Abstract

The invention discloses a polyethylene / nylon composite material. The polyethylene / nylon composite material comprises, by weight, 10-20 parts of polyethylene, 30-60 parts of nylon 6, 2-8 parts of nano silicon dioxide, 1-5 parts of dibutyl maleate, 2-6 parts of zinc maleate, 5-8 parts of glass fibers, 1-3 parts of silane coupling agent, 6-10 parts of white oil, 1-5 parts of octadecyl trimethyl ammonium chloride, 0.1-0.3 part of dicumyl peroxide, 0.8-2.5 parts of antioxygen and 1-3 parts of other auxiliaries. The invention further discloses a preparing method of the polyethylene / nylon composite material. The polyethylene / nylon composite material is good in heat resistance and high temperature resistance, excellent in low temperature impact resistance, good in waterproof performance, and high in dimensional stability; in addition, the raw materials are nontoxic, and environmental protection is facilitated.

Description

Technical field: [0001] The invention relates to the field of polymer modification, in particular to a polyethylene / nylon composite material. Background technique: [0002] Nylon, the scientific name of polyamide, is the first of the five general-purpose engineering plastics. Since the invention by W.H.Carothers of DuPont in the 1930s, the production capacity and output of nylon have ranked first in engineering plastics. Nylon has high mechanical strength, high melting point, wear resistance, oil resistance and general solvent resistance, and resistance to plastics. Excellent thermal properties. However, due to the formation of hydrogen bonds between the amide groups of nylon and water molecules, compared with hydrophobic polymers such as polyolefins, it has greater water absorption, resulting in poor dimensional stability of the product, low impact strength in dry state or low temperature, Opaque, poor solubility and other shortcomings. With the continuous advancement of...
