Example Embodiment

[0056] Example 1:

[0057] Put 60020kg of polyethylene glycol; 20016kg of polypropylene glycol; 4kg of vinyl polymer grafted polyether polyol; 0.5kg of dibutyl phthalate into a high-pressure reactor and dehydrate it for 2 hours at 90-100kPa and 100°C. After cooling, add 50kg of natural adhesive mixture and 0.4kg of dibutyltin dilaurate; stir, pass inert gas protection, heat to about 85°C, and react for 3h; finally add 5kg of adsorbent white carbon black, 4kg of calcium oxide, and stir well , cooling down and discharging, and preparing it into an adhesive for later use. Add 1kg of industrial gelatin to 10kg of decomposed branches, leaves, peat, coconut bark, and the mixture in a wet state, stir at a high speed of 35 degrees, and then stand still for 1 minute, then add 3kg of self-made adhesive at a high speed of 40-50 degrees Stir for 2 minutes, then pour into the mold and take out the mold.

Example Embodiment

[0058] Example 2:

[0059] Put 60018kg of polyethylene glycol; 20018kg of polypropylene glycol; 18kg of vinyl polymer grafted polyether polyol; 2kg of dibutyl phthalate into the autoclave, dehydrate for 3 hours at 90~100kPa, 100℃, and cool Finally, add 40kg of natural adhesive mixture and 0.4kg of dibutyltin dilaurate; stir, pass inert gas protection, heat to about 85°C, and react for 3h; finally add 3kg of adsorbent white carbon black, 3kg of calcium oxide, and stir well. The temperature is lowered and the material is discharged, and it is prepared into an adhesive for future use. Add 1kg of natural gum to 10kg of decomposed straw, peat, coconut bark, and the mixture in a wet state, stir at a high speed of 35 degrees, and then stand still for 1 minute, then add 3kg of self-made adhesive and stir at a high speed of 40-50 degrees for 2 Minutes, then pour into the mold and take out the mold.

Example Embodiment

[0060] Example 3:

[0061] Put polyethylene glycol 600: 24kg; polypropylene glycol 200: 24kg; vinyl polymer grafted polyether polyol: 6kg; Dehydrate for 3 hours, add 30kg of natural binder mixture and 0.45kg of dibutyltin dilaurate after cooling; stir, pass inert gas protection, heat to about 85°C, and react for 3 hours; finally add 2.5kg of adsorbent white carbon black, calcium oxide 4kg, fully stirred, cooled and discharged, prepared as adhesive for later use. Add 1kg of dextrin to 10kg of decomposed straw, peat, branches, leaves, and the mixture in a wet state, stir at a high speed of 35 degrees, and then stand still for 1 minute, then add 3kg of self-made adhesive and stir at a high speed of 40-50 degrees for 2 Minutes, then pour into the mold and take out the mold.

Abstract

The invention discloses a soilless culture substrate formula used for vertical greening, and a production method therefor. The production method comprises: weighing and adding a mixture of multi-hydroxyl ethers and a plasticizer, namely dibutyl phthalate into a high-pressure reaction kettle; then, adding a natural binder and a catalyst into the high-temperature reaction kettle with stirring, and introducing inert gas for shielding; finally adding an adosrbent with sufficiently and uniformly stirring, and discharging, thereby preparing a binder for later use; in the presence of an adhesive added in a wet state, uniformly stirring decomposed straws, grass carbon, coconut tree peel, coconut shells, branches and tree leaves at high speed to obtain a mixture, then, standing the mixture, adding a self-made binder into the mixture with stirring, pouring the mixture into a mould to form, and discharging the mixture out of mould. Polyethylene glycol 600 with molecular weight of 570-630, polypropylene glycol 200 with molecular weight of 180-220, and polymer polyol are matched in proportion, so that the soilless culture substrate formula can be suitable for splicing most of cellulose with different molecular weights; pores of a formed three-dimensional net-shaped structure are especially suitable for storing water molecules, so that water absorbing capacity of the whole substrate can be greatly improved, the gravity action can be overcome to certain extent, and the substrate is suitable for vertical greening.

Description

technical field [0001] The present invention relates to nutrient carrier, more specifically, it relates to a kind of soilless cultivation substrate formulation and its production method for vertical greening. Background technique [0002] Soilless cultivation uses light materials such as peat or forest leaf humus and expanded vermiculite as the seedling substrate to fix the plants, allowing the plant roots to directly contact the nutrient solution, and adopts the modern seedling technology of mechanized precision seeding for one-time seedling formation. The selected seedling tray is divided into compartments, sow one seed in one compartment, and one plant in one room for seedlings. The root system of the seedlings and the substrate are intertwined with each other. nursery. [0003] At present, the Chinese patent with the application number CN200810102818.9 on the market discloses a root nutrition carrier, a preparation method and its application. Its main components are com...
