Abstract

A method for reducing the staining of glass sheets during transportation and storage by applying a coating of a polymer having acid groups.

Description

Glass coating
The present invention relates to the protection of glass, relate to protection particularly plate glass.More specifically, the present invention relates to store and between the delivery period to the protection of glass surface.
As everyone knows, glass surface is easily contaminated, particularly for the glass of newly producing.The sign that occurs polluting is the iris that has on glass.When the glass-board surface opposite stacks, pollute remarkable especially.No matter whether interarea level, vertically or tilt to place, all can occur polluting.Under hot wet condition, occur especially easily polluting, under the weather condition of milder, occurring polluting also is its main shortcoming.
The present invention seeks to provide improving one's methods of a kind of protective glass surface by using the polymers soln that can reduce pollution of some amount.
Like this,, the invention provides the method on a kind of protective glass surface, comprising from considering on the one hand:
On the liquid carrier of the polymkeric substance that has acidic-group, form solution; With
With about 40 to about 500mg acidic-group/m 2The proportional spreading rate of (glass surface area) arrives glass surface with this solution coat, thereby has formed minimizing iridescent water-soluble coating.
Known method of the present invention for prevent glasswork (for example sheet glass) store and transportation in be subjected to polluting particularly useful, preferably this solution is storing and the aqueous solution (for example water) eccysis of transportation back.
Preferred acidic-group is carboxyl (COOH) and sulfo group (HSO 3).Relevant carboxylic group, for example the acyl substituted group also is useful, such as acid anhydrides.
Preferably, the proportional spreading rate of polymkeric substance is about 50 to about 500mg acidic-group/m 2(glass surface area).In the practical application, proportional spreading rate should satisfy the residing weather condition of glass (for example temperature and humidity).In general, under tropicalization, the proportional spreading rate of the upper limit of above-mentioned scope is preferred, and under the weather of milder, the proportional spreading rate of lower limit is preferred.
Typically, can be by the coating (usually with distilled water or softening water) of washing coating from the known region of glass off, and come titration (having used indicator) to measure proportional spreading rate as phenolphthalein indicator with sodium hydroxide or potassium hydroxide.For example, following column count can be used for polyacrylic acid:
Polyacrylic equivalent=72g
Equivalent=56.11g of KOH (also equals KOH solution or the 10000ml 0.1M of 1000ml 1M
KOH solution)
1.0g PAA=(10000/72)=138.88ml 0.1M KOH solution
Like this, the solution that contains 250mg PAA needs the titer of the KOH (or NaOH) of the 0.1M of 34.7ml, or every milligram of PAA needs the titer of 0.1388ml 0.1M KOH (or 1.388ml 0.01MKOH).For this being amounted to into every square metre processing horizontal, used following expression formula:
Processing horizontal (mg/m 2)=titer/(area (m 2) * 0.1388)
0.5m like this 2The area of sheet glass need the liter of 7ml 0.1M KOH to represent 100.8mg/m 2Processing horizontal (certainly, if use the KOH of 0.01M, same sheet glass will obtain the titer of 70ml).
In a preferred embodiment, the acid number of polymkeric substance is 500mg/g or higher, is preferably 600mg/g or higher.Acid number is preferably between 500-1000mg/g, between 600-800mg/g.For example, polyacrylic acid number is approximately 760mg/g KOH, and the acid number of polymethyl acrylic acid is approximately 652mg/gKOH.
Being used for polymkeric substance of the present invention can be homopolymer or heteropolymer.Preferred polymkeric substance is the polymkeric substance of acrylic or methacrylic acid.For example, can use polyacrylic acid or polymethyl acrylic acid.The sulfonic acid functional derivatives of polyolefine and polystyrene also is suitable.When polymkeric substance was heteropolymer, comonomer can be selected from propenal, the simple or branched-alkyl of acrylic or methacrylic acid (C for example 1-6Alkyl) or hydroxy ester, the ethenyl derivatives of benzene or toluene (for example styryl or cinnamyl), organic acid vinyl ester (C for example 1-6Vinyl carboxylates, as vinyl-acetic ester, vinyl butyrate and propionate) and maleic anhydride.
The molecular weight of polymkeric substance is between preferred upper and lower bound.In the limit of power that is chosen in those skilled in the art of these boundaries.Yet, if molecular weight less than about hundreds of, has seldom or does not have filming function.The upper limit of molecular weight can be up to millions of.Yet if about 600,000 height of molecular weight ratio, in solution, the too high sterically hindered concentration of wherein reactive carboxyl or other functional group that makes of polymer chain reduces.In the downstream processing of " Glass tubing group (glass stack) " (wherein glass surface is one of parts), wish that the solution of coating can be by eccysis.This selection to the molecular weight upper limit is influential, because along with the increase of molecular weight, easily solublization descends.In general, preferred molecular weight ranges is 10,000 to 600,000.
The preferred polymkeric substance that uses in the inventive method is that molecular weight is about 10,000 to about 600,000; 25 ℃, polymer concentration is 5% o'clock, and soltion viscosity (in water or organic solvent) is about 12 polymkeric substance (for example polyacrylic acid or polymethyl acrylic acid) to the acrylic or methacrylic acid of about 100 centipoises.
Can in any suitable manner solution coat be arrived glass surface.Can use tensio-active agent to assist the wetting of glass surface.Can use defoamer or foam preventer to suppress the foam tendency, foam can hinder the formation of polymer coating on the glass surface.In addition, can use dyestuff.Also can use other optional component, as long as they can not reduce the influence of acidic-group in the coating composition.
Typically, glass surface should be the part of sheet glass (for example sheet glass or floating sheet glass (float glasssheet)).
Further consider, the invention provides the sheet glass that has polymers soln (contain concentration sufficiently high be used to reduce iridescent acidic-group) coating at least one surface.Preferably, level of coverage is 40 to about 500mg acidic-group/m 2(glass surface area).Preferably, sheet glass obtains by the method for former definition.
