Description
Technical field
The present invention relates to a kind of aqueous wooden ware seal coat, more particularly to a kind of SMA modified cations are acrylic acid aqueous
Woodenware transparent confinement priming paint.
Background technology
In recent years, the environment-friendly advantage that water-borne wood coating is protruded by it, health and security, one as woodwork coating
Developing direction.But in water-borne wood coating coating process, closure, water resistance often occur, temperature tolerance, grinability, ooze
The problems such as color, i.e., in real color water-borne wood coating, when being particularly the application of light or white coating, paint film is easy to change, influence paint
Film apparent property.
There is poor adhesive force in anion seal coat, the weak shortcoming of alkali resistance mostly, due to anionic emulsion particle diameter compared with
Greatly, surface tension is also very big, and general is difficult to penetrate into the tiny pore inside ground, so surface of bottom material can only be relied on
The density of film realizes the effect of back cover.
Cationic polymer is using homopolymer or copolymer made from cationic emulsifier or positively charged monomer
Emulsion, and cation acrylic seal coat has less surface tension, the permeability to ground is extremely strong, cationic galactomannan liquid energy
Reaction is crosslinked with bleeding material, the alkaline matter in ground, preferable sealing process is played；Cation emulsion surface is poly-
Compound is positively charged in itself, is that anion or non-ionic emulsion have incomparable function：Such as Key wordscationic polyacrylate
When emulsion is used for woodenware priming paint, the natural lines of timber can be made to be shown especially with true qualities；Cationic galactomannan micelle surface institute band is just
Charge groups, can make the functional groups such as ester group, hydroxyl in Key wordscationic polyacrylate emulsion and timber produce interaction, play
Certain oil sealing effect.
CN103614040A discloses a kind of aqueous wooden ware seal coat and preparation method thereof, by aqueous pure acrylic latex
5.2~10.5 parts of 80~85 parts, 6.8~7.2 parts of coalescents, 0.3~0.5 part of aqueous moistening flatting agent and water are constituted；The hair
Bright prepared aqueous wooden ware seal coat not only has excellent envelope color, rate of drying is fast, particle diameter is thin, timber can be prevented swollen
Muscle, and grinability is good, base material can be protected not to be damaged.
CN 103642342A disclose a kind of impervious color aqueous wooden ware seal coat, impervious color aqueous wooden ware seal coat,
Including following components：30~80wt% of film forming matter, 1~5wt% of coalescents, 1~10wt% of impervious color auxiliary agent, substrate wetting agents
0.1~2wt%, 10~60wt% of water and conven-tional adjuvants；Wherein described film forming matter is waterborne cation acrylic emulsion, aqueous
One kind or two or more mixing in cation-modified acrylic copolymer dispersion or waterborne cation epoxy resin ester emulsion
Thing；Impervious color aqueous wooden ware seal coat has excellent resistance to bleed energy made from the invention.
Xu Fei etc., the exploitation of the wooden ware sealing priming paint based on cation water-based acrylic resin, 2012,50 (9) are reported, and are
Improvement aqueous woodware paint caused by pigment etc. oozes out discoloration problem in use, with methacrylic acid lignocaine second
Ester, methyl methacrylate, butyl acrylate, butyl methacrylate are raw material, and cation is prepared using solution polymerization process
Water-based acrylic resin, and prepare aqueous wooden ware seal coat with it；The aqueous wooden ware seal coat have excellent permeability,
Closure and resistance to bleed.
Above-mentioned cationic acrylate seal coat, although with preferable closure and resistance to bleed, but exist resistance to
Warm nature, resistance to life product contaminative, alkali resistance, the shortcomings of poor water resistance and drying property are slow, grinability is bad.
The content of the invention
In order to solve exist technical problem, the present invention use imidizate SMA modified cations acrylic acid ester emulsion for
Film forming matter, because imidizate SMA modified cation acrylic acid ester emulsions contain SMA functional resins, can effectively improve paint film
Temperature tolerance, alkali resistance, wearability, compatibility, water resistance and excellent adhesive force, and imidizate SMA cationic acrylamides
Acid esters emulsion is a kind of nanometer micro-emulsion, and the particle diameter of emulsion reaches nanoscale (≤150nm), therefore, with very strong permeability,
Reaction can be crosslinked with bleeding material, the alkaline matter in timber, and reacts the salts substances coated formed and is fixed on boundary
On face, it will not migrate and ooze out under high temperature, super-humid conditions；Therefore, the film compactness of formation is high, with excellent closure,
Adhesive force and resistance to bleed.
Other imidizate SMA modified cation acrylic acid ester emulsions have moderate glass transition temperature, and (Tg is 30~40
DEG C), made seal coat has good film forming and quick-drying；SMA functional resins can improve the wearability of paint film
The higher hardness with offer, therefore, there is no need to addition grinding auxiliary agent all has good grinability and fillibility.
In order to solve the problems, such as techniques as described above, the present invention takes following technical scheme：Change the present invention relates to a kind of SMA
Property cation acrylic aqueous wooden ware transparent confinement priming paint, consisting of：Imidizate SMA modified cation acrylic acid ester emulsions
40%~80%, substrate wetting agents 0.1~0.5%, coalescents 1~6%, auxiliary agent 2%~5%, deionized water 15%~
60%.
Wherein, described auxiliary agent at least includes the one of defoamer, wetting agent, thickener, pH blenders and biocide mildewcide
Plant or several combinations.
Described coalescents are from diethylene glycol ethers, propane diols ethers and DPG ethers, alkoxide, propane diols
One or more of combinations.
The present invention proposes a kind of preparation method of the acrylic acid aqueous woodenware transparent confinement priming paint of SMA modified cations, prepares
Technique is as follows：Based on formulation weight ratio, deionized water, defoamer, substrate wetting agents are added in agitator tank, after being uniformly dispersed
Add imidizate SMA modified cation acrylic acid ester emulsions, then add coalescents and other auxiliary agents, regulate viscosity and
PH value, that is, be made a kind of acrylic acid aqueous woodenware transparent confinement priming paint of SMA modified cations.
The acrylic acid aqueous woodenware transparent confinement priming paint of a kind of SMA modified cations produced by the present invention, with excellent envelope
Closing property, the transparency, adhesive force and resistance to bleed, fabulous grinability and fillibility；The paint film of formation has excellent high temperature resistant
Property, alkali resistance, wearability, compatibility and water resistance；It is widely used in the aqueous wooden ware seal coat of all kinds of timber, aqueous inner-outer wall
Seal coat and other water-based industrial paint priming paint.
