Abstract
The invention discloses an environmentally friendly bituminous pavement preventive maintenance regenerant formula and a preparation method thereof. The invention is realized by the following technical scheme: 1. the regenerant comprises component A and component B; the component A comprises the following components according to the parts by weight: 20-80 parts of waterborne epoxy emulsion, 1-200 parts of water, 1-15 parts of microsilica and 0.5-8 parts of talcum powder; the component B comprises waterborne epoxy curing agent and aromatic active agent, the waterborne epoxy curing agent is 80% of the waterborne epoxy emulsion in the component A by weight percent and the aromatic active agent is 70% of the curing agent by weight percent; 2. when using the regenerant, the component A and the component B are mixed mainly for bituminous pavement crack-filling and surface ultrathin layer spraying and curing. Compared with the prior art, the invention has the advantage that the adopted diluent is water, the regenerant contains low volatile organic solvent and the environmental performance is good.
Description
Technical field
The present invention relates to a kind of environment-friendly type bituminous pavement preventive maintenance regenerant prescription and preparation method thereof
Background technology
Along with development and national economy, municipal government, road management department and cities are more and more paid attention to the improvement of traffic environment.Strengthen dynamics of investment, strengthening motorway and urban infrastructure construction is the fundamental way that improves traffic environment.But under limited fund condition, how utilizing the advanced management notion, safeguard to Sustainable development the service level of existing road network, prolong the work-ing life on existing road surface, is the practical problems of pendulum in face of the scientific research personnel.
In the existing road, bituminous pavement occupies very big proportion.In the bituminous concrete pavement use, bituminous material is subjected to the effect of various natural causes (oxygen, light, heat and moisture) etc., and its physics and chemical property change, and the pitch hardening becomes fragile, with the cohesiveness variation of gathering materials, cause the road surface to produce destructions such as crack, loose, pitted skin.Pavement performance is decay thereupon also, and this variation of asphaltic nature is called " wearing out ".
For the aged bituminous material, if can make its chemical composition that " driving in the wrong direction " take place by adding regenerator, bituminous material returns to original character, and this method is bituminous regeneration, and pavement performance is restored thus.The regeneration of bituminous pavement can be saved a large amount of pitch and sandstone material, saves construction investment, prolongs road life, has remarkable economic efficiency and society, environmental benefit.
In the U.S.,,, formed a kind of idea that prolongs service life of road surface with the regeneration maintenance agent along with the proposition of preventive maintenance notion since the nineties.At present, external regeneration maintenance agent progressively enters China market.
Be that the early water infringement is all relevant with the size of voidage with the infringement that ageing of asphalt brings.For widely used antiskid top layer in the past, voidage is big more, and the damage by water evil is serious more, and bituminous is aging, and also Shaoxing opera is strong.More external developed countries are coated with as far back as the preventive maintenance technology-surface that has begun to carry out bituminous pavement the sixties in 20th century and rinse Study on Regeneration and exploitation.The U.S. as far back as nineteen sixty in the past development research come out to be used for military airfield, turned to civilianly by military in 1980, states such as Canada, Brazil adopted successively afterwards.In several South America and airport, North America, " regeneration of drop regeneration " and sandbox " drop " is used as regenerator and the protective layer of protecting asphalt pavement.China is then on probation in Kunming May calendar year 2001, and the Guangzhou also has unit to be coated with in the preventive maintenance technology-surface of 2001 pairs of this novel bituminous pavements to rinse drop regeneration having carried out tentative experiment.Calendar year 2001, the Yunnan Speedway Control Broad studied the performance that " drop regeneration " is applied on the road in Yunnan Province, studies show that " drop regeneration " can be used as a kind of maintaining method of bituminous pavement.For the bituminous concrete pavement that uses certain time limit, to be coated with and to rinse regenerator be to be that main component (30%-50%) synthetic eu-bitumen pavement recycling sealing agent seals the road surface by coal-tar pitch to the state's outside surface that adopts at present, stops under the moisture and ooze, and oxygenizement slows down.The problem of this material maximum the has been floating construction depth of asphalt surface greatly reduces cling property, influences the security service of road.This material has used a large amount of volatility petroleum solvents simultaneously, and is uneconomical, also not environmental protection.Along with people's environmental consciousness improves gradually, many countries have issued restriction volatile organic solvent (voc) environmental regulation, so regenerator hydrotropismsization direction develops into inevitable.
The present invention seeks to develop a kind of environment-friendly type bituminous pavement preventive maintenance regenerant, have stronger sticking power, stronger chemical resistance, and good environmental protection, VOC content is low.
Summary of the invention:
The present invention seeks to be achieved through the following technical solutions:

First component weight ratio, aqueous epoxy emulsion: 20～80
Water: 1～200;
Silicon powder 1～15;
Talcum powder 0.5～8.
Component B is that aqueous epoxy curing agent and aromatic series promoting agent are formed, wherein the aqueous epoxy curing agent part by weight be in the first component aqueous epoxy emulsion 80%, aromatic series promoting agent part by weight is 70% of a hardener dose.
2, a kind of environmental protection bituminous pavement preventive maintenance regenerant according to claim 1, it is characterized in that selected liquid-state epoxy resin is a water-based bisphenol A-type lower molecular weight liquid-state epoxy resin emulsion, selected waterborne curing agent is the epoxy of modified polyamide, the Water-borne modification of the modified fatty amine that is selected from Water-borne modification, Water-borne modification, in the polyamines affixture any one; Selected aromatics is one or more mixtures of coal tar, coal-tar pitch, aromatic hydrocarbon oil.
3, a kind of constructional method of environmental protection bituminous pavement preventive maintenance regenerant as claimed in claim 1, its feature is constructed in the suitable construction time limit behind the abundant mixing with electric blender in said components.Can adopt the mode of ultra-thin spraying, brushing or roller coat during scumbling, after the dilution, also can be used for asphalt pavement crack and fill up
4, a kind of making method of environmental protection bituminous pavement preventive maintenance regenerant as claimed in claim 1, it is characterized in that first component manufacture method is: with water, auxiliary agent and whole filler reduction of speed behind 1000～1800rpm high speed dispersion, 8～30min, again the liquid-state epoxy resin emulsion is mixed 5～15min with dispersion machine or stirrer under 200～600rpm speed, packing.Second component manufacture method is: aqueous epoxy curing agent is formed with the aromatic series promoting agent mixed 5～15min with dispersion machine or stirrer under 200～600rpm speed, packing.
