红木家具涂料用改性石蜡的制备与性能研究

Preparation and Properties of Modified Paraffin for Padauk Furniture Coatings

针对现有红木家具涂料使用的石蜡原料易于迁移,容易对衣物等造成沾污的缺陷,在保持该涂料"渗蜡"效果的基础上,通过丙烯酸甲酯改性精炼石蜡来提高产品的耐热性并降低其迁移性。通过正交试验优化得到了最佳制备工艺,利用红外吸收光谱、DSC、TGA、磨耗仪等表征分析了产品的性能。结果表明:产物的吸热峰值温度提高了13℃,耐磨性提高了近30%,产品有望用作红木家具的石蜡基涂料。

Regarding the shortcomings （ i. e. easy to be migrated and stain the clothes） of paraffin used in padauk furniture coatings, the paraffin was modified by methacryiate in order to enhance the thermal resistance and depress the migration. The optimum preparation process was gained by orthogonal experiments. The product was characterized by FT -IR, DSC, TGA and abrasion tester. Results showed that the thermal resistance increased by more than 13℃ and the abrasion resistance increased by 30%. The product was potentially applicable in the paraffin based coatings for padauk furniture.
