The beneficial effects of the invention are as follows：
The purpose of the present invention is that the waste and scrap after being disassembled using motor vehicle liquidation prepares a kind of modified pitch new material, is solved
The problem of part can not be recycled after automobile dismounting.The modified pitch new material that the present invention is obtained has the characteristics that：
1st, the road life of modified asphalt material.
2nd, the Rut resistance of modified asphalt material, cold-check resistance can strengthen, and substantially, pavement performance is superior for function.
3rd, process for preparing modified asphalt saves resource, and cost is greatly lowered, non-environmental-pollution, environmental protection.
4th, process for preparing modified asphalt effectively solves the not recovering discarded material produced during motor vehicle liquidation is disassembled
Use problem, efficent use of resources turns waste into wealth, and improves Social benefit and economic benefit.
The present invention also provides a kind of rational utilization method for handling the not recyclable material after automobile dismounting, can only lead to
Cross such as ceiling pad cotton, fiber, slipmat, abatvoix, flame-retarded resin felt, PET blankets and the rubber-like of directly burning processing
Material is prepared into a kind of modified pitch, meets road engineering code requirement, shows good pavement performance, solves automobile dismounting
What is produced can not the discarded object that utilizes of secondary recovery.Simultaneously while existing pitch every road index is changed, it is to avoid pair
The problem of environmental pollution and the wasting of resources that the existing processing method of discarded object is brought, add social output and social benefit.
Embodiment
A kind of modified asphalt material of the present invention, including automobile dismounting not recyclable material and 93~97 in terms of parts by weight
The SBS modified pitch of parts by weight.
Described SBS modified pitch, including following components in terms of parts by weight：The parts by weight of matrix pitch (90#) 90~91,
The parts by weight of SBS modifier 1~3.6, the parts by weight of stabilizer 0.4, the parts by weight of cosolvent 1.6~2.Matrix pitch is preheated to 180
~185 DEG C, SBS modifier, stabilizer are added, the agitated rear acquisition SBS of cosolvent is added after grinding under lasting stirring
Modified pitch.
Recyclable material can not individually select materials A to described automobile dismounting, can individually select material B, can also
Select materials A and two kinds of material B mixture.
By automobile dismounting, recyclable material is not divided into two classes, and a class is materials A, and materials A is 1~5 parts by weight, selected from automobile
One or more in ceiling, automobile trunk, automobile door plate.This kind of material is to play the glass of sound isolating and flame-retardant in automotive trim
Glass fiber-like material, polyurethane class material, the material of this part have that stronger wearability, intensity be high, corrosion-resistant, toughness
It is good, fire-retardant.
Another kind of is material B, and material B is 2~4 parts by weight, selected from fascia, vehicle steering, automobile rubber pin
One or more in pad.This kind of material is the rigid plastics rubber type of material shielded in automotive trim, material molecule
Amount is big, and anti-high and low-temp performance is strong.Due to using automobile dismounting not recyclable material so that modified asphalt material of the invention
Rut resistance, the freeze proof ability of splitting be remarkably reinforced, while its road is obviously prolonged with the life-span, pavement performance is more superior.
A kind of preparation method of above-mentioned modified asphalt material, comprises the following steps：
Step 1: SBS modified pitch is preheated into 180~185 DEG C；
Step 2: by automobile dismounting, recyclable material is not crushed to 40~60 mesh；
Step 3: step 2 products therefrom is well mixed with step one products therefrom；
Step 4: persistently stirring 2~4h, modified asphalt material is obtained.
In above-mentioned preparation process, described automobile dismounting not one kind in materials A and material B of recyclable material or
Two kinds.Materials A and material B both materials can be added separately in SBS modified pitch, and SBS is added to after can also mixing
In modified pitch, because the performance of both materials is different, while being used in mixed way best results.Materials A and material B are added simultaneously
Into SBS modified pitch, because automobile dismounting not recyclable material itself characteristic (wear-resisting, intensity is high, corrosion-resistant, good toughness, resistance
Combustion, molecular weight are big, and anti-high and low-temp performance is strong), the modified asphalt material obtained have Rut resistance, it is freeze proof split, fire-retardant, increase road
The features such as using the life-span.
Present invention also offers a kind of rational utilization method of automobile dismounting not recyclable material, comprise the following steps：
Step 1: by automobile dismounting, recyclable material is not crushed to 40~60 mesh；The not recyclable material of described automobile dismounting
The selection of material is same as above.
Step 2: the matrix pitch of 90~91 parts by weight is preheated into 180~185 DEG C, adds 1~3.6 parts by weight SBS and change
Property agent, 0.4 parts by weight stabilizer, add 1.6~2 parts by weight cosolvents under lasting stirring after grinding, it is broken after vapour
Car disassembles not recyclable material, stirs 10min.
Step 3: blend obtained by step 2 is squeezed into finished pot, then add into finished pot 0.4 parts by weight stabilizer,
2~4h is persistently stirred under the conditions of 180 DEG C, modified asphalt material is obtained.
The material that can not be recycled after being disassembled for motor vehicle liquidation, can only be handled by burning, and pollute environment, cost
It is higher.This portion of material is added in SBS modified pitch in the present invention new modified asphalt material is made, applied in road engineering
In, meet《JTG F40-2004 standard specification for construction and acceptance of highway asphalt pavement》Standard requirement, what solution automobile dismounting was produced can not
The processing of the secondary discarded object utilized, while existing SBS modified pitch every road index is changed, it is to avoid torn open to automobile
The problem of solution environmental pollution and the wasting of resources that the existing processing method of recyclable material is not brought, add economic output and society
Can benefit.
