Method for improving microwave curing efficiency of artificial stone
The invention discloses a method for improving microwave curing efficiency of artificial stone, which comprises the following steps: uniformly mixing a vinyl silane coupling agent, low alcohol and deionized water, adjusting the pH value to 4-6 by using glacial acetic acid, preparing a silane hydrolysis solution, adding silicon carbide into the silane hydrolysis solution, stirring for reaction, standing, and filtering to obtain modified silicon carbide particles; washing to remove redundant vinyl silane on the surfaces of the silicon carbide particles, heating and curing the modified silicon carbide particles, and cooling to normal temperature for later use; marble particles and modified silicon carbide particles are evenly mixed to obtain aggregate, then a binder and an auxiliary are added into the aggregate to be stirred into a cluster, then the cluster is injected into a mold, and uncured artificial stone quarry stone is obtained through vacuum vibration compression molding; and curing the artificial stone block under a microwave condition to obtain the artificial stone. The heating rate of the artificial stone in microwave treatment is effectively improved, so that the curing time is shortened, the energy consumption is reduced, and meanwhile, the mechanical strength of the artificial stone is improved.
本发明公开了一种提高微波固化人造石效率的方法，其先将乙烯基硅烷偶联剂、低级醇和去离子水混合均匀，用冰醋酸调节pH至4~6后配制硅烷水解溶液，接着再将碳化硅加入硅烷水解溶液中搅拌反应、静置后过滤得到改性碳化硅颗粒，然后洗涤以去除碳化硅颗粒表面多余的乙烯基硅烷，再将改性碳化硅颗粒加热固化，冷却至常温后备用；将大理石颗粒、改性碳化硅颗粒混合均匀得到骨料，然后向骨料中加入粘结剂和助剂搅拌成团，再将其注入模具中，通过真空振动压制成型得到未固化的人造石荒料；将人造石荒料置于微波条件下固化即可得到人造石。本发明有效提高了人造石在微波处理中的升温速率，从而缩短固化时间，减少能源消耗，同时提高人造石的机械强度。
