Production process of anti-static plastic net

Abstract

The invention discloses a production process of an anti-static plastic net. The process comprises the following steps of mixing polyvinyl chloride, plant cellulose fiber, a modified plasticizer, an antioxidant and a dispersing agent to obtain a blended material, putting the blended material into an extruder to be heated and melted, performing screw extrusion to enter a rotating machine head, enabling the molten blended material to flow through a mold hole to form two strands of molten material filaments, rotating the machine head, and discontinuously converging the two strands of material filaments at one point to form the net. A prepared macromolecular cross-linked structure can improve the intermolecular conductivity, effectively evacuate electrons and achieve the antistatic purpose; and ricinoleic acid with branched chains can generate linear polymerization with relatively high polymerization degree in the polyesterification reaction process, and polyester long chains and chain segments generated during plasticization are stable, so that the flexibility and toughness of the prepared plastic net are enhanced, and the purpose of enhancing the mechanical property of the plastic net is achieved.

Description

technical field [0001] The invention relates to the field of plastic nets, in particular to a production process of antistatic plastic nets. Background technique [0002] Plastic mesh has been widely used in the packaging of various toys, food, vegetables, wine bottles, and mechanical parts. It is also an indispensable material for aquaculture, construction engineering, and road traffic construction. It can also be used to produce car backrests, Simmons mattresses, Air-conditioning mesh, flame-retardant mesh, roadbed mesh, etc.; [0003] However, the existing plastic mesh parts generate static electricity due to friction, contact or induction during use. Static electricity makes the parts themselves easy to absorb dust and absorb dirt, seriously affecting the use of the product, and causing electric shocks to people during processing and use. Even serious accidents such as explosions caused by sparks generated by electrostatic discharge, and the strength of the plastic mesh...
