Description
技术领域
本发明涉及石材加工技术领域,具体说是一种复合人造石板及其生产方法。
背景技术
目前随着自然资源的日趋匮乏和环保意识的逐渐加强,天然石材的生产受到越来越多的限制,人造石材的应用则越来越广泛。传统的人造石材,普遍采用树脂作为胶结料,容易产生徐变问题,因此厚度通常要比天然石材和陶瓷类材料要厚要重许多,增加了人造石材的资源消耗及成本,限制了人造石材的推广应用。为了降低人造石材的重量和厚度,专利号为CN102322121A的中国发明专利公开了一种由泡沫铝板和人造石板复合而成的复合人造石材,通过将减厚人造石板与轻质高强刚度大的泡沫铝板进行复合,实现了人造石材的轻量化和薄型化生产,降低了人造石材的资源消耗和生产成本。但这种复合人造石材在使用过程中,由于泡沫铝板和人造石板的热胀冷缩系数不一致,导致人造石板容易发生翘曲变形,人造石板与泡沫铝板容易发生剥离,降低了产品的品质和使用寿命。
发明内容
为了克服上述现有技术的缺陷,本发明所要解决的技术问题是提供一种轻薄且不易发生翘曲变形和层间剥离的复合人造石板及其生产方法。
为了解决上述技术问题,本发明采用的技术方案一为:
一种复合人造石板,包括基层、面层及位于基层和面层之间的中间层,所述基层为泡沫铝板层,所述面层为厚度2~20mm的人造石板层,所述中间层为玻璃纤维网格布层,所述基层通过第一胶粘剂与中间层相粘结,所述面层通过第二胶粘剂与中间层相粘结。
为了解决上述技术问题,本发明采用的技术方案二为:
一种复合人造石板的生产方法,包括以下步骤:
步骤1、用第一胶粘剂将玻璃纤维网格布粘贴在泡沫铝板上;
步骤2、用第二胶粘剂将厚度为2~20mm的人造石板粘贴于玻璃纤维网格布上;
步骤3、加压固化;
步骤4、将固化后的复合板切边,得到复合人造石板。
本发明的有益效果在于:通过在人造石板层和泡沫铝板层之间增设玻璃纤维网格布层,不仅有效解决了泡沫铝板和人造石板的热胀冷缩系数不一致导致的人造石板层易翘曲变形和人造石板层易与泡沫铝板层相互剥离的问题,而且能大幅提升复合人造石板的结构强度、抗裂性能、阻燃性能、防腐性能和消音隔热等性能,更好的满足了市场对轻薄化、高性能、低成本的复合人造石板的需求,经济效益十分显著。
