Composite anti-freeze agent

Abstract

The invention discloses a composite anti-freeze agent. The composite material comprises the following raw material components: in parts by weight, 20-30 parts of magnesium chloride, 8-15 parts of ethylene glycol, 2-6 parts of silane coupling agent, 2-6 parts of terpene resin, 3-8 parts of zeolite, 6-13 parts of diatomaceous earth, 1-3 parts of polypropylene fiber, 1-3 parts of dimethicone, 2-6 parts of maleic anhydride and 1-3 parts of a corrosion inhibitor. Different degrees of coating are carried out on the salt substance by other materials through chemical bonding, not only can improvementof the sustained release effect, avoidance of corrosion of the salt substance to bridge steel bars, no pollution and damage to the environment and good compatibility among the materials be achieved, but also certain heat resistance can be achieved so as to meet the production process requirements of blending with asphalt; and in addition, the anti-freeze composite material has microscopic compatibility with asphalt so that the mechanical properties of an asphalt pavement can be enhanced.

Description

technical field [0001] The invention relates to a pavement material, in particular to a composite anti-icing agent. Background technique [0002] In the early winter or the end of winter, the temperature alternates between cold and warm, and the snowfall on the road surface gradually melts under the action of driving load. Under the action of negative temperature, it is easy to form thin ice, and the anti-skid performance of the road surface drops sharply. Ice and snow cause the adhesion coefficient of vehicle tires to be greatly reduced. Therefore, on ice and snow roads, cars are prone to skidding and deviation, and the braking distance is significantly prolonged, which seriously affects the operational stability and safety of the vehicle, and the incidence of traffic accidents is high. The existing anti-icing additives cause great damage to the environment due to the excessive use of inorganic salts, especially the corrosion of bridge steel bars. Moreover, the existing an...

Problems solved by technology

Therefore, on ice and snow roads, cars are prone to skidding and deviation, and the braking distance is significantly prolonged, which seriously affects the operational stability and safety of the vehicle, and the incidence of traffic accidents is high.

The existing anti-icing additives cause great damage to the environment due to the excessive use of inorganic salts, especially the corrosion of bridge steel bars. Moreover, the existing anti-icing additives have poor heat resistance and cannot meet the requirements of hot-mix asphalt co-production. The production process of the mixture affects the wear resistance and strength of the asphalt pavement due to its poor mechanical properties
