Description
Technical field
The present invention relates to a kind of high-strength, high-anti-friction polyvinyl chloride nano matrix material for the manufacture of carrying roller.
Background technology
Carrying roller is the vitals of endless belt conveyor, and kind is many, and quantity is big.The effect of carrying roller is support belt and weight of material, the necessary flexibility and reliability of carrying roller running, reduce conveying belt with the frictional force of carrying roller, though carrying roller is a small parts in endless belt conveyor, structure is also uncomplicated, but produce high-quality carrying roller not a duck soup, polymer carrying roller select materials mainly contains ultrahigh molecular weight polyethylene(UHMWPE) at present, nylon and polyoxymethylene, because the carrying roller that is used for using under the coal mine needs that flame retardant properties is had higher asking of wanting, so ultrahigh molecular weight polyethylene(UHMWPE), when being used for carrying roller, nylon and polyoxymethylene need add a large amount of fire retardants at prescription, could solve fire-retardant requirement, thereby cause that the Material Physics mechanical property descends.And that polyvinyl chloride (PVC) has is fire-retardant, chemical proofing is high, physical strength and the good advantage of electrical insulating property, but its wear resisting property poor than ultrahigh molecular weight polyethylene(UHMWPE) and nylon-6.Therefore, the wear resistance that how improves the PVC carrying roller under the condition that guarantees mechanical property is the purpose that the present invention studies.
Summary of the invention
The object of the present invention is to provide a kind of high-strength, high-anti-friction polyvinyl chloride nano matrix material for the manufacture of carrying roller.For improving the wear resisting property of material, the present invention has obtained the good pvc material of wear resisting property by add silicon carbide whisker in prescription.
The present invention adopts following technical scheme:
The present invention prepares burden by following prescription: polyvinyl chloride resin 75-90 part, nanometer silicon carbide whiskers 1-5 part, one package stabilizer 4-9 part, chlorinated polyvinyl chloride (CPE) 5-10 part, calcium stearate 0.3-0.8 part, stearic acid 0.2-0.7 part, polyethylene wax 0.1-0.3 part, processing rheological agent ACR0.1-0.3 part, antimonous oxide (Sb
2O
3) 3-6 part, static inhibitor 2-5 part, graphitized carbon black 4-8 part (above is weight part).
Wherein, the polymerization degree of polyvinyl chloride resin is preferably 1300 or 1000.
Wherein, the S-1000 or the S-1300 that produce for the suspension polymerization mode of described polyvinyl chloride resin.
Wherein, described processing rheological agent is ACR or MBS.
Wherein, described thermo-stabilizer is calcium zinc, organotin or lead salt.
Wherein, described static inhibitor is ionic anti-static agent, graphitized carbon black.
It is the single crystal fibre with certain length-to-diameter ratio (the preferred 50-300 of length-to-diameter ratio) that the present invention adopts nanometer silicon carbide whiskers, and it has goodish high temperature resistant property, very high strength and splendid wear resisting property.Nanometer silicon carbide whiskers is added in the pvc material for the manufacture of carrying roller, and the physical strength of pvc material improves a lot, and especially wear resisting property has significantly and improves.
Filling a prescription after the weighing in temperature by the present invention is to mix 10 minutes in 100 ℃ of high-speed mixers, be banburying 3 minutes in 200 milliliters of Banbury mixeies of 170 ℃ in the torque rheometer temperature again with the material that mixes, the molten materials that banburying is good the roller temperature be about 170 ℃ two roll plastic mixing mill up and down thickness be about the flap of 2mm, be that 175 ℃ flat board compacting thickness is the test piece of 2mm and 4mm with this flap in temperature, the sample that processes standard-required with processing units is tested then, and the performance of material sees Table 1:
Table 1 material property of the present invention
Embodiment
The invention will be further described to use embodiment 1-4 and comparative example 1-2 below, and the present invention is not limited to this.
Adopting the polyvinyl chloride (S-1000 and S-13000) of Qilu Petrochemical company chlor-alkali plant is material of main part, it is in 100 mass parts, according to the listed formulation of table 2 meet requirement of the present invention with calcium zinc as thermo-stabilizer, with CPE as toughner, with antimonous oxide as synergistic fire retardant, with graphitized carbon black as static inhibitor with the PVC blend of nanometer silicon carbide whiskers as anti-wear agent, with ACR as processing auxiliary rheological agents embodiment 1-4.Adopt similar distribution, use graphite for comparing 1, do not use nanometer silicon carbide for comparing 2.
