Description

A kind of SBS modified asphalt stabilizer

Technical field

The present invention relates to a kind of SBS modified asphalt stabilizer.

Background technology

There is many changes in highroad and road: traffic flow and travel frequency sharp increase, and the axle of freight is heavy constantly to be increased, and generally carries out divided lane one-way traffic, requires to improve road surface resistance to flow further, i.e. the ability of Rut resistance under high temperature; Improve flexible and elasticity, i.e. the ability of cracking resistance under low temperature; Improve abrasion performance ability and increase the service life.SBS modifying asphalt has the elastic recovery capability of excellent high temperature Rut resistance, low temperature cracking resistance, anti-fatigue performance and excellence, can meet application demand.But the character of SBS itself determines the poor compatibility of itself and pitch, just partly mix with pitch, easily SBS and pitch phenomenon of phase separation is there is, so solve modifying asphalt main thermodynamic stability problem existed in production and use to become one of focus of research modifying asphalt in thermmal storage process.In order to improve the dispersion of SBS in pitch, improving the stability in storage of modifying asphalt, normally in modifying asphalt, adding stablizer.

Summary of the invention

For the deficiencies in the prior art, the problem to be solved in the present invention is, provides a kind of SBS modified asphalt stabilizer, improves the high and low temperature stability of asphalt, for high request highway pavement provides good guarantee, improves the thermotolerance of SBS modifying asphalt.

For solving prior art problem, technical scheme provided by the invention is, a kind of SBS modified asphalt stabilizer, and it is made up of the raw material of following parts by weight:

Promotor 8-24 part, dithio morpholine 4-9 part, maleic anhydride 6-11 part, dicumyl peroxide 8-13 part, defoamer 3-5 part, nanometer polyoxyethylene 8-14 part, nanometer P contained compound 11-17 part, Zinic stearas 4-9 part, dibasic lead phosphite 6-9 part, internal lubricant 2-4 part, antioxidant 9-16 part, vulcanization crosslinking agent 8-16 part, positively charged ion rubber powder 20-45 part, calcium chloride 8-16 part, wilkinite 20-35 part.

The invention has the beneficial effects as follows: SBS modified asphalt stabilizer of the present invention, improve the high and low temperature stability of asphalt, for high request highway pavement provides good guarantee, improve the thermotolerance of SBS modifying asphalt.
