Embodiment 1

[0018] Raw material ratio: 30 parts by weight of sorbitol modified linseed oil medium oil alkyd resin, 20 parts by weight of TDI modified soybean oil alkyd resin, 0.2 parts by weight of drier (cobalt drier and rare earth drier each 0.1 wt. ), 2 parts by weight of coloring pigment, 1 part by weight of antirust pigment, 8 parts by weight of talcum powder of 1200-1300 mesh of inorganic filler, 15 parts by weight of low boiling point organic solvent sherwood oil, 0.5 part by weight of dispersant, and 0.1 part by weight of thickener , 0.1 parts by weight of polyether modified polydimethylsiloxane defoamer and 0.2 parts by weight of leveling agent. The preparation steps are as follows:

[0019] (1) Add sorbitol-modified linseed oil mid-oil alkyd resin, TDI-modified soybean oil alkyd resin, dispersant and some low-boiling organic solvents into the dispersion container, and stir evenly at 1000 rpm;

[0020] (2) Reduce the speed to 500rpm, add coloring pigments, anti-rust pigments, in...

Abstract

The invention discloses a super-quick-drying alkyd primer coating and a preparation method therefor. The coating comprises the following components: sorbitol modified linseed oil medium-oil alkyd resin, TDI modified soya oil acid alkyd resin, a drier, a coloring pigment, an antirust pigment, inorganic filler, a low-boiling-point organic solvent, a dispersant, a thickener, a defoamer and a flatting agent, wherein the drier is a mixture of a cobalt drier and a rare earth drier in an arbitrary proportion; the low-boiling-point organic solvent is petroleum ether, ethyl ether, dichloromethane or n-pentane. According to the primer coating disclosed by the invention, in a condition that the dry film thickness of the coating is 20-30 [mu]m at an environmental temperature of 18-30 DEG C, the surface drying time is not longer than 0.5 hour and the hard drying time is not longer than 12 hours; other performances of the coating are equivalent to those of a common alkyd coating. By applying the primer coating twice a day, the coating efficiency of the alkyd coating is improved by over 2 times which is far superior to that of the existing common alkyd primer.

Description

technical field [0001] The invention relates to the technical field of primer coatings, in particular to an ultra-fast-drying alkyd primer coating and a preparation method thereof. Background technique [0002] At present, the anti-corrosion protection of steel materials and cement materials is mainly carried out by painting anti-corrosion primers, which have good adhesion, moisture resistance, primer contact and atmospheric corrosion resistance, etc., but there are still some problems, such as drying time Longer, poor anti-sagging performance and anti-skinning performance, etc., the construction is seriously affected by the seasons, and the practical application range is very limited. Contents of the invention [0003] In order to overcome the above-mentioned problems in the prior art, the present invention provides an ultra-fast-drying alkyd primer coating, the surface drying time is within half an hour, and the hard drying time is within 12 hours, which is especially su...
