Preparation method of environment-friendly colored concrete
The invention belongs to the technical field of concrete, and provides an environment-friendly colored concrete preparation method, which comprises: 1, soaking a recycled aggregate in a silane coupling agent ethanol solution, and drying to obtain a modified aggregate; 2, adding the styrene-isoprene soft segment block copolymer, waste rubber, a compatilizer, a polymerization initiator, a rubber accelerator and an antioxidant into an internal mixer, and mixing for 20-30 minutes to obtain a thermoplastic elastomer asphalt modifier; step 3, injecting a thermoplastic elastomer asphalt modifier, coumarone resin, an organic pigment and a 5wt% emulsifier aqueous solution into an emulsifying machine for emulsifying at the emulsifying temperature of 100-120 DEG C to obtain a colored cementing material; the waste concrete is reprocessed and then used as aggregate, and waste rubber is used as a raw material in modification of asphalt, so that the waste concrete and the waste rubber can be recycled.
本发明属于混凝土技术领域，提供了一种环保型彩色混凝土制备方法，包括以下步骤：步骤一：将再回收骨料浸泡在硅烷偶联剂乙醇溶液并干燥，得到改性骨料；步骤二：将苯乙烯‑异戊二烯软段的嵌段共聚物、废旧橡胶、相容剂、聚合引发剂、橡胶促进剂和抗氧剂投入到密炼机中混炼20‑30min，得到热塑性弹性体沥青改性剂；步骤三：将热塑性弹性体沥青改性剂、香豆酮树脂、有机颜料和5wt％的乳化剂水溶液注入到乳化机中乳化，乳化温度为100～120℃，得到彩色胶结料；将废旧混凝土再加工后作为骨料再次使用，在对沥青的改性中采用废旧橡胶作为原料，能够对废旧混凝土和废旧橡胶起到回收再利用的作用。
