The applicant finds, compare with known silicone sealant early, certain silicone sealant is used as following edge fluid sealant 13, sealing glue is arranged at has at least one internal tightness, in the multiple-glazing unit composite member 10 of the flexible plastic sheets 16 of generation thermal contraction, can make the no pleated time of this plastic tab keep longlyer.In addition, fluid sealant 13 pairs of ultraviolet rays in above-mentioned edge keep stable time also than the length of polyurethanes or polysulfide class.When above-mentioned window composite member 10 adopts silicone edge fluid sealant 13 to make, this moment sealing glue the thin slice creep under 71 ℃ of temperature through 500 hours after less than 0.018cm, be preferably under 71 ℃ of temperature through after 1000 hours less than 0.018cm, the plastic tab that thermal contraction then takes place is in tensioned state, and does not have pleated.In contrast, its thin slice creep under 71 ℃ of temperature through 500 hours after greater than the above-mentioned silicone sealant of 0.018cm owing in plastic tab, occur pleatedly, and consequent the unacceptable optical distortion of end user or fluctuating are damaged.
Though it is limited that following viewpoint does not have, but we still think, above-mentioned its thin slice creep is not comprising after through 500 hours a kind ofly greater than the silicone sealant of 0.018cm under 71 ℃ of temperature, or multiple composition with enough content is so that obtain acceptable thin slice creep properties.Can think that in carrying out the thermal contraction step process, or in window composite member useful life, after fluid sealant was hardened, mentioned component still had activity, can make fluid sealant change characteristic like this, and can in plastic tab, produce unacceptable distortion.Such as, can find that its thin slice creep is being included in composition or the plasticizing agent that still keeps active key to rearrange after the fluid sealant sclerosis after through 500 hours under 71 ℃ of temperature greater than some silicone sealants of 0.018cm; Or above-mentioned fluid sealant comprises the composition that plasticizing agent and key rearrange.Above-mentioned tightening, the flexible plastic sheets 16 that thermal contraction takes place is imbedded in the above-mentioned silicone edge fluid sealant 13 so that fix this plastic tab.If above-mentioned silicone edge fluid sealant can make the fixed end of plastic tab 16 lax, this moment, it was in tension state, then can produce undesirable pleated phenomenon.Because light characteristic is highstrung to any distortion, though very little so pleated, or fluctuating also can cause window defective.
Can find, around under the ambient conditions, such as can satisfy in hardenable silicone sealant component under the interior temperature atmospheric conditions under 71 ℃ of temperature through 500 hours after less than the less creep requirement of 0.018cm.Particularly, these silicone sealants are known single composition, or the indoor hardenable silicone sealant component of two composition, and this component is characterised in that it does not contain the composition that can make the thin slice creep surpass 0.018cm increasing after through 500 hours under 71 ℃ of temperature.The indoor hardenable silicone sealant component of two compositions can be used for following product, and the rate of hardening of this product is faster than single ingredient components.
Can think that the composition that the thin slice creep is increased is included in indoor hardenable component sclerosis and becomes the plasticizing agent that still keeps active behind the fluid sealant and/or silicone key composition again.Comprising less than the example of the silicone sealant component that is fit to of the edge fluid sealant of the thin slice creep of 0.018cm after through 500 hours under 71 ℃ of temperature as having: Dow Corning (R) 3-0117 silicone heat-protecting glass fluid sealant (back is called DC3-0117), it contains polysiloxane, calcium carbonate and MTMS (methyltrimethoxysilane); Dow Corning (R) 3145 RTV MIL-A46145 binder/sealants (back is called DC3145), it contains: hydroxy-end capped dimethyl siloxane, trimethyl silica, titanium dioxide and MTMS; Dow Corning (R) 995 silicone structure bonding agents (back is called DC995), it contains polysiloxane, calcium carbonate and methyl trimethoxy oxygen base silicon * *.These fluid sealant components are not included in the composition that still keeps active siloxane bond to rearrange after its sclerosis, or plasticizing agent.
When similar silicone sealant component comprises the composition that plasticizing agent and/or siloxane bond rearrange, their thin slice creep then under 71 ℃ of temperature through 500 hours after greater than 0.018cm.This product comprises Dow Corning (R) 982 silicone heat-protecting glass fluid sealants (back is called DC982), it contains the two composition products that are made of principal component and hardener, wherein institute's blending ingredients comprises hydroxy-end capped dimethyl siloxane, calcium carbonate, the orthosilicic acid orthocarbonate, γ aminopropyl-triethoxy monosilane, carbon black, dimethyl silicone polymer, two fourth tin dilaurates, dimethyl silicone polymer is used as plasticizing agent in the fluid sealant of sclerosis in addition, and two fourth tin dilaurates rearrange agent as siloxane bond; Dow Corning (R) 795 silicone building sealants (back is called DC795), it is single composition fluid sealant component, this component comprises hydroxy-end capped dimethyl siloxane, calcium carbonate, amorphous carbon/silicon dioxide, MTMS and dimethyl silicone polymer, wherein dimethyl silicone polymer is as plasticizing agent.The thin slice creep of above-mentioned DC982 and DC795 under 71 ℃ of temperature through 500 hours after greater than 0.018cm.The silicone sealant of other in the above-mentioned type comprises that its trade mark is GE SCS 2501
TMKnown, single composition silicone sealant, two composition fluid sealants, its trade mark are GE3204
TM, these two products are produced by General Electric Company.
When with DC3-0117, DC3145 and DC995 be during as silicone edge fluid sealant 13, their thin slice creep under 71 ℃ of temperature through 1000 hours after less than 0.018cm.In contrast, be damaged and thin slice creep that plastic tab wherein 16 produces pleated fluid sealant under 71 ℃ of temperature through only just surpassing 20 times of 0.018cm after 500 hours.
The window construction of the embodiment of the invention and make the method for window composite member and prior art described in similar.Its main difference point is: adopt above-mentioned silicone sealant component so that form edge fluid sealant 13, in sealing glue the thin slice creep of the silicone sealant of formed sclerosis under 71 ℃ of temperature through 500 hours after less than 0.018cm.Steam is easy to see through silicone edge fluid sealant; Therefore need provide to prevent that the insulated gas that is used for packing space 28 and 30 from running out of, and prevent that steam from entering the parts of above-mentioned space 28 and 30.Be used to prevent that gas from running out of a kind of parts that enter with steam is vapour barriers, trapping fluid sealant 24 and 26 as shown in FIG., or trapping sheet 25.Above-mentioned " trapping fluid sealant " refers to steam, or inert gas all can not pass through above-mentioned fluid sealant in a large number, thereby can change the function of formed window construction in the desired useful life of user.
