A composite biodegradable vapor phase antirust film and its preparation process

Abstract

The invention belongs to the technical field of multi-functional high polymer materials, in particular relates to a composite biodegradation gas-phase anti-rusting membrane and a preparation process thereof, and aims to provide a composite biodegradation gas-phase anti-rusting membrane which is rapid in preparation method, simple to prepare, low in cost and free of environment pollution, and a preparation process thereof. The composite biodegradation gas-phase anti-rusting membrane is prepared from the following raw materials in percentage by mass: 2-5% of a gas-phase anti-rusting additive, 60-75% of a biodegradation material, 5-10% of a polyolefin carrier, 5-10% of a modifier, 2-5% of a plasticizer, 2-3% of a coupling agent, 4-6% of a dispersing agent, 1-3% of a lubricant and 0.1-0.3% of other processing additives. The composite biodegradation gas-phase anti-rusting membrane provided by the invention has the characteristics of good barrier property, conductivity, flame retardancy and ultraviolet ray prevention, and gas-phase anti-rusting gases generated from the composite biodegradation gas-phase anti-rusting membrane can be volatilized and permeated into corners which cannot be covered by anti-rusting oil in package parts, and can be biologically degraded.

Description

technical field [0001] The invention belongs to the technical field of multifunctional polymer materials, and in particular relates to a composite biodegradable vapor phase antirust film and a preparation process thereof. Background technique [0002] At present, the most commonly used anti-corrosion method in industry is to coat the metal surface with anti-rust oil, but the anti-rust oil itself will become invalid due to oxidation. At the same time, it is time-consuming and labor-intensive to remove the metal anti-rust protective layer, which is neither safe. It is not environmentally friendly. The use of desiccant for anti-rust has lower cost, simple operation, and easy removal of protective packaging, but the effective time is short, and it is greatly affected by ambient temperature and humidity. [0003] VCI is a new type of rust prevention. VCI will slowly vaporize at room temperature, and its gas will fill the sealed space. VCI can be adsorbed on the metal surface to ...
