Abstract

The invention discloses a non-amine asphalt anti-stripping agent, which is prepared from the following components in parts by weight: 50 to 60 parts of paraffin, 20 to 30 parts of oleic acid, 20 to 30 parts of sodium dodecyl phosphate, 50 to 60 parts of molecular sieves, 4 to 6 parts of long-chain organic silane, 3 to 7 parts of amino silane, 4 to 10 parts of antioxidants, 2 to 4 parts of phosphorus pentoxide and 1 to 3 parts of manganese dioxide. The non-amine asphalt anti-stripping agent provided by the invention can effectively improve the adhesion of a pavement asphalt material to various stones, improve the aging resistance of the pavement asphalt material and prolong the service life of the pavement asphalt material.

Description

technical field [0001] The invention relates to the field of asphalt anti-stripping agents, in particular to a non-amine asphalt anti-stripping agent and a preparation method thereof. Background technique [0002] Pavement asphalt materials are prone to loosening and potholes after long-term use. Therefore, in order to reduce the damage of asphalt pavement, it is necessary to add asphalt anti-stripping agent to asphalt or asphalt mixture. Most of the traditional asphalt anti-stripping agents are amines, which are more polluting to the environment, have poor effect on improving the adhesion of asphalt, and have poor anti-ultraviolet aging performance. Contents of the invention [0003] In view of the above problems, the present invention provides a non-amine asphalt anti-stripping agent and a preparation method thereof, which have the advantages of less environmental pollution, excellent anti-ultraviolet aging performance, and can effectively improve the adhesion between as...
