Problems solved by technology

(1) Natural latex has poor affinity to denser paper and paper containing printing ink, and has almost no affinity with paint, metal, plastic film and other substrates. Although latex is applied to products made of the above substrates However, when peeling off after self-adhesive, the adhesive film is easy to detach from the adhered article, and the adhesive article will be opened as soon as it is peeled off, which limits the wide application of natural rubber latex; (2) natural latex after drying with time Prolonged, the self-adhesive performance degrades, and there is almost no self-adhesiveness after one month, which requires that the products coated with self-adhesive must be applied within a certain period of time

Abstract

The invention discloses an environment-protective multifunctional self-viscose and making method, which comprises the following parts: natural aqueous latex, VAE emulsion, pressure-sensitive emulsion of acrylic acid, phthalandione dioctyl, phthalandione dibutyl ester, aqueous defoamer RE-3921, antiager DNP.

Description

technical field [0001] The invention belongs to the technical field of adhesives, in particular to an environment-friendly multifunctional self-adhesive and a preparation method thereof. Background technique [0002] At present, the main component of self-adhesive used in the market is water-based natural latex. Although natural latex has certain self-adhesiveness, anti-corrosion, waterproof and film transparency, it also has many deficiencies. (1) Natural latex has poor affinity to denser paper and paper containing printing ink, and has almost no affinity with paint, metal, plastic film and other substrates. Although latex is applied to products made of the above substrates However, when peeling off after self-adhesive, the adhesive film is easy to detach from the adhered article, and the adhesive article will be opened as soon as it is peeled off, which limits the wide application of natural rubber latex; (2) natural latex after drying with time Prolonged, the self-adhesi...
