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.

　　结果还表明，新型耐高温和耐烧蚀硫化膜的隔热效果基本相同，因为橡胶基体和填充材料基本相同。虽然橡胶基体的导热系数与石棉相差不大，但其耐热性远远低于石棉。因此，在考虑高温输送带包胶配方时，考虑其耐热性是很重要的。从橡胶复合材料的导热机理,新型的耐高温橡胶和耐烧蚀橡胶硫化电影有很多炭黑填充,形成导热网链的填充材料组成,其隔热性能主要是由填充材料,耐烧蚀涂胶添加少量聚酷短纤维有一个小对隔热效果的影响的导热系数,聚酷短纤维和炭黑的导热系数在一个,之间,也可以看到少量的聚醋短纤维的耐烧蚀橡胶绝缘。结果还表明，新硫化膜的隔热效果与新硫化膜的隔热效果基本一致。

　　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.

　　橡胶帆布橡胶和聚酯/棉帆布隔热性能很好,尤其是橡胶涤棉帆布是便宜的,可以考虑用于耐高温输送带强化层绝缘从表中,你可以看到,厚度的一种新型的耐高温橡胶和耐烧蚀橡胶硫化膜,通过隔热效果可以使℃温度下降到小℃以下。这些都给了我们一个启示，耐高温输送带可以考虑增加耐高温橡胶层的厚度，或者增加隔热补强层来降低输送带核心层和下橡胶层的加热温度。

　　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.
