Abstract
The invention discloses an improved stabilizer for SBS modified asphalt. The improved stabilizer is prepared from the following raw materials in parts by weight: 8-14 parts of sulfur, 5-9 parts of tetraethylthiuram disulfide, 6-13 parts of benzoyl peroxide, 12-16 parts of an active agent, 9-14 parts of nano polyethylene glycol, 10-20 parts of ethylene-vinyl acetate copolymer, 7-10 parts of stearic acid, 5-11 parts of lead stearate, 1-2 parts of antioxidant, 7-15 parts of an antifoaming agent, 20-40 parts of deionized water, 8-12 parts of zinc oxide, 0.5-1 part of phenol-free antioxidant, and 0.2-0.4 part of catalyst. The improved stabilizer has the beneficial effects that, according to the improved stabilizer for the SBS modified asphalt disclosed by the invention, the high temperature track resistance and low temperature crack resistance are promoted, the stability performance of the asphalt is improved, the production efficiency is improved, and the energy consumption is reduced, so that the SBS modified asphalt has higher storage stability and is environmentally -friendly.
Description
Technical field
The present invention relates to the SBS modified asphalt stabilizer of a kind of improvement.
Background technology
Along with the development of society, the grade of highway is more and more higher, but the loading capacity of automobile is the most increasing simultaneously, the most on a highway, has substantial amounts of train vibration influence every day, and the performance requirement for highway is higher, the ability of Rut resistance to be had；Improve flexible and elastic, i.e. the ability of cracking resistance under low temperature；Improve abrasion performance ability and increase the service life.SBS modified pitch has excellent high temperature Rut resistance, low temperature cracking resistance, anti-fatigue performance and the elastic recovery capability of excellence, can meet application demand.But the character of SBS itself determines the poor compatibility of itself and Colophonium, mix with Colophonium simply part, SBS and Colophonium phenomenon of phase separation is easily there is, so the thermodynamic stability problem that solution modified pitch is primarily present in producing and using becomes one of focus of research modified pitch during thermmal storage.In order to improve SBS dispersion in Colophonium, improve the storage stability of modified pitch, it is common that in modified pitch, add stabilizer.
Summary of the invention
For the deficiencies in the prior art, the problem to be solved in the present invention is, the SBS modified asphalt stabilizer of a kind of improvement is provided, improve high temperature Rut resistance, anti-low-temperature cracking, improve the stability of Colophonium, improve production efficiency, reduce energy consumption, SBS modified pitch is made to have a more preferable storage stability, and environmental protection.
For solving prior art problem, the technical scheme that the present invention provides is, the SBS modified asphalt stabilizer of a kind of improvement, and it is made up of the raw material of following parts by weight:
Sulfur 8-14 part, tetraethylthiuram disulfide 5-9 part, benzoyl peroxide 6-13 part, activating agent 12-16 part, nanometer Polyethylene Glycol 9-14 part, ethylene-vinyl acetate copolymer 10-20 part, stearic acid 7-10 part, lead stearate 5-11 part, antioxidant 1-2 part, defoamer 7-15 part, deionized water 20-40 part, zinc oxide 8-12 part, without phenol antioxidant 0.5-1 part, catalyst 0.2-0.4 part.
The invention has the beneficial effects as follows: the SBS modified asphalt stabilizer of the improvement of the present invention, improve high temperature Rut resistance, anti-low-temperature cracking, improve the stability of Colophonium, improve production efficiency, reduce energy consumption, make SBS modified pitch have a more preferable storage stability, and environmental protection.
