Abstract
The invention relates to a water-based acrylic pressure-sensitive adhesive composition which can be coated on a polyvinyl chloride pressure-sensitive adhesive tape, is used for improving the harm of the traditional solvent-based pressure-sensitive adhesive to human bodies, environment and VOCs, is an environment-friendly pressure-sensitive adhesive, has the solid content of about 50-55 percent, and is relatively friendly to the human bodies and natural environment. The water-based acrylic pressure-sensitive adhesive takes water as a solvent, does not contain nonyl phenol, and has much higher degree of environmental friendliness to human bodies than solvent-based rubber; when the adhesive tape is used on a polyvinyl chloride pressure-sensitive adhesive tape, the transfer of a small molecular plasticizer to the pressure-sensitive adhesive after curing can be effectively inhibited, the serious decline of relevant physical properties is avoided, and the adhesive tape can keep excellent performance.
Description
Technical Field
The invention relates to a water-based acrylic pressure-sensitive adhesive coated on a polyvinyl chloride pressure-sensitive adhesive tape, which is particularly assisted by using a water-based environment-friendly primer and a water-based environment-friendly pressure-sensitive adhesive which need to use related auxiliary agents.

In the process of manufacturing the polyvinyl chloride pressure sensitive adhesive tape, Nonylphenol (NP) which pollutes the environment, also called nonylphenol, is used as a main raw material, and although nonylphenol is often used as one of raw materials for manufacturing Nonylphenol Polyoxyethylene Ethers (NPEO) due to the characteristics of high viscosity, high boiling point and low vapor pressure, in recent years, due to the fact that the nonylphenol is similar to estrogen (estrogen) in chemical structure and is considered to be one of environment hormones, the environmental awareness is raised, and the long-term contact is suspicious, so that the pollution of organisms and the environment is great, and therefore, the problem of the environmental hormones is solved.
Because the surface energy of the polyvinyl chloride film is high, if the rubber or the acrylic pressure-sensitive adhesive is directly coated, the adhesive will be degummed, so a layer of primer is coated before the aqueous acrylic glue is coated to be used as a medium for combining the polyvinyl chloride film and the rubber or the acrylic pressure-sensitive adhesive, so as to improve the adherence (Anchorage) of the pressure-sensitive adhesive to the polyvinyl chloride film.
The surface glue of the traditional polyvinyl chloride pressure-sensitive adhesive tape is mostly solvent type rubber pressure-sensitive adhesive, the solid content is about 15-35%, and the proportion of the solvent is quite high; volatile Organic Compounds (VOCs) are easy to damage in the coating process, which is not only harmful to human health, but also pollutes the surrounding natural environment.
