Method for preparing baking-free brick from waste silicon rubber cracking residues and application of baking-free brick
The invention discloses a method for preparing a baking-free brick by using waste silicon rubber cracking residues and application of the baking-free brick. The method comprises the following steps: adding quick lime into the silicon rubber cracking residues, uniformly mixing, standing for 3-5 days, carrying out vacuum heating, condensing gas distilled in the heating process by using a condenser, recovering liquid, and cooling to room temperature after the reaction is finished to obtain secondary residues; grinding the secondary residues, and mixing the ground secondary residues with cement, quick lime, yellow sand, water and an additive to obtain mortar; pouring the mortar into a mold, and pressing into a baking-free brick blank; covering the baking-free brick blank with wet rag for natural curing, and then performing autoclaved curing in an autoclave to obtain the baking-free brick. According to the invention, the secondary silicon rubber cracking slag can be directly used as a main raw material of the baking-free brick without high-temperature calcination, so that the treatment cost of an enterprise is greatly reduced, the environmental pollution is avoided, certain economic benefits and social benefits are generated, the practical popularization and application value is extremely high, and meanwhile, the cultivated land resource can be effectively protected.
本发明公开了一种利用废旧硅橡胶裂解渣制备免烧砖的方法及其应用，方法包括：在硅橡胶裂解残渣中加入生石灰，混匀后放置3‑5天，真空加热，加热过程中蒸馏出的气体用冷凝器冷凝后回收液体，反应完毕后冷却至室温得到二次残渣；将二次残渣研磨后与水泥、生石灰、黄砂、水、外加剂混合，得到砂浆；将砂浆倒入模具中，压制成免烧砖胚；将免烧砖胚用湿抹布覆盖自然养护，之后在蒸压釜内蒸压养护，即得免烧砖。本发明可将二次硅橡胶裂解渣在不经过高温煅烧而直接作为免烧砖的主要原料，大大降低了企业处理成本，既避免了环境污染，又产生了一定的经济效益和社会效益，有极强的实际推广应用价值，同时也能有效保护耕地资源。
