Mortar admixture containing waste glass fiber reinforced plastic powder and preparation method thereof
The invention discloses a mortar admixture containing waste glass fiber reinforced plastic powder and a preparation method thereof, and is characterized in that the mortar admixture comprises the following raw materials by weight: 1%-8% of cellulose ether, 1%-9% of a retarder, 2%-3% of a lubricant, 3%-7% of an air entraining agent, and 40%-80% of glass fiber reinforced plastic powder. According to the present invention, the ratio is reasonable, the preparation process is simple, the prepared reinforcing agent is used for mortar, the high value utilization of waste glass fiber reinforced plastic is achieved, and the experiment results show that the finer the waste glass powder particles are, the greater the physical filling effect is, and the mechanical crushing waste glass fiber reinforced plastic is doped in the mortar as the aggregate or the filler so as to achieve the good reinforcing effect. Fibers in the waste glass fiber reinforced plastic powder can obviously improve the bonding strength of the mortar; meanwhile, the glass fiber reinforced plastic powder contains a large amount of organic polymer materials, and the materials are filled into the mortar, so that a certain waterproof effect can be achieved.
本发明公开了一种含有废旧玻璃钢粉的砂浆外加剂及其制备方法，其特征在于，包括以下重量百分比的原料：纤维素醚1%‑8%、缓凝剂1%‑9%、润滑剂2%‑3%、引气剂3%‑7%、玻璃钢粉40%‑80%。本发明配比合理、制备工艺简单，制得的增强剂用于砂浆，实现了废玻璃钢高值化利用，于此同时，经实验得出废玻璃粉粒越细，所起到的物理填充效应越大，通过在砂浆中掺加机械粉粹的废玻璃钢作为骨料或填料，废旧玻璃钢粉体中的纤维可以明显改善砂浆的粘结强度；同时，玻璃钢粉体中含有大量的有机高分子材料，这些材料填充到砂浆中，可以起到一定的防水效果。
