Abstract
A method for preparing the color crystal soil able to slowly release water and nutrients and promote growth of plant includes mixing starch with water in alkaline condition, adding unsaturated vinyl monomer, dye, nutrients and antiseptic, and synthesizing step by step.
Description
Technical field:
The present invention relates to a kind of preparation method who promotes the colour crystal soil of plant growing, slow release long-acting.
Technical background:
Water-loss reducer is a kind of new function macromolecule water absorbent material, can absorb and keep the moisture of hundred times of himself weight even thousands of times, be widely used in agricultural, forestry, horticulture and flower and the transformation of desert ground etc., also be widely used in fields such as petrochemical industry, hygienic material.Colour crystal soil is mainly used in the horticulture and flower soilless culture and uses as a series of products of water-loss reducer.Crystal soil divides many colors, and maximum characteristics are health attractive in appearance, there is no any pollution, can be placed in the room Anywhere, can decorative beautifying environment, very strong sight is arranged again.In glassware, place it and plant the flowers of liking, believe and to bring more clean and tidy, more graceful makings to the room.The glassware of the bottom atresia of can also arranging in pairs or groups.Need not water at ordinary times, about two months also can take out plant, cleans root and quartzy mud respectively, and quartzy mud is drained, and implants again and suitably add nutrient solution to get final product.This has also fundamentally solved, and insect pest is fit to like cultivating personally the friends of flowers to the erosion of flower growth very much in the earth in the room.Like can selecting its tens kinds of color with dress up you of household of flowers, collocation mixes pleasing decorative effect surely arbitrarily.But there were many defectives in the colour crystal soil of Sheng Chaning in the past, mainly showed as the following aspects: the one, and the color of crystal soil adopts instant mode of dying, and used pigment is soluble in water, causes product to fade easily; The 2nd, lack nutrient component in the crystal soil, plant can cause growing bad because of malnutrition; The 3rd, the secretion that produces in the catabolite of crystal soil and the growing process can send unpleasant stink; The 4th, plant is in the moist environment for a long time, easily causes mashed root.
Technology contents:
The objective of the invention is to avoid the defective in the common crystal soil technology, nutritive element, preservative and dyestuff were added step by step in the synthetic suitable stage, and wherein the part dyestuff participates in reaction and reaches the purpose of preparing the colour crystal soil water-loss reducer that promotes plant growing, slow release long-acting.
For achieving the above object, the present invention has adopted following technical scheme:
A kind of promotion plant growing, the preparation method of the colour crystal soil water-loss reducer of slow release long-acting, it is characterized in that: in having the container of stirring, add 25-40% (weight ratio) water, 15-25% alkali, 5-15% starch, after when temperature is 40-60 ℃, stirring gelatinization 0.5-1.0hr, add 15-35% vinyl unsaturated carboxylic acid monomer, the nonacid unsaturated vinyl monomer of 6-12%, the 5-10% dyestuff, when being cooled to 20-25 ℃, add 0.05-0.5% crosslinking agent and 0.1-1.0% initator, and then when being warming up to 40-70 ℃, in container, react 0.5-1.5hr, add 3-8% nutriment and 0.001-0.01% preservative then, react 0.5-1.0hr again, can get the gel products that can directly use, but also after the drying, pulverize and make solid product.
As shown from the above technical solution, with starch after adding the water gelatinization under uniform temperature and the alkali condition, add unsaturated vinyl monomer, dyestuff, nutritive element, preservative, adopt the substep synthesis technique to make the native water-loss reducer product of the colour crystal that promotes plant growing then.Raw material used in the present invention is easily purchased, technology advanced person, simple; The prepared product water absorbing properties of the present invention is good, and water retention capacity is strong, and moisture and nutritive element discharge evenly; The present invention has solved shortcomings such as the product fugitive color that other polymerizations produced, mashed root, water conservation time weak point effectively.The prepared product of the present invention can be widely used in hotel, family, museum and some other public place gardening and decorate soilless culture usefulness.This colour crystal soil adopts the substep synthesis technique, has avoided above-mentioned the deficiencies in the prior art part, product can keep plant 2-3 month with interiorly need not water, nutrient solution, product is colour-fast, and is reusable more than 1 year.
