Abstract

The invention aims at providing a polyurethane reinforced material for inorganic modified ores and a preparation method thereof. The material is prepared by polymerizing components A and B. The component A is prepared from the following substances in percentage by mass: 31-57% of polyether polyol, 10-32% of polyester polyol, 1.0-14% of an inorganic modifier A, 1.0-11% of an inorganic modifier B, 0-1.8% of a foam stabilizer, 1.2-2.0% of a solubilizer, 0-35% of a foaming agent, 0.4-2.6% of a catalyst and 10-30% of a flame retardant; the component B is prepared from the following substances in percentage by mass: 50-75% of polymethylene polyphenyl polyisocyanate, 10-20% of diphenyl-methane-diisocyanate and 10-30% of a compound modifier. By adding the inorganic modifiers and optimizing the formula, the flame retardance of a conventional polyurethane material is improved, the reaction temperature of the material used is greatly reduced, and the potential safety hazard of the material in the using process is eliminated.

Description

Technical field [0001] The invention belongs to the field of polyurethane materials, and specifically relates to an inorganic modified mineral polyurethane reinforcement material and a preparation method thereof. Background technique [0002] In the process of underground mining and excavation in coal mines, roof management is a key part of safe and normal production. The roof fall and slabs caused by broken coal and rock masses have always been an unavoidable technical problem in mine production. Rockfalls are prone to accidents, so roadways need Reinforcement treatment. In addition, as the mining depth increases, the water inflow in the mine increases, the water content in the broken coal rock is large, and the roof has water dripping, making roof management more difficult. According to statistics, extremely broken, water-rich and water-sprinkling coal and rock masses account for about 30% of the total coal mining face and roadway engineering. There is an urgent need to develo...
