High energy plasticizer is a kind of liquid plasticizer that can increase the heat of explosive material. The commonly used nitrate ester plasticizer three high-energy trimethylol ethane three nitrate ester (TMETN), three hydroxy methyl methane three nitrate (TMMTN), two triethylene glycol two nitric acid ester, diethylene glycol dinitrate two (DEGDN), ethylene glycol dinitrate (EGDN) two, 1, 2. 4- butyl three alcohol three nitrate ester (BTTN), two glycerol four nitrate ester and so on.
Nitrate ester plasticizer and energy structure similar to the plasticizing effect of nitroglycerin. The chemical properties of TMETN are stable, insoluble in water and low volatilization.
Three trimethylol ethane three nitrate called methyl isobutyl alcohol three three nitric acid, phenol, micro thick yellow transparent oily liquid, the melting point of a 3}., a L7} (stable}) [} stable), boiling point 18Z C starts to break down.

The heat of formation 2629.23k]Ikg[constant pressure). The heat of combustion of 14}}2.8kJ}s} (constant pressure), "314U1}1'}K, the outbreak of the explosion heat of S} (223}: 72}), a J1, test d[lrnir, no color, red than nitroglycerin was approximately 10 times lower" by "= ethylene glycol and nitric sulfuric acid was prepared. Used as a propellant energetic plasticizer.
Plasticizers are mainly used in PVC resin, and the amount of the plasticizer is more than 98% of the amount of the plasticizer. The addition of plasticizer can reduce the interaction force between PVC chains, reduce the vitrification temperature and flow temperature of PVC plastic and the melting point of microcrystals. Plasticizer can improve the plasticity of the resin and make the product soft and low temperature resistant.
The influence of plasticizer on mechanical strength is not obvious under 10 parts. When adding 5 plasticizers, the mechanical strength is the highest, which is the so-called anti plasticizing phenomenon. It is generally believed that the anti plasticizing phenomenon is the effect of increasing the activity of the large molecular chain and making the molecules order to produce microcrystals after adding a small amount of plasticizers.
The impact strength of hard products with a small amount of plasticizer is smaller than that without adding time, but when the dosage is increased to a certain dose, the impact strength increases with the increase of dosage, which meets the universal law.
Two octyl terephthalate (plasticizer DOTP) raw materials are generally synthesized from the process route of terephthalic acid or two methyl terephthalate as raw material.

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.
In addition, the heat resistance and corrosion resistance of the products decreased with the increase of plasticizers, and the heat resistance of Martin decreased by 2~3 for each addition of plasticizer. Therefore, the general hard products do not add plasticizers or less plasticizers. Sometimes a few plasticizers are added in order to improve the flow of processing. And soft products need to add a lot of plasticizers, the greater the dosage of plasticizing, the softer the products.
The total amount of plasticizers should be different according to the requirements for the softness of the products, the use, the process and the use environment. The PVC film is produced by the general calendering process. The total amount of plasticizer is about 50. The blow molding film is slightly lower, usually in 45~50 parts.
A variety of plasticizers, according to their compatibility with the polymer can be divided into two types of plasticizers and auxiliary plasticizers. The main plasticizer with two formic acid ester and phosphoric acid esters, auxiliary plasticizer with aliphatic dicarboxylic acid ester epoxy etc.. According to the structure classification of plasticizer can be divided into: two formic acid esters, aliphatic dicarboxylic acid esters, epoxide, polyester etc..
O-phenyl two carboxylic acid two (2- ethyl hexyl) ester (DOP) has high plasticizing efficiency, good volatility, migration resistance, water resistance, weather resistance and other comprehensive properties. The production of soft PVC calendered films, mainly plasticizer in DOP and adipic acid two (2- ethylhexyl) ester (DOA) for cold resistant plasticizer.
The epoxy fatty acid ester plasticizer has good thermal stability and cold resistance. The commonly used varieties are epoxy stearic acid 2- ethyl hexyl ester, epoxy soybean oleic acid 2- ethyl hexyl ester and so on.
The high barrier polyvinylidene chloroethylene (PVDC) film for food packaging should be added with a proper amount of 8~10phr nontoxic plasticizer. The main products are acetyl tributyl citrate and acetyl citric acid three (2- ethylhexyl) ester, decanedioic acid two (2- ethylhexyl) ester (DOS) etc.. These plasticizers are also nontoxic plasticizers commonly used in PVC.
