Embodiment 1

[0025] A HDPE composite material for skis, its components and parts by weight are: 55 parts of HDPE, 14 parts of silicon carbide fiber, 8 parts of CPE, 9.5 parts of superfine magnesium hydroxide, 0.8 parts of antioxidant 1076, and 0.9 parts of UV-531 1 part, 1 part of antistatic agent 1800, 1.5 parts of nano zinc oxide, 4 parts of ABS, 0.7 part of PE wax, 0.2 part of zinc stearate, 0.2 part of coupling agent.

[0026] The steps of its preparation method are as follows:

[0027] (1) Dissolve the rare earth in water and disperse evenly to prepare a rare earth solution with a mass fraction of 1%, immerse the silicon carbide fiber in the rare earth solution, move it to a constant temperature water bath at 80°C and stir for 1 hour, take it out and place it in a vacuum drying oven Dry at 100°C for 5 hours, and cut into short fibers with a length of 10 μm after cooling for later use;

[0028] (2) Put the short fiber and HDPE powder obtained in step (1) into a mortar and grind for 1 ...

Embodiment 2

[0030] A HDPE composite material for skis, its components and parts by weight are: 50 parts of HDPE, 12 parts of silicon carbide fiber, 9.5 parts of CPE, 9 parts of superfine magnesium hydroxide, 0.7 part of antioxidant 1076, 0.5 part of UV-531 1.2 parts of antistatic agent 1800, 1.4 parts of nano zinc oxide, 7 parts of ABS, 0.9 parts of PE wax, 0.5 parts of zinc stearate, and 0.2 parts of coupling agent.

[0031] Its preparation method is the same as Example 1.

Embodiment 3

Abstract

The invention provides an HDPE composite material for a snowboard. The HDPE composite material for the snowboard comprises, by weight, 50-65 parts of HDPE, 10-15 parts of silicon carbide fibers, 8-12 parts of CPE, 8-10 parts of fire retardant, 0.5-1 part of antioxygen, 0.5-1 part of ultraviolet light absorber, 0.9-1.4 parts of antistatic agent, 1-2 parts of light screener, 3-8 parts of flexibilizer, 0.7-1.2 parts of dispersing agent, 0.1-0.6 part of stabilizer and 0.1-0.3 part of coupling agent. The invention further provides a preparation method of the HDPE composite material. The HDPE composite material for the snowboard has good creep resistance and environmental cracking resistance.

Description

Technical field: [0001] The invention relates to a composite material, in particular to an HDPE composite material for skis and a preparation method thereof. Background technique: [0002] HDPE is the English name of high-density polyethylene - the abbreviation of HighDensityPolyethylene, which is a high crystallinity, non-polar thermoplastic resin. The appearance of the original HDPE is milky white, and the thin section is translucent to a certain extent. HDPE is a non-toxic, tasteless, odorless white granule with a melting point of about 130°C, a relative density of 0.941-0.960, a crystallinity of 80%-90%, a softening point of 125-135°C, and a service temperature of up to 100°C. It has good heat resistance and cold resistance, good chemical stability, high rigidity and toughness, good mechanical strength, good wear resistance, and good electrical insulation wire. HDPE's good wear resistance, rigidity, toughness, and cold resistance make it suitable for sports products. ...
