Abstract

The invention provides a high-temperature-resistance industrial canvas impregnation composition. The high-temperature-resistance industrial canvas impregnation composition id characterized by comprising a first bath composition and a second bath composition, and the first bath composition is prepared from, by weight, 6-15 parts of blocked isocyanate, 1.5-5.5 parts of an epoxy compound and 92.5-140.5 parts of soft water; the second bath composition is prepared from, by weight, 0.3-4.5 parts of a sodium hydroxide solution, 16.2-26.8 parts of formaldehyde, 11-22 parts of resorcinol, 50-150 partsof latex and 180-280 parts of deionized water. The high-temperature-resistance industrial canvas impregnation composition has the advantages of being resistant to high temperature, acid and alkali andhighly resistant to wear and improves the performance of impregnation liquid.

Description

technical field [0001] The invention relates to a dipping solution formula, in particular to a dipping formula for high-temperature-resistant industrial canvas, which belongs to the technical field of industrial cloth. Background technique [0002] Glue dipping means that the fabric passes through the glue dipping tank, so that the fabric fibers are soaked in the glue, so as to improve the bonding force between the fabric and the glue. Dipping can make the surface of rayon, synthetic fiber and glass fiber cord smooth. After dipping, it can significantly improve the adhesion of rubber and fiber. The commonly used immersion solution is an aqueous emulsion of natural latex and resorcinol formaldehyde resin. The glue service equipment includes a stain tank, a drying room, a hot sheet and a coiling device, which can also be connected with a calender to form a joint production line of dipping, glue application and glue wiping. The dipping solution can improve the private adhesio...
