Description

Technical Field

[0001] The present invention particularly relates to a chemical milling protective glue. Background Art

[0002] Traditional milling protective glue uses highly toxic toluene, xylene and highly toxic and carcinogenic tetrachloroethylene as solvents for glue. These traditional ingredients have the following problems: Toluene: Toluene is an organic solvent commonly used in products such as paints, coatings, and glues. Its harmful effects on the human body include both acute and chronic effects. For example, short-term exposure may cause irritation to the eyes and respiratory tract, while long-term exposure may affect the nervous system and even pose a risk of cancer. Regarding environmentally friendly materials, toluene, as a volatile organic compound (VOC), is released into the air during manufacturing and use, leading to VOC pollution and potentially forming ozone and PM2.5. Toluene can take a long time to degrade in the environment, especially under hypoxic conditions, and may accumulate in soil or water, impacting the ecosystem.

[0003] Xylene: Xylene is an aromatic hydrocarbon with two methyl groups on the benzene ring. Three common isomers (o-, m-, and p-xylene) are used in mixed form in industry. As a typical volatile organic compound (VOC), it is widely used in paints, coatings, adhesives, and printing inks, but it poses significant risks to humans and the environment.

[0004] Tetrachloroethylene: Tetrachloroethylene, also known as perchloroethylene (PCE), is a chlorinated solvent widely used in dry cleaning, metal degreasing, and electronics cleaning. Despite its strong cleaning properties, it poses significant risks to human health and the environment, and is increasingly subject to global regulatory restrictions. The International Agency for Research on Cancer (IARC) classifies it as a Group 2A carcinogen (probably carcinogenic to humans), primarily based on animal liver and kidney cancer studies.

[0005] In summary, the existing milling protection glue has problems such as being environmentally unfriendly and highly toxic. Therefore, the present application proposes a chemical milling protection glue to solve the above problems. Summary of the Invention

[0006] The object of the present invention is to provide a chemical milling protective adhesive to address the deficiencies in the prior art, and the chemical milling protective adhesive can well solve the above-mentioned problems.

[0007] In order to achieve the above requirements, the technical solution adopted by the present invention is: to provide a chemical milling protective glue, which includes a polymer resin material and methylcyclohexane or dichloropropane.

[0008] Preferably, the chemically modified protective colloid contains both methylcyclohexane and dichloropropane.

[0009] Preferably, methylcyclohexane and dichloropropane are mixed with the polymer resin material in any proportion.

[0010] The advantages of this chemical milling protective glue are as follows: Chemical milling protective adhesive can be widely used in the local chemical milling of aluminum plates in aerospace. It has the characteristics of high milling accuracy, low corrosion resistance, easy glue, low toxicity, etc., filling the market gap of similar products in China. It is a perfect alternative material to traditional conventional imported chemical milling protective adhesive. DETAILED DESCRIPTION
