摘要
腈纶废料经高温、高压、催化水解后复配，可得到一种新型铸造粘结剂。当粘结剂加入量为4％，其拉伸强度可达2.80MPa以上，湿压强度可达0.022MPa。同合脂相比，该粘结剂具有发气量少，强度高，无污染等特点。
Waste nitrilon fibre can be hydrolyzed catalytically in a autoclave the hydrolysate can be compounded to a new casting adhesive. When the addtion amount of the adhesive is 4%, the tensile strength of the sand cores is over 2. 8 MPa and the wet compression strength over 0. 022 MPa. Contrasting to synthetic fat binder, this adhesive has the advantages of less gas releasing, High strength and no pollution.
