Abstract
The invention discloses a high-stability PVC (polyvinyl chloride) material and a preparation method thereof. The material is prepared from components in parts by weight as follows: 100 parts of PVC, 0.1-0.2 parts of 2-mercaptobenzothiazole, 0.2-0.3 parts of a light stabilizer, 60 parts of a plasticizer, 0.2-0.3 parts of a sulfurizing reagent and 1-1.4 parts of a lubricating agent. The special stabilizer is grafted to a PVC macromolecular link through modification, and the heat stability of PVC is remarkably improved.
Description
Technical field
The invention belongs to chemical technology field, relate to a kind of high stable pvc material and preparation method thereof.
Background technology
Polyvinyl chloride (PVC) is the good general-purpose plastics of a kind of combination property, has excellent processing characteristics, good machineryMechanical property. Particularly add after a large amount of plasticizer, can obtain the polyvinyl chloride elastomer of rubber like, combination propertyGood, but unstable under hot conditions, easily decompose not environmental protection, poor stability.
Therefore, need at present a kind of high stable pvc material badly, to meet people to the diversified demand of plastic products.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point a kind of high stable pvc material is provided.
Another object of the present invention is to provide the preparation method of this high stable pvc material.
The object of the invention is to realize in the following manner:
A kind of high stable pvc material, this material is to be made up of the component of following weight portion:
Above-mentioned light stabilizer is two-2-ethylhexyl sulfo-sodium succinate.
Described plasticizer is dioctyl phthalate.
Described vulcanizing agent is cumyl peroxide.
Above-mentioned lubricant is preferably paraffin.
The preparation method of above-mentioned high stable pvc material comprises the following steps:
PVC, 2-mercaptobenzothiazole, plasticizer, lubricant, light stabilizer are stirred to 10-15 minute in high mixer,The double screw extruder (manufacture of Nanjing Cheng Meng Chemical Equipment Co., Ltd.) of 1:40 in draw ratio by the powder being stirredIn the first hopper, add, in the second hopper, add vulcanizing agent. Screw speed 50-90 rev/min, the second hopper and the first hopperDistance be 16:40 with the ratio of screw rod overall length, double screw extruder temperature arranges as shown in the table:
| Region | Machine barrel 1st district | Machine barrel 2nd district | Machine barrel 3rd district | Machine barrel 4th district | Machine barrel 5th district |
| Temperature | 100℃ | 120℃ | 140℃ | 150℃ | 160℃ |
| Machine barrel 6th district | Machine barrel 7th district | Machine barrel 8th district | Machine barrel 9th district | Machine barrel 10th district | Head |
| 160℃ | 160℃ | 160℃ | 150℃ | 140℃ | 180℃ |
Beneficial effect of the present invention compared with the prior art:
The present invention is by modification, extraordinary stabilizing agent sulfur-based compound is grafted to PVC macromolecular chain and connects, and has improved PVCHeat endurance. In the situation that heat endurance increases, other performances of material of the present invention are unaffected.
