Description

A kind of preparation method of antipollution road mark paint

Technical field

The present invention relates to traffic facilities technical field, particularly relate to a kind of preparation method of road mark paint.

Background technology

Be different from other coating, road mark paint not only will stand rolling of wheel after construction molding, graticule after shaping in use also will stand the friction of the silt particle from road table, greasy dirt, the pollution of the soil such as clod, the destructions such as the etch of rainwater, this makes the environment for use of graticule all want much severe compared with the environment for use of the common coating of other types.

Existing hot-melting type, solvent-borne type or aq. type road mark paint, after construction molding, its antifouling property is all very poor, and this is at urban road, shows particularly evident in especially northern urban road.No matter in the north or south, through after a while after road mark paint construction molding, especially after the winter that rainwater is fewer, these graticule materials are all easy to the soil such as pickup flying dust, earth, greasy dirt, graticule is made to become unintelligible, overall appearance poor effect, affects traffic safety.

In traditional road mark paint, heat fusing road mark coatings is all adopt low-molecular-weight dioctyl phthalate (DOP) (DOP) or dibutyl phthalate (DBP) etc. as softening agent main component usually, in the use procedure of graticule, low-molecular-weight softening agent easily moves to graticule surface from gage mark coating, increases the probability of the soil such as flying dust, earth on pickup road surface; On the other hand, the film forming matter of heat fusing road mark coatings is all adopt petroleum resin or Gum Rosin usually, the adhesive attraction of graticule to soil is further increased because thermoplasticity Gum Rosin or petroleum resin when temperature is higher (in summer, bituminous pavement surface temperature can up to more than 80 DEG C) be easy to deliquescing; Heat fusing road mark coatings all adopts very coarse filler, such as 20-100 object quartz sand, glass microballon etc. simultaneously, and after coating film forming, under the rolling of wheel, graticule surface is very coarse, and this also can reduce the contamination resistance of graticule; What the water base property road mark paint in traditional road gage mark coating, solvent type paint for road markers were similar to heat fusing road mark coatings is all adopt thermoplastic resin, and after film forming, coarse surface is all unfavorable for the lifting of the antifouling property of graticule simultaneously.Patent (ZL200710061727.0) provides a kind of epoxy resin that utilizes as two component road mark paints of film forming matter, it is a kind of gage mark coating being specifically designed to cement pavement being easy to come off for graticule on cement pavement and developing, although this gage mark coating film susceptibility to temperature variation after film forming itself reduces greatly, but, because the dry and hard time is long, usually more than 2 hours are wanted under room temperature, the long dry and hard time not only to cause in graticule film forming solidification process easily polluting dirty, also as easy as rolling off a logly causes traffic jam.

Application number is that the application for a patent for invention of 201010154496.X discloses a kind of high-dirt-resistance road mark coating and method for making thereof, although it possesses certain antifouling property, but because it is dual-component coating, component is many, cost is high, high to applying processing requirement, clearly show in the specification sheets of this patent application " coating of the present invention strictly forbids A, B two component contacts in spraying or blade coating in face of ground; otherwise can antedating response, cause coating to be scrapped." and pay attention to antifouling property due to this patent application transition, cause the bonding force of itself and road not high, make the service life reduction of product.

In sum, the antifouling property of existing road mark paint is all also undesirable, is badly in need of a kind of road mark paint with high stain resistance of research and development.

Summary of the invention

The object of the invention is to the preparation method proposing a kind of antipollution road mark paint, the coating prepared of the inventive method adopts single-component design, has anti-soil and the strong feature of bonding force concurrently, to overcome the deficiency of road mark paint in prior art.

For reaching this object, the present invention by the following technical solutions:

A kind of preparation method of antipollution road mark paint, described coating is made up of following component by weight percentage: mean particle size is the quartz sand 14-18% of 20 μm, mean particle size is the Paris white 16-20% of 20 μm, mean particle size is the mica powder 16-20% of 10 μm, 320 object glass microballon 6-8%, polyethylene wax 1.4-1.8%, EVA hot-melt adhesive 3-4%, titanium dioxide 4-5% w3 softening agent 2-3%, HG-613 fluorocarbon surfactant 2-3%, GW150 antistatic agent 1-2%, surplus is C5 petroleum resin; Described preparation method is:

1) quartz sand, Paris white, mica powder, glass microballon and titanium dioxide are put into mixer mixing 2-4 hour, make it be uniformly dispersed;

2) in mixer, polyethylene wax, EVA hot-melt adhesive and petroleum resin are added, remix 3-5 hour;

3) anti-staining agent, fluorocarbon surfactant and antistatic agent is finally added, remix 2-4 hour;

4) mixing uniformity is checked, qualified rear packaging.

C5 petroleum resin, it is as the raw material of roadmarking hot-melt coating, has withstand voltage, wear-resisting, that anti-soil, good fluidity, rate of drying are fast advantage, is applicable to bituminous pavement and cement pavement, has excellent anti-yellowing change and ageing-resistant performance.Adopt more fine-grained quartz sand, calcium carbonate and mica powder can strengthen the smooth finish of coating surface as filler, and improve the apparent sense of coating, and play resistant to pollution ability, adopt the collocation of varigrained filler simultaneously, improve non-skid property, wear resistance, the shock-resistant and resistance toheat of roadmarking, also can have good consistency with petroleum resin, the bonding force of coating and road particularly can be made greatly to improve.Glass microballon can improve the reflective function of gage mark coating, makes this gage mark coating line style sense organ under car light irradiation obvious.Polyethylene wax can improve the smoothness of gage mark coating, resistance to blocking, the effect such as resistance to marring and pollution resistance.With w3 softening agent substitutes dioctyl phthalate (DOP) of the prior art, can play better antifouling effect.Add the antifouling property that HG-613 fluorocarbon surfactant improves coating further, titanium dioxide, as the pigment of white line coating, has good anti-aging, anti-uv-ray.EVA hot-melt adhesive effectively can improve gage mark coating toughness and the adhesive property with ground.

From the above, beneficial effect of the present invention is:

1) the present invention adopts one-component, and component quantity is few, and cost is low, and preparation method is simple, store and apply require low.

2) the present invention is from filler granularity, the contamination resistance adding many-sided raising coating such as polyethylene wax, replacement Conventional plasticizers and interpolation tensio-active agent.

3) while the antifouling property improving coating, note the raising with the bonding force of road, make the adhesive property on coating and ground excellent, greatly improve the work-ing life of coating.

4) in addition, coating uvioresistant prepared by the present invention, anti-aging, anti-skidding, wear-resisting, shock-resistant and cold-hot circulation, the traditional performance of visible road graticule is also excellent than prior art.
