1results about How to "Enhanced network structure" patented technology

This invention relates to the field of composite material technology and discloses a crack-resistant and wear-resistant paint and its preparation method. The method includes pretreatment of fillers, preparation of modified resin matrix, grinding of dispersing aids, crosslinking and curing stages, and aging treatment. By plasma activation treatment of ceramic microspheres, the surface activity of the filler is enhanced, and its interfacial compatibility with the resin matrix is ​​improved, avoiding early cracking of the coating due to poor interfacial bonding. At the same time, the activated filler and nano-alumina form a gradient-dispersed reinforcing network structure in the matrix, improving the overall density and wear resistance of the coating. A composite system of epoxy-modified acrylic resin and polyurethane prepolymer is used. Through the reaction of isocyanate curing agents with the active groups in the resin during the crosslinking and curing stage, a stable structure is formed, enhancing the toughness and adhesion of the paint film, thereby inhibiting cracking and peeling of the coating during use.
