Abstract
The invention is a technological method for modifying the form of submicron (dozens of nm-dozens of mum) micropowder of polyvinyl chloride powder raw materials, the method has low cost and high efficiency, the activity of the polyvinyl chloride micropowder material can be greatly enhanced after modification, the performance of polyvinyl chloride application can be improved in many aspects, and good economic benefits can be generated. The method can be further applied to the modification of the high molecular material submicron powder. Adding 10% ethanol as grinding aid and 2.5% 301 stabilizer into polyvinyl chloride powder raw material, ball milling with an attritor mill at 300r/min for 120min at a temperature of less than 45 deg.C to obtain material with particle size of 20-50 μm, shape changed from spherical to coiled and porous, and collecting.
Description
One, technical field
The invention belongs to high molecular polymer submicron powder modification field, particularly polyvinyl chloride polymer submicron-scale micro mist form modified technique.
Two, background technology
The present invention is with common polyvinyl chloride raw material production submicron powder of modified polyvinyl chloride, and at home, outer production field still belongs to blank, nearly one, two year research field was carried out some and explored, but also do not have practical, effective product processes.
Three, summary of the invention
The objective of the invention is provides a kind of submicron powder of modified polyvinyl chloride at the deficiencies in the prior art, and it has low cost, high-level efficiency, practicality, produces submicron powder of modified polyvinyl chloride.And further be applied to the modification of other macromolecular material submicron powders, as polypropylene, polyethylene or polystyrene.
Purpose of the present invention is realized by following technical scheme.
The polyvinyl chloride powder raw material is packed in the modified version cooled vertical ball mill, and ethanol grinding aid solvent and 301 stablizers of adding 5-15%, material ratio is 13-20: 1, rotational speed of ball-mill 400-1000 rev/min, ball milling temperature＜45 ℃, ball milling diameter 3-16mm, obtain mean particle size 20-40um through 90-180 minute ball milling, form has complicated leaf roll shape, vesicular, the submicron powder of modified polyvinyl chloride of fractal characteristic through the further classification of air classifier or pulverize, grind, can improve its performance as again.
The present invention obtains submicron powder of modified polyvinyl chloride, its surface energy increases, surfactivity strengthens, and granularity attenuates, and surface-area increases, polymer particles exposes, glass temperature reduces, and the resin major ingredient is combined with other auxiliary agent is better, and have multiple specific performance, the use properties of polyvinyl chloride is improved greatly, and range of application is more extensive.
Four, embodiment
Embodiment one:
Powdered polyvinyl chloride (PVC) RESINS is packed in the cooled vertical ball mill, and add ethanol and 301 stablizers, add-on is 8%, material ratio is 15: 1,700 rev/mins of rotational speed of ball-mill, ball milling temperature＜40 ℃, the average 8mm of ball milling diameter, obtains D at 150 minutes ball milling time
90=48um, mean particle size=26um, form presents complicated leaf roll shape and fractal characteristic.
Claims (2)
1, the submicron powder of modified polyvinyl chloride production technique, must add the ethanol of 5%-15% in it is characterized in that producing as grinding aid, with adding 301 stablizers, through ball mill grinding and air classifier and pulverizer classification, pulverize, its technical process is: add the ethanol of 5%-15% and add 301 stablizers in polyvinyl chloride powder, and carry out ball milling with the cooled vertical ball mill, 90-180 minute ball milling time, rotational speed of ball-mill 400-1000 rev/min, ball milling temperature＜45 ℃, material ratio is 10-20: 1, and ball mill uses ball radius to be 3-16mm, obtains micro mist through air classification or further classification of micronizer mill and pulverizing through ball milling, modification.
2,, it is characterized in that described polyvinyl chloride also can be polypropylene, polyethylene or polystyrene according to the described submicron powder of modified polyvinyl chloride production technique of claim 1.
