Abstract

The invention belongs to the field of pressure-sensitive adhesive tape production, and particularly discloses a preparation process of a tensile solvent-resistant pressure-sensitive adhesive tape. The preparation process comprises the following steps: using the combination of butyl acrylate and 2-ethylhexyl acrylate as soft monomers, methyl methacrylate as a hard monomer, epoxy resin as a modified monomer, acrylamide as an internal cross-linking agent and benzoyl peroxide as an initiator to prepare the pressure-sensitive adhesive which has better high-temperature resistance, and the high-temperature solvent resistance of the pressure-sensitive adhesive tape is improved; a base material of a three-layer composite structure is arranged, a PET thin film is used as a first film layer, a net face of a double-layer structure formed by weaving high stretch yarn is used as a second film layer, the first film layer is attached to the front face and the back face of the second film layer through an elastic adhesive, and thus the formed base material has ultrahigh elasticity and is good in tearing-resistant effect. The multi-stage curing and drying device is provided for curing and drying the pressure-sensitive adhesive tape, the drying temperature of each drying section and the stroke of each temperature section can be freely adjusted, and the multi-stage curing and drying device meets the drying requirements of various pressure-sensitive adhesives.

Description

technical field [0001] The invention relates to the field of pressure-sensitive adhesive tape production, in particular to a preparation process of a tensile-resistant and solvent-resistant pressure-sensitive adhesive tape. Background technique [0002] Pressure-sensitive tape is a special type of tape made by applying a special adhesive (pressure-sensitive adhesive) to a strip-shaped substrate. It consists of pressure-sensitive adhesive, base material, primer, back treatment agent, etc. Pressure sensitive adhesive is the most important component of pressure sensitive tape. Its role is to give the tape its pressure-sensitive adhesive properties. The main materials used as substrates are fabrics, plastic films, paper, etc. The primer is to increase the bond strength between the pressure sensitive adhesive and the substrate. When using, apply light pressure to make the adhesive tape adhere to the surface of the adherend. Widely used in packaging, electrical insulation, me...
