Abstract
The invention discloses a high-polymer warm-mixed asphalt mixture toughening modifier, which relates to the technical field of composite materials, and specifically relates to a high-polymer warm-mixed asphalt mixture toughening modifier. The high-polymer warm-mixed asphalt mixture toughening modifier is prepared through mixing modified butadiene styrene rubber (30-60%) with modified polyethylene resin (5-20%) in a certain proportion, uniformly mixing the obtained mixture with hydrocarbon resin (10-40%) and aromatic oil (10-30%) in proportion, and extruding the obtained product by using a double-screw extruder. Through mixing the modified butadiene styrene rubber with other polymer materials, the butadiene styrene rubber is preliminarily stretched, so that the mixing temperature of an asphalt mixture is reduced; and through cooperating with the combined action of other auxiliaries, an effect of improving the application performance of asphalt is achieved, thereby saving energy, prolonging the service life of an asphalt pavement, and reducing the maintenance cost.
Description
Technical field:
The present invention relates to technical field of composite materials, be specifically related to superpolymer Warm-Mix Bitumen Mixture plasticized modifier.
Background technology:
Existing Warm-Mix Bitumen Mixture properties-correcting agent mainly is in pitch, to add lower molecular weight matter part, the flowability of adding auxiliary agent increase matrix pitches such as stablizer again.Because lower molecular weight matter part is reduced bituminous viscosity, the cohesive force of asphalt can not be provided, the performance of asphalt is weakened.Make the cost that mixes and stirs of bituminous pavement reduce, but maintenance cost increase the reduction in work-ing life.
The asphalt mixture warm-mixing technology is a kind of novel environment friendly pavement technique of high energy-conservation low emission, mixes and stirs in the process because the reduction of temperature, and the discharging of glance coal reduces more than 80%, has reduced the pollution of environment and the infringement of workmen's health.Improve working efficiency, alleviated the high temperature ageing when pitch mixes and stirs, increased the work-ing life of bituminous pavement.
Nineteen ninety-five has at first adopted the temperature of asphalt to mix technology in Europe, what present domestic applied research was more is that the organic additive temperature is mixed technology.The subject matter that exists is to compare hot-mix asphalt mixture, the increase expense because having increased warm-mixing additive, and the poor-performing of Warm-Mix Bitumen Mixture, especially low-temperature performance.
Summary of the invention:
The purpose of this invention is to provide superpolymer Warm-Mix Bitumen Mixture plasticized modifier; It through with after the styrene-butadiene rubber(SBR) modification with other macromolecular material blend, make styrene-butadiene rubber(SBR) tentatively unfold, reduce the temperature of mixing and stirring of asphalt; And cooperate other auxiliary agent actings in conjunction; Reach improvement, save the energy and prolong bituminous pavement work-ing life simultaneously, reduce maintenance cost the pitch use properties.
In order to solve the existing problem of background technology; The present invention adopts following technical scheme: the polyvinyl resin that it processes back 5%-20% with styrene-butadiene rubber(SBR) and the modification of modification processing back 30%-60% is mixed with certain proportion and is joined; Mix in proportion with the hydrocarbon resin of 10%-40% and the aromatic hydrocarbon oil of 10%-30% again, extrude by the duplex forcing machine.
Described duplex forcing machine is formed by three sections: first section near loading hopper, is feeding section, and its function lets material with a forcing machine of speed entering relatively stably; Second section is divided into the compression section, forms melt and pressure increase in this section; The 3rd section is divided into metering zone, nestles up outlet of extruder; At the afterbody of machine barrel, plastic melt leaves forcing machine through a head, and the melt-flow of extruding is here passed through, and the speed of rotation of screw rod is determining the output of forcing machine.
Described styrene-butadiene rubber(SBR) is white or little yellow porous small-particle or column, and particle diameter is generally 3～4.5*4～9mm, is the toughner of hard brittle materials such as plastics, pitch.
A kind of thermoplastic resin that described polyvinyl resin ethene makes through polymerization.In industry, also comprise the multipolymer of ethene and a small amount of terminal olefin.The Vilaterm odorless, nontoxic, the feel ceraceous; Have good resistance to low temperature (minimum use temperature can reach-70～-100 ℃), chemicalstability is good, the erosion of the most of soda acids of ability (not anti-acid with oxidizing property); Be insoluble to common solvent under the normal temperature, water-absorbent is little, and electrical insulation capability is excellent.
Described hydrocarbon resin is a kind of thermoplastic resin, and its ingredient all is a hydrocarbon polymer, so be referred to as hydrocarbon resin.Because cheap, advantages such as compatibility good, fusing point is low, water-fast, anti-ethanol and chemical that it has can be widely used in multiple industry and fields such as rubber, tackiness agent, coating, papermaking, printing ink.
Described said aromatic hydrocarbon oil be crude oil behind high temperature underpressure distillation separation of lighter oil content, in addition the auxiliary material modulation forms.This product has good rubber compatibility, and characteristics such as high temperature resistant, low volatilization can significantly be improved the processing characteristics of rubber, weathering resistance, oxidation, friction, aging degree that can the Reinforced Rubber product.
The present invention through with after the styrene-butadiene rubber(SBR) modification with other macromolecular material blend; Make styrene-butadiene rubber(SBR) tentatively unfold; Reduce the temperature of mixing and stirring of asphalt, and cooperate other auxiliary agent actings in conjunction, reach improvement the pitch use properties; Save the energy and prolong bituminous pavement work-ing life simultaneously, reduce maintenance cost.
