Description
技术领域
本发明涉及复合衬板技术领域,尤其是涉及一种复合衬板及复合衬板的安装方法。
背景技术
在散料输送过程中,物料与局部设备之间有时存在强烈的摩擦和冲击作用,若输送的物料硬度较大(如烟煤、无烟煤、砂石、铁矿石等),将导致设备或部件快速损耗,设备更换或维修量较大,工程应用上的解决方案多在迎料面或摩擦面上安装可更换的耐磨耐冲击衬板。衬板广泛应用于带式输送机头部漏斗、斗轮机溜料槽、破碎机、球磨机等领域。目前常用衬板大多数是采用高铬铸铁、高锰钢、不锈钢、耐磨陶瓷、高分子聚乙烯、聚氨酯等材料制成整体板材,然后固定于要保护的设备或部件上。上述类型的衬板或性能欠佳,或不阻燃,或难以安装更换,或成本太高,难以达到一个理想的技术、经济平衡点。
CN202702705U公开了一种橡胶陶瓷复合衬板,橡胶陶瓷复合衬板为橡胶基板的上表面设置有与之硫化为一体的陶瓷耐磨块。陶瓷耐磨性好,但不耐冲击、易脱落,而将陶瓷设计成小块直接硫化到橡胶基板上表面,橡胶基板的柔软性好,可缓解冲击力,大大增强了衬板的抗冲击性能,陶瓷耐磨块与橡胶基板直接硫化为一体,又解决了陶瓷易脱落现象,使得橡胶陶瓷复合衬板耐冲击、耐磨损。该技术方案中陶瓷与橡胶采用硫化结合,工艺比较复杂;橡胶底板采用整块加强钢板,增加了衬板重量和成本。
发明内容
为了克服现有技术的缺陷,本发明解决的技术问题在于:提供一种能耐磨、耐冲击、耐腐蚀、阻燃,且成本低、使用寿命长、易于制造安装更换的复合衬板及复合衬板的安装方法。
为了解决上述技术问题,一方面,本发明提供一种复合衬板,它包括发泡橡胶层;至少一块粘合在所述发泡橡胶层表面上的微晶玻璃面板;至少一块嵌入所述发泡橡胶层内与发泡橡胶硫化在一起的钢板。
作为优选技术方案,本发明提供的复合衬板,所述微晶玻璃面板的长度为200~300mm,宽度为150~250mm,厚度为10mm。
作为优选技术方案,本发明提供的复合衬板,所述发泡橡胶层的厚度为10mm。
作为优选技术方案,本发明提供的复合衬板,所述钢板的长度为100mm,宽度为100mm,厚度为5mm。
作为优选技术方案,本发明提供的复合衬板,所述钢板和发泡橡胶层设有安装螺栓的通孔。
作为优选技术方案,本发明提供的复合衬板,相邻两微晶玻璃面板之间留有5~10mm的间隙。
为了解决上述技术问题,另一方面,本发明提供一种复合衬板的安装方法,所述复合衬板包括发泡橡胶层;至少一块粘合在所述发泡橡胶层表面上的微晶玻璃面板;至少一块嵌入所述发泡橡胶层内与发泡橡胶硫化在一起的钢板,安装过程包括以下步骤:
在需要保护的母板上合适的位置开孔;
在有钢板的发泡橡胶层处也开出与所述母板上的开孔相匹配的螺栓孔;
用螺栓将发泡橡胶层连接在母板上;
至少在发泡橡胶层的上表面涂上粘合剂;
在涂有粘合剂的发泡橡胶层的上表面粘贴微晶玻璃面板;粘贴过程中使相邻两微晶玻璃面板之间留有5~10mm的间隙。本方案中还可在微晶玻璃面板的一面也涂上粘合剂;
作为优选技术方案,本发明提供的复合衬板的安装方法,所述粘合剂为双组分环氧树脂粘合剂,包括A、B组分,A组分为经过SiO2和SiC改性的环氧树脂,B组分是胺类固化剂或眯唑类固化剂。
在上述优选方案的基础上,作为进一步优选技术方案,本发明提供的复合衬板的安装方法,所述A组分中的环氧树脂为加入其用量1wt%~3wt%纳米SiO2和1wt%表面改性纳米SiC改性后的环氧树脂。在环氧树脂中加入纳米SiO2和表面改性纳米SiC可以增强粘合剂的韧性和耐磨性,延长复合衬板的使用寿命。
在不冲突的情况下上述优选方案可单独或组合实施。
本发明提供的技术方案,采用微晶玻璃面板,具有耐磨、耐冲击、耐腐蚀、阻燃,对物料的适应性比较强的优点;发泡橡胶具有缓冲作用,能够缓解物料对冲击面的直接撞击,降低运动状态物料的速度,从而利于控制由于物料流动而产生的粉尘;综合成本较低,寿命较长,且易于安装和更换。
附图说明
附图用来提供对本发明的进一步理解,构成本申请的一部分,本发明的示意性实施例及其说明用于解释本发明,并不构成对本发明的不当限定。在附图中:
图1是实施例复合衬板的主视结构示意图;
图2是实施例复合衬板的后视结构示意图;
图3是实施例复合衬板的剖面结构示意图。
具体实施方式
下面结合附图对本发明的具体实施方式作进一步详细的说明。
如图1至图3所示的复合衬板,包括厚度为10mm的发泡橡胶层2,若干块长度为200~300mm,宽度为150~250mm,厚度为10mm的微晶玻璃面板1粘合在发泡橡胶层2表面上,相邻两微晶玻璃面板1之间留有5~10mm的间隙,四块长度为100mm,宽度为100mm,厚度为5mm的钢板3嵌入发泡橡胶层2内并与发泡橡胶硫化在一起,钢板3和发泡橡胶层2设有安装沉头螺栓4的通孔。
复合衬板的安装过程包括以下步骤:在需要保护的母板5上与发泡橡胶层2中钢板3的通孔相应位置开出相匹配的螺栓孔,用沉头螺栓4将发泡橡胶层2连接在母板5上,至少在发泡橡胶层2的上表面涂上粘合剂,在涂有粘合剂的发泡橡胶层2的上表面粘贴微晶玻璃面板1,粘贴过程中使相邻两微晶玻璃面板1之间留有5~10mm的间隙。粘合剂为双组分环氧树脂粘合剂,包括A、B组分,A组分为加入环氧树脂量1wt%~3wt%纳米SiO2和1wt%表面改性纳米SiC改性后的环氧树脂,B组分是胺类固化剂或眯唑类固化剂。在环氧树脂中加入纳米SiO2和表面改性纳米SiC可以增强粘合剂的韧性和耐磨性,延长复合衬板的使用寿命。
显然,本发明不限于以上优选实施方式,还可在本发明权利要求和说明书限定的精神内,进行多种形式的变换和改进,能解决同样的技术问题,并取得预期的技术效果,故不重述。本领域的普通技术人员能从本发明公开的内容直接或联想到的所有方案,只要在权利要求限定的精神之内,也属于本发明的保护范围。
