Quick-drying primer-topcoat two-in-one steel member paint and preparation method thereof

Abstract

The invention relates to quick-drying primer-topcoat two-in-one steel member paint and a preparation method thereof. The steel member paint is prepared from the following components by weight: 20-38 parts of synthetic resin, 10-20 parts of antirust pigment, 6-12 parts of coloring pigment, 5-11 parts of fillers, 1-4 parts of auxiliary agents, and 32-50 parts of solvents. The preparation method comprises the following steps: adding 85-95 wt% of solvents into a stirring tank, adding synthetic resin, stirring to completely dissolve the synthetic resin; adding part of auxiliary agents, antirust pigment, coloring pigment, and fillers into the stirring tank to obtain color slurry; grinding the color slurry by a sand grinder to allow the fineness of the color slurry to be not more than 40 microns; adding the rest of the auxiliary agent into the grinded color slurry, and adjusting the viscosity to 120-150 s by using the rest of the solvent to obtain the quick-drying primer-topcoat two-in-one steel member paint. When compared with the prior art, the quick-drying primer-topcoat two-in-one steel member paint of the invention has good antirust performance and drying speed, does not sag after thick coating, can realize undercoating at a time, is suitable for protection and decoration of large and medium sized steel members, and is simple in preparation method and wide in application scope.

Description

technical field [0001] The invention relates to a paint and a preparation method thereof, in particular to a quick-drying bottom surface integrated steel structure paint and a preparation method thereof. Background technique [0002] The current steel structure paint is mainly composed of alkyd antirust paint and alkyd blend paint. The function of antirust paint is mainly to slow down the rust of steel, and the alkyd blend paint mainly plays a decorative role. When painting, first apply alkyd antirust paint, and then apply alkyd blended paint after drying. Due to the limited space of the steel structure factory, after the anti-rust paint is applied, it must wait for it to dry (generally more than 10 hours) before applying the topcoat, which greatly restricts the production capacity of the steel structure factory. Topcoat, which also increases labor costs. Contents of the invention [0003] The object of the present invention is to provide a quick-drying bottom-surface-in...
