Description
Technical field
The invention belongs to the material technology field; be specifically related to a kind of carbon fibre rigid cable engineering pipe and preparation method thereof; this product is mainly used in optical cable, cable, cable jacket protection, is widely used in the electrical network enlargings and transformation field such as communication, electric power, urban construction, municipal administration, industrial civil building, road and bridge.
Background technology
As everyone knows, the cable work pipe that uses in the market, mostly adopt CPVC, VPVC and Glass Steel Tube, the defectives such as CPVC pipe rigidity is low, the flexible distortion of insufficient strength, heat-drawn wire are low have had a strong impact on the expansion of its range of application, and the Glass Steel Tube conduit volume is large, material is heavy, be not easy to install and use, because pipeline is crisp hard, the work-ing life of breaking easily is short again; And above-mentioned pipeline when wearing cable and the cable contact surface large, friction resistance is large, cable skin damages easily, its insulating property are poor, radiating effect is poor, has been not suitable with the mat formation demand of industry development of cable.
Summary of the invention
In view of above-mentioned weak point, the object of the present invention is to provide a kind of carbon fibre rigid cable engineering pipe and preparation method thereof, this carbon fibre rigid cable engineering pipe not only its tensile strength, shock strength and flexural strength strengthens greatly, and also greatly increase work-ing life.
In order to achieve the above object, we at first are studied prescription and the preparation technology of carbon fibre rigid cable engineering pipe:
Because high density polyethylene(HDPE) has the advantages such as good impact resistance, good, the anti-anti-environmental stress cracking of winter hardiness is good, chemical stability is splendid, oil-proofness good, electrical insulating property is good, still with the major ingredient of high density polyethylene(HDPE) as this prescription.
Because alkali magnesium sulfate crystal whisker is a kind of inorganic enhancing toughening material, have intensity height, proportion little, to characteristics such as the polar solvent affinity are strong, can be used for the reinforced plastics mechanical property.In order further to increase the rigidity of cable work pipe, we select alkali magnesium sulfate crystal whisker to be used as the firm masterbatch that increases of the present invention's prescription.
In whole prescription and preparation technology thereof, alkali magnesium sulfate crystal whisker need to be used with coupling agent, and adopt alkali magnesium sulfate crystal whisker to cooperate the test that high density polyethylene(HDPE) is strengthened its mechanical property to show with coupling agent, the consumption of coupling agent and effect are not to be proportional relation, amount too much then the coupling agent surplus make on the contrary degradation, be embodied in indexs such as in plastics, making stretchings, shock resistance and descend, if measure very little, then because cladding not exclusively, effect is not remarkable.Select titanate coupling agent among the present invention, because the titanate coupling agent consumption is few, bring into play due effect for making it, it is disperseed in alkali magnesium sulfate crystal whisker equably, otherwise, do not reach coupling effect, we have just taked following technique: first titanate coupling agent is put into toluene solvant and soak, the toluene consumption just covers titanate coupling agent with the toluene liquid level and is as the criterion; And then alkali magnesium sulfate crystal whisker and the titanate coupling agent that soaks toluene mixed, then with heating or decompression method is removed toluene solvant, the alkali magnesium sulfate crystal whisker that obtains mixing and the mixture of titanate coupling agent.
Although having, its tensile strength of matrix material, shock strength and the flexural strength of high density polyethylene(HDPE) being carried out making after the modification by alkali magnesium sulfate crystal whisker and titanate coupling agent significantly improved, but because alkali magnesium sulfate crystal whisker itself is exactly the high strength hard brittle material, it still has following problem: the matrix material that makes, fragility is large, ageing resistance is poor, and the matrix material heat dispersion is not good etc.
We are by further research experiment, finding to add the T800 carbon fiber can effectively address the above problem, and the adding of T800 carbon fiber does not affect the aggregated structure of original matrix material, it mainly is distributed in the amorphous component of high density polyethylene(HDPE), similar to carbon black-filled crystalline polymer, when T800 carbon fiber add-on when shared mass percent is 5-12% in whole prescription, can obviously prolong the ageing-resistant time (the ageing-resistant time increases more than 20%), and can allow the mechanical property of matrix material strengthen more than 10%.And the adding carbon fibre, its thermal conduction characteristic of carbon fibre can make whole matrix material heat dispersion more excellent.
Can find out from above-mentioned prescription apolegamy, carry out a large amount of creative works by the contriver, obtain in following mass percent scope, having the carbon fibre rigid cable engineering pipe prescription of better effects:
