Efficient anti-cracking multifunctional concrete mortar and preparation process thereof
The invention belongs to the technical field of preparation of building materials, and particularly relates to efficient anti-cracking multifunctional concrete mortar and a preparation process thereof. A device for preparing the efficient anti-cracking multifunctional concrete mortar comprises a base, a pressurizing cylinder and a crushing cylinder, wherein a first cavity is formed in the base; amotor is fixedly arranged in and connected with the first cavity; a water pumping valve is fixedly connected to the upper surface of the base; the end, located outside the first cavity, of an output shaft of the motor extends into an inner cavity of the water pumping valve; a first cam is fixedly connected to the end, located in the inner cavity of the water pumping valve, of the output shaft of the motor; a second cam is rotatably connected to the part, close to the first cam, of the inner cavity of the water pumping valve. According to the invention, waste rubber is impacted by water jet formed by strong pressure and is also impacted by sodium hydroxide and fine river sand contained in the water jet, so the waste rubber is crushed; the rubber particles are crushed by cooperatively usinga grinding disc; and finally, the modified rubber powder is added into the high-efficiency anti-cracking multifunctional concrete mortar, so the deformability of the mortar is improved.
本发明属于建筑材料制备技术领域，具体的说是高效抗裂型多功能混凝土砂浆及其制备工艺，包括底座、增压筒和粉碎筒；所述底座内部开设有第一空腔；所述第一空腔内固连有电动机；所述底座上表面固连有抽水阀；所述电动机输出轴位于第一空腔外一端延伸至抽水阀内部空腔中；所述电动机输出轴位于抽水阀内腔一端固连有第一凸轮；所述抽水阀内腔靠近第一凸轮转动连接有第二凸轮；本发明通过对废弃橡胶使用受强压形成的水射流进行冲击，并配合水射流中蕴含的氢氧化钠和细河沙，对废弃橡胶进行冲击，从而使废弃橡胶破碎，并配合碾磨盘对橡胶颗粒进行在粉碎，最终将改性橡胶粉添加至高效抗裂型多功能混凝土砂浆中，提升其可形变能力。
