Preparation method of moisturizing nutritional covering material for bare soil and product thereof

Abstract

The invention relates to a preparation method of a moisturizing nutritional covering material for bare soil and a product thereof. The preparation method comprises the following steps of mixing plantstraw, water, urea and a straw fermenting agent, so as to ferment a straw organic fertilizer; mixing 1 / 3 of straw organic fertilizer, potato starch, polyethylene glycol 200 and glycerol, so as to obtain organic polyether polyol; adding toluene diisocynate, triethanolamine, organic silicone oil, organic bismuth, 1,4-butanediol and water into the organic polyether polyol, so as to obtain organic starch polyurethane foam; enabling 1 / 3 of straw organic fertilizer, ammonium persulfate, acrylamide, bentonite, expanded perlite and plyethylene glycol diacrylate to react, and adding 1 / 5 of organic starch polyurethane foam and ammonium hydrogen carbonate, so as to obtain a solid particle water retention agent; adding a slow-release fertilizer, water-absorbent resin, the remained straw organic fertilizer and the solid particle water-retention agent into the remained organic starch polyurethane foam; adding sodium alginate and water, and stirring, so as to obtain a finished product. The moisturizing nutritional covering material is used for preventing the dust fly and promoting the growth of vegetation, and can be biodegraded.

Description

technical field [0001] The invention relates to a preparation method and a product thereof for covering bare soil without vegetation growth, which is natural and safe, has good moisturizing and nutritional effects, and is conducive to rapid growth of vegetation. Background technique [0002] At present, a lot of dust will be generated on the land after urban demolition, many abandoned and unused land, and the bare land under construction, which directly affects the air quality. Now many construction workers use covering nets made of covering chemicals to cover these lands In order to achieve the effect of suppressing dust and beautifying the environment, it looks green in the distance, but it is not really green, and its effect of suppressing dust flying is also very general. It can not solve the defect of soil dust flying fundamentally. , resulting in a low level of urban greening, and the long-term problem of dust due to exposure and dirt cannot be solved. Even with tall ...

Problems solved by technology

However, halide dust suppressants are corrosive to metals; inorganic dust suppressants will increase ash content and easily lead to soil salinization; polymer water-absorbent resins can easily cause soil compaction, which is not conducive to the growth of plants; There are also some polymer dust suppressants that are not degradable and will cause secondary pollution to the environment
