The above-mentioned high finish coat varnish of a kind of aqueous polyurethane, wherein thickener is aqueous association type polyurethane thickener.
A kind of above-mentioned high finish coat varnish of aqueous polyurethane, wherein auxiliary agent include in antifoaming agent, levelling agent, dispersant extremely
Few one kind.
The above-mentioned high finish coat varnish of a kind of aqueous polyurethane, wherein the hydroxyl in hydroxy acryl acid resin accounts for described containing hydroxyl
The mass percent of base acrylic resin is 4.1%.
The preparation method of the high finish coat varnish of a kind of aqueous polyurethane of the present invention, wherein include the following steps:
Step 1:Prepare raw material according to following components and parts by weight:
Step 2:By in step 1 hydroxy acryl acid resin, water, coupling agent, isopropanol, filler, thickener and help
Agent mixes, high-speed stirred 20-30min;
Step 3:Curing agent in step 1 is added in the product after step 2 stirring, high-speed stirred 20-30min,
30min is stood again.
The invention has the advantages that:
1, the high finish coat varnish of aqueous polyurethane of the invention greatly reduces VOC's compared to solvent type finishing coat on the market
Volatilization, protects environmental and human health impacts;
2, the selection of filler improves the wearability and impact resistance of the high finish coat varnish of aqueous polyurethane of the present invention;
3, the selection and use of coupling agent, enables filler preferably to be disperseed;
4, thickener selects aqueous association type polyurethane thickener, and inorganic is not selected to thicken class, avoids inorganic increasing
Thick dose of extinction effect has ensured the high photosensitiveness of the present invention.
Specific implementation mode
