Problems solved by technology

Adding an external cross-linking agent not only increases the production process, but also because the pot life of the emulsion pressure-sensitive adhesive after adding the cross-linking agent is usually less than 10 hours, the prepared unused pressure-sensitive adhesive and the residual pressure-sensitive adhesive in the glue tank not only cause waste and pollute the environment

Abstract

The invention provides a mono-component emulsion pressure-sensitive adhesive for a surface protective film and a preparation method and application thereof. The mono-component emulsion pressure-sensitive adhesive for the surface protective film is a polyacrylate emulsion synthesized from butyl acrylate, vinyl acetate, acrylic acid, N-methylolacrylamide and allyl methacrylate by using a pre-emulsification semi-continuous polymerization process. The mono-component emulsion pressure-sensitive adhesive provided by the invention overcomes the disadvantage that a conventional pressure-sensitive adhesive for a protective film cannot be used without addition of a cross-linking agent; and the surface protective film prepared from the mono-component emulsion pressure-sensitive adhesive provided by the invention has moderate peeling strength and good adhesion on a PVC section bar, an alumina section bar and sheets of household electrical appliances, leaves no residual adhesive and spots after peeling and does not contaminate the PVC section bar, the alumina section bar and the sheets of household electrical appliances.

Description

technical field [0001] The invention relates to a single-component latex pressure-sensitive adhesive for surface protection film, and its application on the protective film of household appliances, the protective film of PVC profile and the protective film of aluminum oxide profile. Background technique [0002] With the rapid development of the national economy, building profiles and home appliances are used more and more widely in production and life. During the production, storage and transportation of PVC profiles and alumina profiles for construction and household appliances, the outer surface needs to be protected to prevent harmful gases, microbial corrosion, dust pollution, or avoid scratches caused by mechanical scratches, etc. . One of the most commonly used methods is now on the surface of the object to be protected, a layer of protective film (i.e. surface protective film) pasted, after finishing handling such as transportation, storage, processing and assemblin...
