Abstract

A packing paper used to improve the anti-mold performance of flat glass during storage and transportation. The paper liner is an anti-mold agent formulated with organic acids and dissolved salts containing divalent metal ions. The antifungal agent is directly added to the pulp or sprayed onto the newly formed paper to prepare a high-efficiency glass antifungal cushion paper. The pad paper can obviously improve the mildew resistance of the glass during storage and transportation, has the advantages of simple process preparation, no pollution, no irritating smell, no toxicity, and low cost.

Description

High-efficiency glass anti-mildew pad paper

The invention relates to a packing cushion paper for improving the mildew resistance of flat glass during storage and transportation.

Flat glass is prone to mildew during storage and transportation. The mechanism of mildew can be briefly described as monovalent sodium ions in the gaps of the glass structure network can spontaneously migrate from the interior of the glass to the surface. After a small amount of water is absorbed on the surface, white spots or Rainbow, that is, moldy glass. In order to improve the mildew resistance of glass, commonly used methods at home and abroad include gas treatment, salt treatment, acid treatment, amine and amide treatment, organic antifungal agent treatment, electrochemical treatment, sprinkler treatment, etc. Mold powder method and paper sandwich method, etc. The more paper sandwiching method currently used is to treat the pad paper sandwiched between the glass plates in the storage and transportation process with an antifungal agent. Japanese patent (patent 31-3684) and other introductions use amines and the like as antifungal agents, impregnated, sprayed, coated or infiltrated on the packing liner. my country's invention patent 89105376.X introduces that a powder mixture composed of adipic acid and polymethyl methacrylate is sprinkled on the surface of a glass plate. And another patent 92105098.4 introduces antifungal agent to add sulfuric acid press, ethanol, spices to form after acidic substance α-hydroxyisobutyric acid, acetic acid, oxalic acid, phosphoric acid are added for dissolving in water.

The mildew-proof mechanism of the anti-mold agent used in the above-mentioned flat glass anti-mold pad paper disclosed at home and abroad is mainly to improve the anti-mold of the glass by isolating the contact between water and the glass surface or by means of acid to neutralize the alkalinity of monovalent sodium ions on the glass surface. moldy.

The object of the present invention is to provide an anti-mold pad paper with high-efficiency anti-mold effect, which is simple in production method, cheap in price, non-toxic, harmless and free from environmental pollution. The anti-mildew mechanism of high-efficiency glass anti-mildew paper is to attach divalent metal ions to the anti-mildew paper sandwiched between the flat glass. When the divalent metal ions attached to the anti-mildew paper diffuse to the glass surface, it can The monovalent sodium ions inside the "pressed" glass spontaneously migrate to the glass surface, which fundamentally controls the mildew of flat glass during storage and transportation. The organic acid adopted in the present invention is also for neutralizing the alkalinity of the monovalent sodium ion on the glass surface, but has non-toxicity and no irritating smell, and wherein citric acid and malic acid are edible.

                             浓度：0.07～0.15mol/L酒石酸：

                 浓度：0.07～0.15mol/LThe antifungal agent used in the high-efficiency glass antifungal pad paper provided by the invention has a simple formula, and only needs to mix an organic acid and an inorganic dissolved salt containing divalent metal ions at a certain concentration, and then directly add it to the pulp or Spray onto formed paper. The organic acids used and their concentrations are as follows: Citric acid: Concentration: 0.07～0.15mol/L Malic acid:

Concentration: 0.07～0.15mol/L tartaric acid:

Concentration: 0.07～0.15mol/L

The inorganic soluble salt containing divalent metal ion and its concentration are as follows:

Copper sulfate: CuSO ₄ Concentration: 0.08～0.18mol/L

Cadmium chloride: CdCl ₂ ·2.5H ₂ O Concentration: 0.08～0.18mol/L

Cadmium nitrate: Cd(NO ₃ ) ₂ Concentration: 0.08～0.18mol/L

Nickel chloride: NiCl ₂ ·6H ₂ O Concentration: 0.08～0.18mol/L The L in the concentration unit mol/L means: the volume of the pulp liquid.

Example 1:

After mixing 0.07mol/L citric acid and 0.18mol/L copper sulfate evenly, add it directly to the pulp or spray it on the formed paper.

Example 2:

After mixing 0.15mol/L citric acid and 0.08mol/L copper sulfate evenly, add it directly to the pulp or spray it on the formed paper.

Example 3:

After mixing 0.1mol/L citric acid and 0.11mol/l copper sulfate evenly, add it directly to the pulp or spray it on the formed paper.

Example 4:

After mixing 0.1mol/L malic acid and 0.11mol/L copper sulfate evenly, add it directly to the pulp or spray it on the formed paper.

Example 5:

After mixing 0.1mol/L tartaric acid and 0.11mol/L copper sulfate evenly, add it directly to the pulp or spray it on the formed paper.

Embodiment 6:

After mixing 0.1mol/L citric acid and 0.11mol/L cadmium chloride evenly, add it directly to the pulp or spray it on the formed paper.

Embodiment 7:

After mixing 0.1mol/L citric acid and 0.11mol/L cadmium nitrate evenly, add it directly to the pulp or spray it on the formed paper.

Embodiment 8:

After mixing 0.1mol/L citric acid and 0.11mol/L nickel chloride evenly, add it directly to the pulp or spray it on the formed paper.
