Abstract
A preparing method of an organosilicon defoamer specially used for gel laminated fire-resistance glass is disclosed. The preparing method includes following steps of: (1) adding a certain amount of hydrophobic silica and dimethyl silicone oil into a three-neck distillation flask, fully stirring for 20 min, adding dimethyl silicone oil, heating to 120 DEG C, and stirring intensely for 2 h to obtain silicone paste; and (2) cooling the obtained silicone paste to 70 DEG C, adding a compounded emulsifier in batches, stirring for 30 min, adding a stabilizing agent that is methylcellulose, and stirring and mixing for 2 h to obtain a finished product of the defoamer. The defoamer prepared by the preparing method has characteristics of good transparency, high thermal stability, high defoaming speed, long foam inhibition time, high-temperature resistance, and the like, can meet application requirements of the gel laminated fire-resistance glass, and effectively overcomes the bubble problem of the gel laminated fire-resistance glass.
Description
Technical field
The present invention relates to a kind of preparation method of silicone defoaming agent, be specifically related to a kind of preparation method of gel interlayer fireproofing glass special-purpose organic silicon defoamer.
Background technology
Flame resistant glass has that light transmission is good, intensity is high, fire-resistant, heat insulation, sound insulation, the feature such as ageing-resistant, be widely used in the aspects such as fire partition, fireproof partition, fire window, fire resistant doorsets.At present, on domestic and international market, flame resistant glass adopts grouting method gel-type transparent sandwich flame resistant glass mostly, due to reasons such as raw material, proportioning, production technology, temperature Change, the gel fire-resistance glass of current domestic production is in use or often occur bubble in depositing, split glue, rocket, the phenomenon such as bleach, have a strong impact on its apparent property, cause serious financial consequences and trouble to manufacturing enterprise, bring many puzzlements to application units.
Summary of the invention
The object of the invention is to, a kind of preparation method of gel interlayer fireproofing glass special-purpose organic silicon defoamer is provided, prepares the silicone defoaming agent being specifically applied to gel fire-resistance glass, suppress and eliminate in interlayer fireproofing glass gelinite to produce bubble.
The preparation method of described gel interlayer fireproofing glass special-purpose organic silicon defoamer, it comprises the following steps:
One, a certain amount of water delivery silica and dimethicone are added in there-necked flask, fully stir 20min, then add dimethicone, be heated to 120 DEG C, strong stirring 2h, obtain silicon cream;
Two, obtained silicon cream is cooled to 70 DEG C, adds composite good emulsifying agent in batches, stir 30min, then add stabilizing agent, be uniformly mixed 2h, obtain defoamer finished product.
The preparation method of gel interlayer fireproofing glass special-purpose organic silicon defoamer provided by the invention, its beneficial effect is, gained defoamer has that the transparency is good, heat endurance is high, antifoaming speed is fast, press down the bubble time grows and the feature such as high temperature resistant, the application requirement of gel interlayer fireproofing glass can be met, efficiently solve the air bubble problem of gel interlayer fireproofing glass.
Detailed description of the invention
Below in conjunction with an embodiment, the preparation method of gel interlayer fireproofing glass special-purpose organic silicon defoamer provided by the invention is described in detail.
Embodiment
One, a certain amount of water delivery silica and dimethicone are added in there-necked flask, fully stir 20min, then add dimethicone, be heated to 120 DEG C, strong stirring 2h, obtain silicon cream;
Two, obtained silicon cream is cooled to 70 DEG C, adds composite good emulsifying agent (Tween-80 and Span-60 forms compound emulsifying agent) in batches, stir 30min, then add stabilizing agent methylcellulose, be uniformly mixed 2h, obtain defoamer finished product.
