Modified waste glass fiber reinforced plastic as well as preparation method and application thereof
The invention provides modified waste glass fiber reinforced plastic as well as a preparation method and application thereof, and belongs to the technical field of building materials. The surfaces of the waste glass fiber reinforced plastic particles are coated with the active inorganic mineral micro powder to serve as a shell, the shell can react in an alkaline environment to generate hydrated calcium silicate, the cohesiveness of the glass fiber reinforced plastic material and a cement base material is improved, the compatibility of the glass fiber reinforced plastic material and the cement base material is improved, and the cement material can be recycled under the condition that the influence on the volume weight and the expansion degree of the cement material is small. The mechanical property of the cement material is improved; meanwhile, the treatment problem of waste glass fiber reinforced plastics can be solved, and the method is more environment-friendly. The result of the embodiment shows that when the modified waste glass fiber reinforced plastic provided by the invention is added into a cement material, the volume weight of the material is 1.87-1.90 g/cm < 3 >, the expansion degree is 192-212 mm, the breaking strength is 7.2-7.3 MPa, the compressive strength is 38.0-40.0 MPa, and the heat conductivity coefficient is 0.45-0.48 W/(m.k).
本发明提供了一种改性废旧玻璃钢及其制备方法和应用，属于建筑材料技术领域。本发明在废旧玻璃钢颗粒表面包裹活性无机矿物微粉作为壳体，在碱性环境中可反应并生成水化硅酸钙，改善玻璃钢材料与水泥基材的粘结性，提高玻璃钢材料与水泥基材的兼容性问题，在对水泥材料的容重和扩展度影响较小的情况下，提高水泥材料的力学性能；同时能够解决废旧玻璃钢的处理问题，更加绿色环保。实施例的结果显示，将本发明提供的改性废旧玻璃钢加入到水泥材料中，材料的容重为1.87～1.90g/cm3，扩展度为192～212mm，抗折强度为7.2～7.3MPa，抗压强度为38.0～40.0MPa，导热系数为0.45～0.48W/(m·k)。
