Abstract

The invention provides a structural adhesive for an automobile and a preparation method of the structural adhesive, and relates to the field of glue preparation. The structural adhesive for the automobile is prepared from the following components (in parts by weight): 50-80 parts of an acrylate composition, 3-8 parts of a photoinitiator, 1-5 parts of a coupling agent, 10-20 parts of a filler and 1-2 parts of a dispersing agent. The preparation method of the structural adhesive for the automobile comprises the steps of primary stirring, secondary stirring, tertiary stirring, filling and packaging. By reasonably selecting the materials, the prepared product is stable and is suitable for the production requirements of automobiles, and meanwhile, the stirring efficiency can be improved by adopting a dilution mode in the production of the product.

Description

Technical field [0001] The present invention relates to the technical field of glue preparation, and is specifically a structural adhesive and a preparation method thereof thereof. Background technique [0002] Water is an intermediate that connects two materials, and there is more water generations, which belongs to fine chemicals, a wide variety, mainly based on stickiness, physical form, hardening method, and adherored material. Common instantaneous glue (common -1203 transient dry glue-cyanoacrylate is a strong instantaneous receiving agent), epoxy resin bonding, anaerobic glue, UV glue (UV light curing), hot melt Glue, pressure sensitive glue, latex, etc. Glue is a substance that is capable of bonding two objects. Glue does not exist independently, it must be coated between two objects to play a bonding effect. The chemical composition in glue is in aqueous environments. The high molecular bodies in glue (ethylene acetate in white gum are a petroleum derivative) are circular...
