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
What the present invention relates to is a kind of environment-friendly type degumming agent and manufacture craft thereof.
Background technology
At optics, LED, crystal, shake in sub-field, often use the bonding opticglass of mixture and the crystal of shellac and gum rosin, this product can be peeled off the glass after bonding again, and cleans shellac and the gum rosin of removing opticglass and crystal surface.Degumming agent that existing cleaning is used is general, and what adopt is that the solvent-borne formulation of propyl carbinol, dehydrated alcohol, acetone coordinates and forms, what this product was used is dissolving technology, be that the organism such as dehydrated alcohol, acetone, propyl carbinol are the good solvent of shellac, gum rosin, therefore when selecting separated said two products as the glass substrate of tackiness agent, first can expect colloid to dissolve to reach separating effect; Although but above-mentioned solvent can dissolve colloid, dissolution time is long, separated slow and be not easy glass surface thoroughly to clean up, take effect slow, in addition, volatile, cause environmental pollution, the raffinate after simultaneously cleaning is danger wastes, and burning disposal easily causes dioxin to pollute.
Summary of the invention
For the deficiency existing in prior art, the object of the invention is to provide a kind of environment-friendly type degumming agent and manufacture craft thereof that water is basic components of take, react and become water-soluble substances with shellac, gum rosin, shellac, gum rosin are dissolved in the water rapidly to reach to the effect of glass substrate separation.
To achieve these goals, the present invention realizes by the following technical solutions:
A degumming agent, is characterized in that, its by mass percentage, comprise 95%～99% water,? 0.1%～0.5% promoting agent, 0.5%～4.9% organic acid.
According to above-mentioned environment-friendly type degumming agent, wherein, it comprises 99% water, 0.1% promoting agent, 0.9% organic acid by mass percentage.
According to above-mentioned environment-friendly type degumming agent, wherein, described organic acid is formic acid, acetic acid or oxalic acid.
According to above-mentioned environment-friendly type degumming agent, wherein, promoting agent is fatty alcohol type.
A kind of manufacture craft of environment-friendly type degumming agent, its processing step is: it by mass percentage, the water of 95-99% is joined in mixing vessel, then, in mixing vessel, be filled with nitrogen bubble, and add 0.5%～4.9% organic acid and 0.1%～0.5% promoting agent, after mixing, through accurate filter, filter final described environment-friendly type degumming agent.
As preferably, what described mixing vessel adopted is compounding kettle
The present invention adopts above-mentioned formula and technique thereof, and its beneficial effect is as follows:
1. the present invention is water system formula, adopts 99% for water, and reacting with shellac, gum rosin becomes water-soluble substances, shellac, gum rosin are dissolved in the water rapidly to reach to the effect of glass substrate separation, therefore not volatile, can not pollute, to process convenient simultaneously, is environmentally friendly machine.
2. the effect of separation of glasses substrate of the present invention, instant effect, reaction thoroughly, substrate noresidue, only need soak at a certain temperature and can reach separating effect in 5 minutes, and on glass substrate, do not have colloid residual, and existing product at least soaks more than 15 minutes, and residual Duo，Hou road need increase cleaning link.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, describe the present invention in detail;
Fig. 1 is the schema that environment-friendly type degumming agent of the present invention cleans glass substrate;
Fig. 2 is the fabrication processing figure of environment-friendly type degumming agent of the present invention.
Embodiment
For technique means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with embodiment, further set forth the present invention.
Embodiment 1:
What the present embodiment adopted is a kind of environment-friendly type degumming agent, and by mass percentage, it comprises 95% water, 0.1% promoting agent, 4.9% organic acid.
Embodiment 2:
What the present embodiment adopted is a kind of environment-friendly type degumming agent, and by mass percentage, it comprises 97% water, 0.4% promoting agent, 2.6% organic acid.
Embodiment 3:
What the present embodiment adopted is a kind of environment-friendly type degumming agent, and by mass percentage, it comprises 99% water, 0.1% promoting agent, 0.9% organic acid.
Referring to Fig. 2, being made as of the environment-friendly type degumming agent of above-described embodiment 1-3: it by mass percentage, the water of per-cent in above-described embodiment 1-3 is joined in mixing vessel, then, in mixing vessel, be filled with nitrogen bubble, and add promoting agent in organic acid in above-described embodiment 1-3 and above-described embodiment 1-3, after mixing, through accurate filter, filter final described environment-friendly type degumming agent.
Referring to Fig. 1, the environment-friendly type degumming agent that above-described embodiment 1-3 produces, clean and remove opticglass and the shellac of crystal surface and the experiment of gum rosin, its experimental procedure is, glass substrate is immersed in the environment-friendly type degumming agent that embodiment 1-3 produces, after for some time, checks substrate separation situation and glass substrate residue amount.
The degumming agent of the former solvent-borne formulation with propyl carbinol, dehydrated alcohol, acetone carries out same operation experiments, it is compared, the environment-friendly type degumming agent that above-described embodiment 1-3 produces has all generated water-soluble material after reacting with shellac, gum rosin, and this water-soluble material is proposed by a large amount of moisture, residual residue is processed, greatly reduce the processing quantity of waste, its instant effect, reaction thoroughly, substrate noresidue.
Through measuring, the environment-friendly type degumming agent that embodiment 1 produces only need soak at a certain temperature and can reach separating effect in 6 minutes; The environment-friendly type degumming agent that embodiment 2 produces only need soak can reach on separating effect and glass substrate for 8 minutes does not at a certain temperature have colloid residual, and the environment-friendly type degumming agent that embodiment 3 produces only need soak can reach on separating effect and glass substrate for 5 minutes does not at a certain temperature have colloid residual; And existing product formula soaks and within 25 minutes, to reach separated, use be the method for dissolving, take effect slower, not thorough, and residual Duo，Hou road need increase cleaning link.
