Isooctyl acrylate waterproof insulating adhesive tape and preparation method thereof

Abstract

The invention discloses an isooctyl acrylate waterproof insulating adhesive tape and a preparation method thereof. The preparation method comprises the following steps of raw material preparation, mixing and stirring processing, distillation processing, dealcoholization processing, waste liquid treatment, coating preparation and storage treatment. The method specifically comprises: firstly, mixing and stirring acrylic acid, isooctanol, a catalyst and a polymerization inhibitor according to a preset proportion to obtain a reaction stock solution, distilling the reaction stock solution to obtain crude 2-ethylhexyl acrylate, dealcoholizing the crude 2-ethylhexyl acrylate to obtain a finished product 2-ethylhexyl acrylate, preparing glue from the finished product 2-ethylhexyl acrylate, coating the glue on bottom paper, coating the glue to prepare an adhesive tape finished product, neutralizing waste liquid generated in the preparation process by using an alkaline aqueous solution. The adhesive tape can be harmlessly discharged, soil pollution is avoided, the adhesive tape has good waterproof and insulating effects by adding the 2-ethylhexyl acrylate raw material into the adhesive tape, meanwhile, the preparation efficiency is higher, and production is convenient.

Description

technical field [0001] The invention relates to the field of adhesive tapes, in particular to an isooctyl acrylate waterproof insulating adhesive tape and a preparation method thereof. Background technique [0002] Isooctyl acrylate is a chemical substance with the molecular formula C11H20O2. It is mainly used as a soft monomer for the manufacture of acrylate solvent-based and emulsion-type pressure-sensitive adhesives. It is also used in the manufacture of coatings, plastic modifiers, papermaking and leather processing aids, and fabric finishing agents. It has excellent performance in making adhesive tapes. The waterproof and insulating effect of the commonly used isooctyl acrylate tape is simple to prepare, not only the waste liquid is difficult to handle during the preparation, thereby polluting the soil, but also the quality of the raw materials obtained is low, which affects the waterproof and insulating performance of the tape.
