Waste rubber particle modification method and application thereof in mortar
The invention discloses a waste rubber particle modification method and application thereof in mortar. The waste rubber particle modification method and the application of the waste rubber particle modification method in mortar are characterized in that the waste rubber particle modification method comprises the following raw materials in parts by mass: 200-400 parts of cement, 100-200 parts of water, 800-900 parts of sand, 2-8 parts of waste rubber particles, 15-30 parts of a modifier, 8-10 parts of sodium hydroxide, 8-10 parts of absolute ethyl alcohol and 5-10 parts of potassium ferrate. According to the invention, a poly (3-methoxytyramine) solution is used as a modifier, and the modification of poly (3-methoxytyramine) not only increases the polarity and oxygen-carrying groups of the rubber in principle, but also can introduce more organic functional groups to promote the combination of the rubber and a cementing material. The modified rubber is added into the mortar, the compressive strength and the breaking strength of the mortar can be improved, and the compressive strength of the rubber mortar can be improved by 35.1% and the breaking strength can be improved by 18.1% through the modification method provided by the invention.
本发明公开了一种废弃橡胶颗粒改性方法及其在砂浆中的应用。本发明包括以下质量份数的原料：一种废弃橡胶颗粒改性方法及其在砂浆中的应用，其特征在于，包括以下质量份数的原料：水泥200‑400份，水100‑200份，砂800‑900份，废弃橡胶颗粒2‑8份，改性剂15‑30份，氢氧化钠8‑10份，无水乙醇8‑10份，高铁酸钾5‑10份。本发明使用聚3‑甲氧基酪胺溶液作为改性剂，聚3‑甲氧基酪胺改性在原理上不仅是增加橡胶极性和带氧基团，更关键的是可以引入更多的有机官能团，促进橡胶和胶凝材料的结合。将改性后橡胶加入砂浆中，可以提高砂浆的抗压强度、抗折强度，本方面提出的改性方法可将橡胶砂浆的抗压强度提升35.1％，抗折强度提升18.1％。
