Description

Technical Field

[0001] The present invention relates to the technical field of putty compositions, and in particular to a preparation method and application of a putty composition. Background Art

[0002] Putty is a base material used for wall repair and leveling. Its primary purpose is to fill gaps and correct curvature deviations in the construction surface, laying the foundation for a uniform and smooth paint finish. Existing putty materials incorporate inorganic flame retardants to enhance the flame retardancy of putty products. While these enhance flame retardancy, they can also affect the product's thermal insulation and crack resistance, making it difficult to coordinate and improve these properties. Furthermore, the product's moisture resistance, heat resistance, and temperature stability are poor, limiting its effectiveness. Consequently, the present invention further improves these properties.

[0159] Comparative Example 9.

[0160] The difference from Example 3 is that no fiber-modifying agent is added.

[0161] Comparative Example 10.

[0162] The difference from Example 3 is that no hybrid aluminum silicate fiber liquid is added in the preparation of the modified fiber agent.

[0163] Comparative Example 11.

[0164] The difference from Example 3 is that no aluminum silicate fiber is added in the preparation of the hybrid aluminum silicate fiber liquid.

[0167] Comparative Example 13.

[0168] The difference from Example 3 is that no modifier is added during the preparation of the modified fiber agent.

[0169] The products of Examples 1 to 3 and Comparative Examples 1 to 13 were tested for flame retardancy, heat preservation, and crack resistance, as well as moisture resistance, cold and heat resistance, and temperature change stability (the products were placed under 10% humidity for 24 hours, then placed at 70°C for 12 hours, and finally placed at -5°C for 12 hours, the above being one cycle, and the cycle was repeated 10 times). The test results are as follows:

[0170]

[0171]

[0172]

[0173]

[0174] It can be seen from Comparative Examples 1 to 13 and Examples 1 to 3 that;

[0175] The product of Example 3 has excellent thermal insulation and flame retardancy, and at the same time has obvious crack resistance, significant performance coordination, and significant moisture resistance, cold and heat stability. It can be seen from Comparative Examples 1 to 13 and Example 3 that the performance of the products of Comparative Examples 1 to 13 has deteriorated to varying degrees, and the performance of the product of Example 3 of the present invention is the most significant.

[0176] From Comparative Example 1, Comparative Example 9 and Example 3, it can be seen that when neither the functional reinforcing improver nor the modified fiber agent is added to the product, the performance of the product deteriorates significantly. When the two are combined and coordinated, the performance effect of the product is most significant.

[0177] As can be seen from Comparative Examples 2 to 8 and Example 3, no illite-doped regulator was added in the preparation of the functional reinforcement-based improver, no mullite whisker liquid was added in the preparation of the illite-doped regulator, no mullite whiskers and wood cellulose were added to the mullite whisker liquid, no zirconium oxide and boron nitride were added to the mullite whisker liquid, no polytuning modifier was added in the preparation of the functional reinforcement-based improver, no sintered body was added to the polytuning modifier, and no pyrophyllite and nano-titanium nitride were added to the sintered body. The performance of the products all showed a trend of deterioration to varying degrees. The mullite whisker liquid and polytuning modifier obtained by the specific method of the present invention had the best product performance effect, and the functional reinforcement-based improver prepared by the specific process of the present invention had the most significant product performance effect.

[0178] From Comparative Examples 10 to 13 and Example 3, it can be seen that when the hybrid aluminum silicate fiber liquid is not added to the preparation of the modified fiber agent, the aluminum silicate fiber is not added to the preparation of the hybrid aluminum silicate fiber liquid, the bentonite liquid is not added to the preparation of the hybrid aluminum silicate fiber liquid, and the modifier is not added to the preparation of the modified fiber agent, the performance of the product has a tendency to deteriorate, and when the modifier is not added to the preparation of the modified fiber agent, the performance of the product deteriorates more significantly;

[0179] At the same time, the modified fiber agent obtained by the specific method of the present invention has the most obvious performance effect of the product, and the effect of using other methods instead is not as obvious as that of the present invention.

[0180] The present invention further explores the product performance through the preparation of the modifier;

[0181] Experimental Example 1.

[0182] The same as Example 3, except that cerium oxide was not added in the preparation of the modifier.

[0183] Experimental Example 2.

[0184] The same as Example 3, except that α-Al2O3 was not added in the preparation of the modifier.

[0185] Experimental Example 3.

[0186] The same as Example 3, except that cordierite powder was not added in the preparation of the modifier.

[0187] Experimental Example 4.

[0188] The same as Example 3, except that no carbon nanotubes were added in the preparation of the modifier.

[0189] The product performance tests of Experimental Examples 1-4 are as follows:

[0190]

[0191]

[0192] It can be seen from Experimental Examples 1-4 that when α-Al2O3 is not added in the preparation of the modifier, the performance of the product changes significantly. Secondly, when cordierite powder, carbon nanotubes and cerium oxide are not added in the preparation of the modifier, the performance of the product tends to deteriorate to varying degrees. At the same time, the preparation of the modifier is proprietary, and when other raw materials are used instead, the performance effect of the product is not as significant as that of the present invention. Only the modifier obtained by the specific method of the present invention has the most significant performance effect.

[0193] 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.

[0194] 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.
