Embodiment Construction

[0011] HDPE 100 kg, LLDPE 35 kg, antioxidant 1076 0.3 kg, methyltriethoxysilane 0.3 kg, polyethylene wax 0.3 kg, silicone acrylate 0.02 kg, zinc stearate 0.3 kg.

[0012] Each component is weighed according to the proportion, mixed uniformly, melted and kneaded, extruded and granulated to obtain the HDPE and LLDPE blended cable plastic.

[0013] The invention uses LLDPE as a modifying agent, which can effectively improve the brittleness of pure HDPE products, improve toughness and strength, and reduce the raw material cost of products.

Abstract

The invention discloses a HDPE-LLDPE-blended cable plastic comprising, by weight, 100 parts of HDPE, 30-40 parts of LLDPE, 0.2-0.4 parts of antioxidant 1076, 0.2-0.4 parts of methyl triethoxysilane, 0.2-0.4 parts of polyethylene wax, 0.01-0.03 parts of silicone acrylate, and 0.2-0.4 parts of zinc stearate. According to the invention, by utilization of LLDPE as a modifying agent, brittleness, toughness and strength of pure HDPE products are effectively improved, and material cost for products is reduced.

Description

technical field [0001] The invention relates to a plastic material, in particular to HDPE and LLDPE blended cable plastic. Background technique [0002] HDPE, High Density Polyethylene (High Density Polyethylene), is a highly crystalline, non-polar thermoplastic resin. The appearance of the original HDPE is milky white, and the thin section is translucent to a certain extent. PE has excellent resistance to most domestic and industrial chemicals. Certain classes of chemicals can cause chemical corrosion, such as corrosive oxidizers (concentrated nitric acid), aromatic hydrocarbons (xylene) and halogenated hydrocarbons (carbon tetrachloride). The polymer is non-hygroscopic and has good water vapor resistance for packaging purposes. HDPE has good electrical properties, especially the high dielectric strength of the insulation, making it very suitable for wires and cables. Medium to high molecular weight grades have excellent impact resistance at room temperature or even dow...
