Coated long-lasting anticoagulant and preparation method thereof

Abstract

The invention discloses a coated long-acting anti-icing agent and a preparation method thereof. The raw material of the invention adopts large-grained salt, and the price is relatively low, which saves costs; the coated long-acting anti-icing agent obtained by the method of the present invention can During the preparation process, after being coated and coated with a modified salt storage carrier on the surface, the salt compound is slowly released, and the long-term performance of the anti-condensation point asphalt road surface admixture is improved. The snow-melting effect on the road surface can last for many years, greatly reducing the cost of road surface management and maintenance in winter; the method of the invention is simple in process, and the main equipment and raw materials used can be purchased in the market, and large-scale production can be realized.

Description

technical field [0001] The invention relates to the field of municipal construction supplies, in particular to a coated long-acting anti-icing agent and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of my country's economy, high-grade highways and urban roads have also developed rapidly. The gradual improvement of the road traffic network has greatly promoted and guaranteed the development of my country's social economy, but we should also see the constraints in the process of road construction, the most important of which is the phenomenon of snow on roads in winter. As far as the current situation is concerned, the winter ice and snow removal methods commonly used at home and abroad include: artificial snow removal method, snow melting agent method and mechanical ice and snow removal method, etc., and sometimes the three are properly combined according to specific conditions. The widely used deicing agent is chlori...

Problems solved by technology

Kang Jie of Chongqing Jiaotong University conducted a research on self-made salt-storage aggregates, and proved that the aggregates after salinization of zeolite can replace the aggregates in asphalt mixtures to have the effect of deicing and snowing the road surface. Applied to the micro-surface treatment of pavement, an anti-icing micro-surface is proposed, and its deicing performance is verified, which proves that the salt storage aggregate has a certain anti-icing effect, but the long-term effect needs to be studied and strengthened

In terms of the long-term effect of ice and snow melting, Japan has carried out long-term measurement based on actual projects, and proved that after 5-6 years, the salt-storage road surface still has a certain de-icing and snow-removing function. There are some studies on this aspect, but the research is limited to the immersion method under static water conditions, which cannot reasonably simulate the actual situation of the road surface

[0006] Polymer material coating technology has been used in agriculture and medicine and other fields, such as drug coating and chemical fertilizer and pesticide coating. It has not been reported that it is applied to anti-icing agent to coat salinity
