摘　　要：利用乳液(BA9981)、内墙有光浆、低遮盖率浆组合成新的水性涂料基料。通过改变基料成分的比例,设计成15种配方,利用石墨炉原子吸收光谱法对涂料中的铅、铜、铁元素总含量进行了测定,并测定涂料及涂膜的相关性能。铅、铜、铁总含量的相关系数分别为R12=0.9981,R22=0.9966,R32=0.9957。结果显示:在特定的仪器工作条件和符合要求的线性范围内,所测样品中重金属元素铅、铜、铁的含量、涂料的细度、遮盖力、硬度、附着力等均符合国家标准。A Using emulsion（BA9981）, interior wall light pulp and low covering rate of pulp we combined into a new water-based paint binder. By changing the proportion of the amount of basic material, we designed 15 kinds of formula. Using graphite furnace atomic absorption spectrometry to paint in the lead, copper, iron total content were determined, and coatings and related properties of the coating are measured. A correlation coefficient respectively of the total amount of lead, copper R1^2=0.9981, R2^2=0. 9966, R3^2=0.9957. Results showed that the specific instrument working conditions and meet the requirements of the linear range, heavy metal elements in the test sample of lead, copper, iron content and the fineness degree of the coatings, covering power, hardness, gloss, adhesion, etc all meet the national standards.
