Problems solved by technology
[0003] The purpose of the present invention is to provide a polyethylene coating material and coating process to solve the problem that the prior art adopts pvc coating material which is not environmentally friendly and will easily cause damage to human skin after being woven into cloth; polyester fiber and polyethylene There is a phenomenon of polar repulsion in the film, there is no oil on the polyester fiber, the yarn is prone to static electricity due to friction, the extruder uses a single-slot screw, the extrusion effect is not good, the original water cooling temperature is constant, and it is not easy to control the yarn The weavability of the thread makes it impossible to make the polyethylene film and polyester fiber better covered, which affects the quality of the product and the promotion of the market.

Embodiment
[0014] Take the production of red polyethylene film and coating process as an example:
[0015] The distribution ratio of its raw materials is: polyethylene (PE): 66%, toughening agent EVA: 22.5%, anti-ultraviolet agent C81: 3.5%, antistatic agent I129: 4%, environmental protection red masterbatch: 4%.
[0016] Its coating process is as follows:
[0017] 1. Polyethylene mixing: In addition to the environmentally friendly red masterbatch, configure the number of raw materials according to the formula ratio, and then stir in a low-speed mixer at a medium and low temperature of 25°C for 16 minutes to make it fully mixed.
[0018] 2. Polyethylene granulation: Put the mixed raw materials into the extruder for production. The temperature is controlled between 115°C to produce granular products, which are cooled by water and dried.
[0019] 3. Add red masterbatch to polyethylene: Stir the granule product and environmentally friendly red masterbatch with a mixer at low speed for 18 m...

The invention discloses a polyethylene coating material and a polyethylene coating technology, and belongs to the technical field of compounding of materials. The polyethylene coating material comprises the following raw materials: 59 to 73 percent of polyethylene (PE), 20 to 25 percent of toughening agent, 2 to 5 percent of anti-ultraviolet agent, 2 to 5 percent of anti-static agent, and 3 to 6 percent of environment-friendly color master batch. The technology comprises the following steps of: mixing the PE, granulating the PE, adding the color master batch into the PE, coating and rolling. The PE coating material has the advantages of high environment-friendly requirement, halogen prevention, low temperature resistance, high temperature resistance, light specific gravity, high color fastness, abrasion and compression resistance, electrostatic resistance and the like.
Description
technical field [0001] The invention belongs to the technical field of material compounding. Background technique [0002] In the field of sunshade industry, polyvinyl chloride (pvc) is usually used as the material for covering polyester fiber. PVC material covering polyester fiber is not environmentally friendly, and it is easy to cause damage to human skin after being woven into cloth. In the past nearly ten years, relevant technical personnel have tried to directly use environmentally friendly polyethylene materials that are harmless to the human body to make coating materials, and have continuously improved the coating process. However, there are polar phases between polyester fibers and polyethylene films. Repellent phenomenon, no thread oil on the polyester fiber, the yarn is prone to static electricity due to friction, the extruder uses a single-slot screw, the extrusion effect is not good, the original water cooling temperature is constant, it is difficult to control...
