Embodiment 1

[0028] Add 500g iron oxide red pigment into the kneader, then mix 2.5g KH-560 coupling agent and 5g ethanol in the beaker, add 0.5g deionized water and stir again for 2min, then spray the mixed liquid In the iron oxide red pigment in the kneader, mix and disperse in the kneader for 10 minutes to obtain the surface-modified iron oxide red pigment.

Embodiment 2

[0030] Add 500g of titanium dioxide into the kneader, mix 7.5g of KH-560 coupling agent and 6g of isopropanol in a beaker, add 0.75g of deionized water and stir for another 2 minutes, then spray the mixed liquid In the titanium white in the kneader, mix and disperse in the kneader for 5 minutes to obtain surface-modified titanium white.

Embodiment 3

[0032] Add 500g of phthalocyanine blue 15:0 pigment into the kneader, mix 15g of KH-560 coupling agent and 20g of isopropanol in a beaker, add 2g of deionized water and stir for another 2min, then mix the mixed liquid Spray into the phthalocyanine blue 15:0 pigment in the kneader, and then mix and disperse in the kneader for 8 minutes to obtain the surface-modified phthalocyanine blue 15:0 pigment.

Abstract

The invention discloses color paste for an epoxy floor coating. The color paste for the epoxy floor coating comprises the following components in percentages by weight: 20-70% of surface modification pigment, 25-78% of an activated diluent and 2-5% of a dispersing agent. The color paste is prepared by processes of dispersion, grinding, filtering, defoaming and the like. In the color paste prepared by the method, a silane coupling agent is used for modifying the pigment, and the prepared color paste has the advantages of high coloring power, small fineness, good storage stability, good environment safety and the like.

Description

technical field [0001] The invention relates to the technical field of fine chemicals, in particular to a color paste for epoxy floor paint and a preparation method thereof. Background technique [0002] Epoxy resin refers to a polymer oligomer containing more than two epoxy groups, and the main chain contains aliphatic or alicyclic, aromatic chain segments, which can generate thermosetting compounds through the reaction of epoxy groups. Oxygen resins are widely used in coatings, adhesives and other fields. Due to the high viscosity of epoxy resin, it is generally necessary to add active or non-active diluents to adjust the viscosity of epoxy resin, increase fluidity and prolong service life when using it, and add polyamine and other curing agents to react with it to form Thermosetting compound with excellent mechanical properties. [0003] Dust-free workshops, sports venues and other places that require clean floors are often coated with epoxy floor paint. Epoxy floor pai...
