Embodiment 1

[0035] Mix 18 parts of ethylene glycol diacetate (EGDA), 73 parts of diethylene glycol butyl ether, and 9 parts of toluene dimethyl phosphate under normal temperature and pressure to obtain a non-flammable and safe solvent.

[0036] Then take part of the above-mentioned non-flammable and safe solvent and mix it with a commercially available alkyd protective coating at a volume ratio of 1:9 until it can be painted. The properties of the paint film are recorded in Table 1.

Embodiment 2

[0038] Mix 18 parts of EGDA, 70 parts of diethylene glycol butyl ether, and 12 parts of phenyl phosphate dichloride evenly under normal temperature and pressure to obtain a non-flammable and safe solvent.

[0039] Then take part of the above-mentioned non-flammable and safe solvent and mix it with a commercially available alkyd protective coating at a volume ratio of 1:9 until it can be painted. The properties of the paint film are recorded in Table 1.

Embodiment 3

[0041] Mix 43 parts of diethylene glycol butyl ether, 45 parts of diethylene glycol dimethyl ether, and 12 parts of tris(α-chloroethyl)phosphate evenly under normal temperature and pressure to obtain a non-flammable and safe solvent.

[0042] Then take part of the above-mentioned non-flammable and safe solvent and mix it with a commercially available alkyd protective coating at a volume ratio of 1:9 until it can be painted. The properties of the paint film are recorded in Table 1.

Abstract

The invention provides a non-combustible safe solvent and application thereof, which belong to the technical field of coatings. The non-combustible safe solvent disclosed by the invention is prepared from 80 to 100 parts of a high-flash-point solvent and 5 to 15 parts of a phosphorus-containing flame retardant. The volatilization speed of the used high-flash-point solvent is lower than that of conventional solvents such as xylene and butyl acetate, after the low-volatility flame retardant is added, the volatilization speed is further reduced, and the effect of moderate volatilization speed is achieved; in the coating process after the paint is mixed with the diluent, the phenomenon that a paint film is softened due to the fact that a small amount of solvent is left due to the low volatilization speed of the diluent is avoided, and the leveling property and gloss of the paint film can be improved.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a nonflammable and safe solvent and its application. Background technique [0002] At present, the main solvents used in the coating industry, including xylene, methyl acetate, butyl acetate, etc., are extremely flammable liquids. In order to solve the safety hazards brought by these substances, additional investment is required in transportation and storage, including special transport vehicles, special storage warehouses, etc. This greatly increases the cost of using these solvents. One way to reduce these additional expenses is to use safe solvents. Contents of the invention [0003] The purpose of the present invention is to provide a safe, environment-friendly and non-flammable solvent, specifically a non-flammable and safe solvent and its application. [0004] In order to achieve the above-mentioned purpose of the invention, the present invention provides the followin...
