Antistatic plasticizer
PVC is a good electrical insulator. It is easy to accumulate static electricity, and the existence of static electricity often brings trouble or even disaster to many applications. The general method of eliminating static electricity is to add antistatic agents in its formula, and it is an active measure to introduce antistatic group into the plasticizer.
As far as the structure is concerned, the intramolecular of the antistatic plasticizer contains many ether based functional groups. For example, the main component of antistatic plasticizer ArrtistaticplastilizerKA is B two alcohol ether. Antistatic plasticizer Vulkano85 is a kind of thioether sulphur plasticizer. The antistatic plasticizer, and polyethylene glycol dicarboxylic acid esters.
In recent years, some research has been done on antistatic plasticizers in China. With aliphatic polybasic acid with ethoxylated ether esterification, supplemented with surface activity and high temperature resistance properties was prepared, antistatic and excellent plasticizing effect PVC antistatic plasticizer.
The newly developed PVC antistatic plasticizer when usage in 5% ~ 8%, the surface resistance of soft PVC products decreased to 107 ~ 8 ohms, the surface resistance of semi rigid PVC products can reach 108 to 9 ohms, and the PVC products have excellent washing performance.
Antistatic agents are added to the plastic or coated on the surface of molded products to achieve the purpose of reducing the accumulation of electrostatic additives. According to the different methods of use, antistatic agents can be divided into two types: internal additive type and outer coating type. The main type of antistatic agents used in plastic is added antistatic agent. It can also be divided into two major categories, temporary and permanent according to the properties of antistatic agents.
Any object with static charge itself, this charge can be negative charge can also be a positive charge, electrostatic charge accumulation to life or industrial production is affected and even harm, will gather harmful charge / eliminate the wrong guiding production / life inconvenience or harmful chemicals called antistatic agent.
Antistatic agents are generally characterized by surfactants, with both polar and nonpolar groups in the structure. Polar groups commonly used (i.e. hydrophilic): carboxylic acid, sulfonic acid, sulfuric acid, phosphoric acid anion, cation amine salt, quaternary ammonium salt, -OH, and -O- groups, non polar groups commonly used (i.e. lipophilic or hydrophobic): alkyl and alkyl aryl, which formed five basic types of fiber industry commonly used ASA, namely amine derivatives, quaternary ammonium salt, sulfate, phosphate and polyethylene glycol derivatives. ASA when the coating is used, the hydrophobic group is adsorbed on the surface of the material, and the outer layer forms a layer of molecular layer of ASA.

Use of two octyl terephthalate (plasticizer DOTP)
1.DOTP has good electrical and thermal properties. It can be used to replace DOP in the sheath of PVC plastic wire and can also be used in the production of artificial leather membrane. In addition, with excellent compatibility, terephthalic acid ester is two PVC acrylonitrile derivatives plastic plasticizer, plasticizer, plasticizer, polyvinyl butyral nitrile rubber plasticizer, plasticizer for cellulose nitrate. The improvement of the product and plays the role of hardness and deformation, can be used as softener in NBR, chloroprene rubber, EPDM rubber and other products three. Especially for cable material, it has good plasticizing effect and low volatility. It is widely used in various products that require heat resistance and high insulation. It is an ideal plasticizer for producing 70 PVC cable material and other volatile resistant products.
2.DOTP is used for the PVC products in the car, which can solve the fog problem of the glass window. DOTP is also used for high quality lubricants or lubricant additives furniture and interior decoration paint, and precision instruments, nitro varnish additives, paper softener, biaxially oriented polyester amide membrane film, plastic bags and other crafts, plasma storage.
3. because the linear molecular structure of DOTP is similar to DOS and DOA, its cold resistance is also better.
The volume resistivity of 4.DOTP is 10-20 times higher than that of DOP, and its mobility is excellent.
5., because DOTP does not contain o-phthalate two formate, it is not an environmental friendly plasticizer in the range of 16 16 kinds of plasticizers containing o-phthalic acid in the European Union and other countries.
When using the copolymer forming method of bicomponent fiber, the outside of ASA layer is damaged, the internal ASA can penetrate into the material surface; surface of ASA molecular layer of a smooth surface, reduce the friction coefficient of the static electricity generated less likely, but the external ASA wash fastness is not good, consider using the reaction compound and fiber to form a covalent bond with at high temperature.
Application of ASA general in water, alcohol and other organic solvents as solvent or dispersant, then coated hydrophobic groups attached to the surface of the material, moisture absorption of hydrophilic groups arranged outwards in the environment, because the water is of high dielectric constant liquid and forming a conductive layer, and trace electrolyte contained in the fiber in some extent reduce the surface resistance; for fabric ASA is saturated long chain cationic surfactants, because the fiber surface was negatively charged and easy to be adsorbed moisture film, dielectric constant of this material friction gap is obviously improved; if ASA is an ionic compound, itself has the effect of ion conductive .
With the ASA in the polymer distribution is not uniform, when added to a certain number, composite surface will form a layer of hydrophilic membrane and arranged outwards, the internal ASA to supplement to the film surface penetration defect degree of compatibility with polymer; therefore ASA will form the two aspects of the contradiction, compatibility good appearance will make to penetration speed slow down, to replenish the surface of ASA and will make the material loss, premature loss of antistatic property.
There is no plasticizer that meets all conditions. In actual use, most of them are made up of two or more and used to make up for a short time. This needs to expand new efficiency, produce compound plasticizer, obtain the best plasticizing effect and meet the requirement of perfect performance. In particular, the auxiliary plasticizer, although their dosage is less, but the effect is more obvious.
Plasticizer is one of the largest plastics additives in the world. It has been paid more and more attention to its safety with the development and application of plasticizers. Governments have begun to realize the potential threat of plasticizers to human health. High efficiency, special effect, non-toxic, harmless and multiple function are the general trend of the global PVC plastic plasticizer.
