Abstract

The invention discloses a novel easily-peeled pressure-sensitive adhesive. The novel easily-peeled pressure-sensitive adhesive comprises, by weight, 2 to 10 parts of methyl acrylate, 1 to 5 parts of butyl acrylate, 3 to 15 parts of vinyl acetate, 10 to 30 parts of 2-ethylhexyl acrylate, 30 to 40 parts of 2-ethylhexyl methacrylate, 5 to 10 parts of glycerol, 3 to 7 parts of a cross-linking agent, 30 to 50 parts of an organic solvent and 5 to 10 parts of rosin. The novel easily-peeled pressure-sensitive adhesive is mainly used as a bonding layer between two films, can be easily peeled from a base, has good transparency and no residues, can be processed easily and is convenient for use. When a film with the novel easily-peeled pressure-sensitive adhesive is pasted on a base and especially on clothes and caps, the top layer and the bottom layer can be separated easily and the bottom layer is still pasted on the base. Therefore, the novel easily-peeled pressure-sensitive adhesive can be used for various double-layer film pasting.

Description

technical field [0001] The invention relates to a pressure-sensitive adhesive, in particular to an easy-peelable pressure-sensitive adhesive applied between layers of a double-layer film. Background technique [0002] In recent years, with the expansion of demand for packaging, decoration, office supplies and various films, people's demand for pressure-sensitive adhesives is also increasing. Among the pressure-sensitive adhesives used in the production of various pressure-sensitive adhesive products, acrylic emulsion pressure-sensitive adhesives account for about 50%. It can be seen that acrylic emulsion pressure-sensitive adhesives occupy a very important position in the industry. This is because it has the advantages of non-toxicity, no three-waste pollution, no fire hazard, and low cost. In 1998, the output of BOPP acrylic pressure-sensitive packaging tape reached 1.2 billion m 2 . Acrylic pressure-sensitive tapes, double-sided tapes, protective tapes, masking tapes, f...
