High-strength stone-surface-imitating ceramic water permeable brick and preparation method thereof
The invention relates to the technical field of building materials, in particular to a high-strength stone-surface-imitating ceramic water permeable brick and a preparation method thereof. In order to reduce the production cost, a solid waste raw material is used as a main component raw material of the water permeable brick, the production cost of the ceramic water permeable brick is reduced, old soda-lime glass micro powder with a lower melting point is added as a high-temperature bonding material, and the surface of blast furnace slag is conveniently wrapped by the old soda-lime glass micro powder through infiltration of the old soda-lime glass micro powder on a ridge material; while the high-strength water permeable brick is formed, the dissolution of heavy metal elements in the blast furnace slag is avoided; in addition, the surfaces of ridge materials such as waste ceramic micro powder in the raw materials are modified, so that the rate of defective goods caused by firing is further reduced; on the basis, a self-cleaning layer is further prepared on the surface of the water permeable brick, nano silicon dioxide is loaded and sintered, the nano silicon dioxide is converted into anatase type nano silicon dioxide with high catalytic activity, the photocatalytic efficiency is improved, and degradation of the water permeable brick on organic pollutants is enhanced.
本发明涉及建筑材料技术领域，具体为一种高强度仿石面陶瓷透水砖及其制备方法；本发明为了降低生产成本，使用了固废原料作为透水砖的主要组成原料，降低陶瓷透水砖的生产成本，并添加了较低熔点的旧钠钙玻璃微粉作为高温粘接料，利用其对脊性材料的浸润，便于其包裹高炉矿渣表面，形成具有高强度的透水砖的同时，避免高炉矿渣中的重金属元素的溶出；并且本发明还对原料中的废旧陶瓷微粉等脊性材料表面进行了改性处理，进一步的降低了烧制导致的残品率；在此基础上，本发明还在透水砖表面制备了自清洁层，负载纳米二氧化硅并烧结，将其转化为具有高催化活性的锐钛矿型纳米二氧化硅，提升光催化效率，强化其对有机污染物的降解。
