technical field [0001] 本发明涉及高分子材料领域,具体涉及一种发热电缆用聚对苯二甲酸乙二醇酯膜塑料。 Background technique [0002] 聚对苯二甲酸乙二醇酯为乳白色或浅黄色、高度结晶的聚合物,表面平滑有光泽。 It has excellent physical and mechanical properties in a wide temperature range. The long-term use temperature can reach 120 ° C. It has excellent electrical insulation. Even at high temperature and high frequency, its electrical properties are still good, but its corona resistance is poor. Creep resistance, fatigue resistance, friction resistance and dimensional stability are all very good. 由于聚对苯二甲酸乙二醇酯具有结晶性,耐温高的特点,因此其生产的模塑料具有很好的耐温特性和理想的强度,但是由于结晶性高,产品收缩性大,导致产品变形系其欠缺, [0003] 随着科技水平的不断提高,现有的发热电缆用聚对苯二甲酸乙二醇酯塑料的质量、阻燃性、耐高温性、机械强度、硬度等方面已渐渐无法满足产品的使用需求,同时产品的生产成本严重制约着聚对苯二甲酸乙二醇酯的发展。 Contents of the invention [0004] 针对现有技术的不足,本发明提供了一种发热电缆用聚对苯二甲酸乙二醇酯膜塑料,具有优异的阻燃性、耐高温性、机械强度以及硬度。 [0005] To achieve the above object, the present invention is achieved through the following technical solutions: [0006] 本发明提供了一种发热电缆用聚对苯二甲酸乙二醇酯膜塑料,由以下重量份数的原料制备而成:聚对苯二甲酸乙二醇酯:...

AI Technical Summary

Problems solved by technology

Since polyethylene terephthalate has the characteristics of crystallinity and high temperature resistance, the molding compound produced by it has good temperature resistance and ideal strength, but due to high crystallinity, the product shrinkage is large, resulting in Product deformation is its lack,

[0003] With the continuous improvement of the level of science and technology, the quality, flame retardancy, high temperature resistance, mechanical strength, hardness and other aspects of the existing polyethylene terephthalate plastics for heating cables have gradually been unable to meet the needs of the product. At the same time, the production cost of the product seriously restricts the development of polyethylene terephthalate.
