It can be seen from the thermal conductivity of the material that the thermal conductivity of the rubber matrix of the conveyor belt is not much different from that of asbestos. From the perspective of the heat conduction mechanism of rubber composite, the properties and amount of filler material will also affect the heat insulation performance of rubber composite. The test results also show that the base film, the type film and the type film have good heat preservation performance. Base square, several types of film insulation performance is different from the filler, their rubber matrix is.

　　結(jié)果還表明，新型耐高溫和耐燒蝕硫化膜的隔熱效果基本相同，因為橡膠基體和填充材料基本相同。雖然橡膠基體的導(dǎo)熱系數(shù)與石棉相差不大，但其耐熱性遠(yuǎn)遠(yuǎn)低于石棉。因此，在考慮高溫輸送帶包膠配方時，考慮其耐熱性是很重要的。從橡膠復(fù)合材料的導(dǎo)熱機(jī)理,新型的耐高溫橡膠和耐燒蝕橡膠硫化電影有很多炭黑填充,形成導(dǎo)熱網(wǎng)鏈的填充材料組成,其隔熱性能主要是由填充材料,耐燒蝕涂膠添加少量聚酷短纖維有一個小對隔熱效果的影響的導(dǎo)熱系數(shù),聚酷短纖維和炭黑的導(dǎo)熱系數(shù)在一個,之間,也可以看到少量的聚醋短纖維的耐燒蝕橡膠絕緣。結(jié)果還表明，新硫化膜的隔熱效果與新硫化膜的隔熱效果基本一致。

　　The results also show that the heat insulation effect of the new high temperature resistant and ablation resistant vulcanized film is basically the same, because the rubber matrix and the filler material are basically the same. Although the thermal conductivity of rubber matrix is similar to that of asbestos, its heat resistance is far lower than that of asbestos. Therefore, it is very important to consider the heat resistance when considering the high temperature conveyor belt rubber coating formula. According to the heat conduction mechanism of rubber composite materials, the new high temperature resistant rubber and ablation resistant rubber vulcanized film have a lot of carbon black filling, which forms the filling material of heat conduction network chain. Its heat insulation performance is mainly composed of filling material. The heat conduction coefficient of ablation resistant coating with a small amount of polyurethane short fiber has a small influence on the heat insulation effect, and the heat conduction coefficient of polyurethane short fiber and carbon black is between, It can also be seen that a small amount of polyacetate short fiber is ablative resistant rubber insulation. The results also show that the heat insulation effect of the new vulcanized film is basically the same as that of the new vulcanized film.

　　橡膠帆布橡膠和聚酯/棉帆布隔熱性能很好,尤其是橡膠滌棉帆布是便宜的,可以考慮用于耐高溫輸送帶強(qiáng)化層絕緣從表中,你可以看到,厚度的一種新型的耐高溫橡膠和耐燒蝕橡膠硫化膜,通過隔熱效果可以使℃溫度下降到小℃以下。這些都給了我們一個啟示，耐高溫輸送帶可以考慮增加耐高溫橡膠層的厚度，或者增加隔熱補強(qiáng)層來降低輸送帶核心層和下橡膠層的加熱溫度。

　　Rubber canvas rubber and polyester / cotton canvas have good heat insulation performance, especially rubber polyester / cotton canvas is cheap. It can be considered to be used for high temperature resistant conveyor belt reinforcement layer insulation. From the table, you can see that the thickness of a new type of high temperature resistant rubber and ablation resistant rubber vulcanization film can reduce the temperature below ℃ through the heat insulation effect. All of these give us a revelation that high temperature resistant conveyor belt can consider increasing the thickness of high temperature resistant rubber layer, or increasing the heat insulation and reinforcement layer to reduce the heating temperature of the core layer and the lower rubber layer of conveyor belt.
