Abstract

The invention relates to a high-specific-heat-capacity substance based electric welding protective plus material and a preparation method thereof. The high-specific-heat-capacity substance based electric welding protective plus material is prepared from an inflaming-retarding textile, a high-water-absorption coating composition and a water-repellency finishing layer. The preparation method of theelectric welding protective plus material comprises the following steps of applying the high-water-absorption coating composition to the front surface of an inflaming-retarding plus material, next, oven-drying for 1 min to 10 min at 120 DEG C, and baking for 1 min to 5 min at 160 DEG C, wherein the high-water-absorption coating composition is prepared from oily polyurethane, a cross-linking agent,high-water-absorption resin, a dispersant and lignin powder and the like; locally or fully applying a water-repellency finishing agent to the back surface of the front surface coated inflaming-retarding textile obtained in the former step; and before use, spraying or atomizing liquid water with an application amount of 100 g / m<2> to 300 g / m<2> to the high-water-absorption coating on the front surface. Through the way, an electric welding spark in contact with the plus material can be quickly extinguished after the surface of the electric welding protective plus material provided by the invention absorbs water; the heat is absorbed or quickly moved away; thus, the heat reaching a skin is reduced; and the purpose of protecting the skin from being burned is achieved.

Description

technical field [0001] The invention relates to the field of special protective functional fabrics, in particular to an electric welding protective fabric based on a high specific heat capacity material and a preparation method thereof. Background technique [0002] Electric welding is a general term for arc welding. It refers to a welding method that uses welding rods to melt the places that need to be connected between metal parts through an arc at high temperature. It is the most widely used welding method in industrial production. Theoretically speaking, the process of metal burning is the welding process. It uses the high temperature generated by the current short circuit to melt the base material (welding piece) and the filler (welding rod) to form a molten pool, which transitions into a weld after cooling. [0003] During electric welding, the electrode is used as one electrode of the circuit, and the weldment is the other electrode, and an arc is formed between the t...
