Abstract
The present invention relates to heated solvent type paint for mark lines on roads, which is made from a film-forming component, pigment, a filling material, a plasticizing agent, an antisettle agent and mixed solvent. The paint has the technical characteristics that the paint can be sprayed at the medium temperature of 40 DEG C to 80 DEG C, and the solid content of the paint is from 78 to 88%. Therefore, the paint of the present invention can ensure that mark lines on roads are endurable when sprayed for one time with high thickness.
Description
Road traffic marking relieves traffic congestion, the standard vehicle operating, judges function such as traffic accident and protection pedestrains safety and become the important component part of road with it.Along with the fast development of Road construction, kind, quality and the constructional method of road mark paint are also had higher requirement.But the fast construction seasons of speed of application is long, road pavement adaptability is wide and the low advantage of unit surface graticule one-off construction cost though the normal temperature solvent type paint for road markers has.But its solids content is lower, is generally about 60%.Graticule is not durable so the final coating that adopts this kind gage mark coating to execute the roadmarking of drawing approaches.Simultaneously owing to contain 40% the organic solvent of having an appointment in this kind coating, the existence of so a large amount of organic solvents can cause bigger injury undoubtedly to producer and user's health and also physical environment caused bigger pollution simultaneously.Receive the order long advantage though hot-melting road mark paint has to use, its construction cost is higher.Hot-melting road mark paint need be heated to about 200 ℃ and could construct, and has also caused bad working environment to the user of service when consuming a large amount of fuel sources.This kind execution of coating progress is very slow and the poor slightly road surface of planeness is difficult to execute draws a graticule.More crucial problem is that this kind road mark paint is not suitable for using in the snowy area of cold.Snow the season sticking power and the poorest stage of snappiness of this kind graticule exactly in cold.The road snow removing is easy to the large-area destruction of this kind roadmarking the time when winter, and within the several months in this season owing to the temperature reason can't be mended the work of drawing to the graticule of breakage at all.Pernicious traffic accident very easily takes place in the incomplete road of graticule.
The purpose of this invention is to provide a kind of long service life, but the wide construction seasons of road pavement adaptability is long, construction speed is fast, comprehensive cost is low, can be bigger alleviate pollution level to environment, roadmarking is not damaged and the thermal solvent type paint for road markers of construction temperature between 40 ℃ to 80 ℃ when removing the snow in the winter time.
The outstanding technical characterictic of thermal solvent type paint for road markers of the present invention is: (1) uses the thermoplastic acrylic resin as the film forming component in system component.Owing to adopt the film forming component of thermoplastic acrylic resin as coating of the present invention, then make coating of the present invention at normal temperatures (25 ℃) be the higher liquid coating of viscosity.And coating of the present invention being heated to moderate temperature (40 ℃～80 ℃) in advance when drawing roadmarking executing, the viscosity of coating of the present invention then is dropped rapidly to and is equivalent to normal temperature and holds the viscosity of formulation gage mark coating and be fit to spraying and execute and draw a graticule under the equitemperature hereinto.(2) coating of the present invention is construction line under moderate temperature.Pre-heating temperature that can be by adjusting coating of the present invention uses coating of the present invention to execute a stroke roadmarking to reach the purpose of adjusting dope viscosity of the present invention with the equipment that adapts to different spray pressures and different spraying flows.(3) solids content of coating of the present invention is higher, accounts for 78～88% in the weight of coating is formed, and so then can realize thick being coated with of disposable graticule and prolongs work-ing life of graticule.Simultaneously since in the coating of the present invention the content of organic solvent in the weight of coating is formed, only account for 12～22%, relatively the reduction that the normal temperature solvent type paint for road markers is then bigger to the hazard rating of producer, user and physical environment.(4) but coating of the present invention to long by the wide construction seasons of construction road surface adaptability and snow in cold and can not destroy roadmarking season because of snow removing work.
The used film forming component of coating of the present invention is the thermoplastic acrylic resin, and its consumption accounts for 10～20% in coating reassembles into.
The used softening agent of coating of the present invention is dioctyl phthalate (DOP), dibutyl phthalate and dicyclohexyl phthalate, and its consumption accounts for 1～5% in coating weight is formed.
The used solvent of coating of the present invention is aromatic hydrocarbons, ester class, halogenated hydrocarbon, ketone, alcohols and fat hydrocarbon organic solvent.Above-mentioned solvent can adopt two kinds or three kinds of combinations to be used as the form of mixed solvent.Adjustment by solvent combination reaches the evaporation rate of solvent in the viscosity of regulating coating of the present invention and the coating.Its mixed solvent consumption accounts for 12～22% in coating weight is formed.
Used pigment, filler and anti-sedimentation agent is general titanium dioxide, lead-chrome yellow, zinc-chrome yellow, lime carbonate, ground silica, process white, talcum powder and wilkinite etc. in the coating of the present invention.It adds up to consumption to account for 55～75% in coating weight is formed.
The preparation method of thermal solvent type paint for road markers of the present invention is: add mixed solvent, softening agent, thermoplastic acrylic resin, pigment, filler and anti-sedimentation agent in dispersing and mixing equipment, become the higher liquid of a kind of viscosity at normal temperatures through dispersing and mixing technology.Be delivered to this liquid in the ball mill or sand mill grinds and disperses and become thermal solvent type paint for road markers of the present invention.
Below table--1 be two embodiment of coating of the present invention and the reference example of a normal temperature solvent-borne type gage mark coating, show--2 is the technical feature of the product of the product of two embodiment and a reference example.Table-1 embodiment and reference example
