Normal-temperature degreasant and preparation method thereof

Abstract

The invention relates to a normal-temperature degreasant and a preparation method thereof, and belongs to the technical field of metal surface treatment. According to the normal-temperature degreasant, normal-temperature degreasing can be realized even in winter, the degreasing time is short, the detergent washing degree is high and organic phosphorus is not contained. The normal-temperature degreasant comprises the following materials in parts by weight: 7-9 parts of trisodium phosphate, 1.5-2 parts of sodium tripolyphosphate, 70-110 parts of sodium metasilicate, 35-40 parts of sodium carbonate, 2-4 parts of sodium citrate, 4-8 parts of sodium lignin sulfonate, 20-42 parts of anhydrous sodium sulphate, 20-30 parts of caustic soda flakes, 30-32 parts of water, 26-30 parts of polyether, 100-150 parts of alkylphenol ethoxylates and 10-25 parts of fatty alcohol-polyoxyethylene ether. The normal-temperature degreasant is applied to the technical field of metal surface scrubbing.

Description

technical field [0001] The invention discloses a normal temperature degreasing agent and a preparation method thereof, belonging to the technical field of metal surface treatment. Background technique [0002] Since the civilization era of slash-and-burn farming, the use of tools and dependence on metals have never stopped. With the rapid development of modern industry, the output of steel has become an important symbol to measure the comprehensive strength of a country. The continuous doubling of steel production and the fact that a large amount of steel is corroded has plagued generations of producers and users. Because of this, many colleges, universities, scientific researchers and engineering technicians have invested in the battle of steel anti-corrosion, degreasing, pickling, phosphating, coating, electroplating and other anti-corrosion processes and technologies are emerging. [0003] Human beings cannot avoid dealing with oil for a day. We need animal oil and veg...

Problems solved by technology

At present, there are many kinds of normal temperature degreasing agents on the market, but there are generally defects such as the impact of phosphorus-rich formulas on the environment, high degreasing temperature, long degreasing time, and poor degreasing cleanliness.

[0008] The main components of existing degreasing agents are compounds of phosphate, caustic soda, soda ash, etc., which can meet the requirements of small and medium-sized enterprises in summer. It is difficult to use it normally, and it is even more difficult to produce in cold areas such as Shanhaiguan, Gansu, and Xinjiang. It will be difficult to continue to use it if it is not heated to 20-30°C in winter

A large number of practices have proved that any single degreasing method and raw material has defects of one kind or another;

[0009] Many small and medium-sized enterprises generally have difficult heating conditions, do not have the steam heating pipelines of large enterprises, and generally have poor production batches and overall planning. Environment, or stop production in winter! In order to solve the desire to continue production in winter while saving energy and reducing emissions, the inventor finally successfully launched a low-temperature degreasing agent with strong adaptability after years of exploration, filling the gap in this field
