Abstract

The invention discloses a special epoxy resin adhesive for a stone material. The special epoxy resin adhesive is prepared from the following raw materials in parts by weight: 100 parts of epoxy resin, 20 to 35 parts of amino-terminated liquid nitrile butadiene rubber, 20 to 50 parts of dicyandiamide, 2 to 5 parts of a curing accelerant, 3 to 10 parts of nano calcium carbonate, 2 to 10 parts of kaolin, 1 to 5 parts of fly ash and 5 to 12 parts of nano silicon dioxide. The special epoxy resin adhesive for the stone material, provided by the invention, has high binding force, good strength after curing, good impacting toughness and excellent weather-resisting performance.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to an epoxy resin adhesive special for stone. Background technique [0002] At present, with the progress of society, people have higher and higher requirements for building decoration, and various natural stone materials and various exquisitely crafted ceramic finishes emerge in an endless stream. People commonly use stone materials such as marble, granite, and ceramic finishes such as ceramic tiles, glazed tiles, mosaics, etc., and the adhesives for pasting these decorative fabrics are mainly cement mortar. The cost is higher, and the separation is serious, and the construction is very inconvenient, especially the sticking of the top plate is very difficult, labor-intensive and time-consuming. [0003] Due to its good mechanical properties, electrical properties and chemical corrosion resistance, epoxy resin is widely used in surface coatings, electronic and electrical componen...
