Abstract
The invention relates to a high-strength rigid polyvinyl chloride finned tube which comprises the following components by weight part: polyvinyl chloride resin: 100 of major ingredient, polyacrylate copolymer: 4-6 of plasticiser, composite lead heat stabilizer: 4-8 of stabilizer, stearic acid: 0.1-0.6 of lubricant, calcium stearate: 0.1-0.5 of stabilizer and lubricant, filling agent: 25-50 of filling materials, and calcium carbonate: 25-50 of filling materials.
Description
Technical field:
The present invention relates to rigid polyvinyl chloride finned tube, refer to a kind of high-strength rigid polyvinyl chloride finned tube especially.
Background technology:
Polychloroethylene pipes is a kind of kind of tube types that is most widely used in the existing market, and, easy construction simple, with low cost because of its processing obtains very high share of market.
China to last century the nineties begin to introduce advanced foreign technology and produce the bigbore ground draining polyvinyl chloride finned tube that buries, its cost performance with excellence has progressively replaced traditional cement pipe, steel pipes etc. are obtained good effect.
But along with the strictness of construction requirement and the requirement of some large-scale public works promote, original polyvinyl chloride finned tube anti-pressure ability can't satisfy construction requirement gradually.
Summary of the invention:
Technical problem to be solved by this invention just is to overcome deficiency of the prior art, a kind of high-strength polyvinyl chloride riffled tube is provided, the ring stiffness of this product can reach more than ten grades, surpasses eight grades of the highest rigidity of existing market, for the scope of having expanded is used in the extension of this tubing.
The invention provides a kind of high-strength polyvinyl chloride riffled tube, with listed as parts by weight, composition is:
Polyvinyl chloride (PVC) RESINS 100 major ingredients
Acrylate copolymer 4-6 softening agent
Lead salt composite thermal stabilizer 4-8 stablizer
Stearic acid 0.1-0.6 lubricant
Calcium stearate 0.1-0.5 stablizer, lubricant
Weighting agent 25-50 stopping composition
Lime carbonate 25-50 stopping composition.
Production method of the present invention adopts operational path commonly used, with the logical overheated machine of polyvinyl chloride resin and auxiliary agent mediate, cold machine stirs, plastify extrude, moulding, cutting, enlarging get final product.
The invention has the beneficial effects as follows:
By absorption, digestion, constantly test to advanced person's prescription, adjusted the type of functional agent, added novel weighting agent, material stiffness is got a promotion.Mould is transformed, made moulding product have higher compressive property.
Embodiment:
Tubing is pressed the ring stiffness grade separation, sees Table 1:
Table 1 nominal ring stiffness grade (unit: thousand Ns/square metre)
The physical and mechanical property of tubing should meet the regulation of table 2.
Press the regulation of GB/T 9647-2003.Compression speed is determined ring stiffness by the external diameter of tubing.
Table 2 tubing physical and mechanical property index.
The test impact property:
Regulation by GB/T 14152-2001 is tested.The tup radius-of-curvature of dropping hammer is 50.0mm ± 0.5mm, and shock height is 2000mm ± 10mm, and test temperature is (0 ± 1) ℃, and other test parameter sees Table 5.
Table 3 shock resistance test parameter
Specified size DN/ID | Every sample is answered the setting-out number | The quality of dropping hammer, kg |
150 | 8 | 1.0 |
225 | 14 | 2.5 |
300 | 20 | 3.2 |
400 | 20 | 3.2 |
500 | 20 | 3.2 |
600 | 20 | 3.2 |
800 | 20 | 3.2 |
1000 | 20 | 3.2 |
Observe the sample after impacting, any position is crack-free all, and the stress whitening that produces because of impacting is arranged.
