Problems solved by technology

The reason is that due to the three-glass two-cavity setting of the three-glass two-cavity insulating glass, it requires the tightness of the two cavities and the low moisture humidity in the two cavities.
However, in the current use process, affected by the environment, especially in the windy, rainy and humid areas in southern my country, the sealing of the edge of the glass on the outdoor side is quickly damaged, and water vapor penetrates, causing the desiccant to fail.
At the same time, the three pieces of glass are facing the surface of the two cavities. Because the sealing of the two cavities is damaged, it is easy to condense water mist. However, due to the installation structure of the three-glass and two-cavity insulating glass, it cannot be wiped, resulting in a decrease in light transmittance and loss of indoor space. The effect of heat
As a result, the service life of the three-glass two-cavity insulating glass is low, and it needs to be removed and replaced or repaired and reinstalled after a certain number of years of use.

[0064] Preparation process of a kind of anti-fog condensation three-glass two-chamber glass

[0065] A kind of production technology of three-glass two-cavity glass of water-proof fog condensation, it comprises steps,

[0066] S1: After the glass substrate is drilled, edged and tempered, a tempered glass plate is obtained;

[0067] S2: Apply anti-fog coating on both sides of the tempered glass plate successively to obtain an anti-fog coating. When the anti-fog coating on the tempered glass plate is cured, the tempered glass plate must be kept level, and one side of the same tempered glass plate has an anti-fog coating After curing, the anti-fog coating on the other side can be applied. When the anti-fog coating on both sides is cured, tempered glass can be obtained;

[0068] S3: Install the metal frame with three pieces of tempered glass, install sealing strips, seal with glue, and inflate to obtain a three-glass, two-chamber glass that is waterproof and foggy.

[0094]Anti-light aging test of anti-fog film layer

[0095] Put 5 pieces of the same tempered glass to be tested into the UV aging box for UV irradiation aging. The aging time is 72h. After the aging is accepted, the water mist condensation test and the [anti-fog film bonding force test] are respectively carried out.

[0096] The water mist condensation test is to place the aged tempered glass in a sealed constant temperature cabinet at 25°C, keep the dew point at 30°C, and keep the air circulation in the cabinet. The condensation area of ​​water mist on both sides shall be recorded as the average value of the two sides. The test results are shown in Table 5.

[0105] A kind of three-glass two-chamber glass with water-proof fog condensation, which is improved on the basis of Example 4, the difference is that cobalt chloride / silica gel particles are added to the anti-fog coating coated on both sides of the second glass plate .

[0106] Cobalt chloride / silica gel colloids are obtained through the following steps using sodium silicate, ammonium chloride solution, fatty alcohol polyoxyethylene ether and deionized water as raw materials,

[0107] T1: Dissolve fatty alcohol polyoxyethylene ether in deionized water to prepare a bottom solution, weigh a certain amount of sodium silicate and dissolve it in it to obtain a silicon-containing bottom solution;

[0108] T2: Heat and stir the silicon-containing bottom liquid, and at the same time add ammonium chloride solution dropwise to the silicon-containing bottom liquid until a white transparent gel appears, let the gel stand for one day and then wash it with deionized water until there is no ...

Abstract

The invention relates to a three-glass two-chamber glass, and discloses a three-glass two-chamber glass that is waterproof and foggy and condensed and its preparation process. parallel to each other, and each tempered glass is coated with an anti-fog film layer on both sides of the other tempered glass. After penetrating into the three-glass two-cavity glass, it cannot condense water mist with the glass surface, and maintain the light transmittance of the three-glass two-cavity glass to effectively prolong the service life of the three-glass two-cavity glass.

Description

technical field [0001] The invention relates to a three-glass two-chamber glass, in particular to a three-glass two-chamber glass waterproof and fog-condensed and a preparation process thereof. Background technique [0002] Three-glass two-cavity insulating glass is composed of three layers of flat glass. The three pieces of glass are bonded and sealed with the sealing strip and the glass strip with a high-strength and high-air-tightness composite adhesive around it. The middle is filled with dry gas, and the frame is filled with desiccant to ensure the dryness of the air between the glass sheets. Various glass original sheets and frames with different properties can be selected according to requirements (made by gluing, welding or welding. The gap between the three layers of flat glass makes it have a thermal insulation effect. At the same time, the choice of glass in the current technology, It makes the incident light of the three-glass and two-cavity hollow glass strong...
