Problems solved by technology

However, multi-layer composite materials usually adopt the method of multi-step extrusion and compounding. The process is complicated, which will cause multiple energy losses, consume a lot of manpower, material and financial resources, and increase production costs.
At the same time, due to the insufficient bonding between the materials of each layer, it is easy to produce obvious gap interfaces between layers, and the inner layer materials are easily polluted and damaged during storage and transportation, and the sheath is damaged from the inner layer. Adverse effects on the overall performance of the product

preparation example Construction

[0021] The present invention also provides a preparation method of modified polyethylene material, which mainly weighs and mixes the above-mentioned raw materials for preparing modified polyethylene according to parts by weight. The modified polyethylene material is obtained after water cooling, dehydration and homogenization.

[0022] The present invention also provides a processing method of the anti-rodent and ant sheath and the anti-rodent and ant sheath prepared therefrom. The modified polyethylene material is used as the inner layer material of the double-layer co-extrusion, and the nylon material is used as the outer layer of the double-layer co-extrusion. Co-extruded layers of materials were prepared.

Embodiment 1

[0024] The present embodiment provides a kind of maleic anhydride grafted polyethylene material, and this maleic anhydride grafted polyethylene material is prepared as follows: Weigh 64kg of linear low density polyethylene, 16kg of high density polyethylene and 0.8kg of horse To acid anhydride, the dicumyl peroxide that takes 0.15kg is dissolved in the mineral oil of 0.8kg, forms dicumyl peroxide slurry. The linear low density polyethylene used in this embodiment is a material with a melt flow rate of 2 g / 10 min, and the high density polyethylene is a material with a melt flow rate of 8 g / 10 min. Mix and stir the linear low density polyethylene, high density polyethylene, maleic anhydride and dicumyl peroxide slurry, send the stirred raw materials into the feeding port of the twin-screw granulator, set the first to tenth zones and the machine The temperature of the head is 180°C, 185°C, 195°C, 215°C, 215°C, 215°C, 220°C, 220°C, 225°C, 225°C, 230°C, and the material temperature...

Embodiment 2

[0026] The difference between the present embodiment and the first embodiment is mainly that the maleic anhydride grafted polyethylene of the present embodiment consists of 72kg of linear low density polyethylene, 18kg of high density polyethylene, 1.4kg of maleic anhydride and diisoperoxide Propylbenzene slurry is made, and dicumyl peroxide slurry is dissolved in the mixed solvent that 0.4kg butyl acetate and 1.1kg white oil are formed by the dicumyl peroxide of 0.23kg, and other technological process is all with embodiment one same.

Abstract

The invention discloses a modified polyethylene material and a preparation method thereof, a rat-proof and ant-proof sheath and a processing method thereof, and belongs to the technical field of polymer modification. The modified polyethylene material disclosed by the invention is prepared from the following raw materials in parts by weight: 25 to 35 parts of an ethylene-vinyl acetate copolymer, 25 to 35 parts of maleic anhydride grafted polyethylene, 25 to 35 parts of linear low-density polyethylene, 10 to 15 parts of high-density polyethylene, 3 to 8 parts of polyethylene wax, 0.1 to 0.2 part of dicumyl peroxide, 5.5 to 7.8 parts of color master batch and 0.3 to 0.6 part of an antioxidant. The invention also provides a preparation method of the modified polyethylene material, the rat-proof and ant-proof sheath prepared from the modified polyethylene material and the processing method thereof. The preparation process and the product have the advantages of no pungent smell, more environmental protection and safety.

Description

technical field [0001] The invention relates to a modified polyethylene material, a preparation method, a rodent-proof sheath and a processing method, and belongs to the technical field of polymer modification. Background technique [0002] With the development of electric power and electronic information industry, the amount of cables and optical cables used as transmission media has increased sharply. The cables and optical cables are covered with sheaths to protect the cables and optical cables. The sheath not only has the effect of insulating and protecting the cables. , can also protect electrical and optical cables from moisture, extreme temperature environments, etc. At present, most of the sheath materials used are plastic products, which are easy to be bitten by rat ants early on, resulting in damage to the sheath layer of the cable or optical cable, especially in subtropical regions where rat ants frequently appear, which is harmful to the sheath and even The dama...
