[0141] Comparative Example 1:

[0142] The difference from Example 3 is that no modified calcined talc is added.

[0143] Comparative Example 2:

[0144] The difference from Example 3 is that no composite liquid based on modified burned talc is added in the preparation of the modified burned talc agent.

[0145] Comparative Example 3:

[0146] The difference from Example 3 is that no composite body is added in the preparation of the composite liquid modified based on calcined talc.

[0147] Comparative Example 4:

[0148] The difference from Example 3 is that boron oxide and zirconium oxide are not added to the composite.

[0149] Comparative Example 5:

[0150] The difference from Example 3 is that no yttrium-sodium alginate was added in the preparation of the composite liquid modified based on calcined talc.

[0151] Comparative Example 6:

[0152] The difference from Example 3 is that sodium alginate and sodium silicate solution with a mass fraction of 6:5% are not added to the yttrium-sodium alginate body.

[0153] Comparative Example 7:

[0154] The difference from Example 3 is that no strontium titanate ball mill was added in the preparation of the modified calcined talc.

[0155] Comparative Example 8:

[0156] The difference from Example 3 is that no blending agent was added.

[0157] Comparative Example 9:

[0158] The difference from Example 3 is that no regulating liquid is added during the preparation of the conditioning agent.

[0159] Comparative Example 10:

[0160] The difference from Example 3 is that no wollastonite or sericite powder is added to the conditioning solution.

[0161] Comparative Example 11:

[0162] The difference from Example 3 is that zinc oxide and sodium carboxymethyl cellulose are not added to the conditioning solution.

[0163] The products of Examples 1 to 3 and Comparative Examples 1 to 11 were tested for light transmittance, impact resistance, and stain resistance under normal conditions and moisture and heat resistance conditions. The moisture and heat resistance conditions were as follows: the product was placed under 10% humidity for 24 hours and then at 70°C for 24 hours. The above was one cycle, and the cycle test was repeated 10 times. The test results are shown in Table 1.

[0164] Table 1 Test results of products of Examples 1 to 3 and Comparative Examples 1 to 11:

[0165]

[0166] From Comparative Examples 1-11 and Examples 1-3, it can be seen that the product of Example 3 has excellent light transmittance, impact strength, and stain resistance, and the three can be improved in a coordinated manner. In addition, the product has excellent moisture resistance and heat stability.

[0167] From Comparative Examples 1-11 and Example 3, it can be seen that when the present invention does not add the modified calcined talc agent or the blending agent, the performance of the product deteriorates significantly, especially under moisture and heat resistance conditions, the performance deterioration is more obvious;

[0168] The performance of the products showed varying degrees of deterioration when the modified calcined talc agent was prepared without adding a composite liquid modified with calcined talc, without adding a composite body to the composite liquid modified with calcined talc, without adding boron oxide and zirconium oxide to the composite body, without adding yttrium-sodium alginate body to the composite liquid modified with calcined talc, without adding sodium alginate and a 6.5% sodium silicate solution to the yttrium-sodium alginate body, and without adding strontium titanate ball mill bodies to the modified calcined talc agent.

[0169] The absence of yttrium-sodium alginate in the preparation of the composite liquid modified by calcined talc has a significant impact on the light transmittance of the product, while the absence of strontium titanate ball mill in the preparation of the modified calcined talc agent has significantly deteriorated the performance of the product. At the same time, the composite liquid based on calcined talc modified by combining yttrium-sodium alginate and composite obtained by the specific method of the present invention has the most significant performance effect, and the use of other methods instead is not as obvious as the effect of the present invention.

[0170] No regulating liquid was added during the preparation of the conditioning agent, wollastonite and sericite powder were not added to the regulating liquid, and zinc oxide and sodium carboxymethyl cellulose were not added to the regulating liquid. The performance of the products showed a trend of deterioration to varying degrees. The regulating liquid obtained by the specific method of the present invention had the most obvious performance effect.

[0171] The present invention further explores the product performance through the preparation of strontium titanate ball mill.

[0172] Experimental Example 1:

[0173] The same as Example 3, except that cordierite powder was not added in the preparation of the strontium titanate ball mill.

[0174] Experimental Example 2:

[0175] The same as Example 3, except that no silicon powder was added in the preparation of the strontium titanate ball mill.

[0176] Experimental Example 3:

[0177] The same as Example 3, except that no strontium titanate or nano-silica sol is added to the strontium titanate solution.

[0178] Experimental Example 4:

[0179] The same as Example 3, the only difference is that the dopamine hydrochloride solution is replaced by water.

[0180] The products of Experimental Examples 1 to 4 were tested for light transmittance, impact resistance, and stain resistance under normal conditions and moisture and heat resistance conditions. The moisture and heat resistance conditions were as follows: the products were placed under 10% humidity for 24 hours and then placed at 70°C for 24 hours. The above constituted one cycle, and the cycle test was repeated 10 times. The test results are shown in Table 2.

[0181] Table 2 Product test results of Experimental Examples 1 to 4:

[0182]

[0183] It can be seen from Experimental Examples 1-4 that when silicon micropowder is not added in the preparation of strontium titanate ball mill, the transmittance performance of the product deteriorates significantly; when cordierite powder is not added in the preparation of strontium titanate ball mill, the impact strength changes significantly; and when strontium titanate and nano-silica sol are not added to the strontium titanate solution, the strength, transmittance and anti-fouling properties of the product all tend to deteriorate; and when water is used instead of dopamine hydrochloride solution, the performance of the product also tends to deteriorate. Therefore, the strontium titanate ball mill prepared by the specific method of the present invention has the most significant performance effect of the product, and the effects of other methods are not as obvious as those of the present invention.

[0184] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced therein.

[0185] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
