Description

Technical Field

[0001] The invention relates to a sand-fixing conditioner, a preparation method thereof and application thereof in sand-fixing. Background Art

[0002] Due to the arid and semi-arid climate in Northwest China, the land has gradually lost its fertility and vitality, leading to desertification. Desertification has impacted people's lives. For example, the yellow sandstorms hinder travel, and the flying dust easily enters the human respiratory system, affecting health. Therefore, sand prevention and control are imperative.

[0003] Currently, the main methods of preventing and controlling sandstorms are crop planting and physical sheltering. However, this cannot completely curb the windy and sandy weather, which requires more wind-proof and sand-fixing measures in combination with sand prevention and control.

[0004] The market needs more windbreak and sand fixation measures to cope with soil desertification. Summary of the Invention

[0005] The invention provides a sand-fixing conditioner, a preparation method thereof, and application thereof in sand fixation, which solves the technical problem of providing a new wind-proof and sand-fixing means to cope with soil desertification.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions: A sand-fixing conditioner comprising a water-soluble protein, a moisturizing agent and transglutaminase; The sand-fixing conditioner is divided into aqueous solution and powder.

[0007] The water-soluble protein is one or more of water-soluble soybean protein, water-soluble fish protein, water-soluble feather protein and water-soluble yeast powder; The moisturizing agent is one or more of sorbitol, glycerin and polyethylene glycol; The mass ratio of water-soluble protein, moisturizing agent and transglutaminase is 70-94.5:5-20:0.5-10.

[0008] The aqueous solution further comprises an adsorptive solid; the mesh size of the adsorptive solid is ≥1200 mesh.

[0009] The adsorptive solid is one or more of molecular sieve, porous ceramics, talc and diatomaceous earth.

[0010] The preparation method of the sand-fixing agent is carried out according to the following steps: mixing water-soluble protein, moisturizing agent and glutamine transaminase to obtain a powdered sand-fixing agent; or Dissolving water-soluble protein, moisturizing agent and transglutaminase in water to obtain an aqueous sand-fixing conditioner; The mass ratio of water-soluble protein, moisturizing agent, transglutaminase and water is 5-30:0.5-2:0.05-3:65-95.

[0011] When the aqueous sand fixation agent contains adsorbent solids, follow the steps below: Add the dispersant, wetting agent and defoamer to water, mix well, add the adsorptive solid, and shear at a speed of 800 to 3000 r / min for 15 to 40 minutes to obtain a shear fluid; Dissolve the water-soluble protein in water to obtain a protein solution; Add the protein solution to the shearing solution and mix well to obtain the sheared protein solution; The glutamine transaminase is packaged separately to obtain the glutamine transaminase; Add moisturizer; The combination of shear protein liquid and transglutaminase is a sand-fixing agent; The adding of the moisturizing agent is adding the moisturizing agent into the shearing fluid; or Adding humectants to the egg white solution; or Adding a humectant to the sheared protein solution; or Adding a moisturizer to the transglutaminase; or Add moisturizer to the sand-fixing conditioner.

[0012] When the aqueous sand fixation agent contains adsorbent solids, follow the steps below: Add dispersant, wetting agent and defoamer to water, mix well, add adsorbent solid, and heat at a speed of 800-3000 r / min. Shearing is performed under the following conditions, and the shearing time is 15 to 40 minutes to obtain a shearing fluid; Dissolve the water-soluble protein in water to obtain a protein solution; Add the protein solution to the shearing solution and mix well to obtain the sheared protein solution; Add moisturizer; Adding transglutaminase to the sheared protein solution and mixing evenly to obtain a sand-fixing conditioner; The adding of the moisturizing agent is adding the moisturizing agent into the shearing fluid; or Adding humectants to the egg white solution; or Adding a humectant to the sheared protein solution; or Add moisturizer to the sand-fixing conditioner.

[0013] The mass ratio of dispersant, wetting agent, defoaming agent, adsorptive solid and water is 0.01-0.05:0.01-0.05:0.01-0.05: 10-25:73.5-89.7; The mass ratio of water-soluble protein to water is 5-25:75-95; The mass ratio of protein solution to shearing solution is 40-95:5-60; The mass ratio of sheared protein solution to transglutaminase is 98-99.9:0.05-2; The mass ratio of the moisturizing agent to the sand-fixing conditioner is 1-20:80-99.

[0014] The application of sand-fixing conditioner in sand fixation is to dilute the sand-fixing conditioner with water and then spray it on the surface of the sand; The dilution is such that the mass ratio of the sand-fixing agent to water is 1:20 to 500.

[0015] The invention has the following beneficial technical effects: 1) This application utilizes a combination of water-soluble protein, a humectant, and transglutaminase to effectively stabilize sand. Deserts, lacking vegetation and exposed to sunlight, experience large temperature swings between day and night, with higher temperatures during the day and lower temperatures at night. The sand-fixing conditioning agent prepared in this application utilizes the humectant to retain moisture while leveraging the high daytime temperatures of the desertified surface to enable transglutaminase to rapidly cross-link the water-soluble protein, forming a three-dimensional structure that further locks in moisture and fine sand, thereby achieving both sand fixation and soil conditioning.

[0016] 2) When preparing the aqueous sand-fixing agent, this application limits the mesh size of the adsorptive solids to ≥1200 mesh and requires shearing to obtain a shearing fluid. This is because water-soluble proteins themselves have a certain viscosity, which easily causes the adsorptive solids to aggregate, thus affecting the use effect. When transglutaminase rapidly cross-links the water-soluble protease, the adsorptive solids dispersed in the aqueous sand-fixing agent become condensation nuclei, which can increase the volume and weight after condensation, thereby better coping with wind-blown sand and achieving a better sand-fixing effect.

[0017] 3) This application designs aqueous solutions and powders because adsorbent solids cannot be added to powders, but can be added to aqueous solutions, and the effect is better after adding adsorbent solids. DETAILED DESCRIPTION

[0063] The beneficial effects of the present invention are further illustrated below in conjunction with test data: Experiment 1 1.1 Test location: Jingtai County, Baiyin City, Gansu Province.

[0064] 1.2 Experimental test: sand fixation effect (%).

[0065] 1.3 Test materials: Comparison 1 (except for not containing water-soluble yeast, all other contents are the same as those in Example 1), Comparison 2 (except for not containing mountain yeast, Comparative Example 3 (except for not containing transglutaminase, the others are the same as Example 1), Comparative Example 4 (except that the mesh size of the diatomaceous earth is 500 mesh, the others are the same as Example 3), Comparative Example 5 (except that no shearing fluid is prepared, but diatomaceous earth and water-soluble yeast powder are added to water to directly obtain protein liquid, and the combination of protein liquid and transglutaminase is the sand-fixing conditioner, the others are the same as Example 3), and the sand-fixing conditioners prepared in Examples 1 to 8.

[0066] 1.4 Test method: Choose a sunny day and pile sand of the same size on the same plot. The height of the sand pile is 50 cm. Each treatment corresponds to 40 sand piles, which are randomly matched. The sand fixation effect calculation formula is: E = ((q0-q1) / q0) * 100%, where E represents the sand fixation effect (%), q0 represents the sand transport rate at each height of the bare sand (g cm -2 min -1 ) and q1 represents the sum of the sand transport rates at each height of the sand fixation agent application. The sand transport rate was measured using a 15-hole stepped sand collector. While measuring wind speed, sand was collected from 10 types of sand barriers and a sand collector deployed in the open field. The sand inlet faced the main wind direction, and the collection time was one hour. The sand collector was 30 cm tall and divided into 15 layers, each 2 cm thick. The sand inlet of each layer measured 2 cm x 2 cm. The collected sand was weighed layer by layer using a 0.001g precision balance, and the sand transport rate was calculated in g·cm. -2 ·min-1; When using, use water to dilute the sand-fixing agent to a solid content of 0.4% to obtain the diluted sand-fixing agent. The dosage of the diluted sand-fixing agent is 50ml / pile.

[0067] Except for the experimental treatment, other operations were the same in this experiment.

[0068] 2 Results and Analysis Sand fixation effect (%) is shown in Table 1 Table 1

[0069] From the comparison of the data of Comparison 1, Comparison 2, Comparison 3 and Example 1, it can be seen that the water-soluble protein, the moisturizing agent and the transglutaminase interact with each other, and any change in any one of them will affect the use effect.

[0070] The diameter of the diatomaceous earth particles used in comparison 4 is large, which makes it difficult to disperse during shearing. The yeast powder is adsorbed on the surface, resulting in flocculation, so the effect is not good.

[0071] In contrast 5, the diatomaceous earth was not dispersed and was directly dissolved with the water-soluble yeast powder. The water-soluble yeast solution had a certain viscosity, which caused the diatomaceous earth to flocculate, so the effect was not good.

[0072] From the comparison of the data of Example 1, Example 2 and Example 3, it can be seen that under the premise of the same solid content, Example 3 with the addition of an adsorbent has the best effect. This may be because when glutamine aminotransferase quickly promotes the cross-linking of water-soluble proteases, the adsorptive solids become condensation nuclei, fixing more sand and increasing the volume and weight after condensation, thereby better coping with the blowing of wind on sand and achieving a better sand fixation effect.

[0073] It can be seen from the data of Examples 3 to 6 that the order in which the moisturizers are added does not affect the sand-fixing effect.
