Description
Technical field the present invention relates to a kind of road surface material, especially a kind of colored road compound.
Background technology for a long time, pavement of road has only two kinds of colors, be white pavement and dark-coloured pavement, the main raw that is used for road surface pavement is cement and pitch, these two kinds of materials have multiple functions such as bonding, waterproof, anticorrosion and insulation, thereby obtained secular application, but because its color is single, it is dull and dull that the road surface of laying seems in the boundless universe that prosperity appears.Along with expanding economy, many in the world countries begin to notice that the making colored road surface can play beautifies the environment, and give the effect of good psychological feelings, can make popular feeling feelings happy, in high spirits on the one hand; In some special traffic locations, play the effect of prompting, prompting and warning on the other hand.Thereby colored road surface causes people's interest and attention gradually as a kind of new paving technology.
Many investigators also think: the colored road surface of making different color on avenue, and can better coordinate with the art of architecture around the road, thereby embody the characteristic and the style in a country or a city.In the landscaped area, convalescence area and park, lay the square on the road surface of various colors, contrast finely with each other with meadow, trees, flowers green around the road, make environment more pleasant.
In addition, colored road surface has favorable tissue and control action kou to traffic, and the road surface of making different color is better than vertical traffic sign to a certain extent, and what it can be natural gives the officer with signal.For example, in the black spot, can making red or orange-yellow road surface, remind the officer to note intuitively, careful driving.Passing through on the road of middle and primary schools school district, making rust road surface is gone slowly vehicle deceleration, avoids dangerous generation.And good color also plays a positive role to the psychology and the emotional state of regulating navigating mate, and for example: blueness can make the driver of long-time driving in high spirits, indefatigability.
Pitch has obtained using widely in road engineering as a kind of ground surface material, and pitch mainly is made up of superpolymer, and color is aterrimus, therefore, can't make color asphalt with the color matching of other pigment, as will matching colors, must be at first to the pitch processing of decolouring.Existing pitch decolouring technology mainly is under the high temperature of 180C, finishes by reduced pressure distillation process, and is comparatively harsh to the requirement of processing condition and equipment, and pitch is after decolouring is handled, and color is still impure, still is with variegated group.During with other pigment collocation, form and aspect, colour strength and saturation ratio are also undesirable.
In addition, pitch is to the susceptibility height of temperature, and because of intensity and rigidity reduction, easily soften and the generation rut on the road surface during high temperature, bulge, phenomenons such as bellding, and relatively poor because of crack resistance when low temperature, the road surface easily produces fatigue cracking, shrinkage cracking, infringements such as reflective crack cause the road surface sharply to be damaged, and have influenced the weather resistance of bituminous pavement.
In sum, colored road surface not only can be beautified the environment, and make people's mood happy, in high spirits, and the road pavement traffic has favorable tissue and control action kou.In addition, rational color also plays positive regulating effect to the psychology and the mood of navigating mate.At present, pavior is mainly cement and pitch, and pitch is higher to the decolouring processing requirements, and the decolouring back is undesirable with other pigment arranging effects, uneconomical practicality, thereby the road surface dull coloring is dull at present, can't produce above-mentioned active effect; And because bituminous material itself to the susceptibility of temperature, causes the road surface high temperature laid is meltable, low temperature easily splits; Along with the raising of people's living standard, also more and more higher to the requirement of living environment, transportation condition, the colored road surface that making is bright and colourful can not only be beautified the environment, and can produce above-mentioned active effect; Thereby the needs that become a reality with the exploitation of pavior of colored road surface.
Summary of the invention the invention discloses a kind of colored road compound, mainly comprises agglutinate, pigment, gathers materials and other additive.The derivative or the mixture that wherein contain tall oil pitch, bathvillite, terebinth and these materials in the agglutinate, these resins are after treated oil is handled, and softening temperature reduces.Add rubber and plastics simultaneously as assistant agent, make this colored road stability be arranged preferably, and equally with traditional asphalt pavement mixture have a very strong effect of resistance to wearing and stable with compound; Simultaneously, the use of different pigment of can arranging in pairs or groups of this compound, thus make the road surface of laying present bright and colourful color.
The colored road of the present invention mainly comprises agglutinate, pigment, gathers materials and portions additive with compound; Wherein agglutinate mainly comprises tall oil pitch, bathvillite, terebinth and their derivative, also contains assistant agents such as rubber, plastics.Available pigment is mainly mineral dye, as titanium dioxide (white), and chromic oxide (green), ferric oxide (redness) etc.Gather materials and to choose according to the standard that pitch gathers materials, can select lime or china clay to do to gather materials.
Tall oil pitch, bathvillite, terebinth and their derivative all are very practical agglutinates, its derivative has dipolymer, oligopolymer or superpolymer, or monovalence or polyvalent alcohol ester, for example: front three propyl alcohol, glycerol or tetramethylolmethane; This derivative also can be resin metallic salt such as zinc, calcium and magnesium.The agglutinate that adopts among the present invention can be in the above-mentioned resin any or several mixtures, derivative or with the mixture of other resins.
In order to make the road surface firm and high resilience also will be added treated oil in the resin, handle through softening, to reduce the softening temperature of these resins.Treated oil can be chosen wantonly, as mineral oil, and vegetables oil, pine tar or their derivative.The processing oil viscosity is determined by particular case, allows to change in the scope of 15Pa.s～220Pa.s, is preferably within 32Pa.s～220Pa.s scope.The about 220Pa.s of mineral oil viscosity is suitable for general road.The vegetables oil dropping point is low, and stronger winter resistance is arranged, and is suitable for the low temperature site construction.
If will improve the winter resistance of this compound, effective means is to add rubber in agglutinate, and any synthetic chloroprene rubber can reach this purpose, as styrene-butadiene rubber(SBR); In agglutinate, add the appropriate thermal thermoplastic plastic, can reduce the thermal response of road surface compound, thereby can avoid by freezing and breaking that hot melt causes.The appropriate thermal thermoplastic plastic is can be at the multi-olefin compound of preset temperature fusing, for example polyethylene, polypropylene, ethylene-vinyl acetate copolymer, polymeric amide and polyester etc.Therefore, make this road good performance be arranged, should in agglutinate, add an amount of thermoplastics and rubber simultaneously, thereby make product have good winter resistance and higher softening temperature with compound.
