Abstract
A kind of manufacture method of multilayer asphalitine seal felt.For be coated with one deck adhered layer to seal felt, cooled asphalt felt is treated that at it surface of coating is heated to more than the fusing point, and then coat the stickup matter of heat.Interlayer connects and can improve thus, does not mix between thing layer and the thing layer, the malthoid quality also can not descend.
Description
The present invention relates to a kind of manufacture method of bituminous seal felt of multiple layer, particularly relate to a kind of tack seal felt.
Bituminous seal felt, especially for the bituminous seal felt of roof sealing, recent decades are known.The sealing felt by one in case of necessity through the dipping after liner make, this liner is the equal pitch in two sides generally speaking.But the surface spreading mineral material of seal felt or stick film can adhesion when the winding state to prevent the sunlight transmission and to make it.The general whole surface of described seal felt is all watered sticking with heated bitumen.
For ease of laying operation, as advising among the DE-GM1811068 that seal felt is provided with an auxiliary adhered layer.Thereby different sweat shape felt (Schwei bahn) or the automatic cold bonding subsides felts of obtaining of the performance of looking the alite paste that adopts.For making adhered layer thickness even, will paste matter usually and spread upon on the chilled seal felt.The seal felt that makes according to this method can satisfy general requirement.Because the variation of roof construction custom, big as building height, structure is lighter, the power that is applied on the deck obviously increases.Therefore it should be noted that seal felt is not under any circumstance all to be connected enough firmly with adhered layer, particularly smear when the seal felt that is provided with the separating layer of being made up of talcum powder, sand grains or film is surperficial all the more so when adhered layer.But stripping layer phenomenon can appear when adhered layer directly spreads upon on the cold state asphalt layer.
Above-described problem also has Bi Lu in DE-OS3413264.Here suggestion, with the directly two-sided heating after smearing adhered layer of seal felt that layering processes, cooling is so that can cement mutually between layer and the layer then.
Because the capacity of heat transmission of pitch is little, therefore need fruit that the malthoid that processes is heated to more than the fusing point again, so that bitumen layer can be melted in together fully.Because viscosity obviously descends, particularly the thing layer viscosity decline near the surface is very big, thereby causes the quality of seal felt to descend.
Because of spreading thing to small part is deposited in the bitumen layer, so malthoid gauge stability no longer can guarantee.If malthoid uses polyolefin film bonding as owing to the processing and fabricating technical reason in its surface, then this film damages because of heat effect.Therefore this known method could be achieved when adopting high-tech certain seal felt type of determining at the most.
Therefore, task of the present invention provides a kind of method of simple manufacturing multilayer asphalitine seal felt, this method is by being coated with common dissimilar seal felt with one deck pitch adhered layer, and adhered layer and malthoid are connected and the consequence that causes adhered layer viscosity to descend and cause the reduction of malthoid quality can not occur admixing mutually between layer and the layer.
According to the present invention; this task is finished in the following manner: a single or double scribbles obducent asphalt felt 1 and fully after the cooling it is being treated that the surface of coating is heated to 140-220 ℃ of temperature and promptly surpasses its softening temperature at least in short-term; and then the asphalitine or the non-asphaltene stickup matter 2 that with temperature are 140-220 ℃ heat are coated on the surface of thermal activation; with the malthoid that processes, be coated with where necessary and cool off behind the upper protective film 3 and roll.
Scribble obducent asphalt felt for single face, adhered layer is coated on the impregnated liner, in this case must thermal activation by the macerate of separating out in the liner or, if the malthoid surface is bonding with the thermal plastic film, then must be heated at least more than the thin unconcerned fusing point of thermoplastic materials.
For example to the two-sided asphalt felt that scribbles blanket layer, if adhered layer is coated onto on this blanket layer, then covering must thermal activation.Make the surface of coating spread talcum powder in this case or the spreading sand grains is all inoperative.For the bonding surface of plastic sheeting with sealing, this film is necessary-as previously mentioned-heat.The asphalt felt that the plastic sheeting that has hole is set for the bottom surface is also known by people, is not capped the surface spreading sand grains that thing hides this moment.In this case, this surface must be heated to the softening point temperature of higher fusing composition at least.Because of the capacity of heat transmission of pitch and the plastic sheeting that adopted is little, thus the asphalt felt surface may only be dissolved less than the degree of depth of 1/100mm, thereby do not reduce the fastness and the shape stability of malthoid.
Bitum covering can be used stuffing, and elastomer is or/and the thermoplastic materials plastics are improved, and these materials can not melt at their interface together with dissolving, simultaneously the sand grains that adheres to be wrapped up fully together with pasting matter.For the seal felt of prepared in accordance with the method for the present invention, the bonding at interface has improved the cohesion in the adhered layer.
If seal felt is done as sweat shape felt, then to paste matter and can make by air pitch or by the hard pitch that distillates, this moment, pitch did not preferably contain filler.Malthoid is generally bonding with a polyethylene film that approaches.To automatic cold bonding seal felt, then paste matter by making through the pitch of elastomer and tackifying resin improvement, this malthoid is fitted with detachable isolated film or barrier paper.
By accompanying drawing the present invention is further explained below.
Accompanying drawing is represented a device, and this device links to each other with the cooling device of a common caping malthoid equipment.The underrun infrared radiation device 4 of asphalt felt 1 is heated to 165 ℃ of surface temperatures, perhaps also can adopt an air-heater or direct combustion flame to replace infrared radiator.And then malthoid was led feed roller 5, smeared the hot sticky subsides matter 2 of 165 ℃ of thick temperature of the about 2mm of one deck for the malthoid coated on bottom side here, and this stickup matter 2 is by taking out of in the covering batch can 6.Malthoid after the coating passes from covering milling train 7, with more accurate malthoid thickness and obtain even curface.Then malthoid is turned to through revolving bed 8,, paste mutually with adhered layer and roll and close from the protective film 3 of debatching part 9 at the sweep of its first roller.Protective film can be thin plastic sheeting, and it can not link to each other with adhered layer with dissolving, or one is knock-down as the silicones isolated film.
Then seal felt is cooled off in normal way and the suspension arrangement by winding machinery carries out winding.This part of device do not drawn in the drawings, because of it is consistent with the appropriate section of common caping malthoid equipment.
