Abstract

The invention discloses a flame-retardant conveying belt covering adhesive for a mine and a preparation method thereof. The flame-retardant conveying belt covering adhesive disclosed by the invention is added with nanometer magnesium hydroxide subjected to modification treatment in a preparation process, belongs to an environment-friendly green fire retardant and can play a high-efficiency smoke inhibition role; compared with a similar inorganic flame retardant, the flame-retardant conveying belt covering adhesive disclosed by the invention has a specific cooling technology, can promote the generation of a noncombustible compound and play a heat conduction and heat radiation obstructing role without corroding processing equipment, is low in price and low in production cost, and solves the problems of low extensibility and higher abrasion of the traditional covering adhesive and the problems of abrasion resistance and heat resistance especially through added superfine andalusite powder, thereby greatly prolonging the service life of a conveying belt.

Description

technical field [0001] The invention relates to a special material for conveyor belt covering glue, in particular to a mine-used flame-retardant conveyor belt covering glue and a preparation method thereof. [0002] Background technique [0003] The roadway transportation (also known as trough transportation) of the mining face in the coal mine is widely used in the transportation mode of the belt conveyor. According to the different types of covering rubber, the conveyor belts used in coal mines are currently divided into two categories: rubber surface conveyor belts (PVG) and plastic conveyor belts (PVC). Regardless of PVG conveyor belt or PVC conveyor belt, in order to improve the flame retardant performance of the cover rubber of the flame retardant conveyor belt, a large amount of flame retardant must be added to the rubber formula, and the added flame retardant will reduce the performance of the cover rubber, elongate The wear rate is low, the wear is large, especial...
