Problems solved by technology

However, the organosilicon sealant widely used on insulating glass in the prior art cannot reach a satisfactory level due to the effect of preventing water vapor from passing through, so that the service life of the insulating glass system cannot be guaranteed to meet the expected requirements. It largely restricts the application on insulating glass

Abstract

The invention discloses a preparation method of a sealant for insulating glass. The preparation method comprises the following steps: adding alpha, omega-dihydroxyl polydimethylsiloxane and methyl methacrylate into a vacuum kneading machine for kneading, wherein the vacuum degree is about 0.01-0.03 MPa, the kneading temperature is about 135-145 DEG C, and the kneading time is about 60-90 minutes, taking out the kneaded mixture at a sealed condition, putting the kneaded mixture in a vacuum reaction kettle with a stirring device, then adding basic zinc carbonate, zinc borate, quartz powder, silica powder, kaolin, triethoxyvinylsilane, gamma-methacryloxypropyltriethoxysilane and dibutyltin diacetate, controlling the vacuum degree to about 0.01-0.03 MPa, controlling the temperature to about 135-145 DEG C, controlling the stirring speed to 950-1050 r / min and controlling the stirring time to 90-120 minutes, and then packaging.

Description

Technical field [0001] The invention relates to the field of chemical coatings, in particular to a method for preparing a sealant for insulating glass. Background technique [0002] Insulating glass is composed of two or three pieces of glass, which are bonded and sealed around the periphery with an adhesive. The glass pieces are bonded to a metal frame containing a desiccant, such as an aluminum alloy frame, and an inert gas is filled between the glass layers to make A dry inert gas space is formed between the glass layers to make an efficient sound insulation and heat insulation hollow glass system. The hollow glass system has good heat insulation and sound insulation properties, is beautiful and applicable, and can reduce the weight of the building. It is a new type of building material. [0003] At present, the main problem of insulating glass in our country is its short service life, which is mainly manifested as: condensation or frost is easy to appear after a period of use,...
