Embodiment 1

[0046] 1. Preparation of plant-based humic acid solution

[0047] 1.1 Dissolution of plant-based humic acid

[0048] Weigh 30g of plant-based humic acid at room temperature, dissolve it in 500ml of distilled water, and stir conventionally to disperse the plant-based humic acid in the distilled water to form a mixture of plant-based humic acid and water.

[0049]1.2 Primary degradation treatment

[0050] Add glacial acetic acid to the mixture of plant-based humic acid and water to make the pH value reach 4.5, use conventional methods to raise the temperature to 40°C, start stirring, and add 3g of cellulase under stirring state, constant temperature reaction After 3h, the primary degraded humic acid solution was obtained.

[0051] The cellulase used in the present invention is a compound enzyme mainly composed of exo-β-glucanase, endo-β-glucanase and β-glucosidase, as well as highly active xylan Enzymes that act on cellulose and products derived from cellulose. Although humi...

Embodiment 2

[0063] In addition to weighing 40g of plant-based humic acid to dissolve in step 1.1, adjust the pH value to 5.0; in step 1.2, heat up to 30°C, add 8g of cellulase, and react for 5h; in step 1.3, adjust the pH value to 3.0, and heat up to 70°C , add 40ml H 2 o 2 and 25ml of ferrous sulfate solution; react at a constant temperature of 70°C for 1.0h; add 30g of calcium chloride in step 2, and continue to react for 1.0h at 70°C; add 20g of potassium chloride, 5g of sodium citrate, 5g of Except sodium gluconate, others are all identical with embodiment 1.

Embodiment 3

[0065] In addition to weighing 35g plant-based humic acid to dissolve in step 1.1, adjust the pH value to 4.5; add 6g cellulase in step 1.2, and react for 4h; adjust the pH value to 4.0 in step 1.3, add 50ml H 2 o 2 and 25ml of ferrous sulfate solution; react at a constant temperature of 60°C for 1.0h; add 15g of calcium acetate and 30g of calcium chloride in step 2, and continue to react for 1.5h at 60°C; add 10g of potassium chloride and 5g of lemon in step 3 sodium gluconate, 5g sodium gluconate, other are all identical with embodiment 1.

[0066] It should be noted that the above-mentioned embodiments are only exemplary, and there are many ways to achieve the technical purpose of the present invention in the above-mentioned composition ratio and operating conditions. The inventor has proved through a large number of experiments that the plant-based humic acid, calcium salt, potassium salt and corrosion inhibitor used in the present invention are in the range of 30-40 part...

Abstract

The invention relates to a novel ecological environment-friendly snow-melting material, a preparation method and an ecological environment-friendly snow-melting agent, and relates to the field of snow-melting materials, and the ecological environment-friendly snow-melting material provided by the invention comprises plant-based humic acid, calcium salt, potassium salt and a corrosion inhibitor which are respectively treated by using a biological enzyme and a Fenton reagent under different acidic conditions; the components are prepared into the ecological environment-friendly snow-melting agentby controlling pH and temperature, so that the plant-based humic acid is sufficiently degraded and sufficiently reacts with positive ions in an inorganic fertilizer, and the snow-melting agent whichis good in snow-melting performance, small in facility corrosion, self-biodegradable, capable of promoting plant growth, environmentally friendly and beneficial to ecological protection is formed. Theecological environment-friendly snow melting material is wide in cost source, low in cost, simple in preparation method, suitable for industrial application and remarkable in social benefit.

Description

technical field [0001] The invention relates to a snow-melting material, in particular to an environment-friendly snow-melting material and a preparation method thereof. Background technique [0002] Snowfall in winter not only brings inconvenience to the city and transportation, but also easily causes traffic accidents, which seriously affects the traffic safety of highways and cities and the normal life of residents. The use of snow melting materials is an important way to solve the snow accumulation on the road at low cost and quickly. means. The places of use include properties in large public areas such as airports and squares; properties in densely populated areas such as communities, schools, and single-family buildings; traffic service agencies such as municipal roads and expressways, etc. According to the data of China's snow-melting agent industry, the annual sales of snow-melting agents in my country reach more than 36 billion yuan. In 2014 alone, the amount of ...
