Abstract
The invention relates to an environment-friendly calcium-zinc composite stabilizer, which is characterized in that composite calcium stearate zinc soap, a chelating agent, a nano co-stabilizer, a lubricant and an antioxidant are taken as raw materials of the stabilizer, and the mixture ratio of the raw materials is as follows: 15 to 40 percent of the composite calcium stearate zinc soap, 14 to 20 percent of the chelating agent, 28 to 40 percent of the nano co-stabilizer, 15 to 20 percent of the lubricant, and 3 to 5 percent of the antioxidant. A composite calcium-zinc organic substance is formed by reaction of a nano organic auxiliary thermal stabilizer, an organic substance with chelating function, and calcium-zinc ions. The environment-friendly calcium-zinc composite stabilizer has strong commonality, quick plasticizing speed, smooth and bright surface, is nonmigratory, ageing-resistant and not tarnishable, and can be applied to various white PVC products.
Description
Technical field
The present invention relates to stablizer, particularly be a kind of environment-friendly calcium-zinc compound stabilizer.
Background technology
The thermo-stabilizer principal item of using is lead salts stablizer, organic tin stablizer, metallic soap class stablizer etc. at present.Because the lead salts stablizer has bigger superiority in stability and aspect such as cost, all is the first-selection of PVC goods thermo-stabilizer therefore all the time, during present domestic PVC processes mostly with lead salt as stablizer.Along with the progress of society, the raising of people's living standard, health requirements, and the enhancing of global environmental consciousness, Lead contamination is subjected to people's attention day by day, and a lot of fields have come into effect prohibits plumbous scheme.A large amount of facts show, plumbous, cadmium compounds is to the significant damage of HUMAN HEALTH with to the serious harm of environment.Use heavy metal stabilizer also to cause the concern that people are increasing in the PVC goods, the PVC-U goods are prohibited lead also becomes trend of the times.
Present domestic calcium-zinc composite stabilizing agent major part all is liquid, is applicable to production such as ward off glue, impregnation, extrude to be used for goods such as toy, gloves, micelle.Traditional solid calcium zinc composite stabilizer, the processing request of the inaccessible PVC of its thermal stability, especially for the hard PVC goods, the course of processing initial coloration occurs easily and reddens.
Summary of the invention
In order to overcome above-mentioned technical defective, the invention provides a kind of environment-friendly calcium-zinc compound stabilizer.
To achieve these goals, the present invention adopts following technical scheme:
A kind of environment-friendly calcium-zinc compound stabilizer, its raw material are compound calcium stearate zinc soap, sequestrant, nanometer co-stabilizer, lubricant, oxidation inhibitor.Its proportioning is: compound calcium stearate zinc soap is 15-40%, sequestrant 14 ~ 20%, and nanometer co-stabilizer 28 ~ 40, lubricant 15 ~ 20, oxidation inhibitor are 3 ~ 5%.
Above-mentioned compound calcium stearate zinc soap is compound by calcium stearate, Zinic stearas.
The preparation method of environment-friendly calcium-zinc compound stabilizer is: add sequestrant, nanometer co-stabilizer, lubricant, oxidation inhibitor in compound calcium stearate, zinc soap, temperature is 130-140 ℃ of heating 5-8 hour in reactor.
Of the present inventionly utilize nano level organic auxiliary heat stabilizer, the organism and the reaction of calcium zine ion that have chelating function form calcium zinc compound organic matter, highly versatile, it is fast to have plasticizing rate, and any surface finish is not moved, ageing-resistant, not easy to change, can be applicable to various white PVC goods.
