Abstract
The invention relates to modified asphalt for waterproof coiled material and a preparation method of the modified asphalt. The modified asphalt comprises, by weight, 50-60 parts of petroleum asphalt, 5-8 parts of softener, 5-8 parts of SBS modifier, 1-5 parts of stabilizer and 2-30 parts of filler, wherein the softener is polyethylene glycol, glycerol, pentaerythritol oleate or pentaerythritol acrylic ester. The invention further comprises a preparation method of the modified asphalt for the waterproof coiled material. The modified asphalt and the preparation method thereof have the advantages that the low-temperature flexibility stability and aging resistance of the modified asphalt prepared by the novel softener are greatly increased as compared with those of modified asphalt prepared by the petroleum hydrocarbon softener, and the preparation method is simple in step, low in production investment and evident in economic and social benefits.
Description
Technical field
The present invention relates to a kind of modified pitch and preparation method thereof, be specifically related to a kind of modified pitch for waterproof roll
And preparation method thereof.
Background technology
Since 20th century the mid-80s, along with the high speed development of China's capital construction, modified pitch is prevented by capital construction
The demand of water material is increasing, and the requirement to waterproof roll is more and more higher.Wherein, polymer modified asphalt has been used
Become the effective way improving Colophonium low temperature flexibility, but its price is high, relatively costly.Accordingly, it would be desirable to preparing modified pitch
During add softening agent, improve the low temperature flexibility of modified pitch.
At present, existing domestic conventional modified pitch softening agent is petroleum hydrocarbon, such as, subtract third fractional oil, reclaims waste used oil,
Second line of distillation oil etc..In recent years, in modified asphalt waterproof coiled material, ready-made article is often gone out outside equal with inherent quality when factory testing
It is up to state standards, but through after a period of time, analysis oil phenomenon, such as coiled material surface yellowing or formae oxydatae occurs in coiled material, from
And causing the low temperature flexibility performance of coiled material defective, life of product reduces；Preparing complexity, production cost is high simultaneously.Therefore, exploitation
It is a kind of that to have the low temperature flexibility performance of high stability, good ageing-resistant performance and the modified pitch in longer service life anti-
Water coiled material, the lifting to waterproof roll is significant.
Summary of the invention
The technical problem to be solved is to provide a kind of has the low temperature flexibility performance of high stability, good
The modified pitch for waterproof roll in ageing-resistant performance and longer service life and preparation method thereof.
The present invention solves its technical problem and employed technical scheme comprise that, a kind of modified pitch for waterproof roll, by with
The component composition of lower parts by weight:
Wherein, described softening agent is Polyethylene Glycol, glycerol, PETO or pentaerythritol acrylate.
Further, the described modified pitch for waterproof roll, it is made up of the component of following parts by weight:
Further, the described modified pitch for waterproof roll, it is made up of the component of following parts by weight:
Further, described asphalt is label 70# or 90# matrix pitch.
Further, described stabilizer is polymer monoene hydro carbons.
Further, described polymer monoene hydro carbons is polypropylene.
Further, described filler is Pulvis Talci.
The present invention solves its technical problem further and employed technical scheme comprise that, a kind of modified pitch for waterproof roll
Preparation method, asphalt and softening agent are stirred and are warming up to 160～170 DEG C, be subsequently adding SBS modifier, stabilizer, and
Mix 2～3 hours under 1000～2000rpm/min rotating speeds, be subsequently adding filler, stir 50～70min,.
The present invention uses the modified pitch for waterproof roll that novel softening agent prepares, and storing, low temperature flexibility is steady
The modified pitch that qualitative and ageing-resistant performance is prepared compared with petroleum hydrocarbon softening agent is increased dramatically, and preparation process is simple, raw
Produce small investment, there is significant economic benefit and social benefit.
The mechanism of action of novel softening agent:
The network structure of SBS modified pitch is Polymer adsorption, a process of swelling generation inversion of phases.At modifying process
In novel softening agent and the SBS formation that well mixes mutually be wound around and reach network structure, effectively improve its stability, it is to avoid produce
A raw simply simple high temperature individual molecular dispersion, is then mixed into loose structure, the most after heated, causes intensity to reduce, viscous
Attached power is deteriorated, and aromatic naphtha therefrom separates out, and affects inherent quality and the presentation quality of coiled material.
The present invention compared with prior art has a feature highlighted below:
1, waterproof roll low temperature flexibility performance degradation of the present invention is slow, it is ensured that the service life of product.
2, coiled material outward appearance of the present invention does not haves yellowing, rust staining phenomenon.
3, coiled material of the present invention is in process of production, and the Waste oil fume of generation is less, more environmentally-friendly.
It is demonstrated experimentally that the former low temperature limit of waterproof roll prepared by the modified pitch of the present invention is 29.0 DEG C, after using 30 days
Low temperature limit up to-28.4 DEG C, heat ageing low temperature limit is up to-26.5 DEG C；Compare and replace with common petroleum hydro carbons softening agent
The former low temperature limit of modified asphalt waterproof coiled material prepared by same approach is 29.0 DEG C, the low temperature limit after using 30 days up to-
25.0 DEG C, heat ageing low temperature limit promotes notable in terms of low temperature flexibility storage stability up to-17.4 DEG C.
