摘要:
以甲基丙烯酸为功能性单体、苯乙烯为硬单体和丙烯酸正丁酯为软单体,通过3种基本丙烯酸酯类单体用乳液聚合的方法合成了一种水性丙烯酸乳液.甲基丙烯酸作为功能单体实现水溶性并增加了附着力.研究了单体配比、引发剂种类及用量、反应温度、搅拌速度、单体滴加时间和保温时间对乳液及涂膜性能的影响.实验结果表明,单体甲基丙烯酸、苯乙烯和丙烯酸正丁酯的质量配比为5∶17∶20,单体混合物的的滴加时间为2~3 h, 引发剂过硫酸铵其用量为单体质量的0.7%,加入方式为与单体同时逐滴加入,乳化剂选用OP10和十二烷基硫酸钠的复合乳化剂,其用量分别为单体质量的2%和1%, 反应温度为75~85 ℃,搅拌速度为200~300 r/min,可以制得到稳定性很好的白色带蓝光的乳液,100 ℃下烘干可得到硬度、附着力和柔韧性都很好的无色透明涂膜
Abstract:
An aqueous acrylic emulsion was synthesized by the method of emulsion polymerization with methacrylate as a functional monomer, styrene as a hard monomer and nbutyl acrylate as a soft monomer. The methacrylic acid as the functional monomer achieved watersoluble and increased the adhesion. The effects of the monomer ratio, kind and amount of initiator agent, reaction temperature, stirring speed , monomer dropping time and the holding time on the emulsion and film properties were discussed. The experimental results show that the mass proportion of methacrylate, styrene and nbutyl acrylate is 5∶17∶20, the dropping time of the monomer mixture is from 2 to 3 h, the use amount of initiator ammonium persulfate is 0.7% of the monomer mass, adding dropwise simultaneously with the monomer, OP10 and sodium lauryl sulfate were selected as the emulsifier content with 2% and 1% of the monomer mass respectively, the reaction temperature is from 75 ℃ to 85 ℃ and the stirring speed is from 200 to 300 r/min, white emulsion with obviously blue light and good stability is obtained; under 100 ℃, colourless and transparent film with good hardness, adhesion and flexibility is obtained.
