The invention aims to fill gaps of the prior art, and provides the double-component flame-retardant silicone sealant for hollow glass. The sealant comprises the formula components by mass: a component A comprising 15-35 parts of alpha,omega-dihydroxy polydimethylsiloxane, 30-50 parts of a packing, 5-15 parts of methyl silicone oil, and 10-40 parts of an inorganic flame retardant; and a component B comprising 10-35 parts of carbon black, 10-50 parts of methyl silicone oil, 10-40 parts of a coupling agent, 5-15 parts of a cross-linking agent, 10-40 parts of polymethyl triethoxy silane, and 0.1-0.5 part of a catalyst. When in use, the two components are uniformly mixed and stirred with the mass ratio of the component A to the component B of 15:1. The sealant has flame retardancy and self-extinguishing character in the use process, thereby greatly promoting wide application of the double-component silicone sealant.
Description
Technical field
The present invention relates to a kind of silicone sealant and preparation method thereof, belong to sealing material technical field.
Background technology
From the Beijing Hotel in 1985 is used glass curtain wall at home for the first time, domestic glass curtain wall industry has obtained development fast, and the glass curtain wall technology of China has been gone to prostatitis, the world gradually.
On glass curtain wall, the main seal gum using mainly contains silicone structure sealant, butyl hot-melt glue, polysulfide sealant etc.Generally there are single-component and two kinds of two components as the silicone sealant of second sealing, for the former, the patent that application number is 201210037265.X provides a kind of one-component flame retardant silicone sealant and preparation method thereof, but because two component silicone sealants can be according to the factor such as environment, temperature, adjust arbitrarily set time, curing speed, construction simple etc., with respect to single-component silicone sealant, its advantage is obvious, therefore generally each large enterprises are all being used two component silicone sealants.But present stage, two component silicone sealants on the market did not generally have flame retardant effect, and that modern architecture requires fire resistance property is more and more higher, and the development with two component silicone insulating glass sealants of flame retardant effect just becomes certainty.
Summary of the invention
The object of the invention is to fill up current technology vacancy, two component flame-proof silicone sealants for a kind of double glazing are provided.
Technical scheme of the present invention is achieved in that two component flame-proof silicone sealants for a kind of double glazing, and the formula constituent of described seal gum is by mass:

Optimally, described carbon black is commercially available colour carbon black.
Preparation technology:
A component:
By α, alpha, omega-dihydroxy polydimethyl siloxane, filler, methyl-silicone oil, inorganic combustion inhibitor drops into and stirs 30-60 minute in stirrer, after be transported on shredder and grind by coupling device, guarantee that filler and inorganic fire-retarded filler are uniformly dispersed.Material after grinding is put into high speed dispersion stirrer or planetary mixer to be stirred and finds time, removes steam.Discharging after finding time 30-60 minute, packing.
B component:
First carbon black and methyl-silicone oil are put into stirring tank and stir, after stirring, use shredder to grind, guarantee that carbon black dispersion is even,
Ground carbon black and methyl-silicone oil are put into planetary mixer and once add poly-methyl three oxygen ethylsilane, linking agent, coupling agent, catalyzer to find time to stir 30-100 minute, discharging packing;
A, B component make rear preservation respectively, are mixed in proportion rear use when use.
When Main Function mechanism of the present invention is burning there is to decompose the surperficial heat of absorption combustionmaterial and reach fire-retardant object in inorganic combustion inhibitor.Sealing glue in use has flame retardancy and self-extinguishing, two component silicone sealant shortcomings that in use ubiquitous flame retardant properties is not up to standard, flame retardant properties is poor are solved, and the features such as that this product has is nontoxic, non-corrosiveness, environmental protection, thereby greatly promote the widespread use of two component silicone sealants.
