Description
Technical field
The present invention relates to a kind of obturator-type silicone rubber foam material and its production and use, belong to field of high polymer material processing.
Background technology
Silicon rubber foam material is a silicon rubber through the porousness macromolecular material of foaming back preparation, can be divided into closed pore, perforate and mix aperture silicon rubber foam according to the difference of foam structure.According to the type of preparation method and used silicon rubber, silicon rubber foam material can be divided into room temperature vulcanized silicone rubber foam and high-temperature silicon disulfide rubber foam, Lv Bailing, Liu Dengxiang, " practical rubber handbook, Beijing, Chemical Industry Press, 2001.It is base material that the room temperature vulcanized silicone rubber foam adopts the hydroxy-end capped silicon rubber of condensed type usually, and hydroxy silicon oil is a whipping agent, and platinum complex is a catalyzer, and sulfur foam obtains spongy elastomerics with holes under the room temperature.The room temperature vulcanized silicone rubber foam is applicable to the foam-in-site moulding, plays effects such as filling, sealing, damping; The traditional preparation process method of high temperature vulcanized foam silicone rubber is that silicon rubber, whipping agent and the vulcanizing agent uniform mixing that will contain microgranular inorganic filler make rubber unvulcanizate, by baking, foaming, make silicon rubber foam then.
The high temperature vulcanizable silicone foam, the characteristic of silicon rubber and foam materials is incorporated into one, the good characteristic that not only has silicon rubber, also have lower density, good absorption mechanical vibration or ballistic physical property, functions such as sound insulation, heat insulation, sealing, can be used as sealing, damping, insulation, sound insulation, heat insulation contour performance materials, have been widely used in fields such as communications and transportation, petrochemical complex, electronic industry, national defence and aerospace, Zhouning County's beautiful jade, " organosilicon polymer introduction ", Science Press, Beijing, 2000.Simultaneously, silicon rubber foam also has physiology inertia, nontoxic, odorless, nothing corrosion, and modulus is little, and softness and high resilience can be used as pharmaceutical factory, food factory is dry with liquid product or the sealing of large-scale drying plant and various filler rods etc.In automobile industry, automobile progressively improves with the requirement of weather strip to compression set, winter hardiness at present, and weather strip is tending towards lightweight, and feasible cry with the alternative existing terpolymer EP rubber foam materials of silicon rubber foam material increases day by day.Because silicon rubber foam anti-combustion in light weight, heat-resisting is the excellent material of fabric liner, can be used for the field that has heat and steam transmission and other foam materials can not satisfy performance requriements.
The preparation of high-temperature silicon disulfide rubber foam materials normally adopts superoxide to carry out sulfur foam, sulfidation and foaming process coupling are the keys of the foam materials of preparation foam structure and excellent property, but accomplish that this point is not easy very much, because whipping agent and peroxide vulcanizing agent are all very responsive to temperature, every rising 10 degree of temperature, the decomposition rate of vulcanization rate and whipping agent all is multiplied; In addition, peroxide vulcanizing agent is subject to the influence of whipping agent decompose residues, and the free radical passivation that acidic substance and the easy material that produces hydrogen make superoxide produce easily reduces cross-linking efficiency.In order to regulate the rate of crosslinking of superoxide, often need to add one or more vulcanization accelerators, the research with technology of filling a prescription repeatedly is to reach the coupling of rate of crosslinking and expansion rate.In addition, the homogeneity of peroxide crosslinking is subjected to the influence of its dispersion state in silicon rubber, particularly for rubber foam, thermal conduction is poor, and inside is heated and is slower than the top layer, often causes the top layer of sizing material and internal crosslinking degree varies to cause, foamy density is also inhomogeneous, and epidermis is thicker.
Summary of the invention
The objective of the invention is provides a kind of obturator-type silicone rubber foam material and preparation method thereof at the deficiencies in the prior art.Be characterized in silicon rubber is mixed with strengthening agent, whipping agent and other auxiliary agent and moulding, silicon rubber generation crosslinking reaction after electron beam or gamma-rays radiation, by heating whipping agent is reduced foaming then, it is crosslinked to adopt electron beam or gamma-rays to carry out secondary rays immediately after the silicon rubber foaming, with the over-all properties of further raising silicon rubber foam material.The silicon rubber foam material of present method preparation can be used as sealing, damping, insulation, sound insulation, lagging material.
