Abstract
The present invention provides a stabilizer for asphalt emulsion by which asphalt emulsion having a good chemical stability and being excellent in stationary stability and storage stability can be obtained. A polyoxyethylene adduct compound having a terminal group A selected from a C8-22 alkyl group etc., a terminal group B selected from C1-4 alkyl group etc., and 130 to 500 oxyethylene groups on the average for bonding the terminal groups A and B is used as a stabilizer for asphalt emulsion.
Claims13
A stabilizer for asphalt emulsion, comprising a polyoxyethylene adduct compound (1) having:
- a terminal group R1 selected from a C8-22 straight-chain or branched alkyl group and a C8-22 straight-chain or branched alkenyl group,
- a terminal group R2 selected from a hydrogen atom, a C1-4 straight-chain or branched alkyl group and a C1-22 straight-chain or branched acyl group, and
- 130 to 500 oxyethylene groups on the average for bonding the terminal groups R1 and R2.
A stabilizer for asphalt emulsion, comprising a polyoxyalkylene polymer (2) with a weight average molecular weight of 12000 to 30000 containing oxyethylene groups and oxypropylene groups wherein the total molecular weight of the oxyethylene groups accounts for 75% or more of the total molecular weight of the oxyethylene groups and oxypropylene groups.
