The invention discloses an automobile sign and a processing technology thereof. The automobile sign comprises a shell and a filling body, the middle of the shell is sunken to form a cavity for containing the filling body, the filling body comprises an inner-layer filling body located in the cavity and a surface-layer filling body pasted to the surface of the inner-layer filling body, and the surface-layer filling body comprises, by weight, 90-100 parts of chloroprene rubber; 50 to 60 parts of ethylene propylene diene monomer; 20-25 parts of tung oil modified phenolic resin; 6-9 parts of a compatilizer; 4-6 parts of a gloss enhancer; 5-7 parts of magnesium oxide; 2-3 parts of zinc oxide; 2-3 parts of stearic acid; 2-3 parts of a vulcanizing agent A; 1-1.5 parts of a vulcanizing agent B; 1.5to 2 parts of an accelerant and 50-60 parts of a filler. The gloss enhancer takes emulsified wax and polyethylene wax as main materials, and a wax molecular chain and a rubber matrix are subjected tomolecular bonding during rubber mixing and are migrated and separated out to the surface of the rubber matrix to form a glossy wax film, so that the brightness of a rubber material is improved, the service life of rubber is prolonged, and the ageing resistance is improved.
本发明公开了一种汽车标牌及其加工工艺,汽车标牌包括壳体以及填充体,所述壳体中部凹陷形成放置填充体的型腔,所述填充体包括位于型腔内的里层填充体、粘贴在里层填充体表面的表层填充体,所述表层填充体包括如下重量份的组分:氯丁橡胶90‑100份;三元乙丙橡胶50‑60份;桐油改性酚醛树脂20‑25份;相容剂6‑9份;增光剂4‑6份;氧化镁5‑7份;氧化锌2‑3份;硬脂酸2‑3份;硫化剂A 2‑3份;硫化剂B 1‑1.5份;促进剂1.5‑2份;填料50‑60份。增光剂以乳化蜡、聚乙烯蜡为主料,炼胶时蜡分子链与橡胶基体发生分子键合,并迁移析出至橡胶基体表面,形成一层具有光泽感的蜡膜,使得橡胶材料的亮度提高,且延长橡胶使用寿命,提高耐老化性能。
