Environment-friendly degumming agent and producing process thereof

Abstract

The invention relates to an environment-friendly degumming agent and a producing process thereof. The environment-friendly degumming agent comprises the following materials by mass percent: 95-99% of water, 0.1-0.5% of active agent and 0.5-4.9% of organic acid. The process comprises the steps of adding water into a mixing container, filling nitrogen into the mixing container for bubbling, adding organic acid and active agent, mixing uniformly and filtering with a precision filter to obtain the environment-friendly degumming agent. The environment-friendly degumming agent reacts with shellac and ester gum to become water soluble matters, and the shellac and ester gum are rapidly dissolved in water to achieve the effect of separating glass substrates, so that the degumming agent is unlikely to volatilize, pollution-free, convenient to process, rapid in effect and complete in reaction and has no substrate residues.

Description

technical field [0001] The invention relates to an environment-friendly degumming agent and a production process thereof. Background technique [0002] In the fields of optics, LED, and crystal oscillators, the mixture of shellac and rosin glue is often used to bond optical glass and crystal. This product can peel off the bonded glass again, and clean and remove the shellac on the surface of optical glass and crystal. and rosin gum. The existing degumming agent used for cleaning is generally made of n-butanol, absolute ethanol, and acetone. , a good solvent for rosin glue, so when choosing to separate the above two products as the glass substrate of the adhesive, first think of dissolving the colloid to achieve the separation effect; but although the above solvent can dissolve the colloid, the dissolution time is long and the separation is difficult. It is slow and difficult to clean the glass surface thoroughly, and the effect is slow. In addition, it is volatile and caus...

The existing degumming agent used for cleaning is generally made of n-butanol, absolute ethanol, and acetone. , a good solvent for rosin glue, so when choosing to separate the above two products as the glass substrate of the adhesive, first think of dissolving the colloid to achieve the separation effect; but although the above solvent can dissolve the colloid, the dissolution time is long and the separation is difficult. It is slow and not easy to clean the glass surface thoroughly, and the effect is slow. In addition, it is volatile and causes environmental pollution. At the same time, the residual liquid after cleaning is hazardous waste, and incineration treatment may easily cause dioxin pollution.
