Problems solved by technology

In the process of use, the demand is huge, and the cost is high, and heavy metal agents are added, causing greater environmental pressure and safety hazards
[0005] In addition, there are some borate and carboxylate water-based anti-rust agents on the market. Because of their short anti-rust time, they often only have a short-term anti-rust effect.
[0006] Others, such as products that use sodium nitrite as a water-based antirust agent, although the antirust effect is relatively good, but sodium nitrite is carcinogenic and will pose serious health risks to personnel in various links of production, manufacturing and use. At present, many The country has banned the use of

Abstract

The invention provides an environment-friendly water-based antirust agent. The antirust agent is characterized by being prepared from the following raw materials according to weight percentage: 1-99% of urea phosphate, 0-5% of surfactant, 0-2% of sodium hydroxide or potassium hydroxide and the balance of water. The environment-friendly water-based antirust agent is prepared by sequentially adding the raw materials into water. The environment-friendly water-based antirust agent has excellent effects, can be used as a long-term antirust agent, can also be used as an excellent interprocess antirust agent after being added with water, and has the longest antirust time of three years, and furthermore, the antirust agent has the effects of energy conservation, emission reduction and environment protection.

Description

technical field [0001] The invention belongs to the technical field of metal antirust, and in particular relates to an environment-friendly water-based antirust agent and a preparation method thereof. Background technique [0002] Anti-rust oil is generally used for medium and long-term anti-rust of traditional metals, but anti-rust oil generally contains heavy metal ions such as barium and chromium. As we all know, heavy metal compounds cannot be excreted after entering the organism due to their insoluble characteristics, which will cause chronic poisoning . Therefore, some countries in Europe and the United States have imposed strict restrictions on its use. Although my country has not explicitly imposed relevant bans and restrictions on its use, from the perspective of environmental protection, health and safety, the restriction and non-use of such substances is an inevitable trend. [0003] At the same time, due to the current depletion of oil resources and rising oil ...
