Embodiment 1

[0034] Add petroleum resin 30Kg, polyisobutylene 30Kg, antioxidant di-tert-butyl p-cresol 0.75Kg and [β-(3,5-di-tert-butyl 4-hydroxyl Phenyl) propionic acid] pentaerythritol ester 0.25Kg, light stabilizer TINVUN622 0.75Kg and CHIMASSORB944 0.25Kg. Heat up the oil bath to 180°C, keep warm for 30 minutes, and then add 15kg of amorphous polyolefin (APAO), 15kg of thermoplastic elastomer (SIS), and 15kg of ethylene-octene copolymer (POE), and wait until amorphous polyolefin (APAO), Turn on the kneader after the thermoplastic elastomer (SIS) and ethylene-octene copolymer (POE) are completely dissolved. The temperature is controlled at 180°C and stirred for 60 minutes, all the resins are melted and mixed into a uniform viscous liquid, and the stirring is stopped, and the hot-melt pressure-sensitive adhesive is prepared. Coated on a high-density polyethylene (HDPE) sheet, the thickness of the hot-melt pressure-sensitive adhesive is about 0.3mm. Determination of the adhesive propert...

Abstract

The invention discloses a hot-melt pressure-sensitive adhesive composition which is characterized by comprising the following components in percentage by weight: 20-30% of main body polymer, 30-40% of tackifier, 30-40% of plasticizer, 1-2% of antioxidant and 1-2% of light stabilizer. The invention also provides a preparation technique of the hot-melt pressure-sensitive adhesive composition. The hot-melt pressure-sensitive adhesive disclosed by the invention has the advantages of high cohesive force, favorable initial viscosity, high binding strength and high low-temperature flexibility, has favorable initial viscosity even in winter, can be used for binding solid materials, and especially has good effect for binding polyethylene materials.

Description

technical field [0001] The invention belongs to the field of polymer adhesives, and in particular relates to a hot-melt pressure-sensitive adhesive for polyethylene materials and a preparation method. Background technique [0002] Hot-melt pressure-sensitive adhesive is a new type of adhesive, which does not contain any solvent, has no pollution, has simple production process, low cost, convenient use and wide application. [0003] Hot-melt pressure-sensitive adhesives have dual properties of hot-melt and pressure-sensitive. It becomes liquid when heated to 130-200°C, and can be used by spraying, roller coating and scraping. When cooled to room temperature, it becomes solid again, and a certain pressure can produce good bonding effect. [0004] Traditional hot-melt pressure-sensitive adhesives are usually coated on paper, plastic films, fabrics or metal foils to make tapes or films, which are mainly used for various sealing, box sealing and paper packaging, label and label ...
