Abstract

The invention provides a preparation method of reactively diluted alkyd resin. A reactive diluent comprises one or more of the following functional group structures.

Description

Synolac of a kind of active dilution and preparation method thereof
Technical field:
The invention provides a kind of preparation method of Synolac.Especially, the invention provides a kind of preparation method of Synolac of active dilution.Belong to chemical field.
Background technology:
Synolac still occupies absolute predominance at present in synthetic resins is used.Its good over-all properties, broad range of application, easy application mode and cost advantage all are that other resins can't replace in a short time.Synolac also along with the expansion of range of application and the requirement of environmental protection, is constantly released follow-on product.CN200610053684.7 discloses a kind of Synolac that utilizes ionic liquid to dilute, and has reduced the consumption of toluene or dimethylbenzene.CN03805230.X discloses a kind of utilization and has contained the alkyd resin composition that pentacyclic novel active thinner substitutes whole benzene kind solvents.
Summary of the invention:
The invention provides a kind of Synolac of active dilution, add reactive thinner to be made into active dilution in the Synolac Synolac, the Synolac of this activity dilution can further be prepared the alkyd varnish of high solids content.Described reactive thinner can participate in curing reaction after Synolac is made into paint, become the part in the paint film resin segment, can not move.
The preparation method of the Synolac of a kind of active dilution of the present invention, it is characterized in that, the preparation method is as follows: reactive thinner and Synolac are mixed by the proportioning example, and the above-mentioned resin take aromatic hydrocarbon, aliphatic hydrocarbon, ester, ketone or alcohol as dissolution with solvents namely obtains the active Synolac that dilutes.
The ratio of described reactive thinner is 0.1%~50% of alkyd solids component.Preferably, the formula ratio of reactive thinner is 5%~30% of alkyd solids component.
Described reactive thinner includes but not limited to one or more in amino acid, acid amides, imines, hydrazides, etheric acid, methyl aceto acetate, AAEM, TriMethylolPropane(TMP) acetylacetic ester, tetramethylolmethane acetylacetic ester, TriMethylolPropane(TMP) diacetyl acetic ester, tetramethylolmethane diacetyl acetic ester, trimethylolpropane tris acetylacetic ester, tetramethylolmethane triacetyl acetic ester, tetramethylolmethane tetrem ethyl sodio acetoacetic ester, Acetolon, 1,3 dimethyl acetone-1,3-dicarboxylate, ketenes, aldehyde ketone, diketone, biuret, the trimeric cyanamide.
Described reactive thinner comprises one or more in the following structure of functional groups:
Figure BSA00000704150200021
The Synolac of active dilution of the present invention, its viscosity is little, can be used for preparing the high paint that admittedly contains, and reduces the consumption of solvent.
The Synolac of active dilution of the present invention join paint film after, described reactive thinner can participate in film formation reaction, becomes the part of paint film, can not move or volatilize.
Synolac used solvent in joining lacquer of active dilution of the present invention includes but not limited to hydro carbons, ester class, ketone or the alcoholic solvents such as dimethylbenzene, solvent oil, ethyl acetate, butylacetate, 1-Methoxy-2-propyl acetate, acetone, methylethylketone, methyl alcohol, ethanol.
The Synolac of active dilution of the present invention also can be used the solidifying agent such as biuret, polyisocyanates, isocyanate addition product in joining lacquer.
The Synolac of active dilution of the present invention can also further add auxiliary agent and/or filler in joining lacquer.
