Embodiment Construction

[0129] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0130] The following components of the acrylate structural adhesive of the present invention are analyzed:

[0131] (1) (meth)acrylate monomer or oligomer

[0132](Meth) acrylate monomers or oligomers are the main components of acrylate structural adhesives, while methyl methacrylate is the main active monomer of acrylic adhesives, and the mass fraction is often as high as 50% to 70%. . Although its boiling point is only 100°C, it has a strong odor, strong volatility, and is seriously irritating to the human body. However, due to its excellent performance and reasonable cost, most acrylic structural adhesives currently have no way to completely remove this monomer. In addition, the glass transition temperature of the homopolymer using me...

Abstract

The invention discloses a high-elasticity room temperature rapidly cured acrylic ester structure adhesive and a preparation method thereof. The acrylic ester structure adhesive consists of a component A and a component B, which comprise an oxidizing agent and a reducing agent which are polymerized through an initiating system, a (methyl) acrylic ester monomer or a (methyl) acrylic ester oligomer, (methyl) acrylic acid, (methyl) acrylic acid phosphate ester, a toughening and thickening agent, a stabilizing agent and other auxiliaries, and possibly comprise a plasticizing agent and epoxy resin. The component A and the component B are combined according to a certain ratio. The acrylic ester structure adhesive disclosed by the invention is rapid in room temperature curing speed, high in elongation rate, good in elasticity and wide in adhered base material.

Description

technical field [0001] The invention relates to a two-component adhesive, especially a high-elastic room-temperature fast-curing acrylate structural adhesive and a preparation method thereof, which are widely used in the fields of home appliances, engineering, automobiles, aviation, machinery, electronics, elevators, rail transit and the like. Background technique [0002] The second-generation acrylate structural adhesive, referred to as SGA, is a fully reactive two-component adhesive. Because it has many advantages: fast curing at room temperature and adjustable curing speed; two-component and no strict metering, easy to use and conducive to automation; no strict surface treatment, and oil surface adhesion; a wide range of bonding materials; Conducive to the assembly of profiled materials; high mechanical strength, wide adjustment range, etc. Therefore, only 20 years since its appearance in the mid-1970s, SGA has developed rapidly. [0003] But at present, most SGAs are ...
