Description
Technical field
The present invention relates to PVC and preparation method thereof technical field, more particularly to a kind of praseodymium oxide coated glass fiber
Modified coal mine special PVC pipe of enhancing and preparation method thereof.
Background technology
Polyvinyl chloride（PVC）Resin be in our daily lifes the maximum thermoplastic resin of most widely used, consumption it
One, it has lightweight, good insulating, difficult to burn, strong mechanical performance, abundant, the manufacturing process maturation of cheap, raw material sources etc.
Feature, thus be used widely in the fields such as coal mine pipes for mining material.However, it is also in the presence of rushing that some are difficult to overcome
Hit poor performance, the shortcomings of heat endurance is not good enough, in order to overcome many scholars of the disadvantages described above of polyvinyl chloride in PVC toughening modifying sides
Face has carried out substantial amounts of research, and current glass fibre has been progressed into the visual field of PVC study on the modification persons, such as document《Glass
The preparation of fiber/polyvinyl chloride composite materials and performance study》Glass fibre/PVC is prepared for using injection molding method（Polychlorostyrene second
Alkene）Composite.Result of study shows：When shaping penetrate pressure for 130MPa, pressurize be 100MPa, back pressure be 0.5MPa, shaping temperature
Spend for 420 DEG C, mold temperature are 100 DEG C and w（Glass fibre）=15%（For composite quality）When, composite
Combination property it is relatively best, its tensile strength（77.4MPa）And shear strength（57.4MPa）Relative maximum, and product table
The smooth color in face is normal, and the pure PVC of bending strength ratio improves 68.4%.
It is well known that colliery is a special operating environment, dark, moist, narrow space has falling rocks sometimes, this
Being accomplished by PVC will not only have enough impact strengths, also there is the property such as antistatic, fire-retardant, wear-resisting, antibacterial, anti-corrosive properties
Energy.Yet with polyvinyl chloride high-insulation, its sheet resistance is up to 1014 Ω or so, and this insulating properties usually make polychlorostyrene second
Alkene manufactured goods produce electrostatic during production, accumulating, use and easily cause blast accident, and are not carried out in document antistatic
It is modified, in addition due to glass fibre and polyvinyl chloride poor compatibility, the shock resistance of obtained polyvinyl chloride composite materials in document
Property, shear strength, tensile strength etc. cannot meet the technical indicator of coal mine pipes for mining requirement, and wear-resisting, antibacterial, anti-corrosive properties compared with
Difference, disadvantages described above limits popularization and application of the polyvinyl chloride in underground coal mine.To improve disadvantages described above, it is necessary to existing production work
Skill and formula rate are improved, and have the advantages that tensile strength is high, antistatic, wear-resisting, Antimicrobial preservative is ageing-resistant to prepare
The mining effective modified polyvinyl chloride of underground coal mine.
The content of the invention
The object of the invention is exactly to make up the defect of prior art, there is provided a kind of praseodymium oxide coated glass fiber enhancing changes
Coal mine special PVC pipe of property and preparation method thereof.
The present invention is achieved by the following technical solutions：
A kind of modified coal mine special PVC pipe of praseodymium oxide coated glass fiber enhancing, is made from the following raw materials in parts by weight：
Polyvinyl chloride resin 100, glass fibre 14.3-15.3, ABS resin 13-15, tourmaline powder 19-21, praseodymium oxide 3.7-3.9, aramid fiber are fine
Dimension 7.2-7.7, methyl tributanoximo silane 5.8-6.2, dibutyl tin 0.9-1.3, ATEC 2.7-3.2,
Microcrystalline wax 3-5, appropriate amount of water.
A kind of preparation method of the modified coal mine special PVC pipe of described praseodymium oxide coated glass fiber enhancing, including
Following steps：
（1）Praseodymium oxide, methyl tributanoximo silane are scattered in dispersion liquid is formed in suitable quantity of water, added glass fiber impregnated
10-12 hours, the glass fibre of praseodymium oxide coating is obtained after taking-up by baking；
（2）Tourmaline powder is calcined 1-2 hours in 830-930 DEG C, cooling adds dibutyl tin, microcrystalline wax to be put into ball mill
Ball milling 2-3 hours, dry to obtain modified verdelite powder；
（3）ABS resin is heated to molten condition, adds aramid fiber to be granulated after stirring and evenly mixing；
（4）Polyvinyl chloride resin is put into drying box and is processed 6-8 hours in 110-115 DEG C, sealing preserve is standby；
（5）By step（4）Polyvinyl chloride resin input double screw extruder in, add step（1）、（2）、（3）Material and other residues
Components fuse is blended and granulates and to obtain stuff and other stuff；
（6）Finally by step（5）Stuff and other stuff is put into injection moulding in plastic injection molding machine, discharging.
It is an advantage of the invention that：Praseodymium oxide is coated on glass fibers dimension table by the present invention through methyl tributanoximo silane coupling
Face is added in raw material as reinforcing material, on the one hand improves compatibility of the glass fibre in PVC matrix, on the other hand,
When during external impacts, the impulsive force that PVC matrix is subject to is transferred to be undertaken on glass fibre and by it, causes glass fibers
Dimension fracture absorbs substantial amounts of energy from PVC matrix, so as to reach the purpose of toughness reinforcing；The present invention also changes tourmaline powder simultaneously
Property treatment be added in raw material as modified filler, improve the ageing resistace of product, then compatibility adds other effective auxiliary agents
Obtained pvc pipe is used in the well environment of colliery, excellent with ageing-resistant, intensity oil resistivity high, excellent and relatively low temperature in use etc.
Point.
