The invention discloses a wear-resistant antiskid polyurethane solid tire and a preparation method thereof. The polyurethane solid tire is prepared from a metal rim and a polyurethane layer, by addingisophorone diisocyanate into polyurethane, the structure of a reaction monomer is changed, and the content of a soft segment in a polyurethane molecular chain is increased, so that a solid tire is not easy to harden at low temperature, good flexibility is kept, the antiskid effect is improved, and the wear resistance is improved; according to the preparation method, a shot blasting device is usedfor carrying out surface treatment on the metal rim, high-speed shot blasting sand is blasted by the shot blasting device to impact the surface of the metal rim, the surface roughness of the metal rim is increased, polyurethane is poured after shot blasting is finished and an adhesive is coated, and the compactness between a polyurethane layer and the metal rim is improved; the shot blasting device separates shot blasting sand according to different particle sizes, damage to the device caused by large-size particles is avoided, and the situation that the quality of the solid tire is reduced due to large particle size difference is avoided.

    本发明公开了一种耐磨防滑的聚氨酯实心车胎及其制备方法,该聚氨酯实心车胎由金属轮辋和聚氨酯层制备得到,通过在聚氨酯中加入异佛尔酮二异氰酸酯,改变了反应单体自身结构,增加了聚氨酯分子链中的软段含量,使得实心车胎在低温下不易硬化,保持了良好的柔软性,提高了防滑效果,且提高了耐磨性能;该制备方法通过使用抛丸装置对金属轮辋进行表面处理,抛丸装置抛射出高速的抛丸砂冲击金属轮辋表面,增加了金属轮辋表面粗糙度,抛丸结束,涂覆胶粘剂后再浇注聚氨酯,提高了聚氨酯层与金属轮辋之间的紧密度;抛丸装置将抛丸砂按照粒径不同分离开,避免大体积的颗粒对装置造成损伤,避免了粒径相差大降低该实心车胎的品质。
