Abstract

An epoxy resin modified VAE composite waterproof material and a preparation method thereof. The composite waterproof material is composed of a component A and a component B. A preparation method of the component A is as below: adding a vinyl acetate-ethylene copolymer emulsion into a material canister, then adding an epoxy resin emulsion and a defoaming agent, stirring, then adding aluminum hydroxide, phosphoric acid tris(2-chloroethyl) ester, talcum powder, a polytetrafluoroethylene fine powder, tetra [beta-(3,5-di-t-butyl-4-hydroxy phenyl) propionic acid] pentaerythritol ester, 2-(2H-benzo triazoles-2-yl)-6-dodecyl-4-methylphenol and water, and stirring to obtain the component A. A preparation method of the component B is as below: under the protection of nitrogen, adding tetraethylenepentamine into a reactor, dropwise adding ethylene glycol diglycidylether and butyl glycidol ether for a thermal reaction, then adding water to dilute and stirring to obtain the B component. The component A and the component B are stirred according to a part ratio of 100: 5-8 and applied; and after curing, a flame retardant antifouling self-cleaning composite waterproof material with a semi-interpenetrating network macro-molecular structure is obtained.
