Abstract

The invention discloses a high-strength and corrosion-resistant plastic sheet pile and a preparation method thereof. The high-strength and corrosion-resistant plastic sheet pile is prepared from the following raw materials: polyvinyl chloride, a plasticizing agent, filler, a heat stabilizer, an ultraviolet absorbent, vinyl pyridine, vinyl pyrimidine, an initiator, zirconia fiber, rosin pyrolytic polymer and wholly aromatic copolyester. The plastic sheet pile is prepared by the steps of mixing, extruding and mold pressing and the like. The high-strength and corrosion-resistant plastic sheet pile and the preparation method disclosed by the invention have the beneficial effects that by adoption of the zirconia fiber, the rosin pyrolytic polymer and the wholly aromatic copolyester as a reinforcement system, so that the corrosion resistance and the hardness of the plastic sheet pile are improved.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a high-strength corrosion-resistant plastic sheet pile and a preparation method thereof. Background technique [0002] Polymer plastic sheet pile is a fast, efficient and environmentally friendly form of pile foundation. Light material, high strength, good water-stop performance; anti-corrosion, strong weather resistance, long service life; reusable and recyclable; in line with the national advocacy of "plastic strip steel" and "replacing wood with plastic" Energy-saving and environmental protection policies; products adopt industrialized large-scale production and mechanized construction, with high efficiency, short construction period (one-thirtieth of traditional stone embankment construction), and low construction cost (two-thirds of traditional stone embankment construction, steel plate one-half of the pile construction). [0003] Polymer plastic sheet piles ma...
