Abstract

The invention discloses flame-retardant epoxy grout used for joint filling and leakage stopping. The grout is composed of a component A and a component B which are different in color. The component A comprises, by mass, 80-100 parts of epoxy resin, 4-15 parts of diluent, 50-100 parts of talcum powder, 20-50 parts of aluminum hydroxide, 5-10 parts of gas-phase white carbon black, 50-100 parts of silica powder and 0.1-3 parts of pigment. The component B comprises 40-100 parts of epoxy resin curing agents, 20-50 parts of liquid flame retardant, 50-100 parts of talcum powder, 20-50 parts of aluminum hydroxide, 5-10 parts of gas-phase white carbon black, 50-100 parts of silica powder and 0.1-3 parts of pigment. The grout is easy to prepare and convenient to construct, can be directly and manually kneaded or stirred through a machine, is moderate in operation period, quick in curing, high in strength after curing and good in toughness, and has a good flame-retardant effect.

Description

technical field [0001] The invention relates to a caulking and leak-stopping material, in particular to a flame-retardant epoxy mastic for caulking and leak-stopping. Background technique [0002] The improvement of flame retardant requirements in my country's construction, machinery and other industries has posed greater challenges for developers to develop new and efficient flame retardant products. In addition to striving for perfection in the early stage of building construction or machinery manufacturing, it is also necessary to take timely remedial measures when the product breaks or is damaged in the later stage. The existing caulking and leak-stopping materials have low strength, poor toughness, easy cracking, and poor corrosion resistance, and most of them are inconvenient to construct, complicated to operate, and have unsatisfactory flame-retardant effects. Therefore, the filling material with excellent performance is used for repairing, so as to meet the requirem...
