The non-woven structure is formed by oriented or random fibers, and the non-woven structure is formed by a process of forming a fabric without spinning a woven fabric, wherein the process is realized by only conducting oriented or random arrangement on short fibers or long fibers to form a fiber web structure and then reinforcing the fiber web structure by adopting mechanical, thermal bonding or chemical methods.
The thickness of the heat insulation plate is 2cm-15cm, and the density is 48-193kg/m 3 The thermal resistance value R of the thermal insulation board is more than or equal to 6mW/m.K, preferably more than or equal to 7mW/m.K.
The invention also provides a preparation method of the heat insulation board, which comprises the following steps:
1) Uniformly dispersing glass fiber, aerogel and black material in liquid to obtain mixed slurry;
2) Pouring the mixed slurry obtained in the step 1) on a die, and removing the moisture in the mixed slurry in a vacuum or pressing mode to form an aerogel modified glass fiber felt;
3) Applying an adhesive to the glass fiber mat obtained in the step 2), wherein the adhesive is uniformly distributed on the glass fiber mat through a liquid capillary migration principle;
4) And (3) placing the glass fiber felt in the step (3) in an oven or a hot press, curing at a high temperature of more than 200 ℃, and further removing excessive moisture to obtain the aerogel modified glass fiber insulation board.
The preparation method further comprises the following steps: and 5) decorating the heat insulation plate, wherein the decoration comprises the steps of coating color on the surface, and compositing a decorative surface on the surface, and preferably, the decorative surface is a film, coated paper, non-woven fabric, aluminum film pressed decorative surface or a stainless steel frame body.
In the aerogel modified glass fiber insulation panel of the present invention, the aerogel and the black material are uniformly distributed in the glass fibers. The black material acts as a blackbody radiator, and may be mixed with aerogel to act as a radiation absorber to reduce or inhibit heat or thermal energy transfer due to radiation. The aerogel preferably has a particle size of between 100 and 300 microns so that the aerogel particles are readily dispersed in the aqueous solution and so that water is readily expelled during the formation of the insulation panel. The water repellent may prevent water condensation and/or corrosion in the insulation panel.
The beneficial effects of the invention are as follows:
the aerogel modified glass fiber thermal insulation board has excellent thermal insulation, flame retardance and sound insulation performance, has better processing performance, is suitable for building isolation structures of businesses and houses, and can be also used in petroleum or natural gas refineries, chemical plants, automobiles, motor vehicles, ship bodies and aerospace structures; the method can be applied to the aspects of insulated residential or commercial buildings, structures or components, insulated petroleum or natural gas refinery components and/or structures, insulated chemical plant components and/or structures, insulated automobile parts and/or structures, insulated aviation parts and/or structures and the like.
The insulation panels of the present invention are low in density and lower density building panels generally exhibit lower heat release rates and smoke indices. The lower density aerogel construction panels have better sound suppression at higher frequencies, probably due to the increased sound absorption capacity of the more porous, lower density panels.
Detailed Description
The invention is further illustrated, but is not limited, by the following examples.
The experimental methods in the following examples are conventional methods unless otherwise specified; all raw materials are conventional in the technical field and are commercially available unless otherwise specified.
The aerogel modified glass fiber thermal insulation board disclosed by the invention comprises the following raw materials in parts by mass: 0-15wt% of coarse glass fiber, 10-40wt% of superfine glass fiber, 5-20wt% of adhesive, 42.5-76wt% of aerogel and 2.5-12wt% of black material; the average fiber diameter of the raw glass fibers is 8 to 20um, preferably 10 to 16um; the superfine glass fiber is glass fiber cotton or wool-like glass fiber, and the average fiber diameter is 0.5-6um, preferably 1-3um; the black material is one or more of carbon black, ferric oxide and titanium pentoxide.

2) Pouring the mixed slurry obtained in the step 1) on a die, and removing the moisture in the mixed slurry in a vacuum or pressing mode to form an aerogel modified glass fiber felt;
3) Applying an adhesive to the glass fiber mat obtained in the step 2), wherein the adhesive is uniformly distributed on the glass fiber mat through a liquid capillary migration principle;
4) And (3) placing the glass fiber felt in the step (3) in an oven or a hot press, curing at a high temperature of more than 200 ℃, and further removing excessive moisture to obtain the aerogel modified glass fiber insulation board.
5) The heat insulation board is decorated, the decoration comprises the steps of coating color on the surface and compositing a decorative surface on the surface, and preferably, the decorative surface is a film, coated paper, non-woven fabric, aluminum film pressed decorative surface or a stainless steel frame body.
The insulation boards of examples 1 to 12 of the present invention were prepared in the above manner, while the insulation boards of comparative examples 1 to 5 were prepared in the same manner, and the raw material ratios of the respective experimental groups are shown in table 1 (percentages are weight percentages). The aerogels in each experimental group of Table 1 were particulate silica aerogels having a particle diameter of 100 to 300. Mu.m, the average fiber diameter of the coarse glass fibers was 10 to 16. Mu.m, the average fiber diameter of the ultrafine glass fibers was 1 to 3. Mu.m, the binder was an organosilicon binder, and the waterproofing agent was a polysiloxane waterproofing agent. The black material of example 4 was iron oxide, the black material of example 7 was titanium pentoxide, and the black material of the remaining experimental group was carbon black.
The raw material components and proportions of examples 1 to 3, examples 4 to 6, examples 7 to 9 and examples 10 to 12 are respectively the same, and the heat insulation boards are manufactured by using different amounts of raw material slurries to be pressed into the same thickness, so that the density of the obtained heat insulation boards is different.
TABLE 1 raw material ratio of insulation panels
The properties of the prepared insulation panels were measured and the results are shown in table 2, in which,
the heat release rate test method adopts GB/T16172-2007 test method for heat release rate of building materials,
the test method of the thermal resistance value adopts GB/T10294-2008 'determination of steady state thermal resistance of heat insulating material and related characteristics-protection hot plate method',
the method for testing the sound absorption coefficient adopts GB/T18696.2-2002 (Acoustic-measurement of the sound absorption coefficient and the Acoustic impedance in an impedance tube-part 2): transfer function method.
TABLE 2
From the results of comparative examples 1 and 2 and the results of comparative examples 4 and 5, it can be seen that aerogel has a higher contribution to the thermal resistance value and also has a larger influence on the sound absorption performance.
From the comparison results of example 1 and comparative example 3, it can be seen that the addition of carbon black can increase the thermal resistance value, thereby improving the heat insulating property.
As can be seen from the results of comparative examples 4 and 5 compared with the examples, the addition of the black material and aerogel can significantly improve the thermal resistance and the sound absorption of the product, and the heat insulation performance and the sound insulation performance of the product are significantly improved.
The higher the heat release rate, the less likely it is to flame retardant, while the heat release rate of the insulation panels made in each experimental group in this example remained relatively constant.
