Preparation method of coating protective plastic capable of being bonded with metal

Abstract

The invention relates to the technical field of coated plastic production, in particular to a preparation method of coated protective plastic capable of being bonded with metal, which comprises the following steps: S1, feeding raw materials; raw materials for manufacturing wrapping plastic are subjected to kneading and cold mixing treatment, kneading of the raw materials is completed through a kneading machine, side-by-side tangent differential arrangement is adopted, namely, the speed of one stirring paddle is high, the speed of the other stirring paddle is low, so that shearing force is generated, the mixed materials can be rapidly sheared due to different paddle speeds, and therefore the materials can be evenly mixed; cold mixing of raw materials is completed through the cold mixing machine, the cold mixing machine is provided with a cooling pipe, a cooling system is used for injecting a cooling agent into the cooling pipe through a water inlet, then the raw materials in a machine body are cooled, an automatic cutting machine is used for cutting a plastic film covered with release paper into a preset shape, and leftover materials are recycled; and the cut wrapping plastic finished products are collected and wrapped in a centralized mode, the metal parts can be directly wrapped after the release paper is torn off, and use is convenient.

Description

technical field [0001] The present application relates to the technical field of coated plastic production, in particular to a method for preparing a coated protective plastic that can be bonded to metal. Background technique [0002] In daily life, it is necessary to produce plastic film to wrap metal parts; [0003] For example, the Chinese invention patent discloses: the preparation method of degradable ultra-thin plastic film, publication number: CN113372635A, its main components can be decomposed naturally, which is conducive to environmental protection; [0004] However, when wrapping and protecting metal parts, plastic parts and metal parts are not easy to stick, and need to use additional fixing parts or apply glue separately for adhesion, which is inconvenient to wrap directly. Therefore, a wrapping that can be bonded to metal is proposed. Preparation method of protective plastic. Contents of the invention [0005] The object of the present invention is to provi...
