Description
Technical field
The present invention relates to a kind of self-cross linking type waterborne road marking paints and preparation and using method.
Background technology
Along with development and national economy, enter 21 century highway in China total kilometrage and reached 1,250,000 kilometers.Flourish road construction has promoted the development of traffic paint.Present used traffic paint about 90% is the solvent-thinned paint of Air drying.The volatile organic compounds (hereinafter to be referred as VOC) that this class traffic paint contains is up to 650g/l.In system lacquer or when drawing the system road sign, the volatilization of VOC all can work the mischief to operator and environment; Also have a kind of hot melt road marking paint, though low, the good endurance of VOC content needs heating and melting during construction, difficulty of construction is big, will root out old coating earlier during recoat, very trouble.The waterborne road marking paints that grow up the eighties in 20th century because of its VOC content is low, is paid close attention to deeply.But because boiling point, vaporization heat, the polarity of water, all than the solvent height that has the solvent-borne type traffic paint now, moreover water also has hydrogen bond to exist, therefore, the disadvantage of waterborne road marking paints is that time of drying is long, poor water resistance and poor with road adherence, thereby restricted the development and the application of waterborne road marking paints.Adopt the fast dried traffic paint of a kind of high solid to address the above problem at present abroad, this class traffic paint is to be main base-material with negatively charged ion pure-acrylic emulsion or benzene emulsion, adds small amounts of water soluble or aqueous dispersion type amine-containing polymer and volatile alkali and mixes.This waterborne road marking paints is to make amine-containing polymer be in the nonionic state with high-load volatile alkali, prevents that other anionic groups interact in amine-containing polymer and emulsion and the system, to keep the traffic paint shelf-stable.During use, volatile alkali volatilization, the protonated positively charged ion that becomes of amine-containing polymer, it with system in other negatively charged ion combine cohesion, reach fast dried.The solids constituent of this waterborne road marking paints is about 70%, and not sticking tire is lower than 10 minutes time of drying.But, because amine-containing polymer is abundant inadequately in coating preparation process nonionicization, make and take place easily system lacquer or storage period such as phenomenons such as viscosity increase, microcosmic cohesion, cakings, and these waterborne road marking paints are when some roads are on probation at home, still exist poor water resistance, anti-staining property poor, meet rain or high temperature and descend, paint film feels like jelly, cause pull-away, influence the work-ing life of road sign.
Summary of the invention
The objective of the invention is to, a kind of high-solid level, shelf-stable are provided, the self-cross linking type waterborne road marking paints of the easy construction that paint film water tolerance, wear resistance and sticking power are good and preparation and using method.
Realize the technical scheme of the object of the invention: a kind of self-cross linking type waterborne road marking paints, it is main base-material with the anionic self-crosslinking silicopropyl emulsion with good mechanical stability and Calcium ion stability, solids constituent at least 45%, this coats with lacquer shelf-stable, solids constituent at least 75%, each component and consumption thereof are as follows:
20～50 parts of anionic self-crosslinking silicopropyl emulsions,
1～5 part of distilled water, 1～5 part of methyl alcohol,
1～5 part of film coalescence aid, 1～3 part of dispersion agent,
0.1～1 part of wetting agent, 0.1～0.5 part of biocide mildewcide,
0.1～1.5 part of defoamer, 20～80 parts of pigment and fillers,
More than be weight part.
In the above-mentioned waterborne road marking paints, described anionic self-crosslinking silicopropyl emulsion has stone soft shell structure, and siloxanyl monomers and part acrylic acid esters monomer are nuclear, and N-methylol (methyl) acrylamide, Acrylic Acid Monomer and part acrylic acid esters monomer are shell; The high-speed shearing equipment that its mechanical stability reaches with 4000～5000 rev/mins stirred emulsion 30 minutes, and emulsion is not condensed, do not lumpd; Its Calcium ion stability reaches with emulsion and 5%CaCl
2After mixing in 5: 1 by volume, do not condense, do not lump in 48 hours.This organosilicon crylic acid latex with nucleocapsid structure, there are grafting, IPN or ionic bonding between the nucleocapsid, be different from general multipolymer or copolymer mixture, under the situation that same materials is formed, hardness of paint film, wear resistance, drying property etc. after the film forming, can further improve, package stability is better.
In the above-mentioned waterborne road marking paints, described film coalescence aid is one or more in alcohol ester-1 2, phenylcarbinol, propylene glycol monobutyl ether, propylene glycol phenylate, the dipropylene glycol methyl ether; Described dispersion agent is the sodium salt of poly carboxylic acid or in the ammonium salt one or more, the Rhodoline DP-270 of Rhodia for example, SN-5027, SN-5029, SN-5040 or the SN-5468 etc. of Japanese Nuo Puke company; Described pigment is titanium dioxide or chrome yellow, and filler is one or more in lime carbonate, quartz sand, barium sulfate, talcum powder, wollastonite, the silicon powder.The wollastonite and/or the silicon powder of handy difficult hydrolysis more help making paint film to have hard skeleton, and then improve its water tolerance and wear resistance; All the other each components can be selected for use in the commercially available product from be generally used for emulsion paint.
