Abstract
The invention belongs to the field of chemical preparations, and discloses a stabilizer for preparing a PVC (polyvinyl chloride) material. Solvent oil is not contained in raw materials, so that the transportation storage safety is improved. According to the technical scheme of preparing oil-phase liquid zinc and then emulsifying, the emulsion type liquid zinc stabilizer is prepared from the following raw materials in parts by weight: 300 parts of isocaprylic acid, 85 parts of zinc oxide, 120 parts of 10# white oil, 280 parts of dioctyl phthalate, 500 parts of water, 8 parts of an emulsion OP-10, and 6 parts of a B-72 dispersing agent.
Description
Technical field
The invention belongs to chemicals field, is a kind of for the preparation of PVC(polyvinyl chloride) stablizer of material.
Background technology
Existing liquid zinc PVC heat stabilizer oil phase Technical comparing is ripe, but there is solvent oil in raw material, and production cost is high, and product is inflammable, explosive, and storage request is high.
Summary of the invention
The object of this invention is to provide a kind of emulsion-type liquid zinc stabilizer, in raw material, no longer include solvent oil, improve the security that transport stores.
The present invention takes the technical scheme first preparing oil phase liquid zinc reemulsification.
Raw material is with parts by weight: isocaprylic acid: 300 parts, zinc oxide: 85 parts, and 10
#white oil: 120 parts, dibutyl ester: 280 parts, water: 500 parts, emulsifier op-10: 8 parts, B-72 dispersion agent: 6 parts.
Production stage:
1, when reactor inner bag is warming up to 40 DEG C, in still, add isocaprylic acid, then open stirrer, continue to heat up;
2, when reactor inner bag temperature reaches 60 DEG C, pour zinc oxide into reactor, continue to heat up;
3, when reactor inner bag temperature rises to 80 DEG C, with mateiral pump suction dibutyl ester;
4, salt water for cooling is opened, when reactor inner bag temperature is down to 60 DEG C, with mateiral pump suction 10
#white oil;
5, after all material finish, continue cooling and stir, within about 10 minutes, stop stirrer, obtain oil phase liquid zinc;
6, add water and B-72 dispersion agent in emulsifying kettle, open emulsification pump and carry out emulsification, the time is 10 ~ 20 minutes;
7, add emulsifier op-10 and continue emulsification, the time is 5 ~ 10 minutes;
8, enter emulsifying kettle with mateiral pump oil pumping phase liquid zinc, continue stirring and emulsifying, the time is about 40 minutes;
9, stop emulsification pump, obtain emulsion-type liquid zinc stabilizer.
The advantage of emulsion-type liquid zinc heat stabilizer: replace solvent oil to decrease cost by water miscible liquid; Not discharge, environmental protection in production process; Water miscible liquid has disperseed oil phase liquid zinc, and the liquid zinc relatively pure oil phase liquid zinc security after emulsification wants high a lot, and water is inert solvent, nonflammable explosive.
Embodiment
one, oil phase liquid zinc preparation
1, when reactor inner bag is warming up to 40 DEG C, in still, add 300Kg isocaprylic acid, then open stirrer, heat up simultaneously.
2, when reactor inner bag temperature reaches 60 DEG C, pour 85Kg zinc oxide into reactor, and continue to heat up.
3, when reactor inner bag temperature rises to 80 DEG C, with mateiral pump suction 280Kg dibutyl ester.
4, salt water for cooling is opened, when inner bag temperature is down to 60 DEG C, with mateiral pump suction 120Kg white oil.
5, after all material finish, continue cooling and stir, after about 10 minutes, can stirrer be stopped.
Two,
emulsification
1, in emulsifying kettle, drop into 500Kg water, then add 6Kg B-72 dispersion agent, open emulsification pump and carry out emulsification, the time is 10 ~ 20 minutes.
2, add 8Kg emulsifier op-10 and continue emulsification, the time is 5 ~ 10 minutes.When envrionment temperature is lower than 0 DEG C, add 100Kg methyl alcohol.
3, take out 785Kg oil phase liquid zinc with mateiral pump and enter emulsifying kettle, continue stirring and emulsifying, the time is about 40 minutes.
4, stop emulsification pump, discharging is freighted.Be stored in shady and cool dry place.Normal temperature, prevent naked light.
three, physical and chemical index
| Index name | Index |

| Proportion, >= | 0.95 |
The present invention can improve the thermal stability of resin effectively, reduces and prevents the generation with the unstable structure such as side chain, chlorallylene on main chain, preventing from main chain producing conjugated polyene sequence, avoids producing small molecule structure, improves the thermal ageing whiteness of polyvinyl chloride resin.Reduce the resistance of phase interface and intermolecular selectivity magnetism, also owing to reducing the surface tension of monomer phase, favourable generation particle diameter be less, the PVC particle of short texture, improve the desorption rate of PVC.In polymeric kettle blending process, the present invention is once dropped in polymeric kettle with other auxiliary agents with being polymerized, stirs.
