Problems solved by technology

The process of natural or synthetic polymer resin molecules in the molten state and the uniform distribution of additive molecules around them is called plasticization. This process has been reached and it is called plasticized. If it has not been reached, it is considered not yet plasticized. Existing plastics The bag has the problems of poor tensile properties and poor toughness, which need to be solved urgently

Abstract

The invention discloses a production method of a plastic packaging bag. The production method comprises the following steps: mixing magnesium hydroxide and sodium oxalate and grinding; adding polyethylene glycol acrylate, epichlorohydrin and cyclohexanone and uniformly mixing; adding tetrabutylammonium fluoride and potassium hydroxide, stirring, washing and precipitating; adding water and sodium dodecyl sulfate, stirring, filtering, washing and drying until the weight is constant; dispersing and grinding to obtain a first material; uniformly stirring polycarbonate, etherified starch, octadecytrimethyl ammonium bromide, montmorillonite, zeolite powder and an antioxidant to obtain a second material; calcining kaolin and crushing; adding hydrochloric acid, standing, filtering, washing and drying; adding the second material, the first material and cetyl sodium sulfate, continually stirring, kneading, melting, extruding and granulating; molding and cutting to obtain the plastic packaging bag.

Description

technical field [0001] The invention relates to the technical field of plastic packaging bags, in particular to a production method of the plastic packaging bags. Background technique [0002] Plastic is a synthetic or natural polymer resin as the main material. After adding various additives, it has ductility under a certain temperature and pressure, and can fix its shape after cooling. The process in which natural or synthetic polymer resin molecules are in a molten state and the auxiliary molecules are evenly distributed around it is called plasticization. This process has been reached, and it is called plasticized. The bag has the problems of poor tensile properties and poor toughness, which need to be solved urgently. Contents of the invention [0003] Based on the technical problems existing in the background art, the present invention proposes a method for producing a plastic packaging bag. The obtained plastic packaging bag has good tensile properties, high tough...
