Problems solved by technology

However, as a soil cultivation substrate substitute and improver, the effect is not ideal in practical applications. This is because the foam absorbs a large amount of water and is easily compacted during the process of treating the foam with a wetting agent, thus losing water retention.
Even if it is not treated with a wetting agent, because the foam itself is light, it is easy to be compacted during the process of grinding into granules, thereby destroying its water retention

Embodiment 1

[0035] Take 1 part of peat soil, add 0.2 parts of ethanol according to the volume ratio of wetting agent: peat soil = 1:5, spray the ethanol on the peat soil and stir to mix evenly. According to the volume ratio of peat soil: urea-formaldehyde foam particles = 1:2, add 2 parts of urea-formaldehyde foam particles and mix well.

[0036] The urea-formaldehyde foam composition obtained in this embodiment, as a cultivation substrate, is suitable for indoor shade plants, such as golden diamond, pothos, arrowroot, evergreen and the like.

[0037] The cultivation substrate obtained in the present example was used to cultivate the golden diamond and the pothos, respectively, for 5 months. The cultivation substrate did not lose water retention because it absorbed a large amount of water and was easily compacted, and the growth of the golden diamond and the pothos was in good condition.

Embodiment 2

[0039] Take 2 parts of peat soil, add 0.5 parts of phosphate surfactant according to the volume ratio of wetting agent: peat soil = 1:4, spray the phosphate surfactant on the peat soil and stir to mix evenly. According to the volume ratio of peat soil: urea-formaldehyde foam particles = 1:0.5, add 1 part of urea-formaldehyde foam particles and mix well.

[0040] The urea-formaldehyde foam composition obtained in this embodiment, as a cultivation substrate, is suitable for most plants, shrubs, herbs, and shade plants, such as golden leaf, duck foot wood, boxwood, privet, and Photinia fruticosa.

[0041] The cultivation substrate obtained in this example was used for cultivating Golden Leaf and Daffodil for 5 months respectively. The cultivation substrate did not lose water retention because it absorbed a large amount of water and was easily compacted. The growth status of Golden Leaf and Dracula good.

Embodiment 3

[0043] Take 2 parts of peat soil, add 0.2 parts of phosphate surfactant according to the volume ratio of wetting agent: peat soil = 1:10, spray the phosphate surfactant on the peat soil and stir to mix evenly. According to the volume ratio of peat soil: urea-formaldehyde foam particles = 1:0.5, add 1 part of urea-formaldehyde foam particles and mix well. Add and account for 40% washed sand of peat soil, phosphate surfactant and urea-formaldehyde foam particle gross weight, mix evenly.

[0044] The urea-formaldehyde foam composition obtained in this embodiment is suitable for planting trees as a cultivation substrate.

Abstract

The invention discloses a urea-formaldehyde foam composition and a preparation method thereof. The urea-formaldehyde foam composition is mainly formed by mixing urea-formaldehyde foam, peat soil and a wetting agent; the urea-formaldehyde foam is urea-formaldehyde foam particles with a diameter of 0.1 to 1.0 cm. Among them, the mixing volume ratio of peat soil and urea-formaldehyde foam particles is peat soil: urea-formaldehyde foam = 1:0.2~250. In the present invention, when the peat soil is pulverized and ground, the liquid wetting agent is sprayed on the peat soil in the form of a mist, stirred and mixed evenly, and then the peat soil or peat-like humus soil is ground into fine powder and then pulverized into granular urea-formaldehyde The materials of the foam are mixed evenly. When peat soil powder infiltrated with wetting agent and granular foam material are evenly mixed, the synthetic raw material not only has strong water retention, but also eliminates the weakness of the original foam material that is easy to be compacted.

Description

technical field [0001] The invention relates to the field of garden planting, in particular to a urea-formaldehyde foam composition and a preparation method thereof. Background technique [0002] Since the invention of urea-formaldehyde foam, it is mainly used as sound insulation and thermal insulation materials, and is widely used in construction, transportation, chemical industry, oil field, medical and health care, packaging and other industries. Urea-formaldehyde foam has also been tried in agricultural applications, such as as a foam plastic base for flower arrangement art, or as a carrier of wetting agent, which is ground into fine particles and added to the soil to enhance the water retention capacity of the soil, but the improvement of urea-formaldehyde foam The product has not yet gained widespread use as an alternative to soil cultivation. [0003] The product obtained by the traditional synthetic method of urea-formaldehyde foam has extremely strong hydrophobicit...
