Abstract

The invention belongs to the technical field of hydrophilic agents, and particularly, relates to a preparation method of a hydrophilic agent for agricultural rock wool. The preparation method specifically comprises the following steps: S1, taking 30-40% by weight of polyether modified silicone oil, 20-35% by weight of methylallyl alcohol polyoxyethylene ether, 15-20% by weight of diacetone alcohol, 1-2% by weight of a dispersing agent, 0.5-1.5% by weight of sodium alginate and the balance being pure water for later use. The components of the polyether modified silicone oil and the methyl allylalcohol polyoxyethylene ether can improve the water absorption of the agricultural rock wool; the surface tension and the hydrophilic stability of the hydrophilic agent are improved through the sodium alginate and the diacetone alcohol; due to the use of the dispersing agent, the dispersity of the hydrophilic agent is better, sufficient dissolution is achieved, the rock wool has high water-retaining property, when the rock wool is used, the hydrophilic agent is directly sprayed on a rock wool base material in a spraying mode, the purpose of enhancing the hydrophilicity of the rock wool is achieved, and the agricultural rock wool has high hydrophilicity, high hydrophilic long-term stability and high water-retaining property.

Description

technical field [0001] The invention relates to the technical field of hydrophilic agents, in particular to a method for preparing a hydrophilic agent for agricultural rock wool. Background technique [0002] Agricultural rock wool is a green and environmentally friendly planting substrate. It is made of basalt, dolomite, limestone and coke after melting and spinning at a high temperature of 1600 degrees Celsius. It is easy to plant and manage, and has been widely used in Europe, the Middle East, and the United States. In the 1880s, it was first introduced into China by the Suzhou Academy of Agricultural Sciences and carried out planting research. At that time, domestic rock wool production and related additives failed to keep up, so it was finally given up. [0003] In recent years, domestic rock wool production and manufacturing have been greatly developed, and agricultural rock wool has gained attention as the next growth point of rock wool production and sales. [000...
