一, plastics Color Matching 定义

定义: Color Matching is in 红, 黄, 蓝三原 color types basic color upper,配出令人喜爱, combined color Color Difference requirements, combined 客户希望 to color, 经济并 in processing, use in color color color;

another plastics color also can plastics multiple function,如 improve/increase plastics lightfast property and weather resistance; plastics certain function, conductive property, anti-static property, antimicrobial property can and other 特殊材 material.

二, material and material

features: material is can solvent 于普通 solvent agent color agent,故 need obtain color property can, need use machine add temperature mixed and other methods will material uniform dispersion plastics in.

classification: structure material can separation is has machine material and 无 machine material .

（1）无 machine material

advantages: heat stabilized property good, has non good weather resistance can, light stabilization property excellent 良, price low, dispersion property can excellent 越;例如: titanium powder, carbon and other;

titanium powder series: main/primary has titanium powder, oxidation zinc, zinc 钡白三 types. titanium powder separation 金红石 type and titanium type types structure,金红石 type titanium powder rate high, cover/cap force high, stability, weather resistance good. main/primary used for cover/cap resin rate and increase degree function.

炭黑: is commonly used black material, price 便宜, another also tool has for plastics outer 线保护 anti-aging function and conductive function. 炭黑按 applications separation has color 素炭黑 and 橡胶补 strong/high use 炭黑.

disadvantages: color force versus for 差, versus for density large, add amount relatively large, color 不鲜艳.

main/primary used for: used for increase color concentrated degree according to color need generally various resin can, especially is in engineering plastics has good excellent property can, 例如: PA, PC, PBT, POM, PPO, PPS and other material and non transparent color, color and other resin in;

（2） has machine material

advantages: color force relatively high, color 泽鲜艳, color full, versus for density small, add amount small.

disadvantages: heat resistant property, weather resistance and cover/cap force 方面不如无 machine material, dispersion 效果差, transparent property versus for/regarding material relatively 差,且 price relatively high;

main/primary used for: POM, PE, PP, TPU, TPE and other crystallization material and separation 鲜艳 染 material degree can to color color product product in.

（3）染 material

advantages: 染 material is can used for large more solvent agent and by color plastics has machine combined material, advantages is density small, color force high, transparent degree good.

disadvantages: its generally separation structure small, color easy 发生迁移 crystallization material price relatively machine 贵,部 separation price and has machine material price 接近.

（4）珠 light material

also 叫云母 titanium light material, is types oxidation titanium coating 云母晶 sheet/slice; according to color versus different, can separation is type light material, color type light material, color color type light material type.

三, Color Matching color process

Color Matching color can using/adopting color powder add resin method, color powder mixed combined resin extrusion method and color masterbatch method.

color powder add resin method : color powder and plastics resin mixed combined rear,送入 lower products molding process,工序 short, cost low,但工 as ring 境差, color force 差, color uniform property and quality stability property 差;

color powder mixed combined resin extrusion method : this type of methods for resin and color uniform degree most good, can make material separation dispersion in resin in, color 准确, quality dry 净, easy processing;

color masterbatch method : is color agent and resin, dispersant, other additives made formed concentrated degree color agent material, products molding according to color requirements, add 入一定 amount color masterbatch, make products has requirements color agent amount,达 to color requirements;

color masterbatch can color resin classification,如ABS color masterbatch,PC color masterbatch,PP color masterbatch and other; can color resin processing classification, has injection molding, film, extrusion grade large type masterbatch; color masterbatch due to for material 先进行预处理, has relatively high color force, use amount can reduce quality stability,运输, 贮存, use 方便, ring 境污染 large is reduce;

dispersant through for material lubricating wet, troubleshooting surface gas, will poly 体, poly dispersion formed fine micro, stability and uniform pellets,并 in processing process in again poly, commonly used dispersant is low molecular weight polyethylene wax, for/regarding relatively difficult dispersion has machine material and using/adopting EVA wax or oxidized polyethylene wax, combined formed low molecular weight polyethylene wax and polyethylene (PE) understanding method made low molecular weight polyethylene wax has very large 差别; other additives has coupling agent, antioxidant, light stabilizer, anti-static agent, filler and other,视 requirements and product types add amount,称 is more functional masterbatch, again add light agent, has 利于模塑 products demolding and improve/increase products surface light degree;

color masterbatch property can indicators has Color Difference, degree, degree, yellowing degree, heat stabilized property, oxygen index (LOI), melt flow rate and other,当然颜 material fine degree, property, chemical resistance, property and color masterbatch property can has 关, has indicators in applications in separation important,如 fiber grade masterbatch pressure value DF value fine degree;
