Shanghai Daoqin Plastics Co., Ltd.

         plastics material color 泽, meanwhile plastics products appearance material or material can is plastics color agent. color agent color plastics products production amount full plastics products production 消费 80% above.

         due to color agent separation in chemical types type different, chemical structure different, plastics color agent product not only applications, color force, cover/cap force, color property or solid property, weather resistance, chemical resistant product property, property and other main/primary property can in significantly 差异, but also for color plastics products processing molding property, processing process hot oxygen stability property, use process light, oxygen stability property can generate effect/influence.

         especially for light, oxygen stability color plastics products, plastics color agent and antioxidant, light stabilizer combined 不当, can color plastics products color or color, also can add fast color plastics products light, oxygen aging speed degree.

        一 color agent for antioxidant function effect/influence

        铬黄 is transparent machine color agent, can used for polyolefin, polystyrene (PS), acrylic resin and other thermoplastic property plastics, its color force strong/high, cover/cap property good, resistant water and resistant solvent agent property excellent 良.

        但因铬黄 is acid or alkali acid 铅同硫 acid formed 含铅化 combined material, and antioxidant DLTP, DSTP, 1035, 300 and other use, in plastics processing high temperature conditions lower 会发生 chemical reaction, formed black 硫化铅, effect/influence plastics products appearance, large degree low antioxidant anti hot oxygen aging function. therefore, color agent can and antioxidant use.

         in addition, polypropylene (PP) separation in has carbon 原子, easy oxygen 引发而 separation understanding, in processing, and application process in must use antioxidant anti aging 保护. in color polypropylene (PP) in, certain color agent and low separation retardant antioxidant chemical reaction, low antioxidant function. separation color agent for polypropylene (PP) in low separation type antioxidant function effect/influence (table/sheet) can separation is type:

        严 heavy effect/influence: method 炭黑, mono nitrogen 红3B, 喹吖啶 ketone product 红, 酞菁蓝, oxidation iron 黄棕;

         in and other effect/influence: 酞菁绿, method 炭黑, 群青, oxidation 铬绿;

        稍 has effect/influence: 镉黄, (硫化)汞镉红, 金红石 type oxidation titanium.

        珠 light powder in certain resin in and mono antioxidant BHT共 use 时, make white products 变黄而引发 product quality issues.

        二 color agent for light stabilizer function effect/influence

         color agent for color plastics products in light stabilizer function effect/influence main/primary has 两方面 function.

        一 is color agent copper, 锰, and other heavy metal or 杂质, tool has light active property, light property, catalytic add fast plastics material light aging speed degree. has copper and 杂质 酞菁蓝会促 make polypropylene (PP) light aging; oxidation iron can make polypropylene (PP) in 苯并三唑, 二苯甲 ketone, has machine salt light stabilizer can decline 20% above; for/regarding polyethylene (PE), oxidation titanium, 群青, oxidation 铬绿, 钴绿, iron and other color agent use, add light aging.

        二 is certain separation structure color agent can and light stabilizer function, 直接削 low light stabilizer can. acid property color agent can make retardant amine light stabilizer 失效; in polypropylene (PP) in, nitrogen 红, can and retardant amine light stabilizer function, nitrogen shrink combined 红BR, nitrogen shrink combined 黄3G can make retardant amine light stabilizer function separation decline 25% and 50% left right.

         table/sheet 2 is different color agent for has 苯并三唑 type light stabilizer (UV—328) high pressure polyethylene (PE) light stabilization property effect/influence. can 看出, 桔铬黄 obvious improve/increase high pressure polyethylene (PE) light stabilization property, 酞菁绿 and 群青略 has improve/increase or more large effect/influence, 而镉黄则 reduce high pressure polyethylene (PE) light stabilization property.

        F.Steinlin and W.Sear use different color agent (1%), antioxidant 1010(0.1%), light stabilizer 770(0.5%) and polypropylene (PP) 于285℃ lower filament, tensile 4倍, to 80 separation 特/24根 fiber. fiber 经 氙灯 light aging test

        当 strong/high degree decline 50%时, for sample 受辐射 amount comparison. comparison 结果说明, use has machine material 黄, 红, separation color polypropylene (PP) fiber, although add antioxidant and light stabilizer, its stability property low color polypropylene (PP) fiber.

         summary: for light, oxygen stability color plastics products, plastics color agent and antioxidant, light stabilizer combined 不当, can color plastics products color or color, also can add fast color plastics products light, oxygen aging speed degree how to positive use additives, for/regarding plastics products stability property important. therefore in plastics modified process in, for/regarding additives structure and property understanding and 掌握, is non important.
