Degradable foam composition for seedling raising or flower arrangement, and manufacturing method and application thereof

Abstract

The invention relates to the field of plant cultivation media, and particularly provides a degradable foam composition for seedling raising or flower arrangement. The degradable foam composition for seedling raising or flower arrangement is prepared from the following raw materials: phenol and polyformaldehyde in a mole ratio of 1:(1.4-2.5), water (24mL for every mole of phenol), urea (accounting for 10-25 wt% of the phenol), pulp board (accounting for 6-15 wt% of the phenol), starch (accounting for 6-15 wt% of the phenol), and 10 wt% polyvinyl alcohol (accounting for 2-15 wt% of the phenol). The invention also provides a preparation method and application of the degradable foam composition for seedling raising or flower arrangement. The reaction speed of the preparation method is greatly higher than that of the traditional method, and no wastewater is generated in the whole process. The free formaldehyde content and free phenol content of the prepared product are lower than the national standard, so the product is completely harmless; and the seedling raising container or flower mud prepared from the degradable foam composition is suitable for demands of plants for physical properties of the nutrient and medium.

Description

technical field [0001] The invention relates to the field of plant planting substrates, in particular to a degradable foam composition for seedling raising or flower arrangement and its manufacturing method and application. Background technique [0002] At present, the foam material composition that is used for plant seedling cultivation, preservation, growth, especially prolonging the life of flowers, keeping flowers fresh for a long time, and helping the growth of flowers is also called flower mud, and most of them belong to phenolic foam compositions. This foam material composition has a high porosity, crispness, breathability, and contains hydrophilic substances inside. It has good water absorption and water retention, making it a flower arrangement foam material composition widely used in domestic and foreign flower markets. It has beautification and appreciation effects. The preservation of fresh flowers for long-distance transportation is of special value. With the i...

AI Technical Summary

Problems solved by technology

[0011] 2.1 Boiler steam is used for heating, which has high energy consumption, low efficiency and serious pollution

Harmful substances in wastewater seriously endanger the environment and are difficult to treat

[0013] 2.3 At present, the flower mud foam produced by many enterprises has high content of free phenol and free formaldehyde

In terms of quality, the flower mud foam has relatively high hardness, crispness, dregs, inelasticity, and high density, about 35-40kg / m 3 , high production costs

[0014] 2.4 The produced foam does not degrade, it is difficult to handle, and it is harmful to the environment

[0015] 2.5 At present, there is no phenolic foam composition product that can be used for seedling cultivation in China. Although some large flower mud manufacturers in China have tried many times, they have not been successful.
