Description
Technical field
It is specifically a kind of that there is enhanced water resistance environment-friendly type lacquer and its preparation the present invention relates to building material technical field
Method.
Background technique
Raising with people to coating for internal and external wall cosmetic requirement, lacquer with its unique appearance and performance increasingly
Liked by everybody, many high-end residentials, garden even high buildings and large mansions are all covered with paint, lacquer, colour wash, etc. and the natural stones such as natural granite, marble
The very similar lacquer of material appearance.
But common lacquer coating every time rain after can all whiten, this is because the water resistance of coating it is bad,
It absorbs caused by moisture.Formula is the reason is that water-soluble or hydrophilic table need to be added in synthesis in the acrylic emulsion selected
Face activating agent, some producers are in order to increase emulsion intercalation method, surfactant used excess significantly, after causing coating to form a film
Stay the water resistance for greatly reducing coating in the coating.Therefore, designing one kind has enhanced water resistance environment-friendly type lacquer, at
The problem of for urgent need to resolve.
Summary of the invention
The purpose of the present invention is to provide one kind to have enhanced water resistance environment-friendly type lacquer and preparation method thereof, on solving
State the problem of proposing in background technique.
To achieve the above object, the invention provides the following technical scheme:
One kind having enhanced water resistance environment-friendly type lacquer, including below according to the raw material of parts by weight: deionized water 130-180
Part, 0.02-0.09 parts of polypropylene fibre, 1-5 parts of hydroxyethyl cellulose, modified silicone acrylic emulsion 220-300 parts, coalescing agent 4-8
Part, 0.4-1.8 parts of propylene glycol, 0.4-1.6 parts of fungicide, 0.4-1.8 parts of defoaming agent, 0.4-1.5 parts of polyurethanes thickener, pH
1-3 parts of regulator, 600-720 parts of kayexalate Modified Quartz Sand.
As a further solution of the present invention: including below according to the raw material of parts by weight: 140-160 parts of deionized water is gathered
0.04-0.08 parts of tacryl, 2-4 parts of hydroxyethyl cellulose, modified silicone acrylic emulsion 240-270 parts, 5-7 parts of coalescing agent, third
0.8-1.2 parts of glycol, 0.6-1 parts of fungicide, 0.8-1.2 parts of defoaming agent, 0.6-1 parts of polyurethanes thickener, pH adjusting agent
1.5-2 parts, 625-675 parts of kayexalate Modified Quartz Sand.
As further scheme of the invention: including below according to the raw material of parts by weight: 156 parts of deionized water, poly- third
0.06 part of alkene fiber, 3 parts of hydroxyethyl cellulose, modified 260 parts of silicone acrylic emulsion, 6 parts of coalescing agent, 1 part of propylene glycol, fungicide
0.8 part, 1 part of defoaming agent, 0.8 part of polyurethanes thickener, 1.8 parts of pH adjusting agent, kayexalate Modified Quartz Sand 655
Part.
As further scheme of the invention: the preparation method of the modified silicone acrylic emulsion is to weigh suitable the third cream of silicon
The neopelex of 0.4 ‰ times of weight is added in liquid, carries out mechanical stirring 20- with the stirring rate of 300-700r/min
40min, then it is warming up to 65-75 DEG C, butyl acrylate and concentration is added for 10% sodium persulfate aqueous solution, with 500-1200r/
The stirring rate of min is warming up to 90 DEG C after carrying out mechanical stirring 20-40min and carries out heat preservation 60-160min, is subsequently cooled to room
Temperature, investment carry out machinery emulsification 40min into high-shear emulsion machine to get the modified silicone acrylic emulsion；By to silicone acrylic emulsion
It is modified, the water-soluble or hydrophilic surfactant effectively reduced in lotion stays in the coating after coating film forming
Situation, and then effectively increase the water resistance of coating.
As further scheme of the invention: the coalescing agent is alcohol ester 12, dibutyl phthalate or poly-
One of acid imide or a variety of combinations；The fungicide is isothiazolinone biocide agent；The defoaming agent is organosilicon
Oxygen alkane；The pH adjusting agent is 2-amino-2-methyl-1-propanol.
As further scheme of the invention: the preparation method of the kayexalate Modified Quartz Sand is to weigh
Suitable quartz sand is warming up to 260 DEG C according to the heating rate of 2 DEG C/min, keeps the temperature 2h, be cooled to room temperature, be ground into 40-100
Mesh powder, into aforementioned powder be added 0.02 ‰ times of weight kayexalate, mechanical stirring be uniformly mixed, then into
The ultraviolet light irradiation 10-20min of row is to get the kayexalate Modified Quartz Sand；By being modified to quartz sand, have
Effect improves the water resistance of coating；The quartz sand is that In Altay, xinjiang gobi cobble is crushed quartz sand, and partial size is
The quartz sand and partial size of 10-40 mesh are that the quartz sand of 80-120 mesh respectively accounts for 50%.
The preparation method with enhanced water resistance environment-friendly type lacquer, steps are as follows:
1) deionized water and polypropylene fibre are weighed according to parts by weight, puts into fiberizer and carries out defibrination process, then altogether
With investment into dispersion machine, coalescing agent, propylene glycol and fungicide are sequentially added while stirring, carry out ultrasound point after mixing
20-30min is dissipated, mixture A is obtained；
2) modified silicone acrylic emulsion is weighed according to parts by weight, mixture A obtained in step 1) is added while stirring, mixing is equal
Hydroxyethyl cellulose, pH adjusting agent, defoaming agent and polyurethanes thickener, mechanical stirring 30- are successively slowly added to after even
40min obtains mixture B；
3) mixture B obtained in step 2) is put into blender, is slowly added to polystyrolsulfon acid while stirring
Sodium Modified Quartz Sand, be uniformly mixed to get.
As further scheme of the invention: in step 1), the supersonic frequency of the ultrasonic disperse is 10-20kHz.
