Abstract
The invention provides an asphalt reducing agent and a preparation method thereof, and relates to the technical field of asphalt, in particular to the asphalt reducing agent which is used for reducing aged asphalt and is good in reduction effect and the preparation method of the asphalt reducing agent. The asphalt reducing agent is characterized by being prepared by mixing, by mass, 20-30 parts of reducing agent base materials, 60-70 parts of 90# solvent oil and 10-15 parts of carboxy styrene-butadiene latex, wherein each part of the reducing agent base material comprises, by mass, 20-40 parts of kieselguhr, 40-50 parts of water-borne epoxy resin and 5-10 parts of waterborne polyurethane. According to the asphalt reducing agent and the preparation method thereof, aged asphalt paste on the surface layer of an asphalt pavement can be effectively updated and reduced; meanwhile, asphalt which is not subjected to aging is protected, the original feature is maintained, and the aging time is slowed down; compared with a traditional fog sealing layer, the asphalt reducing agent sealing layer mainly has the advantages that the asphalt aging action is activated, and the service time is prolonged.
Description
Technical field
The present invention relates to field of bitumen technology, especially one is used for reducing aged asphalt, and the good Colophonium of reduction effect is also
Former dose and preparation method thereof.
Background technology
Along with the fast development of China's communication, it is extremely to be necessary that built highway carries out preventive maintenance
's.The technology of Preventive maintenance for highway is the most, but one of Colophonium reducing agent technology the most most practical, maximally effective, can be extensively
The preventive maintenance being used in each standard highway on.This technology is when road surface occurs that aging, loose, crack, pit, water damage
During the local early diseases such as evil idea, Colophonium reducing agent is sprayed on bituminous paving, to recover the performance of asphalt pavement material, improves
Pavement Condition, delaying aging, in the effective service life extending bituminous paving, reduces the fare of life-span of highway.
Summary of the invention
To be solved by this invention is exactly to occur after existing bituminous paving life-time service catabiosis to reduce bituminous paving to make
By performance and the problem in life-span, it is provided that one is used for reducing aged asphalt, Colophonium reducing agent that reduction effect is good and preparation side thereof
Method.
Colophonium reducing agent of the present invention and preparation method thereof, it is characterised in that this reducing agent includes going back of 20～30 mass parts
Former dose of base material, 60～70 mass parts No. 90 solvent naphthas and the carboxylic styrene butadiene latex of 10～15 mass parts be mixed to prepare, wherein
Every part of reducing agent base material comprises 20～40 mass parts kieselguhr, 40～50 mass parts aqueous epoxy resins and 5～10 mass
Part aqueous polyurethane.

(1), prepare reducing agent base material: take 40～50 mass parts aqueous epoxy resins, add 20～40 mass parts kieselguhr and 5～
10 mass parts aqueous polyurethanes, obtain reducing agent base solution after mix is uniform；
(2), the reducing agent base solution that will obtain in step 1, take in the funnel that 20～30 mass parts pour high speed shear instrument into, beat
Drive the switch of high speed shear instrument, the most uniformly pour No. 90 solvent naphthas of 60～70 mass parts simultaneously into, shear time be 30s～
60s, then opens the flowing water Valve of funnel, collects and obtains semi-finished product；
(3), by step 2 being collected after the semi-finished product obtained are heated to 120 DEG C, the carboxylic styrene butadiene latex of 10～15 mass parts is added
Persistently mix, obtain Colophonium reducing agent.
Colophonium reducing agent of the present invention and preparation method thereof, technique is simple, easy to use, directly by the Colophonium for preparing also
Former dose is sprayed on asphalt roads, it is possible to effective renewal and reduction bituminous paving top layer have occurred and that aging asphalt cement
Body, protects the part Colophonium being not yet aging simultaneously so that it is " maintaining original performance, slow down ageing time ", the drip of the present invention
Blue or green reducing agent sealing is compared with tradition mist sealing, and main advantage is to activate aged asphalt effect, extends the use time.
