Abstract

The invention relates to a preparation method of electric-welding protective clothing fabric with a graphene coating and the prepared electric-welding protective clothing fabric. According to the preparation method, a graphene solution is sufficiently dispersed and then is added to a dye-fixing agent, and the mixed solution is sufficiently stirred, so that a graphene mixed solution is obtained, wherein raw materials comprise 97%-70% by weight of the graphene solution and 3%-30% by weight of the dye-fixing agent; the prepared graphene mixed solution is applied to flame-retardant base cloth by atextile coating finisher, the fabric coated with the graphene mixed solution is dried at the drying temperature of 75-95 DEG C for 5-30 min, and the coating quantity of the graphene mixed solution is1%-10% of the weight of the flame-retardant base cloth. The prepared electric-welding protective clothing fabric with the graphene coating has an excellent function of preventing temperature rise caused by dripping of molten metal.

Description

technical field [0001] The invention belongs to the technical field of textile product manufacturing, and in particular relates to the textile fabric processing technology with protection function. More specifically, the present invention relates to a method for preparing an electric welding protective clothing fabric with a graphene coating and the prepared electric welding protective clothing fabric. Background technique [0002] In my country, nearly 2 million people are engaged in electric welding. Welding workers, especially those who perform upward welding operations in narrow spaces, are faced with physical damage from molten metal. [0003] Existing electric welding protective clothing fabrics are mainly flame-retardant pure cotton fabrics, and high-grade electric welding protective clothing using leather or aramid fabrics are also available, but the price is very expensive. In order to prevent the molten metal produced by the electric welding operation from spilli...
