Abstract

The invention relates to a macromolecular ceramic composite coating, which is prepared from the following raw materials: 6 to 20 parts of bisphenol A medium temperature epoxy structural adhesives, 6 to 10 parts of ceramic powder, 3 to 6 parts of diethylenetriamine, 6 to 12 parts of active additives, 1 to 3 parts of silane coupling agents, 2 to 8 parts of carbon fiber reinforcement bodies, 10 to 20parts of silicon carbide, 2 to 6 parts of bonding agents and 1 to 5 parts of polyurethane. The ceramic powder is added into the macromolecular ceramic composite coating; the ceramic powder can improve the wear resistant performance of the coating, so that the service life of the macromolecular ceramic composite coating can be prolonged; through the addition of polyurethane and carbon fiber enhancement bodies, the toughness of the macromolecular ceramic composite coating is improved; the brittleness after the bonding agent curing is improved.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a polymer ceramic composite coating and a preparation method thereof. Background technique [0002] Composite materials are new materials that people use advanced material preparation technology to optimize the combination of material components with different properties. The matrix materials of composite materials are divided into two categories: metal and non-metal. The metal matrix commonly used is aluminum, magnesium, and copper. , titanium and its alloys; non-metallic substrates mainly include synthetic resin, rubber, ceramics, graphite, carbon, etc., and reinforcing materials mainly include glass fiber, carbon fiber, boron fiber, aramid fiber, silicon carbide fiber, asbestos fiber, whisker, metal . [0003] However, due to the relatively simple composition of the traditional polymer ceramic composite coating, the wear resistance of the polymer ceramic composite...
