Embodiment 1
[0030] Example 1 Prepare about 1000 kg of protective agent.
[0031] Carry out the proportioning of each component according to the following ratio: the organic corrosion inhibitor is 1 kilogram of triazole, oleoyl imidazoline (weight ratio is 1: 3), and film-forming substance is ozokerite and insect wax (weight ratio is 1 : 2) 30 kilograms, surfactant OP10 is 0.5 kilograms, surplus is 968.5 kilograms of hydrocarbon solvents.
[0032] The preparation process of this embodiment is:
[0033] 1. Pour the organic corrosion inhibitor, film-forming substance, surfactant and 1 / 4 of the above-mentioned solvent into the reactor;
[0034] 2. Heating to 40-42°C, constant temperature for 30-32min;
[0035] 3. After cooling to room temperature, add the remaining solvent and continue stirring;
[0036] 4. After stirring evenly, fill.
Embodiment 2
[0037] Example 2 Prepare about 1000 kg of protective agent.
[0038] Carry out the proportioning of each component according to the following ratio: the organic corrosion inhibitor is 20 kilograms of benzotriazoles, the film-forming substance is 5 kilograms of insect wax, the surfactant OP10 is 3 kilograms, and the balance is 972 kilograms of chain hydrocarbon solvents .
[0039] The preparation process of this embodiment is:
[0040] 1. Pour the organic corrosion inhibitor, film-forming substance, surfactant and 1 / 2 of the solvent in the above ratio into the reaction kettle;
[0041] 2. Heating to 48-50°C, constant temperature for 38-40min;
[0042]3. After cooling to room temperature, add the remaining solvent and continue stirring;
[0043] 4. After stirring evenly, fill.

Abstract
The invention relates to a surface protectant mainly used for metal components of electrical appliances and a preparation method thereof. The surface protectant is prepared by 0.1-2% of organic inhibitor, 0.5-3% of film-forming substance, 0.05-0.3% of surfactant and solvent being balance through mixing and heating. The invention adopts an organic solvent as a solvent to prepare the protectant, thus having good dispersive capacity, infiltration capacity and sealing capacity; about 1mum semi-solid hydrophobic film is formed on the metal surface to block micropores on the metal surface, thus preventing harmful gases and other media from eroding the metal and improving the salt fog resistance, moisture resistance and mucedine resistance of the metal as well as the capability of the metal in resisting various severe environments; the film has good adhesive force, thus obviously improving the lubricating property and wearing resistance with no effect on the conductivity. The protectant can be widely applied to the sealing treatment of nickel coating of electronic components or printed circuit boards, aluminum alloy conduction and oxidation, gold plating, stainless steel, copper surface and zinc coating. The surface protectant is simple in production technology, convenient in use and low in cost.
Description
technical field [0001] The invention relates to a metal surface protective agent, in particular to a surface protective agent mainly used for electrical components or printed circuit boards and a preparation method thereof. Background technique [0002] The anti-corrosion problem of metal is a worldwide problem. After the metal is corroded, it will change in appearance, color, electrical properties and mechanical properties, causing equipment damage, pipeline leakage, product pollution, combustion or explosion, etc. Accidents and serious waste of resources and energy have caused huge losses to the national economy. According to estimates, the annual economic losses caused by metal corrosion in developed countries in the world account for about 3.5% to 4.2% of their gross national product, which exceeds the sum of the annual losses of various catastrophes (fires, wind disasters and earthquakes, etc.). For this reason, various countries have invested considerable manpower and...
