Abstract
The invention relates to a halogen-free low-smoke weather-proof corrugated pipe which comprises a black steel strip with high strength and fine corrosion resistance. End openings of the steel strip are wavy, sections of the steel strip are mutually meshed to enhance the connecting strength of the corrugated pipe, halogen-free low-smoke flame-retardant irradiation polyolefin is extruded on the periphery of the steel strip and is low-smoke, halogen-free, non-toxic, flame-retardant, resistant to high temperature and the like, and the steel strip and materials inside the steel strip are further isolated and protected. The halogen-free low-smoke weather-proof corrugated pipe has the advantages of simple structure, low manufacturing difficulty, fine corrosion resistance, high mechanical strength, high connecting strength and the like, and further has the advantages of flame resistance, low smoke, halogen-free and non-toxic property, fine weather resistance and the like by the aid of halogen-free low-smoke flame-retardant irradiation polyolefin materials, and materials inside and outside the corrugated pipe can be strongly protected and isolated under the combined action of the black steel strip and the halogen-free low-smoke flame-retardant irradiation polyolefin materials.
Description
Technical field
The present invention relates to corrugated pipe technical field, specifically the weather-proof bellows of a kind of low smoke, zero halogen.
Background technique
Along with the quickening day by day of urban infrastructure construction step, bellows is used by increasingly extensive as important infrastructure equipment, meanwhile, the quality of people to bellows and the also more and more attention of requirement of characteristic, people's living environment is day by day complicated at present, domestic sewages etc. are increasing, composition is day by day complicated, the Environmental Conditions of bellows is more severe, so people require also more and more higher to the combination property of bellows, general bellows only has corrosion-resistant, the characteristic of the minority aspects such as environmental protection or intensity height, can not meet the requirement that modern people are higher to bellows combination property.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides the weather-proof bellows of a kind of low smoke, zero halogen.
The present invention solves its technical problem and realizes by the following technical solutions:
The weather-proof bellows of a kind of low smoke, zero halogen, comprises steel band, and described steel band is that intensity is high, the black steel band of good corrosion resistance, the port undulate of steel band, and interlock mutually between steel band section and section, to increase the join strength of bellows; Described steel band periphery is extruded with halogen-free low-smoke irradiation polyolefin, and halogen-free low-smoke irradiation polyolefin has the characteristics such as low cigarette, Halogen be nontoxic, fire-retardant, high temperature resistant, and steel band and steel band materials inside are played to further insulation blocking effect.
Thickness 0.3～the 0.5mm of described steel band, the steel band that 0.3～0.5mm is thick has guaranteed the routine use requirement of bellows, has reduced cost of production, has saved resource, the unnecessary waste of having avoided blocked up steel band to cause.
The invention has the beneficial effects as follows: the present invention have simple in structure, manufacture difficulty is low, good corrosion resistance, mechanical strength are high, join strength advantages of higher; and adopt halogen-free low-smoke irradiation polyolefine material; guaranteed that bellows has fire-retardant, the advantage such as low smoke and zero halogen is nontoxic, good weatherability, the comprehensive function of steel band and halogen-free low-smoke irradiation polyolefine material can have been played very strong protection, buffer action to the material inside and outside bellows.
The characteristic that the present invention also has is:
(1) halogen-free low-smoke irradiation polyolefine material has the characteristics such as remarkable heat-resisting, low smoke, zero halogen environmental protection, UV-b radiation, there is best weather resistance, UV resistant and ozone erodibility simultaneously, and can bear wider temperature variation, can reach 25 years the service life under general condition; Halogen-free low-smoke irradiation polyolefine material has special surface property: have agent of low hygroscopicity, fungicidal properties is good, not sticky to many materials;
(2) halogen-free low-smoke irradiation polyolefine material has splendid low smoke, zero halogen and flame retardant property, PH >=4.3; Specific conductance≤10 μ S/mm; Flame retarding can reach FV-0 level, do not prolong combustion after lighting, and burning basic point is not;
(3) can pass through ozone resistance test: specimen length 20cm, places 16h in dry vessel.(2 ± 0.1) that flexuraltest coupon diameter used is the outside diameter of cable doubly, test chamber: temperature (40 ± 2) ℃, relative moisture (55 ± 5) %, ozone concentration (200 ± 50) × 10-6%, air mass flow: 0.2～0.5 times of volume of the chamber/min.Sample is placed test chamber 72h, and after test, jacket surface is without eyesight visible crack.
(4) can pass through weathering resistance/UV test: each cycle: watering 18min, xenon lamp is dried 102min, temperature (65 ± 3) ℃, relative moisture 65%, the minimum power under wavelength 300～400nm condition: (60 ± 2) W/m2.Continue to carry out flexuraltest under room temperature after 720h.Coupon diameter is 4～5 times of external diameter, and after test, jacket surface is without eyesight visible crack.
(5) can test (25 years): Cl and Br content by the thermal endurance of carrying out according to EN60216-1, EN60216-2 Arrhenius curve: HCL≤0.5%; HBr≤0.5%; F content≤0.1%;
(6) can pass through impermeability test: in bellows, pour water or cement slurry that the ratio of mud is 0.5 30 minutes without leaking, spillage.
(7) can test by tension: axial tension 5KN, corrugated pipe wall is without damage.
(8) can test by bending resistance: when 30d that bending bellows is radius of curvature by bellows tortuosity folding, bellows without leaking, spillage.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is sectional view of the present invention.
Embodiment
For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, further set forth the present invention below in conjunction with accompanying drawing.
As shown in Figure 1, the weather-proof bellows of a kind of low smoke, zero halogen, comprises steel band 1, and described steel band 1 is that intensity is high, the black steel band of good corrosion resistance, the port undulate of steel band 1, and interlock mutually between 1 section of steel band and section, to increase the join strength of bellows; Described steel band 1 periphery is extruded with halogen-free low-smoke irradiation polyolefin 2, and halogen-free low-smoke irradiation polyolefin 2 has the characteristics such as low cigarette, Halogen be nontoxic, fire-retardant, high temperature resistant, and steel band 1 and steel band 1 materials inside are played to further insulation blocking effect.
Thickness 0.3～the 0.5mm of described steel band 1, the steel band 1 that 0.3～0.5mm is thick has guaranteed the routine use requirement of bellows, has reduced cost of production, has saved resource, the unnecessary waste of having avoided blocked up steel band 1 to cause.
