Auxiliary plasticizer
Or a plasticizer, plasticizer, plasticizer, is an increase of soft material or additive material liquefaction. Its added objects include plastic, concrete, dry wall materials, cement and gypsum, and so on. The same plasticizer is often used on different objects, but the effects are often different. There are more than 100 kinds of plasticizers, but the most common use is a group of compounds called phthalic acid esters.
Plasticizers are classified a lot, and the methods of classification are different. The commonly used types are divided into three types according to the compatibility, chemical structure and function of plasticizers.
The main plasticizers and auxiliary plasticizers are classified according to the compatibility classification. The plasticizer, which is highly compatible with the resin (mainly PVC), is still compatible with the proportion of plasticizers and plasticizers to 1:1). These plasticizers not only enter the amorphous region of the resin chain, but also enter part of the crystalline region of the resin molecular chain, which can be used to gel with the resin, but do not exudate to form droplets or liquid membranes, nor will frost spray on the surface. This plasticizer can be used alone.
If the plasticizer and resin poor compatibility of plasticizer molecules can enter the resin molecular amorphous region and can not enter into the crystallization zone and resin gelation ability is poor, the resin plasticizer plasticizer, plasticizer can seep from products or spray cream, this kind of helper increase plasticizer. It can't be used alone, only with main plasticizers. The price of auxiliary plasticizer is cheap, which can reduce the cost of products, and auxiliary plasticizer is also called incremental agent.
Classified according to function. Some plasticizers have extensive adaptability, but they have no special functions. This kind is called universal plasticizer. Such as phthalic acid esters of two formic acid. There are also some special functions: cold resistant plasticizers, flame retardants, nontoxic plasticizers, permanent plasticizers, high energy plasticizers, heat-resistant plasticizers, mouldproof plasticizers, etc.
Through the above analysis, we can see that under the current level of technology, it is impossible to replace plasticizer with one substance completely. Because DOP and DBP occupy 80% market share at present, it will take a long time to replace them completely.
The cost of PVC is increasing, so it is very important to choose a suitable plasticizer to replace the traditional plasticizer.
Auxiliary plasticizers play an important role in this. Because the price of auxiliary plasticizer is much cheaper than that of main plasticizer, and its plasticizing effect is almost the same as that of main plasticizer, it is the best main plasticizer substitute for enterprises to reduce costs and improve market competitiveness.
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.
Packing method:
200KG/ net galvanized steel drum (a small pallet loaded 16 tons), 1000KG/IB (a small barrel loaded 18 tons or 23 tons of ISOTANK).
PVC resin is one of the largest synthetic resins in our country. In the future, more and better plasticizers with good quality and low price are needed. In the future, we should focus on solving the problems of development and production of supporting plasticizers. For existing varieties, we should improve quality wells and strive to reduce costs. At the same time, we should strengthen the development and utilization of new plasticizers, and use plasticizers rationally.
Dicyclohexyl phthalate two formic acid (DCHP) is a kind of moisture-proof plasticizer, can make the plastic surface shrinkage to dense, moisture and prevent plasticizer volatilization effect, the production of domestic small scale, should improve the technology and expand production to meet domestic demand; mildew resistance plasticizer benzoate (benzoic acid, diethylene glycol, benzoic acid, nonyl ester C two drunk) two benzoic acid diethylene glycol ester and two benzoic acid two propylene glycol and polyvinyl chloride, poly ethyl acetate and many synthetic resin has good compatibility, oil resistance, contamination resistance, extraction and processing, volatility and mobility. Can improve the workability, reduce the melt temperature and shorten the processing time, is an ideal plasticizer used as high filling floor material rolling and extrusion, but the fungus resistance difference.
If benzoate is mixed with two benzoate in a specific proportion, it has excellent mold resistance in addition to the retention of the above properties. The higher the amount of hemicester (that is, hydroxyl value) in two benzoate, the better the resistance to mould. High molecular weight plasticizer is characterized by good durability and long lasting plasticization. Therefore, developing amorphous polymer with low glass transition temperature Tg and good compatibility with plasticized polymers is the future direction.
Our country is rich in resources of chlorinated paraffin wax, mature production technology, the development of soft high chlorine content of chlorinated paraffin; China's high carbon alcohol sufficient raw materials should be developed adjacent benzoic acid plasticized high efficiency, heat resistance, weather resistance, low volatile, health and transparency than DOP two octyl / decyl ester (810 ester) and other varieties; China's ethylene glycol production has more than 600 thousand t/a, two glycol polyol by-product of diethylene glycol ester of benzoic acid should be developed in low price, low volatility and low toxicity and cold resistant varieties; recycling of waste polymer using two formic acid two of isooctyl polyester silk (DOTP), the volatile, electric performance is better than DOP, low temperature resistance, anti extraction, heat resistance, is an ideal plasticizer.
