The paint comprises the following components in parts by weight: 20-30 parts of rutile titanium dioxide, 1-2 parts of polyacrylate pigment dispersing agent, 0.5-1.5 parts of sodium tripolyphosphate, 4-6 parts of ester alcohol, 0.8-1.2 parts of fatty acid low alcohol acid ester, 22-32 parts of glass beads, 16-18 parts of quartz sand with the granularity of 320-500 meshes, 10-14 parts of calcite powder with the granularity of 320-500 meshes, 0.2-0.4 parts of hydroxyethyl cellulose ether, 42-46 parts of acrylic latex binder, 3-5 parts of micron-sized glass fibers, 1-3 parts of micron-sized polypropylene fibers and 10-16 parts of water, wherein the diameters of the two types of fibers are 1-20m and the length-diameter ratio is (20-30):1.
Description
Technical field
The present invention relates to traffic facilities technical field, relate in particular to a kind of road mark paint.
Background technology
Developing rapidly of national highway, is badly in need of functional, the multi-purpose road mark paint of exploitation, to meet, improves round-the-clock high visibility, all many-sided requirements such as the feature of environmental protection, weather resistance, easy construction.
Hot melt type gage mark coating with its fast drying, be coated with the features such as thickness, long service life, reflective persistence are good, current being used widely on China Higher level highway.Due to expressway, must adopt reflector marking, and reflector marking needs glass microballon, this just requires graticule coating to reach certain thickness, guarantee glass microballon difficult drop-off, thereby guarantee reflective persistence, this is that general normal temperature solvent based coating is beyond one's reach, so hot-melt traffic paint occupies dominant position on China Higher level highway always.
From existing bibliographical information and patent formulation, this coating mainly adopts the solid resins such as petroleum resin, rosin remodeling resin, xylene resin as filmogen, using titanium dioxide, zinc oxide, medium chrome yellow medium yellow, lead-chrome yellow etc. as pigment, light reflecting material multiselect glass microballon, for multiselect, dibenzoic acid lipid, mineral oil, plant wet goods are as softening agent.But these coating generally all have the following disadvantages, because the fragility of petroleum resin, modified rosin resin is generally all larger, film and easily chap, wear no resistance, particularly outstanding at the lower geographical environment of temperature or season.To this, common adopted remedial measures is to improve the content of softening agent, but this is subject to again the restriction of the aspects such as cost, workability.
Application number is that 200510047609.5 Chinese patent application discloses a kind of nano composite hot melt type gage mark coating and preparation method thereof, by weight percentage, this hot melt gage mark coating basic composition is filmogen lO～25%, pigment 3～8%, filler 40～70%, extraordinary strongthener 0.5～4%, glass microballon 14～25%, other auxiliary agent 1～5%, feature is that extraordinary strongthener contains nano-scale fiber, nano level whisker, micron order fiber, micron order whisker.Its preparation process is as follows: first pour filmogen into mixing kettle, then add auxiliary agent, after stirring, add successively pigment, filler, glass microballon, extraordinary strongthener under agitation condition, after stirring, go out still pack.
Although this hot melt roadmarking, has excellent abrasion resisting, the ability of freedom from cracking, its essence is still a kind of hot melt type gage mark coating, and it is difficult to overcome the following defect of hot melt gage mark coating:
1. while constructing, need be heated to 180 ℃ of left and right, easily cause workmen's scald accident, working security is poor;
2. need heating for multiple times, energy consumption is large, and construction is inconvenient;
3. the content of volatile organic compound severe overweight in construction, has certain harm and pollution to human body and environment;
4. need to remove old line during recoat, cost increases, and has reduced operating efficiency.
Therefore, need a kind of alternative hot-melt coating of the prior art of water-based paint of freedom from cracking performance badly.
Summary of the invention
The object of the invention is to propose the water base reflecting roads sign coating of a kind of freedom from cracking, this coating is water-based paint, has overcome the above-mentioned defect of heat reflow paint, and has possessed higher freedom from cracking and wear resisting property, is suitable for using on motorway.
For reaching this object, the present invention by the following technical solutions:
The water base reflecting roads sign coating of a kind of freedom from cracking, this coating is comprised of following component in weight part: Rutile type Titanium Dioxide 20-30 part, polyacrylate pigment dispersing agent 1-2 part, tripoly phosphate sodium STPP 0.5-1.5 part, ester alcohol 4-6 part, lipid acid lower alcohol acid esters 0.8-1.2 part, granulated glass sphere 22-32 part, 320-500 order quartz sand 16-18 part, 320-500 order calcite in powder 10-14 part, hydroxyethyl ether cellulose 0.2-0.4 part, acrylic latex base-material 42-46 part, micron order glass fibre 3-5 part, micron order polypropylene fibre 1-3 part, wherein the diameter of two kinds of fibers is 1-20 μ m, length-to-diameter ratio is 20-30: 1, water 10-16 part.
Preferably, this coating is comprised of following component in weight part: 25 parts of Rutile type Titanium Dioxides, 1.5 parts of polyacrylate pigment dispersing agents, 1 part of tripoly phosphate sodium STPP, 5 parts of ester alcohol, 1.0 parts of lipid acid lower alcohol acid esters, 27 parts of granulated glass spherees, 17 parts of 320-500 order quartz sands, 12 parts of 320-500 order calcite in powder, 0.3 part of hydroxyethyl ether cellulose, 44 parts of acrylic latex base-materials, 4 parts, micron order glass fibre, 2 parts of micron order polypropylene fibres, wherein the diameter of two kinds of fibers is 1-20 μ m, and length-to-diameter ratio is 20-30: 1, and 13 parts, water.
Beneficial effect of the present invention:
1) to answer water be that carrier be take acrylic latex and made aq. type reflecting roads sign coating as main raw material in the present invention, during this gage mark coating construction, without heating, once sprays film forming or blade coating film forming, energy consumption is low, easy construction, working security is high, has overcome the defect of heat reflow paint.
2) micron order glass fibre and micron order polypropylene fibre in coating, have been added, and adjust the component proportion of conventional water-based paint, make the consistency of fibre fractionation and all the other components good, play synergy, can make coating there is excellent freedom from cracking and wear resisting property.
3) between coating and granulated glass sphere, attached outstanding power is strong, while coating fast drying, and good weatherability, shock-resistant and corrosion, meets the user demand of motorway.
