Abstract
The invention relates to a tackifying master batch production process and belongs to the field of organic chemistry. The process comprises the following steps: extruding carrier resin by using a twin-screw extruder; injecting polyisobutene in a melting section of the twin-screw extruder by using a high precision metering pump; and after uniform mixing, extruding and granulating the mixture to produce the tackifying master batch. The production process provided by the invention is simple in preparation process and convenient to implement; the production process is low in energy consumption, and meets the policy of energy conservation and emission reduction of China; the preparation steps are reduced, so that the reaction is conveniently carried; the prepared product is high in content of effective components, excellent in performance, less in dosage, low in cost, easy to produce, high in viscosity and uniform in bonding layer, and the membrane strength, transparency and the like can be enhanced.
Description
Technical field
The present invention relates to a kind of thickening masterbatch production technique, belong to organic chemistry (modifying plastics) field.
Background technology
Along with the raising day by day of people's living standard, the quality of the many lives of people also becomes more and more fastidious, the demand of esp milk and meat, has risen to environmental protection, safe, pollution-free, nuisanceless level from original requirement of having enough to eat and wear.High-quality is nuisanceless, the supply of noresidue milk and beef or mutton is imperative.In winter, nutrition is very abundant after the fermentation has been completed for the herbage of storage, but the green grass or young crops storage herbage preserved in sealed states is once ingress of air, and 24 hours will produce a large amount of flavacin, cause the secondary pollution of meat, milk preparation.In European and American developed countries, in order to stop the generation of flavacin in greenfeed, the herbage of livestock-raising has not re-used huge pond storage forage grass, but uses the film with self-adhesion function, greenfeed is packaged into heavily about 300-500 kilogram parcel, opens at any time and finish using at any time.This film is referred to as blue or green storage herbage film, and the production of this film, be unable to do without thickening masterbatch.
Certainly, this thickening masterbatch is also widely used in such as the industry of other self-adhesive foils and is wound around film, protective membrane, preservative film etc.But the preparation of current thickening masterbatch, active constituent content is low, and technique is loaded down with trivial details, consumes energy huge, does not substantially reach that the consumption that masterbatch itself should possess is few, effective, function improves the features such as obvious, easy to use.
