Preparation method of inorganic artificial stone plate
The invention discloses a preparation method of an inorganic artificial stone plate. The preparation method comprises the following steps: (1) preparing recycled aggregate; (2) the recycled aggregate is soaked in a nanogel solution, and the nanogel solution circularly flows to conduct pre-strengthening treatment on the recycled aggregate; the recycled aggregate subjected to pre-strengthening treatment is subjected to liquid draining treatment, and pre-strengthened recycled aggregate is obtained; (3) stirring the pre-reinforced recycled aggregate, the new aggregate, a silicate active component, an alkali activator, water, a retarder, a water-retaining agent and a pigment to obtain a mixture; and (4) carrying out material distribution, vacuumizing, vibration pressing, maintenance, thickness determination and polishing processes on the mixture to obtain the inorganic artificial stone plate. The nano-particles continuously fill gaps of the recycled aggregate in a flowing state and are attached to the surface of the recycled aggregate in the draining process, and the nano-particles and the recycled aggregate are subjected to hydration reaction under the synergistic effect of the alkali activator and the silicate active component, so that the flexural and compressive strength of the plate is improved.
本发明公开了一种无机人造石板材的制备方法，包括以下步骤：(1)制备再生骨料；(2)将再生骨料浸泡于纳米凝胶溶液中，纳米凝胶溶液循环流动对再生骨料进行预强化处理；将预强化处理后的再生骨料进行沥液处理，得到预强化再生骨料；(3)将预强化再生骨料、新骨料、硅酸盐活性组分、碱激发剂、水、缓凝剂、保水剂及颜料进行搅拌，得到混合料；(4)将混合料通过布料、抽真空、振动压制、养护、定厚、抛光工艺得到无机人造石板材。本发明中纳米微粒在流动状态下对再生骨料空隙进行连续填充，并在沥液过程中附着于再生骨料表面，在碱激发剂、硅酸盐活性组分协同作用下纳米颗粒与其发生水化反应，从而提升板材的抗折抗压强度。
