Embodiment Construction

[0074] 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 specific drawings and embodiments.

[0075] The invention relates to an acrylic structural adhesive with ultra-high bonding strength, wide mixing ratio, fast curing at room temperature and extensive bonding performance that can be applied to multiple industries. It is completed through the following technical scheme. The new type of adhesive A wide range of ultra-high-strength acrylic structural adhesives include the following ingredients:

[0076] (1) (meth)acrylate monomer or oligomer

[0077] (Meth) acrylate monomer or oligomer is the main component of acrylate structural adhesives, while methyl methacrylate is the main active monomer of acrylic adhesives, and the mass number is often as high as 50%~70% . Although its boiling point is only 100 ℃, it has a strong odor, strong volatility, ...

Abstract

The invention provides an ultrahigh-strength acrylate structural adhesive with wide adhesion and a preparation method of the ultrahigh-strength acrylate structural adhesive. The acrylate structural adhesive consists of an initiator (component A) and an accelerant (component B) according to a ratio of 1:1, wherein the initiator (component A) comprises the following components: a (methyl)acrylate type monomer or oligomer, a toughening tackifier, an oxidant for an oxidation-reduction system, a stabilizer and other auxiliary agents; and the accelerant (component B) comprises the following components: a (methyl)acrylate type monomer or oligomer, (methyl)acrylic acid, (methyl)acrylic acid phosphate ester, a toughening tackifier, a reducer for an oxidation-reduction system, a stabilizer and other auxiliary agents. The acrylate structural adhesive provided by the invention can be solidified quickly at room temperature, is wide in adhesive property, and has ultrahigh adhesion strength and a wider mixing ratio range; and ultrahigh strength adhesion of various materials can be realized while the adhesive is quickly solidified at room temperature.

Description

technical field [0001] The invention relates to an ultra-high-strength acrylic structural adhesive and a preparation method thereof, which can be widely used in many fields such as home appliances, engineering, automobiles, aviation, machinery, electronics, sports equipment, etc. High structural adhesive products. Background technique [0002] Acrylic Structural Adhesive is a fully reactive two-component adhesive primarily used for rapid positioning of metals, plastics and composites, such as the assembly and repair of automobiles, trucks, buses, boats and other structural products. Up to now, the performance of acrylic structural adhesive products has been greatly improved, and it has many advantages: fast curing at room temperature and adjustable curing speed; two-component and no strict metering, easy to use, conducive to automation; no need Strict surface treatment, with oil surface bonding; a wide range of bonding materials, which is conducive to the assembly of profil...
