Abstract

The invention discloses a novel environmental-friendly middle- and low- temperature pressure-sensitive adhesive used for hygienic products and a preparing method thereof. The objective of the invention is to provide the novel environmental-friendly middle- and low- temperature pressure-sensitive adhesive with high toughness, long adhesiveness maintaining time and stable adhesiveness used for the hygienic products and the preparing method thereof. The pressure-sensitive adhesive comprises following components by weight: 12-25 parts of high-pressure hydrogenated naphthenic base rubber oil, 15-30 parts of star styrene-isoprene-styrene block copolymer (SIS), 5-15 parts of hydrogenated styrene-isoprene-styrene block copolymer (SEPS), 20-30 parts of water-white C5 / C9 resin, 10-25 parts of pentaerythritol ester of rosin, 12-20 parts of terpene resin, and 0.3 part of an antioxidant. The pressure-sensitive adhesive has advantages of stable colloid propeties, good weather fastness, long adhesiveness maintaining time, good high-temperature resistance, and the like.

Description

technical field [0001] The invention relates to a pressure-sensitive adhesive, in particular to a novel pressure-sensitive adhesive for environment-friendly medium and low temperature sanitary products and a preparation method thereof. Background technique [0002] Pressure sensitive adhesive is an adhesive that is sensitive to pressure. Existing pressure-sensitive adhesives have poor toughness, unstable adhesive properties, poor weather resistance, short viscosity retention time, dark product color, and poor high-temperature resistance. Contents of the invention [0003] The object of the present invention is to provide a new environment-friendly pressure-sensitive adhesive for medium and low temperature hygiene products with good toughness, long stick life and stable glue and its preparation method in order to solve the shortcomings of the above-mentioned technologies. [0004] In order to achieve the above-mentioned purpose, a novel environment-friendly low-temperature...
