Abstract

The influence of chemical and physicochemical modification on the mechanical properties of polyurea coatings has been studied. It has been demonstrated that the use of aromatic and aliphatic polyisocyanates, as well as polymer modification with minor amounts (no more than 2 wt %) of polytetrafluoroethylene and polymethylsiloxane, makes it possible to control the elastic modulus of the coating in the range 22–172 MPa. The results obtained determine the possibility of producing a family of coatings with a spectrum of construction properties, from those characteristic of rubbers to those typical of plastics, using a limited range of parent monomers and small amounts of modifying agents.

改性聚脲绝缘涂料的力学性能

摘要

研究了化学和物理化学改性对聚脲涂料机械性能的影响。已经证明,使用芳香族和脂肪族多异氰酸酯,以及使用少量(不超过 2 重量%)聚四氟乙烯和聚甲基硅氧烷进行聚合物改性,可以将涂层的弹性模量控制在 22– 172兆帕。获得的结果决定了使用有限范围的母体单体和少量改性剂生产具有一系列结构特性的涂料系列的可能性,从橡胶的特性到塑料的特性。
