Abstract

The invention discloses a gasified antirust film for silver products and a manufacturing method thereof. The gasified antirust film comprises the following raw materials in parts by weight: 3 to 9 parts of sodium formate, 1 to 3 parts of dextrine, 4 to 8 parts of benzotriazole, 4 to 12 parts of methylbenzotriazole, 2 to 6 parts of sodium molybdate, 1 to 3 parts of zinc oxide and 2500 to 7500 partsof low-density polyethylene; a dispersant comprises the following components in parts by weight: 3 to 7 parts of hydroxyethyl cellulose, 5 to 9 parts of zinc stearate and 5 to 9 parts of polyethylene wax; and a additive comprises the following components in parts by : 80 to 120 parts of oxygen-bearing biodegradable additives and 350 to 650 parts of metallocene paraffin polymer. The manufacturingmethod comprises the steps of preparing raw materials, crashing the raw materials, adding secondary raw materials, adding the additive and blow forming. The manufacturing method is simple, quick andefficient. The invention has advanced process, not only improves the biodegradability of the product, but also strengthens the physical properties, maintains the uniform antirust properties as well asdiscoloration preventing performance and solves the environmental problem caused by the destruction of traditional packaging films.

Description

technical field [0001] The invention relates to packaging materials for silver products, in particular to a gasification antirust film for silver products and a manufacturing method thereof. Background technique [0002] Silver, aluminum, and copper products should be protected from discoloration or corrosion due to oxidation during packaging, transportation, and storage. Therefore, it is often necessary to use a plastic film to coat the surface of the silver product. At present, ordinary packaging films have certain limitations in preventing discoloration of silver products when packaging silver products, copper and aluminum products. The anti-discoloration and anti-rust performance is not good, and additional preservatives are required to maintain its anti-rust function. In addition, the production technology of this anti-corrosion and anti-discoloration packaging film for silver products also has certain defects, and it is impossible to produce a silver product packaging...
