Urea-formaldehyde foam plastic cultivation substrate and preparation method thereof

Abstract

The invention relates to a urea-formaldehyde foam plastic cultivation substrate. The urea-formaldehyde foam plastic cultivation substrate comprises water-absorbing particles and a solid substrate, wherein a large number of gas micropores are uniformly dispersed in and on the surface of the solid substrate, and the water-absorbing particles are fixed on hole walls of the gas micropores or dispersed in gaps of the gas micropores. A preparation method of the urea-formaldehyde foam plastic cultivation substrate comprises the following steps of: performing polycondensation on urea and formaldehydeto obtain a urea-formaldehyde resin solution; preparing a foaming solution; stirring the foaming solution to produce a large amount of foam, then adding the urea-formaldehyde resin solution, continuously stirring, spraying super absorbent resin particles during the volume expansion process of materials, and stirring and foaming continuously for forming a urea-formaldehyde resin foam matter; and curing the urea-formaldehyde resin foam matter in a plastic mold, simultaneously fixing the super absorbent resin particles on the walls of cured foam pores or dispersing in the gaps of the gas micropores, and forming the urea-formaldehyde foam plastic cultivation substrate. The urea-formaldehyde foam plastic cultivation substrate disclosed by the invention has the advantages of simplicity in production and processing, convenience in mounting, easiness in transportation and capability of cutting and forming the shape according to requirements.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a urea-formaldehyde foamed plastic cultivation substrate and a cultivation method thereof. Background technique [0002] In recent years, with the improvement of living standards, people have higher and higher requirements for the greening level of living and living environment. Not only need the surrounding environment with pleasant scenery and full of plants, but also hope to create a comfortable living environment in the living room, especially eager to create a living environment for your family in the noisy city, including indoor, outdoor, balcony, patio, roof, passage, corridor or Inject green life into your own small garden. The requirements for improving the living environment, the demand for fresh and healthy vegetables, and the longing for urban farming, the extensive use of soilless cultivation techniques at home and abroad to meet these needs. [0003] For...

AI Technical Summary

Problems solved by technology

[0005] Most of the water-absorbing resins used for plant water retention are buried underground in arid areas to provide slow-release water for plants, or used in containers to provide water for fresh cut flowers, etc. There is little research on the use of water-absorbing resins in the fields of vegetable soilless cultivation and three-dimensional greening
