Abstract
The present invention relates to mildew proof liquid of flat glass, and also relates to a manufacture method thereof. The mildew proof liquid is composed of buffer solution and substances which can form a thin film on the surface of the glass. The liquid of the present invention can be singly used, and can be combined with the existing common parting powder or packing paper to obtain better effect. The present invention can obviously delay mildew of glass, and can avoid the disadvantages that when clip paper or spray powder is singly used, paper finishes or spray marks, which are difficult to wash, are generated on the surface of the glass, etc.
Description
The invention relates to a glass mildew-proof liquid, which is suitable for glass mildew prevention, belongs to the class C03C, and can be used for online cleaning or non-online spraying of glass. The liquid can be used independently, and can also be used together with common packing paper or isolating powder when glass is packed in a box, so that the effect is better.
The invention discloses a glass mildew preventive and a preparation method thereof, which is characterized in that the glass mildew preventive and a mildew preventive are directly sprayed on a glass plate, the glass mildew preventive and the preparation method thereof are formed by mixing adipic acid and polymethyl methacrylate which are powdery mixtures, grinding, sieving and weighing the two components respectively to form a mixture, the defects of short mildew preventive time, hard scratch of glass powder, no easy scratch of glass powder, only a certain mildew preventive effect but no damage of glass pad, no scratch of glass pad, no corrosion of sodium propionate, no sodium propionate.
The invention aims to provide a glass mildew-proof liquid which has long mildew-proof time, is easy to clean and has a simple preparation method.
The invention is realized by the following technical scheme: the glass mildew-proof liquid is a buffer system composed of acidic buffer substance and substance capable of forming film on the glass surface, the acidic buffer substance is prepared from acetic acid, ammonium acetate and zinc acetate (or cadmium acetate), and the substance for forming film is composed of one of carboxymethyl cellulose, polyvinyl alcohol, pyrrolidone, hydroxyethyl cellulose and the like.
The glass is mildewed because of the alkali metal ions R in the glass+With H in aqueous solution+Or H3O+To carry out the exchangeReaction: with the progress of the reaction, the glass surface R+The pH value of the glass surface is continuously increased due to the fact that a large amount of (alkali metal ions) migrate outwards, so that the corrosion to the glass is accelerated, and therefore mildew stains appear on the glass surface. The pH value of the acidic buffer solution in the invention is stable, even if partial alkali is precipitated on the surface of the glass, the acidic buffer solution can be quickly neutralized by the acidic buffer solution to prevent the alkali from strongly corroding the glass, and the buffer solution after reaction can still keep the original pH value.
Meanwhile, Zn in the mildew-proof liquid2+(or Cd)2+) R separated from the surface structure of glass+(alkali metal ions) to enter the surface structure of the glass to stabilize the surface structure and prevent R+Further outward, thereby preventing the glass from going moldy.
In addition, a transparent film substance which can be hardly seen by naked eyes is formed on the surface of the glass by adding the mildew preventive solution, and the film substance prevents the surface of the glass from contacting with moisture in the air, thereby preventing mildew. Meanwhile, due to the existence of the film, the glass scratch-resistant coating plays a certain role in preventing glass from being scratched, and particularly avoids the defect of paper marks or spray marks on the surface of glass when wrapping paper is used or powder is sprayed. The film is very thin and almost invisible to the naked eye, has little effect on the appearance of the glass, and is a surfactant, together with Zn2+、Cd2+The glass is easy to clean together, so that the glass has no influence on the deep processing of the glass.
The preferred components of the glass mildew-proof liquid are (by weight percent): 0.1-5% of acid buffer substance, 0.2-6% of substance capable of forming film on the surface of glass and 89-99.7% of water, and the pH value of the mildew-proof liquid is controlled between 3.0-8.0.
The acidic buffer substance used in the mildew-proof liquid of the invention is preferably composed of (by weight percentage) 30% -80% of acetic acid, 15% -60% of ammonium acetate and 5% -10% of zinc acetate.
The acidic buffer substance used in the mildew-proof liquid of the invention is preferably composed of (by weight percentage) 20% -80% of acetic acid, 10% -50% of ammonium acetate and 10% -30% of cadmium acetate.
The material capable of forming a film on the surface of glass used in the mildew-proof liquid is one of carboxymethyl cellulose, polyvinyl alcohol, pyrrolidone, hydroxyethyl cellulose and the like, and the weight percentage of the material in the mildew-proof liquid is 0.2 to 6 percent.
The glass mildew-proof liquid can be uniformly sprayed on common packing paper on a paper making line, and then dried to prepare glass mildew-proof paper, and can also be matched with common glass isolation powder for use.
The on-line treatment cost of the mildew-proof liquid is lower than 0.015 yuan/square meter of glass. Whereas the method mentioned in CN2144137 costs no more than 0.02 yuan per square meter of glass for the mold-proof treatment.
The invention has the advantages that: because the invention can form a protective film on the surface of the glass, the contact between the surface of the glass and air and water is cut off, the mildew condition is cut off, and the glass is easy to clean as an active agent; additionally introducing Zn2+、Cd2+Plasma of Na on the surface of the glass+Ions migrate out and prevent the glass structure from being damaged, i.e. even ifCompared with the prior art, the invention has good mildew-proof effect, is easy to clean, overcomes the defect that paper lines or spray marks cannot be washed off on the surface of the glass when paper is wrapped or powder is sprayed, has certain scratch-proof effect, and has simple process and low cost.
Comparison of mildew-proof effect:
fresh glass with the size of 100 multiplied by 3mm is respectively treated by different mildew-proof methods, every four glass are in a group, are clamped by an iron clamp and are vertically placed in a temperature and humidity adjusting box with the temperature of 65 plus 2 ℃ and the relative humidity RH of more than or equal to 95 percent for testing. The detection results are as follows:
glass test sample glass mold onset time (hours)
Common glass sheet (without paper) less than 200
The common glass wrapping paper is less than 200
The glass-sandwiched mildew-proof paper is more than 400
The mildew-proof liquid coated by the invention is more than 550
The mildew-proof liquid of the invention is coated and then is sandwiched with the common packaging paper more than 800
