Colored road surface agglutinate and preparation method thereof
The invention belongs to a kind of building the road and use organic binder, is about the preparation method of colored road surface with agglutinate.
The colored road surface operating technique for beautifying the environment, promotes the security control of traffic engineering, and active effect is arranged.This operating technique obtains more general application in each developed country at present.Practice shows, the dark asphalt of the usefulness of in the past building the road because its solid colour belongs to chocolate, in the construction of road surface colorize, has a strong impact on the color development effect of colored road surface.For this reason each developed country with petroleum resin etc. be material development the more shallow colored road surface of many solid colours with agglutinate (to call color shop agglutinate in the following text).Day disclosure is held Xu Zhao 58-183759 and has been introduced with (1) petroleum resin or coumarone resin 20-50w%, with (2) 100 ℃ of kinematic viscosity be 10
-5~6 * 10
-5m
2The lubricating oil health aldehyde of/s or phenol treating are extracted oil 40~70w% out, and (3) SBR(styrene-butadiene rubber(SBR)) latex 1-5w%(concentration is about 45~75%) prepare color method of spreading agglutinate.The clear 62-21031 of Japan's special permission communique has introduced again with the petroleum resin of maleation or the coumarone resin of maleation in addition, the petroleum resin or the coumarone resin material 30~75w% that perhaps contain these maleation resins, with alkanes lubricating oil distillate 20~65w%, and high boiling point aromatic hydrocarbons 5~20w% prepares the method for softening temperature at 30~60 ℃ of color shop agglutinates.
Because all not fine colloidal structure that solves as the agglutinate of building the road of above-mentioned two kinds of methods constitutes, the feasible agglutinate of preparation thus, use propertieies such as high and low temperature stability, wear resistant are not good enough, pavement destruction phenomenons such as the road surface of institute's making produces too early and peels off, cracking.
Task of the present invention provides a kind of temperature sensibility, the coloured silk shop agglutinate that use propertieies such as wear resistant are good.To prolong colored road surface work-ing life, improve the colored road surface result of use.
According to the present invention, the preparation of color shop agglutinate is to be that mixed converting formed after 80~120 ℃ petroleum resin and SBS extracted oily heating plasticizing out with 360~560 ℃ lube oil finishing respectively with softening temperature.This color shop agglutinate constitutes:
Softening temperature is 80~120 ℃ of petroleum resin 35~45w%
Oil 40~55w% is extracted in 360~560 ℃ of lube oil finishings out
SBS(butylbenzene thermoplastic elastomer) 8~20w%
Preparation technology of the present invention is that after a part of lube oil finishing extraction oil was mixed thoroughly with SBS normal temperature, under 110~140 ℃ of conditions, intermittently stir about was 1~5 hour, makes homogeneous system A; After the lube oil finishing of remainder extracted out oil and mix thoroughly with petroleum resin normal temperature, stir about 1~5 hour intermittently under 100~130 ℃ of conditions was made homogeneous system B.Again A and B are evenly promptly got color shop agglutinate 100~130 ℃ of mixed down converting.
The solid colour of color shop agglutinate, be the coefficient result of chromaticity character of above-mentioned constituent material, therefore, according to the present invention, for guaranteeing that agglutinate has more shallow solid colour, the petroleum resin softening temperature is controlled at 80~120 ℃, extracts oil out as the lube oil finishing of softening agent, and its boiling range is controlled at 360~560 ℃.In addition, the SBS material with line style YH792 for well.In the agglutinate technology of preparing of in the past coloured silk shop, with petroleum resin and be used for it is carried out the material of modification, mainly be styrene-butadiene rubber(SBR) (SBR) and styrene-butadiene latex.Because in the agglutinate preparation process, the mixed of this class material converted, the plasticizing complicated operation, numerous rope has limited and has mixed the raising of the amount of converting, thereby made in the colloidal structure of agglutinate, and modification component shortcoming does not have modifying function.The present invention confirms in the colloid of agglutinate constitutes that according to systematic study the effectively mixed amount of converting of SBS should be 8~20w%.In this scope, the present invention has realized the improvement in performance to the color shop of tree oil lipid agglutinate.
Because the present invention selects rationally to make that agglutinate product solid colour is more shallow to material and material mixture ratio, the colloidal structure ideal, the visco-elasticity temperature range is wide, and use propertieies such as temperature sensibility, abrasion performance are good.Compare with the heavy traffic flow road bitumen, color shop of the present invention agglutinate, use properties is better than heavy duty road asphalt, is a kind of high temperature performance excellent agglutinate of building the road of holding concurrently, and this conclusion has been broken the final conclusion that the agglutinate high and low temperature performance of in the past building the road is difficult to take into account.The color shop of the present invention agglutinate concrete sample color development effect is suitable with stadiums plastic floor material.
Because the present invention has selected for use SBS as the modification component, and colloidal structure is tending towards rationally, and preparation technology's temperature is reduced, slowed down the detrimentally affect that solid colour is deepened because of the material thermal degradation when.
Embodiment 1

2,15w% SBS(butylbenzene thermoplastic elastomer)
3, oily 47w% is extracted in 360-460 ℃ of lube oil finishing out
(2) preparation technology
Extract lube oil finishing 2/3 of oil out, after normal temperature is mixed thoroughly with SBS down, under 130 ℃ of conditions intermittence stir about 3 hours, make homogeneous phase A; With 1/3 lube oil finishing of remainder extract out oil and petroleum resin normal temperature mix convert after, stir about 2 hours intermittently under 120 ℃ of conditions is made homogeneous phase B.Under 120 ℃ of conditions, A and mixed the converting of B are evenly promptly got the purpose product.
(3) test result
As shown in table 1, the color shop of the present invention agglutinate softening temperature is higher, and brittle point is lower, and viscoelastic attitude temperature range is obviously greater than the clear 62-21031 of Japan's special permission communique.By table 2 as seen, compare with heavy duty road asphalt, the color shop of the present invention agglutinate has very high stability under 60 ℃ of high temperature; Under-25 ℃ of low temperature bigger deformability is arranged again, the high temperature performance tool is good.
