Abstract

The invention provides a single-component polyurethane foam joint mixture and a preparation method thereof, and is characterized in that the single-component polyurethane foam joint mixture comprises the following raw material components: 7-11 parts of mixed polyether, 2-4 parts of a foam stabilizer, 36-42 parts of seed wrapping wax, 1-3 parts of a catalyst, 1.5-4.5 parts of a bactericide, 2-4 parts of an insecticide, 1.5-4.5 parts of a rooting agent, 19-23 parts of polymerized MDI, and 20-24 parts of a propellant. The invention has the advantages that: 1, the product adopts a sterilization insecticide, so that corresponding agricultural crop plants are prevented from being damaged by bacteria, mildewing and diseases and pests; 2, the rooting agent is added, so that plant root growth is promoted, plants can absorb nutrients, and healthy and strong growth of the plants is promoted; 3, the slow-rebound polyether polyol and the delayed catalyst have a synergistic effect, a propellant with a slow volatilization speed is preferably selected, and the post-foaming effect is obvious; and 4, the seeds are coated with paraffin, thereby being environment-friendly, non-toxic and beneficial to improving the fertilizer utilization rate. The invention also discloses a preparation method of the single-component polyurethane foam joint mixture.

Description

technical field [0001] The invention belongs to the field of polyurethane foam gap fillers, and particularly relates to a single-component polyurethane foam gap filler for rooting agriculture, post-foaming, sterilization and insect removal, and a preparation method thereof. Background technique [0002] The full name of polyurethane foaming agent is one-component polyurethane foam caulking agent, commonly known as single-component foaming agent, PU-Foam, PU caulking agent, etc. It is a modern product of the cross-combination of aerosol potting technology and polyurethane foam technology. Specifically, it is a special polyurethane product filled with one-component polyurethane prepolymer, foaming agent, catalyst and other components in an aerosol can. When the material is sprayed from the aerosol can, the foamed polyurethane material will expand rapidly and react with the air or the gaseous water in the contacting matrix to form a foam. The cured polyurethane foam caulking a...
