Problems solved by technology

In terms of technology, incomplete degreasing will directly affect the operation of the next process, and may pollute the subsequent production line; in terms of coating quality, incomplete degreasing will reduce the adhesion of the coating film, and will also affect the coating quality. other properties
Frequently encountered in industrial production, such as uneven blackening at room temperature, inconsistent color, partial blackening, electroless plating leakage, poor bonding force, pinholes and other problems are directly related to the incomplete degreasing of the pre-treatment. relation

Abstract

The invention discloses a metal oil removal agent and a preparation method thereof and aims to provide an oil removal agent which can completely remove oil dirt on the metal surface at normal temperature and is environmentally friendly in formula. According to the technical key points, every liter of oil removal agent comprises the following components: 120-200g of oxalic acid, 100-150g of carbonate, 10-30g of fatty alcohol-polyoxyethylene ether, 2-5g of alkylphenol polyoxyethylene, 5-15g of thiourea, 20-40g of ethylene diamine tetraacetic acid and the balance of water. The method for preparing the metal oil removal agent comprises the following steps: (1) weighing each component; and (2) adding the components weighed in the step (1) into a flask, adding water to 1L, stirring at the temperature of 50-80 DEG C for 5-10 minutes, and obtaining the metal oil removal agent. The invention belongs to the technical field of metal cleaning.

Description

technical field [0001] The invention relates to a metal degreasing agent, in particular to a steel or copper or aluminum or stainless steel degreasing agent, belonging to the technical field of metal cleaning. Background technique [0002] When metal is deformed or cut, the surface of the metal product is often stained with some oil. These oil stains mainly come from the following points: 1. Anti-corrosion protection of base materials; 2. Oil stains introduced by mechanical or die-casting processing; 3. Anti-rust treatment between processes; 4. Introduction of other processes before electroplating; 5. Metal storage , handling and processing, the surface is inevitably polluted by some dirt from the outside world. These pollutants include engine oil, anti-rust oil, cutting oil, grinding paste, animal and vegetable oil, dust and other pollution introduced during operation. [0003] These oil stains seriously affect the operation of subsequent processes and the quality of prod...
