Embodiment 1

[0028] Weigh 27g and 0.2g of the required plasticizer E and antioxidant F1010 respectively, weigh 50% of the required amount of specially customized partially hydrogenated modified petroleum resin C and 27.8g of all ordinary hydrogenated petroleum resin D, add to Reactor; heat the material to 130°C, stabilize the jacket temperature at 210°C, then add 5g and 20g of star-shaped SBS (customized) polymer A and linear SIS polymer B to the reactor, stir for 2 hours, and stabilize The temperature of the material is 155.5°C; test whether the material is evenly mixed and fully melted, and if it is fully melted, add the remaining 50% of the specially customized partially hydrogenated modified petroleum resin C, fully stir for 30 minutes and then recirculate for 10 minutes.

Abstract

The invention discloses a low-size high-viscous-force hot-melt pressure-sensitive backing adhesive. The backing adhesive is prepared from the ingredients in percentage by weight: 0% to 20% of star-shaped polymer A, 0% to 20% of polymer B, 15% to 55% of special tackifying resin, 10% to 40% of plasticizer and 0.1% to 2% of antioxidant. According to the low-size high-viscous-force hot-melt pressure-sensitive backing adhesive, all-hydrogenated petroleum resin and star-shaped SBS are replaced with partially-hydrogenated petroleum resin, and the partially-hydrogenated petroleum resin is mixed with linear SIS; in addition, by a reasonable ingredient formula and a preparation method, the effects that the size of the backing adhesive is remarkably lowered, the thickness of the backing adhesive is reduced, and meanwhile, the viscous force of the hot-melt pressure-sensitive backing adhesive is greater are achieved.

Description

technical field [0001] The invention belongs to the field of adhesives, in particular to a hot-melt pressure-sensitive adhesive back glue used in the industry of disposable hygiene products. Background technique [0002] Hot melt adhesive is a kind of plastic adhesive. Its physical state changes with temperature within a certain temperature range, but its chemical properties remain unchanged. It is non-toxic and tasteless, and is an environmentally friendly chemical product; A type of adhesive that is sensitive and can be bonded to the adherend with a little finger pressure. Hot-melt pressure-sensitive adhesives have the dual characteristics of hot-melt adhesives and pressure-sensitive adhesives, and are the third-generation pressure-sensitive adhesive products after solvent-based and emulsion-based pressure-sensitive adhesives. Hot-melt pressure-sensitive adhesive has become one of the hot research materials in various countries because of its solvent-free, clean and envir...
