Description

Technical Field

[0001] This utility model relates to the field of ship painting, and in particular to a gun washing thinner recovery device. Background Technology

[0002] In the field of marine painting, spray guns are often used for painting. Spray guns are mainly used for surface treatment, and the spraying material used is mainly anti-corrosion coating. Since anti-corrosion coating is a substance that is insoluble in water, the spray gun needs to be cleaned after painting to avoid the anti-corrosion coating residue from contaminating subsequent spraying. During cleaning, a cleaning agent is usually injected into the spray gun to carry away the residual anti-corrosion coating. However, in many cases, the waste liquid after cleaning the spray gun is directly discharged, which not only pollutes the environment, but also prevents the effective recycling of the solvent used to clean the spray gun.

[0003] Cleaning agents can be classified into three categories based on their solvents: water-based cleaning agents, semi-aqueous cleaning agents, and solvent-based cleaning agents. Water-based cleaning agents are formulated with surfactants such as sodium alkylbenzene sulfonate and sodium fatty alcohol sulfate, various additives such as sodium tripolyphosphate, and other auxiliary agents. When washing away dirt from object surfaces, these agents reduce the surface tension of the aqueous solution, improving the cleaning effect. Semi-aqueous cleaning agents are new types of cleaning agents synthesized from finely granulated, weakly alkaline adsorbents of various additives. They utilize natural interfacial active abrasive particles as raw materials, combined with various surfactants, bactericides, polishing agents, imported penetrants, and unique brightening factors, using environmentally friendly high-tech formulations. Solvent-based cleaning agents consist of hydrocarbon solvents, halogenated hydrocarbon solvents, alcohol solvents, ether solvents, ketone solvents, ester solvents, phenol solvents, and mixed solvents. Solvent-based cleaning agents refer to organic solvents that are insoluble in water. However, some common solvent-based cleaning agents, such as hydrocarbon solvents like isomeric hydrocarbons, cycloalkanes, or aromatic hydrocarbons, have low flash points and are classified as flammable and explosive hazardous chemicals. They are not only difficult to store, but also cannot be used at high temperatures, thus limiting their application range and posing significant safety hazards. In addition, they also have drawbacks such as poor cleaning effect. Summary of the Invention

Detailed Implementation

[0041] The present invention will now be further described in conjunction with the accompanying drawings and embodiments.

[0042] Example 1. A special gun cleaning thinner for ship painting, characterized in that the gun cleaning thinner contains the following substances in the following volume ratios: cyclopentyl methyl ether 40-45%, cyclohexanediol monoethylene glycol monomethyl ether 2-3%, isocyanurate 1-2%, ethylene glycol monomethyl ether 0.5-2%, acetate 1-1.5%, flame retardant 0.5-1%, deodorizer 0.5-1%, dimethyl glutarate 1-1.5%, n-butanol 8-10%, cyclohexanone 6-8%, and the remainder being solvent oil.

[0043] Specifically, the gun cleaning thinner contains the following substances in the following volume ratios: 40% cyclopentyl methyl ether, 2% cyclohexanediol monoethylene glycol monomethyl ether, 1% isocyanurate, 0.5% ethylene glycol monomethyl ether, 1% acetate, 0.5% flame retardant, 0.5% deodorizer, 1% dimethyl glutarate, 8% n-butanol, 6% cyclohexanone, and the remainder is solvent oil.

[0044] Cyclopentyl methyl ether is a novel, environmentally friendly, high-performance hydrophobic ether solvent that can replace ether solvents such as tetrahydrofuran, methyltetrahydrofuran, methyl tert-butyl ether, and dioxane. As a reaction solvent, it can be used in Grignard reactions, coupling reactions, coupling amination reactions, metal reduction reactions, Lewis acid reactions, and other reactions. Cyclopentyl methyl ether exhibits low toxicity, high hydrophobicity, low latent heat of vaporization, easy recovery, and stable properties, making it excellent for environmental protection. Isocyanurate can release active chlorine, exhibiting strong oxidizing properties. Ethylene glycol monomethyl ether, a colorless and transparent liquid at room temperature, can mix evenly with other components in cleaning agents to form an emulsion, enhancing cleaning ability. Ethylene glycol monomethyl ether also has a certain antistatic effect in cleaning agents, reducing interference and adverse effects caused by static electricity. Ethylene glycol monomethyl ether can dissolve organic substances such as grease, glue, and resin in cleaning agents. The use of dimethyl glutarate in cleaning agents is not explicitly mentioned, but its physical and chemical properties may make it effective in certain specific situations. Dimethyl glutarate is a stable ester organic compound, a colorless, clear liquid under normal conditions, flammable, with a boiling point of 214℃ (0.9 MPa), and highly soluble in ethers and alcohols. It can dissolve a variety of compounds and is widely used in coatings, cleaning agents, dyes, and resins. n-Butanol also serves as a reaction intermediate, participating in numerous chemical reactions and aiding in the synthesis of esters, ethers, and other organic compounds. Cyclohexanone is a high-boiling-point solvent. Acetates provide excellent volatility and film-forming properties. Cyclohexanediol monoethylene glycol monomethyl ether is a colorless, transparent liquid with a distinctive ether odor. Its flash point is 76℃. Furthermore, its surface tension is 31.24. Notably, its relative evaporation rate is only 0.053, significantly lower than that of butyl acetate. Simultaneously, its volume resistivity reaches 1.0 × 10⁻⁶. 8 With a refractive index of 1.4587 and a Ω·m, this solvent has a unique chemical structure containing two highly dissolving groups: an ether bond and a hydroxyl group. This gives it lipophilic properties, enabling it to dissolve hydrophobic compounds. Therefore, cyclohexanediol monoethylene glycol monomethyl ether is miscible with water and many other compounds such as alcohols, ethers, ketones, and esters, earning it the reputation of a "universal" solvent. Marine coatings often contain anti-corrosion substances such as epoxy resins and asphalt. These substances tend to clump together into small particles on the spray gun; using the above combination can quickly remove these substances.

[0045] Flame retardants are functional additives that impart flame-retardant properties to flammable polymers, primarily designed for flame retardancy in polymer materials. There are various types of flame retardants, categorized by application method into additive flame retardants and reactive flame retardants. Additive flame retardants are added to polymers through mechanical mixing to impart flame retardancy. Currently, additive flame retardants mainly include organic and inorganic flame retardants, halogenated flame retardants (organochlorides and organic bromides), and non-halogenated flame retardants. Organic flame retardants are represented by bromine-based, phosphorus-nitrogen-based, nitrogen-based, and red phosphorus and its compounds, while inorganic flame retardants mainly include antimony trioxide, magnesium hydroxide, aluminum hydroxide, and silicon-based flame retardant systems. Reactive flame retardants participate in the polymerization reaction as monomers, thus imbuing the polymer itself with flame-retardant components. Their advantage is minimal impact on the performance of the polymer material and long-lasting flame retardancy. The flame retardant is selected from at least one of phosphorus-based, nitrogen-based, and bromine-based flame retardants. Specifically, in this embodiment, the phosphorus-based flame retardant is FR-320.

[0046] Its beneficial effects are as follows: Anti-corrosion coatings used in ship painting often contain anti-corrosion components such as epoxy resin and coal tar pitch. Using this ship painting-specific gun cleaning thinner can effectively dissolve these components. Furthermore, this gun cleaning thinner has the characteristics of a high flash point, non-flammability, and odorless environmental friendliness. Its closed-cup flash point is 68 degrees Celsius, meeting the requirements for non-hazardous chemical identification in the "Regulations on the Safety Management of Hazardous Chemicals," classifying it as a non-hazardous chemical. Recycling this gun cleaning thinner can save costs and reduce VOC emissions. Its chemical composition does not contain halogenated solvents such as dichloromethane or benzene solvents, is non-toxic to humans, and does not damage or pollute the atmospheric ozone layer.
