As shown in table 3, there is excellent hydrophobicity, anticoagulant ice by meeting the coating that the embodiment of the present invention 1-5 is formed
Property and slow release.In addition, by meeting coating that the embodiment of the present invention 1-5 is formed in the test process for evaluating slow release
In, there is not apparent salt to be precipitated, and coating is also not affected by destruction, i.e., these coatings can be used for a long time.
As shown in table 3, although there is good hydrophobicity by meeting the coating that comparative example 1-3 of the invention is formed,
It is compared with effect of the invention, anticoagulant ice and slow release are poor.
The dosage of anticoagulant ice modifying agent in comparative example 4 is very few, therefore anticoagulant ice and slow release are poor.Although by comparative example
The coating that 5 coating is formed has good hydrophobicity, anticoagulant ice and slow release, still, due to the anticoagulant ice in comparative example 5
The dosage of modifying agent is excessive, carries out repeating to observe that surface of test piece has gradually appeared white when testing in the evaluation of slow release
Salt is precipitated, this will lead to the pollution in actual use to environment;In addition, being excessively used for anticoagulant ice agent will lead to cost mistake
It is high.
When emulsified asphalt excessive (comparative example 6), the binding force on coating and road surface is insufficient and hydrophobicity declines;And when emulsification
When pitch very few (comparative example 7), the resistance to external impacts of coating are insufficient.Therefore, slow release deterioration in both cases, makes
It is also deteriorated with the service life.
