Abstract
The colored bitumen is comprised of bitumen, low-molecular weight polymer, pigment, dispersing agent and covering agent, which can be made into colored bituminous concrete. Said bitumen has color and the properties of it, such as softening point, cold resistance and abrasion-resistance can be raised. ADVANTAGE-. production process is simple and cost is low.
Description
The present invention relates to a kind of material of construction, more specifically say so a kind of color asphalt and concrete thereof.
At present commercially available various pitches are single black, and it makes the road that builds up and place, and not only tone is single, and are lifeless and that the driver is easily produced in the process of driving over a long distance is tired, thereby cause traffic accident.In order to overcome this defective, some color concretes had once been developed abroad.A kind of prescription of color concrete is disclosed: rubble: screenings: coarse sand: fine sand: stone flour: chromic oxide (pigment): binder mixture=22.0%: 14.9%: 31.5%: 15.8%: 3.5%: 5.0% (weight percent) in clear 57～108167, wherein binder mixture is made up of hybrid resin and pitch, and its proportioning is as follows: hybrid resin: pitch=100: 10～70 (part).This proportioning medium pitch content seldom only accounts for about 1.5～3% of total content, Gu this influences the quality on road surface.
Also disclose a kind of color concrete in US4332620, its prescription is as follows: vermiculite: sandstone: crumb rubber: pitch: ferric oxide=2～8: 45-80: 6-18: 10-20: 4-20 (weight percent).In this patent, asphalt content very big (account for 10～20%, the Ordinary Rd asphalt content is 4.5-5.5%), along with the wearing and tearing on road surface, some harmful and noxious substance may fly upward with dust in the pitch, causes the pollution to ambient atmosphere.Rubber consumption is also more in this patent, because the cold and hot variation of weather may cause ageing of rubber, causes the road surface to produce crack performance.Because pitch, rubber consumption are big, and the amount of sandstone is less relatively, causes bituminous concrete intensity not high, cost is also high simultaneously again.Above-mentioned two patent medium pitchs are black, and not wounded look, therefore, still are black when using pitch when independent.During this external preparation color concrete, all to add pigment at every turn, trouble not only, and also easily irregular colour is even.Japan has announced a kind of painted paving binders in clear 62～189203, this binding agent is also referred to as color asphalt usually, but it does not contain the pitch composition, it is all to be made up of petroleum resin and organic high molecular polymer, its easy coloring, and color category is many, but cost an arm and a leg, raw material sources are restricted, and technology is also complicated, is difficult to lot production.And owing to what use all is polymkeric substance, the Heating temperature height, and therefore, set time is short, is unfavorable for constructing operation.In addition, this product will be heated to 160～170 ℃ in use, and power consumption is big, expense is also high.
The object of the invention provides that a kind of cost is low, raw material is easy to get, technology is simple, easy working color asphalt and concrete thereof.
The present invention is achieved like this.Raw material of the present invention comprises pitch, low-molecular(weight)polymer, pigment, covering agent and dispersion agent.The low-molecular(weight)polymer that is adopted among the present invention, its density and pitch are approaching, and softening temperature, fusing point are also approaching with pitch, and easy and pitch mixes, and especially can mix with the paraffin in the pitch, thereby changes asphaltic nature, and softening temperature is raise, and helps the softening resistance in summer.The polymkeric substance that the present invention adopts has winter hardiness, thermotolerance, chemical-resistant resistance and wear resistance.It can bear the adhesion layer of pigment in concrete mineral aggregate particle surface formation one in addition, makes pigment even.The low-molecular weight polymer that the present invention adopts is a polyethylene, and its molecular weight is 2000～5000.
The pigment that the present invention adopts is pollution-free, and ferric oxide, chromic oxide and pigment dyestuff Fast Yellow G are arranged.
Add dispersion agent among the present invention and can make pigment homogenization and in bright gay colorization quickly.Dispersion agent has calcium stearate, Magnesium Stearate, sodium oleate, sodium laurylsulfonate.
The present invention also adopts covering agent to hide the bituminous true qualities, reduces its blackness so that the color of pigment is apparent.For some expensive raw material, added covering agent simultaneously, can suitably reduce the consumption of pigment, thereby reduce cost.As prepare green chromic oxide, available this method reduces its consumption, but still keeps the colourity of requirement.The general titanium dioxide, zinc white, zinc barium powder (upright powder) of adopting.
The prescription of color asphalt of the present invention is as follows:
Pitch 52.5-57.5%;
Low-molecular weight polymer 0.27-1.6%;
Pigment 28-45.4%;
Dispersion agent 0.05-1.3%;
Covering agent 0.5-15.3%.
Said ratio is weight percentage.
The preparation technology of color asphalt of the present invention is as follows:
In heating stirrer, adding is heated to 130～150 ℃ of fusions by the pitch of proportional quantity, stir into homogeneous, and remain under this temperature, add low-molecular weight polymer again, stir evenly fusion after, heat covering agent, dispersion agent and the pigment of proportional quantity more successively, after noting a kind of material of each adding, add another kind of after must stirring again.After treating all to add, keep this temperature to mix and stir 2 minutes, be cooled to room temperature product.
In sum as seen, pitch of the present invention is painted and be with chromatic.Utilize color asphalt can be mixed with color asphalt concrete, simplified the color matching operation greatly.Various component environmental pollutions are little in the color asphalt of the present invention, can utilize original production unit and construction technology, thereby investment cost is little, operate also easyly, are suitable for industrial production.The road that the concrete that is mixed with by color asphalt of the present invention is paved into is difficult for aging, be full of cracks, and have softening resistance energy preferably.The raw material that the present invention adopts is easy to get, inexpensive.
The present invention utilizes color asphalt can be mixed with the concrete of different size as required, is fit to the needs on various road surfaces.
The prescription of color asphalt concrete of the present invention is as follows:
1200 parts of aggregate chips;
680 parts of sands;
120 parts of stone flours;
130～220 parts of color asphalts
The manufacture craft of color asphalt concrete of the present invention is as follows:
Place baking oven (or drying machine) to be preheated to 140～160 ℃ aggregate chips, sand, and in another container, pitch is heated to 130～150 ℃ and is melt into homogeneous.Mix and stir in the amalgamator of pouring the aggregate chips and the sand of heat into preheating by proportioning, add fused color asphalt by proportional quantity then, mix and stir, temperature is controlled at 130～150 ℃, adds stone flour again, mixes and stirs discharging in 2 minutes.
