2)基材切片,切片厚度15mm至50mm,按需求厚度选择切片厚度,备用;
3)第一次布网,玻纤网格布及砂浆A,玻纤网格布采用每平方米140克规格,用砂浆A 背网;养护,所述砂浆A配比为PC52.5白水泥20份-35份,70份-120目石英砂40份-60 份,40-70目石英砂10份-25份,可再分散乳胶粉2份-3.5份,十万粘度纤维素醚0.2份-0.5 份,减水剂0.15份-0.5份;
4)第二次背面布网,玻纤网格布采用每平方米140克规格,同样采用砂浆A背网,养护;
5)选择首次布网的一面,涂布砂浆B,布料厚度2至4毫米,砂浆B配比为PC52.5白水泥25到35份,70到120目石英砂40到70份,40到70目石英砂10到25目,可再分散乳胶粉2到5份,400粘度纤维素醚0.2到0.4份,减水剂0.15到0.5份;
6)成型:养护完成后,选择涂布了砂浆B的一面,定厚、抛光、表面孔洞修补、烘干、打印,烘干,然后喷涂无机涂料,再进烘干线烘干,喷涂自清洁涂层,烘干,覆膜包装成型,即可。
本发明的有益效果是:本发明轻质石材,添加堆积密度在300千克每立方米以下的改性玻化微珠,基材密度只有400到800千克每立方米,加工成型后轻质石材的密度为450到1000 千克每立方米,而常规石材密度为2600到2800千克每立方米,通过在基材正反面涂布本发明配制的砂浆A,以及首次布网的一面涂布砂浆B及玻纤网格布的布置,最终制得具有轻质、高韧性、抗拉伸的环保型石材。
具体实施方式
为使本公开实施例的目的、技术方案和优点更加清楚,下面对本公开实施例的技术方案进行清楚、完整地描述。显然,所描述的实施例是本公开的一部分实施例,而不是全部的实施例。基于所描述的本公开的实施例,本领域普通技术人员在无需创造性劳动的前提下所获得的所有其他实施例,都属于本公开保护的范围。
在一个实施例中,本发明的一种轻质人造石材的制备,包括以下步骤:
1)制备干粉预拌砂浆,称取如下重量份的原材料:改性玻化微珠40份,标号为PC-52.5 的白水泥55份,硅微粉2份,助剂1份,本实施例的助剂包括羟丙基甲基纤维素0.4份,减水剂0.6份,加水混合均匀,水与混合物的比例为(0.3-0.4):1,混合,模具成型,自然养护,得到基材,备用;
2)基材切片,切片厚度15mm至50mm,按需求厚度选择切片厚度,备用;
3)第一次布网,玻纤网格布及砂浆A,玻纤网格布采用每平方米140克规格,用砂浆A 背网;养护,所述砂浆A配比为PC-52.5白水泥30份,50目石英砂50份,50目石英砂20 份,可再分散乳胶粉3份,十万粘度纤维素醚0.3份,减水剂0.3份;
4)第二次背面布网,玻纤网格布采用每平方米140克规格,同样采用砂浆A背网,养护;
5)选择首次布网的一面,涂布砂浆B,布料厚度2至4毫米,砂浆B配比为PC-52.5白水泥30份,100目石英砂50份,50目石英砂20份,可再分散乳胶粉3份,400粘度纤维素醚0.3份,减水剂0.3份;
