Hong Mian HM-WD13000 stabilizer product specification

A series of HMWD modified asphalt stabilizer product introduction

Our company is committed to research and development of modified asphalt production technology, combined with the characteristics of SBS modified asphalt, the industrial technology of polymer materials into SBS modified asphalt technology, the synthesis and compounding technology developed efficient modified asphalt stabilizer, the reaction mechanism is: in the life of the stabilizer free radical production mechanical shear and thermal oxidation under a certain trigger SBS polymer chains, active functional group crosslinked grafted asphalt, SBS- asphalt to form graft copolymers, as SBS asphalt with excellent compatibility, so that the polymer and asphalt forming stable colloid system, and ultimately improve the hot storage stability of modified asphalt, solve the storage problem of segregation of asphalt, modified asphalt product storage stability can be reached more than 60 days.

On the basis of further research on the compatibility and reaction mechanism of SBS and matrix asphalt, the HMWD series SBS modified asphalt stabilizer was developed to adapt to different matrix asphalt, SBS and modified technology. This series can not only effectively solve the usually existing polymer modified asphalt storage stability and stability of segregation (attenuation), while both the following characteristics: 1, auxiliary chemical modification, further improve product performance index of modified asphalt; 2, to ensure that the modified asphalt during hot storage stability and durability index; 3, targeted, SBS, matrix asphalt is suitable for different brands, HMWD is a series of 1-4 models, which are suitable for different basic asphalt, SBS modified; 4, good economic performance, reduce the cost of the total change, no toxicity and no irritation.

Two, modified asphalt stabilizer quality index

Appearance: gray white particles

The content of effective ingredients: 95%

Apparent density: 0.5-1.0g/cm3

Melting point: more than 110 DEG C

Fineness (80 mesh sieve): less than 2%

The moisture is less than 0.5%

Three, the use of the amount and methods

Adding amount: 0.2% or so, add the temperature: 175 degrees C - 195

Adding way: with the polymer at the same time to join the matrix asphalt, adding after the colloid mill grinding, and then in the development of the tank can be developed; can also be evenly added to the asphalt mixture.

According to the different reaction of different polymer / matrix asphalt system, the optimum scheme was determined by experiment.

1, this product has no toxic effect, but the solid dust on the person's eye, respiratory tract has certain stimulation, it is recommended to wear certain protective equipment.

2, because of the differences between the asphalt component, do test compatibility test before use, to prevent the excessive production of gel phenomenon of stabilizer.

3, this product is no rain moisture, heat, please store in a cool dry place; and other chemicals mixed before use, please consult the manufacturer.

Four, packaging and storage

Packing: 25 kg / bag

Storage: keep at room temperature, drying, isolation and alkali, heat, prevent moisture;

Shelf life: one year.

Five, service

1, to ensure the stability of asphalt products to customers will not have any damage or storage mixing equipment.

2, for different modified asphalt equipment selection of the best production and processing technology.

3, according to different matrix asphalt and different SBS gives the best solution.
