Alkyl sulfonic acid vinegar plasticizer
The alkyl sulfonic acid vinegar plasticizer is of good solubility and can be used as the main plasticizer. The effect of the alkyl sulfonic acid acetate plasticizer and the main plasticizer of phthalic acid two formic acid is better.
The alkyl sulfonic acid vinegar plasticizer has good mechanical, electrical and weatherability, but the cold resistance is poor.
(1) petroleum sulfonic acid benzyl ester (M-50). A light yellow transparent oily liquid.
(2) Petroleum esters of chlorinated oil. A mixture of alkyl chloride benzyl ester and chlorinated paraffin, light yellow transparent oil.
Any polymer added to the polymer system can increase the plasticity of the polymer system, improve the processability, and give the material flexibility and elongation, all of which can be called plasticizers.
Plasticizer is usually a "solvent like" substance. When added to plastics, resins or elastomers, it can improve their workability and increase plasticity, flexibility, tensile or expansive substances. Adding plasticizer can reduce the melt viscosity, vitrification temperature and elastic modulus of plastic, but will not change the basic chemical properties of plasticized substances.
Plasticizers can change the properties of polymers, which is generally considered to be:
Plasticizer isolates the distance between macromolecules of polymer, and weakens the attraction force between polymer molecules, which weakens the van Edward force between resin molecules.
Nonpolar plasticizers are added to non-polar polymers, which partitions the polar parts of polymer molecules, so that no polar connection occurs, and the dipole dipole interaction between polymers is destroyed.
Plasticizers are combined with a couple of resins instead of chemical forces (covalent bonds).
The basic information of two octyl terephthalate (plasticizer DOTP)
Chinese Name: two octyl terephthalate
Synonyms: two Chinese terephthalate (2- ethylhexyl) ester; dioctyl terephthalate two; terephthalic acid two 1,4- benzene carboxylic acid isooctyl ester; two bis (2- ethylhexyl) ester; terephthalic acid two (2- ethylhexyl) ester; dioctyl terephthalate (DOTP); two double 2= ethylhexyl terephthalate; bis (2- ethylhexyl) terephthalic acid, plasticizer DOTP

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.
Therefore, when mixed with resin and mixed without chemical reaction, it can change some properties of the resin after mixing, and it can be retained in plastic products for a long time, and the substances that change the properties of plastic products can be used as plasticizers. The substances that have these functions are mostly liquid organic compounds or low melting point solids. They have to be polar, compatible with resin, stay in resin for a long time, and have good performance, high efficiency and low price for the resin.
The technology and application of plasticization originated from the original inventions of human beings. In ancient times, water clay ceramic, gelatin in water system sweet snacks, soft leather with oil and gas for asphalt paving materials, cellulose nitrate plus tar roof materials, the various products in the water, oil, tar, which played a plasticizing effect, which is called the various products in the plasticizer. In the course of more than a century, with the development of plastics and rubber industries, more than 20000 plasticizers have been recorded in the literature in 1943. More than 150 kinds of industrial production can be produced.
The total output of world plasticizer in 1975 reached 320 thousand tons. By 2000, the total production capacity of plasticizers in the world has reached 6 million 400 thousand tons, and there are more than 500 industrial varieties. The total sales of plasticizers accounted for 60% of the plastic additives.
Since then, with the rapid development of the plastics industry, there have been better polyester plasticizers, epoxy plasticizers, low temperature plasticizers and high energy plasticizers for rocket propellants, explosives and munitions.
Now, one of the important fine chemical product variety, mass production of plasticizer industry has been in the form of the adjacent benzene two formic acid ester based, its varieties and production are listed in the first plastic additives.
Many plasticizers can play a great role in changing the properties of the polymers, the processing of the polymers and the properties of the products.
Reduce the glass temperature of the polymer. The structure of the polymer is changed to soften the plasticized material. The elongation of the polymer is increased and the tensile strength is reduced. The toughness of the polymer is increased and the impact resistance is improved. Improve low temperature performance. The viscosity of the polymer is reduced and the processability of the polymer and its mixture is improved.
Change the rheological properties of polymers, especially products with high polymer content in products. It can reduce melting temperature, reduce gel temperature, shorten mixing time and reduce extrusion pressure. It is easy for melt body to operate on various kinds of equipment, reduce the temperature of adhesive and improve the smoothness of brushing. Using plasticizers in products to improve the interaction with water: hydrophilic plasticizers increase the absorbability of products to water, increase the curing speed of water products, reduce or increase adhesion and cause expansion. Hydrophobic plasticizers reduce the sensitivity of products to water.
It is helpful to the dispersity of liquid and solid additives. It is more effective for the filler, dye and other liquid additives that are soluble in plasticizers. Increase or weaken the conductivity or insulation of a product. Improve the sensitivity of the products to combustion, increase the flame retardancy, and inhibit the amount of tobacco. Plasticizing biodegradability. The degradation rate of products can be increased by adding degradable plasticizers into biodegradable materials.
