Formulation Design and Performance of MMA Two-component Marking Paint Based on Mixing Experiment Design
考虑标线涂料配方各组分间的相互作用对标线性能的影响,采用混合实验设计(MED)方法,根据Design-expert v13.0软件给出的响应面分析结果,对MMA双组份标线涂料配方进行优化.通过红外光谱确认了MMA树脂固化后的化学结构,测定了固化剂BPO加入量对标线涂料的不粘胎干燥时间、铅笔硬度和色差(ΔE)的影响,结果表明,室温下BPO加入量1.5%时性能最佳.将配置涂料所用的树脂、颜料和两种填料的用量作为实验变量,以粘度、白度、粘结强度和紫外老化前后的色差作为性能响应指标,通过方差分析选择软件中的匹配模型并确定最佳的涂料配方.结果证实所选模型和实验测量值之间具有一致性,表明混合实验设计法是一种优化标线涂料配方的有效方法.
Considering the influence of the interaction between the components of the paints on the marking performance,the MMA two-component marking paints formulation was optimized by using the mixed experimental design(MED)method,based on the response surface analysis results given by Design-expert v13.0 software.The chemical structures of MMA resins after curing were confirmed by infrared spectra.The effects of BPO amount on no-pick-up time,the pencil hardness and color difference(ΔE)of paints were measured.The results showed that when 1.5%BPO was added,the best performance was obtained.The amounts of MMA resin,pigment and two kinds of fillers were taken as the experimental variables.The viscosity,whiteness,bond strength and color difference before and after UV aging were used as the response performance.The appropriate proposed models in the software were used to determine the optimal paints formulation.The results confirm the consistency between the prediction model and the experimental values,which indicates that the MED method is effective to optimize the formulation of marking paints.
