  • Environment-friendly and flame-retardant abradable seal coating material with ultra-low density and use method thereof
    Patent number: 12281194
    Abstract: Disclosed is an environment-friendly and flame-retardant abradable seal coating material with an ultra-low density and a use method thereof. The seal coating material includes a component A and a component B packaged separately; the component A includes 20-30 wt % of a curing agent for bisphenol A epoxy resin, 20-30 wt % of a liquid phosphorus-containing curing agent, 20-40 wt % of a hollow glass microbead, 1-5 wt % of 2,4,6-tris(dimethylaminomethyl)phenol, 5-15 wt % of dimethyl methylphosphonate and 0.5-3 wt % of a silane coupling agent; the component B includes 30-40 wt % of a bisphenol A epoxy resin, 30-40 wt % of a liquid phosphorus-containing epoxy resin, 20-30 wt % of a hollow glass microbead, 0-10 wt % of a liquid acrylonitrile-butadiene rubber and 0.5-3 wt % of a silane coupling agent. The method includes: mixing the component A and the component B to obtain a coating, and applying the obtained coating to a surface of a part for curing.
