Abstract
The invention discloses a high-toughness PVC flexible pipe formula which is prepared from the following raw materials in parts by weight: 25-45 parts of polyvinyl chloride resin, 7-11 parts of rubber powder, 4-8 parts of 1-hydroxyethyl-2-oil-based imidazoline, 5-10 parts of zinc oxide, 5-10 parts of polyvinyl butyral ester, 6-9 parts of powdery butyronitrile, 6-9 parts of precipitated barium sulfate, 14-18 parts of triethyl citrate, 3-7 parts of benzotriazole, 15-25 parts of calcium stearate, 4-7 parts of phthalic anhydride, 6-10 parts of silicon carbide whisker, 3-6 parts of calcium aluminate and 4-8 parts of citric acid. The high-toughness PVC flexible pipe formula disclosed by the invention has the advantages of low cost, good ageing resistant effect, good low temperature resistant property, flexibility and antistatic property, high toughness, high elongation rate, good ageing resistant effect and high impact strength and tensile strength and can effectively postpone the material degradation, reduce the bending degree of pipes and prolong the service life.
Description
Technical field
The present invention relates to building material technical field, be specifically related to a kind of high tenacity PVC flexible pipe formula.
Background technology
PVC flexible pipe is good and cheap, it is the good outdoor water pipe of generally acknowledging at present, but also Shortcomings part of existing PVC flexible pipe: PVC flexible pipe is exposed to the weather for a long time out of doors, very easily causes agingly, and macromolecular material aging is mainly to attack by free radical the chain reaction that macromolecular chain causes.Generally solve by adding antioxidant and UV light absorber, antioxidant and UV light absorber are expensive, make PVC flexible pipe cost higher.Very stable under the structure normal temperature of polyvinyl chloride, insensitive to oxygen and UV-light, should be more ageing-resistant, even if but the hose of outdoor to have added after antioxidant and UV light absorber antiageing effect still not good enough.
Summary of the invention
For the deficiencies in the prior art, technical problem to be solved by this invention is, provide a kind of with low cost, antiageing effect good, resistance to low temperature, snappiness and antistatic property better, toughness is high, and elongation is large, and antiageing effect is good, normal temperature shock strength, tensile strength are high, can effectively delay material degraded, reduce the sinuousness of tubing, increase the high tenacity PVC flexible pipe formula in work-ing life.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of high tenacity PVC flexible pipe formula, raw material by following parts by weight is made: polyvinyl chloride (PVC) RESINS 25-45 part, rubber powder 7-11 part, 1-hydroxyethyl-2-oil-based imidazoline 4-8 part, zinc oxide 5-10 part, polyvinyl butyral acetal ester 5-10 part, powdered nitrile rubber 6-9 part, process white 6-9 part, triethyl citrate 14-18 part, benzotriazole 3-7 part, calcium stearate 15-25 part, Tetra hydro Phthalic anhydride 4-7 part, silicon carbide whisker 6-10 part, calcium aluminate 3-6 part, citric acid 4-8 part.
Above-mentioned high tenacity PVC flexible pipe formula, is made up of the raw material of following parts by weight: 35 parts of polyvinyl chloride (PVC) RESINS, 9 parts of rubber powders, 6 parts of 1-hydroxyethyl-2-oil-based imidazolines, 8 parts, zinc oxide, 8 parts of polyvinyl butyral acetal esters, 7 parts of powdered nitrile rubbers, 8 parts of process whites, 16 parts of triethyl citrates, 5 parts of benzotriazoles, 20 parts of calcium stearates, 5 parts of Tetra hydro Phthalic anhydrides, 8 parts of silicon carbide whiskers, 5 parts of calcium aluminates, 6 parts of citric acids.
High tenacity PVC flexible pipe formula advantage of the present invention is:
1, high tenacity PVC flexible pipe formula of the present invention, with low cost, antiageing effect good, resistance to low temperature, snappiness and antistatic property better, toughness is high, elongation is large, antiageing effect is good, and normal temperature shock strength, tensile strength are high, can effectively delay material degraded, reduce the sinuousness of tubing, increase work-ing life.
