Method and its application.
Background technology
Traditional epoxy coating must use organic solvent in use, therefore be waved containing organic in its system
Object is sent out, not only environment can be caused seriously to pollute, and also have great threat to health.Aqueous epoxide resin paint subtracts
Lack it to injure caused by environment and human body, but the caking property and mechanical performance of existing aqueous epoxide resin paint can drop
It is low so that coating is easy cracking and falls off, to the use of the aqueous epoxide resin paint of limitation.
Invention content
The present invention is for a kind of aqueous epoxy resins fireproof coating of problem of the prior art offer, preparation method and its answers
With solving that not high aqueous epoxy resins fireproof coating mechanical strength in the prior art, bad adhesion, impact resistance be poor, cracking resistance
Property difference problem.
In order to solve the above-mentioned technical problem, the present invention adopts the following technical scheme that：
One of the objects of the present invention is to provide a kind of aqueous epoxy resins fireproof coatings, including following component：
The preparation method of the Acryrylic acid modified bisphenol A epoxy resin includes the following steps：
