摘要：在浅色松香酯合成后期加入主抗氧剂、辅助抗氧剂、热稳定剂、光稳定剂和光吸收剂等各种添加剂,能明显提高它的热稳定性和耐候性。对添加量进行正交试验,分析得出高稳定性浅色松香甘油酯的较佳添加剂用量为主抗氧剂5 g.kg-1,辅助抗氧剂3 g.kg-1,热稳定剂3 g.kg-1,光稳定剂0,光吸收剂5 g.kg-1时,经松香甘油酯的热稳定性试验后加纳色号为1.5;经耐候性试验后增重率为0.14%,加纳色号增幅为3.0,优于市场上销售的同类产品。
Primary antioxidant, secondary antioxidant, thermal stabilizer, light stabilizer and UV absorber were used in preparing light-colored rosin glyceride, which could improve rosin glycerideSs thermal stability and antiaging. Better dosage of primary additives were attained through cross experiment, which were 5 g·kg^-1 primary antioxidant, 3 g·kg^-1 secondary antioxidant, 3 g·kg^-1 thermal stabilizer, zero light stabilizer and 5 g·kg^-1 UV absorber. Color grade of rosin glyceride was 1.5 after thermal stability test, and weight gain rate was 0.14%, color grade was 3.0 after anti-aging test. The performance of the rosin glyceride is better than other kin products on markets. [Ch, 6 tab. 7 ref.]
