Application and description of environmental protection and high efficiency modified rubber powder

Research and description of environmental protection modified rubber powder

ONE, interpretation
Rubber modified asphalt is by vulcanized rubber powder and active agent, and other additives mixed plasticizing extruded modified rubber powder, the product maintains the rubber plastic refined from a new type of environmental protection material application modified asphalt high efficiency and tasteless. Reducing the VOCS emission such as sulfur dioxide and hydrogen sulfide produced in the production process of waterproof roll rubber modified asphalt and highway modified asphalt has a significant effect. This product is a kind of new material modified rubber powder for producing environmental protection type odourless rubber modified asphalt.

Two, rubber modified asphalt comparison

Three, product performance

1, the use of modified rubber powder, can reduce about 50% of carbon monoxide. Carbon dioxide and hydrogen sulfide and other VOCS emissions. At the same time, it can reduce the irritating smell produced by asphalt and modified rubber powder, and obviously improve the production environment and site construction environment of waterproof roll rubber modified asphalt and highway modified asphalt.
2. As an asphalt modifier, modified rubber powder has good plasticity, good weather resistance, strong wear resistance and is not easy to aging.
3, with good high temperature and low temperature resistance (rut, bag), improve impact resistance and resistance to cracking performance, have good compression ability, so that the elasticity and flexibility have been enhanced.
4. The use of modified rubber powder can be greatly increased to quickly swell, accelerate the fusion and cross-linking of rubber powder and asphalt, and improve the indicators of rubber modified asphalt. In the waterproof roll rubber modified asphalt, highway asphalt modified, modified rubber powder can partially or completely replace SBS modified.
Four, the advantage of modified rubber powder modified asphalt
1, anti-rutting, prolong the service life of road, improve the high and low temperature performance of pavement (high temperature softening, low temperature anti cracking), effectively reduce the reflection crack, the lower pavement maintenance, in not reduce pavement strength under the standard of the thickness of the pavement, compared with other polymers, cost savings, reduce the oil consumption, significantly reduce road noise (3 ~ 6 db), It is equivalent to reducing the traffic volume by half, shortening the braking distance, improving driving safety, reducing water fog and reflective road surface, making the road surface darker and improving driving comfort.
2, asphalt material mixed with modified rubber powder can improve the viscosity of asphalt, enhance the resistance to deformation, and has better sealing performance. Water damage of expressway is still an important factor in the early destruction of expressway, and water damage greatly shortens the service life of expressway. According to research, modified rubber powder modified asphalt on the road will form about 3mm thickness of asphalt mo, can completely prevent rain infiltration downward, to protect the roadbed. Second, in the above layer paving asphalt mixture, the modified rubber powder modified asphalt stress absorbed layer at the top of the modified rubber powder modified asphalt will be secondary melting, via the pavement compaction to full fill the surface cracks at the bottom of the mixture, which ruled out the possibility of interlayer water, prevent water damage of bad effect, make the pavement waterproof layer to enhance the performance, It can increase the service life of road surface 1-3 times.
5. Instructions for use
1. According to the proportion in the design formula, it is advisable to add modified rubber powder into the asphalt mixing tank to disperse evenly and swell and develop. Adjust the production temperature according to the proportion of modified rubber powder, the working temperature is between 180°C and 195°C.
2, modified rubber powder as asphalt modifier incorporation proportion, 15%, 20%, 25%, 30%, 40%, 50%, according to the specific product application requirements.
3. The production time of modified asphalt modified by modified rubber powder is about 1.5 hours shorter than that of modified asphalt modified by vulcanized rubber powder, and the incorporation amount is increased by about 10%.
