3. In PVC soft products, the recommended dosage of aluminum pentaerythritol is 3.86 Phr.
4. In PVC hard products, the recommended dosage of aluminum pentaerythritol is 3.6 Phr.
5. Aluminum pentaerythritol and zinc stearate have a very good synergistic effect. The recommended ratio is: 3:1
6. Aluminum pentaerythritol and hydrotalcite have a good synergistic effect. The recommended ratio is: 5.2:1
Characteristics of Aluminum Pentaerythritol
The calcium-zinc stabilizer of the pentaerythritol-aluminum system is used in U-PVC calendered sheets for good plasticization and each roll is well wrapped, which solves the problem that ordinary calcium-zinc stabilizer is prone to poor plasticization and does not wrap the roll;
Sheets produced with aluminum pentaerythritol have uniform color, no holes, cracks, bubbles that are not conducive to use, no bumps and wrinkles, and almost no fish eyes.
The amount of HCl absorbed by 1g of aluminum pentaerythritol is 27.01mg.
The amount of HCl absorbed by 1g zinc stearate is 92.71mg.
The amount of HCl absorbed by 1g of calcium stearate is 104.76mg.
The amount of HCl absorbed by 1g of lead salt stabilizer is 278.72mg.
This shows that the ability of aluminum pentaerythritol to absorb HCl is weaker than that of CaSt2, ZnSt2 and lead salts, and aluminum pentaerythritol can very well improve the thermal stability of PVC. Therefore, we can conclude that aluminum pentaerythritol improves the thermal stability of PVC by replacing active chlorine atoms in the PVC chain. Stable performance.
Because the chlorine atom in the PVC chain has a relatively high electronegativity (about 3.16) and the Al atom in aluminum pentaerythritol has a relatively low electronegativity (about 1.61), the reaction proceeds more easily and a stable complex is formed.
Usage Guidance of Aluminum Pentaerythritol
Aluminum pentaerythritol can be used as PVC heat stabilizer, etc. Used for general industrial transparent products; used together with zinc soap, generally this product can be used for PVC soft products and hard products. It is not easy to precipitate and can help optimize scaling and precipitation phenomena.
1) Aluminum pentaerythritol can not only help optimize the initial color of PVC samples and extend the thermal stability time, but also help reduce heat loss and the concentration of conjugated chains;
2) When aluminum pentaerythritol is used as a single stabilizer, the recommended dosage is 3.84phr, and the thermal stabilization time is 52.86min;
3) Compounding experiment shows:
When the mass ratio of aluminum pentaerythritol and zinc stearate is 3/1, the synergy is better. It not only has excellent initial color, but also has ideal long-term stability;
When the ratio of aluminum pentaerythritol to calcium stearate is 3/1, the synergy is better, but overall the synergy is not as good as aluminum pentaerythritol and zinc stearate;
When the ratio of aluminum pentaerythritol to hydrotalcite is 5/1, the synergy is better, not only has excellent initial color, but also ideal long-term stability;
When aluminum pentaerythritol is combined with β-diketone, the long-term stability effect is good.
