Abstract
The invention relates to a preparation method of environment-friendly calcium-zinc compound heat stabilizer for PVC (polyvinyl chloride). The environment-friendly calcium-zinc compound heat stabilizer for PVC is mainly made from zinc stearate, calcium stearate and di-n-octylo-phthalate with co-stabilizer, lubricant and the like. The environment-friendly calcium-zinc compound heat stabilizer for PVC has high heat stability and processibility and is environment-friendly, low in cost, high in plasticity in processing of the PVC and capable of lowering balancing torque, and is widely applicable.
Description
Technical field
The present invention relates to the preparation method that a kind of PVC uses the environmental protection Ca-Zn composite heat stabilizer.
Background technology
Igelite has from the advantage such as putting out, fire-retardant, wear-resisting, intensity is higher, electrical insulating property and chemical stability are better, and cheap, use very extensive, but the PVC less stable, add need add some amount man-hour thermo-stabilizer to suppress its degraded.The thermo-stabilizer that is used at present PVC mainly contains lead salt, metal soap, organic tin, rare earth class and composite thermal stabilizer.
Lead salt stabilizer is to develop to reach the earliest preferably PVC thermo-stabilizer of stabilising effect, but long-term the contact with products containing lead can be caused contact stain(ing) and poisoning.So the use of plumbous type thermal stabilizing agent is subject to strict restriction.
In the face of the environmental regulation of increasingly stringent, " green " plastics have become the developing direction of 21 century plastics industry, multi-functional, Composite, efficient, low toxicity or the nontoxic development trend that has become the PVC thermo-stabilizer.And a series of organic PVC thermo-stabilizer that takes the lead in using at European ﹠ American Market, its performance has reached the level of metal soap thermal stabilizers, has eliminated the toxicity hidden danger of heavy metal from basic L, has represented the developing direction of PVC thermo-stabilizer.
Non-toxic heat stabilizer at present commonly used has organic tin and metal soap thermal stabilizers.The organic tin cost is high, in use uses wideless.Metal soap lower cost, especially calcium, zinc soap class asepsis environment-protecting are used more in stablizer, but because the independent result of use of metallic soap is poor, so need to carry out this zinc soap class compositely, obtain preferably thermo-stabilizer, better must be used in the PVC manufacture field.
Summary of the invention
The purpose of this invention is to provide a kind of Ca-Zn composite heat stabilizer composition, this one package stabilizer environment-protecting asepsis can significantly provide the thermostability of PVC, and goods has the preferably transparency and slickness.
The technical solution used in the present invention is:
Zinic stearas: 10-18 part;
Calcium stearate: 8-25 part;
Softening agent: 25-35 part;
Oxidation inhibitor: 1-3 part;
Activated Calcium carbonate: 0-40 part;
Lubricant: 5-10 part;
Auxiliary addition agent Magnesium Stearate: 2-5 part;
Auxiliary addition agent aluminium hydroxide: 3-5 part;
Described softening agent is one of following: o-phthalic acid dibutyl ester, diisononyl phthalate, Di Iso Decyl Phthalate;
Described oxidation inhibitor is any one in oxidation inhibitor 689, antioxidant 264, the antioxidant 1010;
Described lubricant is wherein a kind of in solid paraffin and the polyvinyl chloride wax;
Described other auxiliary addition agents are Magnesium Stearate and aluminium hydroxide.
The invention still further relates to the preparation method that a kind of PVC uses the environmental protection calcium-zinc composite stabilizing agent, described method comprises the steps: according to the prescription consumption, softening agent is added in the flask, slowly be warming up to 60-70 ℃, treat temperature-stable, add Zinic stearas, calcium stearate, oxidation inhibitor, activated Calcium carbonate, auxiliary addition agent, the lubricant of formula ratio, with material fully stir, melting, reaction is 1 hour under 60-70 ℃ temperature, and cooling obtains calcium-zinc composite stabilizing agent.
Zinc composite stabilizer of the present invention and preparation method thereof advantage is mainly reflected in: can mix so that solid, liquid starting material fully disperse in the prescription, improved the synergy of stock yard, and can the more effective thermal stability that improves the PVC goods.
