Plasticizers for biodegradable plastics
The mechanical properties of PLA can be greatly improved by the use of plasticizers in the film and other soft packaging PLA (polylactic acid). The flexibility of the conventional hard PLA is improved by the plasticizer for biodegradable plastics, and its extensibility can be increased from 5% to 320%.
Biodegradable plastics can be biodegradable with plasticizers, and their amount in the products is 10% to 20% of the additives. The modifier is based on the block copolymers formed between PLA and polyethylene glycol. The modified PLA can disappear in the mixture for 20 days to 25 days. The auxiliaries have been industrialized in scale. Promote the healthy development of plasticizers in China.
The new plasticizer is nontoxic, contains no estrogenic and anti androgenic substances, without carcinogens, and does not cause peroxisome proliferation. For children toy manufacturers who are looking for other plasticizers to produce products that can be put in their mouths, nontoxic plasticizer is the least risky option, and a simple plasticizer substitute.
Nontoxic plasticizers meet the highest standards required by laws and regulations, and their non-toxic properties allow many toy manufacturers to feel relieved. The plasticizer does not need to be reconfigured to reduce the risk of expensive product recalls and customer complaints caused by errors in the two configuration. Because of its low initial viscosity and excellent viscosity stability and processability, the plasticizer can meet the requirements of high speed mold production efficiency and cycle period, and ensure the same surface thickness.
The main varieties of epoxy plasticizers are epoxidized soybean oil, epoxy acetyl linolenic acid methyl ester, butyl furfuryl oleate, epoxy silkworm pupa oleic acid butyl ester, epoxy soybean octyl oleate, 9, 10- octyl epoxy stearate and so on.
In PVC products, it is mainly characterized by both plasticity and stability. Epoxy plasticizer (epoxidized oil) is made of natural oils in organic peroxide acid epoxidation and prepared a kind of excellent plasticizer, minimal toxicity, and the main plasticizer DOP and DBP, its outstanding advantage is non-toxic, heat and light stability, allowed for packaging the material of food and medicine in many countries.
The discriminant of a plasticizer is available, on the other hand, the key is not the animal toxicity results, but through in-depth investigation of dosage and toxicity, exposure and hazard, material migration amount and speed and exposure, and then processed for risk controlling measures, the the harm to the public environment to the lowest level through scientific analysis and means. It is hasty and unscientific to take restrictive measures solely on the basis of the results of hazard identification. International management of chemicals, including plasticizers, will continue to be more and more strict and more scientific.
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).
We will increase the strength of research and development and develop new varieties of plasticizers. The world needs for environmental protection plasticizer development lags behind the production and life, with the progress of science and technology, some traditional materials may be eliminated, new environmental protection research and development advantages of harmless, cheap, good effect of additive plasticizer as substitute materials, is a key part of development of the plastics industry.
Plasticizers are indispensable in providing high quality plastics for human beings. But the variety structure constantly changes, the development of new technologies in accelerating the pace of new varieties of more advanced detection means emerge in an endless stream, and the evaluation method is more reasonable, the plasticizer is in such a "development -- Application of toxicology tests - risk assessment - open the" cycle of progress. Therefore, the correct use of plasticizer is the key to the healthy development of the industry.
To do this, the plasticizer enterprises should work hard on the structure adjustment. Foreign countries are energetically promoting nontoxic or environmentally friendly and biodegradable plasticizers. The so-called innocuity and environmental protection are also relative.
For example, DIHCN (cyclohexane two carboxylic acid two ISO nonyl ester), D-810 plasticizer, EBN BET (isooctanoic acid and benzoic acid polyol ester ester) plasticizer, polyester resin plasticizer such as adipic acid and polyol condensed.
At present, the production of environmental protection non-toxic plasticizer is facing two difficult problems. First, there are many by-products, but the yield is not high. The two is low yield, high cost and good products, such as citric esters, because the cost of catalyst is high, which makes the cost of plasticizer quite high.
Due to accelerate the elimination of toxic plasticizers and promote the development of new non-toxic plasticizer has become an inevitable trend, make great efforts to study new catalytic and separation technology to domestic production enterprises as soon as possible, the price will be higher, more security, a new generation of environmentally friendly plasticizer products to the market.
