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
The present invention relates to primer base technical field, particularly a kind of ultrafast dry alcohol acid primer coating and preparation method thereof.

Described siccative is the mixture of cobaltic drier and rare earth drier arbitrary proportion; Described low boiling point organic solvent is sherwood oil, ether, methylene dichloride or Skellysolve A.
Preferably, the parts by weight of each composition are as follows: sorbyl alcohol modification oleum lini medium oil alkyd 20 ~ 30 parts, TDI modified soyabean oil acid alcohol acid resin 20 ~ 40 parts, siccative 0.2 ~ 0.5 part, tinting pigment 1 ~ 2, rust-stabilising pigment 1 ~ 3, mineral filler 8 ~ 12, low boiling point organic solvent 10 ~ 15 parts, dispersion agent 0.2 ~ 0.5 part, thickening material 0.1 ~ 0.4 part, defoamer 0.1 ~ 0.2 part and flow agent 0.1 ~ 0.2 part.
Preferably, described low boiling point organic solvent is sherwood oil.
Preferably, described mineral filler is 1200-1300 object talcum powder.
Preferably, described defoamer is with polyether-modified polydimethylsiloxane defoamer.
Present invention also offers the preparation method of above arbitrary described ultrafast dry alcohol acid primer coating, it comprises the following steps:
(1) sorbyl alcohol modification oleum lini medium oil alkyd, TDI modified soyabean oil acid alcohol acid resin, dispersion agent and part low boiling point organic solvent are added in dispersion cup, stir under 1000rpm rotating speed;
(2) reduce rotating speed to 500rpm, add tinting pigment, rust-stabilising pigment, mineral filler and thickening material successively, promote rotating speed to 1200rpm, be stirred to fineness below 60 μm;
(3) reduce rotating speed to 800rpm, add the low boiling point organic solvent of siccative, defoamer and flow agent and remainder, stir 5-10 minute to dissolution homogeneity.
Compared with prior art, the present invention has following beneficial effect:
Priming paint of the present invention is by the selection of formula material, adopt sorbyl alcohol modification oleum lini medium oil alkyd and TDI modified soyabean oil acid alcohol acid resin as Synolac, coordinate special siccative and organic solvent, be aided with other fillers, produce excellent quick-drying performance.In envrionment temperature 18-30 DEG C of interval, in its build 20 ~ 30 μm of situations, surface drying time is not more than 0.5 hour; The time of doing solid work is not more than 12 hours; Other performance is suitable with usual alkydpaints.Application every day twice can be accomplished, improve more than the coating efficiency twice of alkydpaints, be far superior to existing common alcohol acid primer.
