Abstract
The invention discloses a preparation method of an antistatic agent and belongs to the field of chemical industry. The preparation method is characterized by including following steps: taking and placing PPW-g-MAH and micromolecule diethanolamine after going through polypropylene wax and maleic anhydride grafting treatment in a round-bottom flask, and adding a catalyst; adding dimethylbenzene, electromagnetically stirring under protection of nitrogen, cooling reaction liquid, and pouring the reaction liquid into alcohol to obtain white flocculent precipitate; using alcohol to soak a product for many times to remove free DEA; using a Buchner funnel for suction-filtering, and disposing a filter cake in an oven for drying to constant weight; mixing the filter cake with PP master batch, placing a mixture in an open mill for mixing, and tableting through a vulcanizing machine to prepare a diaphragm. By improving the preparation method, MAH in PPW-g-MAH is utilized as a bridging agent to graft micromolecule DEA to prepare a PPW-g-DEA antistatic agent which has good antistatic performance; the preparation method is simple in process, easy to operate and wide in application prospect.
Description
Technical field
The invention belongs to chemical field, particularly relate to a kind of preparation method of static inhibitor.
Background technology
Along with the fast development of economy, increasing novel material has been applied in our life, to the great convenience that the life of people brings, wherein, polypropylene because of its have good thermotolerance, chemical proofing, nontoxic, be easy to the features such as recovery and be able to widespread use.But again in its application process, when occurring friction, stripping or responding to, product surface accumulate static charge will be caused, even also can cause when electrostatic causes corona discharge or spark discharge catching fire or exploding, bring loss and injure even.
Summary of the invention
The present invention is intended to solve the problem, and provides a kind of preparation method of static inhibitor.
The preparation method of a kind of static inhibitor of the present invention, is characterized in that: comprise the steps:
(1) PPW-g-MAH of Poly Propylene Wax and maleic anhydride graft process and small molecules diethanolamine DEA that learns from else's experience is placed in round-bottomed flask, adds catalyzer, then adds dimethylbenzene, under nitrogen protection induction stirring, 150 DEG C of isothermal reaction 2h;
(2) reaction solution being cooled to 110 DEG C pours in ethanol, obtains white cotton flocks, product with alcohol immersion repeatedly, to remove free DEA, use Büchner funnel suction filtration, filter cake be placed in 80 DEG C of baking ovens and be dried to constant weight;
(3) PPW-g-DEA and the PP master batch mixing utilizing above-mentioned steps (2) to synthesize, mixing in mill, then prepare diaphragm through the processing of vulcanizer compressing tablet.
The preparation method of static inhibitor of the present invention, is characterized in that: described diaphragm thickness is 5.1mm.
The preparation method of static inhibitor of the present invention, is characterized in that: described diaphragm preparation technology parameter is: the screw speed of mill is 25 ~ 35r/min, and front temperature of rolling is 170 ~ 185 DEG C, after to roll temperature be 150 ~ 175 DEG C, vulcanizer temperature is 185 DEG C.
The preparation method of static inhibitor of the present invention, is characterized in that: the catalyzer described in described step (1) is methanesulfonic.
The preparation method of static inhibitor of the present invention, by the improvement to its preparation technology, the MAH in PPW-g-MAH is utilized to be bridging agent, grafting small molecules DEA, obtained PPW-g-DEA static inhibitor, prepared PPW-g-DEA has good antistatic property, utilize its and preparation method's technique of static inhibitor of the present invention is simple, easy handling, has a extensive future.
Embodiment
The preparation method of a kind of static inhibitor of the present invention, comprises the steps:
(1) PPW-g-MAH of Poly Propylene Wax and maleic anhydride graft process and small molecules diethanolamine DEA that learns from else's experience is placed in round-bottomed flask, adds catalyzer, then adds dimethylbenzene, under nitrogen protection induction stirring, 150 DEG C of isothermal reaction 2h;
(2) reaction solution being cooled to about 110 DEG C pours in ethanol, obtains white cotton flocks, product with alcohol immersion repeatedly, to remove free DEA, use Büchner funnel suction filtration, filter cake be placed in 80 DEG C of baking ovens and be dried to constant weight; The quality of PPW-g-DEA non-ionic antistatic agent performance depends on the content of polar hydroxyl groups, and hydroxy radical content is higher, and static inhibitor performance is more excellent.
(3) PPW-g-DEA and the PP master batch mixing utilizing above-mentioned steps (2) to synthesize, mixing in mill, then prepare diaphragm through the processing of vulcanizer compressing tablet.
The preparation method of static inhibitor of the present invention, described diaphragm thickness is 5.1mm.Described diaphragm preparation technology parameter is: the screw speed of mill is 25 ~ 35r/min, and front temperature of rolling is 170 ~ 185 DEG C, after to roll temperature be 150 ~ 175 DEG C, vulcanizer temperature is 185 DEG C.
The preparation method of static inhibitor of the present invention, the catalyzer described in described step (1) is methanesulfonic.Catalyzer is obvious to the esterification catalytic effect of the hydroxyl in PPW-g-MAH and alcohol amine structure, and the ester content in product increases, and therefore, decreases the quantity of synthetic product Semi-polarity functional group hydroxyl.
