汽车内饰件VOC散发规律及控制

以门饰板总成为目标进行分解研究,对总成及其子级件的VOC含量进行分析发现不同材料和工艺对总成VOC的权重表现依次是PP类、表皮包覆类零件、表面处理类零件。其中PP作为用量最大的材料,直接关系到整个总成的VOC表现;TPO表皮、针织面料是目前相对环保的表皮类型;在一些非外观的骨架材料方面,本体法ABS相比于乳液法ABS具有一定的优势;相比溶剂胶和热熔胶,水性胶是成本和性能综合优势明显的胶粘剂类型。

VOC Emission Rule and Control of Automobile Interior Parts

The VOC content of the door trim assembly and its sub-parts is analyzed by composing, and it is found that different materials and processes have a big influence on the VOC of the assembly in order of PP, skin-coated parts, and surface treatment parts. Among them, PP is directly related to the VOC performance of the entire assembly as the most used material;TPO skins and knitted fabrics are relatively environmentally friendly skin types;in some non-appearance framework materials, the body method ABS has more advantages than the emulsion method ABS.Compared with solvent adhesives and hot melt adhesives, water-based adhesives has obvious comprehensive advantages in cost and performance.
