The compression strength of road cold-repairing material is substantially reduced with flexural tensile strength, therefore concludes that the adhesive-hardening speed of road cold-repairing material
It substantially reduces.The reason is that diesel oil is not soluble in water, watering cannot separate diesel oil from cold-repairing material.The presence of formamide can be with
So that when sprinkling water in cold-repairing material system, the formamide separation and in conjunction with water from cold-repairing material system rapidly.Point of formamide
From making between pitch viscosity enhancing so that the gap between each asphaltene molecule reduces, bonding more closely, thus
So that cold-repairing material system quick-hardening.
3, as shown in Table 4, comparative example 1-5 and comparative example 3 do not add nanoscale titanium dioxide under illumination condition
The odorousness that the cold-repairing material system of titanium active material comes out is larger, has larger harm to environment.And photo-catalytic nano
Grade titanium dioxide active material can effectively decompose the harmful substance in cold-repairing material system under light illumination, so that cold-repairing material
The odorousness that system comes out is lower, and unobvious.
4, polyurethane modified epoxy third is added at low ambient temperatures in as shown in Table 5, comparative example 1-5 and comparative example 4
After olefin(e) acid ester, due to the cold resistance of acrylate, the cold-resistant anti-freezing property of road cold-repairing material system is greatly strengthened.Reason is
Polyurethane modified epoxy acrylate molecule is dispersed in system, and asphaltene molecule is surrounded so that asphaltene molecule by
The protection of polyurethane modified epoxy acrylate molecule is to enhance cold tolerance.
