Description
Technical field
The present invention relates to gage mark coating technical fields, and in particular to a kind of hot melt type gage mark coating and preparation method thereof.
Background technology
Road mark paint is a kind of safety label, and a kind of " special voice ", and traffic safety management department utilizes
Road mark paint zoning vehicle traveling lane, canalized traffic reduce vehicle and the person to reach reinforcement traffic safety management
The purpose of accident and beautifying city road.Therefore, relatively high for the performance requirement of road mark paint, it usually needs construction is fast
Dryness, visibility, Rut resistance, low-temperature resistance and high temperature resistant, wear-resisting, rainwater reflective etc., and not with vehicle population
It is disconnected soaring, in order to extend the service life of gage mark coating, extend the replacement cycle, usually also needs to gage mark coating with good anti-
Dirty performance, or even be required to absorb vehicle exhaust to a certain extent, make certain contribution for purification air environment.
In order to make gage mark coating meet requirement, composition of raw materials and preparation method for heat molten type etc. carry out
A large amount of innovative research, it is desirable to be able to enhance the performances such as toughness, wearability, visibility, pollution resistance, anti-aging so that graticule
Coating can overcome the cracking of winter embrittlement, summer feel like jelly deformation and under anti-rut behavior is poor, night and rainwater impregnate it is reflective visually
The defects of effect is poor.If Chinese patent CN2005100476095 discloses a kind of nano composite hot melt type gage mark coating, by adding
Enter nano-scale fiber, nanoscale whisker, micron order fiber, micron order whisker etc. and improves the wear-resisting of gage mark coating as reinforcing material
Property and freedom from cracking ability, but cause gage mark coating layer be cracked the reason of in addition to the high temperature resistant of dope layer itself, low-temperature resistance and anti-vehicle
Except rut performance, also on the one hand the reason is that since road surface can deform under high temperature, low temperature or hyperbaric environment, due to road surface
Deformation tendency and gage mark coating it is inconsistent, so as to cause gage mark coating be cracked even fall off.Therefore, except the patent only discloses
It is outer come the wear-resisting and crack resistance energy for improving graticule to the improvement of gage mark coating itself formula, it does not disclose needs and passes through raising
The mutual cooperation on gage mark coating and road surface improves the consistency of the two deformation, to overcome cracking and the obscission of gage mark coating
Related content.
For another example, at present for the night visibility of gage mark coating and rainy day visual effect improved ameliorative way, usually
It is to be realized by adding the conventional method of the reflectorized materials such as simple glass microballon, but the conventional roads material such as glass microballoon is usual
All it is that graininess is present among gage mark coating, in use, with vehicle tyre friction and road-cleaning operation etc.
Abrasive action cause reflectorized material to fall off, and then significantly reduce the reflecting effect and service life of graticule, need through
Renovation processing often is carried out to graticule.
Therefore, a new technique direction and realization method is provided for the improvement of every comprehensive performance of roadmarking, it is right
There will be important milestone significance in the technological innovation and sound development of gage mark coating.
