Embodiment 1
[0022] The present invention is a calculus laminated polymer composite material in-situ reaction molding method. The raw material of the base layer 11 is polyethylene, the raw material of the bonding layer 10 is ethylene-vinyl acetate copolymer, and the raw material monomer of the functional layer 9 is caprolactam. The molecular modifier is at least one of carbon nanotubes, layered silicate, and inorganic nanoparticles, the catalyst is sodium hydroxide, sodium methoxide or sodium ethoxide, and the activator is acid chloride, acid anhydride, isocyanate, N-acylation At least one of lactam compounds. First, add caprolactam and polymer modification additives into the vacuum reactor, turn on the vacuum pump to reduce the pressure and heat to melt, vacuum dehydration at 70~120℃, maintain 10~20min; release the vacuum, add the catalyst and heat to 90~130 under vacuum conditions ℃ for a certain period of time; fill the inert gas nitrogen to balance the pressure in the kettle with the ou...
