摘要
叙述了改性酚醛树脂的性能、覆膜砂制备配方及其性能测定。改性后的酚醛树脂韧性增强 ,覆膜砂抗拉强度和抗弯强度明显提高 。
Properties of modified phenol resin, precoated sand preparation and property test have been narrated. It is showed that toughness of phenol resin after modified has been increased, tensile strength and transverse strength of precoated sand and collapsibility of molding sand, which have been improved obviously.
