Abstract
The invention discloses a method for prolonging the storage time and service life of a petroleum resin product. The method comprises the following steps: performing cationic polymerization to obtain polymer liquid by taking pentane as a solvent, aluminum trichloride as a catalyst and monoolefine and 1,3-pentadiene as raw materials; performing alkaline washing and water scrubbing so as to deactivate the catalyst and remove the catalyst and other impurities; performing normal-pressure and reduced-pressure stripping to remove the pentane solvent and oligomer; and adding a liquid antioxidant before granulating and packaging. According to the method for prolonging the storage time and service life of the petroleum resin product disclosed by the invention, the resin product added with the antioxidant is better than the resin products without the antioxidant in terms of storage time and service life.
Description
Technical field
The present invention relates to and a kind ofly improve the storage of petroleum resin products and the method in work-ing life.
Background technology
At present, there is the existence of the problems such as storage time short, use procedure oxidation is serious in petroleum resin great majority market produced.
Summary of the invention
The technical problem to be solved in the present invention overcomes existing defect, provides a kind of storage of raising petroleum resin products and the method in work-ing life that effectively can strengthen storage time and work-ing life.
Object of the present invention carrys out specific implementation by the following technical programs:
Improve the storage of petroleum resin products and the method in work-ing life,
1) take pentane as solvent, aluminum chloride is catalyzer, with monoolefine, m-pentadiene for raw material, carries out cationoid polymerisation, obtain polymer fluid;
2) wash through subtracting and wash, make catalyst deactivation, removing catalyzer and other impurity;
3) then pentane solvent and oligopolymer is removed through normal, steam stripping at reduced pressure;
4) liquid antioxidant is added before entering granulation packaging again.
Preferably, in described step 4), the add-on of oxidation inhibitor is the 0.064wt% of raw material total feed.
Preferably, the polyreaction of described step 1), carries out in carbon five tripping device.
Beneficial effect of the present invention:
The storage of raising petroleum resin products provided by the invention and the method in work-ing life, add the rosin products that the rosin products after oxidation inhibitor did not add oxidation inhibitor before the life-span of storage time and use procedure is all better than.
Accompanying drawing explanation
Accompanying drawing is used to provide a further understanding of the present invention, and forms a part for specification sheets, together with embodiments of the present invention for explaining the present invention, is not construed as limiting the invention.In the accompanying drawings:
Fig. 1 is the inventive method schema.
Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the present invention, is not intended to limit the present invention.
Improve the storage of petroleum resin products and the method in work-ing life, see Fig. 1,
1) take pentane as solvent, aluminum chloride is catalyzer, with monoolefine, m-pentadiene for raw material, carries out cationoid polymerisation, obtain polymer fluid in carbon five tripping device;
2) wash through subtracting and wash, make catalyst deactivation, removing catalyzer and other impurity;
3) then pentane solvent and oligopolymer is removed through normal, steam stripping at reduced pressure;
4) add liquid antioxidant before entering granulation packaging again, the add-on of oxidation inhibitor is the 0.064wt% of raw material total feed.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, although with reference to previous embodiment to invention has been detailed description, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
