Urea formaldehyde-acrylic acid compound culture substrate and method for preparing same

Abstract

The invention provides a urea formaldehyde-acrylic acid compound culture substrate and a method for preparing the same. The urea formaldehyde-acrylic acid compound culture substrate comprises resin fibers, water-absorbing particles and a solid substrate, wherein the resin fibers are doped in the solid substrate, a lot of gas micropores are distributed in and on the surface of the solid substrate, and the water-absorbing particles are fixed on the pore walls of the gas micropores or dispersed in the gas micropores. The preparation method comprises the steps of hot-melting acrylic acid resin, blowing and pulling the melted acrylic acid resin to obtain resin fibers, and winding the resin fiber to form a flocculent structure; and putting the molded acrylic acid resin fiber in a mold in advance, squeezing foaming matters into the mold to obtain the mixture, curing the mixture in the mold, and simultaneously fixing the high-water absorption resin particles on the foam pore walls or dispersing the high-water absorption resin particles in the gas micropores to form the urea formaldehyde-acrylic acid compound culture substrate material. The urea formaldehyde-acrylic acid compound culture substrate has the advantages of simple production procedure, no toxin, no pollution, environment friendliness and the like, and is convenient to use and transport.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a urea-acrylic acid composite cultivation substrate and a preparation method thereof. Background technique [0002] With the development of human beings, the advancement of science and technology, and the deterioration of the environment, human beings are paying more and more attention to protecting the environment, and they are more and more eager to fill the living environment with green life. There are many buildings in the city, and the green landscape is also developing into a three-dimensional space. The process of urbanization has caused many people to leave the land, so many people pursue pastoral gardens. The increasingly serious food problem also forces people to find ways to grow vegetables for family self-sufficiency. At present, most of them use soilless cultivation to deal with these problems. [0003] At present, the three-dimensional greening methods u...

AI Technical Summary

Problems solved by technology

Water-absorbing resin has not been used in three-dimensional greening, and there is no fixed-shaped cultivation substrate in the three-dimensional cultivation field that can directly grow plants on it, and less use of other auxiliary materials such as fixed substrate components and containing substrates utensils and other materials
