By using methyl methacrylate (MMA) as the harder monomer, butyl acrylate (BA) as the softer monomer, acrylic acid (AA) as the functional monomer, acetoacetoxyethyl methacrylate (AAEM) as the crosslinking monomer, tert⁃butyl peroxybenzoate as the initiator, propylene glycol butyl ether as the solvent for prepared self⁃crosslinking acrylate emulsion by free radical solution polymerization and phase inversion, and the emulsion could be self⁃crosslinked after baking at high temperature without additional crosslinking agent. This article mainly studied the influence of acrylic acid, acetoacetoxyethyl methacrylate and curing time on the performance of the polyacrylic resin dispersion and the film property. The results show that the optimized formula is as follows: The dosage of AA and AAEM are 3.5% and 5.0% of the total monomer mass, respectively, and the baking time is 1.0 h at a curing temperature of 180 ℃. FT⁃IR and GPC analysis showed that AAEM was successfully attached to the molecular chain of acrylic resin; SEM and particle size analyzer analysis showed that the TG of the film is latex particles were spherical and uniformly distributed; DSC analysis showed that after the synthesized resin dispersion is significantly increased after the synthesized resin dispersion is baked at high temperature for a period of time.

       In order to minimize the loss of life and property caused by sudden marine oil spills, it was necessary to apply intellectual technology to marine oil spills management system, combining human wisdom and the wisdom of computer technology, wisdom marine oil spill management system was established. The basic concepts and technology development were introduced and the wisdom and intelligence technology would be applied to marine oil spill management system. The wisdom marine oil spill management was initially established to reduce or even avoid the occurrence of oil spills at sea, to protect the marine environment, and to achieve sustainable and healthy development of marine and depot business.
