Technical Field
The invention relates to the technical field of acrylate structural adhesives, in particular to an acrylate epoxy resin hybridization adhesive.
Background
In the folding process of the four-door two-cover (car door, engine cover and trunk cover) of the car, single-component epoxy glue is generally used as folding glue, the edges of the cover plate are folded after being glued, and the glue is solidified in the subsequent electrophoresis and baking processes, so that the inner plate and the outer plate are bonded and fixed. In the transferring process after edge folding, the position of the inner plate and the outer plate cannot be kept relatively fixed because the edge folding glue is not solidified, and the problem of unstable size can be generated in the transferring and electrophoresis processes. The problem of dimensional instability is more pronounced when the coefficients of thermal expansion of the inner and outer panels of the hood are different. The bi-component acrylic ester adhesive can be cured at normal temperature, but has the problems of overlarge curing shrinkage, low high-temperature strength and the like, and cannot be used as edge folding adhesive.
Based on the above, it is important to provide an adhesive which has the advantages of normal temperature curing, high temperature strength, low curing shrinkage and capability of meeting the requirements of the flanging process.

Compared with the prior art, the invention has the beneficial effects that:
The invention prepares the acrylic epoxy resin hybrid adhesive by an initiator prepared from bisphenol A epoxy resin, a diluent, a filler, an oxidant and color paste according to a specific proportion, and an accelerator prepared from specific acrylate monomers, nitrile rubber, liquid rubber, a complexing agent, a stabilizer, a reducing agent and epoxy curing agent organic urea according to a specific proportion, wherein the normal-temperature tensile shear strength (CF) is more than or equal to 20MPa, the high-temperature (180 ℃) tensile shear strength (CF) is more than or equal to 2.3MPa, the T peel strength (CF) is more than or equal to 10N/mm, the elongation at break is more than or equal to 40%, the curing volume shrinkage rate is less than or equal to 7%, and the folding process requirement can be met.
