Comparative example 1
In comparison with example 1, the same amount of nano antimony trioxide was used instead of nano yttrium oxide in comparative example 1, and the rest was the same as in example 1. Namely, the modified filler of comparative example 1 was prepared without using nano yttrium oxide.
Comparative example 2
In comparison with example 1, the diphenyl dihydroxy silane was replaced with an equivalent amount of 2-carboxyethylphenyl hypophosphorous acid in comparative example 2, and the rest of the procedure was the same as in example 1. That is, in the preparation of the modified filler of comparative example 2, diphenyldihydroxysilane was not used.
Comparative example 3
In comparison with example 1, the amount of the ceramic slag in comparative example 3 was 55 parts, 5 parts of fly ash, and the rest of the components and the process were the same as in example 1.
Product effect test
The sound-insulating and heat-preserving fireproof boards prepared in example 1, example 3 and comparative examples 1 to 3 were cured at 30℃and 80% relative humidity for 14 days, and then tested for sound absorption coefficient according to the standing wave tube method, heat conductivity according to the standard JC275-1996, and flame retardance according to the standard GB 8624-2012, and the results are shown in Table 1.
TABLE 1
As can be seen from Table 1, the sound insulation, heat preservation and fire resistance of the sound insulation and heat preservation fireproof plate prepared by the examples are obviously better than those of the comparative examples 1-3.
As can be seen from the effect data of comparative example 1, when nano antimony trioxide was used instead of nano yttrium oxide, the sound insulation and heat preservation effects of the panel were significantly reduced. The reason is mainly that when the nanometer yttrium oxide is lacking, the mutual coordination of the nanometer yttrium oxide and the nanometer antimonous oxide is lacking, and the influence on the conduction of electrons and the dispersion of the nanometer antimonous oxide exists, so that the sound insulation and heat preservation effects of the board are reduced. The sound insulation and heat preservation performance is closely related to the electronic gain and loss or conduction function of the sound insulation and heat preservation performance, the invention fully utilizes the electronic gain and loss performance of the nanometer yttrium oxide, and the sound insulation and heat preservation performance of the sound insulation and heat preservation fireproof plate is improved by matching with the nanometer antimonous oxide.
As can be seen from the effect data of comparative example 2, the effects of sound insulation and heat preservation of the panel are not very significant after the flame retardant composition is changed, but the effects of flame retardance of the panel are significant. It follows that the present invention requires the simultaneous use of two specific flame retardant components to prepare modified fillers. The invention mainly uses 2-carboxyethyl phenyl hypophosphorous acid and diphenyl dihydroxysilane as flame retardant components to improve the flame retardant property of the board, and the nano antimony trioxide has certain flame retardance, but the main function of the nano antimony trioxide is to make the sound-insulation heat-insulation fireproof board obtain better sound-insulation and heat-insulation property after being modified by matching with the other components.
As can be seen from the effect data of comparative example 3, after the amounts of the ceramic waste residue and the fly ash are changed, the compatibility or dispersion uniformity of each component is remarkably affected, so that the sound insulation, heat preservation and fire prevention effects of the prepared plate are remarkably reduced. The ceramic waste residue is industrial waste residue, and can not be added infinitely in the utilization process, the invention can increase the increment of the ceramic waste residue to 50 parts by the combination of the modified filler and other components, but if the ceramic waste residue is further increased, even if the modified filler in the dosage of comparative example 3 and other components in the comparative example 3 are combined, the dispersion uniformity of each component is obviously deteriorated, so that the sound insulation, heat preservation and fire prevention effects of the sound insulation and heat preservation fireproof plate are obviously reduced.
From the effect data of examples 1 and 3, it can be seen that the sound-insulating and heat-preserving effects of the panels can be remarkably improved by adding the modified mica powder of the hydroxy polydimethylsiloxane and the silane coupling agent.
In addition, the sound-insulation and heat-preservation fireproof plate prepared in example 1 is tested for 28-day compressive strength according to the standard GB/T50081-2002, and the result is 25.1MPa, and the sound-insulation and heat-preservation fireproof plate has good mechanical properties.
