经非金属材料改性的热塑性树脂复合材料及制备产品的方法 技术领域
本发明涉及一种热塑性树脂复合材料， 具体地， 涉及一种经硅灰石、 碳 酸钙改性的热塑性树脂复合材料以及利用该材料制备产品的方法， 该复合材 料可用于制作洁具、 洁具五金件、 户外产品、 外墙装饰管材公共景观实用装 饰产品。 背景技术
常见的洁具包括浴缸、 台盆、 座便器、 小便斗， 大部分采用陶土烧制而 成， 先把陶土制成洁具产品进行烧制， 成型后表面上釉再进行烧结， 其烧制 过程需消耗大量煤炭或天然气，造成大量的碳排放和能源消耗，碳排放量大， 尤其是对空气的污染； 而其在烧制过程中由于温度的不对称使产品开裂和变 形导致产品大量的次品和报废， 形成二次污染和成本提高。 同时生产中用的 陶土资源也日益稀少， 一旦资源枯竭， 将无法再用陶土生产洁具产品。
近来， 又有采用人造玛瑙或亚克力来制备卫浴洁具的， 见专利号为
ZL200410040962.6的中国发明专利《采用浇注工艺生成的亚克力座便器》（授 权公告号： CN126923C), 该专利中座便器零部件均采用树脂和玛瑙粉混合 物实心浇注在夹层空壳中的方式来制备座便器， 所得产品虽然具有陶瓷制品 的一般特性， 但该方法相对工艺复杂， 产品观感差， 实用性不好， 并大量消 耗石油副产品， 自洁性不佳。 在此基础， 又公开了另一种亚克力和玻璃钢复 合结构的座便器，见专利号为 ZL200620034821.8的中国实用新型专利《亚克 力和玻璃钢复合结构座便器》 （授权公告号： CN2926350Y), 但其外观似塑 料制品， 感观、 耐用性和使用性都较差。
中国发明专利申请号为 96106392.0的中国发明专利， 申请公开了《人造 大理石制品及其制备方法》 （公开号: CN1167741A)，该申请以大理石粉、 不饱 和聚酯树脂、 氢氧化铝及硅灰石为主要原料通过浇注工艺完成， 产品性能和 制备过程虽然有所提高，但产品笨重、工艺实用性差、平整度和光洁度较差， 发明的公开
'本发明提供了一种经非金属材料改性的热塑性树脂复合材料， 采用该材 料制备的洁具、 洁具五金件、 户外产品、 外墙装饰管材、 公共景观实用装饰 等产品具有低碳、 低能耗、 无污染且具有高韧性、 高强度、 平整和光洁的优 点。
为达到上述目的， 本发明提供了一种经非金属材料改性的热塑性树脂复 合材料， 该材料包含以下按重量百分数计的原料：
填料 50%〜70%; .
聚丙烯 25%〜40%；
马来酸酐改性聚丙烯 3% ~ 6%；
钛白粉 1% ~ 3%;
抗氧剂 1%〜2%；
所述填料采用硬脂酸改性处理过。
所述的填料选择硅灰石或者是碳酸钙或者是硅灰石和碳酸钙的混合物。 所述的改性处理是指， 将重量百分数为 1〜5%的硬脂酸（C16H3202， 熔点 69.6°C )和 95〜99%的填料，采用高速混合机在 90°C〜100°C，混合搅拌 15~30 分钟， 使硬脂酸熔化并与碳酸钙或硅灰石填料充分接触、 碰撞， 达到表面沾 粒的物质改性处理的目的， 改性后的碳酸钙和硅灰石与聚丙烯能充分结合， 大大提高了材料之间的相容性， 同时降低了碳酸钙、 硅灰石表面的吸油性， 大幅度提高了碳酸钙、 硅灰石的添加比例， 使改性的非金属热塑性复合材料 具有高填充的优点。 改性后的非金属材料具有很好的相容性和高填充性， 用 上述改性的非金属复合材料注塑的卫浴产品具有坚硬、 强度高、 耐腐蚀的特 性并具有天然石材的质感。
所述的硅灰石是一种无机针状矿物， 其特点是无毒、 耐化学腐蚀、 热稳 定性及尺寸稳定良好， 有玻璃和珍珠光泽， 低吸水率和吸油值， 力学性能及 电性能优良以及具有一定补强作用； 所述的碳酸钙可以在未经改性处理的状 态下与聚丙烯进行充分的熔融且价格低廉而成为除硅灰石以外的又一较为理 想的填料。 本发明采用不同规格的硅灰石、 碳酸钙或者二者的混合物作为填 料， 可以既保证复合材料的致密性， 又能节约粘合剂。
所述的聚丙烯作为热塑性复合材料的粘合剂。 聚丙烯的特点是结晶度很 高， 相对密度小 （约为 0.90〜0.9.1g/cm2)， 熔点在 170〜175°C范围内， 分子 量一般在 15〜70万之间。聚丙烯表现为宏观世界的耐热性较好，热变形温度 为 90〜105°C。 聚丙烯为非极性高聚物， 有优良的电绝缘性能， 更兼有优良 的耐热性。 此外， '它还有良好的化学稳定性， 聚丙烯几乎不吸水， 除对强氧 化性的酸（发烟硫酸、 发烟硝酸）夕卜， 几乎都很稳定， 耐碱性也很突出。 且 聚丙烯的强度和刚性均超过聚乙烯， 尤其具有突出的耐弯曲疲劳性能； 缺点 是蠕变比聚酰胺和聚氯乙烯要大得多。
进一步地，所述的聚丙烯选择 M700.聚丙烯或 M2600聚丙烯或 M700聚 丙烯与 M2600聚丙烯的混合物；在生产实际中，可以根据要生产的产品的要 求选择合适型号的聚丙烯或者不同型号的聚丙烯的混合物作为粘合剂， 以满 足产品实际需要的硬度和吸附性。
通常， 热塑性树脂的优点是加工成型简便， 具有较高的机械能； 缺点是 耐热性和刚性较差。 本发明采用硅灰石、 碳酸钙或者二者的混合物增强热塑 性树脂而制得的热塑性树脂复合材料， 不仅可使力学性能、 热变形温度、 尺 寸稳定性、 低温冲击性能和老化性能得到不同程度的改善， 还可使某些性能 达到或超过热固性玻璃纤维增强复合材料的水平， 而且仍可以用一般注射方 法成型。
本发明中填料的含量通常在 50%〜70%。 总的来说， 用硅灰石、 碳酸钙 或者二者的混合物改性的热塑性树脂复合材料， 可以达到下述效果： ①提高 拉伸、 弯曲、 压縮等力学强度及弹性模量， 改善蠕变性能； ②提高热变形温 度； ③降低线膨胀系数； ④降低吸水率， 增加尺寸稳定性； ⑤改善热导率； ⑥提高硬度； ⑦抑制应力开裂； ⑧阻迟燃烧性； ⑨改善电性能。
所述的马来酸酐改性聚丙烯是由聚丙烯经反应挤出接枝马来酸酐制得， 由于非极性的分子主链上引入了强极性的侧基， 马来酸酐接枝聚丙烯可以成 为增进极性材料与非极性材料粘接性和相容性的桥梁。 在生产填充聚丙烯时 添加马来酸酐改性聚丙烯， 可极大地改善填料与聚丙烯的亲和性及填料的分 散性。 故能有效地增强填料在聚丙烯中的分散， 从而提高填充聚丙烯的拉伸 和冲击强度。 所述的钛白粉是起到增白的作用。
由于聚丙烯大分子链中的叔碳原子对氧的侵蚀非常敏感， 在光、 热和空 气中的氧作用下容易老化， 故本发明的复合材料还加入抗氧剂以抑制老化过 程。
本发明还提供了利用经非金属材料改性的热塑性树脂复合材料制备洁 具、 洁具五金件、 户外产品、 外墙装饰管材、 公共景观实用装饰等产品的方 法， 该方法包含以下具体步骤：

进一步地， 所述的步骤 6中， 注塑机采用活塞式机筒通过高压将熔融的 复合材料注入到产品的金属模具中。
