parts of multifunction additive and 1.5 parts of thickening agent. According to the water-based fireproof coating provided by the invention, the defects of the existing fireproof coating that the heat stability is poor and the phenomenon of the increasing of smoke generating quantity is caused due to a large quantity of organic resins existing in the existing fireproof coating are overcome. The water-based fireproof coating is good in fireproof and heat-insulating performance, good in bonding force and high in strength, and is not influenced by the cycling of high and low temperatures. A coating layer obtained by the water-based fireproof coating has the characteristics of being good in water resistance, acid resistance and salt corrosion resistance, difficult to fall off, stable to store, good in decoration, convenient to construct and the like; smoke is not generated or small amount of smoke is generated during the burning of the coating layer.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a water-based fireproof coating. Background technique [0002] Fire retardant coatings are applied on the surface of combustible substrates, which can reduce the flammability of the surface of the coated materials, retard the rapid spread of fire, or be coated on the surface of structural materials to improve the fire resistance limit of components; fire retardant coatings are generally composed of base Composed of materials, dispersion medium, flame retardant, filler, additives (plasticizer, stabilizer, waterproofing agent, moisture-proofing agent, etc.), its flame retardant principle is generally divided into two types: intumescent and non-expandable, non-expandable fireproof The coating relies on its own high flame retardancy or non-combustibility to achieve the purpose of flame retardancy and fire prevention. To achieve a good fire prevention effect, it must be painted very thickly, a...
