Description
Technical field
The present invention relates to macromolecule modified field, more particularly to a kind of polychloroethylene composition material and preparation method thereof.
Background technology
Mine special equipment is chiefly used in underground mining operation or mineral products conveying, in the whole process frequent dust from flying, pole
Be also easy to produce explosion, fire hidden danger, therefore the plastic material used for mine special equipment needs antistatic requirement.But at present
Antistatic plastic material mostly use surfactant type antistatic agent, be that non-permanence is antistatic, resist generally after the 1-2
Electrostatic efficiency disappears, and needs that better antistatic effect could be obtained in the environment of high humility, disappears in antistatic effect
It loses rear surface and easily adsorbs dust, considerably increase the risk of dust explosion.Currently used permanent type antistatic agent is polyethers
Type antistatic agent, conductive black or conductive carbon nanotube have seriously affected material although can reach permanent antistatic requirement
Performance, considerably increase the risk of equipment damage.How the contradiction of the physical property and permanent antistatic property of material is solved,
It is urgent need to solve the problem in current pit gear material selection.
Invention content
The purpose of the present invention is to provide a kind of polychloroethylene composition material and preparation method thereof, set for mine to be special
It is standby, particularly suitable for products such as underground equipment shell, internal product, conveyer belt and its attachmentes, do not influencing raw material itself
While machinery, thermal property, excellent permanent antistatic property is had both.
To achieve the above object, present invention employs following technical schemes:
A kind of polychloroethylene composition material is made of following components by its parts by weight:
Polyvinyl chloride:1000 parts,
Carbon black:1-5 parts,
Tetrabromobisphenol A:1-5 parts,
Antioxidant:2-5 parts,
Heat stabilizer:The weight part ratio of itself and polyvinyl chloride is 2-3:100,
Lubricant:The weight part ratio of itself and polyvinyl chloride is 1-2:100.
Further, the polyvinyl chloride is loose type, specific viscosity 0.26-0.29, average degree of polymerization 650-700.
Further, the DBP absorption values of the carbon black are 380cm3/ 100g, BET surface area 950m2/g。
Further, the heat stabilizer is the mixture being made of organic tin stabilizer, zinc stearate and calcium stearate, and
The weight percent of each component is in every part of heat stabilizer:Organic tin stabilizer 60%, zinc stearate 25%, calcium stearate
15%.
Further, the lubricant is polyethylene wax or oxidized polyethylene wax.
Further, the antioxidant is selected from antioxidant 1076 (18 carbon of β-(3,5- di-t-butyl hydroxy phenyl) acrylic acid
Acid esters), irgasfos 168 (three-(2,4- tert-butyl-phenyls) phosphite esters), antioxidant 1010 (Si [β-(3,5- di-t-butyls-
4- hydroxy phenyls) Bing Suan ]One or both of pentaerythritol ester) and antioxidant DLTDP (thiodipropionic acid bis-dodecanol ester)
Above mixture.
A kind of preparation method of polychloroethylene composition material, includes the following steps:
By the parts by weight of each component of the polychloroethylene composition material, by polyvinyl chloride, heat stabilizer, antioxidant
With lubricant be added high mixer in mixed, at 70-90 DEG C mix 5-10min after, continuously added in high mixer carbon black,
Tetrabromobisphenol A remixes 5-10min;Then uniformly mixed material is sent by feed device in double screw extruder and is squeezed
Go out to be granulated, material adequately fuses under the shearing, mixing and conveying of screw rod, is finally made poly- after extrusion, tie rod, cooling
Vinyl chloride composition finished material.
Further, each zone temperatures of the double screw extruder are set as 160-170 DEG C of an area, two area 180-190
DEG C, three 190-220 DEG C of areas, four 220-270 DEG C of areas.
The present invention has following advantageous effect:
1, polychloroethylene composition material provided by the present invention has excellent mechanical property, processing performance excellent.
2, common surfactant type antistatic agent, antistatic principle are the water in absorption air after surface is precipitated
The water layer of vapour, abutment surface takes away charge, will there is no antistatic effects after the surfactant in matrix is all migrated to surface
Fruit, it is antistatic to be consequently belonging to non-permanent type, and the tetrabromobisphenol A that the present invention uses and carbon black are used in compounding (antistatic based on carbon black
Agent, tetrabromobisphenol A act as auxiliary antistatic agent), good dispersion in resin matrix is added as compounding antistatic agent, it can be with
Form Filamentous or netted form does not influence machinery, the thermal property of original material because additive amount is seldom.Composition material has
Permanent anlistatig characteristic, does not decay with the increase of usage time, and the problems such as being precipitated also is not present.
3, containing organic tin stabilizer 60%, zinc stearate 25%, calcium stearate 15% in heat stabilizer, extraordinary heat is steady
Determine agent to solve in process, the problem of Partial digestion can occur for raw material.
4, the pvc material that the present invention uses is highly suitable for the confrontation electrostatic grade such as winning equipment, underground equipment
It is required that high product, is also suitable for other and needs permanent anlistatig product.
