Water-based welding anti-spatter agent and preparation method thereof

Abstract

The invention discloses a water-based welding anti-spatter agent and a preparation method thereof, and belongs to the technical field of metal welding anti-spatter chemical additives. The invention provides the technical scheme points that the water-based welding anti-spatter agent is prepared from the following raw materials in parts by weight: 10 to 30 parts of film-forming agent, i.e. water-based polyurethane emulsion resin, 5 to 15 parts of cosolvent, i.e. isopropanol, 30 to 70 parts of deionized water, 2 to 10 parts of suspending agent, i.e. nanoscale silica powder, and 5 to 15 parts of thickening agent, i.e. polyacrylic acid emulsion. The invention further concretely discloses a preparation method of the water-based welding anti-spatter agent. When being used, the water-based weldinganti-spatter agent provided by the invention is directly sprayed, so that the working strength is small, and a uniform spraying effect is achieved; and the whole system is completely water-soluble, only water washing is needed during cleaning, and no residues left on a workpiece, so that time and labor are saved.

Description

technical field [0001] The invention belongs to the technical field of metal welding anti-splash chemical additives, and in particular relates to a water-based welding anti-splash agent and a preparation method thereof. Background technique [0002] With the development of industrial technology, people's demand for various metal equipment has increased greatly, including automobiles, shipbuilding, construction machinery and other industries have higher requirements for cheap and reliable metal connection technology. Metal connection has a long history, and today's technological development is changing with each passing day. The original metal forging welding technology has developed to advanced welding technologies such as arc welding and laser welding. When welding, it is necessary to use high temperature or high pressure to connect the solder and the base metal into a whole. The selection of process parameters, solder purity, atmosphere protection and welding direction wi...

Problems solved by technology

However, in the preparation process, all raw materials must be mixed and ground to a particle size of 45 microns in a sand mill to produce a finished product, which requires a lot of energy in the preparation of the finished product, and puts forward higher requirements for the production equipment ; It is mentioned in the article that the welding anti-spatter agent needs to be fully shaken and painted with a brush, which brings great inconvenience to the actual operation, and the efficiency is low. The phenomenon of uneven coating will seriously affect the actual use effect; the raw materials used in this invention contain calcium nitrate, and a large amount of use will cause environmental pollution
