摘要

研究了化学改性和物理化学改性对聚脲涂层力学性能的影响。研究表明，使用芳香族和脂肪族聚异氰酸酯，以及用少量(不超过2wt %)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 - 172mpa范围内。所获得的结果确定了使用有限范围的母单体和少量改性剂生产具有一系列结构性能的涂料的可能性，从橡胶的特征到塑料的典型特征。

Mechanical Properties of Insulation Coatings Based on Modified Polyurea

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.

期刊介绍： Doklady Physical Chemistry is a monthly journal containing English translations of current Russian research in physical chemistry from the Physical Chemistry sections of the Doklady Akademii Nauk (Proceedings of the Russian Academy of Sciences). The journal publishes the most significant new research in physical chemistry being done in Russia, thus ensuring its scientific priority. Doklady Physical Chemistry presents short preliminary accounts of the application of the state-of-the-art physical chemistry ideas and methods to the study of organic and inorganic compounds and macromolecules; polymeric, inorganic and composite materials as well as corresponding processes. The journal is intended for scientists in all fields of chemistry and in interdisciplinary sciences.
