Abstract

The invention discloses adhesive impregnation liquid and an impregnation process for integrally weaving canvas, and belongs to the field of fiber adhesive impregnation liquid. The adhesive impregnation liquid comprises first impregnation liquid and second adhesive attaching liquid, wherein the first impregnation liquid comprises epoxy resin, isocyanate and deionized water; and the second adhesiveattaching liquid comprises water-soluble phenolic resin, butadiene-vinylpyridine copolymer latex, a surfactant and deionized water. The impregnation process comprises the steps of preparation of basecloth, preparation of the adhesive impregnation liquid and preparation of impregnated canvas. The technical scheme is improved aiming at the technical problems of insufficient strength of a canvas framework material, low impregnation degree of impregnation liquid and canvas, complex adhesive impregnation process and the like in the prior art, and compared with traditional RFL two-bath adhesive impregnation, the technical scheme disclosed by the invention has the advantages of simple adhesive impregnation process and sufficient adhesive impregnation amount of the canvas, so that the adhesive force with rubber in the later period is improved.

Description

technical field [0001] The invention relates to the field of fiber dipping liquid, in particular to a dipping liquid for integrally woven canvas and a dipping process thereof. Background technique [0002] Canvas is a thicker cotton or linen fabric, named after it was originally used for sails. Generally, plain weave is used, a small amount of twill weave is used, and multi-strand yarns are used for warp and weft yarns. Canvas is usually divided into two categories: coarse canvas and fine canvas. Coarse canvas, also known as tarpaulin, has good waterproof performance. Fine canvas is used to make labor protection clothing and its supplies. After dyeing or printing, it can also be used as shoe materials, luggage fabrics, handbags, backpacks, tablecloths, tablecloths, etc. At present, the common skeleton materials for canvas production include polyester, nylon and polyester fibers. Usually, canvas is also used to make conveyor belts together with rubber materials. However, o...
