[0003] Chinese invention patent CN103694672 introduces a high flame-retardant, low-temperature two-component filling material for coal mines and its preparation method. The invention uses the principle of physical foaming to make the foaming agent generate heat during the reaction of polyurethane materials to volatilize and then Foam is formed, but the low-boiling foaming agent added in the invention will affect the safety performance of the material due to the high temperature, especially in high-temperature and high-gas mine applications and cause danger during transportation
Chinese invention patent CN103627136A introduces a kind of polymer foam material for coal mine filling and sealing. Problems such as irritating gas and high formaldehyde content have been restricted

Abstract

The invention provides a silicate modified polyurethane foam material, as well as a preparation method and an application method thereof, relates to a combination adopting an organic polymer compound as a base material, as well as a preparation method and an application method thereof, particularly relates to a combination adopting polyurethane as the base material, as well as a preparation method and an application method thereof, and aims to provide a silicate modified polyurethane foam material which is free from a foaming agent and an organic fire retardant, easy to get raw materials, low in reaction temperature, safe and stable, as well as a preparation method and an application method thereof. The foam material comprises a component A and a component B, wherein the component A comprises polyisocyanate and a toughening agent; the component B comprises a silicate aqueous solution, polyether glycol, a foam stabilizer and a catalyst. The foam material does not contain a foaming agent or an organic fire retardant, and is low in reaction temperature, safe and stable; the preparation method and the application method are simple and easy to operate; the foam material can be used in the fields of cavity filling of coal mine underground collapsed zones, gas prevention, air leakage prevention, airtightness, leakage stopping of water areas and the like.

Description

technical field [0001] The present invention relates to a composition synthesis, preparation method and application method based on an organic polymer compound, in particular to a composition synthesis, preparation method and application method based on polyurethane. Background technique [0002] With the development of the coal mining industry, roof fall often occurs in the process of coal mining, so measures such as filling and repairing the roof fall area are required before coal mining can be carried out again. At present, the filling and sealing materials used in coal mine high-rise filling, upper and lower corner filling, and underground roadway working faces are mainly phenolic resin foaming materials and polyurethane resin foaming materials. The former has problems such as high corrosiveness of raw materials, irritating odor when foaming, high formaldehyde content, and crisp foam. The latter has high reaction temperature. In order to meet the flame retardant requirem...
