Abstract

The invention discloses a raw material composition of modified polyurethane material, and a preparation method and application thereof. The raw material composition comprises a component A and a component B, wherein A and B do not exist in the same component; the component A comprises 19-39% of polyoxypropylene polyalcohol, 60-80% of epoxyethane modified silicone polymer and 1% of metal catalyst; and the component B comprises 9.99999-19.99999% of polyether glycol, 80-90% of polyisocyanate and 0.00001% of storage stabilizer. The preparation method comprises the following steps: component A: mixing the polyether glycol, modifier and catalyst, stirring at 15-40 DEG C for 3-4 hours at the rate of 100-120 rpm; and component B: heating the polyether glycol to 80-100 DEG C, stirring, dehydrating and degassing in vacuum until the water content is less than 0.05%, cooling to 10-40 DEG C, adding the polyisocyanate, reacting at 80-85 DEG C for 2-3 hours, cooling to 10-40 DEG C, adding the storage stabilizer, and uniformly stirring. The raw material composition has the advantages of low reaction temperature, incombustibility, high reaction speed, favorable flowability and the like.

Description

technical field [0001] The invention relates to a raw material composition of a modified polyurethane material, a preparation method and application thereof. Background technique [0002] With the vigorous development of my country's mining industry, new large-scale underground mines have been put into production one after another, and the mining depth of old mines has gradually increased. However, geological structures such as faults, folds, and fissures are often encountered in the production process of coal mines, and large-scale roof caving and water inrush accidents are prone to occur. It seriously threatens the production safety of underground coal mines. There is an urgent need for technologies and products for stabilizing rock formations, curing cracked rock formations and crushed stones and other reinforcing materials and filling materials. Chemical grouting mainly includes polyurethane, epoxy resin, urea-formaldehyde resin, etc., and urea-formaldehyde resin has form...
