The road with ceramic aggregate, consists of the following: the weight ratio of the raw materials of SiO: 2, Al: 55-60% 2 O: 3, K: 25-30% 2 O47%, Li: 2 O35%, CaO0.10.6%, MgO25%, Fe: 2 O: 3 and above accounted for 0.10.8% the total weight of the inorganic ceramic pigment ingredients 3 province. The ceramic aggregate is sintered at low temperature. The invention is designed for raw material formula of low temperature fast firing, low cost of raw materials, simple production process and high efficiency than the original technology, low sintering temperature 150 to 200 DEG C, greatly saves energy, the firing cycle shortened to 4 hours to 6 hours, the burning rate increased from the original 80% to 98%. Lower than 1% aggregate water absorption rate, good thermal stability, in the cold and hot cracks, high strength, good wear resistance, the wear rate is less than 13%, the proportion of 2.2 - 2.8g / cm = 3, high impact strength.
【技术实现步骤摘要】
本专利技术属于铺设路面用的添加材料,具体涉及一种。
技术介绍
筑路铺面材料目前一般采用沥青或水泥,所用的骨料基本为石灰石或碎石子,这种骨料硬度低,易风化,耐磨度差,耐腐蚀性低,属天然形成,颜色单调。专利文献中公开了采用二氧化硅、三氧化铝为主要原料的骨料组成,以替代石子,在强度、耐磨、耐腐蚀性等方面提高了性能,但配方中SiO2的含量较多,产品的抗冲击强度较差;金属氧化物含量少,烧制温度较高,耗能多,热稳定性比较差。在制造工艺上,存在效率低,能耗高等缺点。
技术实现思路
本专利技术所要解决的技术问题是提供一种抗冲击强度高、热稳定性好、耐磨性好,生产效率高,耗能降低的筑路用陶瓷骨料及其制造方法。本专利技术筑路用陶瓷骨料,其特征在于由下列重量配比的原料组成SiO255-60%、Al2O325-30%、K2O 4-7%、Li2O 3-5%、CaO 0.1-0.6%、MgO 2-5%、Fe2O30.1-0.8%和占上述配料总重量3-5%的无机陶瓷颜料。SiO2与Al2O3是主要成分,对产品耐腐蚀性很重要,但含量过多则会提高烧成温度,明显增加能耗,含量过低则会降低耐腐蚀和耐磨性 ...
