Moulding and processing technology of polyethylene foaming cotton (EPE pearl cotton)

Abstract

Disclosed is a moulding and processing technology of polyethylene foaming cotton (EPE pearl cotton). The moulding and processing technology includes the following processes of material preparing, specifically, a material is sliced, punched, cut and machined into blank materials of the appropriate size; mold opening, specifically, mold cavities and molds which are in the same shape with a target product are manufactured, and the specific shape needs to be taken into account in the process of mold opening in order to arrange and manufacture air exhausting holes or a vacuumizing device; mouldingand shaping, specifically, the blank materials are heated and then pressed for moulding by using the molds, cooling and shaping are conducted, and air exhausting or vacuumizing is needed in the process of pressing to make the blank materials be matched with the molds to manufacture semi-finished products; and finishing, specifically, the formed semi-finished products are taken out of the molds, and trimmed into finished products. According to the moulding and processing technology, the materials can be conveniently processed into products of various special modeling, the labor cost is reduced,the use of glue is avoided, environmental pollution is reduced, the work efficiency is improved, bottleneck that the product promotion degree is not enough is broken through, and the use range is expanded.

Description

technical field [0001] The invention belongs to the technical field of reprocessing of polyethylene foamed cotton, and in particular relates to a molding process of polyethylene foamed cotton (EPE pearl cotton). Background technique [0002] Polyethylene foamed cotton is a non-cross-linked closed-cell structure, also known as EPE pearl cotton, which is a new type of environmentally friendly packaging material; it is composed of low-density polyethylene through physical foaming to produce countless independent bubbles; Fragile, deformed, and poor recovery; it has many advantages such as water and moisture resistance, shock resistance, sound insulation, heat preservation, strong toughness, recycling, environmental protection, and strong impact resistance. It also has good chemical resistance and is a traditional packaging material. However, the current modeling is basically processed by punching, laminating and grinding. The labor cost is relatively high, and glue needs to be ...

[0002] Polyethylene foamed cotton is a non-cross-linked closed-cell structure, also known as EPE pearl cotton, which is a new type of environmentally friendly packaging material; it is composed of low-density polyethylene through physical foaming to produce countless independent bubbles; Fragile, deformed, and poor recovery; it has many advantages such as water and moisture resistance, shock resistance, sound insulation, heat preservation, strong toughness, recycling, environmental protection, and strong impact resistance. It also has good chemical resistance and is a traditional packaging material. However, the current modeling is basically processed by punching, laminating and grinding. The labor cost is relatively high, and glue needs to be used, which increases waste and environmental pollution. The cost is too high, and it is difficult to manufacture. A special shape is a bottleneck in the application and promotion of this material
