Description

Decoration of exterior wall is with fluorocarbon coating and manufacture method
Technical field
The present invention relates to a kind of decoration of exterior wall with fluorocarbon coating and manufacture method, be used for protection, the decoration of concrete structure exterior wall surface.
Technical background
Available coagulation soil skin coating adopts synthetic resin emulsion, adds that auxiliary agent and color stuffing are formulated, and its weak point is coating efflorescence easy to change, easy, and contamination resistance is poor, and weathering resistance is poor, and the artificial accelerated aging time only is individual hour of hundreds of.
Summary of the invention
The technical problem to be solved in the present invention: avoid above-mentioned weak point of the prior art and provide that a kind of manufacture method is easy, the decoration of exterior wall of good, the water-thinned Normal temperature of characteristics, its durability of coating with protection environment is with fluorocarbon coating and manufacture method.
The technical solution used in the present invention
Decoration of exterior wall fluorocarbon coating of the present invention, it is characterized in that vinylidene fluoride water-based fluorine emulsion by 1 weight part, 0.005 the Natvosol of weight part, 0.02 the poly carboxylic acid sodium of weight part, 0.002 the alkylphenol polyoxyethylene of weight part, be the two the deionized water of 3 times of weight parts of poly carboxylic acid sodium and alkylphenol polyoxyethylene, 0.002 the polyether-modified dimethyl polysiloxane of weight part, 0.002 2-amino-2-methyl-1-propanol, 0.01 the titanium dioxide of weight part, 0.06 the talcum powder of weight part, 0.02 the kaolin of weight part, 0.06 2 of weight part, 2,4-trimethylammonium-1, the 3-pentanediol mono isobutyrate, 0.01 the sodium polyacrylate of weight part, 0.001 the polyurethane-modified polyethers of weight part, 0.0005 the aerosil powder of weight part is formed, wherein the particle diameter of aerosil powder is 1~100nm.
The decoration of exterior wall that the adopts manufacture method of fluorocarbon coating, it is characterized in that by vinylidene fluoride water-based fluorine emulsion 1 weight part, deionized water dissolving with alkylphenol polyoxyethylene 3 times of weight parts of the two of the poly carboxylic acid sodium of 0.02 weight part and 0.002 weight part with it, the Natvosol that adds 0.005 weight part then therein, 0.002 the polyether-modified dimethyl polysiloxane of weight part, 0.002 the 2-amino-2-methyl-1-propanol of weight part, its temperature is controlled at 25 ℃, behind the high-speed stirring 0.5h, the aerosil powder that under condition of stirring, adds 0.0005 weight part, 0.01 the titanium dioxide of weight part, 0.06 the talcum powder of weight part, 0.02 the kaolin of weight part, grind 0.5~1h with sand mill then, add 2 of 0.06 weight part afterwards, 2,4-trimethylammonium-1, the vinylidene fluoride water-based fluorine emulsion of 3-pentanediol mono isobutyrate and 1 weight part adds the sodium polyacrylate of 0.01 weight part at last, 0.001 the polyurethane-modified polyethers of weight part is made the decoration of exterior wall fluorocarbon coating.
Decoration of exterior wall fluorocarbon coating of the present invention, the aerosil that is added a certain amount of auxiliary agent, a certain amount of color stuffing and surface process special processing by vinylidene fluoride water-based fluorine emulsion is formulated.In vinylidene fluoride water-based fluorine emulsion; the bond energy that is higher than C-H because of the bond energy of the C-F in its molecule; negative charge is more concentrated on the fluorine atom; electronic cloud gathers; make the accessible carbon atom of fluorine atom, hidden the C-C key, promptly fluorine atom has been protected the C-C key; durability of coating, solvent resistance, abrasion resistance are increased, particularly have excellent weather resistance.In addition, the coating that vinylidene fluoride water-based fluorine emulsion forms, its surface free energy is low, and it is wetting that its surface is difficult to, and therefore has good contamination resistance energy.The deionized water that uses is by the deionized water of tap water through the exchange of zwitterion exchange column.The polyether-modified dimethyl polysiloxane that uses helps to eliminate the bubble in the coating.The pH value that the 2-amino-2-methyl-1-propanol that uses helps to regulate coating improves dispersing of pigments efficient.The poly carboxylic acid sodium that uses can provide dispersed efficiently to color stuffing, makes dope viscosity stable.The alkylphenol polyoxyethylene of using can effective wetting color stuffing, and keeps the stability of coating.Sodium polyacrylate, the polyurethane-modified polyethers that uses helps to improve the thixotropy and the application property of coating, improves the stability in storage of coating.The aerosil that uses helps to improve the thixotropy and the application property of coating, improves the stability in storage of coating, and improves and film to the reflection potential of sunlight.
The present invention's beneficial effect compared with prior art
1, decoration of exterior wall fluorocarbon coating of the present invention has good environmental protection, the characteristics of ambient cure, and its coating has good weathering resistance, solvent resistance, contamination resistance, abrasion resistance, and its artificial accelerated aging test reaches 2000h.Can be used for protection, decoration and the renovation construction of concrete structure exterior wall surface, also can be used for the decoration construction of masonry type building outside surface.
2, the decoration of exterior wall of the present invention manufacture method of fluorocarbon coating, technology is simple, need not specific installation.
3, the decoration of exterior wall of the present invention ratio of performance to price height of fluorocarbon coating.
Embodiment 1
The decoration of exterior wall of the present invention manufacture method of fluorocarbon coating.In stainless charging basket, by vinylidene fluoride water-based fluorine emulsion 1 weight part, deionized water dissolving with alkylphenol polyoxyethylene 3 times of weight parts of the two of the poly carboxylic acid sodium of 0.02 weight part and 0.002 weight part with it, the Natvosol that adds 0.005 weight part then therein, 0.002 the polyether-modified dimethyl polysiloxane of weight part, 0.002 the 2-amino-2-methyl-1-propanol of weight part, its temperature is controlled at 25 ℃, behind the high-speed stirring 0.5h, the aerosil powder that under condition of stirring, adds 0.0005 weight part, 0.01 the titanium dioxide of weight part, 0.06 the talcum powder of weight part, 0.02 the kaolin of weight part, grind 0.5~1h with sand mill then, add 2 of 0.06 weight part afterwards, 2,4-trimethylammonium-1, the vinylidene fluoride water-based fluorine emulsion of 3-pentanediol mono isobutyrate and 1 weight part adds the sodium polyacrylate of 0.01 weight part at last, 0.001 the polyurethane-modified polyethers of weight part is made the decoration of exterior wall fluorocarbon coating.The raw materials used commercially available product that all adopts.
This coating has good environmental protection, the characteristics of normal temperature cure, and its coating is by manually adding The speed degradation shows that the gloss retention of 2000h is more than 80%; Acid resisting test soaks Steep the H in 10%2SO 4In the solution 7 days, it filmed intact. With being coated with of acrylic acid aqueous coating Film test is compared, and artificial accelerated aging test is 20% through the 500h gloss retention, and produces Efflorescence; Film through acid resisting test, impregnated in 10% H2SO 4In the solution 7 days, produce drum Bubble, flavescence.
