Embodiment Construction

[0036] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0037] Such as figure 1 The shown a kind of urea-formaldehyde foamed plastics cultivation substrate comprises urea-formaldehyde foamed plastics (1), and described urea-formaldehyde foamed plastics (1) is that air is involved in the solution of resin by means of agitation, making it into a uniform foam, and then After physical or chemical changes, it is stabilized into a foamed plastic solid. A large number of gas micropores are dispersed in the urea-formaldehyde foamed plastic to form a pore structure and distributed with superabsorbent resin particles (2). The superabso...

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...
