Problems solved by technology

However, the main problems of the antirust water in the prior art are: 1. The antirust water is easy to dry, and powdery precipitates are prone to appear on the valve surface, which affects valve detection and magnetic flaw detection; 2. The antirust water contains toxic sub- Nitrate, which cannot meet the requirements of environmental protection; 3. Insufficient anti-rust ability in hot and humid weather, which affects the anti-rust effect

Embodiment 1

[0013] The technical scheme of the present embodiment: a kind of antirust water between processes, which includes main antirust agent monoethanolamine benzoate, auxiliary antirust agent sodium silicate, and solvent glycerin and deionized water; wherein, the weight of each component The percentages are: monoethanolamine benzoate 1.0% to 2.0%, sodium silicate 0.4% to 1.0%, glycerol 2.0% to 4.0%, deionized water 93.0% to 96.6%; and each component is mixed and stirred to prepare .

[0014] The anti-rust water produced by the technical solution described in this embodiment is safe, non-toxic, environmentally friendly, and has good anti-rust performance. Among them, monoethanolamine benzoate is the main anti-rust agent, which can form an insoluble complex film on the surface of the air valve to play a role in anti-rust performance. Anti-rust effect, and sodium silicate is a colorless and transparent weakly alkaline viscous semi-fluid, which can form an amorphous silicone gel and iro...

Embodiment 2

[0016] In order to make the effect better, the present embodiment adopts the following technical scheme for the anti-rust between the processes after the semi-finishing of the valve: the weight percentages of the components of the anti-rust water are respectively: benzoic acid monoethanolamine 1.4% to 2%, silicon 0.6% to 1.0% sodium bicarbonate, 2.0% to 3.0% glycerol, and 94.0% to 96.0% deionized water.

[0017] The anti-rust water produced by the technical solution described in this embodiment is safe, non-toxic, environmentally friendly, and has good anti-rust performance. Among them, monoethanolamine benzoate is the main anti-rust agent, which can form an insoluble complex film on the surface of the air valve to play a role in anti-rust performance. Anti-rust effect, and sodium silicate is a colorless and transparent weakly alkaline viscous semi-fluid, which can form an amorphous silicone gel and iron hydroxide on the surface of the valve to form a protective film for anti-r...

Embodiment 3

[0019] Based on Example 2, in order to achieve the best anti-rust effect during valve semi-finishing, the present embodiment adopts the following technical scheme: the weight percentages of each component of the anti-rust water are respectively: benzoic acid monoethanolamine 1.7%, silicic acid Sodium 0.8%, glycerol 2.5%, deionized water 95.0%.

[0020] The anti-rust water produced by the technical solution described in this embodiment is safe, non-toxic, environmentally friendly, and has good anti-rust performance. Among them, monoethanolamine benzoate is the main anti-rust agent, which can form an insoluble complex film on the surface of the air valve to play a role in anti-rust performance. Anti-rust effect, and sodium silicate is a colorless and transparent weakly alkaline viscous semi-fluid, which can form an amorphous silicone gel and iron hydroxide on the surface of the valve to form a protective film for anti-rust effect. Sodium silicate and glycerine The combination of...

Abstract

The invention discloses inter-process antirust water which is prepared from the following components in percentage by weight: 1.0-2.0 percent of phenylformic acid monoethanol amine as a main antirust, 0.4-1.0 percent of sodium silicate as an auxiliary antirust, 2.0-4.0 percent of propanetriol solvent and 93.0-96.6 percent of deionized water. The invention has the advantages of safety, non-toxicity, environmental protection and favorable antirust performance, the phenylformic acid monoethanol amine used as the main antirust takes the antirust action by forming an insoluble complex membrane on a valve surface, the sodium silicate is water-white alkalescent viscous semiliquid and can form amorphous silicone gel to take the antirust action by forming a protection membrane together with iron hydroxide on the valve surface, the air drying of the antirust water can be greatly delayed by combining the sodium silicate and the propanetriol without forming powder precipitates, and the combination of the phenylformic acid monoethanol amine, the sodium silicate and the propanetriol also has favorable antirust performance in a damp-heat environment.

Description

technical field [0001] The invention relates to an antirust water, which belongs to the technical field of chemical solution products, in particular to an interprocess antirust water suitable for valves. Background technique [0002] The valve is a key part of the engine. Its processing process has the following requirements: 1. Rust spots are not allowed during the processing process, and anti-rust treatment between processes must be done; 2. The inspection requirements between processes are high, and crystallization and Powdery precipitates; 3. When the humidity is above 95% and the temperature is about 35°C, the anti-rust period between valve processes can reach more than 6 days; 4. The anti-rust water must be safe and non-toxic. However, the main problems of the antirust water in the prior art are: 1. The antirust water is easy to dry, and powdery precipitates are prone to appear on the valve surface, which affects valve detection and magnetic flaw detection; 2. The anti...
