Description
Technical field
The present invention relates to a kind of double-wall corrugated pipe production methods of PVAS alloy high strengths.
Background technology
Double-wall corrugated pipe obtains in fields such as communication cable jacket, construction drainage, municipal drainage, farmland low pressure irrigations
Extensive use.Since double-wall corrugated pipe has the techniques such as blowing, the plastic uptake on structure double-deck, that wall is thin too list and production special
Point makes it have many differences with straight wall pipe in terms of formula design and processing technology.Polyvinyl chloride resin is that one kind is noncrystalline, polarity is high
Molecularly Imprinted Polymer, softening temperature and melting temperature are higher, and pure polyvinyl chloride resin, which generally requires to be plasticized at 160~210 DEG C, to be added
Work, but when temperature reaches 120 DEG C, polyvinyl chloride resin starts thermal degradation.Moreover, Double-wall PVC bellows due to wall material it is relatively thin
(0.5~2.5mm) has plastic uptake and blow molding process in process, to avoid melt fracture, mixture from needing higher melt
Intensity, it is therefore desirable to which polyvinyl chloride resin is modified.
Invention content
The technical problem to be solved in the present invention is to provide a kind of PVAS alloy high strength double-walleds of production stage reasonable design
Ripple pipe production method.
In order to solve the above-mentioned technical problem, the present invention includes the following steps：
A, start high-speed kneading machine and its low speed is made to run, sequentially add polyvinyl chloride resin, stabilizer, processing aid, lubricant,
High-speed kneading machine adds calcium carbonate and high impact-resistant modifying agent when operating 2-3 minutes, improves the speed of service of high-speed kneading machine
And kneading temperature；
B, start cold mixing machine high-speed kneading machine is switched to low-speed running, is opened its discharge by technological requirement preset cold mixing temperature
Valve allows material to enter in cold mixing machine and is cooled to preset cold mixing temperature, then drains into vibrating screen；
C, the material after cold mixing is transferred in extruder and carries out plasticizing extrusion；
D, it is tubing that the material after plasticizing, which is transferred in molding machine and carries out compression molding, and then carrying out coding by printer beats
Print；
F, the tubing after printing is entered into bracket, leads and helps cutting machine, adjusted and cut evidence processed, measured by pipe standard length
Cutting；
G, the tubing after metering cutting is flared by pipe-expanding machine, is then put at collecting frame and is stacked.
As a further improvement on the present invention, in step, the polyvinyl chloride resin is 100 parts, and calcium carbonate is 2-25 parts, profit
Lubrication prescription is 0.1-0.8 parts, and stabilizer is 3-5 parts, and high impact-resistant modifying agent is AS or MBS, processing aid ACR, ACR 1-2
Part, high impact-resistant modifying agent is 5-8 parts.
As a further improvement on the present invention, in step, add when the temperature in high-speed kneading machine is 60 DEG C to 70 DEG C
Enter polyvinyl chloride resin, stabilizer, processing aid, lubricant, calcium carbonate and highly resistance are added when the temperature in high-speed kneading machine is 90 DEG C
Impact modifying agent.
As a further improvement on the present invention, in step：The kneading temperature is 110 DEG C to 120 DEG C；In step B
In：The cold mixing temperature is 42 DEG C to 48 DEG C
As a further improvement on the present invention, in step D：Before the material after plasticizing is transferred to molding machine, molding is opened
The vacuum pump of machine forms interbed air pressure by vacuum pump in molding machine.
Beneficial effects of the present invention：By adding processing aid, the intensity and toughness for improving composite material can be improved, is led to
Addition high impact-resistant modifying agent is crossed, composite impact intensity is promoted.The reasonable design of the production process simultaneously, the person of being conveniently operated
Rapid and convenient is efficiently produced.
Specific implementation mode
The present invention includes the following steps：
A, start high-speed kneading machine and its low speed is made to run, when the temperature in high-speed kneading machine is 60 DEG C to 70 DEG C, add successively
Enter 100 parts of polyvinyl chloride resin, 3-5 parts of stabilizer, ACR1-2 parts of processing aid, 0.1-0.8 parts of lubricant, is operated in high-speed kneading machine
Temperature in 2-3 minutes and high-speed kneading machine adds 2-25 parts of calcium carbonate and high impact-resistant modifier A S when being 90 DEG C be 5-8
Part, the speed of service and kneading temperature of high-speed kneading machine are improved, kneading temperature is 110 DEG C to 120 DEG C；
B, start cold mixing machine, by the preset cold mixing temperature of technological requirement, cold mixing temperature is 42 DEG C to 48 DEG C, and high-speed kneading machine is switched to
Low-speed running opens its blow-off valve, allows material to enter in cold mixing machine and is cooled to preset cold mixing temperature, then drains into vibrating screen；
C, the material after cold mixing is transferred in extruder and carries out plasticizing extrusion；
D, before the material after plasticizing is transferred to molding machine, the vacuum pump of molding machine is opened, by vacuum pump in molding machine
Interbed air pressure is formed, it is tubing that the material after plasticizing, which is transferred in molding machine and carries out compression molding, is then carried out by printer
Coding prints；
F, the tubing after printing is entered into bracket, leads and helps cutting machine, adjusted and cut evidence processed, measured by pipe standard length
Cutting；
G, the tubing after metering cutting is flared by pipe-expanding machine, is then put at collecting frame and is stacked.
ACR (propionic acid enester) has nucleocapsid, and shell PMMA polymer can protect stratum nucleare tissue, while be situated between as centre
Matter improves ACR and PVC compatibilities, and ACR toughening effects rely primarily on the crosslinked PBA rubber of stratum nucleare, and toughness is good.ACR shells
Component is similar to polyvinyl chloride resin structure, and the two has good compatibility, keeps ACR evenly dispersed in PVC matrix, bonding situation
Well, the intensity and toughness of composite material are greatly improved.AS (haloflex) and PVC compatibilities are preferable.AS is as elasticity
Body plays the role of intermediate medium, under stress, the primary particle of rupture and secondary can be made to form shear band, passed through
Stress concentration effect dispersion impact energy, is substantially improved composite impact intensity.Micro- buffering area of AS and the interfaces PVC, compatibility
Well, intermolecular generation interaction, improves the cohesive force between interface, AS forms physical network in the base, can be substantially
Improve fracture of composite materials elongation.Two kinds of elastomers of AS and ACR add simultaneously, fabulous with PVC compatibilities, form firm net
Network structure improves the intensity and toughness of product.
It carries out double-wall corrugated pipe through the above steps to be produced, step reasonable design can make operator quickly just
Victory is efficiently produced.Before the material after plasticizing is transferred to molding machine, the vacuum pump of molding machine is opened, vacuum pump is passed through
Interbed air pressure is formed in molding machine, can ensure the stability of bellows outside wall surface waveform shape in this way.
