Problems solved by technology

In the past, no cleaning agents were developed for the special requirements for cleaning resin lenses before coating. Strong alkaline or methylene chloride solvent cleaning agents often limit the improvement of the pass rate of resin lens coatings.
The existing cleaning agents on the market cannot effectively remove various stubborn pollutants on the surface of the lens, and manual wiping is required to meet the requirements of the surface before coating, which greatly increases labor costs. damage to the health of the operator

Embodiment 1

[0058] Weigh each raw material according to the following mass fraction: 1% surfactin, 2% sophorolipid, 1% sodium hydroxide, 5% sodium carbonate, 3% sodium metasilicate, 2,3-butanediol furfural solvent 5%, N,N-diethylhydroxylamine 2%, and the balance is deionized water. The sophorolipid is a mixture obtained by the fermentation of Candida, which contains 50 wt% of acid type sophorolipid and 40 wt% of lactone type sophorolipid.

[0059] First, according to the mass content of each substance, add water into the reaction kettle, heat to 40°C, add sodium hydroxide, sodium carbonate, and sodium metasilicate in turn under stirring conditions, stir and dissolve for 2 hours, and then add surfactant peptides surfactin, Sophorolipids and N,N-diethylhydroxylamine were stirred and dissolved at 40°C for 1 hour, and finally 2,3-butanediol furfural solvent was added, and stirred and dissolved for 0.5 hours to obtain an environmentally friendly semi-aqueous cleaning combination thing.

Abstract

The invention discloses a semi-aqueous cleaning composition and a preparation method and application thereof. The composition comprises 5-20% of a permeation solvent, 1-5% of surface active peptide, 2-10% of sophorolipid, 1-5% of NaOH, 1-5% of sodium carbonate, 3-8% of sodium metasilicate, 2-15% of N, N-diethylhydroxylamine and water. The osmotic solvent is one or two of aldehyde condensation 2, 3-butanediol and ketone condensation 2, 3-butanediol, and the osmotic solvent is one or two of aldehyde condensation 2, 3-butanediol and ketone condensation 2, 3-butanediol; the mold cleaning agent for resin lens production, provided by the invention, has small damage to a mold, has a good removal effect on residual adhesives, resin monomers and resin solids at the edge of the mold, and effectively improves the qualified rate of resin lens production. Meanwhile, the cleaning agent provided by the invention has the characteristics of thorough oil removal, dust removal, surface residual fiber removal and the like, and the qualified rate of resin lens coating is effectively improved.

Description

technical field [0001] The invention belongs to the field of industrial cleaning and the field of optical resin material production and processing, and relates to an environmentally friendly semi-aqueous cleaning agent composition, in particular to a semi-aqueous bio-based solvent for cleaning glass molds and resin lenses before coating in the resin lens production process and surfactant compositions. Background technique [0002] In recent years, compared with inorganic glass lenses, polymer resin lenses have been favored by people because of their light weight, impact resistance, and convenient processing. From the perspective of the popularity of resin lenses, as early as 1988, optical resin lenses accounted for about 65% in the United States and about 55% in Japan. Recently, about 90 to 95% of people who wear glasses in Japan choose resin lenses. Therefore, in the long run, the popularization of polymer resin lenses will be the future development trend. [0003] The t...
