Description

一种免烧结的填充式真空石和制备工艺 技术领域
本发明涉及一种免烧结的填充式真空石，同时涉及一种免烧结的填充式真空石制备工艺。
背景技术
天然石材作为建筑材料的重要部分，因为其色彩多样化，开发容易，自古以来一直被人广泛使用。但是随着其开采量的过度增加，开采利用率低等原因，天然石材的开采逐步受到限制，特别是欧洲国家，已经禁止了天然石材的开采。而且每个矿产区的产品，其花色，品种都是独一的，更增加了其使用上的难度。人们一直在寻找其替代品。随着经济的发展，建筑装饰材料日新月异，合成石作为一种新型的装饰材料得到很大的发展机遇。但现有技术中的合成石通常有颗粒骨料和粘结剂混合压制而成，例如中国专利号为CN200910215153.7号发明专利，公开日为2011年5月11日，公开了一种人造石英石板材的制备工艺，其特征在于，它包括如下工艺步骤：a、配料，通过自动配料系统将石英砂、石英粉、玻璃、大理石颗粒、不饱和树脂、色粉、固化剂和偶联剂按比例混合，并送进星式搅拌机高速搅拌，充分搅拌后直接将料卸落在预置的模框中，将料布平，再铺上纸皮；b、通过多层叠板机将多张板叠起；c、压制、中温固化，由多层叠板压机压制成型，使用升降式固化炉，采用三块铁板夹加两块板材的固化方式，通过恒温导热油均匀加热传导，使板材均匀收缩固化；d、抛光、切割、包装。在所述工艺步骤a过程中，采用的主要原料及辅料配比(按重量百分比算)包括石英砂10～40％、石英粉28～36％、玻璃5～45％、大理石颗粒5～15％、不饱和树脂8～12％、色粉0.1～0.4％、固化剂和偶联剂0.04～0.5％。通过上述专利可以看出，现有技术中的配料过程中是将粘结剂(树脂)与骨料一起混合， 其本质是通过粘结剂将各个骨料粘结在一起，合成石的强度是由粘结剂来决定的。但这种粘结结合方式受粘结强度的限制，合成石的强度很难提高。另外，为了能够将所有骨料粘结在一起，需要使用较多的树脂，增加了树脂的使用量，树脂使用量的增加不仅降低了合成石的强度，而且还带来了环保问题。

按照本发明提供的一种免烧结的填充式真空石和制备工艺与现有技术相比具有如下优点：本发明采用一种全新的制备工艺，将小粒径颗粒骨料填充到大粒径颗粒骨料的缝隙中，再将细小粒径颗粒骨料填充到小粒径颗粒骨料的缝隙中，细小颗粒骨料的缝隙则由液体填充剂填充，利用大小颗粒之间的相互填充，尽量将所有缝隙填实，将颗粒骨料之间的缝隙中的空气排出，形成真空密闭体，即利用马德堡半球原理，形成真空石，本发明的真空石强度不取决于粘结剂的粘结强度，而是由填充的密实程度决定，可以有效的提高真空石的强度。本发明中的液体填充剂仅与细粒径固体颗粒混合，因此使用量较小，不仅环保，而且方便搅拌加工。
附图说明
图1是本发明的结构示意图。
具体实施方式
为清楚的说明本发明中的方案，下面给出优选的实施例并结合附图详细说明。以下的说明本质上仅仅是示例性的而并不是为了限制本公开的应用或用途。应当理解的是，在全部的附图中，对应的附图标记表示相同或对应的部件和特征。
参见图1，本发明提供的一种免烧结的填充式真空石，所述真空石包括不同粒径的颗粒骨料2和基准体积的填充单元体1，所述填充单元体1由细粒径固体颗粒填充料11和液体填充剂制成，所述固体颗粒填充料11的表面具有由所述液体填充剂填充形成的柔性液体填充膜12，各粒径的所述颗 粒骨料2互相填充贴合，所述颗粒骨料2之间的缝隙填充有所述填充单元体1，形成真空密闭体。
本发明中的填充单元体1，是将细粒径固体颗粒填充料11与液体填充剂混合，使所述固体颗粒填充料的表面形成柔性液体填充膜12；本发明中的细粒径固体颗粒填充料为最小粒径填充单元，所述柔性液体填充膜12具有外形可塑特性，在填充过程中能够根据缝隙的大小变化形状，从而适用大小不同的缝隙，将缝隙填充密实。
本发明将不同粒径的颗粒骨料2相互填充，大粒径颗粒骨料相互接近贴合，小粒径颗粒骨料填充大粒径颗粒骨料之间的缝隙，各粒径颗粒骨料之间的缝隙由填充单元体填充，所述填充单元体在填充的过程中，其表面的柔性液体填充膜根据缝隙的大小形状发生变形，从而尽可能将所有缝隙均填充密实，排出缝隙中的空气。本发明利用马德堡半球的原理制备出真空石，该真空石更接近于自然界中天然石材，真空石的整体性能也接近于天然石材。
现有技术中的合成石均是利用粘结剂将各粒径的颗粒骨料粘结在一起，不仅合成石的强度不高，而且不够环保。本发明的真空石是利用大气压强将各粒径颗粒骨料压在一起，强度更高，也更环保。本发明提出的填充概念是指各粒径颗粒骨料相互运动贴合，并由次一级粒径的颗粒骨料填充大一级粒径的颗粒骨料缝隙，最终由填充单元体完成所有缝隙的填充。本发明的真空石不同于现有技术中的合成石。本发明为了实现填充目的，各粒径颗粒骨料不与液体填充剂混合，各粒径颗粒骨料能够更好的相互贴合，也降低了液体填充剂的使用量。所述液体填充剂只与细粒径固体颗粒填充料混合，制成最小粒径的基准体积填充单元体，制备完成的所述填充单元体再用于颗粒 骨料的混合，使所述填充单元体包裹各粒径的颗粒骨料，包裹填充单元体的颗粒骨料在成型过程中能够更好的相互填充，它们之间的缝隙则由填充单元体填充，最终形成真空密闭体。若各粒径颗粒骨料表面包裹粘结剂，则在压制过程中，细粒径颗粒骨料难以填充进颗粒骨料的缝隙中。粘结剂使用过多，在压制过程中，多余的粘结剂很难从合成石排出，最终形成的就是由粘结剂粘结形成的合成石结构，粘结剂的粘结强度决定了合成石的强度。同时，本发明也无需对真空石进行烧结，是一种免烧结产品，更加环保。因此，本发明提出的真空石是一种全新产品。
本发明中的所述颗粒骨料在真空力和高频重锤拍击力的合力作用下互相运动填充，并将所述填充单元体填充到各所述颗粒骨料的缝隙中。本发明中真空力和重锤拍击力是由发明人所拥有的重锤拍击式合成石成型机设备实现的，参见中国专利申请号为201510026692.1的发明专利申请。
本发明的真空石采用以下制备工艺制得，该制备工艺包括以下步骤，
制备填充单元体，将细粒径固体颗粒填充料与液体填充剂混合，使所述固体颗粒填充料的表面形成柔性液体填充膜；本发明中的细粒径固体颗粒填充料为最小粒径填充单元，所述柔性液体填充膜具有外形可塑特性，在填充过程中能够根据缝隙的大小变化形状，从而适用大小不同的缝隙，将缝隙填充密实。
混料，将不同粒径的颗粒骨料与所述填充单元体混合，制成混合料；
成型，所述颗粒骨料在真空力和重锤拍击力的合力作用下互相运动填充，并将所述填充单元体填充到各所述颗粒骨料的缝隙中，形成真空密闭体。本发明中真空力和重锤拍击力是由发明人所拥有的重锤拍击式合成石成型机设备实现的，参见中国专利申请号为201510026692.1的发明专利申请。 利用该设备可以将不同粒径的颗粒骨料相互填充，大粒径颗粒骨料相互接近贴合，小粒径颗粒骨料填充大粒径颗粒骨料之间的缝隙，各粒径颗粒骨料之间的缝隙由填充单元体填充，所述填充单元体在填充的过程中，其表面的柔性液体填充膜根据缝隙的大小形状发生变形，从而尽可能将所有缝隙均填充密实，排出缝隙中的空气。本发明利用马德堡半球的原理制备出真空石，该真空石更接近于自然界中天然石材，真空石的整体性能也接近于天然石材。本发明提出的制备工艺是一种全新工艺。
参见图1，在本发明给出的上述实施例中进一步包括，所述固体颗粒填充料与所述液体填充剂的用量由以下条件确定：
Q液体＝(ρ固体-ρ颗粒压实)/ρ固体×1cm3×ρ液体
Q固体＝ρ颗粒压实×1cm3
式中：Q液体为用1吨的压力对一平米厘米面积的填充单元体进行施压，最终获得一立方厘米的填充单元体中的液体填充剂基准用量 单位g，该参数是作为液体填充剂所占比例的参考数值，即最佳量。实际在制备过程中，该参数为选料提供了参考值，通过上述公式确定了该参数的数值，根据制备填充单元体的体积换算相应用量。该用量可以在参考值的基础上进行调整，从而简化各物料的配比工作，降低物料损耗。
Q固体为用1吨的压力对一平米厘米面积的填充单元体进行施压，最终获得一立方厘米的填充单元体中的固体颗粒填充料基准用量 单位g该参数是作为固体颗粒填充料所占比例的参考数值，即最佳量。实际在制备过程中，该参数为选料提供了参考值，通过上述公式确定了该参数的数值，根据制备填充单元体的体积换算相应用量。该用量可以在参考值的基础上进行调整，从而简化各物料的配比工作，降低物料损耗。
ρ固体为固体颗粒填充料的实际密度单位g/cm3，该参数由所采用固体颗粒的材质决定，若采用多种不同材质的固体颗粒，则通过各不同材质固体颗粒所占比例进行计算，最终得出。比如石英石的实际密度为2.65g/cm3。
ρ颗粒压实为用1吨的压力对一平米厘米面积固体颗粒填充料进行施压，最终获得一立方厘米的固体颗粒填充料的质量 单位g/cm3，该参数可以通过实验获得，采取不同材质的固体颗粒填充料分别压制，然后称重来获得。
ρ液体为液体填充剂的实际密度 单位g/cm3，该参数由所采用的液体填充剂来决定，比如不饱和树脂的密度在1.4-2.2g/cm3。
在本发明给出的上述实施例中，如果采用石英石作为细粒径固体颗粒填充料，采用不饱和树脂作为液体填充剂。首先，对细粒径石英石按照一平米厘米用1吨的压力标准进行压制，压制完成后，取一立方厘米进行称重，最终获得参数为ρ颗粒压实＝1.91g/cm3。因此，Q固体＝ρ颗粒压实×1cm3＝1.91g。Q液体＝(ρ固体-ρ颗粒压实)/ρ固体×1cm3×ρ液体＝(2.65-1.91)/2.65×1×2＝0.56g。即参考值是压制一个立方厘米的填充单元体需要石英石1.91g，不饱和树脂0.56g，按照该比例关系进行配比即可。
参见图1，在本发明给出的上述实施例中进一步包括，所述颗粒骨料与所述填充单元体的用量由以下条件确定：
Q单元体＝(ρ骨料-ρ骨料压实)/ρ骨料×1cm3×ρ单元体
Q骨料＝ρ骨料压实×1cm3
式中：Q单元体为一立方厘米的真空石中的填充单元体基准用量 单位g，该参数是作为填充单元体所占比例的参考数值，即最佳量。实际在制备过程中，该参数为选料提供了参考值，通过上述公式确定了该参数的数值，根据制备真空石的体积换算相应用量。该用量可以在参考值的基础上进行调整， 从而简化各物料的配比工作，降低物料损耗。
Q骨料为一立方厘米的真空石中的颗粒骨料基准用量 单位g，该参数是作为颗粒骨料所占比例的参考数值，即最佳量。实际在制备过程中，该参数为选料提供了参考值，通过上述公式确定了该参数的数值，根据制备真空石的体积换算相应用量。该用量可以在参考值的基础上进行调整，从而简化各物料的配比工作，降低物料损耗。
ρ骨料为颗粒骨料的实际密度 单位g/cm3，该参数由所采用颗粒骨料的材质决定，若采用多种不同材质的颗粒骨料时，则通过各不同材质颗粒骨料所占比例进行计算，最终得出。比如石英石的实际密度为2.65g/cm3。
ρ骨料压实为用1吨的压力对一平米厘米面积的颗粒骨料进行施压，最终获得一立方厘米的颗粒骨料的质量 单位g/cm3，该参数可以通过实验获得，采取不同材质的颗粒骨料分别压制，然后称重来获得。
ρ单元体为填充单元体的实际密度 单位g/cm3该参数是以下公式确定：
ρ单元体＝(Q液体+Q固体)/1cm3
。其中Q液体和Q固体与前述内容一致。
在本发明给出的上述实施例中，如果采用石英石作为颗粒骨料。首先，将不同粒径的颗粒骨料混合按照一平方厘米用1吨的压力标准进行压制，压制完成后，取一立方厘米的颗粒骨料进行称重，最终获得参数ρ骨料压实＝2.0g/cm3。Q骨料＝ρ骨料压实×1cm3＝2.0g。ρ单元体＝(0.56g+1.91)/1＝2.47g/cm3,Q单元体＝(ρ骨料-ρ骨料压实)/ρ骨料×1cm3×ρ单元体＝(2.65-2.0)/2.65×1×2.47＝0.60g。即参考值是压制一个立方厘米的真空石需要填充单元体0.60g，石英石颗粒骨料2.0g，按照该比例关系进行配比即可。
参见图1，在本发明给出的上述实施例中进一步包括，所述固体颗粒填充料与所述液体填充剂通过搅拌混合，重量比例为2-6：1。通过上述填充单元体各组分公式得到参考值，可以在该比例关系内进行调整，只要满足该比例关系均可以。该比例关系也可以对公式计算的参考值进行验证，确定是否符合要求。本实施例由上述公式确定的比例为3.4:1。
参见图1，在本发明给出的上述实施例中进一步包括，在成型步骤之前还包括有布料，将所述混合料布置成板状结构。布料可以由布料机进行布料，布料时要使得填充单元体与颗粒骨料分布均匀，利于成型步骤的填充运动。
参见图1，在本发明给出的上述实施例中进一步包括，在成型步骤之后还包括有固化，将所述液体填充剂由液态变为固态。本发明所述的液体填充剂是指具有由液态转化为固态特性的液体，这种液体还需要在常态情况下长期保持固态，从而消除缝隙中的空气，使空气不易进入缝隙中，比如树脂等。
参见图1，在本发明给出的上述实施例中进一步包括，所述固体颗粒填充料的粒径为0.1mm-0.01mm，本实施例采用0.05mm，所述颗粒骨料的粒径为0.1mm以上。本发明中的颗粒骨料的粒径是按照需要选择不同粒径的颗粒骨料，0.1mm以上并不是没有限制的，所述颗粒骨料粒径的选择适用于本领域各种不同材质骨料大小，本领域技术人员可以按照真空石的具体结构来进行选择。
参见图1，在本发明给出的上述实施例中进一步包括，所述液体填充剂可以具有由液态变为固态的特性，包括有机类树脂和无机类树脂。所述有机类树脂包括亚克力树脂、不饱和树脂、丙烯类树脂或环氧树脂，无机类树脂包括大豆基树脂或橡胶类树脂。这些液体填充剂具有由液体向固态转化的特性，并能够满足真空石的需要。本发明所述的液体填充剂是指具有由液态 转化为固态特性的液体，这种液体还需要在常态情况下长期保持固态，从而消除缝隙中的空气，使空气不易进入缝隙中，比如上述的各种树脂等，这些树脂自身或在催化剂的作用下由液态转化为固态。
综上所述，以上所述内容仅为本发明的实施例，仅用于说明本发明的原理，并非用于限定本发明的保护范围。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
