The tube material comprises, by weight, 60-70 parts of polypropylene, 13-16 parts of di-n-octyl tin octyl thioglycolate, 0.5-0.8 parts of polyethylene wax, 0.4-0.7 parts of calcium rosinate, 0.2-0.5 parts of PbSt, 2-3 parts of a pigment, 4-8 parts of glass fibers, 5-7 parts of ethylene propylene rubber, and 2-4 parts of a liquid Ba-Zn composite stabilizer. The tube material has the advantages of low cost, improved ageing resistance, improved strength, improved impact resistance, and stress resistance.

Description

A kind of proof stress gas piping tubing
Technical field
The present invention relates to tubing field, particularly belong to a kind of proof stress gas piping tubing.
Background technology
The flexible pipe of PVC tubing is inexpensive, it is to generally acknowledge it is also to apply most outdoor pipe materials at present, but there are some defects in the flexible pipe that existing gas piping tubing is made, such as expose to the weather for a long time, aging than very fast, overcoming the way of this defect at present is to add antioxidant with UV absorbent, but the material added is costly, causes PVC flexible pipe production cost higher.
Summary of the invention
It is an object of the invention to provide a kind of proof stress gas piping tubing, with low cost, aging resistance and intensity to improve with erosion-resisting characteristics, there is the characteristic of proof stress simultaneously.
Technical scheme is as follows:
A kind of proof stress gas piping tubing, is made up of the raw material of following weight portion: polypropylene 60-70 part, dioctyltin thioglycol monooctyl ester 13-16 part, Tissuemat E 0.5-0.8 part, rosin acid calcium 0.4-0.7 part, PbSt 0.2-0.5 part, pigment 2-3 part, glass fibre 4-8 part, EP rubbers 5-7 part, liquid B a-Zn complex stabilizer 2-4 part；The concrete preparation technology of this tubing is: first the raw material of above-mentioned weight portion is put into mixer stirring, is then heated to 85～95 DEG C；Stirring 40-50min, 30-35min is stirred after being warmed to 125～145 DEG C again, 60-70 DEG C of discharging it is cooled to after stirring, again after injection moulding, briquetting pressure uses 2-2.5MPa, maintenance humidity is maintained at 80-90%, and curing temperature is 30-35 DEG C, and last moulded products carries out Quick cross-linking in boiling water and reacted.
A kind of proof stress gas piping tubing, is made up of the raw material of following weight portion: polypropylene 65 parts, dioctyltin thioglycol monooctyl ester 14.5 parts, Tissuemat E 0.65 part, rosin acid calcium 0.55 part, PbSt 0.35 part, pigment 2.5 parts, glass fibre 6 parts, 6 parts of EP rubbers, liquid B a-Zn complex stabilizer 3 parts.
The advantage of anti-electromagnetic-radiation cable formulating of recipe for pipes of the present invention is: rosin acid calcium, PbSt, not only can be greatly improved pipe performance, and become ratio relatively low, applicable popularization and application compared with prior art, the feature that the gas piping tubing that inventive formulation prepares has high intensity and high tenacity is laid equal stress on, strong shock resistance, and product component is cheap, the market competitiveness, aging resistance and intensity are improved with erosion-resisting characteristics, proof stress function admirable simultaneously.
Detailed description of the invention
A kind of proof stress gas piping tubing, is made up of the raw material of following weight portion: polypropylene 65 parts, dioctyltin thioglycol monooctyl ester 14.5 parts, Tissuemat E 0.65 part, rosin acid calcium 0.55 part, PbSt 0.35 part, pigment 2.5 parts, glass fibre 6 parts, 6 parts of EP rubbers, liquid B a-Zn complex stabilizer 3 parts；The concrete preparation technology of this tubing is: first the raw material of above-mentioned weight portion is put into mixer stirring, is then heated to 90 DEG C；Stirring 45min, then stir 32min after being warmed to 135 DEG C, it is cooled to 65 DEG C of dischargings after stirring, again after injection moulding, briquetting pressure uses 2.2MPa, and maintenance humidity is maintained at 85%, curing temperature is 32 DEG C, and last moulded products carries out Quick cross-linking in boiling water and reacted.
Stress gas piping drawing pipe intensity of the present invention and notch strength increase more than 1 times than original tubing, and the 95% of elongation at break raising, fusion time decreases 150S, it is adaptable to proof stress gas piping tubing.
