Problems solved by technology

[0007] The technical problem mainly solved by the present invention: the current traditional snow-melting agent is relatively slow in melting snow, and it is easy to refreeze after snow melting. Although the commonly used "chloride salt" snow-melting agent has good snow-melting and anti-freezing effect, it cannot be degraded by itself, and the residue It will cause the death of crops. In addition, the damage to the road surface is also very large, which seriously threatens the safety of industrial facilities, and the price of calcium magnesium acetate deicing agent is relatively high. The method uses bamboo green strips as raw materials, artificially pumps hemp, modifies with alkaline solution and ferments to obtain bamboo fibers, then carbonizes bamboo charcoal fibers into bamboo charcoal fibers, and crosslinks with starch crosslinking agent and acetate to obtain semi-finished products , and then fully mix the semi-finished product with zinc dihydrogen phosphate, thiourea and anti-skid agent and pack it into a bag to obtain a bamboo charcoal fiber snow-melting agent

example 1

[0024] First, take 1kg of bamboo green strips and cut them into 5cm pieces with a cutting machine, put them into an oven at 70°C and bake them for 1 hour, then manually tear them to extract the bamboo flax, and put the bamboo flax at a concentration of 0.2mol / L After soaking in the hydrochloric acid solution for 1 hour, take it out, air-dry it naturally, then soak it in a sodium hydroxide solution with a concentration of 0.3mol / L for 1 hour, and air-dry it naturally; After rinsing for 30 minutes, take it out, spray the emulsified oil evenly on the surface, put it into the fermenter and seal it for 10 days at 28°C for fermentation. After the fermentation is completed, take it out and rinse it with deionized water until the pH reaches 6, then move it into the oven and dry it at 50°C Dry, use a carding machine to comb and cut it short to make bamboo fibers; then put the above-mentioned bamboo fibers into a carbonization furnace, raise the temperature to 160°C, and carry out prelim...

example 2

[0027] First, take 1.5kg of bamboo green strips and cut them into 7cm pieces with a cutting machine, put them into an oven at 90°C and bake them for 2 hours, then extract the bamboo hemp by hand tearing, and put the obtained bamboo hemp into the concentration of 0.3mol / After soaking in 1 L of hydrochloric acid solution for 2 hours, take it out, air-dry it naturally, then immerse it in a sodium hydroxide solution with a concentration of 0.4mol / L for 2 hours, and then air-dry it naturally; After rinsing the solution for 50 minutes, take it out, spray emulsified oil evenly on its surface, put it into a fermenter and seal it for fermentation at 35°C for 13 days, after the fermentation is completed, take it out and rinse it with deionized water until its pH reaches 7, then move it into an oven at 55°C Drying, combing and cutting it with a carding machine to make bamboo fibers; then put the above-mentioned bamboo fibers into a carbonization furnace, heat up to 170°C, and perform pre...

example 3

[0030] First, take 2kg of bamboo green strips and cut them into 10cm pieces with a cutting machine, put them into an oven at 100°C and bake them for 3 hours, then extract the bamboo hemp by hand tearing, and put the obtained bamboo hemp in a concentration of 0.4mol / L After soaking in the hydrochloric acid solution for 3 hours, take it out, air-dry it naturally, then immerse it in a sodium hydroxide solution with a concentration of 0.5mol / L for 3 hours, and then air-dry it naturally; After rinsing for 60 minutes, take it out, spray emulsified oil evenly on the surface, put it into a fermenter and seal it for fermentation at 38°C for 15 days. After the fermentation is completed, take it out and rinse it with deionized water until its pH reaches 8, then move it into an oven and dry it at 60°C Dry, use a carding machine to comb and cut it short to make bamboo fibers; then put the above-mentioned bamboo fibers into a carbonization furnace, heat up to 180°C, and carry out preliminary...

Abstract

The invention discloses a preparation method for a bamboo carbon fiber snow-melting agent, and belongs to the technical field of materials. The preparation method comprises the following steps: using bamboo skin as a raw material, conducting manual linen suction, alkaline solution modification and fermentation to obtain bamboo fiber, carbonizing the bamboo fiber into bamboo carbon fiber, crosslinking the bamboo carbon fiber and acetate through a starch crosslinking agent to obtain a semi-finished product, fully mixing the semi-finished product, zinc dihydrogen phosphate, thiourea and an anti-skidding agent, and bagging the mixture so as to obtain the bamboo carbon fiber snow-melting agent. Examples prove that the operation is simple and feasible, the prepared snow-melting agent is low in cost, the snow-melting effect is obvious, the snow-melting speed is accelerated by 75% or above, the snow-melting agent can degrade by self, and no harm is caused for the water body and environment after the snow is molten.

Description

technical field [0001] The invention discloses a preparation method of a bamboo charcoal fiber snow-melting agent, belonging to the field of snow-melting agent preparation. Background technique [0002] The snow and ice on the road surface in winter greatly reduces the adhesion coefficient of the road surface, seriously affecting the smoothness of the road and driving safety. Traditional snow removal methods such as manual, mechanical, and snow-melting agents cannot maintain road safety anytime, anywhere for a long time. In practical application, various snow-melting products continue to appear. Snow-melting agent, also known as deicing salt and road antifreeze, is a snow-removing substance widely used in winter. Mainly, and add an appropriate amount of corrosion inhibitors, anti-slip agents and other additives. [0003] "Chloride salt" deicing agent is better for snow melting and antifreeze, and the price is also cheap, but after the ice or snow melts into liquid, its salt...
