Abstract

The invention discloses a carbon fiber granule methacrylic resin/epoxy resin waterproof membrane composition and method. The composition is composed of a component A and a component B, wherein the component A is composed of modified methyl-methacrylate (MMA) resin, a modified low-viscosity epoxy phenolic resin, superfine carbon fiber granules, titanium white, carbon black, ceramic powder, a polyacrylamide dispersing agent, an organosilicon flexibilizer, a water-resistant cyanoacrylate connector and a polyethylene wax anti-settling agent, totaling 100 parts by mass. The component B is composed of ethylenediamine, alicyclic amine, isocyanate and a polyamide accelerator, totaling 20 parts by mass. The composition has higher strength and higher flexibility than the past common MMA resin. By adding the superfine carbon fiber granules and special-type epoxy resin, the spray-type elastic waterproof membrane fused with the high-performance MMA resin can be quickly cured and formed at normal temperature or low temperature, is applicable to the ambient temperature of -40 to 1000 DEG C, and has excellent wear resistance and corrosion resistance.

Description

technical field [0001] The invention relates to a composition and a method, in particular to a carbon fiber particle methacrylic resin epoxy resin waterproof film composition and a preparation method. Background technique [0002] People generally apply a layer of waterproof membrane on the surface of steel box girders, concrete bridge decks, steel structure bridge decks, bridge piers, pipes, industrial floors, roofs, etc., to resist corrosion, wear and other natural conditions. At present, waterproof coatings containing methyl methacrylate resin are generally used on the market, but the strength of ordinary methyl methacrylate resin waterproof coatings is not high enough, the flexibility is not strong, and the use conditions are also limited by the surrounding environment and temperature. Sex, its production method is loaded down with trivial details, time-consuming and laborious. Contents of the invention [0003] In order to solve the shortcomings of the above-mentione...
