摘要
由废弃聚酯饮料瓶经醇解、缩聚后，制得低成本的再生型不饱和聚酯，用它制得了早强型聚合物改性水泥砂浆，该砂浆早期抗折强度及与普通水泥试块之间的早期粘接强度，均大大优于普通水泥砂浆。该方法还具有利用废料、利于环保和降低成本的优点。
The rejected polyester drinking bottle can be used to prepare low cost recovery unsaturated polyester after alcoholysis and condensation polymerization, which can be used to prepare earlier strengthened polymer modified cement mortar. Its earlier bending strength and earlier adhesion strength with common cement trial block are greatly higher than those of common cement mortar. This method also has the following advantages, such as make use of reject material, good to environment and lower cost.
