Abstract

The invention discloses water-based epoxy putty, relating to the technical field of coating production in the chemical industrial field. The water-based epoxy putty is prepared by mixing a component A, a component B and a component C, wherein the component A is a high-performance modified water-based epoxy emulsion; the component B is a mixed modified amine curing agent; the component C is mixed dry powder consisting of cement and quartz powder; and the weight ratio of the component A to the component B to the component C is (15-18):1:(15-18). The aging resistance, heat resistance, oil resistance, water resistance, precipitation resistance, medium resistance and electrical performance of the putty are enhanced; and the water-based epoxy putty has high physical and mechanical properties and high chemical resistance, and can be applied to the protection of a cement concrete fundamental plane.

Description

technical field [0001] The invention relates to the technical field of paint production in the field of chemical industry. Background technique [0002] At present, the main types of polymer cement putty in the domestic market are chloroprene emulsion, polyacrylate emulsion, ethylene-acetic acid, ethylene copolymer, polyurethane, epoxy emulsion and so on. Among them, the comprehensive performance indicators of water-based epoxy polymer cement mortar and putty are the most prominent. Water-based epoxy emulsions are usually produced by three methods: mechanical method, reverse forwarding and chemical acid method. [0003] Epoxy resins are difficult to form stable emulsions through mechanical emulsification. There are not many types of surfactants used to prepare epoxy emulsions. The more suitable emulsifier is an anionic surfactant containing a certain length of ethylene oxide chain members. This method is simple in process and requires less surfactant. The disadvantages are...
