Special heat-resisting and flame-retarding epoxy resin adhesive for stone material

Abstract

The invention discloses a special heat-resisting and flame-retarding epoxy resin adhesive for a stone material. The special heat-resisting and flame-retarding epoxy resin adhesive is prepared from the following raw materials in parts by weight: 70 to 85 parts of modified epoxy resin, 5 to 20 parts of polyamide acid, 3 to 15 parts of 2,6-dimethyl-1,4-phenylate, 5 to 12 parts of an acrylonitrile-styrene-acrylate copolymer, 5 to 20 parts of polyethersulfone, 2 to 10 parts of hydroxyl-terminated liquid nitrile butadiene rubber, 2 to 12 parts of dicyandiamide, 3 to 12 parts of benzoxazine, 2 to 10 parts of linear phenol-formaldehyde resin, 1 to 5 parts of liquid methyl tetrahydrophthalic anhydride, 1 to 5 parts of a curing accelerant, 2 to 10 parts of nano aluminum hydroxide, 2 to 5 parts of silicon micro-powder, 5 to 15 parts of ferroferric oxide, 2 to 8 parts of nano titanium dioxide and 2 to 11 parts of hexagonal boron nitride. The special heat-resisting and flame-retarding epoxy resin adhesive for the stone material, provided by the invention, has long storage time, high binding performance on a cured material, good impacting toughness, excellent anti-stripping effect and excellent heat-resisting performance and flame-retarding performance.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a special heat-resistant and flame-retardant epoxy resin adhesive 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, ...
