[0143]

[0144]

[0145] It is concluded from Examples 1-3 and Comparative Examples 1-10 that

[0146] The product of Example 3 of the present invention has excellent tensile strength, limiting oxygen index and relative volume abrasion loss, and has excellent strength, wear resistance and flame retardancy. The performance of the product can be improved in a coordinated manner, and the product has a significant aging resistance and stability effect.

[0147] From Comparative Examples 1-6, Comparative Example 7 and Example 3, it can be seen that the product does not add one of the doped nano-silica-doped effect-enhancing agent and the lanthanum-modified effect-enhancing agent, and the performance effect of the product is significantly deteriorated. The two are used in combination and the synergy is the most significant.

[0148] The performance of the products tended to deteriorate when no nano-kaolin additive was added to the preparation of the nano-silicon dioxide-doped continuous effect adjuster, no additive was used in the nano-kaolin additive, no nano-silicon dioxide modifying liquid was used to treat the nano-silicon dioxide-doped continuous effect adjuster, no irradiated nano-silicon dioxide was added to the nano-silicon dioxide modifying liquid, and no yttrium nitrate solution and urea were added to the preparation of the nano-silicon dioxide modifying liquid. Only the nano-silicon dioxide-doped continuous effect adjuster prepared by the nano-kaolin treated with the nano-silicon dioxide modifying liquid obtained by the method of the present invention had the most significant product performance effect.

[0149] It can be seen from Comparative Examples 8-10 and Example 3 that when no whisker modification liquid is added to the preparation of the lanthanum-modified enhancer, no lanthanum-doped silicon carbide whisker is added to the whisker modification liquid, and no enhancer is added to the preparation of the lanthanum-modified enhancer, the performance effects of the products all tend to deteriorate. Only when the whisker modification liquid obtained by the method of the present invention is combined with an enhancer, the product performance effect is the most significant. The lanthanum-modified enhancers prepared by other process methods are not as significant as the effect of the present invention. At the same time, the inventors of the present invention found that when no enhancer is added to the preparation of the lanthanum-modified enhancer, the product performance also shows a significant deterioration trend.

[0150] Based on the above tests, the present invention finds that the performance enhancing agent has a greater impact on the performance of the product. Based on this, the present invention further explores it.

[0151] The preparation method of the effect-adjusting and strengthening agent is as follows:

[0152] Add 4 parts of boron nitride and 2 parts of silane coupling agent KH560 to 6.5 parts of 5% sodium dodecylbenzene sulfonate solution, then add 2.5 parts of aluminum silicate fiber and 1.5 parts of nano-silica sol, mix well and ball mill thoroughly. The ball milling speed is 1500r / min, and the ball milling is carried out for 2h. After the ball milling is completed, wash with water and dry to obtain an effective strength-adjusting agent.

[0153] Experimental example 1.

[0154] The only difference from Example 3 is that no aluminum silicate fiber is added in the preparation of the strength-adjusting agent.

[0155] Experimental example 2.

[0156] The only difference from Example 3 is that the silane coupling agent KH560 is not added in the preparation of the effect modulating agent.

[0157] Experimental Example 3.

[0158] The only difference from Example 3 is that no boron nitride is added in the preparation of the effect modulating agent.

[0159] Experimental Example 4.

[0160] The only difference from Example 3 is that no nano-silica sol is added in the preparation of the strength-adjusting agent, and deionized water is used instead of the sodium dodecylbenzene sulfonate solution.

[0161] The product performance tests of Experimental Examples 1-4 are as follows:

[0162]

[0163] It can be seen from Experimental Examples 1-4 that aluminum silicate fiber is not added in the preparation of the efficiency-adjusting and strengthening agent, and the performance of the product deteriorates significantly under normal conditions, and boron nitride is not added in the preparation of the efficiency-adjusting and strengthening agent, and the performance of the product deteriorates significantly under aging conditions. The coordinated cooperation of aluminum silicate fiber and boron nitride has a significant effect on improving product performance. At the same time, silane coupling agent KH560 is not added in the preparation of the efficiency-adjusting and strengthening agent, nano-silica sol is not added in the preparation of the efficiency-adjusting and strengthening agent, and deionized water is used instead of sodium dodecylbenzene sulfonate solution. The performance of the products all tends to deteriorate to varying degrees. Only the efficiency-adjusting and strengthening agent obtained by the method of the present invention has the most significant product performance effect, and the effects of other methods are not as obvious as those of the present invention.
