新型丙烯酸酯抑尘剂的合成及应用性能

Synthesis of an acrylate copolymer emulsion and its use as a water-soluble dust inhibitor

以丙烯酸丁酯(BA)、甲基丙烯酸甲酯(MMA)为主要单体,采用传统的乳液聚合方法合成了稳定的聚丙烯酸酯水溶性抑尘剂乳液,考察了单体配比、引发剂和乳化剂用量对乳液性能的影响。此外,还采用黏度、IR、TG、SEM等方法对乳液进行了表征,研究了其作为固沙抑尘剂时的固沙抑尘效果。结果表明MMA质量含量25%、引发剂占单体质量0.8%、乳化剂质量含量3%时,所得产品作为固沙抑尘剂使用效果好,热稳定性和黏度等满足室外抑尘的需要。

A water-soluble dust inhibitor emulsion was prepared from acrylate monomers by means of conventional polymerization.The influence of various factors such as the composition of the acrylate monomers,the amount of initiator and amount of emulsifier on the performance of the emulsion were investigated.The dust inhibitor was also characterized by viscosity measurements,FTIR,TG and SEM analysis.Its ability to reduce the water erosion of sand and inhibit dust formation was studied in detail.The results showed that a sample synthesizd with 25% MMA,0.8% initiator and 3% emulsifier has good dust inhibiting performance and has suitable viscosity and thermo-stability for practical applications.
