Description
Technical field
The invention belongs to the bi-component acrylic ester structure adhesive technical field.Be specifically related to a kind of acrylic ester adhesive that is used for spot-welding technology.
Background technology
Because fast type acrylic ester structure adhesive admittedly has distinguishing features such as room temperature fast-curing, intensity is high, but the good toughness pasta is bonding, flexibility is strong, technology is easy, the structure that therefore is widely used in industries such as aerospace, aviation, automobile, machinery, naval vessel, electronics, electrical equipment, instrument, building, furniture, toy, rail vehicle, civil engineering work, industrial art is bonding, smallclothes assembling, big part assembling, emergent reparation, impervious leakage-stopping, nameplate stickup etc.Also obtaining application preferably aspect sophisticated technology and the high-tech.
In general, acrylic ester adhesive belongs to inflammable substance, and especially catching fire very easily when spot welding brings very big trouble to spot-welding technology.In order to adapt to spot-welding technology, to develop and a kind ofly can keep the acrylic ester adhesive characteristics, the acrylic ester adhesive that can adapt to spot-welding technology again is just very necessary.
Summary of the invention
The present invention is directed to above-mentioned weak point and a kind of acrylic ester adhesive that is used for spot-welding technology is provided.
The technical solution of acrylate structural adhesive of the present invention is: a kind of acrylic ester adhesive that is used for spot-welding technology, belong to bi-component acrylic ester structure glue, and host and solidifying agent proportioning are 1: 1, it is characterized in that:
(1) host component: 42% ~ 85%Wt contains the acrylate monomer of 1 vinyl at least, 0% ~ 12%Wt methylacrylic acid, 0% ~ 30%Wt elastomerics; 0.01% ~ 1%Wt stablizer; 0% ~ 30%Wt toughened resin, 0% ~ 20%Wt fire retardant, 0.5% ~ 8%Wt superoxide;
(2) curing agent component: 40% ~ 90%Wt contains the acrylate monomer of 1 vinyl at least, 0% ~ 23%Wt elastomerics, 0% ~ 20%Wt methylacrylic acid, 1% ~ 10%Wt promotor, 0% ~ 30%Wt toughened resin, 0% ~ 20%Wt fire retardant;
(3) have at least a component to contain elastomerics in host and the solidifying agent, elastomer content is 10% ~ 30%Wt of place component.
The described acrylate monomer that contains 1 vinyl at least of technical solution is monomethacrylates monomer, dimethacrylate monomer, many methacrylate monomers or its mixture among the present invention.
The described acrylate monomer that contains 1 vinyl at least of technical solution monomethacrylates monomer preferably among the present invention.
The described monomethacrylates monomer of the technical solution mixture of TEB 3K and methylacrylic acid hydroxyl ester preferably among the present invention.
The described TEB 3K of technical solution and the ratio of methylacrylic acid hydroxyl ester are 2: 1 to 1: 5 among the present invention.
The ratio of said TEB 3K of technical solution and methylacrylic acid hydroxyl ester is preferably 3: 2 to 1: 3 among the present invention.
