废弃红砖微粉填料制备环保乳胶漆及其性能研究

摘要

研究了利用废弃红砖生产环保乳胶漆的制备方法,通过正交试验分析了乳液种类、乳液含量、醇酯十二含量、丙二醇含量和增稠剂含量对环保乳胶漆性能的影响.结果表明,废弃红砖微粉与苯丙乳液有较好的相容性,当乳液含量为25％～30％,醇酯十二0.4％～1.2％,丙二醇3.00％～3.75％,增稠剂 1‰～1.5‰时,砖质环保乳胶漆产品低温稳定性良好,可成完全悬浮状态,表干时间小于30min,摆杆阻尼次数可达103次,附着力等级大于5,这为建筑废物资源化提供新的途径.%In this paper, the preparation of environmentally friendly latex paint with red brick waste was investigated. Effects of emulsion type, and the dosages of emulsion, coalescent, propylene glycol and thickener were studied in detail. It was indicated that red brick waste powder had a good compatibility with styrene acrylic emulsion. The environmentally friendly latex paint was completely suspended and had an excellent low temperature stability under the optimum condition, which was the dosages of emulsion, coalescent, propylene glycol and thickener were 25％～30％, 0.4％～1.2％, 3.00％～3.75％ and 1.0‰～1.5‰, respectively. In addition, under the optimum condition, the drying time, damped pendulum rod time and adhesion level were less than 30min, 103and more than 5, respectively. All of the promising results manifested that the environmentally friendly latex paint was a potential resource and provided a new platform for reusing construction waste.
