Special high-thixotropy type sprayed concrete additive suitable for high geothermal condition and preparation method of special high-thixotropy type sprayed concrete additive
The invention relates to the field of building materials, and particularly discloses a special additive for high thixotropic sprayed concrete suitable for a high geothermal condition and a preparation method of the special additive, and the special additive is prepared from raw materials including a monomer A, a monomer B, a monomer C, a pillared material and an initiator; the monomer A, the monomer B and the monomer C are used as polymerization monomers to be subjected to intercalation reaction with the pillared material to obtain a modified pillared material; the monomer C is p-amino styrene or a substance containing an amino group and a phenyl structure of an unsaturated bond; the structure of the monomer A is shown as a formula (I); in the formula, R1 represents H or-CH3, R2 represents H or-CH3, and R3 represents H or-CH3; the structure of the monomer B is as shown in a formula (II): # imgabs 1 #, wherein R2/R2'represents H or-CH3. According to the additive disclosed by the invention, the sprayed concrete not only has good pumping performance, but also has proper rebound rate and good early strength, and the sprayed concrete has proper expansion degree.
本申请涉及建筑材料领域，具体公开了一种适用于高地热条件下的高触变型喷射混凝土专用添加剂及其制备方法，专用添加剂由包括单体A、单体B、单体C、柱撑材料、引发剂的原料制成；所述单体A、单体B和单体C作为聚合单体和柱撑材料进行插层反应得到改性柱撑材料；所述单体C为对氨基苯乙烯或者为含氨基和不饱和键的苯基结构的物质；所述单体A的结构如式(I)所示；#imgabs0#其中，R1代表H或‑CH3；所述单体B的结构如式(II)所示：#imgabs1#其中，R2/R2′代表H或‑CH3。本申请的添加剂使得喷射混凝土不仅具有良好的泵送性能，而且具有合适的回弹率，早期强度好，并且喷射混凝土具有合适的扩展度。
