用于汽车加油管的低温抗静电粉末涂料及其制备方法
摘要：
本发明公开一种用于汽车加油管的低温抗静电粉末涂料，包括以下质量份数的原料制成：35~75份双组分聚酯、3~7份固化剂、0.2~0.5份催化剂、5~15份导电金属粉末、0.3~0.5份消泡剂、15~20份硫酸钡、5~15份陶瓷土、1~2份流平剂；其中，双组分聚酯包括15~35份聚酯A、20~40份聚酯B；所述聚酯B为丙烯酸单体改性的饱和聚酯树脂，其酸值在30~37mgKOH/g、粘度在3000~6000mPa.s/200℃。本发明还公开制备用于汽车加油管的低温抗静电粉末涂料的方法。本发明具有固化温度低、绿色环保、低电阻，避免加油管与加油枪之间的静电火花产生的技术效果。
摘要（英）：

The invention discloses a low temperature antistatic powder coating for automobile oil filling pipes. The powder coating is prepared from the following raw materials by mass: 35-75 parts of bicomponent polyester, 3-7 parts of a curing agent, 0.2-0.5 part of a catalyst, 5-15 parts of conductive metal powder, 0.3-0.5 part of a defoaming agent, 15-20 parts of barium sulfate, 5-15 parts of ceramic clay, and 1-2 parts of a leveling agent, wherein the bicomponent polyester comprises 15-35 parts of polyester A, and 20-40 parts of polyester B; the polyester B is acrylic monomer modified saturated polyester resin, and has an acid value of 30-37mgKOH/g and viscosity of 3000-6000mPa.s/200DEG C. The invention also discloses a method for preparation of the low temperature antistatic powder coating for automobile oil filling pipes. The low temperature antistatic powder coating provided by the invention has the technical effects of low curing temperature, green and environment protection and low resistance, and avoids generation of electrostatic spark between oil filling pipes and oil guns.
