| 6. | Its bend strength is 144 . 1 mpa , impact strength is 13 . 5 kj / m2 and martin heat - resistant temperature is 160 . and the heat decompounding temperature of the resin is 350 , which is confirmed by the tga of cured resin 同时对改性后树脂固化物进行热失重分析,确定树脂固化物热分解温度为350 。表明通过改性后的双马树脂具有较好的力学性能和耐热性。 |
| 7. | A . the preparation of sliding ink for plastic printing . b . , widely used in ht e preparation of double components epoxy paint and epoxy adhesive , the curing matter own fine mechanical and electrochemical property ; it is also applied in the manufacture of low temp B二聚酸与多元胺反应生成具有活性胺基的聚酰胺,广泛应用于制造双组份环氧油漆及环氧粘结剂,固化物具有良好的机械电化学等性能。 |
| 8. | Filling flexibilizer , such as epoxy terminal block , polyurethane ether structure , thiokol and liquid ctbn to the system of expoxy - mannich amide , through the test on shear strength , bounding elasticity modulus and break strength of cured products , the different fuction could be found using different flexibilizers 摘要在环氧酚醛胺体系中使用端环氧基聚氨酯醚、聚硫橡胶、液体丁腈橡胶等活性增韧剂,通过对固化物剪切强度、弯曲弹性模量及断裂强度的测试对比,可以看出不同增韧剂效果不同。 |
| 9. | It is discovered that the diameters of silicon rubber decrease and the number of silicon rubber increase by the dc electric pre - stress applied during solidifying of silicon rubber - toughened epoxy resins . the effect is independent of the polarity of electric pre - stress , but it is dependent of the intensity of electric pre - stress 本文通过实验研究证实:在硅橡胶改性环氧树脂的固化过程中所施加直流预电应力导致了固化物中硅橡胶相数量增多、尺寸减小;并且,预电应力的这种效应与预电应力的极性无关,但与预电应力的水平有关。 |
| 10. | In addition , it is found that dc electric field weakens the effect of release agent and strengthens the binding strength between epoxy resins and anode in the condition of the existence of release agent . but this effect of electric field is not discovered between epoxy resins and cathode 另外,本文通过实验研究还证实:在有脱模剂存在的情况下,固化过程中直流电场的存在会弱化脱模剂的作用进而强化环氧树脂固化物与金属正电极间的粘接强度,但直流电场对环氧树脂固化物与金属负电极间的粘接强度没有明显影响。 |
