Description

高强度PVC、TPU共混改性配方
技术领域
本发明涉及一种高分子复合材料配方，特别是一种PVC管材配方。
背景技术
PVC管材具有较高的硬度、耐腐蚀性，但强度还需进一步改善。
发明内容
本发明针对现有技术的不足，提出一种能显著提高强度的高强度PVC、TPU共混改性配方。
本发明通过下述技术方案实现技术目标。
高强度PVC、TPU共混改性配方，其改进之处在于：每100份PVC树脂配备：52～55份TPU树脂、3.6～3.9份三碱式硫酸铅、2～3份二碱式亚磷酸铅、1.6～1.9份CaSt、0.9～1.1份BaSt、0.3～0.6份HSt、0.5～0.8份石蜡共混而成。
进一步改进在于：每100份PVC树脂配备：53～54份TPU树脂、3.7～3.8份三碱式硫酸铅、2～2.5份二碱式亚磷酸铅、1.7～1.8份CaSt、1.0～1.05份BaSt、0.4～0.5份HSt、0.6～0.7份石蜡共混而成。
本发明与现有技术相比，具有以下积极效果：
1、加入TPU树脂，可显著提高强度。
2、每100份PVC树脂配备：53～54份TPU树脂、3.7～3.8份三碱式硫酸铅、2～2.5份二碱式亚磷酸铅、1.7～1.8份CaSt、1.0～1.05份BaSt、0.4～0.5份HSt、0.6～0.7份石蜡共混而成，可进一步提高强度。
