Method for preparing welding goggle material

Abstract

The invention discloses a method for preparing a welding goggle material, and belongs to the technical field of labor protection article preparing. The method includes the steps that polypropylene glycol and a pyrrole monomer serve as raw materials, ferric chloride hexahydrate serve as a catalyst, and polypyrrole nanometer particles are obtained; the polypyrrole nanometer particles are mixed with materials such as polycarbonate L-1225Z and an ultraviolet absorber UV360, the obtained premixed materials and liquid paraffin are mixed and screened, and compounded polycarbonate master batches are obtained; the master batches are subjected to injection molding through an injection molding machine, then an obtained compounded polycarbonate filter lens is cut and smoothed, the lens is finally washed with deionized water and dried, and the welding goggle material can be obtained. The welding goggle material prepared with the method can be subjected to light changing adjustment along with strong and weak change of arc light and distance to arc light of welding persons in the welding process, welding persons can clearly see weldments under all light ray conditions, and the flexibility and safety of the welding person operating are enhanced.

Description

technical field [0001] The invention discloses a preparation method of a welding goggle material, which belongs to the technical field of labor protection articles preparation. Background technique [0002] Welding technology is a common method for changing metal structures and connecting parts. With the continuous development of industrial technology, arc welding technologies such as manual arc welding and argon arc welding are more and more widely used. The technical level of the welder plays a decisive role in the welding quality. At the same time, accidents caused by personal violations are also common. [0003] During the welding process, the welding arc light is strong, which will cause great damage to the eyes of the welding personnel. Therefore, the welding personnel must wear welding goggles during the welding process to avoid the damage of the arc light to the eyes. At present, the welding goggles used by welding personnel include ordinary welding goggles and aut...

Problems solved by technology

[0005] The main technical problem to be solved by the present invention is that the current welding goggle materials only have two dimming states of light and dark, and the light transmittance is single in the dark state, and welding can only be performed at a short distance, which limits the operational flexibility of welding personnel The problem of providing a kind of preparation method of welding goggles material, this method is at first with polyacryl alcohol and pyrrole monomer as raw material, ferric chloride hexahydrate is catalyst to prepare polypyrrole nano-particle, and it and polycarbonate L- 1225Z, ultraviolet light absorber UV360 and other mixing treatment, the obtained premix and liquid paraffin are mixed and sieved to obtain composite polycarbonate masterbatch, the masterbatch is injection molded by injection molding machine, and then the obtained composite polycarbonate is filtered The light lens is cut, polished, and finally the lens is washed with deionized water and dried to obtain the welding goggle material. The welding goggle material prepared by the present invention can change with the intensity of the arc light during the welding process, and the welding The distance between the personnel and the arc light can be adjusted by dimming, so that the welding personnel can see the welding objects clearly under various light conditions, which enhances the flexibility and safety of the welding personnel's operation
