Abstract

The invention discloses a high-temperature-resistant industrial canvas gum-dipping formula. The formula comprises a first bath formula and a second bath formula, wherein the first bath formula comprises, in parts by weight, 16-20 parts of blocked isocyanate, 6.4-8.7 parts of an epoxy compound and 147.5-160.5 parts of soft water; and the second bath formula comprises, in parts by weight, 5-7 partsof a sodium hydroxide solution, 27-30 parts of formaldehyde, 23-28 parts of resorcinol, 152-180 parts of latex and 120-150 parts of deionized water. The invention provides the high-temperature-resistant industrial canvas gum-dipping formula which enables the heat resistance, the corrosion resistance, the pressure resistance and the fatigue resistance of industrial cloth to be good.

Description

technical field [0001] The invention relates to a formula for dipping liquid, in particular to a formula for dipping high-temperature-resistant industrial canvas. Background technique [0002] Plastic is an important organic synthetic polymer material, which is widely used. Since the advent of plastic products in the 20th century, it has been dipped. The fabric is soaked in the glue through the glue bath to improve the aging of the fabric and the glue. force. Dipping can make the surface of rayon, synthetic fiber and glass fiber cords smooth, and the adhesion between rubber and fiber can be significantly improved after dipping. The commonly used dipping solution is the water emulsion of natural latex and resorcinol formaldehyde resin. The glue service equipment includes a stain tank, a drying room, a thermal stretching and a coiling device, and can also be connected with a calender to form a joint production line of dipping, glue application, and glue wiping. The dipping ...
