Description
Technical Field
The invention belongs to the technical field of fire-resistant coatings, and particularly relates to a water-based epoxy resin fire-resistant coating, a preparation method and application thereof.
Background
The traditional epoxy resin coating must use an organic solvent in the using process, so that the system contains organic volatile matters, which not only causes serious pollution to the environment, but also has great threat to human health. The waterborne epoxy resin coating reduces the damage to the environment and human body, but the caking property and the mechanical property of the existing waterborne epoxy resin coating are reduced, so that the coating is easy to crack and fall off, thereby limiting the use of the waterborne epoxy resin coating.
Disclosure of Invention
The invention provides a water-based epoxy resin fire-resistant coating, a preparation method and application thereof aiming at the problems in the prior art, and solves the problems of low mechanical strength, poor cohesiveness, poor impact resistance and poor crack resistance of the water-based epoxy resin fire-resistant coating in the prior art.
In order to solve the technical problems, the invention adopts the following technical scheme:
one of the purposes of the invention is to provide a water-based epoxy resin fire-resistant coating, which comprises the following components:
the preparation method of the acrylic acid modified bisphenol A epoxy resin comprises the following steps:
respectively adding 100 parts of bisphenol A epoxy resin E20 and 2 parts of p-tert-butyl catechol into a reactor, heating to 93 ℃ under the condition of stirring, then dropwise adding a mixed solution of 18 parts of methyl methacrylate and 1 part of N, N-dimethylaniline, finishing dropwise adding after 1.5 hours, and carrying out heat preservation reaction for 3 hours to obtain the acrylic acid modified bisphenol A epoxy resin.
Wherein, the p-tert-butyl catechol is a polymerization inhibitor in the reaction process, the N, N-dimethylaniline is a catalyst in the reaction process, and 1 part of catalyst is added in the reaction process, so that the reaction time is greatly reduced, and the reaction is more thorough.
The preparation method of the melamine modified phenolic resin comprises the following steps:
adding 5 parts of 27 wt% formaldehyde solution into a reaction kettle, adjusting the pH to 8.0 by using 25 wt% NaOH solution, adding 0.2 part of phenolic resin, adding 6 parts of melamine, heating to 90 ℃, keeping the temperature for reaction for 2 hours, cooling to room temperature, and thus obtaining the melamine modified phenolic resin.
In the prior art, common melamine-formaldehyde resin and phenolic resin used in the fire-resistant coating have poor high-temperature resistance, and when the fire-resistant coating is used at a higher temperature, the flow property is not very good, a smooth and compact cured layer cannot be formed, pinholes are easy to appear on the surface of the fire-resistant coating, and the stain resistance and scratch resistance are poor. The melamine modified phenolic resin used in the invention replaces common melamine-formaldehyde resin and phenolic resin to resist, the high temperature resistance and high temperature performance of the fire-resistant coating are improved, when the fire-resistant coating is used at a higher temperature, the fire-resistant coating has good fluidity, a smooth and compact cured layer is formed, pinholes are not easy to appear on the surface of the fire-resistant coating, and the fire-resistant coating is good in stain resistance and scratch resistance.
The glass fiber has a fiber diameter less than or equal to 30 mu m and a length-diameter ratio of 12: 1 of glass fibers; the diameter of the glass fiber is less than or equal to 30 mu m, the length-diameter ratio is 12: 1, has better insulativity, heat resistance, corrosion resistance and mechanical strength, and simultaneously, is also used as a framework of the water-based epoxy resin fire-resistant coating, and the raw material components of the fire-resistant coating are tightly combined together, thereby playing a good role in the structural stability of a fire-resistant layer.
The grain size of the nano silicon carbide is 50-80 nm; the silicon carbide is selected as the nanoscale silicon carbide, the wear resistance of the water-based epoxy resin fire-resistant coating is enhanced by adding the nanoscale silicon carbide, meanwhile, the fluidity of the water-based epoxy resin fire-resistant coating is increased, the surface tension of the material is reduced, and the nanoscale silicon carbide is added into the water-based epoxy resin fire-resistant coating, so that the surface properties of fire-resistant coating raw material particles can be subjected to nanocrystallization modification, and the fire-resistant coating raw material particles are uniformly dispersed; can adjust the mobility of the fire-resistant coating raw material particles, improve the dispersibility of the fire-resistant coating, shorten the dispersion time and further improve the caking property and the crack resistance of the water-based epoxy resin fire-resistant coating.
The particle size of the quartz sand is 60-80 meshes;
the particle size of the hollow glass beads is 60-80 μm, and the wall thickness is 1-1.2 μm; the hollow glass beads have the smallest specific surface area and low oil absorption rate, the use amount of other production components in the coating can be greatly reduced, and meanwhile, the surface is more resistant to chemical corrosion and has a reflection effect on light; so that the water-based epoxy resin fire-resistant paint coating has the effects of antifouling, corrosion resistance, ultraviolet resistance, yellowing resistance and scratch resistance. The hollow glass beads which are closely arranged contain thin gas, and the heat conductivity coefficient is low, so that the refractory coating has a very good heat insulation effect, and the hollow glass beads can effectively enhance the flowing and leveling property of the coating; the hollow glass beads contain gas which has better cold and heat shrinkage resistance, thereby enhancing the elasticity of the coating and greatly reducing the cracking and falling of the refractory coating caused by expansion under heat and contraction under cold.
