Beneficial effect of the present invention is:
Impact modifier ACR integrates impact-resistant modified and processing enhanced property, can increase product surface gloss and weather-proof, ageing-resistant performance, especially be applicable to outdoor goods and use, be widely used in the PVC indoor and outdoor goods such as profiled material, nontransparent sheet material, sheet material, tubing, pipe fitting.
As prevented or delay the thermal ageing of the polymeric material of PVC class, or the initiating accident sequence of thermal destruction in elimination macromolecular material, as chlorallylene structure and unsaturated link(age) in PVC; Eliminate all materials non-splitting of chain thermal degradation reaction to katalysis, as by the hydrogenchloride escaping on PVC etc., could stop or delay the thermal destruction of this type of polymeric material.Therefore the present invention's thermo-stabilizer selected and that use has following function:
1. can replace the active atom that exists in macromolecular chain (as, the chlorine atom of allylic in PVC), to obtain more stable chemical bond and to reduce to cause the possibility of dehydrochlorination reaction;
2. can, rapidly in conjunction with the hydrogenchloride splitting away off, suppress its autocatalytic action;
3. by with macromolecular material in existing unsaturated link(age) carry out addition reaction and generate saturated macromolecular chain, steady to improve this synthetic materials heat;
4. can suppress the oxidation of polyene structure with crosslinked;
5. polymeric material is had to avidity, and be nontoxic or low toxicity.
The present invention has overcome that traditional product material brittle, hardness are low, low lightness, fugitive color, uvioresistant weak effect, easy aging shortcoming, its product hardness, intensity improve, water-fast, and the correlated performances such as acid-and base-resisting, salt all significantly improve, energy-conserving and environment-protective are pollution-free, and flame retardant properties is good.
