Abstract
A cementnig material for the expansion joint of bridge contains petroleum asphalt, styrene-butadiene block polymer (SBS), ethylene-vinyl acetate copolymer (EVA), petroleum resin and calcium carbonate as filler in mass ratio of 100:(10-22):(3-6):(0-10):(40-75). It may also contains polyethylene (PE) and natural asphalt.
Description
Field that the present invention belongs to
The invention belongs to material of construction, especially for the agglutinate of the gapless bridge expansion joint installation in the bridge construction.
The prior art background
The problem that the cementing material for bridge expansion joint of prior art exists at first is the bad adaptability to envrionment temperature, and softening temperature is low, produces distortion under hot conditions, and resistance to low temperature is poor simultaneously, and is easy to crack under the low temperature condition; Next is that adhesivity is low and rebound resilience is poor.
The innovation and creation content
The objective of the invention is to propose a kind of new solution of cementing material for bridge expansion joint.Solve problems of the prior art.
The composition of cementing material for bridge expansion joint of the present invention comprises petroleum pitch, vinylbenzene-butadiene block polymkeric substance (SBS), ethene-acetate ethylene copolymer (EVA), petroleum resin and pearl filler; The mass ratio of each component is:
Petroleum pitch: SBS: EVA: petroleum resin: pearl filler
＝100∶10-22∶3-6∶0-10∶40-75。
Be in the component of agglutinate of the present invention to comprise polyethylene (PE) and rock asphalt.
Agglutinate of the present invention belongs to mixture, and it is a kind of special elastic-plastic material, is specially adapted to the expansion gap device of concrete-bridge.
The cementing material for bridge expansion joint that is mixed according to the present invention program is suitable for the use temperature scope of concrete-bridge fully, and its hot mastication point temperature is higher than 110 ℃, and the rut factor has good high temperature deformation resistance performance greater than 50KPa in the time of 76 ℃; Its 5 ℃ of ductilities are greater than 10cm; Stiffness S＜the 150Mpa of low-temperature bending beam rheology (BBR) the test gained under-24 ℃ of conditions, m value＞0.3; Extensibility in the time of 0 ℃＞40% has good anti-cold cracking performance.
The cementing material for bridge expansion joint that is mixed according to the present invention program and the adhesivity of lime carbonate are 5 grades, have good adhesivity; Rebound degree in the time of 25 ℃ has the better elastic recovery performance greater than 90%.
The working of an invention mode
The ratio of each component of a kind of embodiment of agglutinate of the present invention is:
Petroleum pitch: SBS: EVA: petroleum resin: pearl filler
＝100∶18∶4∶10∶60。
The ratio of each component of the another kind of embodiment of agglutinate of the present invention is:
Petroleum pitch: SBS: EVA: petroleum resin: pearl filler: PE: rock asphalt
＝100∶18∶4∶10∶60∶4∶4。
The technical target of the product of this embodiment can reach: softening temperature: 127 ℃; The rut factor (76 ℃): 77.9KPa; Ductility (5 ℃): 15.8cm; Extensibility (0 ℃): 87.3%; Rebound degree (25 ℃) 98%; BBR test: stiffness S (24 ℃): 92.3Mpa; M (24 ℃): 0.327; Adhesivity: 5 grades
