Shandong composite stabilizer _ Extension-technology (Certified) _ composite stabilizer

Calcium zinc composite stabilizer Formula 1: The crude wool acid at 40-100 ℃ melted. 2: 50-100 ℃ sodium hydroxide in aqueous ethanol dissolved in ethanol - aqueous ethanol concentration of 80% -85% by volume of ethanol - water mixture. 3: Step 1 molten wool acid was gradually added to the solution of step 2 composite stabilizer, stirring saponification reaction 1-4h at 50-100 ℃, reaction principle RCOOH + NaOH → RCOONa + H2O, which is wool RCOOH acid. 4: The hot reaction solution to adjust the PH value is 7-9, and then cooled to 40-70 ℃ barium lead compound stabilizer, adding a certain volume of the first [reaction solution; water = (1: 9) to (1: 4), volume] of warm water, then successively added calcium chloride and zinc sulfate seven water, the reaction was purified by suction filtration after 1-4h Shandong composite stabilizer, an alcohol wash, washing, drying and pulverizing after the finished product. The basic components include: (1) a barium salt - can be alkylphenols, barium 2-ethylhexanoate, barium laurate (powder compound used), benzoic acid and substituted benzoic acid barium, barium neodecanoate . Accounting for 6-7% of barium salt complex, namely cadmium salt ratio is about 2: 1-32 (metal record, by weight pvc composite stabilizer, the same below). (2) cadmium salts - may be 2-ethylhexanoate cadmium, cadmium lauric acid, oleic acid, cadmium, phenyl substituted benzoic acid and cadmium, cadmium naphthenic acid, neodecanoic acid cadmium. Cadmium salt accounts for about 3-4% in the complex. (3) zinc - may be a 2-ethylhexyl zinc laurate (powder compound used), zinc naphthenate neodecanoate, benzoic acid and substituted benzoic acid zinc. Zinc accounted for 0.5% in the complex. (4) aliphatic phosphite - may be a triphenyl phosphite, a phosphite, diphenyl octyl phosphite, diphenyl decyl an acrylate, tris (nonylphenyl) and the like. Phosphite accounting for 15-20% (by weight) in the complex, as chelating agents can be used as an auxiliary acid absorber stabilizer of PVC. It has been speculated that they can form a complex in the degradation reaction sites and reduce the activity of the reaction sites, but also to capture HCL having a catalytic activity to avoid the removal of the HCL reaction. Epoxide industry often associated with calcium zinc stabilizer and have played a certain synergy In short, composite heat stabilizer is conducive scale production, the development of lead salt thermal stabilizer provides a new direction. An important indicator of composite lead salt stabilizer is lead content, lead content of lead salt composite stabilizer's current production is generally 20% to 60%; the amount of PVC plastic doors and windows profile production of 3.5-6 parts Shandong composite stabilizer _ Extension-technology (Certified) _ composite stabilizer is provided by Qingdao Extension-Technology Limited.
