Pillar and preparation method thereof.
Background technology
Polypropylene (Polypropylene, abbreviation PP) is a kind of hemicrystalline thermoplastic, has raw material sources rich
Richness, the impact resistance that mechanical property is good, density is small, higher, resist the advantages that a variety of organic solvents and acid and alkali corrosion；Have in industrial quarters
It is widely applied, is one of usually common high polymer material；But because PP Chain Flexibilities are big, melt extrusion elasticity is big,
PP application is limited to a certain extent；In order to improve polyacrylic processing characteristics, expand its application, both at home and abroad to modification
PP has done many researchs；
Power pipe is also known as cable protection pipe, and it is mostly installed at the location that communication cable intersects with power line, prevents electric power
Line occurs broken string and causes short circuit accident, causes communication cable and steel wire rope powered, to protect cable, interchanger, machine core board, so that
Complete machine is not burned, and certain buffer action is also played to power line magnetic interference；
MPP power pipes are the plastic pipes for using modified polypropene to be prepared for main raw material(s), and MPP power pipes are current cities
One of most conventional electric power tubing mainly applied on field, but with the gradual expansion of its application field and environment, its weak point
Also increasingly highlight, can't in terms of such as anti-flammability, electrical insulating property, antiacid caustic corrosion, sliding, heat endurance combination property
The environment of high request is adapted to completely, therefore the comprehensive of polypropylene electric power protection pipe is improved by filling-modified or blending and modifying
Can, obtain corrosion resistance is strong, electric insulating quality is good, high mechanical strength, coefficient of friction are small, fire-retardant, suppression cigarette, it is heat-resisting, cold-resistant, use
Long lifespan, the electric power protection pipe that easy for construction, the ratio of performance to price is superior are the hot issues studied at present；Therefore, learn both at home and abroad
Art circle and industrial circle have carried out numerous studies to improve the performance of PA tube；
CN102276913A discloses a kind of MPP push pipes polypropylene material, and it is made up of following component:Lazy flow homopolymerization gathers

40wt%, antioxidant and nucleator 0.1-4wt%, composite pigment 0.1-3wt%, the inside and outside lubricant agent 1- used in high polymer material
5wt%；Change material on the premise of ensureing that later stage production is stable, at the same ensure material have very high tenacity, high tensile strength,
Fine bending strength and weld strength and long service life, but the combination property of the invention not research material is for example heat-resisting
Property, corrosion resistance, anti-flammability etc.；CN104151703A discloses a kind of MPP power pipes of high-fire resistance energy, the power pipe
Using MPP and CaCO3For primary raw material, and add plasticizer, compatilizer, stabilizer, anti-impact modifier, fire retardant, antioxygen
The various ingredients such as agent, lubricant are prepared, and although the power pipe obtains preferable heat resistance, but raw material uses composition
It is complicated, it is difficult to obtain the product of stable homogeneous；In addition, for the characteristic of PA tube low-temperature flexibility difference, to polypropylene
Learn be modified, elastic phase is introduced in polypropylene matrix, so as to improve the low-temperature flexibility of polypropylene pipe (Tan, H.Li,
L. Chen, Z. Song, Y. Zheng, Q., Polymer, 2005, 46,:3522)；For pressure pipeline ring by
The characteristics of power is about twice of axially loaded, Chen et al. (Chen K.Y., Zhou N.Q., Liu B., Jin G.,
Journal of applied polymer science,2009,114:3612) using the Periodic Rotating of extrusion screw rod with before
Precession afterwards produces Vibrational force field, obtains the PA tube of two-dimentional self-reinforcing, its ring intensity is improved；It is but above-mentioned to grind
Comprehensive improvement can't be carried out to the combination property of MPP power pipes on the whole by studying carefully, and can not be obtained multinomial performance while be taken on a new look
MPP power pipes.
