Description
Technical field
The present invention relates to the preparation method of engineering with flame resistant glass, specifically a kind of preparation method of gel interlayer fireproofing glass.
Background technology
Current clip stratotype flame resistant glass is all composite fireproof glass, is divided into water glass filled-type and gel-filled type flame resistant glass.The water-fast weathering resistance of water glass type flame resistant glass is poor, life-time service transparency variation.And the transparency of gel fire-resistance glass is good, water-fast, but while under sunlight long-term irradiation condition, using gel and glassy bond bad, and easily produce bubble, and then affect attractive in appearance and transparent.
Summary of the invention
The objective of the invention is to improve the prior art deficiency, by the composition of organic gel agent and the composition of additive in the change gel, cause transparent variation thereby make the gel interlayer fireproofing glass made under the sunlight long-term irradiation, not be prone to bubble in gel.
The present invention solves the problems of the technologies described above the technical scheme of employing to be: a kind of preparation method of gel interlayer fireproofing glass comprises following operation: the sheet glass of well cutting is cleaned up, then its edge sealing is made to the double glazing of interlayer, and reserved grout hole; The fireproof transparent gel is filled in double glazing and goes by grout hole, and the sealing grout hole, place 48h under 20 ~ 50 ℃ of conditions, makes its natural-crosslinked solidifying, and obtains finished product;
Described fireproof transparent gel is comprised of organic gel agent, linking agent, initiator, ammonium phosphate, magnesium chloride, sucrose, urea, thanomin and distilled water;
Described organic gel agent directly mixes gained by acrylamide and cationic monomer;

Described linking agent is N,N methylene bis acrylamide;
Described initiator is Potassium Persulphate or ammonium persulphate;
The preparation process of described fireproof transparent gel is:
1) take acrylamide according to the above ratio and cationic monomer is mixed and made into organic gel agent, then organic gel agent is dissolved in distilled water and makes the organogel agent solution, standby;
2) take according to the above ratio respectively linking agent, initiator, ammonium phosphate, magnesium chloride, sucrose, urea and thanomin, linking agent is dissolved in distilled water, after stirring and dissolving, slowly add successively while stirring load weighted ammonium phosphate, magnesium chloride, sucrose, urea and thanomin, Deng after the above-mentioned substance dissolving, add the initiator taken, then continue to stir to obtain clear solution, standby;
3) the organogel agent solution and the step 2 that step 1) are made) clear solution that makes mixes, and stirs 30min, and under the pressure conditions of 50-94kPa, degassed 2h, make the fireproof transparent gel;
Described step 2) in, in process for preparation, solution temperature is controlled within 10 ~ 30 ℃;
In described step 3), during degassed operation, the temperature of solution is controlled at 30-40 ℃.
In order to guarantee the performance of the gel interlayer fireproofing glass that the present invention makes, in described fireproof transparent gel, the percentage ratio that each component accounts for fireproof transparent gel total mass is preferably: acrylamide 8-16%, cationic monomer 1.8-3.2%, linking agent 1-4%, initiator 2-5%, ammonium phosphate 10-25%, magnesium chloride 9-18%, sucrose 4-15%, urea 3-20%, thanomin 5-20%, all the other are distilled water.
In the present invention, organic gel agent is dissolved in distilled water to the step of making the organogel agent solution and linking agent is dissolved in to the step in distilled water, the distilled water added be take and can be dissolved solute and be prerequisite, and the total amount sum of the distilled water added in two steps is the quality of distilled water in the fireproof transparent gel.
In the present invention, the degassed routine operation that is operating as, its objective is and prevent that the fireproof transparent gel from producing bubble when polymerization; After the grouting sealing, be cured polymerization, outside temperature is controlled between 20 ~ 50 ℃, in case too fast gel homogeneity and the transparent variation of causing of polymerization occur.
The product that the present invention makes is through national fire-proof construction material quality supervision and test Spot detection: flame resistant glass total thickness 20mm, the face that catches fire is continuing more than 76 minutes under the high temperature more than 1100 ℃, unexposed surface temperature still can remain on below 130 ℃, category-A II level fire resistance period requirement up to specification; Transparence 80(65) %, sinuousness 0.1(0.3) %, UV resistant irradiation behaviour 1(10) %, thermotolerance, winter hardiness, shock resistance etc. meet the requirements, with similar products at home and abroad, compare, reduced the weight of flame resistant glass unit surface, improve the over-all properties of flame resistant glass, reached domestic and international top standard.
Beneficial effect: 1. the flame resistant glass total thickness of the present invention's production only has 20mm, is less than 30 now current mm, effectively reduces the weight of product;
2. the flame resistant glass of the present invention's production face that catches fire is continuing more than 76 minutes under the high temperature more than 1100 ℃, and unexposed surface temperature still can remain on below 130 ℃, category-A II level fire resistance period requirement up to specification;
