Description
Technical field
The present invention relates to waterproof roll technical fields, refer specifically to a kind of microparticle modified pitch.
Background technique
Pitch has waterproofness and anticorrosive property, is widely used today as pavement material and covering material of road etc..But
It is that China's road asphalt specific gravity is typically small, paraffin content is higher, ductility is smaller, softening point measurement value is higher, but thermal stability
Bad, brittle point is poor compared with high and low temperature cracking resistance.Generally existing poor high temperature stability, cold cracking are serious, durability is bad etc. asks
Topic.Therefore conventional pitch is no longer satisfied the requirement of high-strength, safe and stable, the resistance to service performance of waiting so long of bituminous pavement, together
When, the high-quality heavy oil asphalt of import and modified pitch are again very expensive.It must be pocessed to improve the service performance of pitch.
Modifying agent is dissolved or dispersed in pitch, is improved or is improved the pavement performance of pitch, reduce the various diseases of bituminous pavement, prolong
The service life of long the inside.The problem of conventional particles modifying agent, disadvantage was as follows: needing colloid mill during mechanical action, takes rate
Energy consumption.Oxidization time is long, and >=2 hours.The temperature needed is excessively high, and there are more undissolved solids between 200-230 DEG C.It is soft
Changing point is 61 DEG C.Low-temperature resistance is at -20 DEG C.
Summary of the invention
The present invention is insufficient according to prior art, proposes a kind of microparticle modified pitch, fusing time 30 minutes, divides
It is good to dissipate property, dissolution is thorough, improves efficiency, and improves quality guarantee, and temperature production is environmentally protective, saves electric energy cost.
In order to solve the above-mentioned technical problem, the technical solution of the present invention is as follows:
A kind of microparticle modified pitch, by weight component include: 20-40 parts of pitch, 30-34 parts of naphthenic oil, scrap rubber
Grain 10.5 parts, 1 part of WH-0330 microparticle modifying agent, 26.5 parts of mountain flour.
Preferably, the WH-0330 microparticle modifying agent includes polypropylene bulk material 70%, polyethylene raw material 25%
With stabilizer 5%.
Preferably, the WH-0330 microparticle modifying agent is powdered no more than 10 mesh.
Preferably, the quality that the WH-0330 microparticle modifying agent is added is the 3%-4% that asphalt quality is added.
Preferably, the quality that the WH-0330 microparticle modifying agent is added is the 1.5%-2% that asphalt quality is added.
The present invention have the characteristics that it is following and the utility model has the advantages that
By adopting the above technical scheme, mechanical energy consumption is not necessarily to colloid mill, saves fund and energy consumption；Oxidization time is short ,≤
40min；Temperature is low compared with conventional particles, at 190 DEG C；The present invention can be completely dissolved；Softening point is higher, at 120 DEG C；Low-temperature resistance mark
Standard is at -25 DEG C.
Specific embodiment
Specific embodiments of the present invention will be further explained below.It should be noted that for these implementations
The explanation of mode is used to help understand the present invention, but and does not constitute a limitation of the invention.In addition, invention described below
Technical characteristic involved in each embodiment can be combined with each other as long as they do not conflict with each other.
Embodiment 1
The present invention provides a kind of microparticle modified pitch, and component by weight includes: 20-40 parts of pitch, naphthenic oil 30-34
Part, 10.5 parts of waste rubber grain, 1 part of WH-0330 microparticle modifying agent, 26.5 parts of mountain flour.
Further, the WH-0330 microparticle modifying agent includes polypropylene bulk material 70%, polyethylene raw material 25%
With stabilizer 5%.The WH-0330 microparticle modifying agent is powdered no more than 10 mesh.
Table 1
| Common PP asphalt modification particle | Microparticle asphalt modifier | |
| Temperature | 210℃ | 185℃ |
| Thawing time | 2-3h | 20-30min |
| Softening point | 95-100 | 110-120 |
| Compatibility | Cooling is easy to crack | It is not easy to crack |
Table 1 adds microparticle asphalt modifier and adds the Experimental Comparison of common PP asphalt modification particle.
By test result it is found that addition microparticle asphalt modifier melt temperature is lower, 210 DEG C only need to be reached i.e.
Can, and the thawing time greatly shortens, and only needs 20-30min, substantially increases the efficiency of asphalt melting, and good dispersion, and it is molten
Solution is thorough.In addition, the softening point of pitch up to 110-120 DEG C, substantially increases quality guarantee, and not easy to crack, improve
Service life greatly reduces maintenance cost.
Embodiment 2
The present embodiment the difference from embodiment 1 is that, be added the WH-0330 microparticle modifying agent quality be added drip
The 3%-4% of green quality.According to actual needs, it is used as warm modifying agent.WH-0330 microparticle asphalt modifier only needs simply
Mechanical stirring is stably dispersed in pitch, can also be directly thrown to mixture and be mixed in cylinder.
Embodiment 3
The present embodiment the difference from embodiment 1 is that, be added the WH-0330 microparticle modifying agent quality be added drip
The 1.5%-2% of green quality.According to actual needs, it is only used as warm-mixing agent.
Above the embodiments of the present invention are described in detail, but the present invention is not limited to described embodiments.It is right
It include portion to these embodiments in the case where not departing from the principle of the invention and spirit for those skilled in the art
Part carries out a variety of change, modification, replacement and modification, still falls in protection scope of the present invention.
