Embodiment Construction

[0007] The embodiment of the invention discloses an antirust liquid. Embodiment described below will illustrate the present invention in detail:

[0008] The main components of the present invention are sodium benzoate, anhydrous carbonic acid, sodium nitrite, caustic soda, wheat straw and water. Its components are calculated by weight percentage: sodium benzoate accounts for 2%-5%, anhydrous carbonic acid accounts for 0.4%-0.7%, sodium nitrite accounts for 3%-8%, caustic soda accounts for 0.4%-0.6%, wheat straw Shan 4%- 7%, the rest is water.

[0009] The steps for preparing the product of the present invention: first, mix sodium benzoate, anhydrous carbonic acid, sodium nitrite, and wheat straw according to the weight percentage, then add an appropriate amount of water according to the weight percentage, and then add caustic soda according to the weight percentage, and When the liquid is mixed in each step, the mixed liquid is stirred to make it evenly mixed.

Abstract

The invention discloses antirust liquid, which belongs to the technical field of rust prevention. Traditional antirust liquid has the defect of bad antirust effect when being stored for a long time or transported after being treated. The antirust liquid disclosed by the invention comprises the following components by weight percent: 2-5 percent of sodium benzoate, 0.4-0.7 percent of anhydrous carbonic acid, 3-8 percent of sodium nitrite, 0.4-0.6 percent of caustic soda, 4-7 percent of wheat straw and the balance of water. After antirust treatment of the antirust liquid is carried out, products are not easy to rust in a longer storage or transportation time.

Description

technical field [0001] The invention relates to an antirust liquid, which belongs to the technical field of antirust. Background technique [0002] In the metal processing industry, anti-rust liquid is widely used for the purpose of anti-rust. However, although there are many types of anti-rust liquid products currently on the market, the anti-rust effect is not good. It is easy to rust within a short period of time and cannot achieve a good anti-rust effect. Contents of the invention [0003] The present invention aims at the deficiencies in the above-mentioned prior art and provides an antirust solution capable of making the products treated with antirust rust-proof for a long storage or transportation period. For this reason, the present invention adopts following technical scheme: [0004] An anti-rust solution, the composition of which comprises sodium benzoate, anhydrous carbonic acid, sodium nitrite, caustic soda, wheat straw and water, in percentage by weight: so...
