Described anti-settling auxiliary agent is organobentonite, polyesteramide or stem Viscotrol C.
Described component B solidifying agent is HDI tripolymer isocyanic ester.
The preparation method of described solvent-based two-component coating, comprises first component and component B, the preparation of first component:
(1) put into pimelinketone and mibk, in a reservoir, then add acrylic resin modified, stir 5-10min, uniformly fluid;
(2), in above-mentioned uniform fluid, drop into defoamer, dispersion agent, pigment, filler, anti-settling auxiliary agent successively, finish rear stirring 20-30min;
(3) sand mill grinding, by above-mentioned stirring liquid is sent into, until qualified fineness (≤60 μm);
(4), by above-mentioned grinding filter, then stir, be transferred to the qualified viscosity of product (10000 ~ 20000 mPa.s), obtain first component;
The preparation of component B: directly take solidifying agent for subsequent use.
Described solvent-based two-component coating by coating method be disposable spray finishing, namely after the requirement being first component gross weight 2/10 to ten/10ths by component B weight is mixed, on the workpiece needing spraying, direct single level or multi-level spraying spraying are once, after reaching specified requirement thickness, from doing 24h and get final product; When temperature below 5 DEG C, relative humidity be greater than 80% time, will not spray.
Positively effect of the present invention is as follows: due in solvent-based two-component formulation for coating material, have employed acrylic resin modified, coating overall performance is improved greatly, its corrosion resistance and good, strong adhesion, physical strength are high, decorate properties is good, can the erosion of long-time resistance to strong acid, meets the quality standard of anticorrosive coating product; Because coating processes is disposable spray finishing, so substantially increase production efficiency, decrease configuration that is artificial and equipment, greatly reduce the energy consumption (energy consumption can reduce 60%-70%) of production; The present invention is widely used in the equipment and Infrastructure of the manufacturing enterprises such as power plant desulfurization device, high temperature stacks, smeltery, storage battery factory, obtains the abundant accreditation in market.
Embodiment
The present invention have chosen three embodiments, and the weight part of its raw material is as shown in the table:
