Anti-rust polyethylene film material and preparation method thereof, as well as anti-rust bag

Abstract

The invention discloses an anti-rust polyethylene film material and a preparation method thereof, as well as an anti-rust bag. The anti-rust polyethylene film material is prepared from the following raw materials in percentage by weight: 60-70 percent of linear low-density polyethylene, 20-30 percent of high-pressure polyethylene, 2-5 percent of flame-retardant masterbatches and 1-5 percent of anti-rust masterbatches. The preparation method of the anti-static polyethylene film material comprises the following steps: respectively weighing all the components in part by weight; putting all the components in an extruder for extrusion, wherein the temperature of a first zone of the extruder is 145-155 DEG C, the temperature of a second zone is 150-160 DEG C, the temperature of a third zone is 150-160 DEG C, the temperature of a die head of the extruder is 150-170 DEG C, the rotating speed of a lead screw is 100-120 r / min, and the host frequency is 12-14 HZ; after extrusion, cooling, formingand winding to obtain the anti-rust polyethylene film material. As the anti-rust masterbatches are added, the anti-rust polyethylene film material disclosed by the invention has a special anti-rust smell; particles in the anti-rust masterbatches are gasified into gas, and the anti-rust gas can form a protective film on the metal surface to cut off the possibility of contact metal ions with waterand oxygen. Therefore, an anti-rust effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to an antirust polyethylene film material, a preparation method thereof and an antirust bag prepared by using the antirust polyethylene film material. Background technique [0002] Ordinary plastic bags do not have any additional special functions, and many things need simple packaging, but some metal things can be packed in simple packaging, but it will be found in places with high humidity, even if the bag packaging seems to be very good However, some parts of the metal are still rusted. [0003] At present, many mechanical parts in various countries are processed and imported from abroad. We know that normal imports are mainly by sea, and the sea transportation takes a long time, usually around January. The salt in the sea is relatively high, and the humidity is very high. Under normal circumstances, these metal machines are equivalent to staying in an en...
