Abstract
Wear-resisting toughening PVC tubing and the preparation method that rare-earth coupling agent activation vermiculite is modified are added the invention discloses a kind of, the present invention is added in raw material using the vermiculite that rare-earth coupling agent is activated as filler, and addition is few, cheap；Vermiculite is handled by rare-earth coupling agent, rare-earth coupling agent can not only play coupled action, also because of the unique outer shell structure of rare earth element, stronger integument can be formed on vermiculite power surface, formed by shell of rare earth compounding, vermiculite granule for core inorganic rigid particle, there is stronger toughening modifying effect to PVC, simultaneously, vermiculite is handled into the interface bond strength not only increased with matrix resin by organic modification, slabbing structure is easily peeled off in friction process simultaneously, the abrasion resistance of PVC can be effectively improved.
Description
Technical field
The present invention relates to PVC production field, and in particular to it is resistance to that a kind of addition rare-earth coupling agent activation vermiculite is modified
Grind toughening PVC tubing and preparation method.
Background technology
One of product as development in science and technology, PVC in daily life it is striking can and, because it has corrosion resistance
By force, intensity it is high, rigidity it is good the features such as and be widely used in the technical fields such as feedwater, construction drainage, blowdown, chemical industry, such as with PVC
The various water supply and sewerage pipelines that material is made.
But the wearability of the material of current common PVC tubing is poor, poor toughness, therefore service life is short, it is not suitable with severe
Environment is used, and has the PVC for adding wear-resistant component in the prior art, but abrasion resistant effect and toughness reinforcing high-temperature resistant result are poor, moreover,
Because the development of current PVC pipeline is in high-speed development period, industry production capacity is constantly expanded, and many medium-sized and small enterprises are to seize market,
Cost is reduced, it is largely calcium carbonate filled etc. in formula, adulterate, have impact on the image of the whole industry of PVC pipeline, direct shadow
The PVC market shares have been rung, the loss of the PVC market shares is accelerated.
The content of the invention
It is an object of the invention to provide it is a kind of add rare-earth coupling agent activation vermiculite be modified wear-resisting toughening PVC tubing and
Preparation method, to overcome the deficiencies in the prior art.
The object of the present invention is achieved like this：
It is a kind of to add the wear-resisting toughening PVC tubing that rare-earth coupling agent activation vermiculite is modified, it is characterised in that described PVC
Including polyvinyl chloride resin, filler, stabilizer and plasticiser；The filler is that rare-earth coupling agent activates vermiculite, and the stabilizer is calcium zinc
Composite thermal stabilizer, the plasticiser is haloflex.
Relative to the polyvinyl chloride resin of 100 parts by weight, the filler is 8-10 parts, and stabilizer is 4-6 parts, plasticiser is
15-20 parts.
The preparation method of described rare-earth coupling agent activation vermiculite is：
（1）Vermiculite is placed in 110 DEG C of baking ovens and dried 2-3 hours, grinding at room temperature is cooled to and crosses 200-300 mesh sieves and obtain vermiculite power；
（2）Vermiculite power is placed in high-speed kneading machine, controls rotating speed to stir 20-30min for 600r/min, treats that temperature rises to 100-
110 DEG C, keeping temperature is constant, adds the rare-earth coupling agent of 1/2 amount, controls rotating speed for 800r/min, high-speed stirred 10-15min,
The rare-earth coupling agent for adding remaining 1/2 amount continues high-speed stirred 10-15min, discharging.
The addition of described rare-earth coupling agent is the 2-3wt.% of vermiculite consumption.
The preparation method for the wear-resisting toughening PVC tubing that a kind of described addition rare-earth coupling agent activation vermiculite is modified, it is special
Levy and be, comprise the following steps：
（1）Polyvinyl chloride resin, filler, stabilizer and plasticiser are prepared by weight percentage；
（2）The polyvinyl chloride resin prepared is put into homogenizer, when being warming up to 60-70 DEG C, plasticiser is added and continues to stir
100-110 DEG C is reached to temperature of charge, insulation adds the filler prepared, stabilizer and continues constant temperature stirring 10-15min；
（3）By step（2）Material is put into cold puddling in low speed mixer and mixed, cooling 45-50 DEG C when, discharging；
（4）By step（3）Material delivers to extrusion molding in double screw extruder and obtains tubing, double screw extruder processing temperature scope
For 150-190 DEG C, screw speed is 500-550rpm.
The present invention has following beneficial effect：The vermiculite of the invention activated using rare-earth coupling agent is added to raw material as filler
In, addition is few, cheap；Vermiculite is handled by rare-earth coupling agent, and rare-earth coupling agent can not only play coupled action, and also because
The unique outer shell structure of rare earth element, can form stronger integument on vermiculite power surface, be formed with rare earth compounding
For the inorganic rigid particle that shell, vermiculite granule are core, there is stronger toughening modifying effect to PVC, meanwhile, vermiculite is passed through
Organic modification processing not only increases the interface bond strength with matrix resin, while being easily peeled off in friction process in flakes
Shape structure, can effectively improve the abrasion resistance of PVC.
