Problems solved by technology

Although the steel cord conveyor belt can achieve the purpose of flame retardancy, it has the disadvantages of short service life, long replacement time, and heavy weight.
The above shortcomings can be overcome by using all-chemical fiber fabric, that is, canvas as a flame-retardant belt with a core, but the flammability of canvas makes it necessary to carry out flame-retardant treatment.

Abstract

The invention aims to provide a dip solution of a flame retardant dipped canvas and a preparation method thereof. The dip solution and the preparation method have the beneficial effects that a two-bath dipping system is adopted; water-based latex is adopted in the first bath, namely the water dispersion solution of epoxy resin and blocked isocyanate; the water-based latex has the advantages of environment friendliness and safety; a dichloromethane organic solvent is adopted as styrene-butadiene latex of a dispersing agent in the second bath and can effectively improve the canvas and conveyor belt covering rubber bonding property; a blended aromatic brominated flame retardant and an antimonous oxide synergistic flame retardant system are adopted, so that the bonding strength of the canvas is improved and the flame retardance of the canvas is ensured while not affecting other indexes of the dipped canvas.

Description

technical field [0001] The invention relates to the technical field of sizing material for impregnating chemical fiber and synthetic fiber fabrics, in particular to an impregnating solution for flame-retardant impregnated canvas and a preparation method thereof. Background technique [0002] At present, as the requirements for the working environment of coal mines are increasing day by day, the safety requirements of conveyor belts as large items of production tools are becoming increasingly strict. Although the steel cord conveyor belt can achieve the purpose of flame retardancy, it has the disadvantages of short service life, long replacement time, and heavy weight. The above shortcomings can be overcome by using all-chemical fiber fabric, that is, canvas as a flame-retardant belt with a core, but the flammability of canvas makes it necessary to carry out flame-retardant treatment. Contents of the invention [0003] The present invention mainly aims at the above-mention...
