Description
Technical field
The present invention relates to a kind of modified pitch, and in particular to a kind of tyre powder-modified pitch and preparation method thereof.
Background technique
Waste tire powder-modified asphalt is the dispersing agent using pitch as waste tire powder, by the waste tire powder of high dose
With matrix pitch it is miscible under the high temperature conditions made of a kind of modified pitch.The incorporation of waste tire powder improves the height of pitch
Warm nature energy, elastic property and anti-aging property improve the pavement performance index of pitch: for example can be improved road wearability and
Cold resistance, prolonging service life of pavement, and shorten brake distance.On the other hand, waste tire powder is largely used to highway work
Cheng Zhong can effectively solve the problems, such as extensive waste tire bring noxious waste pollution, can also reduce noise, and waste and old
Tyre powder-modified pitch is low in cost with respect to other modified pitch, can reduce cost of building the road, and has significant environmental benefit and society
It can economic benefit.
Complex process, the higher cost of existing waste tire powder-modified asphalt, energy consumption is very big, and production cost is expensive.
It is first to be dissolved waste tire powder with solvent, then doped matrix pitch is through height that waste tire powder-modified asphalt, which produces another technique,
Waste tire powder-modified asphalt is made in speed stirring shearing, this technique is a large amount of organic because using during preparing modified pitch
Solvent, and these dissolutions are mostly carcinogenicity toxic and volatile aromatic hydrocarbon substance, can largely be escaped in production, use, and work is damaged
People's physical and mental health pollution of ecological environment.
Therefore, there are complex process, higher cost, energy for the production method of waste tire powder-modified asphalt in the prior art
Consume very big, production cost is expensive, there are the evolution of pernicious gas, pollute air, result in waste of resources the shortcomings that.
Summary of the invention
The object of the present invention is to provide a kind of tyre powder-modified pitches and preparation method thereof.The invention has technique letter
Single, at low cost, the advantages of energy consumption is small, energy-saving and emission-reduction.
Technical solution of the present invention: a kind of tyre powder-modified pitch, according to poidometer, by 50~70 parts of matrix pitch, wheel
20~30 parts of tire powder, 0.2~0.4 part of organic amine, 0.2~0.4 part of catalyst, 15~35 parts of rubber powder, thermoplastic resin 3~5
Part, 10~14 parts of emulsifier, 3~5 parts of stabilizer compositions.
Tyre powder-modified pitch above-mentioned, according to poidometer, by 60 parts of matrix pitch, 25 parts of tyre talc, organic amine 0.3
Part, 0.3 part of catalyst, 20 parts of rubber powder, 4 parts of thermoplastic resin, 12 parts of emulsifier, 4 parts of stabilizer compositions.
Tyre powder-modified pitch above-mentioned and preparation method thereof, includes following steps:
A, tyre talc is added after mixing organic amine and catalyst according to the ratio of 1:1, stirred in blender 20~30min,
A product are made；
B, A product obtained are added in hybrid heater, the matrix pitch, thermoplastic resin and stabilization of above-mentioned poidometer is added
Agent continuously stirs 40~30min of heating, and the rubber powder and emulsifier for adding above-mentioned poidometer are mixed, it is heated to 160~
180 DEG C to get.
Tyre powder-modified pitch above-mentioned, the organic amine are diphenylguanidine.
Tyre powder-modified pitch above-mentioned, the catalyst are stannous chloride.
Tyre powder-modified pitch above-mentioned, the activator are regeneration softening oil.
Beneficial effects of the present invention: compared with prior art, the invention has the following advantages that
After the present invention is modified waste tire powder using organic amine, catalyst, activator, rubber powder can be increased and be uniformly dispersed
Property and interface binding power, the modified composite asphalt of waste tire powder obtained be substantially reduced relative to matrix pitch needle penetration, it is soft
Change point to improve, modified pitch has better stability and low-temperature cracking-resistance than matrix pitch, and storage stability significantly improves；By
It is low in production temperature, in production or work progress, it not will cause the evolution of toxic gas, it is environmentally protective；Waste tire powder
The production technology of modified pitch is substituted by simple pure stirring production technology, makes rubber powder under certain conditions by additive
It is directly thrown into the matrix pitch of thawing after surface-modified pretreatment, can sufficiently dissolve expansion merely through simple stirring
And rubber crumb modified asphalt is made, the process is realized without the strong external force factor such as high speed shear and colloid mill, thus
Greatly reduce the production cost of waste tire powder-modified asphalt.Therefore, the invention have simple process, at low cost, energy consumption is small,
The advantages of energy-saving and emission-reduction.
