Epoxy putty

Abstract

The invention relates to providing an epoxy putty. The epoxy putty comprises quartz powder, fly ash, calcite, polyethylene glycol, organosilane powder and low molecular resin; wherein, relative to 1 part by weight of the quartz powder, The content of fly ash is 0.5-1.5 parts by weight, the consumption of calcite is 0.5-0.8 parts by weight, the consumption of polyethylene glycol is 0.2-0.8 parts by weight, the consumption of organosilane powder is 0.5-1.0 parts by weight, low molecular weight The amount of resin used is 0.2-0.5 parts by weight. The epoxy putty of the invention has good physical and mechanical properties, high chemical resistance and stability, strengthens cement floors, fully penetrates, increases ground flatness and compressive strength, has a simple preparation method, high operability, and is green Environmental protection has great economic and social value.

Description

technical field

[0001] The invention relates to the construction field, in particular to an epoxy putty. 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 The particle siz...
