Green environment-friendly light-weight high-strength reclaimed sand and preparation process thereof
The invention relates to the technical field of reclaimed sand preparation, and particularly discloses green, environment-friendly, light and high-strength reclaimed sand and a preparation process thereof. The green, environment-friendly, light and high-strength reclaimed sand comprises basic reclaimed sand and an outer protective layer, the outer protective layer is formed by coating the basic reclaimed sand with outer protective layer raw materials, and the outer protective layer raw materials are mainly prepared from acrylic emulsion, cement, water, an elastic agent, an auxiliary agent and a waterproof agent; the preparation process comprises the following steps: (1) preparing an outer protective layer raw material: mixing the acrylic emulsion, the cement, the water, the elastic agent, the auxiliary agent and the waterproof agent, and uniformly stirring to obtain the outer protective layer raw material; and (2) preparation of reclaimed sand: mixing the basic reclaimed sand with the outer protective layer raw material, and drying to obtain the reclaimed sand. The regenerated sand prepared by the invention has few microcracks and low water absorption rate.
本申请涉及再生砂制备技术领域，具体公开了一种绿色环保轻质高强再生砂及其制备工艺。本申请的绿色环保轻质高强再生砂，包括基础再生砂和外护层，外护层由外护层原料涂覆在基础再生砂上形成，外护层原料主要由如下原料制成：丙烯酸乳液、水泥、水、弹性剂、辅助剂、防水剂；制备工艺，包括如下步骤：（1）外护层原料制备：将丙烯酸乳液、水泥、水、弹性剂、辅助剂、防水剂混合，搅拌均匀，得到外护层原料；（2）再生砂的制备：将基础再生砂与外护层原料混合，烘干得到再生砂。本申请制得的再生砂微裂纹少，吸水率低。
