Abstract

The invention relates to a colored sandwich glass and its production method. It is characterized by that the elastic transparent intermediate layer of said sandwich glass is colored, and is formed from 48-60% of methyl methacrylate and 0.05-0.1% of base color organic dye. Said production method features that before pulping, the base color organic dye to be used is prepared according to a certain proportion, and dissolved in 2-5% butyl alcohol. Said invented product can ensure brilliancy to its color and durable, and said method is low in cost, simple and easy to implement.

Description

A kind of colour sandwich glass and production method thereof

The present invention relates to a kind of transparent laminate.

As everyone knows, laminated glass is a kind of transparent glass--middle layer--glass laminates that two sheet glass good bond is formed with transparent elastic film.This published in " Shanghai science tech publishing house " in June, 1985, had done many descriptions in " aeronautical material " chapter 12 of being write by Beijing Inst. of Aeronautical Materials.Its physical strength height, transparent, heat-resisting, wear-resisting.During destruction,, can prevent the danger that fragment wounds, thereby be called as " shatter proof glass " because glass is clung by the middle layer and do not fragmentate.Laminated glass is as a kind of safe finishing material, being accepted by increasing people at present, mainly is that it is applied on the glass curtain wall, skylight, ceiling, partition, safe antitheft door and window, commodity display kitchen window of commercial building, hotel, restaurant's contour level building.But, when people need colour sandwich glass, then often still adopt colored glass to do former, realize it with the transparent elastic film is bonding.Like this, certainly will be the glass what color is arranged, could make the laminated glass of what color.And because stained glass is exposed outdoor, wind and weather life-time service, the defective that has color to come off unavoidably.At present, the stained glass cost of domestic glass manufacturer production is high and have only orchid, tea, green etc. several, far can not satisfy the needs in market.Chinese patent 87103395 discloses a kind of photopolymerisable laminated safety glass, and disclose its interlayer and can manifest certain color, but its details and unexposed.In sum, these reasons have limited the production and the use of colour sandwich glass greatly.

The object of the present invention is to provide the method for a kind of colour sandwich glass and production thereof.Simple, with low cost when producing this colour sandwich glass, when using this colour sandwich glass, it can guarantee bright-colored brilliant, durable prolonged and do not come off.

Technical solution of the present invention is as follows: adopt two can be that the white transparent glass of all size, various thin and thicks is done former, the transparent film of configuration elasticity fills does the middle layer, and two sheet glass good bond are formed.Be characterized in that it is that elastic film is chromatic that this middle layer is colour, and comprise account for raw material weight 48-60% methyl methacrylate as body material, the primary colours organic dye that accounts for 0.05-0.1% is as center material.Because dyestuff is organic substance, when mixing, exist certain resistance gather power with organosilane ester, therefore must organic dye be dissolved first butanols, and then be filled in other solvent and go with 2-5%.The present invention selects for use the first machine vinylformic acid of 1-5% to do toughener, so that the middle layer has certain rigidity.Selecting Diisopropyl azodicarboxylate and the peroxidation formyl of 0.5-4% for use is initiator, to weaken intermolecular forces, make its preferably with the dyestuff phased soln.The vinyltriethoxysilane of selecting 1-3% for use is a coupling agent, to promote film bonding.Other then is a softening agent, can select dimethyl phthalate and dibutyl phthalate for use.

Accompanying drawing is seen in technical process of the present invention.

The invention has the advantages that: the colored restriction that is not subjected to original sheet glass, can configure various depth distinct colors according to user's needs, and colored film places between the white glass, use durable can not fading and come off.Because pyritous influence when dyestuff is not subject to processing glass during the configuration color, the fluorescent performance of organic dye has no to destroy, so its color and luster remains bright-coloured, lucid and lively.In addition, what use owing to film glass up and down is a large amount of is general common white glass, thereby greatly reduces the production cost of colour sandwich glass of the present invention, approximately reaches about 30 percent.Decorate in that the large glass curtain is strong, if adopt the colored sheet glass of selling in the market to make laminated glass, dull coloring not only then, and also volume is big, Heavy Weight, price are also high.Compare with a large amount of 5 mm thick colored sheet glasses that use on the market, if the present invention selects for use the common white glass of 3 mm thick to do former, the laminated glass weight of producing so will alleviate 25-40%.This is very favourable to the design of large glass curtain wall undoubtedly, can quicken applying of glass curtain wall.The national already glass quality supervision and inspection of the colour sandwich glass center that the present invention produces is detected, and conclusion is for " its anti-width of cloth all reaches the requirement of GB 9962-88 standard techniques according to property, thermotolerance, shock resistance, and it is qualified to judge.”

The embodiment of the invention 1, this embodiment is applicable to the decoration of indoor partition, roof, door and window.Be limited to indoor environment, require to have certain intensity and reach fluorescent transparency preferably, so following prescription is selected in the middle layer for use:

Methyl methacrylate 48-60%

Primary colours organic dye 0.05-0.1%

Butanols 2-5%

Methacrylic acid 1-5%

Diisopropyl azodicarboxylate 0.5-4%

Vinyltriethoxysilane 1-3%

Dibutyl phthalate all the other

At first glass cutting being become desired size, obturages, is in the milk with waiting for after the clamp with the edge sealing adhesive tape in edging, clean, dry back.Secondly, Organic Chemicals is prepared in proportion be dissolved in the container.In the present embodiment, used primary colours organic dye is red and blue, and they are dissolved in butanols by 37 to 63, refilter in the above-mentioned container, heat 80-85 ℃, 10-15 minute vacuumized 30-40 minute after reducing to room temperature then, in slurries till the no bubble.Then area, the intermediate layer thickness by required glass calculates required grouting amount, the polymerization of being in the milk, obturaging, heating.Concrete operations are since 40 ℃, keep 6 hours when rising 5 ℃ to 60 ℃ per half an hour, rise 5 ℃ to 85 ℃ per again half an hour and keep 4 hours, rise 5 ℃ to 100 ℃ per again half an hour and keep 2 hours.Stop heating back and be cooled to 40 ℃ under the polymerization furnace situation not opening, open fire door then and take out glass.This glass is purple laminated glass required in the present embodiment.Its cleaning is cleaned, test, can pack after qualified and dispatch from the factory by GB.

The embodiment of the invention 2, this embodiment is applicable to outer decoration, the decoration of buildings.Outer decoration need have oxygen and the action of ultraviolet ray in Chinese People's Anti-Japanese Military and Political College's gas, need certain low temperature flexibility and shock resistance, thereby following prescription is selected in its middle layer for use:

Methyl methacrylate 50-60%

Primary colours organic dye 0.05-0.1%

Butanols 2-5%

Methacrylic acid 1-5%

Peroxidation formyl 0.5-4%

Dimethyl phthalate 20-16%

Dibutyl phthalate all the other

The production technique of this prescription is identical with embodiment 1.But the primary colours organic dye in the present embodiment is selected yellow and blueness for use, and they are dissolved in butanols by 70 to 30, refilters in the container.It is final like this that what obtain is the required green laminated glass of this example.Certainly, the organic dye total amount is less than normal, and the color that obtains is then shallow partially; The organic dye total amount is bigger than normal, and the color that obtains is then dark partially.In a word, when we with the organic dye of red, yellow, blue three kinds of primary colours by different total amounts, when different ratios is prepared, just can obtain the colour sandwich glass of the different variety of colors of the depth.
