Description
Technical field
The present invention relates to technical field of coatings, more particularly to a kind of functional coating varnish and preparation method thereof and answer
With.
Background technique
Indoors in fitment process, coating varnish has extremely strong decoration effect because having many advantages, such as high glaze, the high grade of transparency
Fruit can be used for various substrate surfaces, have both protection and decoration functions, is widely used.However, with indoor decorating and refurnishing materials
Increasingly diversified, a large amount of synthetic material such as glue, plate etc. is used, so that indoor content of formaldehyde is tight after the completion of finishing
Weight is exceeded, is exposed in this environment, can cause damages to the health of human body for a long time.With people's environmental consciousness and health perception
Gradually increase, the content of indoor formaldehyde increasingly attracts people's attention.Since formaldehyde volatilizees from finishing material, there are weeks
Phase is long, the features such as persistently volatilizing, previous purifying formaldehyde technology, such as plant purification, physical absorption, photocatalytic conversion are deposited mostly
It is palliative the disadvantages of purification efficiency is low, clean-up effect is unstable.And current conventional coating varnish on the market, mostly
It can only play the role of protection and decoration, the effect of without having both purifying formaldehyde.

Material combination makes the functional coating varnish of preparation not only have the effect of long-acting purifying formaldehyde, but also dry be more suitable for
Dry speed.
The amino modified AA emulsion is by methyl methacrylate, propylene in one of the embodiments,
Sour N-butyl, isobornyl methacrylate and function monomer are copolymerized, and the function monomer is selected from acrylamide, N- hydroxyl first
At least one of base acrylamide, N- butoxy methyl acrylamide, crotonamide, ethernamine and amylene amide；It is described
The dosage of function monomer is prepare monomer gross mass used in the amino modified AA emulsion 15%~25%.
Above-mentioned amino modified AA emulsion, by by methyl methacrylate, n-butyl acrylate, methyl-prop
Olefin(e) acid isobornyl thiocyanoacetate and function monomer copolymerization, introduce AA emulsion by chemical modification for the amino in function monomer
In, then compound with other raw materials, make the functional coating varnish of preparation that not only there is the protection of conventional coating varnish, decoration effect
Fruit, and have the effect of long-term purifying formaldehyde.
Thickener is hydrophobically modified polyurethane thickener in one of the embodiments,.
The dispersing agent is polyacrylic acid sodium salt aqueous dispersion in one of the embodiments,；The wetting agent is different
Structure alcohol polyoxyethylene ether wetting agent；The coalescing agent is alcohol ester 12；The antifreezing agent is selected from ethylene glycol, propylene glycol and high score
At least one of sub- antifreeze auxiliary agent of polyalcohols；The defoaming agent is siliceous class defoaming agent.
The preservative is selected from least one in Kathon CG and 2- benzisothiazole (BIT) in one of the embodiments,
Kind；The mould inhibitor is selected from iodopropynyl butyl formate (IPBC), methyl formate (BCM) and the different thiophene of 2- n-octyl -4-
At least one of oxazoline -3- ketone (OIT).
The mould inhibitor is that iodopropynyl butyl formate and 2- n-octyl -4- are different in one of the embodiments,
The combination of thiazoline -3- ketone.
Above-mentioned functionality coating varnish, when mould inhibitor is the combination of IPBC and OIT, anti-mold effect is best.
The application also provides a kind of preparation method of above-mentioned functional coating varnish, and concrete scheme is as follows:
A kind of preparation method of functional coating varnish described in any of the above embodiments, comprising the following steps:
Part water, dispersing agent, wetting agent, defoaming agent, antifreezing agent and coalescing agent are mixed 3~5 minutes；
Amino modified AA emulsion is added, mixes 3~5 minutes；
Thickener and another part water is added, mixes 3~5 minutes；
Preservative and mould inhibitor are sequentially added, is mixed 3~5 minutes, remaining water is added, mixes 3~5 minutes, obtains institute
State functional coating varnish.
Further, mixed rate is no more than 400r/min.
It is above-mentioned functionality coating varnish preparation method, simple possible, by by water, dispersing agent, wetting agent, defoaming agent,
Antifreezing agent and coalescing agent first mix, and obtain the more suitable system of viscosity, add amino modified AA emulsion,
Demulsifying phenomenon caused by being directly added into lotion is prevented, makes the functional coating varnish of preparation that can not only keep coating varnish
Characteristic, and the effect of long-acting purifying formaldehyde can be had both；Preparing functional coating varnish by substep can be improved yield rate.
