摘　　要：在传统呋喃树脂工艺的基础上,通过对反应条件、工艺参数等因素进行试验,找出了树脂低温结晶的原因,并通过引入改性剂降低了树脂的游离甲醛,提供了一种游离甲醛低、型砂强度高、无结晶的铸造用自硬呋喃树脂工艺。On the basis of the traditional furan resin technology, the reason for the crystallization of furan resin at low temperature was found out through the investigations of reaction conditions and process parameters for the resin synthesis process. By introducing a modifier, the free formaldehyde content of furan resin was reduced. In the paper, a kind of no-bake furan resin for casting was provided with low free formaldehyde, high strength of molding sand and without the problem of crystallization.
