Example Embodiment

[0022] Example 1:

[0023] The mass ratio of straw ash, straw residue, urea, disodium hydrogen phosphate, potassium acetate, ordinary Portland cement (PO32.5), and water is 30:55:3:3:5:7:15, mix and stir well, conventional Extrusion granulation, the size of the granule is 1 cm, and it can be bagged and sealed after natural drying for 20 days. The environment-friendly snow-melting anti-skid particles are sprayed on the compacted snow-covered road. After being rolled by the vehicle, the friction coefficient of the road surface is increased from 0.2 to 0.38.

Example Embodiment

[0024] Example 2:

[0025] The mass ratio of straw ash, straw residue, urea, ammonium phosphate, sodium acetate, ordinary Portland cement (PO32.5), and water is 33:50:4:4:4:9:10, mixed and stirred uniformly, and conventional extrusion Granulate, the size of the granule is 2 cm, after natural drying, put it in a bag and seal it for 20 days. The environment-friendly snow-melting anti-skid particles are sprayed on the compacted snow-covered road. After being rolled by a vehicle, the friction coefficient of the road surface is increased from 0.2 to 0.35.

Example Embodiment

[0026] Example 3:

[0027] The mass ratio of straw ash, straw residue, urea, potassium phosphate, potassium acetate, ordinary Portland cement (PO32.5), and water 37:45:5:3:3:8:12, mix and stir uniformly, conventional extrusion Granulate, the particle size is 3 cm, and place it for 20 days after natural drying, then bag and seal. The environment-friendly snow-melting anti-skid particles are sprayed on the compacted snow pavement, and the friction coefficient of the road surface is increased from 0.2 to 0.32 after being rolled by the vehicle.

Abstract

The invention relates to environmentally-friendly snow-melting antiskid particle, and belongs to the field of snow melting and skid resistance of ice-snow roads. Straw ash and straw residues are usedas main raw materials of the snow-melting antiskid particle, cement is used as an inorganic gelling agent, and urea, phosphate and acetate are added as snow-melting agents to prepare the novel snow-melting antiskid material so as to solve the problem of vehicle slipping caused by snowfall of roads in winter. The particle size of the snow-melting antiskid particle is 1-3 cm, and small particles formed after the snow-melting antiskid particle is rolled by a vehicle have an excellent antiskid effect. The black straw ash and straw residues can absorb heat easily, so melting of a snow ice layer isaccelerated under the action of a snow-melting agent, and the threat of the smooth ice and snow road surface to traffic safety is relieved. Besides, the straw ash, straw residues, urea and phosphate flowing into green belts at two sides of a road or surrounding farmlands along with molten snow can provide potassium, nitrogen and phosphate fertilizers for growth of plants in order to promote growthof green belt plants or crops, and the particle has a good ecological environmentally-friendly effect.

Description

technical field [0001] The invention belongs to the field of snow-melting anti-skid on ice and snow roads, and relates to an environment-friendly snow-melting anti-skid particle. Background technique: [0002] With the rapid development of highway construction in our country, the number of highways built in high-latitude, high-altitude cold regions has increased rapidly. Snow on the road caused by snow in winter freezes and the friction coefficient of the road surface decreases. It is easy to cause vehicle skidding and traffic accidents, which seriously endanger the safety of drivers and passengers. Therefore, snow removal and skid resistance in winter have become an important task in road maintenance. For the snow layer and ice layer that is easy to form on the road in winter, the effective way is to apply slag, gravel, etc. to prevent slipping, and to apply snow melting salt to remove snow and ice. However, the slag and gravel sprinkled on the road will pollute the groun...
