Abstract
The invention relates to water absorbing parent material, which comprises carrier resin, rectorite and processing ingredient. The weight percentage of the three components is as follows: 95 to 3 percent of carrier resin, 4 to 95 percent of rectorite, and 1 to 10 percent of processing ingredient. The production method of the water absorbing parent material of the invention comprises the following steps: the blended carrier resin, rectorite and processing ingredient is put into a high speed mixer to be agitated at high speed or internally mixed through an internal batch mixer, and then delivered to a double screw extruder to be extruded and granulated. In the production of the plastic products, the parent material of the invention is added, which can ensure that the product surface has no bubble, ter wave or crack, and ensure the that the product surface is smooth and artistic, and the obtained product has good tenacity, high temperature resistance and good anti-extrusion performance, and the intensity is obviously improved. In addition, if the parent material of the invention is used, the generation of foreign flavor during the manufacturing process can be effectively reduced.
Description
Technical field
The invention belongs to the plastics field, relate to the masterbatch of using in a kind of plastics production, specifically a kind of absorbent masterbatch and production method thereof.
Background technology
During plastics were produced in the market, the absorbent masterbatch routine of using was to be main raw material(s) with calcium oxide, is calcium oxide as absorbent masterbatch main raw material(s) in polyethylene (PE) film production.And this masterbatch is bigger to the extrusion equipment wearing and tearing, can reduce the shock strength of polyethylene (PE) macromolecular material greatly, and it also can't remove the peculiar smell of regeneration strip.
Summary of the invention
The objective of the invention is to develop a kind of absorbent masterbatch and production method thereof.
The present invention will solve is traditional be that the masterbatch of main raw material is big to the extrusion equipment wearing and tearing, the shock strength that can reduce plastics greatly, can't remove the problem of regeneration strip peculiar smell etc. with calcium oxide.
Technical scheme of the present invention is, it comprises vector resin, rectorite and processing aid, and the weight percent of these three kinds of components is: vector resin 95%--3%, rectorite 4%---95%, processing aid 1%--10%; The vector resin that proportioning is good, rectorite and processing aid place high mixer high-speed stirring or Banbury mixer banburying, then send the twin screw extruder extruding pelletization.
Advantage of the present invention is: producing plastics, adds masterbatch of the present invention, can make product surface not have bubble, and no water wave, leakless is guaranteed the product surface smooth and beautiful appearance, and the toughness of resulting product, high thermal resistance, anti-extrusion good especially, intensity obviously improves.Add masterbatch of the present invention in this external course of processing, can also adsorb the peculiar smell of original plastics, effectively reduce the generation of peculiar smell in the course of processing.
Specific implementation method
Absorbent masterbatch of the present invention comprises vector resin, rectorite and processing aid, and the weight percent of these three kinds of components is: vector resin 95%--3%, rectorite 4%--95%, processing aid 1%--10%.Described vector resin comprises polyethylene (PE), polypropylene (PP), ethylene/vinyl acetate multipolymer (EVA), ethylene/ethyl acrylate multipolymer (EEA), polyamide (PA), acrylonitrile/butadiene/styrene multipolymer (ABS), polystyrene (PS) and polyvinyl chloride (PVC), selects a kind of vector resin wherein during batching at least for use.Described rectorite comprises sodium base rectorite or calcium base rectorite, selects wherein a kind of during batching at least for use.Described processing aid comprises oxidation inhibitor, lubricant, coupling agent, dispersion agent, selects wherein a kind of during batching at least for use.
The production method of absorbent masterbatch of the present invention is: the good vector resin of proportioning, rectorite and processing aid are placed high mixer high-speed stirring or Banbury mixer banburying, then send the twin screw extruder extruding pelletization.
Now be described further in conjunction with specific embodiments.
