Embodiment 1

[0023] A surface coating agent is composed of the following components according to mass percentage: sodium silicate (NaSiO 3 · nSiO2 3 , n=2) 3%, alcohol 10%, water 30%, and the rest is nitrogen.

[0024] The preparation method of above-mentioned surface coating agent is as follows:

[0025] (1) According to the above formula, add water first, and then add sodium silicate;

[0026] (2) Add alcohol after the sodium silicate is dissolved.

[0027] (3) Filter out the impurities in the mixture.

[0028] (4) Add the above mixture into a pressure tank and add compressed nitrogen to prepare the surface coating agent.

[0029] Note that during the preparation process, it cannot be exposed to air.

[0030] When the above-mentioned surface coating agent is used, it only needs to be placed in a bottle and evenly sprayed on the surface of the object.

Embodiment 2

[0032] A surface coating agent is composed of the following components according to mass percentage: sodium silicate (NaSiO 3 · nSiO2 3 , n=3) 10%, alcohol 20%, water 50%, and the rest is nitrogen.

[0033] Among the above components, the functions of each component are as follows: sodium silicate is the main coating material, alcohol mainly helps the solvent volatilize, water is the solvent and reactant, and nitrogen is the propellant, which helps to spray evenly during coating.

[0034] The preparation method of above-mentioned surface coating agent is as follows:

[0035] (1) According to the above formula, add water first, and then add sodium silicate;

[0036] (2) Add alcohol after the sodium silicate is dissolved.

[0037] (3) Filter out the impurities in the mixture.

[0038] (4) Add the above mixture into a pressure tank and add compressed nitrogen to prepare the surface coating agent.

Embodiment 3

[0042] A surface coating agent is composed of the following components according to mass percentage: sodium silicate (NaSiO 3 · nSiO2 3 , n=3.4) 6%, alcohol 15%, water 70%, and the rest is nitrogen.

[0043] The preparation method of above-mentioned surface coating agent is as follows:

[0044] (1) According to the above formula, add water first, and then add sodium silicate;

[0045] (2) Add alcohol after the sodium silicate is dissolved.

[0046] (3) Filter out the impurities in the mixture.

[0047] (4) Add the above mixture into a pressure tank and add compressed nitrogen to prepare the surface coating agent.

[0048] Note that during the preparation process, it cannot be exposed to air.

[0049] When the above-mentioned surface coating agent is used, it only needs to be placed in a bottle and evenly sprayed on the surface of the object.

Abstract

The invention relates to a surface coating agent and belongs to the technical field of surface coating. The surface coating agent is composed of the following components by weight percent: 3-10% of sodium silicate (NaSiO3.nSiO3, n=2-4), 10-30% of alcohol, 50-80% of water and the balance of nitrogen. The surface coating agent can be used for overcoming the defect that the existing coating agent has certain toxic ingredients and is inconvenient to use in occasions in contact with a human body and the defects that the coating manner is quite complex and slightly inconvenient to use. The surface coating agent provided by the invention contains no toxic ingredient and is produced from sodium silicate, water and alcohol and formed by means of compression of nitrogen; in use, the surface coating agent only needs to be evenly sprayed on the surface of an object; the surface coating agent is wide in application range, convenient to use, low in cost and suitable for various occasions.

Description

technical field [0001] The invention belongs to the technical field of surface coating agents, and more specifically relates to a surface coating agent. Background technique [0002] Surface coatings are widely used in the fields of automobiles, textiles, metal surface treatment, etc., and are an inseparable part of people's lives. However, these coating agents generally have complicated processes or toxic components, which limit their use. [0003] For example, automobiles are one of the modern means of transportation, and the use of automobiles is becoming more and more common. The outer shell of the car is usually made of thin steel plate, and a layer of paint is sprayed on the outer shell surface. Because the car is driven and parked outside for a long time, it is inevitable to be exposed to the sun, rain, wind and dust. Therefore, it is necessary to coat the outer shell of the car It is very necessary to prevent the external harmful substances from corroding the car sh...
