Vegetable gelatin adhesive for spray seeding and preparation method thereof

Abstract

The invention belongs to the field of ecological engineering, and relates to a pulp mixture additive used in spray seeding and coverage planting construction in ecological restoration engineering, particularly a vegetable gelatin adhesive and a preparation method thereof. The vegetable gelatin adhesive is prepared from the following raw materials in percentage by weight: 90-94.5% of plant seed gelatin powder and 5.5-10% of additives, wherein the additives comprise 0.5-2% of initiator, 1-3% of diffusant, 2-4% of inhibitor, 1-3% of defoaming agent and 1-3% of activating agent. The plant seed gelatin powder is separated and extracted from carob seed, fenugreek, guar, gleditsia sinensis, wild gleditsia sinensis, Tara or Sesbania plant seed; the initiator is potassium persulfate; the diffusantis sodium tripolyphosphate or sodium phosphate; the inhibitor is salicylic acid; the defoaming agent is dimethyl polysiloxane; and the activating agent is sodium sulfide or sodium carbonate. The vegetable gelatin adhesive is prepared from completely degradable raw materials, has the advantages of high environment affinity, high water solubility, low viscosity in wet state, high adhesive strength,high affinity with materials and high temperature adaptability, and has the functions of nutrition and soil moisture retention.

Description

technical field [0001] The invention belongs to the field of ecological engineering, and relates to a slurry mixing additive—vegetable glue adhesive—used in ecological restoration engineering for spraying and covering planting construction and a preparation process thereof. Background technique [0002] In the late stage of infrastructure construction such as highways, reservoirs, and power stations, vegetation restoration on exposed high and steep slopes is an important task. In modern vegetation restoration ecological projects, mechanized planting construction is often used, such as spraying machinery, seeds, soil stabilizers, fertilizers, covering materials, adhesives and water are fully mixed according to a certain ratio, and then used The spray gun sprays the mixture evenly onto the soil surface. The mixture forms a film-like structure on the soil surface, supplemented by other covering materials to protect it, which can effectively prevent rainwater erosion, is conduc...

AI Technical Summary

Problems solved by technology

[0006] The currently widely used adhesives in China are polymer compound products, which are not easy to degrade. After being applied to the soil, they tend to remain in the soil environment and have an adverse effect on the root growth of subsequent crops.

and cause varying degrees of damage to the soil

Natural vegetable glue can degrade and meet the requirements of ecological restoration, but the bonding strength and performance stability are poor
