Embodiment 1
[0027] Raw material composition (by weight percentage):
[0037] Pour the raw materials of the above formula into the high-speed mixer one after another, control the stirring speed at 450-480rpm, stir for 3-5 minutes, do operations such as shoveling the edges, shoveling the bottom and discharging water vapor, and then control the stirring speed at 900-960rpm, and then Stir for 10 minutes, knead the uniformly stirred mixture in a twin-screw extruder, and finally extrude, granulate, and screen to obtain a modified masterbatch for multifunctional agricultural greenhouses. The screening method is: use four-layer filter screen, and the filter screen requirement is 80+150+150+...

Abstract
The invention provides a compound gas phase antirust masterbatch which is prepared from a gas phase antirust additive, a polyolefin carrier, a friction additive, an auxiliary function additive, a coupling agent, a dispersing agent, an auxiliary dispersing additive and other processing additives through mixing, stirring, milling and sieving. A gas phase antirust plastic film prepared from the compound gas phase antirust masterbatch of the invention is characterized by high barrier performance, electric conductivity, flame resistance and UV ray screening property. Gas phase antirust gas generated from the film can volatilize and penetrate into corners and spaces of packages where antirust oil can not reach and the gas also has long time antirust effect, thus overcoming the defects of rust prevention with antirust oil or a drying agent and being a quite good antirust material.
Description
technical field [0001] The invention relates to a multifunctional polymer material, in particular to a composite gas phase antirust master batch and a preparation process thereof. Background technique [0002] At present, the most commonly used anti-corrosion method in the 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 Safe and not environmentally friendly. However, 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. As for the packaging and processing of metal materials with special dehumidification equipment, although the anti-rust effect is good, the cost is high, time-consuming and labor-intensive, and the operation is complicated. In a...
