specific Embodiment approach 1

[0013] 1. Production formula (weight ratio, the same below):

[0014] Chlorinated polyethylene (CPE): 55%, low-density polyethylene (LDPE): 40%, carbon black: 2.9%, antioxidant (1010): 0.1%, epoxidized soybean oil: 2%.

[0015] 2. Production process:

[0016] After weighing the raw materials, mix them evenly, send them to the extruder to extrude, then blow the film, and finally carry out the winding inspection.

[0017] The length-to-diameter ratio of the screw of the extruder used in this process is 32, the rotating speed of the roller is 40r / min, the barrel temperature: the feeding section is 170-175°C, the metering section is 160-165°C, and the head temperature is: 170-175°C; the inflation ratio is 2.0 when blowing the film.

specific Embodiment approach 2

[0018] The production process of the specific embodiment 2 is the same as the specific embodiment 1, and the difference is the production formula, which is as follows:

[0019] Chlorinated polyethylene (CPE): 64%, low-density polyethylene (LDPE): 30%, carbon black: 3.9%, antioxidant (1010): 0.1%, epoxidized soybean oil 2%.

[0020] The product produced according to the above process has a thickness of 0.3±0.02 millimeters and a width of 0.2-0.6 meters.

Abstract

A modified polyethylene film comprising the constituents (by weight proportion) of chlorinated polyethylene 55-65%, low density polyethylene 30-40%, carbon black 2-4%, anti-oxidant 0.1%, epoxy soya-bean oil 2%. The preparation process comprises the steps of extrusion and blowing film. The advantages of the present invention are ageing-proof, chemical-resistance, low-temperature resistance, and less temperature distortion.

Description

technical field [0001] The invention relates to a polymer material, in particular to a modified polyethylene film used for crab breeding. Background technique [0002] Crab membrane is an essential material for breeding crabs. The early crab film was an ordinary plastic film, which was eliminated due to its thin thickness, aging resistance and short service life. The currently used crab film is an improved plastic film, which is thicker, but the production process is complicated, and the production cost and raw material cost are high. Contents of the invention [0003] The technical problem to be solved by the invention is that the existing plastic film used for crab breeding has complex production process, high production cost and raw material cost. [0004] The raw materials and proportioning that the modified polyethylene plastic film of the present invention adopts are as follows: [0005] Chlorinated poly...
