Problems solved by technology

For cleaning objects: Halogenated hydrocarbon solvents are easy to acidify, corrode equipment and electronic circuits, and affect electrical performance. Moreover, halogenated hydrocarbons have poor compatibility and have swelling and corrosion effects on most rubbers and plastics.
The use of these ODS products will be banned one after another in recent years. The market needs new environmentally friendly alternatives. However, the water-based cleaning solutions developed in recent years often use strong alkali or phosphides such as potassium pyrophosphate and sodium tripolyphosphate in the formula. And some non-environmentally friendly chelating agents such as oxalic acid tetraacetate sodium salt (EDTA sodium salt) and nitrogen compounds (such as NTA) etc., EDTA sodium salt has been proved to be very difficult to degrade, and NTA etc. are suspected of being very harmful. Strong carcinogenicity, not only pollutes the environment, but also causes immeasurable harm to the human body

Abstract

The invention discloses a water-based optical lens cleaning agent composition, which comprises the following raw materials in parts by weight: 5-10 parts of organic base, 3-5 parts of inorganic base, 3-5 parts of environment-friendly chelating agent, 10-15 parts of dispersing agent, 15-20 parts of penetrating agent and 40-60 parts of de-ionized water. The water-based optical lens cleaning agent composition has the advantages that 1, the composition is an ODS (Ozone Depleting Substance) cleaning liquid substitute in the optical electronic cleaning industry, 2, the composition is a highly concentrated product and is only required to be diluted in water according to a proportion of 3-5 percent to have an excellent cleaning effect, 3, the composition is made of environment-friendly raw materials, has oral toxicity, can be contacted with skin, has extremely low inhalation toxicity and is safe to human bodies and easy to biodegrade, 4, the composition is safe to a cleaned object, does not corrode a lens, has excellent compatibility, meanwhile has excellent compatibility with most of rubber and plastic, does not swell or corrode and the like, and 5, the composition has strong cleaning power, is uniform in filming on the lens after cleaning, does not produce fog or spots and has no phenomenon of bubbling, the filming yield is greatly improved, and the production efficiency is increased.

Description

Technical field: [0001] The invention relates to a cleaning agent composition, in particular to a water-based optical lens cleaning agent composition. Background technique: [0002] In the optical electronics industry, white spots, residual grinding powder, adhesives, cutting oil, dust, and fingerprints, dust, and oil stains left before and after coating of optical lenses produced by cutting and grinding are traditionally used. Freon, trichloroethane, The cleaning of traditional halogenated hydrocarbon solvents such as trichloroethylene has the advantages of strong cleaning ability, no flash point, fast drying speed and distillable recovery, etc., and is widely used. However, this type of cleaning liquid has many disadvantages. The human body, the environment and the objects to be cleaned are all very harmful. To the human body: the above halogenated hydrocarbon solvents are very toxic. Long-term exposure to or inhalation of vapors by the human body can easily cause liver, kidne...
