Abstract

The invention relates to epoxy grout which comprises the following components: epoxy resin, filler and pigment, and is characterized by further comprising toughening resin and a toughening curing agent, wherein the toughening curing agent is polyether arylamine. According to the epoxy grout, polyether arylamine is adopted as the toughening curing agent in a breakthrough manner, and a precise formula is adopted, so as to achieve the effect that the epoxy grout has high temperature difference resistance and high adhesive force performance; besides, the adhesive force of the epoxy grout after curing reaches 9 Mpa, the cold and heat resisting cycle temperature reaches to minus 30 to 80 DEG C, and the elongation reaches 8%.

Description

technical field [0001] An epoxy resin-based adhesive, in particular to an epoxy mastic. Background technique [0002] The anticorrosion of the running water ditches, cracks, and concave and convex parts of the ship was first laid with cement, which was prone to cracking and falling off, which made the seawater more silted up, which aggravated the corrosion of steel and shortened the service life; then it was laid with epoxy and amine curing agent The material encountered the same problem, it is brittle and easy to crack, and it also has the problems of easy cracking and falling off when casting 5-10cm thick, and poor resistance to cold and heat. [0003] Epoxy resin cement is based on epoxy resin, together with a series of additives such as accelerators, after mixing and curing, it forms a high-strength, high-adhesive consolidated body. It has stable chemical properties, good corrosion resistance and weather resistance, high compressive strength and is not limited by struct...
