4) HDI-TMP adduct HDI-TMP加成物 1. The synthesis technique of weathering resistance polyurethane coating curing agent HDI-TMP adduct was studied in this paper. 实验表明,TMP中水分对加成产物粘度影响很大,因此TMP需进行脱水处理;HDI-TMP加成物合成最佳工艺条件为:催化剂二月桂酸二丁基锡(DBTDL)用量0...
With TDI and TDI as materials,through chemical synthesis method,2K PU curing agent is synthesized with low free-TDI.The results show that the free-TDI content of TMP-TDI could be reduced to 0.90% when NCO/OH mol ratio is 1.9,the catalyst content is 0.1%,and the reaction temperature is ...
1.This paper narrates the manufacturing technologyof new pale color low free TDI curing agent,TDI-TMP adduct, comparing its performances indexes with traditionalTDI-TMP adductand other low free TDI curing agents in the market; and discusses main factors influencing on themanufacturing technology and...
adduct )( 前 言 TMP-TDI 加成物是双组分聚氨酯木器涂料中用 量最大的固化 剂 , 传统产品中游 离TDI 含 量 高 , 对人 体及环境的影响较 大 。 发达国家采用薄膜蒸发器来 分离聚氨酯预聚物中的游 离TDI 单体取得了很好的 效 果 , 游 离TDI 含量可以降低 到0.1% 以 下 。 此项技术 至今没有向国...
TDI-TMP预聚物 1. In order to reduce the content of —NCO in prepolymer ofTDI-TMP,caprolactam was used to block the —NCO group of prepolymer as the blocking agent. 研究用己内酰胺封闭TDI-TMP预聚物来降低游离—NCO含量的方法。 5) TDI-TMP adduct ...
