Embodiment 1

[0017] At room temperature, 100 g of maleic anhydride and 4 g of 2,5-dimethyl-2,5-di-tert-butylperoxyhexane were dissolved in 100 g of acetone. Mix 3kg of high-density polyethylene and 2kg of linear low-density polyethylene into the feeding barrel evenly. Set the temperature of the heating cylinder of the extruder to 75°C, 160°C, 180°C, 180°C, 185°C, 85°C, 185°C, 185°C, 190°C along the extrusion direction; the screw speed is 100 r / min. The heating cylinder reaches the predetermined temperature, and 5kg of polyethylene compound is added to the extruder from the main feeding port of the first section of the extruder, and the feeding speed is 0.15kg / min; at the same time, the acetone solution containing maleic anhydride and the initiator is passed through The metering pump injects from the liquid feeding port of the third section of the extruder at a speed of 0.002kg / min, and extrudes to obtain the polyethylene graft bonding resin. After mixing 4kg of polyethylene graft adhesive...

Embodiment 2

[0019] At room temperature, 100 g of maleic anhydride and 8 g of 2,5-dimethyl-2,5-di-tert-butylperoxyhexane were dissolved in 100 g of acetone.

Abstract

The invention discloses an amorphous block copolymer-modified polyvinyl adhesive.A reactive blending process is implemented through twin-screw extrusion for extrusion granulating preparation.The amorphous block copolymer-modified polyvinyl adhesive is prepared from, by weight, 70-95% of polyethylene graft bonding resin, 4-25% of an amorphous block copolymer and 0.5-5% of a compatibilizer.The amorphous block copolymer-modified polyvinyl adhesive has a high vicat softening point temperature and can be applied to various fields such as pipeline corrosion prevention, oil and gas delivery and municipal drainage.

Description

technical field [0001] The invention relates to an amorphous block copolymer modified polyethylene glue, in particular, a polyethylene graft adhesive resin reacted with an amorphous block copolymer resin through a twin-screw extruder. Blending method of preparation. Background technique [0002] At present, polyethylene glue is widely used in pipeline anticorrosion, oil and gas transportation, urban drainage and other fields. Chinese Patent No. CN102533162A introduces a preparation method of PE hot melt adhesive powder for 3PE anticorrosion pipelines. The polyethylene graft adhesive resin, polyolefin matrix resin, elastomer tackifier resin, and leveling agent are extruded and granulated by twin-screw extrusion, and the PE hot melt adhesive is obtained by grinding equipment powder. Chinese Patent No. CN102399519A introduces a hot-melt adhesive for steel-plastic composite pipes and a production method. A polyethylene hot melt adhesive conforming to industry standard CJ / T22...
