Description

It is slow（Control）Release, multielement degradable artificial Nutrition Soil

The present invention relates to a kind of chemical synthesis matrix, delay（Control）Release, multielement degradable artificial Nutrition Soil, belong to agrochemical field and field of polymer composite material.

Background technology

The solid matrix of soilless culture has many kinds, including rock wool, vermiculite, perlite, sand, gravel, turf, rice husk, coconut palm chaff, sawdust, bacteria residue etc., these matrix are added after nutrient solution, can be as soil to plant offer O2, H2O, nutrient and the support to plant, in place of some shortcomings that pure water training can be made up simultaneously, such as poor aeration, it is impossible to moisture condition of regulation supply root system etc.;Chemical synthesis matrix is also known as Artificial Soil, is a kind of new product that last decade is developed, and it is with organic chemicals（Such as ureaformaldehyde, polyurethane, phenolic aldehyde）Make raw material, artificial synthesized novel solid matrix.Its host component can be UF foamed plastics, polyurethane foam plastics, polysiloxane foamed plastics, phenolic foam, Polyvinyl Formal Foam Plastic, any or several mixtures of polyimide foam in porous plastics, it can also be the class strong water absorption function agent of starch polypropylene resin one, allow to penetrate into non-stomata plastics even perlite in right amount when using;The Artificial Soil for obtaining more application in production at present is UF foamed plastics, it is a kind of soilless cultivation matrix for obtaining industrial urea-formaldehyde foam after becoming privileged modification, it is a kind of tool loose structure, diameter≤2cm, shaggy foam piece, with the physicochemical property close with soil, pH is 6~7, and is easily adjusted.Unit weight is 0.01~0.02g/cm3, and total porosity is 827.8%, and macrovoid is 101.8%, and fine pore is 726.0%, gas-water ratio 1：7.13, saturated water adsorptive value has 20%~30% hole-closing structure up to 10~60 times or more of own wt, even if therefore still have large quantity of air hole when being saturated with water, be adapted to plant root growth, solve the oxygen deficit problem in suspension culture.Can 100% ground individually substitute soil be used for long-term serike, can be also used in mixed way with other foamed plastics or perlite, vermiculite, graininess rock wool etc.;But, the UF foamed plastics matrix produced at present only contains nitrogen, can not still realize multielement or full element nutrition, it is impossible to meet plant growth needs.Plant also needs to the later stage during UF foamed plastics matrix growth is developed and repeatedly applies other elements chemical fertilizer, and repeatedly fertilising is difficult and inequality brings adverse effect to plant growth;In addition, traditional UF foamed plastics matrix synthesis cost is higher.It is nekal that UF foamed plastics matrix, which synthesizes all expanding foam solution Main Ingredients and Appearances, also known as：Pull open powder, not only price is high, and toxic, and people is known from experience and damaged.Another Main Ingredients and Appearance of expanding foam solution uses phosphoric acid completely, can cause acid too strong, toxic to plant..

The content of the invention

The present invention delays in view of the above-mentioned problems, provide a kind of chemical synthesis matrix（Control）Release, multielement degradable artificial Nutrition Soil technology.Foam is mixed into using Organic plant nutrient powder, nitrification inhibitor and urease inhibitor, pollopas liquid, Novel foaming liquid and micro polynary fertilizer liquid and fills pressure one-shot forming.It is overall process Environment-friendlynon-toxic non-toxic, pollution-free, with low cost, natural degradation under field conditions (factors).Prepared by following methods：（1）Ureaformaldehyde expanded material is constituted：Organic plant powder and multielement powder chemical fertilizer 35-70%wt, expanding foam solution 5-25%wt are special, urea formaldehyde resin liquid 25-60%wt（2）Special urea formaldehyde resin liquid composition：Urea 15-60%wt, polyalcohols 2-5%wt, amine（Nitrification inhibitor）1-3%wt, formaldehyde（37%）30-80%wt.（3）Expanding foam solution is constituted：Powder physical blowing agent 5-15%wt, combines acids 15-35%wt, phenols（Urease inhibitor）5-20%wt, element fertilizer aqueous solution 30-80%wt;Preparation technology：（1）, Organic plant nutrient powder is put into special powder machine（Pulverizer）Powdered processing is carried out, fineness is 60-80 mesh.（2）, urea, formaldehyde, polyalcohol and amine（Nitrification inhibitor）25-40 DEG C is stirred 10-30 minutes after mixing, and rotating speed 120r/min can be prepared by special urea formaldehyde resin liquid.（3）, the selected element fertilizer of formula is dissolved in water, be sufficiently stirred for 10-15 points, aqueous fertilizer solution can be made in rotating speed 120r/min.（4）, physical blowing agent, combine acids, phenols, aqueous fertilizer solution are sufficiently stirred for 10-15 points, and special foam can be made in rotating speed 300r/min.（5）After Organic plant nutrient powder, special urea formaldehyde resin liquid, expanding foam solution mixing, foamed slurry can be made in rotating speed 400r/min.（6）Squeeze pressure 50-100kg/cm2,40-60 DEG C of temperature, time 1-2h, an extrusion forming.
