Abstract

The invention discloses a PE160 grade composite material for pipes. The PE160 grade composite material comprises the following ingredients in parts by weight: 100 parts of HDPE (high-density polyethylene) resin, 0.5 to 50 parts of inorganic rigid particles, 1 to 40 parts of ultrafine fibers and 0.05 to 10 parts of functional raw materials. The invention also discloses a preparation method of the material. The preparation method comprises the following steps that A, raw materials except the ultrafine fibers in the recipe are selected and are placed into a high mixing machine; B, the materials which are uniformly mixed in the step A are added into a material tube of a plastic extruding machine, the temperature is set, the screw rod rotating speed and the feeding speed are regulated, and the ultrafine fibers are fed in the second section of the plasticization; and C, normal wire drawing cooling, particle cutting, baking and package are carried out. The PE160 grade composite material has the beneficial effects that the goals of enhancing the intensity and the rigidity of polyethylene, reducing the linear expansion factor, improving the mechanical property and thermal performance can be realized, the work pressure is improved, the safety and the reliability are higher, the ring rigidity, the intensity and the toughness are more excellent, in addition, the weight is light, the impact resistance is high, and the damage cannot occur.

Description

technical field [0001] The invention relates to the technical field of polymer composite materials, in particular to a composite material for PE160 grade pipes and a preparation method thereof. Background technique [0002] High-density polyethylene (High Density Polyethylene, referred to as "HDPE") is a non-polar thermoplastic resin with high crystallinity, soft and tough, but slightly harder than LDPE, and slightly elongated, non-toxic, tasteless. PE has excellent resistance to most domestic and industrial chemicals, is non-hygroscopic and has good water vapor resistance. HDPE also has good electrical properties, especially the high dielectric strength of the insulation. However, HDPE has poor mechanical properties, easy deformation, aging, brittleness, and stress cracking, which restricts the wide application of HDPE. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art, and provide a composite mater...
