Abstract
The invention discloses a waste and old rubber powder modified bituminous material with low temperature resistance and crack resistance for a waterproof coiled material. The material is prepared by the following raw materials in parts by weight: 40-60 parts of asphalt, 10-15 parts of waste and old tyre rubber powder of 100-200 mesh sieve, 5-10 parts of an EVA emulsion whose solid content is 30-40%, 3-5 parts of natural rubber latex whose solid content is 30-40%, 1-1.5 parts of polysorbate-80, 0.5-1 part of a calcium chloride aqueous solution whose mass content is 0.5-1%, 5-10 parts of talcum powder, 3-5 parts of epoxidized soybean oil, and 0.3-0.5 parts of barium stearate. The rubber powder modified bituminous material for the waterproof coiled material has the advantages of uniformity, high stability, good durability, good low temperature resistance without easy cracking and deformation, low price, long usage life, and economy and practicality.
Description
Technical field
The present invention relates to modified asphalt technology field, more particularly to a kind of modified waterproof volume of low temperature resistant cracking resistance waste rubber powder
Timber-used asphalt material and preparation method thereof.
Background technology
With developing rapidly for Domestic Automotive Industry, it is consequently increased as the junked tire quantity of solid waste, is turned into
Great environmental issue of concern.At present, the main application fields of junked tire are the production of modified pitch.By junked tire
It is processed into rubber powder and mixes in pitch for building highway and production waterproof material, can both improves the usability of pitch
Can, junked tire can be made to turn waste into wealth again, environmental issue is solved, achieve many things at one stroke.
Document《Waste rubber powder modified asphalt mechanism of modification and its performance study》Described in, shoddy is by chemically or mechanically
Process and be made, its surface is made up of the network-side of the spatial network being destroyed, its surface is in irregular burr shape and cloth
Completely surround and watch crackle.Simultaneously as in the process of rubber powder modified asphalt material, without formation between rubber powder and pitch
Uniform system, structure is more loose, is susceptible to cracking, influences the durability of material.Document《Silane coupler is dripped to rubber
The influence of blue or green performance》The rubber powder processed using silane coupler is modified to pitch, improves rubber powder modified asphalt material
The compatibility and stability of material.However, this method does not improve the surface texture of shoddy, to modified asphalt material performance
Improve limited, while silane coupler is higher as raw material application cost, it is necessary to make improvements.
The content of the invention
The object of the invention is exactly to make up the defect of prior art, there is provided a kind of cheap, homogeneous, stability is high,
Good endurance, modified waterproof roll asphalt material of low temperature resistant cracking resistance waste rubber powder of long service life and preparation method thereof.
The present invention is achieved by the following technical solutions：
A kind of modified waterproof roll asphalt material of low temperature resistant cracking resistance waste rubber powder, it is by the raw material system of following weight parts
：
Pitch 40-60,100-200 mesh rubber powder of waste tire 10-15, solid content is the EVA emulsion 5-10 of 30-40%, solid content
It is the natural rubber latex 3-5 of 30-40%, Tween-80 1-1.5, mass concentration is the calcium chloride water of 0.5-1%
0.5-1, talcum powder 5-10, epoxidized soybean oil 3-5, barium stearate 0.3-0.5.
A kind of preparation method of the modified waterproof roll asphalt material of low temperature resistant cracking resistance waste rubber powder, including following step
Suddenly：
（1）Rubber powder of waste tire is compared 1 through microwave activation surface is modified by solid-liquid weight:10-1:20 mix with water after plus
Enter Tween-80, EVA emulsions, natural rubber latex high-speed stirred uniform, be subsequently adding calcium chloride water flocculation, will wad a quilt with cotton
Condensate is dried, grinding is uniform, obtains modified rubber powder；
（2）150-160 DEG C will be to slowly warm up to after pitch melting, dehydration, then sequentially adds epoxidized soybean oil, barium stearate,
It is slowly stirred uniformly, obtains mix asphalt matrix；
（3）By step（1）In modified rubber powder and remaining raw material add step jointly（2）In mix asphalt matrix in and in
175-195 DEG C of high-speed stirred 0.5-1h, obtains final product the modified waterproof roll asphalt material of low temperature resistant cracking resistance waste rubber powder after cooling.
It is an advantage of the invention that：
The present invention is mixed waste rubber powder through microwave activation surface is modified with EVA emulsions, natural rubber latex first,
Then be co-precipitated it by flocculation, and be dried, milled processed, crackle, network-side to the surface of waste rubber powder rise
To combine, filling effect, reduce the space between waste rubber powder and pitch matrix, formed between rubber powder and pitch compared with
It is uniform, close system, so that strengthen the compatibility and stability of system, after the compounding processing of remaining raw material, the rubber for obtaining
Rubber powder modified waterproof roll asphalt material has the characteristics of homogeneous, stability is high, good endurance, and resistance to low temperature good,
Not easy to crack, deformation, cheap, long service life is economical and practical.
