In the first embodiment, an inorganic material-wrapped polyphenyl particle aerogel composite thermal insulation and sound insulation system is shown in fig. 1-3 and comprises a composite layer, wherein the composite layer comprises a wall 10, a mortar leveling layer 11, a thermal insulation layer 12, a putty layer 13, a flexible smooth surface putty layer 14, an elastic closed bottom coating 15, a reflective thermal insulation coating layer 16 and a reflective thermal insulation coating facing layer 17, the mortar leveling layer 11, the thermal insulation layer 12, the putty layer 13, the flexible smooth surface putty layer 14, the elastic closed bottom coating 15, the reflective thermal insulation coating layer 16 and the reflective thermal insulation coating facing layer 17 are sequentially sprayed on the surface of the wall 10, the thermal insulation layer 12 is prepared by mixing glue powder and thermal insulation aggregates, and the glue powder comprises cement with the weight ratio of 140-, 3-7, a redispersible polymer powder, the insulating aggregate comprising: 5-10.5 polystyrene foam particles and 55-80.5 vitrified hollow microspheres, wherein the rubber powder materials in the weight ratio are weighed, stirred and mixed, the mixture passes through a 0.6mm square-hole sieve twice, the sieved rubber powder materials and heat-preservation and heat-insulation aggregate in the formula proportion are mixed, stirred and added with water, and stirred to prepare an electrodeless material coated polystyrene particle aerogel composite material mixture, the cement is conch P.O 42.5.5 grade cement, the particle size of the fly ash hollow microspheres is 0.1mm, an activator is a mixture of sulfate and a calcium-containing compound, the diameter of the polystyrene foam ink particles is 2-5mm, the stacking density is 12 Kg/cubic, the reflective heat-insulation coating facing layer 17 is any one of a granite-simulated type, a surface-simulated brick type, a real stone paint type, a napping type and a flat coating type, when the reflective heat-insulation coating facing layer adopts a flat coating process, a reflective heat-insulation coating layer does not need to be coated during construction, when no fly ash cenosphere is added into the whole mixed material, the influence of the organic-inorganic thermal insulation aggregate ratio on the fire-resistant and flame-retardant performance is realized when no fly ash cenosphere is added, under the condition that no fly ash cenosphere is used, the polyphenyl particle aerogel composite thermal insulation material (thermal cracking insulation) wrapped by the inorganic material is required to meet the fire-resistant requirement of A-grade non-combustibility, the number of the polyphenyl particles which can be added into the polyphenyl particle aerogel composite thermal insulation material (thermal cracking insulation) wrapped by the inorganic material is very small, and the mass ratio of the polyphenyl particles to the inorganic material is only 1: 14. The volume ratio of the polyphenyl particles to the vitrified hollow microspheres is about 1: 1.5 calculated according to the density of the polyphenyl particles being 12.1kg/m3 and the density of the vitrified hollow microspheres being 116kg/m3, when the fly ash hollow microspheres are used in the inorganic material-coated polyphenyl particle aerogel composite thermal insulation material (thermal insulation), the ratio of the polyphenyl particles to the vitrified hollow microspheres is obviously reduced, the fly ash hollow microspheres have obvious fire-resistant and thermal-insulation effects in the inorganic material-coated polyphenyl particle aerogel composite thermal insulation material (thermal insulation), and due to the addition of the additive, the volume ratio of the polyphenyl particles to the vitrified hollow microspheres is reduced from 1: 1.5 to below 1: 1.0. The reduction is significant because the larger the amount of the polyphenyl granules which can be used in the inorganic material coated polyphenyl granule aerogel composite thermal insulation material (thermal cracking insulation), the better the thermal insulation performance of the material, the smaller the crushing amount due to the small volume of the vitrified hollow micro-beads when the slurry is in construction, and the fly ash hollow micro-beads can improve the fireproof and non-combustible performance of the inorganic material coated polyphenyl granule aerogel composite thermal insulation material (thermal cracking insulation) because the spherical hollow structure and the vitrified thin-wall shell thereof reduce the density of cementing material components in slurry and improve the thermal insulation performance, the improved fireproof and non-combustible slurry component bonds the vitrified hollow micro-beads with the same fireproof and non-combustible performance in the inorganic material coated polyphenyl granule aerogel composite thermal insulation material (thermal cracking insulation), and the fireproof mortar formed by the vitrified hollow micro-beads and the vitrified hollow micro-beads bond the polyphenyl granules and coat the surface of the polyphenyl granules to form a fireproof layer, in a fire-resistant flame-retardant test, polyphenyl particles are prevented from being acted by high temperature of test flame, the inorganic material wrapped polyphenyl particle aerogel composite heat-insulating material (thermal cracking heat insulation) can meet the requirement of A-level non-combustible fire resistance, the surface layer of the polyphenyl particles is wrapped by the aerogel and condensed silicon through a certain process and method, so that the surface of the polyphenyl particles meets the A-level waterproof requirement, and the heat-insulating material disclosed by the invention meets the A-level waterproof requirement.
In example two, the fly ash cenospheres are added in the weight ratio of 5, 10, 15 and 20 respectively, as shown in fig. 4-5, and the results in the tables in fig. 4 and 5 show that the addition of the fly ash cenospheres has a little influence on the dry density of the inorganic material-wrapped polyphenyl particle aerogel composite thermal insulation material (thermal cracking insulation), but is not very large. This shows that the addition of the fly ash cenospheres increases the compactness of the inorganic material-wrapped polyphenyl particle aerogel composite thermal insulation material (thermal cracking insulation), that is, the density of the cementitious slurry body may be reduced after hardening, but a part of the added slurry body fills the gaps between the polyphenyl particles, so that the compactness of the inorganic material-wrapped polyphenyl particle aerogel composite thermal insulation material (thermal cracking insulation) is increased as a whole, the uniformity of the thermal insulation slurry body is improved by the change, and the thermal conductivity of the material is reduced, on the other hand, under a certain addition amount, the addition of the fly ash cenospheres increases the compressive strength and the compressive bonding strength of the inorganic material-wrapped polyphenyl particle aerogel composite thermal insulation material (thermal cracking insulation), but may have a maximum addition amount, and still remains to be tested, the compressive strength of each inorganic material-wrapped polyphenyl particle aerogel composite thermal insulation material (thermal cracking insulation) in the table in fig. 4 is not high, therefore, the condensed silica powder capable of remarkably exciting the activity of the cement-based material is used to improve the compressive strength, and the result is shown in a table in fig. 4, and the addition of the condensed silica powder can not only obviously improve the compressive strength of the inorganic material-coated polyphenyl particle aerogel composite thermal insulation material (thermal cracking insulation), but also improve the compression-shear bonding strength. The test result is in line with the action principle of the condensed silicon powder in the cement-based material.
In the third embodiment, the aerogel with different weight ratios is added to the inorganic material-wrapped polyphenyl particle aerogel composite thermal insulation material (thermal cracking insulation), and the test result of the influence of the aerogel on the thermal conductivity of the inorganic material-wrapped polyphenyl particle aerogel composite thermal insulation material (thermal cracking insulation) is as shown in fig. 6, in the table of fig. 6, the addition amount of the aerogel is increased from No. 1 to No. 5 in turn, thus it can be seen that the influence of the aerogel on the thermal conductivity of the inorganic material-wrapped polyphenyl particle aerogel composite thermal insulation material (thermal cracking insulation) is very significant. However, the addition of aerogels can have two adverse effects. Firstly, the aerogel is expensive, but the addition of the aerogel can obviously reduce the physical and mechanical properties of the inorganic material-coated polyphenyl particle aerogel composite thermal insulation material (thermal cracking thermal insulation). Thus, its addition should be kept within certain limits. In other words, the aerogel can only be used as an additive for improving the performance of the inorganic material-wrapped polyphenyl particle aerogel composite thermal insulation material (thermal cracking thermal insulation) and can not be used as a main material. The realization of the main properties (heat preservation and heat insulation performance and A-level non-combustible performance) of the inorganic material wrapped polyphenyl particle aerogel composite heat insulation material (heat preservation and heat preservation) is realized by polystyrene foam particles, vitrified hollow microspheres, fly ash hollow microspheres, condensed silica fume and other materials, the construction workability of the inorganic material wrapped polyphenyl particle aerogel composite heat insulation material (heat preservation and heat preservation) is high, in the inorganic material wrapped polyphenyl particle aerogel composite heat insulation material (heat preservation and heat preservation), the quantity of cementing material slurry is large due to the addition of the vitrified hollow microspheres, the fly ash hollow microspheres, the condensed silica fume and the aerogel, and the construction workability of the material is excellent. In the test process, the mixture is found to have good cohesiveness and high thixotropy, and is easy to carry out operations such as batch coating, trowelling and the like. The easy operation and the constructability are difficult to achieve by the glue powder polyphenyl particle inorganic material coated polyphenyl particle aerogel composite thermal insulation material (thermal cracking insulation) and the inorganic thermal insulation mortar, and the test results and the analysis thereof are combined to know that polyphenyl particles with larger volume can be added into the inorganic thermal insulation mortar through the introduction of the fly ash hollow microspheres, and the obtained inorganic material coated polyphenyl particle aerogel composite thermal insulation material (thermal cracking insulation) has the required A-grade non-combustible performance, the heat conductivity coefficient is also obviously reduced, the physical and mechanical properties are correspondingly improved, and the constructability of the mixture is very good; through the addition of the aerogel, the inorganic material-wrapped polyphenyl particle aerogel composite thermal insulation material (thermal cracking insulation) has a lower heat conductivity coefficient, the volume coefficient of the inorganic material-wrapped polyphenyl particle aerogel composite thermal insulation material (thermal cracking insulation) refers to the volume of a mixture of a unit volume inorganic material-wrapped polyphenyl particle aerogel composite thermal insulation material (thermal cracking insulation) after condensation and hardening, the volume coefficient of the glue powder polyphenyl particle inorganic material-wrapped polyphenyl particle aerogel composite thermal insulation material (thermal cracking insulation) is generally considered to be 0.75-0.80, the inorganic thermal insulation mortar is low in volume coefficient due to the fact that vitrified micro-beads are broken in the mixing engineering, and the five-organic material-wrapped polyphenyl particle aerogel composite thermal insulation material (thermal cracking insulation) is uniform in material internal structure, compact and high in volume coefficient and is more than 0.85. The visual benefit of high volume coefficient is the same quantity of products, the heat preservation layers with the same thickness are constructed, and the constructed area is larger. For example, if the thickness of the insulation layer is designed to be 40mm, when the volume factor is 0.8, the polystyrene particle aerogel composite insulation material (thermal cracking insulation) coated with the inorganic material per cubic meter can be constructed by 25 square meters in theory, but the construction area is only 20 square meters in practice. If the volume coefficient is 0.85, the construction area can reach 22.5 square meters.
The foregoing shows and describes the general principles and broad features of the present invention and advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed.
