High-strength rubber mortar material and preparation method thereof
The invention provides a high-strength rubber mortar material and a preparation method thereof, and belongs to the technical field of rubber mortars.The high-strength rubber mortar material is prepared from, by weight, 80-120 parts of cement, 240-350 parts of sand, 50-65 parts of water, 0.5-1 part of a water reducing agent and 1-12 parts of alkaline microbeads, a shell material of the alkaline microbeads is prepared from 18-22 parts of chitosan, 0.1-1 part of polyvinylpyrrolidone, 1-3 parts of an emulsifier, 18-22 parts of water and 18-22 parts of acetic acid, and the shell material of the alkaline microbeads is prepared from the following raw materials of water, water and water. The core material comprises 0.1-1 part of an initiator, 1-3 parts of rubber powder, 0.5-2 parts of an emulsifier, 18-22 parts of water and 18-22 parts of acetic acid. The rubber is wrapped in the microbead shell, agglomeration of the rubber powder in the mortar preparation process can be avoided, the emulsion is prepared through ultrasonic waves, the porosity of the mortar is effectively reduced, the problem that cement hydration is affected by the rubber powder is solved, the strength of a rubber mortar product is improved, and recycling of waste rubber is achieved.
本发明提供一种高强度的橡胶砂浆材料及其制备方法，属于橡胶砂浆技术领域，按重量份计，原料包括水泥80～120份、砂子240～350份、水50～65份、减水剂0.5～1份、碱性微珠1～12份，所述碱性微珠的壳材包括壳聚糖18～22份、聚乙烯吡咯烷酮0.1～1份、乳化剂1～3份、水18～22份、醋酸18～22份，核材包括引发剂0.1～1份、橡胶粉1～3份、乳化剂0.5～2份、水18～22份、醋酸18～22份。本发明将橡胶包裹在微珠壳体内，可避免砂浆制备过程中橡胶粉发生团聚，并采用超声波制备乳液，有效降低砂浆的孔隙率，解决了橡胶粉影响水泥水化的问题，提高橡胶砂浆制品的强度，实现了废旧橡胶的回收利用。
