Shanghai Daoqin Plastics Co., Ltd.

         usually production plastics products raw materials is using/adopting pure resin, 如PE, PP, ABS and other processing molding. 随 科技 development, for plastics products material property can more high requirements, pure resin force from 心, development a large amount of new product types resin 也不现实. therefore, through in pure resin in add its it material non metal, metal or has machine material, can improves plastics resin type property can, to need technology indicators or improve/increase property ratio, this 就诞生 一 new industry: plastics filling modified. plastics filling modified industry and non metal 矿, powder processing, processing, processing, ultra- fine powder and other industry combined 起, promote plastics processing industry development. 进入二十一世纪以, 围绕现代 plastics processing industry, less types plastics resin is 主, through add various additives, modifier and filling agent, in 层出不穷 plastics molding processing machine combined lower, plastics products industry already 经渗透 to 农业, industrial, national defense, construction, day use, medical, aviation aerospace and other 社会生 active field/area, 几乎无 不包.

        1, filling agent 定义

        ASTM(USA material experiment/testing 学会) filling agent is “ is strong/high degree and various property 质, or is reduce cost in plastics in add relatively is inert property material 质. ” therefore, plastics filler selection non metal material. 他们泛指由 质 function formed, generally is crystallization 态 天然 non metal combined material or mono 质, tool has uniform versus for solid chemical formed and 确定 晶体 structure; in material chemical conditions lower maintain stability, is formed and basic mono 元. generally is machine material, has 时也包括矿 material material 如煤. 顾名思义, plastics use non metal material filler usually can is is large in in by 人工开采, processing utilizing tool has upper 述定义 property 质 并 by add in plastics in non metal material material, usually by made formed powder 体.

        2, filling agent basic property 质

         in plastics processing and use process in maintain chemical property and material 理形态 stability;

         improvement resin certain property can: high rigidity, improve/increase heat resistant property, improve/increase electrical insulation property;

         improvement weather resistance, increase dimensional stability;

         color force, thermally conductive property, conductive property, flame retardant property;

         price low 廉.

        3, filling agent basic requirements

         chemical property stability, versus for pure degree high, content low;

         color amount is white or shallow color, iron and other easy add hot 变黄 杂质;

        不 for plastics products property can indicators generate heavy loss 害;

        容 easy dispersion and mixed combined, degree 适当;

        吸油 value versus for relatively low, for processing property large effect/influence;

         has combined 适 晶 type structure;

         has relatively low hardness;

         and resin versus ratio has versus for price.

        4, filling agent classification

         according to its usually separation is material property, material property filler and industrial property filling agent. rear can separation is combined molding and waste type.

         according to its separation is powder 末状, 球状, sheet/slice 状, 柱状, and fiber filling agent.

         according to its can separation is increase amount type, strong/high type and function type filling agent.

         according to its chemical formed separation is machine filling agent and has machine filling agent.

         will plastics in application relatively more filling agent chemical formed 份进行 classification lower:

         oxidation material: oxidation silicon, silicon 藻土, oxidation aluminum, oxidation titanium, oxidation iron, oxidation zinc, oxidation 镁, oxidation 二锑, high-speed rail acid 钡, high-speed rail acid 锶, oxidation 铍, oxidation aluminum fiber.

         hydrogen oxidation material: hydrogen oxidation aluminum, hydrogen oxidation 镁, salt property carbon acid 镁.

         carbon acid salt: carbon acid carbon acid 镁, 白云石, alkali carbon acid nano aluminum.

        (亚)硫 acid salt: acid 钡, acid 钙, acid 铵, acid 钙.

         silicon acid salt: slip powder, viscous 土, 云母, 石棉, silicon acid 钙, 蒙脱土, lubricating 土, glass beads, glass fiber (GF).

         carbon 素: 炭黑, 石墨, carbon in 空球, carbon fiber.

         its it: acid zinc, acid 钙, acid nano, acid 钡, titanium acid 钾.

         has machine material: powder, powder, 稻草, 麦杆, housing/shell, powder, 布, 纸, 纸浆, fiber, combined formed fiber and other.

        5, 无 machine filling agent for products property can effect/influence 规律:

         specific gravity filler add amount increase increase large.

         surface hardness filler add amount increase increase large.

         rigid property filler add amount increase increase large.

         resistant strong/high degree filler add amount increase decline.

         fracture elongation filler add amount increase decline.

         surface gloss degree filler add amount increase decline.

         impact strong/high degree filler add amount increase generally is decline;如 filler outer type is 针状, fiber 状, generally is reinforcement.

         resistant temperature property filler add amount increase increase large.

        6, has machine filling agent for products property can effect/influence 规律:

         usually has machine type filling agent add for plastics material mechanical properties effect/influence very large, also has to 普遍规律(has for chemical property can has effect/influence), large has lower 几点共 property:

         products specific gravity filler add amount increase decrease small.

         products surface gloss degree filler add amount increase decline.

         products impact strong/high degree filler add amount increase generally is upper rise; especially powder material outer type is 针状, fiber 状时, generally is reinforcement.

        7, 实际 application requirements filling agent features:

        粒径 and distribution.

        晶 type structure.

        吸油 property.

         dispersion property.

         viscosity features.

         rigid property and hardness.

         electrical properties.

        1) products chemical stability property high, heat resistant property good, in processing temperature degree separation understanding, effect/influence plastics resin has material mechanical properties. add rear products bending, tensile generate phenomenon need small.

        2) products and its it processing additives mixed combined rear 不发生 chemical reaction.

        3) products in plastics resin in dispersion mixed combined property good, effect/influence processing properties, for equipment abrasion loss small.

        4) products amount and absorption plastics resin amount small.

        5) products promote resin accelerated separation understanding 杂质.

        6) products solvent water, 油脂, solvent agent, 不吸潮, crystallization water (flame retardant remove outer), resistant acid resistant alkali.

        7) products filler powder appearance color uniform, coarse fine 一致.

        8) products and 源丰富, stability, different amount filler between quality need small.
