    • PURPOSE: A core shell rubber modified phenol hardening agent with high molecular weight is provided which is used as a raw material of epoxy powder paint that has favorable mechanical properties and storage in low temperature so that it is widely used in producing powder paint for a coil spring or so on. CONSTITUTION: In the production of core shell rubber modified phenol hardening agent with high molecular weight, 10-70 wt% of core shell rubber resin is reacted with 100 wt% of compounds which is consisted of epoxy compounds with low molecular weight, novlac epoxy resin and fatty group epoxy resin to produce core shell rubber modified epoxy resin with low molecular weight. The produced resin is reacted with multivalent phenol in a 1.0-4.0 mole ratio. Then 1-15 wt% of promoting agent to the entire phenol hardening agent composition is added to produce high polymer core shell rubber modified phenol hardening agent with 200-1000 g/eq hydroxide radical equivalence.
    • 目的:提供高分子量的核壳橡胶改性酚醛硬化剂,用作环氧粉末涂料的原料,具有良好的机械性能和低温储存,广泛用于生产线圈用粉末涂料 春天等等。 构成:在生产具有高分子量的核壳橡胶改性酚醛硬化剂的生产中,将10-70重量%的核壳橡胶树脂与100重量%的由低分子量环氧化合物,环氧丙烯酸环氧树脂 和脂肪族环氧树脂,生产低分子量的核壳橡胶改性环氧树脂。 所生产的树脂与1.0-4.0摩尔比的多价苯酚反应。 然后加入到整个酚类硬化剂组合物中的1-15wt%的促进剂以产生具有200-1000g / eq氢氧根自由基的高聚物芯壳橡胶改性酚硬化剂。
