沥青抗剥落剂的表面主要有黑褐色粘稠液体与棕黄色粉末固态,是由氨基胺衍生出来的一种抗剥落剂,能够同时适用于酸、碱两种石料的两性活性有机高分子化合物;添加在沥青混凝土的使用中,不但可以增加沥青混凝土的粘度,而且还大大的减少了水分对沥青的损害;该产品在加热时,与同类产品相比产生更少的烟雾,更保护环境。
A dark brown viscous liquid and solid surface mainly brown yellow powder anti stripping agent of bitumen is derived from amino amine is a kind of anti stripping agent, amphoteric active polymeric compounds can also apply to the two kinds of acid and alkali aggregate; add in the use of asphalt concrete, not only can increase the viscosity of asphalt concrete. But also greatly reduce the water damage of asphalt; the product at the time of heating, compared with similar products produce less smoke, more to protect the environment.
沥青抗剥落剂与集料的化合反应是利用集料表面进行物理吸附或者是利用其的特殊化学结构来进行的,在他们之间形成一种坚强的化学纽带;这样看来不但提高了沥青与集料的粘和性,而且还提高了抗热老化性及抗水损害性,从而使路面的寿命得到了延长;特别是对于提高酸性的二氧化硅含量高的玄武岩、安山岩、花岗岩等石料与沥青的粘附性方面具有很大的帮助。
Asphalt anti stripping agent and aggregate reaction is the use of aggregate surface physical adsorption or to use its special chemical structure of the formation of a strong chemical bond between them; it can not only improve the asphalt and aggregate and adhesive, but also improves the thermal aging resistance and resistance to water damage, so that the pavement life is prolonged; especially of great help for improving the adhesion of basalt, andesite, granite stone and asphalt content of high silica acid. |
