Example 3
The application also provides a preparation method of the thermal diffusion layer, the thickness of the thermal diffusion layer is 1-5mm, and the thermal diffusion layer is prepared from the following raw materials in parts by weight: 30 parts of polypropylene powder, 10 parts of nano-alumina, 2 parts of a silane coupling agent and 0.3 part of nano-graphene.
Examples 4 to 7
Examples 4 to 7 differ from example 3 in the amount of each raw material component used in the thermal diffusion layer, see table 1 for details.
Comparative examples 1 to 6
Comparative examples 1 to 6 differ from example 3 in the amount of each raw material component of the thermal diffusion layer, see table 2 for details.
Comparative example 7
Comparative example 7 is different from comparative example 3 in that the thermal diffusion layer is made of raw materials including, by weight: 30-50 parts of polypropylene powder, 10-15 parts of aluminum oxide, 2-4 parts of silane coupling agent and 2-4 parts of nano graphene, namely, the aluminum oxide is used for replacing the nano aluminum oxide.
Comparative example 8
Comparative example 8 is different from comparative example 3 in that the thermal diffusion layer is made of raw materials including, by weight: 30-50 parts of polypropylene powder, 10-15 parts of aluminum oxide, 2-4 parts of silane coupling agent and 0.2-0.4 part of nano graphene, namely, the nano graphene is replaced by the graphene.
Comparative example 9
Comparative example 9 is different from example 1 in that the heating panel in comparative example 9 is not coated with a heat diffusion layer.
The raw material components of the above examples 3 to 7 and comparative examples 1 to 8 were uniformly stirred at 70 to 90 ℃ and extruded through an extruder to obtain a thermal diffusion layer, and the thermal diffusion layer prepared in the above examples 3 to 7 and comparative examples 1 to 8 was coated on a heating plate, and then the performance of the thermal diffusion layer was tested according to GB/T3139-2005, with the test results shown in table 3.
Table 1 examples 3-7 amounts of respective raw material components in the thermal diffusion layers
Table 2 comparative examples 1 to 6 amount of each raw material component used in the thermal diffusion layer
Table 3 results of performance tests of examples 3 to 5, and comparative examples 1 to 8
Referring to table 3, the thermal diffusion layer in examples 3 to 7 has a good heating effect and high heat transfer efficiency, so that the effect of saving energy is achieved, heat transfer is uniform, the protective film on the glass is heated more uniformly, and the phenomenon of glass breakage in the film tearing process of the glass is reduced; the reason is that the thermal conductivity of the nano graphene is as high as 5000W/mK, and the thermal conductivity of the thermal diffusion layer can be greatly increased by adding a very small amount of nano graphene, but because the thermal conductivity of the nano graphene is too high, how to disperse the nano graphene more uniformly is a key factor influencing the heat transfer uniformity of the heating plate, and the nano graphene is more uniformly dispersed in the thermal diffusion layer by virtue of the strong physical bonding force between the nano alumina and the nano graphene, so that the heat transfer uniformity of the heating plate is improved. On the contrary, the comparative examples 1 to 9 have low heat transfer efficiency, poor heat transfer uniformity, little temperature difference between the upper and lower surfaces of the heating plate, and low heat utilization rate, thereby causing energy waste.
More specifically, as can be seen from comparative examples 1 to 2, too much or too little polypropylene powder as a matrix of the heat diffusion layer affects the heat transfer efficiency and the heat transfer uniformity of the heating panel.
It can be seen from comparative examples 3-4 that when the amount of nano-alumina is too small, the nano-alumina is not enough to uniformly disperse the nano-graphene, thereby affecting the thermal conductivity and the heat transfer uniformity of the heating plate, and when the amount of nano-alumina is too large, the higher thermal conductivity of the nano-alumina itself also affects the thermal conductivity and the heat transfer uniformity of the heating plate.
As can be seen from comparative examples 5 to 6, nanographene, as a raw material component having high thermal conductivity, plays a key role in the thermal conductivity of the heating plate, thereby affecting the thermal conductivity and the heat transfer uniformity of the heating plate.
From the comparative examples 7 to 8, it can be seen that the substitution of nano-alumina with alumina and the substitution of nano-graphene with graphene play a key role in the heat transfer uniformity of the heating plate, thereby affecting the heat conductivity and the heat transfer uniformity of the heating plate.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
