Comparative example 1
The only difference from example 1 is that the hollow glass microspheres in S1 are first modified hollow glass microspheres.
Comparative example 2
The only difference from example 1 is that the hollow glass microspheres in S1 are second modified hollow glass microspheres.
Comparative example 3
The only difference from example 1 is that no hollow glass microspheres were added.
Comparative example 4
The only difference from example 1 is that the second modified hollow glass microsphere in S1 was prepared by the following method: and (2) putting the second hollow glass microspheres into a stirrer, dropwise adding an ethanol solution of aminopropyltrimethoxysilane with the mass concentration of 8% while stirring, stirring for 24h, washing with ethanol for 4 times, and drying for 24h to obtain second modified hollow glass microspheres, wherein the mass ratio of the second hollow glass microspheres to the aminopropyltrimethoxysilane is 5.
Comparative example 5
The difference from the example 1 is only that the hollow glass microsphere in S1 is a modified hollow glass microsphere, and the hollow glass microsphere is prepared by the following method: mixing the hollow glass microspheres with an ethanol solution of phenyltrimethoxysilane and N- (beta-aminoethyl) -gamma-aminopropyltrimethoxysilane, stirring for 24 hours, washing with ethanol for 4 times, and drying for 24 hours to obtain modified hollow glass microspheres; in the ethanol solution of the phenyltrimethoxysilane and the N- (beta-aminoethyl) -gamma-aminopropyltrimethoxysilane, the mass concentration of the phenyltrimethoxysilane is 5 percent, and the mass concentration of the N- (beta-aminoethyl) -gamma-aminopropyltrimethoxysilane is 8 percent.
Carrying out tensile strength test on the rubber and plastic insulation boards obtained in the examples 1 to 6 and the comparative examples 1 to 5 according to the standard of GB/T528-2009 determination of tensile stress strain performance of vulcanized rubber or thermoplastic rubber; the noise reduction coefficient is tested according to GB/T16731-1997 (grading of sound absorption performance of building sound absorption products), and the test result is recorded in Table 1.
TABLE 1 tensile strength and noise reduction coefficient of rubber-plastic insulation board
As can be seen from table 1, the noise reduction coefficient NRC of the rubber and plastic insulation boards provided in embodiments 1 to 6 of the present invention reaches 0.90 to 0.95, and since the mass ratio of the first modified hollow glass microspheres to the second modified hollow glass microspheres in embodiment 5 is 1.
Because the hollow glass microspheres in the comparative example 1 are the first modified hollow glass microspheres and the hollow glass microspheres in the comparative example 2 are the second modified hollow glass microspheres, although the noise reduction coefficient NRC of the rubber and plastic heat-insulating board obtained in the comparative examples 1 to 2 is in the range of 0.90 to 0.95, the tensile strength is lower than that of the embodiment 1, the dispersibility of the two modified hollow glass microspheres in a system is better than that of a single modified hollow glass microsphere when the two modified hollow glass microspheres are mixed; the rubber and plastic heat-insulating board obtained in the embodiment 1 is compared with the rubber and plastic heat-insulating boards obtained in the comparative examples 1 to 3, and the fact that the first modified hollow glass microspheres and the second modified hollow glass microspheres are mixed for use is found out, so that the synergistic effect is achieved, the dispersibility of the hollow glass microspheres in the material is improved, and the mechanical property of the material is improved.
The comparative example 4 is different from the example 1 only in that N- (beta-aminoethyl) -gamma-aminopropyltrimethoxysilane used in the second modified hollow glass microsphere is replaced by aminopropyltrimethoxysilane in an equal amount, and the tensile strength of the obtained rubber-plastic insulation board is 5.5MPa and is lower than that of the example 1.
The difference between the comparative example 5 and the example 1 is only that the hollow glass microspheres are directly blended with ethanol solutions of phenyl trimethoxy silane and N- (beta-aminoethyl) -gamma-aminopropyl trimethoxy silane to modify the hollow glass microspheres to prepare the modified hollow glass microspheres, and the finally obtained rubber and plastic insulation board has the tensile strength of only 4.6MPa which is far lower than that of the example 1, so that the dispersibility of the hollow glass microspheres in a system is better and the tensile strength of the obtained rubber and plastic insulation board is optimal by the method for modifying the hollow glass microspheres provided by the invention.
The present invention is not limited to the above preferred embodiments, and any modifications, equivalent substitutions, improvements, etc. within the spirit and principle of the present invention should be included in the protection scope of the present invention.
