Definitions
- the invention relates to thermal insulation molded articles with a sheath, in particular thermal insulation boards based on pressed microporous thermal insulation material, and a method for their production.
- thermal insulation molded articles based on compressed microporous insulating material have a low strength and bend under mechanical stress or the usually one-sided heat effect and also easily crumble, they are provided with a protective layer on at least one side. Thermal insulation bodies of this type are particularly sensitive at the edges.
- thermal insulation bodies made of microporous or highly disperse ceramic thermal insulation materials on one or both sides with a metallic covering.
- a metallic covering With such coverings, the voids between the cover and the thermal insulation material cannot be minimized in the sense of optimal thermal insulation.
- the thermal insulation with all-round coating would be significantly reduced due to the relatively high thermal conductivity of the metals.
- a middle layer made of a first ceramic material is pressed from two sides with a cover layer of second ceramic material with a different structure.
- the cover layers are connected to one another by webs penetrating the middle layer.
- a border that can also be provided is provided.
- a layer of the second material is first precompressed with a layer of the first material spread over it under the action of pressure, projecting web and Edge punches penetrate the upper layer and create a recess in the lower one.
- the filled second material for the upper layer also fills the holes and depressions in the compacted plate.
- the edge as well as the webs consist of both material components.
- One of the objects of the invention is to impart an even greater homogeneity and strength to the casing. This further consists in creating an inexpensive heat-insulating molded article based on finely divided, microporous pressed thermal insulation material with all-round covering, which ensures optimum protection and thermal insulation and enables a method for its simple manufacture by means of a novel device.
- the object is solved by the features of claim 1.
- the method according to claim 6 also serves to achieve the object.
- the heat molded articles produced by the process according to the invention have the following advantageous properties, where:
- the scaffolding covering of the highly dispersed insulation layer and the relatively wide and stable heat-insulating edge give the heat insulation molded articles a high mechanical strength and ease of handling;
- the insulating edge of the cladding layers results in considerable savings in the expensive silica products of the middle layer.
- the method according to the invention can furthermore be carried out with the least mechanical outlay and enables the devices to be adapted in a simple manner to the respective dimensions of the thermal insulation molded parts.
- the invention is described using the example of a thermal insulation board and a process diagram using an apparatus according to the invention. Here show:
- Fig. 1 is a plan view of an inventive
- Fig. 2 is a press die of a lower tool
- Fig. 3-6 a second device with a conveyor belt
- the device shown in the drawing consists of two separate, but also interlinkable parts.
- a press with a fixed lower part, illustrated by a press mold or die 1, and a movable part, illustrated by a first press ram 3 Top.
- a press table 7 below the upper run of a conveyor belt 4 together with a chute 5, 6 and a sheath die 8 with a sharpened edge 8a below and a press ram 9 fitted into the sheath die 8 with a hose line leading to a switchable exhauster (not shown) 10th
- cladding layer A consisting of the layers A 'and A "according to FIG. 1, in particular expandable and / or layered minerals such as mica, pearlite, vermiculite or volcanic rock or a mixture thereof are used.
- aerogels in particular metal oxides such as pyrogenically produced silicas including arc silicic acid, low-alkali precipitated silicas, analogously produced aluminum oxide, titanium oxide and zirconium dioxide or a mixture of at least two of these highly disperse, microporous materials are suitable.
- Water glass is the preferred binder because it has relatively short curing times.
- Rock wool and glass fibers can be used as fiber additives for the outer layer A or the middle layer B.
- a 15 mm thick plate according to FIG. 1 with an area of 250 ⁇ 300 mm was produced by pressing the following mixtures at 1.0 MPa:
- a first mixture consisted of: 70% by weight vermiculite 30% by weight water glass
- a second mixture consisted of: 63% by weight of highly disperse silica, 34% by weight of ilmenite and 3% by weight of pearlite. It was:
- the second mixture for the middle layer B was applied to a press table 7 or a conveyor belt 4 guided above it in a predetermined thickness according to FIG. 3,
- the separated mixture part was also pre-pressed in the jacket die 8 by a second, smaller area press ram 9 according to FIG. 5,
- the plunger 9 was then set back somewhat upwards and a vacuum which made it possible to transport the mixture for the middle layer B was produced in the press space with the exhauster via the hose line 10,
- a mixture amount of the first mixture corresponding to the predetermined thickness of the upper covering layer A '' was then poured into the mold 1 and now, according to FIG. 8, all three layers A'-B-A '' with one another to a predetermined density of the heat insulating molded body at a pressure of 1.2 MPa, as can be seen in FIG. 9.
- a first mixture consisted of: 60% by weight vermiculite, and 40% by weight silica sol;
- a second mixture consisted of: 50% by weight of highly disperse silica, 25% by weight of zirconium silicate, 15% by weight of vermiculite, and 10% by weight of pearlite.
- the thermal insulation boards produced are notable for particularly high strength.
