Embodiment 1~4

[0046] Table 1 Composition content and comparative examples of Examples 1-4

[0047]

[0048] Carry out salt spray test to each embodiment and comparative example respectively, the result is as follows. The salt spray test is carried out in accordance with SH / T 0081.

Embodiment 1

[0050] According to the ingredients and proportions of Example 1 in Table 1, heat the wax and base oil to 80-100°C to become A, and heat the anti-rust agent and neutralizer to 80-100°C to become B, and then stir A and B to melt Form oil phase; add emulsifier into water and heat to 80-95°C to form water phase; add water phase to oil phase under stirring, keep warm, stir, neutralize, and cool to form oil-in-water type with high oil phase content Anti-rust lotion.

[0051] The antirust emulsion has the following properties:

[0052] Emulsion type: oil in water

[0053] System solid content: 67.5%;

[0054] Neutral salt spray test results: 0 level after 240 hours; see figure 1 Corrosion comparison chart of the test piece before and after the experiment. in, figure 1 The left is before the salt spray test, and the right is 240 hours after the salt spray test.

Embodiment 2

[0056] According to the composition and ratio of Example 2 in Table 1, the wax and base oil are heated to 80-100°C to become A, and the anti-rust agent and neutralizing agent are heated to 80-100°C to become B, and then A and B are stirred and melted to form Oil phase; add the emulsifier to water and heat to 80-95°C to form a water phase; add the water phase to the oil phase under stirring, keep warm, stir, neutralize, and cool to form an oil-in-water type anti-corrosion oil with high oil phase content. rust lotion.

[0057] The antirust emulsion has the following properties:

[0058] Emulsion type: oil in water

[0059] System solid content: 61%;

[0060] Neutral salt spray test results: after 240 hours, it can be judged as level 0; see image 3 Corrosion comparison chart of the test piece before and after the experiment. in, figure 2 The left is before the salt spray test, and the right is 240 hours after the salt spray test.

Abstract

The invention provides high oil phase content oil-in-water type anti-rusting emulsion. The high oil phase content oil-in-water type anti-rusting emulsion is composed of, by weight, 5-30% of wax, 0-40% of base oil, 1-20% of anti-rusting agents, 0.1-2% of neutralizers, 1-10% of emulsifying agents and water. The proportion of the oil phase in the emulsion can reach 50-78 wt%. A continuous hydrophobic oil film can be formed on the surface of a metal material, the adhesive force is high, and the anti-rusting property is good. The emulsion has excellent spreading permeability, film-forming property, water displacement property, anti-rusting property and construction performance, and a quite good long-term protection effect is achieved for the metal material.

Description

technical field [0001] The invention relates to anticorrosion and antirust materials, in particular to an oil-in-water antirust emulsion with high oil phase content. Background technique [0002] Pure oil or pure oil composition has existed in the field of metal anti-corrosion for a long time. Such compositions generally contain volatile organic solvents, which are prone to fire, environmental pollution, and human health during construction and storage. . Therefore, it has become a trend in recent years to replace oily rust inhibitors with water-based rust inhibitors. [0003] Water-based antirust emulsion has the advantages of stable storage, low odor, convenient construction, good permeability, and no VOC emission problems. However, the antirust emulsion prepared by high temperature emulsification with base oil, wax, antirust agent, corrosion inhibitor, emulsifier, etc. generally forms a soft film type protective film, which is easily washed off by hot water or detergent...
