Abstract

The invention relates to an adhesive, a foam double-sided adhesive, and preparation methods of the adhesive and the foam double-sided adhesive. The adhesive comprises, by weight, 20-30 parts of acrylate, 54-70 parts of a solvent, 0.1-0.4 part of a tackifier, 8-12 parts of a coupling agent, 6-8 parts of a cross-linking agent, 2.2-4 parts of an initiator, and 3-6 parts of a filler, wherein the acrylate is at least one selected from sec-butyl acrylate, tert-butyl acrylate and n-propyl acrylate, the tackifier is at least one selected from a C5 petroleum resin and a C9 petroleum resin, the couplingagent is at least one selected from isopropyl tri(dioctylphosphate)titanate and isopropyl triisostearoyl titanate, and the cross-linking agent is at least one selected from triethylenetetramine and N-methylol acrylamide. The foam double-sided adhesive is prepared from the adhesive and a PE foam substrate. According to the present invention, the foam double-sided adhesive has advantages of good water resistance, high adhesiveness, and the like.

Description

technical field [0001] The invention relates to the field of electronic adhesive products, in particular to an adhesive and foam double-sided adhesive tape and a preparation method thereof. Background technique [0002] Foam tape is made of foam as the base material, coated with solvent-based (or hot-melt) pressure-sensitive adhesive on one or both sides and then coated with release paper. It has excellent sealing performance, compression deformation resistance and long-lasting Excellent resilience can avoid gas release and atomization, and can ensure long-term shockproof protection for accessories. It can be used for the bonding of substrates such as curved surfaces, rough surfaces and smooth surfaces, and as time goes on, the contact area between the foam tape and the substrate to be bonded will become larger, and the bonding performance will not decrease too much; it has slow Rebound characteristics, deformation recovers slowly over time, good impact resistance; lower de...
