Integrally-formed composite sleeper, preparation process and preparation device
The invention provides an integrally-formed synthetic sleeper, a preparation process and a preparation device.The integrally-formed synthetic sleeper comprises a polyurethane resin matrix, continuous glass fibers are longitudinally arranged in the polyurethane resin matrix and used for longitudinal reinforcement of the synthetic sleeper, and a reinforcement layer composed of glass fiber fabric and polyurethane resin is arranged on the surface of the polyurethane resin matrix. The thickness of the reinforcing layer is 1 to 10 mm; the overall density of the synthetic sleeper is 0.64-1.4 g/cm < 3 >, and the polyurethane resin accounts for 35-50% of the total weight of the synthetic sleeper; the continuous glass fiber accounts for 35-60% of the total weight of the synthetic sleeper, and the glass fiber fabric accounts for 3-10% of the total weight of the synthetic sleeper; the overall strength of the composite sleeper can be remarkably improved, and transverse cracking is avoided.
本发明提供一种一体成型合成轨枕、制备工艺及制备装置，包括聚氨酯树脂基体，连续玻璃纤维在聚氨酯树脂基体内纵向设置，用于合成轨枕的纵向增强，聚氨酯树脂基体的表面设置有玻璃纤维织物和聚氨酯树脂组成的增强层，所述增强层的厚度为1～10mm；合成轨枕的整体密度为0.64～1.4g/cm3，其中聚氨酯树脂占合成轨枕总重量的35～50％；连续玻璃纤维占合成轨枕总重量的35～60％，玻璃纤维织物占合成轨枕总重量的3～10％；本申请能够显著增加合成轨枕的整体强度，避免横向开裂。
