Abstract

The invention relates to the technical field of anti-freezing deicing agents, in particular to an efficient corrosion-inhibiting anti-freezing deicing agent. The efficient corrosion-inhibiting anti-freezing deicing agent comprises, by weight, 80-99.5% of sodium chloride, 0.1-15% of corrosion inhibitor and 0.4-5% of assistant. The sodium chloride is refined vacuum salt; the corrosion inhibitor is composed of molasses, sodium gluconate, zinc dihydrogen phosphate, sodium metasilicate nonahydrate and sodium lignin sulfonate; the assistant is composed of sodium carboxymethylcellulose, polyvinylpyrrolidone and urea. By the anti-freezing deicing agent, corrosion to metal and cement concrete can be effectively lowered; the selected molasses in the corrosion inhibitor is a byproduct of the sugar industry, and has strong chelating capability on bivalent cations; the sodium carboxymethylcellulose and the polyvinylpyrrolidone used in the assistant can enhance the strength of granulation salt granules, and collapse of the granule structure during transportation and use are avoided; the production process is simple and easy to implement and performed at normal temperature and under normal pressure, conditions are mild, and granular solid is suitable for large-scale mechanical dispersion.

Description

technical field [0001] The invention relates to the technical field of antifreeze and deicing agents, in particular to a high-efficiency corrosion-inhibiting, antifreezing and deicing agent and a preparation method thereof. Background technique [0002] In cold winter, ice and snow greatly reduce the adhesion coefficient of vehicle tires. According to relevant data, the adhesion coefficient of dry asphalt pavement is about 0.6, while that of snow-covered road is 0.2, and that of icy road is 0.15, respectively. 1 / 3 and 1 / 4 of the asphalt road. Therefore, the snow and ice on the road surface due to snowfall will have a serious adverse effect on the smoothness of the road and driving safety, causing the car to skid, significantly prolonging the braking distance, and even brake failure and direction loss, resulting in serious traffic accidents. In order to ensure smooth roads and driving safety, avoid traffic accidents or reduce traffic accidents, improve road capacity and oper...
