Abstract
The invention discloses a silicone rubber sealing gasket for a fire-proof seam, and relates to the technical field of rubber products. The method comprises the following steps: mixing the methyl vinyl silicone raw rubber, white carbon black and diphenyl silanediol in a kneading machine, controlling the temperature at 150 DEG C, performing heat treatment for 4 hours, adding magnesium hydrate, nano ceramic powder, sodium bicarbonate and quartz powder, and plasticizing in a double-roller machine so as to be prepared into a sizing material. The product is not deformed and tendered in long time under high temperature of flame, is not easy to drop from the seam under the action of external stress, and can prevent smog, flame and hot gas from penetrating through the seam; the fire-proof mixed silicone rubber can be prepared by adding magnesium hydrate and platinum complex material in a formula, a hard ceramic protective layer can be formed on the surface of the silicone rubber when the silicone rubber is in contact with the flame, so that the silicone rubber cannot drop from the seam.
Description
Technical field
The present invention relates to rubber item technical field, be specifically related to a kind of fire-resistant seam silicone rubber seal gasket and preparation method.
Background technology
Silicon rubber (English name Silicone rubber), minute heat vulcanization type (high temperature vulcanized silica gel HTV), room temperature vulcanized (RTV), wherein room temperature vulcanized is divided again polycondensation reaction type and addition reaction-type.High temperature silicon rubber is mainly for the manufacture of various silastic products, and room temperature silicon rubber is mainly to use as caking agent, Embedding Material or mould.Heat vulcanization type consumption is maximum, and heat vulcanization type divides again methyl silicone rubber, methyl vinyl silicone rubber, methyl ethylene phenyl siloxane rubber, and other also have eyeball silicon rubber, trifluoropropyl siloxane etc.In numerous synthetic rubber, silicon rubber is outstanding person therein.It has tasteless nontoxic, is not afraid of high temperature and resists the feature of severe cold, and " keeping cool ", " remaining calm " when 300 degrees Celsius and subzero 90 degrees Celsius, still do not lose original intensity and elasticity.Silicon rubber also has good electrical insulating property, oxytolerant resistance to deterioration, fast light resistance to deterioration and mildew resistance, chemical stability etc.So far, be cured and to become the rubber composition of silicon rubber well known, utilize the excellent character such as its weathering resistance, thermotolerance, winter hardiness, electrical insulating property, packaged material, coating material, the pattern that is widely used in electrical/electronic part such as uses at the formed material etc.At present, most silastic product is all the melting silicone rubber that uses solid-state version, mixes, then carry out hot press moulding moulding through opening refining.As fire-resistant seam silicone rubber seal cushion material in prior art, under hot environment, to be easily out of shape for a long time, embrittlement externally easily comes off under stress from seam.
Summary of the invention
Technical problem to be solved by this invention be to provide a kind of can be high temperature resistant, long-time indeformable silicone rubber seal gasket and preparation method for fire-resistant seam.
Technical problem to be solved by this invention realizes by the following technical solutions:
A preparation method for silicone rubber seal gasket for fire-resistant seam, its method steps is as follows,
By methyl vinyl silicon kautschuk, thermal silica and Diphenylsilanediol, mixing in kneader, temperature is controlled at 150 degrees Celsius, and thermal treatment is after 4 hours, add magnesium hydroxide, nano-ceramic powder, sodium bicarbonate and quartz powder to plastify on twin-roll machine, make sizing material.
The invention has the beneficial effects as follows: product of the present invention is under the high temperature of flame; indeformable for a long time; not embrittlement; externally under stress, be difficult for coming off from seam; can prevent smog, flame, hot gas from give a dinner for a visitor from afar through; this resistivity against fire melting silicone rubber can in formula, add magnesium hydroxide and platinum compound is prepared, and during contact flame, silastic surface can form firm ceramic protective layer, can from seam, not come off.
Embodiment
For technique means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with specific embodiment, further set forth the present invention.
Embodiment 1
A fire-resistant seam silicone rubber seal gasket, is comprised of the component of following weight,
During preparation: by methyl vinyl silicon kautschuk, thermal silica and Diphenylsilanediol, mixing in kneader, temperature is controlled at 150 degrees Celsius, and thermal treatment is after 4 hours, add magnesium hydroxide, nano-ceramic powder, sodium bicarbonate and quartz powder to plastify on twin-roll machine, make sizing material.
More than show and described ultimate principle of the present invention and principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; that in above-described embodiment and specification sheets, describes just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
