Shanghai Daoqin Plastics Co., Ltd.

         is what need use anti agent

         transparent plastics film, sheet/slice or sheet/plate 材, in wet ring in, wet degree to below/following 时, in its surface 凝结一层 fine micro water 滴, make surface 模糊雾化, retardant light 波 透, utilizing film packaging product 时, 也会因结雾而看不见 inner material, but also generate also easy formed inner material loss bad.

         therefore, is improve/increase product suitable lifespan, need add 入一定 amount anti agent,

         what is plastics anti agent

         anti agent is 一 belt/tape has hydrophilic water surface active property agent , can in plastics surface orientation, hydrophobic water toward inner, hydrophilic water toward outer, from make water easy wet lubricating plastics surface, fine water can speed expand dispersion formed thin water or large water film lower. this can small water light dispersion 射 造 formed 雾化, anti 止凝结 water 滴洒落 to by packaging material upper 面, loss by packaging material.

         anti agent chemical formed main/primary is 脂肪 acid and more alcohol separation ester material . commonly used more alcohol is 甘油, 山梨糖 alcohol and its acid 酐, commonly used acid is C11, C12 saturated and acid or saturated and acid, carbon 原子数 in 24 above acid can use. generally 说, in 链脂肪 acid ester anti 雾效果 good; long 链脂肪 acid 脂持久 anti 雾效果 good. upper anti agent is multiple acid mixed combined ester, many more alcohol acid ester hydrophilic water property, through ring oxygen add formed, can improve/increase hydrophilic water property, increase large anti property and low temperature anti property.

         anti agent classification

         plastics anti agent type type according to anti agent add plastics in methods, can will anti agent separation is inner add type and outer coating type 两 type.

         inner add type anti agent: is in material add to resin in, its features is easy loss 失, can 持久, for/regarding crystallization property relatively high polymer (例如: PET, PS and other) difficult obtain good anti property;

         outer coating type anti agent: solvent has machine solvent agent or water in rear, coating plastics film surface, use 简便, cost low, resistant property 差, easy by or scratch 掉, has in inner add type anti agent 无效 场 combined or requirements property use.

         anti agent property can requirements

         anti agent can can separation is anti property, anti property, low temperature anti property and high temperature anti property types. 一 types anti property very difficult tool types 效果, is according to film for anti 雾效果 requirements, selection types combined use.

         anti agent tool below/following property can:

        1, anti can high, 生效迅 speed, resistant property good;

        2, heat stabilized property good, easy hot separation understanding, but also separation understanding material 不导致 polymer degradation;

        3, and its it additives combined property good, 不妨碍 its it additives function;

        4, effect/influence film transparent property, electrical property can, viscous property, resistant property and other function.

        几 types commonly used anti agent features and application

        1, mono acid ester, white wax material, can as is inner add type anti agent, tool has good anti property and low temperature anti property, suitable for food packaging film, in polyethylene (PE) in generally use amount is 1~1.5份, in polyolefin in is 0.5~1份.

        2, 山梨糖 alcohol mono acid ester, color material, is inner add type anti agent, 生效迅 speed 持久, in polyvinyl chloride (PVC) in use amount is 1~1.7份.

        3, 山梨糖 alcohol mono hard acid ester is inner add type anti agent, it is color solid 体, melting point is 60℃, can 持久, used for use film, can used for as food packaging materials, it in polyvinyl chloride (PVC) in use amount generally is 1.5~1.8份, in poly acid ethylene ester in is 0.7~1份.

        4, poly ring oxygen 乙烷甘油 mono hard acid ester is inner add type anti agent, 生效极 fast, tool has good and low temperature anti property. it is color liquid 体, meanwhile has anti-static can, suitable for food packaging film. in polyvinyl chloride (PVC) in generally use amount is 1~1.5份, in polyolefin in is 0.5~1份.
