一, “ resin ” this type of method 历

plastics is types polymer/macromolecule polymer is main/primary formed separation material, 由 combined formed resin and filler, increase agent, stabilizer, lubricant, color material and other additives 组 formed, in manufacturing and processing process in 呈流体状态, 以方便造 type, in processing formed 时呈现 solid 态形状. plastics main/primary formed separation is combined formed resin. resin most 初由动植 material separation 泌出 脂质而 名, 如松香, and other, combined formed resin （ has 时也直接简称 is “ resin ”） is 指尚未 and various additives mixed combined polymer/macromolecule polymer. resin plastics weight 40%～100%. plastics basic property can main/primary 决定于 resin property 质, additives important function.

二, plastics is what need modified?

谓“ plastics modified ” is through in plastics resin in add types or multiple its it material 质, to its has property can, improvement 一方面 or more property can, from to its suitable scope/range methods. modified plastics material 统称“ modified plastics ”.

plastics chemical industry research development 至今, already combined formed upper types polymer/macromolecule material, its in tool has industrial value 仅百余 types, plastics commonly used resin raw materials 90% above in in large general purpose resin （PE, PP, PVC, PS, ABS）, currently again combined formed large new polymer/macromolecule material difficult degree very large, 既不经济也不现实.

therefore, in-depth research polymer formed, structure and property can 关系, in 此基础 upper for has plastics modified, manufacturing suitable plastics new material, already formed is development plastics industrial has 效途径之一, full modified plastics industry therefore in year inner obtain long development.

plastics modified is through material 理, chemical or 二者兼 tool method make plastics material property can toward 人们 预期 direction 发生变化, or make cost significantly reduce, or make certain property can improvement, or 者赋予 plastics material full new function. modified process can in combined formed resin polymerization process in 发生, chemical modified, copolymer, grafting, crosslinked and other, can in combined formed resin by processing process in 进行, material modified, filling, blending, reinforcement and other.

三, plastics modified methods has which?

1. plastics modified methods large has below/following type type:

1） reinforcement: through add glass fiber, carbon fiber, powder and other fiber or sheet/slice filler to increase material rigid property and strong/high degree 目, power tools in use glass fiber reinforcement nylon and other.

2） toughened: through in plastics in add 入橡胶, thermoplastic property elastomer and other its it material 质 达 to improve/increase its tough property / impact strong/high degree 目, automotive, home appliances and industrial applications in Common toughened polypropylene (PP) and other.

3） blending: will types or multiple full versus polymer material uniform mixed combined formed macro versus 容, micro separation versus mixed combined material, meet/satisfy for material mechanical properties, optical property can, processing properties and other certain requirements methods.

4） alloy: and blending versus 似, separation versus property good, easy formed versus system, and can obtain mono separation method to certain property can, 如PC/ABS alloy, or PS modified PPO and other.

PC/ABS alloy used for automotive 门 手（毛胚 and electroplating parts ）

5） filling: through in plastics in add filler to improvement material mechanical properties or reduce cost 目.

6） its it modified: 如 utilizing conductive property filler reduce plastics electrical retardant rate; add resistant oxidation agent / light stabilizer improvement material weather resistance; add material /染 material 改变材 material color, add inner / outer lubricant make material processing properties to improvement, use nucleating agent semi crystallization property plastics crystallization features improvement its mechanical properties and optical property can and other and other.

remove upper material modified methods outer, also has utilizing chemical reaction for plastics modified , make obtain property can methods, maleic anhydride grafted polyolefin, polyethylene (PE) crosslinked, textile industry in utilizing oxidation material make resin degradation improvement flow property / formed property can and other 不一而足.

industrial upper 经常会 will multiple modified methods use, ratio in plastics reinforcement modified process in is more loss impact strong/high degree meanwhile add 入橡胶 and other toughening agent; or thermoplastic property 硫化胶(TPV) production in meanwhile in material mixed combined and chemical crosslinked and other and other ……

实际 upper, 任何一 types plastics raw materials in 出厂时都 most 起码含 has ratio/proportion stabilizer, anti its in 储存, and processing in degradation, therefore, 严格意义 upper “ non modified plastics ” is in. is, in industrial upper, usually will factory production resin formed is “ non modified plastics ”, or “ pure resin ”.

四, plastics industry chain process/workflow 图

modified plastics process/workflow

随 plastics industrial development, plastics industry inner combined separation generate 一 位于 production combined formed resin large type enterprise and production specific plastics products plastics processing enterprise between versus for industry, this industry production multiple applications and features in pellets material is main/primary product, modified plastics industry.

company from 事 专业 field/area is modified plastics production, will general purpose resin add modifier, masterbatch and functional masterbatch and other additives production used for use electrical appliances, automotive, electronics electrical, office equipment, power tools and other lower industry modified plastics pellets, will separation modified plastics pellets 进一步 processing is as is home appliances, automotive use parts modified plastics products.
