Abstract
The invention relates to a sun-proof composite modified polypropylene pipe for power cable protection. The pipe comprises the following components in percentage by weight: 73 to 78 percent of PP (Propene Polymer), 10 to 15 percent of POE (Polyolefin Elastomer), 4.8 to 5.2 percent of nano calcium carbonate, 0.3 to 0.4 percent of nucleating agent, 0.2 to 0.25 percent of coupling agent and 0.5 to 1 percent of sun-proof lubricating composite functional master batch. Not only does the pipe have better low-temperature impact resistance, wherein impact energy in a falling weight impact test at a temperature of minus 5 DEG C is improved by over 2.5 times, the friction coefficient is reduced by 40 percent and the Vicat heat-resistance temperature is risen by 5 DEG C, but also sun-proof performance of the pipe is improved and the application range of the power pipe is enlarged.
Description
Technical field
The present invention relates to the tubing field, be specifically related to a kind of power cable protection sun-proof type composite modified polypropylene tubing.
Background technology
Raw materials used polyvinyl chloride and the high density polyethylene(HDPE) of mainly concentrating on of tubing of present market.Along with the raising of environmental protection consciousness, polyvinyl chloride is progressively withdrawn from the market, and compares with polyethylene, and polypropylene has higher Young's modulus and lower density, and cost performance is higher.
But poor toughness especially is easy to occur brittle rupture under low temperature environment because the vertical rigidity of polypropylene is higher, has a strong impact on the work-ing life of tubing.Simultaneously in view of present excavation power engineering because of long in time limit, south particularly, storage period is long on-site, intensity of illumination is high for tubing, causes easily tubing aging, as color shoal, the problem such as material is rotten.
So composite strengthening single-wall corrugated pipe material how to produce rigidity height, good toughness and high temperature resistant sun-proof becomes this area urgent problem.
Summary of the invention
In order to solve the deficiencies in the prior art, the invention provides a kind of power cable protection sun-proof type composite modified polypropylene tubing.This tubing is tool low-temperature impact resistance preferably not only, the impact energy of-5 ℃ of falling weight impact tests improves more than 2.5 times, and frictional coefficient reduces by 40%, and dimension card heat resisting temperature improves 5 ℃, and improved the sun-proof performance of tubing, enlarged the range of application of electric power tubing.
In order to solve the deficiencies in the prior art, the present invention by the following technical solutions: a kind of power cable protection by weight percentage, comprises following component with sun-proof type composite modified polypropylene tubing:
PP 73-78%
POE 10-15%
Nano-calcium carbonate 4.8-5.2%
Nucleator 0.3-0.4%
Coupling agent 0.2-0.25%
Sun-proof lubricates composite function master batch 0.5-1%
By weight percentage, also include the 3%-3.8% wire, 3%-3.3% modified capsaicin, described modified capsaicin are a kind of capsaicines that adopts after organic substance wraps up.
The lubricated composite function master batch of described sun-proof comprises photostabilizer, composite thermal stabilizer, free radical cancellation trapping agent, dispersion agent.
Described nucleator model is ZC-3, XL-NA2002 or CaV102.
Described coupling agent is vinyl three (b-methoxy ethoxy) silane, γ-(methacryloxypropyl) propyl trimethoxy silicane or γ-aminopropyl triethoxysilane.
Described POE model is produced by U.S. DOW company for being 8198.
The above-mentioned power cable protection preparation method of sun-proof type composite modified polypropylene tubing comprises following processing step:
A prepares PP, POE, nano-calcium carbonate, nucleator, coupling agent, sun-proof lubricated composite function master batch, wire and modified capsaicin at first in proportion, and described ratio is 73-78%:10-15%:4.8-5.2%:0.3-0.4%:0.2-0.25%:0.5-1%:3%-3.8%: 3%-3.3%;
Then b puts into each component in the molding device, then cools off in order, traction, cutting on line, lettering, warehouse-in after the assay was approved.
Of the present invention have a beneficial effect: the present invention adopts polynary compound blending and modifying principle; in the PP resin, add the lubricated composite function master batch of POE, nucleator, nano-calcium carbonate, coupling agent and sun-proof; by obtaining modified PP after the blend granulation, then obtain power cable protection sun-proof type composite modified polypropylene tubing by extruding-out process.
Owing to added POE, it has good mechanical property and processing characteristics, and the thermoplasticity of existing plastics has again the elasticity of rubber, and with PP good affinity is arranged, and is the effective anti-impact modifier of PP, has increased the toughness of PP.
In order to increase the strength and modulus of PP, also adopt nano-calcium carbonate that the PP/POE alloy is carried out modified synergic.
Because the nano-calcium carbonate that adds surface oleophilic drainage is good with resin compatible, can Effective Raise or regulate goods just, toughness, smooth finish and flexural strength; Improve processing characteristics, rheological property, dimensional stability, the heat-resistant stability that improves goods has filling and enhancing, toughness reinforcing effect, can replace the expensive stopping composition of part and help Ji, reduces the consumption of resin, thereby reduce the products production cost, improve the market competitiveness.
Add nucleator in PP, can accelerate crystallization velocity, form the spherocrystal of tiny densification, make molecular chain have very fast crystallization velocity under comparatively high temps, and the spherocrystal number is many, size is little.Thereby improve the performance of PP, realize the high performance of PP.There is significant synergy between different nucleators or nucleator and other auxiliary agent, can significantly improves the performance of PP.
Adding the lubricated composite function master batch of sun-proof in material acts synergistically to the frictional coefficient of tubing and sun-proof and lubricity.Make simultaneously PP under the impact of the factors such as ultraviolet ray, infrared rays, the number of the free radical of generation and molecule chain break has all obviously reduced, and has increased the life-span of PP, improves the sun-proof performance of PP.
Eventually the above, the present invention's component and content thereof preferred, make each component see that synergistic effect reaches best, solved problems of the prior art, made not only tool low-temperature impact resistance preferably of this tubing, the impact energy of-5 ℃ of falling weight impact tests improves more than 2.5 times, frictional coefficient reduces by 40%, dimension card heat resisting temperature improves 5 ℃, and has improved the sun-proof performance of tubing, has enlarged the range of application of electric power tubing.
Further beneficial effect of the present invention is: add wire and play the effect of strengthening tube wall, just as the reinforcing bar in the cement, in addition can in case mouse sting, wire has powerful fastness, do not allow easily brokenly, can strangle in the teeth space of mouse, it is damaged, shape wiry can be very thin flat, and its injury ability that embeds the mouse teeth space is stronger.Wire is had no progeny in addition, also can prick pain mouse face.Wire can be the aluminium wire of flat.Add simultaneously the higher capsaicine of content, produce the smell that the taste and smell of muroid or insect is had intense stimulus, can effectively prevent muroid or termite to the injury of baiting of tubing, being particularly useful for need to be with the tubing under the lowered in field environment.
