Abstract

The invention provides a reducing blow molding packing barrel and a preparation method thereof. The reducing blow molding packing barrel is prepared by raw materials in parts by weight as follows: 100 parts of high-density polyethylene, 1.5-2.5 parts of epoxy linseed oil, 0.1-0.3 parts of an ultraviolet light absorber, 0.5-1 part of calcium stearate, 0.5-2 parts of powdered nitrile rubber, 0.06-0.09 part of a main antioxidant and 0.08-0.1 part of an auxiliary antioxidant. The invention further provides a preparation method of the reducing blow molding packing barrel, and a multipoint wall thickness control system for a hollow blow molding parison is introduced. The reducing blow molding packing barrel and the preparation method have the advantages and the benefits as follows: the heat resistance, the toughness effect and the oxidation resistance of a product are improved, production reduction of the product is realized, relatively uniform wall thickness of the final product is guaranteed, and used materials, product weight and environmental pollution are reduced.

Description

Technical field [0001] The invention belongs to the field of blow molding plastics, and in particular relates to a reduced blow molding packaging barrel and a preparation method thereof. Background technique [0002] Packaging is one of the most important application fields of plastic materials, especially for thermoplastic materials. The needs and development of the packaging industry directly change or guide the development direction of plastic material manufacturing and processing technology. Generally speaking, plastic packaging materials and products are currently facing huge pressure in three aspects: first, improving the performance of products, such as increasing the transparency, heat resistance, mechanical strength and barrier properties of materials and products; The second is the pressure from environmental protection; the third is the pressure to reduce costs. The result of the mutual restriction and interaction of the three aspects is that, except for individu...
