Embodiment 1

[0041] Embodiment 1: preparation, refining and concentration of wood vinegar

[0042] Preparation of wood vinegar: Add 500 grams of fungus chaff into the retort, conduct retort at a temperature not exceeding 300°C, and cool the discharged gas through a condenser at 90-200°C to collect 145-160 grams Brown-black crude wood acetic acid solution, 140-150 grams of charcoal.

[0043] The crude wood vinegar is still for 1 to 6 months, and the organic phase in the middle is collected after layering, which mainly contains 7.32% acetic acid, 0.85% formic acid, 0.62% propionic acid, 0.15% formaldehyde, 0.25% of furfural, 0.62% of phenol. Phenol is the main reason for the coloration of wood vinegar, so it needs to be decolorized. Put the crude wood vinegar in a container, take copper / lithium composite metal ion as a catalyst, feed air at a temperature of 60 to 80°C and a pressure of 2.7MPa for 5 hours, wherein the catalyst: phenol molar ratio is 1: 2mol, Cu 2+ : Li 2+ =1:3. Phenol i...

Embodiment 2

[0046] Embodiment 2: Preparation of CMA melting ice and snow material

[0047] Preparation of CMA (calcium acetate, magnesium salt) melting ice and snow materials:

[0048] Add 200kg of oxygen calcium, 112kg of oxygen magnesium, and 50kg of water in the reaction kettle, mix well and make a paste, then gradually add 150kg of 20wt% wood vinegar, and control the reaction temperature by controlling the feeding speed of the wood vinegar The temperature does not exceed 70°C; after the reaction is completed, the insoluble matter is removed by filtration, evaporated and concentrated to a solid content of 30 wt%, and dried to obtain a solid CMA snow-melting material.

[0049] The influence of temperature on the reaction; the above reaction temperature is controlled at 50-70°C, and the reaction is easy to control. Under this temperature condition, after 60-100min, the product yield is higher and the performance is better.

[0050] The influence of reactant concentration on product yiel...

Embodiment 3

[0052] Example 3: The relationship between the amount of CMA ice and snow melting material and the amount of ice melting

[0053] Put 50ml of water into each of eight 100ml porcelain crucibles, and place them in a thermostat at -10°C for 12 hours to make ice cubes with the same shape. Take CMA deicing agents with different molar ratios, prepare each sample into a saturated solution, then weigh 60ml of deicing agents for each sample, pour them into the ice cubes prepared above, and measure the total amount of liquid after 30 minutes. The results are shown in the table below:

[0054] Table 1. The relationship between snow melting dose and ice melting amount of different molar ratios of CMA

[0055] CaO / MgO

[0056] From the above table 1, image 3 It can be seen that the amount of ice melting varies with the unpredictable CaO / MgO mole, and when the CaO / MgO mole is equal, the amount of ice melting reaches the highest value,

Abstract

The invention provides a capsule type snow ice melt inhibiting material doped into asphalt pavement filling materials in road building or pavement building, a preparation method and application thereof. The capsule type snow ice melt inhibiting material consists of a capsule wall, a capsule core and protection solution, wherein the capsule core is formed by mixing an absorbent with a grain diameter of 30 micrometers and a nanometer bone material, wherein the absorbent is modified by absorbing calcium acetate and magnesium acetate; the mass ratio of capsule wall chitosan or ethyl cellulose to polyethylene glycol is 1:1, the ratio of the mass sum of the modified adsorbent and the bone material to the capsule wall mass is 10:1; the mass ratio of the modified adsorbent to the bone material is 7:3; the mass ratio of the modified adsorbent to the calcium acetate to the magnesium acetate thereof is 2:1:1-2:1.2:0.8; the calcium acetate and the magnesium acetate solution are added into the adsorbent respectively; and the solution is oscillated on an oscillator at room temperature, and is stirred and oscillated continuously, and is filtered after standing; the capsule core is dispersed into the capsule wall solution, and is slowly dripped into the polyethylene glycol solution in stirring to prepare the snow ice melt inhibiting material to be doped into the asphalt pavement filling material after stirring, vacuum filtering, cleaning and drying.

Description

technical field [0001] The present invention relates to a slow-release ice and snow melting material and its preparation method and application, in particular to a kind of anti-melting ice and snow material and its preparation method and application, in particular to a shell-coated road or road surface mixed with asphalt pavement filler Material for inhibiting melting ice and snow, preparation method and application. technical background [0002] In the past two decades, due to global warming and serious environmental pollution, the temperature difference between cold and hot climates in winter has changed abnormally, and the freezing and thawing have frequently alternated, causing the road surface and ice and snow layers to freeze, causing many vehicles to rear-end. Freezing snow and freezing have blocked important land traffic arteries such as urban areas, expressways, and airports. Traffic outages have seriously threatened the daily lives of the people and affected the de...
