人造大理石填充剂空心玻璃微珠

产品介绍    空心玻璃微珠是高强度轻质添加剂，用于许多种类的复合泡沫配方中，以降低密度、保温和增强浮力。    空心玻璃微珠（中空玻璃微珠）是一种微小，中空的圆球状粉末。粒径可根据需要在 1-200微米之间任意选择，密度在 0.1-0.7g/㎝ 3。具有重量轻体积大、导热系数低、抗压强度高，分散性、流动性、稳 定性好的优点。另外，还具有绝缘、自润滑、隔音、不吸水、耐火、耐腐蚀、防辐射、无毒等优异性能。 本产品可直接填充于绝大部分类型的热固性、热塑性树脂产品中，起到减轻产品重量，降低成本，消除产 品内应力确保尺寸稳定性，提高抗压、抗冲击性，耐火度、隔音隔热性、绝缘性等等作用！并且还可取替 部分青铜粉、二硫化钼和白炭黑等一些昂贵的填充材料。 空心玻璃微珠，是由无机材料构成的。按化学成份有：二氧化硅、氧化铝、氧化锆、氧化镁、硅酸钠等。 其粒径十到几百微米，壁厚几个微米，为内部充斥 CO2 等气体的封闭微型球体。并且具有质轻、低导热、 无毒、不燃，化学稳定性好、高分散等优点。是人造大理石、带木产品、玻璃钢、原子灰、油漆、塑料、化工、 建材等行业极好的产品填充剂。 产品特点： 1、中空、薄壁、坚硬、轻质的球体。具有最高强度/密度比，适合多种工艺条件。2、更高的填充量。由于和其它形状的填料相比，具有最小的表面积体积比，且吸油量低，可降低树脂的用量，增加填料的用量，而且体积较小的微球填充了体积较大的微球间的空隙，就增加了固含量，降低了VOC，同时也降低了成本。3、降低粘度，增加流动性。不像其它不规则形状的填料，能像轴承里的钢珠一样滚动，因此降低了产品的粘度和内在的应力，从而带来各种好处：注塑时更容易挤出；最终产品不容易翘曲和收缩；减少树脂的用量等等。4、体积成本更经济。5020与相同重量的普通填料相比较，能占据更多的体积。这意味着当考量单位体积成本时，而非单位重量成本时，5020能降低成本，5、有效降低密度。添加5%就能使密度由1.3降到1.0以下。6、熔点高，大大提高耐温性，起到很好的防火作用。 7、微粒球形的结构使其对冲击力和应力有很好的分散作用，能很好地提高涂膜的抗外力冲击性能，而且也能减少因热胀冷缩产生的应力开裂。 8、具有更佳的防水，防污，防腐蚀性能。化学惰性的表面抗化学腐蚀，当成膜时的微粒排列紧密，形成低孔隙率，使涂层表面形成对潮气及致腐蚀离子有阻挡作用的保护膜，起到很好的防护作用。 空心玻璃微珠的应用举例： 1、中空玻璃微珠较大的用途是人造大理石。在发达国家制造商正在使用这种填料,这种材料具体有以下优点: ①改善冲击性能,正确配方制造的产品其性能高于人造大理石协会的要求。 ②改善纹理布局及颜色的连续性,使得产品更加美观、耀目。③降低固化时间,具有较快的模具周转速度。④改善冲击强度,提高抗龟裂能力,降低产品的破损率。⑤改善机械加工性,减少去飞边、切割、钻空和打磨的时间。⑥降低后处理工具的磨损。⑦改善浅颜色的着色性能,同时降低ＴｉＯ2 的用量(虽然有时需要混入一些较深的颜色)⑧重量轻,使其在搬运及安装过程中变得更容易,也降低了运输成本。 以上所列的优点③～⑧能够明显降低成本。   表 1 为人造大理石标准配方及含中空玻璃微珠配方所用树脂粘度为 600～2000ｃＰ,采用中空玻璃微珠不会 造成混合体系粘度的增加。在这个配方中重量占 3.8%的中空玻璃微珠其体积可达 26.8%,这样会使其最终 重量降低 30%。由于树脂的粘度、当时的环境温度及碳酸钙的粒度是影响混合物体系粘度的主要原因,因 此应优化这些因素,使其纹理更流畅、气泡更易排除,特别是当树脂的温度小于 21℃时。碳酸钙的粒度应小于 30 目,以减少对玻璃微珠的损伤. 表 1  配方中是不含有中空玻璃微珠的人造大理石密度比较<table border= "0 "><tr><td style= "border: #000000 0.5pt solid;
