Description
Technical field
The present invention relates to the processing method of Nano material of drainpipe, particularly relate to the processing method of PVC-U Nano material of drainpipe, belong to the materials for construction field, be mainly used in the building or bury the ground draining.
Background technology
The PVC-U drainage pipe that is used in the building or buries the ground draining will satisfy user demand, has both needed to possess certain intensity, and certain rigid is arranged again, and promptly product detects needs by falling weight impact test and tensile strength test.Existing general PVC-U drainage pipe still exists the impact resistance deficiency, for the impact resistance (promptly improving the toughness of product) that improves the PVC-U product, common way is that the rubber elastomer of the CPE, the MBS that add different proportion in the product composition, ACR and so on carries out modification.But rubber elastomer is when the toughness that increases the PVC-U drainage pipe makes it to reach falling weight impact test, but is to be cost with the rigidity that reduces (sacrifice) PVC-U drainage pipe.The rigidity one of PVC-U drainage pipe reduces, and causes hot strength can not satisfy test requirements document.On the other hand, because the price of the rubber elastomer of CPE, MBS, ACR and so on has always increased cost all than the PVC height with their modified PVCs-U drainage pipe.
Summary of the invention
The objective of the invention is provides a kind of drop impact performance and hot strength to improve in order to overcome the shortcoming that prior art exists, and the processing method of the Nano material of drainpipe of product cost reduction.
The technical scheme of the processing method of Nano material of drainpipe of the present invention is:
1. mix: each combination raw materials is added in the thermal agitation machine mix, material produces heat and heats up cold mixing discharging then through agitating friction;
2. extrude: the compound after stirring drops into conical double screw extruder, by the extrusion die extruding pipe material;
3. typing: extruding pipe material adopts calibration sleeve behind the vacuum cooling tank cooling and shaping, continues to be cooled to 30 ℃～50 ℃ at the water-cooled case.
4. cut, test: the length cutting on demand of cooled tubing, detection;
The ratio that it is characterized in that described mixed material is: by weight proportion, get 100 parts of polyvinyl chloride resins, 5～10 parts of nano-calcium carbonates, 10～15 parts of precipitated calcium carbonates, compound plumbous 2.4～2.6 parts, 0.6～1.0 part of stearic acid, 1～2 part of titanium dioxide, 0～4 part of haloflex.The complex lead salt that its described compound lead is lubricant+lead salt, its described mixing are to add thermal agitation machine high speed by material rate to mix, and its described high-speed mixing is 2500 rev/mins of left and right sides thermal agitations.Put to its thermal agitation high-speed mixing time be 7-9 minute.Material is through friction generates heat and heat up, and temperature reaches back discharging more than 130 ℃, cold mixer cool to 45 ℃ with bottom discharge.
The physical property of the PVC-U Nano material of drainpipe of the technical program satisfies related standard requirements, and the inside and outside any surface finish of tubing, smooth, indefectible, tensile yield strength 〉=41Mpa, elongation at break 〉=120%, 0 ℃ of drop impact, TIR≤10%, vicat softening temperature 〉=83 ℃, vertical shrinkage factor≤5%, carrene immersion test, 15 ℃, 30min, specimen surface does not have corrosion.
The processing method of Nano material of drainpipe of the present invention, its described cold stirring are at a slow speed or add the cooling water stirring.
The specific embodiment
The invention discloses a kind of processing method of Nano material of drainpipe, processing steps is divided into:
1. the first step at first is to mix: each combination raw materials is proportionally added in the thermal agitation machine mix, material produces heat and heats up cold mixing discharging then through agitating friction;
2. second step was to extrude: the compound after stirring drops into the extruder hopper, and by being metered into conical double screw extruder, control temperature material is pressed and extruded velocity, by the extrusion die extruding pipe material;
3. the 3rd step was typing: extruding pipe material adopts calibration sleeve behind the vacuum cooling tank cooling and shaping, continue the water-cooled case be cooled to 40 ℃ upper and lower, as 30 ℃～50 ℃.
4. the 4th step was cutting, test: cooled tubing length lettering on demand cuts the back, detects qualified warehouse-in packing.
Its major technology is characterised in that described mixed material is: nano-calcium carbonate, polyvinyl chloride resin, stabilizing agent, lubricant and filler.The ratio of its mixed material is: by weight proportion, get 100 parts of polyvinyl chloride resins, 5～10 parts of nano-calcium carbonates, 10～15 parts of precipitated calcium carbonates, compound plumbous 2.4～2.6 parts, 0.6～1.0 part of stearic acid, 1～2 part of titanium dioxide, 0～4 part of haloflex.Polyvinyl chloride resin is primary raw material, and nano-calcium carbonate is material modified, and compound lead is stabilizing agent and lubricating auxiliary agent, and titanium dioxide is a colorant, and precipitated calcium carbonate is a filler.The complex lead salt that its described compound lead is lubricant+lead salt, market is on sale.Its described mixing is to join in the raw material weight ratio to carry out high-speed mixing in the thermal agitation machine, and material heats up through stirring that friction generates heat mutually, and temperature reaches back discharging more than 130 ℃, puts to cold mixer cooling and stirring and is cooled to 45 ℃ with bottom discharge.Its described high-speed mixing is the thermal agitation about 2500 rev/mins.Its thermal agitation high-speed mixing time is 7-9 minute, is generally about 8 minutes.Its described cold stirring is to stir at a slow speed or add cooling water to stir.And colorant is arranged in mixed material, as required, make the shades of colour product.
