preparation example Construction

[0020] The preparation of cactus glue is to mix cactus and water according to the mass ratio of 1:2 and squeeze the juice, collect the squeezed juice, filter, and concentrate the filtrate to 50% of the volume of the filtrate to obtain the cactus glue.

[0021] The configuration of the zein solution is to mix the zein with an ethanol solution with a mass fraction of 85% at a mass ratio of 1:3 to obtain the zein solution.

[0022] The preparation method of biological particles is as follows:

[0023] A. Take bentonite and hydrochloric acid according to the mass ratio of 1:2, ultrasonically shake for 15 minutes, filter, and calcinate the filter cake at 700°C for 1 hour, collect the calcined products, crush them, pass through a 200-mesh sieve, and mix the sieved particles with 0.3mol / L glucose The solution was mixed according to the mass ratio of 1:4 and allowed to stand for 50 minutes, spray-dried, and the dried particles were collected for later use;

[0024] B. In terms of par...

Abstract

The invention discloses a preparation method of a degradable sand fixation agent and belongs to the field of sand fixation agents. The method comprises the steps of putting peat soil, glucose and water in a container for uniform mixing and standing, performing spray drying, collecting a dry product for ball-milling and sieving, collecting sieving particles, putting acetone, 1,4-butanediol, L-lactide and dibutyltin dilaurate in a reactor, using carbon dioxide for shielding, raising a temperature for reaction, cooling to a room temperature, collecting a reaction mixture, recovering acetone, collecting residue, putting the residue, methylbenzene, trimethylol propane trimethacrylate, toluene diisocynate, the sieving particles and a catalyst in a reaction kettle for stirring, adding triethanolamine, raising the temperature, continuing stirring, cooling to the room temperature, performing discharge, collecting a discharge product, filtering the discharge product to recover the catalyst, performing rotary evaporation to recover methylbenzene, collecting rotary residue, and uniformly mixing the rotary residue, cholla gum and biological particles to form the degradable sand fixation agent.

Description

technical field [0001] The invention belongs to the field of sand-fixing agents, and in particular relates to a preparation method of a degradable sand-fixing agent. Background technique [0002] Desertification is a major global ecological environment problem that mankind is facing at present, perplexing the survival and development of human society, and my country is one of the countries seriously endangered by desertification. The area of ​​desert and desertified land is 1.49 million km 2 , of which the area of ​​desertified land is 334,000 km 2 , which has seriously affected industrial and agricultural production, people's lives and human health, and the ever-increasing sandstorms and the expansion of desertified land have made the ecological environment worse, engulfing the living space of the Chinese nation, and causing serious damage to the national economy and social development. great harm. At the same time, there are often a series of ecological problems such as...
