Abstract

The invention discloses a synthesis method of zinc acrylate resin. The synthesis method comprises the following steps of (1) firstly, adding a solvent and a zinc-containing compound into a reaction kettle, and heating to the return temperature; (2) dropwise adding a mixture of an acrylic monomer, rosin and part of initiator at the return temperature to initiate reaction; and (3) adding the rest part of initiator to generate the zinc acrylate resin. The one-step synthesis method of the zinc acrylate resin, disclosed by the invention, has the advantages of simplicity in production control, easiness to obtain raw materials, small product component fluctuation, reaction step reduction and energy consumption reduction.

Description

technical field [0001] The invention relates to a method for synthesizing zinc acrylate resin, in particular to a method for synthesizing zinc acrylate resin in one step. Background technique [0002] Marine fouling organisms mainly grow on the surface of the hull below the waterline, coastal facilities, and submarine cables. If marine fouling organisms grow attached to the bottom of the ship, it will increase the quality of the hull, and at the same time, the friction coefficient of the hull will increase greatly, which will affect the speed of navigation and increase energy consumption. [0003] Organotin self-polishing antifouling coatings were developed in the mid-1970s. Organotin compounds have the advantages of broad-spectrum bactericidal properties, low poisonous concentration, stable exudation rate, long antifouling period and self-polishing in seawater, so they were widely used in the 1990s. However, it was later found that the accumulation of organotin compounds ...
