A kind of canned spray type welding anti-splash agent and preparation method thereof

Abstract

The invention discloses a canned spray type welding anti-splashing agent and a preparation method thereof and belongs to the technical field of fine chemical engineering. According to the technical scheme, the agent is characterized by being prepared from raw materials in parts by weight as follows: 40-60 parts of petroleum ether, 10-20 parts of ethyl acetate, 20-40 parts of isopropanol or / and ethanol with the volume fraction being 95%, 1-3 parts of alcohol-soluble polyamide, 2-4 parts of rosin glycerin ester or / and terpene phenolic resin, 1-2 parts of C5 petroleum resin, 1-2 parts of fumed silica of 4,000-5,000 meshes, 2-4 parts of nano-aluminium oxide or / and zinc chloride of 100-200 nm and 2-3 parts of rutile powder of 2,000-3,000 meshes. The invention further discloses the preparation method of the agent. The agent is convenient to carry, sanitary and rapid to spray and capable of effectively reducing the labor amount of welding workers and improving the welding efficiency.

Description

technical field [0001] The invention belongs to the technical field of fine chemicals, and in particular relates to a canned spray-type welding anti-splash agent and a preparation method thereof. Background technique [0002] When metal workpieces are welded, the electrode and the base metal are partially melted under the arc high temperature condition generated by the current, and the liquid metal is thrown at high speed due to the sharp high temperature explosion to form a scorching, bright and dazzling weld. Weld spatter is mainly composed of electrode metal. When the current is too high, the spatter of the motherboard material will also increase. The formation of welding spatter is extremely unfavorable to welding work: firstly, the hot welding slag can easily burn the skin, and the smoke and dust caused by tiny particles of flying debris, especially PM2. , health hazard; secondly, the spattered welding slag adheres to the hot welding surface and solidifies, polluting t...

The formation of welding spatter is extremely unfavorable to welding work: firstly, the hot welding slag can easily burn the skin, and the smoke and dust caused by tiny particles of flying debris, especially PM2. , health hazard; secondly, the spattered welding slag adheres to the hot welding surface and solidifies, polluting the weld seam, resulting in uneven or rough welding, and cleaning up the welding slag is not only time-consuming and laborious, but also easily damages the solder; finally , the spattered welding slag causes the waste of the welding rod, and the metal splash at the masterbatch is also a kind of damage to the components

[0003] In order to reduce welding slag, anti-spatter agents will be used in welding operations. The simplest anti-spatter agents are compounded with non-metallic powders such as rutile powder, calcium nitrate powder, and montmorillonite powder. They are sprinkled on the welding place when used, but This kind of anti-splash agent has extremely poor adhesion, and the amount of use is large and wasteful. When non-flat welding, it is almost impossible to adhere to the welding place and cannot be used. Even for general flat welding, when it is used, the particles fall into the welding place and seriously affect the welding. Quality, fly into the air to form flying dust and cause serious pollution; water-based anti-scattering agent requires a long drying time after painting, and the nitrogen oxide gas generated after the nitrate anti-rust agent in the compound system is burned will pollute the local air. Harmful to the health of workers; oil-based anti-splash agent, the oil-based component is likely to produce a lot of welding fumes when used, and the residual oil will pollute the workpiece after use, and the wiping process is time-consuming and laborious

Because the anti-splash agent is a small product in the fine chemical industry, for a long time, the quality of the products launched by the chemical manufacturing industry is not high, and the attention of the technology research and development industry is not high.
