Hydrotalcite for P.V.C. stabilizer and a method of thereof

Abstract

A zinc-deposited hydrotalcite for a PVC stabilizer includes: a hydrotalcite having a structure represented by the formula of Mg 4 Al 2 (OH) 12 CO 3 .3 H 2 O; and zinc deposited onto the hydrotacite crystals by using any one method of electrode-position, chloride ion deposition, and plasma deposition.

The invention claimed is: 
     
       1. A zinc-deposited hydrotalcite for a stabilizer, comprising:
 a hydrotalcite having a structure represented by the formula of Mg 4 Al 2 (OH) 12 CO 3 .3H 2 O; 
 calcium in conjunction with zinc (Zn) deposited on the hydrotalcite, wherein a weight percentage of calcium is 0.84%; and 
 a coating of 2.5% stearic acid on the hydrotalcite, the calcium and the zinc. 
 
     
     
       2. A stabilizer, comprising the zinc-deposited hydrotalcite of  claim 1  as an additive or antibacterial agent. 
     
     
       3. A resin, comprising:
 a stabilizer, comprising:
 a hydrotalcite having a structure represented by the formula of Mg 4 Al 2 (OH) 12 CO 3 .3H 2 O; 
 calcium in conjunction with zinc deposited on the hydrotalcite, wherein a weight percentage of calcium is 0.84%; and 
 a coating of 2.5% of stearic acid on the hydrotalcite, the calcium and the zinc; and polyvinyl chloride (PVC). 
 
 
     
     
       4. The resin according to  claim 3 , wherein the resin further comprises zinc stearate or calcium stearate. 
     
     
       5. A product, comprising the resin of  claim 3 . 
     
     
       6. The product of  claim 5 , being one of pipes, window frames and sheets.
