运输设备部件用聚脲交联粒子、滑动部件以及运输设备部件用聚脲交联粒子的制造方法
摘要：
提供一种运输设备部件用聚脲交联粒子，其耐酸性高，当使其含有在涂膜中时能够提高长期的油保持性，能够长期维持高的滑动性。本发明的运输设备部件用聚脲交联粒子是由在存在水的情况下，具有2个以上官能团的自乳化型异氰酸酯和具有环结构且具有2个以上官能团的非自乳化型异氰酸酯进行反应得到的反应物构成的粒子，其交联密度为1×10‑4摩尔/g以上。
摘要（英）：

Polyurea crosslinked particles for a transport device member are provided that have high acid resistance, increase long-term retainability when included in a coating film, and are capable of maintaining a high sliding property for a long time. The polyurea crosslinked particles for a transport device member are particles formed of reactants of a self-emulsifying isocyanate having two or more isocyanate groups and a non-self-emulsifying isocyanate having two or more isocyanate groups and having a ring structure in the presence of water and a crosslink density thereof is 1×10−4 mol/g or more.
