【技术领域】【Technical field】
本发明属于高分子材料技术领域，具体涉及一种芳香族聚酯/人造石废渣复合材料及其制备方法。The invention belongs to the technical field of polymer materials, in particular to an aromatic polyester/artificial stone waste residue composite material and a preparation method thereof.
【背景技术】【Background technique】
聚对苯二甲酸乙二醇酯(PET)、聚对苯二甲酸丙二醇酯(PTT)和聚对苯二甲酸丁二醇酯(PBT)是最主要的三种半结晶性芳香族聚酯，具有良好的耐磨性、耐热性和耐化学药品性，广泛应用于合成纤维、薄膜和工程塑料等领域。然而，其对石油资源的过度依赖以及本身固有的尺寸稳定性(成型时的尺寸收缩)和难以生物降解等不足不利于芳香族聚酯的可持续发展。Polyethylene terephthalate (PET), polytrimethylene terephthalate (PTT) and polybutylene terephthalate (PBT) are the three most important semi-crystalline aromatic polyesters. It has good wear resistance, heat resistance and chemical resistance, and is widely used in synthetic fibers, films and engineering plastics. However, its excessive dependence on petroleum resources and its inherent dimensional stability (dimension shrinkage during molding) and difficult biodegradation are not conducive to the sustainable development of aromatic polyesters.
人造岗石是由93wt％左右的不同细度的重钙粉末或砂子、7wt％左右的不饱和树脂和少量颜料等，经真空搅拌、高压震荡、固化定型、切割打磨等工序制备而成。具有色泽艳丽、颜色可控可调、环保、可多次翻新等特点，是一种国际流行的绿色环保装饰材料。但在人造岗石生产过程中，由于需要对固化后的人造石进行切割和水淋降温，产生大量包含碳酸钙废渣的废石浆，经沉淀絮凝后的浓缩液中固体废弃物含量约20％，该部分称为人造石废渣。由于废渣表面含有不饱和热固性聚酯残余物，难以二次加工，在自然环境中不能降解，造成严重的环境污染，成为隐藏在光鲜亮丽的人造石背后的最大行业隐患，制约人造石行业的绿色可持续发展。据行业介绍，每条人造石生产线平均每天产生碳酸钙废渣约25吨，不仅造成严重环境污染和水污染，也是资源的极大浪费。Artificial granite is prepared from heavy calcium powder or sand with different fineness of about 93wt%, unsaturated resin and a small amount of pigments about 7wt%, etc., through vacuum stirring, high pressure vibration, curing and shaping, cutting and grinding. It has the characteristics of bright color, controllable and adjustable color, environmental protection, and can be refurbished many times. It is an internationally popular green environmental protection decorative material. However, in the production process of artificial granite, because the solidified artificial stone needs to be cut and cooled by water, a large amount of waste rock slurry containing calcium carbonate waste residue is generated, and the solid waste content in the concentrated solution after precipitation and flocculation is about 20%. , this part is called artificial stone waste. Because the surface of the waste residue contains unsaturated thermosetting polyester residues, it is difficult for secondary processing and cannot be degraded in the natural environment, causing serious environmental pollution and becoming the biggest hidden danger behind the bright artificial stone. sustainable development. According to the industry, each artificial stone production line produces an average of about 25 tons of calcium carbonate waste every day, which not only causes serious environmental pollution and water pollution, but also a great waste of resources.
如何实现人造石废渣的变废为宝和缓解石化资源的过度消耗成为业界最关注的问题。到目前为止，关于芳香族聚酯/人造石废渣复合材料的制备至今尚无报道。How to realize the transformation of artificial stone waste into treasure and alleviate the excessive consumption of petrochemical resources has become the most concerned issue in the industry.

Granulate to prepare material splines. The mechanical properties, heat resistance and molding shrinkage of the tested samples are shown in Table 1.
表1Table 1
通过表1我们发现，人造石废渣的加入在保持芳香族聚酯较高强度的同时，较大幅度提高了芳香族聚酯的热稳定性和显著降低了他们的成型收缩率。因而芳香族聚酯/人造石废渣复合材料具有优异的综合性能。From Table 1, we found that the addition of artificial stone waste residues greatly improved the thermal stability of aromatic polyesters and significantly reduced their molding shrinkage while maintaining the higher strength of aromatic polyesters. Therefore, the aromatic polyester/artificial stone waste slag composite material has excellent comprehensive properties.
