Description
Technical Field
The invention belongs to the technical field of polymer composite materials, and particularly relates to a preparation method of a high-temperature-resistant heat-conducting organic silicon composition.
Background
At present, the integration level and power of electronic components are higher and higher, the size is continuously reduced, and the overflow phenomenon of heat generated during the operation of the components is more serious, so that the temperature is increased rapidly, and the stability and the service life of the product are influenced. In order to solve the problem, the heat-conducting interface material is produced at the same time, and heat generated during the operation of the components is quickly transferred to the outside, so that the safe and stable operation of the electronic components is guaranteed.
The room temperature vulcanized silicone rubber system has excellent weather resistance and electrical insulation performance, is convenient to use, has no by-product and has extremely small shrinkage rate, thereby being widely applied to heat-conducting interface materials (such as heat-conducting pouring sealant, gaskets, extrusion glue and the like). Because the thermal conductivity of the room temperature vulcanized silicone rubber system is relatively low and is only 0.2W/(m.K), a large amount of heat-conducting powder is often required to be filled to improve the heat-conducting property of the material when the heat-conducting interface material is prepared, and the surfaces of the powder often have certain polar groups and are alkaline, so that silicone oil molecules are easier to oxidize at high temperature, and macroscopically, the problems of increased hardness and reduced toughness of the heat-conducting room temperature vulcanized silicone rubber system are shown, so that the stability of the heat-conducting effect of the heat-conducting room temperature vulcanized silicone rubber system is damaged.
At present, the silicone oil formula system can be improved to improve the high temperature resistance, for example, the invention patent of publication No. CN 109880545A introduces an epoxy resin system to effectively improve the heat resistance of the colloid, so that the high temperature resistant heat conductive adhesive tape prepared by the invention can work at a higher temperature for a long time, and the bonding performance is not obviously weakened. Secondly, the high temperature resistance of an organic silicon system is often improved by adding a heat-resistant auxiliary agent, for example, an organic silicon metal complex is added as the heat-resistant auxiliary agent in the patent of the invention with the publication number of CN 109535722A, so that the high temperature resistance is obviously improved, the prepared high temperature-resistant organic silicon material can be used at high temperature for a long time, the problems of cracking, pulverization and the like are avoided, and the long-term heat dissipation stability under the high temperature condition is effectively ensured; patent No. CN 103275491A discloses a silicone rubber heat-resistant additive, wherein the heat-resistant additive is prepared by reacting phosphate, borate, acetic acid ketone and the like at a certain molar ratio at 110-170 ℃ for 3-6 hours, the silicone rubber heat-resistant additive has good compatibility with silicone rubber and can also improve the maximum use temperature of the silicone rubber, but the heat-resistant additive has a complex formula and high manufacturing cost, and is not beneficial to popularization and application.
In conclusion, the invention adopts the cerium-zinc solid solution as the heat-resistant agent, provides the preparation method of the high-temperature-resistant heat-conducting organic silicon composition, and improves the stability of the room-temperature vulcanized silicone rubber system at high temperature so as to prolong the service life and widen the application range of the room-temperature vulcanized silicone rubber system.

Table 1: mechanical property test results before and after high-temperature aging of examples 1 to 3 and comparative examples 1 to 6
The mechanical property testing method comprises the following steps: testing the structural adhesive with tensile strength and elongation at break by referring to a GB/T1040.1-2006 method, and taking an average value for 3 times; the hardness is tested according to the method GB/T531-1999, and 3 times of average values are taken.
As can be seen from the data in the table, the mechanical properties after aging of examples 1, 2 and 3, in which the cerium-zinc solid solution is added as the heat-resistant agent, are very little changed compared with the blank control comparative examples 1, 3 and 5, respectively, which indicates that the cerium-zinc solid solution can effectively improve the high-temperature resistance of the heat-conductive silicone composition; in addition, as compared with comparative example 2 in which cerium-zinc solid solution is added as a heat-resistant agent, example 1 in which the hardness change is increased by only 4 and the hardness change is increased by 17 in comparison with comparative example 2 in which cerium oxide is added as a heat-resistant agent shows that the cerium-zinc solid solution has improved high-temperature resistance of the silicone composition as compared with cerium oxide, which is also demonstrated by the data of example 2 and comparative example 4, and example 3 and comparative example 6.
