Abstract
The invention belongs to the technical field of chemical synthesis, and specifically relates to a preparation method of polyether polyol for a coal mine reinforcing material. The polyether polyol is prepared from the following raw materials in parts by weight: 80-150 parts of an initiator, 50-100 parts of drainage oil, 1-2 parts of an amine catalyst and 80-120 parts of epoxypropane, wherein the initiator is one of ethylene glycol, propylene glycol, diethylene glycol and dipropylene glycol. The preparation method comprises the following steps: dissolving drainage oil in the initiator to dissolve the drainage oil to a homogeneous phase; pumping the amine catalyst; polymerizing epoxypropane in two steps; drying and dehydrating to obtain the polyether polyol. The preparation method provided by the invention is simple to operate, scientific and reasonable and low in cost. The prepared product can quickly permeate and expand in a fracture of a surrounding rock to form a tough netty structure with intersected branched slurry veins, so that the bearing capacity of the coal and rock mass is extremely enhanced, and the stability of the surrounding rock of a roadway is improved. The polyether polyol has good effects of sealing fractures and reinforcing and is a safe and efficient chemical reinforcing material.
Description
Technical field
The invention belongs to technical field of chemical synthesis, be specifically related to the preparation method of polyether glycol for the reinforcement material of a kind of colliery.
Background technology
As everyone knows, cement grouting material, poor stability poor as the colliery reinforcement material property noted and chemical grouting material have toxicity, pungency and expensive shortcoming.Therefore, the primary problem of grouting technique is studied the new injection material of development and the existing injection material of improvement in countries in the world as the present and the future.Slurry material development will be accomplished following 4 points: nuisanceless, diversity, weather resistance, valency are cheap.China is chemical grouting technology under phase early 1990s begins one's study coal mine, and has obtained greater advance.Colliery chemical grouting material now mainly contains:
1, Weir floating charge underfill material: Weir is floating is a kind of high molecular polymer;
2, Haas floating charge underfill material: Haas is floating is modified urea-formaldehyde resin solid state foam material;
3, De Keyin rock improvement material: De Keyin material belongs to modified Portland class injecting paste material;
4, fill in auspicious reinforcing: filling in auspicious reinforcing is that specialized designs is applied to two component injecting paste materials that coal and rock is reinforced.It is that specialized designs is applied to two component injecting paste materials that coal and rock is reinforced that Sai Rui reinforces.This product has high flame retardant, high strength, high cohesive force, and the feature such as temperature of reaction is low, perviousness is strong.Adopt pneumatic pump and hybrid gun that A component and B component are mixed and inject coal petrography by the volume ratio of 1:1, the superpolymer that reaction generates, together with coal petrography mortise, maintains the stability of Coal-body Structure.
