Phthalate two formate (PAEs) plasticizer
Phthalic acid esters (PAEs) has two kinds of plasticizers from industrial production, for its excellent performance has been widely applied in the fields of chemical and polymer materials, especially in our country, in recent years, with the rapid development of polymer material industry, the demand and the continued expansion of the scale, but with the improvement of science and technology. Along with the people to the living requirements of environmental protection, phthalic acid esters (PAEs) of two kinds of plasticizers negative effect gradually emerged, the harm is more and more attention and concern.
The application of phthalate two formate (PAEs) plasticizer. Phthalic acid esters (two PAEs) is a kind of important organic chemical products, currently in the industry is mainly used for PVC and other plastic material of plasticizer and softener, also widely added to daily polymer rubber products, such as for children's toys, food packaging materials, medical blood bag and disposable infusion tube etc. medical equipment, cleaning agents, lubricants, cosmetics and other personal care products, decoration materials, wallpaper and other household and car floor. So it has a very close relationship with people's daily life.
Phthalic acid esters are used as plasticizers. Plasticizers are the largest amount of additives in plastics, the adjacent benzene two formic acid ester is the most widely used as a plasticizer, the plasticizer all accounted for about 70% of consumption, only China's annual consumption of nearly one million tons, mainly used in polyvinyl chloride resin in rubber and plastic materials.
Phthalate esters, used as plasticizers, generally refer to esters of phthalic acid and 4~15 carbon alcohols, all of which are derived from petroleum. Among them, two octyl (DOP or DEHP) of phthalic acid (DOP) is the most important variety. It is added to the polymer that needs to be plasticized, which can increase the plasticity of the polymer.
Usually, they do not react with polymers. The interaction with polymers is mainly due to swelling at elevated temperatures, forming a solid solution with polymers. The main effect of plasticizer is weakened between polymer molecules price for health, namely Fan Dehua force, thereby increasing the polymer chain mobility, reduces the crystallinity of the polymer chains, which increased the plastic polymer, the polymer showed hardness, modulus, softening temperature and brittleness temperature decreased, and elongation and improve the flexibility and flexibility.
Phthalic two formic acid esters are used as cosmetic plasticizers. O-phenyl two formic acid is used in makeup products, which can make nail polish reduce the brittleness of nails, make hair gel form flexible film on the surface of the hair, avoid stiff hair and make skin products increase the skin's sense of compliance. It can also serve as a solvent for some products and an anti volatile agent for perfume.
Two octyl terephthalate (plasticizer DOTP) raw materials are generally synthesized from the process route of terephthalic acid or two methyl terephthalate as raw material.
Safety data for export goods of two octyl terephthalate (plasticizer DOTP)
CAS No.:6422-86-2
State of the goods: export by general goods.
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 recent years, China's plastics industry has seen an obvious trend of development. The number of scale businesses has increased rapidly, and the industrial structure has gradually adjusted to the scale and intensive direction, with an annual growth of 20%. The research and development of additives is tightly connected and the level of development of polymer materials industry together, in the global plastic additives market in plasticizer accounted for 60% of China's AIDS consumption accounted for almost the world's total consumption of 1/4, and 7% of the annual growth rate in 2010, the world plastics demand will reach 2 million tons.
The medical equipment, which is made of plastic materials containing o-phthalate two, is used for human body, such as disposable infusion sets, medical gloves, plasma bags, hemodialysis pipelines, etc., so that o-benzoate two esters migrate easily from plastic to human body. DEHP was found in the human body, especially in the lungs, when the blood stored in the PVC blood bag, plasticized by DEHP, was found.
The average daily exposure of DEHP through medical facilities is 3 orders of magnitude higher than that of the population. The maximum intake of DEHP is 4mg/kg through blood transfusion and dialysis. At present, the PVC film containing plasticizer DEHA is widely used as an external packaging material for meat, cooked food, oil and food. During the use of DEHA, DEHA will migrate from the food packaging film gradually, and it will eventually migrate to the human body with food. Other plastic containers can also be packaged in food and water into the human body.
Wang Chengyun and other researchers studied the migration behavior of plasticizer DEHA in PVC food packaging film in simulated oil. It was found that the rate constant of migration increased with the increase of soaking temperature and the initial concentration of DEHA in PVC film.
Zhu Yong based Fick diffusion law, using the programming of plastic food packaging in the migration of plasticizer was studied, the results show that the plasticizer migration velocity and contact area, transfer temperature, transfer time and increasing initial concentration of plasticizer was positively correlated with food related solvent.
The soil is the storage and transfer station of the PAEs in the environment. In recent years, many studies have been made on the bioavailability and degradation of PAEs in soil.
It should be pointed out that it has been continuously detected in various environmental media, air, water, soil and dust since it was applied to DEHP. It can be thought that DEHP exists in the environment widely. People are exposed to it through water and food. It is predicted that the potential threat to human health is becoming more and more obvious.
