Abstract

The invention provides a method for preparing a coating material and a substrate. The coating material is applied to the surface of a substrate to improve the friction coefficient of the surface of the substrate, and includes a reactive polymer, a photoinitiator and a dispersion medium. The reactive polymerization The compound is selected from polymerizable compounds with a functionality of 2 or more, and the functional group of the reactive polymer is selected from one or more combinations of olefins, amino groups, amido groups, mercapto groups, unsaturated amides and unsaturated ethers. In the preparation method of a kind of coating paint and substrate provided by the present invention, after this coating paint is coated on the substrate surface, can significantly improve the friction coefficient of substrate surface, make substrate and The coefficient of friction between two objects in contact with the substrate is increased, and can be widely used in any field where the coefficient of friction between two contact surfaces needs to be increased.

Description

technical field

[0001] The invention belongs to the field of materials, and relates to a method for preparing a coating and a substrate. Background technique

[0002] In the field of industrial production, it often involves relative motion between two objects in contact with each other, and sometimes the coefficient of friction between the two objects needs to be as small as possible in order to reduce the resistance of relative motion. But there are also many times when the coefficient of friction between the two objects needs to be as large as possible to avoid relative movement between the two. For example, in the field of medical equipment, some brackets are generally set in the balloon, and The space between the balloon and the stent is not fixedly connected. In order to reduce the risk of unloading of the stent, we hope that there will be no relative movement between the balloon and the stent as much as possible. In the prior art, it is often only possible to choose a...
