The invention has the beneficial effects as follows:
(1) the present invention has obtained a kind of conductive plastics, becomes the raw material of conductive plastic object, is able to widespread use.
Description of drawings
In order to be illustrated more clearly in the embodiment of the invention or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the production technological process of conductive plastics of the present invention.
Embodiment
The present invention by adding acetylene black, obtains a kind of conductive plastics through extensive and deep research, then carries out the conductivity evaluation, thereby finishes the present invention.The production technological process of conductive plastics of the present invention as shown in Figure 1, step 10: each component is according to certain ratio, good with electronic balance weighing; Step 20: the raw material that weighs up carries out mixing in clean two roller mills; Step 30: the polyvinyl chloride that mixes, roll at plastic calender; Step 40: will roll good plastic sheet, putting into tablets press carries out granulation; In order to injecting or extruding use.
Polyvinyl chloride
The thermoplastic resin that under the initiator effect, is polymerized by vinylchlorid.It is the homopolymer of vinylchlorid.Ryuron and vinyl chloride copolymer are referred to as vinyl chloride resin.PVC has preferably mechanical property, about tensile strength 60MPa, and shock strength 5～10kJ/m
2Excellent dielectric properties are arranged; But the poor stability to light and heat; PVC is very hard, and solvability is also very poor, can only be dissolved in the minority solvents such as pimelinketone, ethylene dichloride and tetrahydrofuran (THF), and all stable to organic and mineral acid, alkali, salt, chemical stability reduces with the rising of use temperature.
In order to reach conductivity of the present invention, the polyvinyl chloride that the present invention adopts forms by mass polymerization.
Preferably, described polyvinyl chloride, its molecular weight are 100,000, and shock strength is 8kJ/m
2
Acetylene black
Shawinigan black is that manufacture gas decomposes the refining acetylene of purity more than 99% that obtains, the carbon black that obtains behind continuous pyrolysis during by calcium carbide route or petroleum naphtha (raw gasline) pyrolysis.With Reaktionsofen inside be warming up to acetylene decompose starting temperature more than 800 ℃ after, import acetylene and begin to carry out thermolysis.Because being thermopositive reaction, reaction can be carried out automatically.In order to obtain stable quality, temperature of reaction should remain on about 1800 ℃.Temperature can be controlled by Reaktionsofen urceolus water-cooling jacket in the stove.
Shawinigan black is compared with other carbon black has following characteristic: the light proportion of quality is little; The large adsorptivity of specific surface area is strong; Stable chemical nature; Good surface activity, electroconductibility is high; High purity, ash content and volatile matter are low.Contrast powdery acetylene black, dustless carbon black has volume and urinates in transportation, dust pollution minor benefit in improving the advantages such as environment for use, flowability and good dispersity.
Below in conjunction with specific embodiment, further set forth the present invention.The experimental technique of unreceipted actual conditions in the following example is measured according to national standard usually.If there is not corresponding national standard, then carry out according to general international standard, normal condition or according to the condition that manufacturer advises.Unless otherwise indicated, otherwise all umbers are weight part, and all per-cents are weight percentage, and described polymericular weight is number-average molecular weight.
Unless otherwise defined or explanation, same meanings of being familiar with of all specialties used herein and scientific words and those skilled in the art.Any method similar or impartial to described content and material all can be applicable in the inventive method in addition.
Embodiment:
100 parts of polyvinyl chloride, 3 parts of three salt, 1.5 parts of disalts, 1.5 parts of barium stearates, ACR4012 part, CPE8 part, 8 parts of active fine particle calcium carbonates, 5 parts of titanium whites, 1 part in OP wax, 8 parts of acetylene blacks, what play electric action mainly is acetylene black.
Processing condition are as follows:
Polyvinyl chloride is plasticated in two roller mills, and the roller temperature behind the bag roller, adds OP wax, barium stearate, CPE, three salt, disalt, ACR401, active fine particle calcium carbonate, titanium white, acetylene black below 60 ℃ successively, and/thin-pass is descended sheet six times afterwards.Before mixing, must keep roller clean, not have contaminated.The PVC that mixes rolls in rolling press.In flakes, put into granulator granulation.
The PVC particle is carried out one step cure at vulcanizing press, press vulcanization: 120 ℃ * sulfurizing time of one step cure; The plastic sheet that vulcanizates is pressed into the dumbbell shape test piece at sheet-punching machine and carries out mechanical property and conducting performance test.
Experimental result: tensile strength 52.3MPa; Temper elongation 46.5%; Shock strength 5.2KJ.m
-2Its mechanical property is close with the mechanical property of the PVC of routine.
Conductivity: usually resistance value is called isolator more than 1010 Ω cm; Resistance value is called semi-conductor or anti-electrostatic body in 104～109 Ω cm scopes; Resistance value is called electrical conductor below 104 Ω cm; Resistance value is below 100 Ω cm even lower be called high conductor.Then 6 points by test PVC surface average, and its resistance value is 102.3 Ω cm, can judge that the plastics that this prescription obtains are conductive plasticss.
