Abstract
The invention relates to a corrosion resistant polypropylene, comprising by weight 50.5-85% of polypropylene, 5-35.5% of corrosion inhibitor, 2.5-30% of conductive graphite, 0.1-1.0% of anti-oxidant, 0.2-2.0% of flexibilizer and 0.2-5.5% of active carbon. The corrosion resistant polypropylene of the invention can substitute metal raw material to produce installation kit or shell, has good performance of convenience for processing of a thermoplastic, electromagnetic shielding function, and is convenient for producing and purchasing and at low costs; besides the corrosion resistant polypropylene has characteristics of acid and alkali corrosion resistance, certain mechanical strength and temperature toleration.
Description
Technical field
The present invention relates to a kind of organic polymer composite, more particularly, relate to a kind of anticorrosive polypropylene.
Background technology
At present, the application with the plastics alternative metals constantly enlarges in the world, and scientist all over the world actively seeks new functional thermoplastics through various tests, also becomes enterprise and strives for more families and the important component part of extending volume growth.
But the electroconductibility of metal and capability of electromagnetic shielding are that common plastics are not available.And, all relate to the part that need have electro-magnetic screen function at present in civil electronic electrical equipment/toy/communication/cable/many fields such as military project.This series product market basically all has to use raw material metal production at present, and it is big to stand the process for processing difficulty, and link is many, and cost is high, a series of shortcomings that production efficiency is low or the like.These are the present invention's problem that will solve just.Do not needing higher heatproof requirement; Have simultaneously when requiring in certain intensity and heatproof and work-ing life; Can use and of the present inventionly have the electro-magnetic screen function polypropylene and carry out injection moulding or extrude production as starting material; Cost reduces significantly; The raising of production efficiency several times contributes for the lightweight of product and returnability simultaneously; The advantage that also has the not available acid-alkali-corrosive-resisting of raw material metal simultaneously.
Summary of the invention
The objective of the invention is to effectively overcome the defective of prior art, a kind of environmental protection electromagnetic shielding polypropylene starting material of can the alternative metals starting material producing spare and accessory parts or shell are provided.
Technical scheme provided by the invention is following: anticorrosive polypropylene, by following composition by weight forming polypropylene: 50.5-85%, corrosion inhibitor: 5-35.5%; Electrically conductive graphite: 2.5-30%; Antioxidant: 0.1-1.0%; Toughner: 0.2-2.0%; Gac: 0.2-5.5%.
Anticorrosive polyacrylic preparation method of the present invention; Comprise the steps: polypropylene is made into about 30% the aqueous solution; Add in the reaction kettle; Temperature in the reaction kettle is controlled at 60～80 ℃ and under normal pressure, stir; When stirring, slowly add a certain proportion of corrosion inhibitor, electrically conductive graphite, antioxidant, toughner; After reaction finishes,, can obtain 50% polypropylene salt brine solution with active carbon purifying, filtration.Salt-forming reaction is thermopositive reaction, recirculated water cooling beyond the reaction heat must be removed for this reason, and is oxidized for preventing that polypropylene salt from contacting with air simultaneously, in production system, fills with nitrogen protection.Under vacuum state, the polypropylene salt brine solution with 50% through evaporation, dehydration, concentrate, crystallization, drying, can obtain solid polypropylene salt.
Wherein, electrically conductive graphite serves as softening agent and adds wear-resisting wiping, the abrasion resistance properties that can improve plastics; The adding of corrosion inhibitor can improve the resistance to corrosion of plastics greatly, makes improve the work-ing life of plastics; The adding of toughner can be difficult for taking place the embrittlement phenomenon so that the plastic tape flexible, the adding of these several reagent can both improve that original plastics possess some have the performance of defective.
Anticorrosive polyacrylic advantage of the present invention: can produce spare and accessory parts or shell by the alternative metals starting material; He promptly have simultaneously thermoplastics good be convenient to processing characteristics; The electro-magnetic screen function that has simultaneously metal material again; Thereby production procurement is convenient; Relevant cost declines to a great extent; Also have characteristics and the certain mechanical strength and the temperature tolerance of acid-alkali-corrosive-resisting simultaneously, improved competitive power like this.
Embodiment
Below be the most preferred embodiment of electromagnetic shielding polypropylene raw material of the present invention, therefore do not limit protection scope of the present invention.
Embodiment one, and a kind of electromagnetic shielding polypropylene raw material is provided, by following composition by weight forming polypropylene: 70%, corrosion inhibitor: 30%; Electrically conductive graphite: 7%; Antioxidant: 1.5%; Toughner: 0.5%; Gac: 1.0%.
Polypropylene is made into about 30% the aqueous solution; Add in the reaction kettle; Temperature in the reaction kettle is controlled at 60～80 ℃ and under normal pressure, stir; When stirring, slowly add a certain proportion of corrosion inhibitor, electrically conductive graphite, antioxidant, toughner; After reaction finishes; With active carbon purifying, filtration, can obtain 50% polypropylene salt brine solution.Salt-forming reaction is thermopositive reaction, recirculated water cooling beyond the reaction heat must be removed for this reason, and is oxidized for preventing that polypropylene salt from contacting with air simultaneously, in production system, fills with nitrogen protection.Under vacuum state, the polypropylene salt brine solution with 50% through evaporation, dehydration, concentrate, crystallization, drying, can obtain solid polypropylene salt.
The above; It only is the specific embodiment of the present invention; But protection scope of the present invention is not limited thereto; Any those of ordinary skill in the art are in the technical scope that the present invention disclosed; Variation or the replacement that can expect without creative work all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
