Abstract

The present invention relates to the field of composite materials, and concretely relates to a high-efficient epoxy resin adhesive and a preparation method and applications thereof. The high-efficient epoxy resin adhesive of the present invention comprises the following components: 60 to 100 parts by weight of epoxy resin, 15 to 60 parts by weight of a curing agent, 10 to 40 parts by weight of plasticizer, 0.5 to 5 parts by weight of a curing accelerator, and 10 to 30 parts by weight of a filler. The adhesive of the present invention has good adhesive performance, strong mechanical properties, and small shrinkage after curing, so the adhesive is especially suitable to be used as a binder for composite sheets in vehicles.

Description

technical field [0001] The invention relates to the field of composite materials, in particular to a high-efficiency epoxy resin adhesive suitable for vehicle composite material panels and a preparation method thereof. Background technique [0002] Adhesive is a substance or material that has excellent bonding properties, and under certain conditions, enables the material to be bonded to interact with molecules (atoms) in the interface (surface) layer to connect the surfaces of two solid materials together. [0003] As a high-performance resin, epoxy resin has excellent bonding properties, mechanical properties, electrical insulation, chemical stability and low shrinkage, easy processing and molding, and low cost. It is widely used in adhesives, coatings, etc. , composite materials and other industries. [0004] With the continuous development of polymer materials, single-component epoxy resin adhesives can no longer meet the high requirements for adhesives. Especially in ...
