preparation example Construction

[0025] The preparation method of the elastic fireproof coating of the present invention includes the following steps:

[0026] At room temperature, pour 50-100 parts of solvent into the mixing tank;

[0027] Turn on the high-speed mixer and add 80 to 120 parts of epoxy resin;

[0028] After stirring evenly, add 10-20 parts of toughening agent and stir;

[0029] After stirring evenly, add 1 part to 5 parts of white carbon black, 10 parts to 30 parts of wet sericite, 20 parts to 50 parts of titanium dioxide, 1 part to 10 parts of adhesion promoter, and stir for 20 minutes to 25 minutes;

[0030] After stirring uniformly, add 5 to 15 parts of elastic microsphere filler and stir for 10 to 15 minutes to obtain the room temperature curing elastic fireproof coating.

[0031] The elastic fireproof coating with the following composition was specifically prepared by the above preparation method.

Embodiment 1

[0033] In this example, the room temperature curing elastic fireproof coating, its raw materials are composed of: 100 parts of resin (epoxy resin E-44, E-51, E-20 or any combination), curing agent (the selected curing agent is the corresponding resin Normal temperature curing agent) 80 parts, 2 parts of white carbon black, 20 parts of wet sericite, 30 parts of titanium dioxide, 5 parts of adhesion promoter (adhesion promoter is corresponding to the resin system), toughening agent 10 parts, 2 parts of anti-settling agent, elastic microsphere filler (the selected elastic microsphere filler needs to be one of EPDM, neoprene, silicone rubber or any combination) 5 parts, solvent (selected solvent One of ethanol, ethyl acetate, n-butanol or any combination) 100 parts. Use the above-mentioned elastic fireproof coating to pour burning substances (such as alcohol, gasoline) on the surface and then extinguish the fire after it is removed. The adhesion ASTM grade reaches 5B, and the coat...

Embodiment 2

[0035] In this example, the room temperature curing elastic fireproof coating, the composition of each raw material is: 120 parts of resin (epoxy resin E-44, E-51, E-20 or any combination), curing agent (the selected curing agent is the corresponding resin Normal temperature curing agent) 100 parts, white carbon black 1.5 parts, wet sericite 30 parts, titanium dioxide 50 parts, adhesion promoter (adhesion promoter is the accelerator corresponding to the resin system) 3 parts, toughening agent 15 parts, 3 parts of anti-settling agent, 10 parts of elastic microsphere filler (the selected elastic microsphere filler must be one or any combination of materials such as EPDM, neoprene, silicone rubber), solvent (selected solvent One or any combination of ethanol, ethyl acetate, n-butanol) 80 parts. Use the above-mentioned elastic fireproof coating to pour burning substances (such as alcohol, gasoline) on the surface and then extinguish the fire after it is removed. The adhesion ASTM ...

Abstract

The invention discloses elastic fire-retardant paint and a preparation method thereof. The paint is prepared by sequentially adding, by weight, 80-120 parts of epoxy resin, 50-100 parts of a curing agent, 1-5 parts of white carbon black, 10-30 parts of wet-process sericite, 20-50 parts of titanium dioxide, 1-10 parts of an adhesion promoter, 10-20 parts of a flexibilizer-liquid butadiene-acrylonitrile rubber, 1-5 parts of an anti-sedimentation agent-oxidized polyethlene wax slurry, 5-15 parts of elastic microsphere filler and 50-100 parts of a solvent and mixing and stirring the materials. The fire-retardant paint is good in surface elasticity and is obviously changed compared with a traditional epoxy coating; the surface elasticity can be regulated according to the actual needs, and meanwhile the thickness of coatings can be controlled to range from 30 micrometers to 50 micrometers; the adhesion ASTM level of the coatings formed on a metal substrate and a composite substrate reaches 5B, and the coatings cannot be cracked or fall off under the high temperature and low temperature (ranging from minus 20 DEG C to 120 DEG C) working conditions and cannot fall off under the strong acid and strong base conditions.

Description

Technical field [0001] The invention belongs to the technical field of chemistry and chemical engineering and the technical field of security, and relates to a special room temperature curing elastic fireproof coating and a preparation method thereof. Background technique [0002] Traditional coatings usually have problems such as environmental pollution and poor adhesion. In recent years, people have conducted a lot of research on the above problems of coatings. In the application field of arson heat insulation coatings, there are various combination formulas for different special purposes, among which epoxy resin-based coatings have been widely used. In epoxy resin-based coatings, the problem of epoxy-based coatings having excess rigidity and poor impact resistance has not been fully paid attention to. In particular, there are few targeted studies on how to make epoxy-based coatings have better elasticity. [0003] Epoxy based coatings have the advantages of strong anti-corrosio...
