Plasticizer for PVC coating
In polyvinyl chloride coatings, the products with basic structure are not ideal and have inherent rigidity or brittleness, which is what we don't want. In order to soften the polymer, it becomes flexible, flexible, and must be added to other additives. This additive is the plasticizer of PVC coating.
In addition to the flexibility and flexibilities of the polymer, the plasticizer of PVC can also reduce the glass temperature of the polymer. Polyvinyl chloride coating plasticizer is usually liquid and many varieties.
1. dibutyl phthalate. This product is often abbreviated to DBP. Colorless transparent liquid, microstrip aromatic smell. As a plasticizer in the paint, but also enhance the scraping of the dope.
2. o-phthalic acid two octyl ester. This product is often abbreviated to DOP. In the role of imitation porcelain paint, and dibutyl phthalate, interchangeable.
3. - phthalic - two - formic acid two methyl ester. This product is often abbreviated as DMP, colorless and transparent oil like liquid, with aromatic smell. O-methyl benzene two carboxylic acid two methyl ester is both solvent and plasticizer, and has high speed increasing ability. It has good solubility with various cellulose resins and vinyl resins, and has good film forming property, adhesion and waterproofing property. This product can also be used as anti mosquito oil solvent, which has certain toxicity, irritation to the eye mucosa. 4. phthalic acid and two formic acid two ethyl ester. This product is often abbreviated as DEP, colorless and transparent oil like liquid, with a slight fragrance. As a plasticizer, it is often used with two methyl phthalate two formate. In the role of dibutyl phthalate is better than imitation porcelain paint.
5. polyol benzoate plasticizer. This product is often abbreviated to DEDB and is a plasticizer named 9588. This product is dibutyl phthalate two formic acid two ester substitution. This product is light yellow transparent oily liquid, insoluble in water and the relative density of 1.072~1.076, according to the index is divided into first and two products, the ester content and chroma respectively in more than 99.5%, aged 99% and 120, ranging from 140.
Performance: This product with PVC and vinyl acetate copolymer, polyvinyl acetate with good compatibility, compatibility with PVC, PMMA, polyvinyl butyral, nitrocellulose, cellulose acetate and ethyl cellulose. The performance of many aspects is superior to DOP, and it is the 8611 upgrading and replacement product in China.
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.
Application and application scope and method: This product is the main plasticizer of PVC and vinyl acetate. It has low processing temperature and short plasticizing time. It can be used for PVC asbestos flooring and extrusion plastic, unfilled calendering film, artificial leather and all kinds of shoes.
This product has the advantages of high efficiency, good solubility, large safety factor and good flexibility. If it matches the certified product DOP/DBP, it will increase the effect of speed increase and reduce the cost effectively.
Plasticizer (plasticizer, softener) is used to increase the flexibility of a paint additive. Plasticizers are usually nonvolatile organic compounds with low molecular weight, but some polymeric resins can also be used as plasticizers. Plasticizing resins are also called plasticizers, such as alkyd resins used as plasticizers for chlorinated rubber and nitric acid fiber coatings. Both plasticizer and plasticizer must have better miscibility in the plasticized resin.
The plasticizing effect of the plasticizer is achieved by reducing the glass temperature of the base resin. The vitrification temperature is the temperature of the resin from a hard brittle solid state (glass state) to a rubber like high elastic state (high elastic state). Plasticizers can be divided into two types: Main plasticizers (solvent plasticizers) and plasticizers (non solvent plasticizers).
Principal plasticizers: some of their groups interact with some of the groups in the resin, so the main plasticizer and the resin can be mixed with each other. Because plasticizer molecules are smaller, they enter the molecular structure of resin polymers and reduce the rigidity of resins, but their mechanical properties will suffer some losses if they join.
Plasticizers: there is no dissolving effect on the base resin. They can only be mixed with the base resin when they are not too much. Plasticizers only have physical effects (lubrication) on the base resin, so the effect of the plasticizer on the mechanical strength of the coating is not as large as that of the main plasticizer, but the plasticizer is easy to migrate from the coating or be lost, and the flexibility of the coating is poor.
In general, the addition of plasticizers will increase the extensibility of the coating and reduce the tensile strength of the coating. Within a certain amount of plasticizer, the permeability of the coating will remain unchanged. However, the strength and adhesion of the coating first increase with the addition of plasticizer, but it will decrease after reaching a peak value. Plasticizer not only affects the mechanical properties of coatings, but also affects other properties of coatings. Therefore, the most appropriate amount of additives should be comprehensively balanced according to various factors to determine.
