Problems solved by technology

In aerospace, transportation, medical and industrial equipment, automobiles, home appliances, and electronics markets, it can be used for bonding nameplates and labels; currently, the general OPP tape on the market is slightly yellowish, in order to meet some markets The needs, especially in Southeast Asia, need some white OPP tapes. For this reason, many OPP tapes add chemical pigments to the original adhesive to make the adhesive white, but this increases the research and development costs. The synthesis process is complicated. For example, the patent CN101805577A discloses a transparent epoxy resin encapsulation adhesive. A transparent blue-violet dye paste is added to the glue, thereby neutralizing the yellow color produced by the epoxy resin.

Abstract

The invention discloses an adhesive for a white and transparent OPP (Oriented Polypropylene) adhesive tape and a processing technology thereof. The adhesive is mainly prepared from the following raw materials: butyl acrylate, isooctyl acrylate, acrylic acid, hydroxyethyl acrylate, dodecanethiol, methyl methacrylate, an emulsifier, a wetting agent, a de-foaming agent, an initiator and a preservative. According to the adhesive disclosed by the invention, other raw materials do not need to be added and the adhesive tape can have a white and transparent effect; the research and development cost isreduced; meanwhile, a synthesis technology is simplified.
