Comparative example 3: the procedure is identical to example 1, except that the vulcanization temperature is 140 ℃ and the vulcanization time is 4 min.
The mechanical properties of inventive examples 1-7 and comparative examples 1-3 are shown in Table 1.
As shown in Table 1, the tear strength and tensile strength of examples 1 to 7 were 45KN/m or more and 9MPa or more, respectively, and they had high mechanical strength. It can be seen from examples 1-3 that the enhancement of the mechanical properties of the silicone rubber by the hyperbranched POSS is mainly determined by the vinyl density and the total content, and the mechanical properties of the silicone rubber are gradually enhanced with the gradual increase of the vinyl density and the total content in examples 3, 1 and 2. From examples 1, 4 and 5, it can be seen that the mechanical properties of the silicone rubber are related to the total active hydrogen content of the hydrogen-containing silicone oil and the addition amount of the platinum catalyst, and that the higher the total active hydrogen content of the hydrogen-containing silicone oil is, the stronger the mechanical properties of the silicone rubber are, and the higher the addition amount of the platinum catalyst is, the stronger the mechanical properties of the silicone rubber are. It can be seen from examples 1, 6 and 7 that the mechanical properties of the silicone rubber are related to the temperature and time of the vulcanization process, and when the temperature is low and the vulcanization time is short, the mechanical properties of the silicone rubber are weak without complete vulcanization, while when the vulcanization of the silicone rubber is complete, the mechanical properties of the silicone rubber are less affected by the vulcanization temperature and the vulcanization time. It is clear from examples 1, 8 and 9 that the mechanical properties of the silicone rubber increased and then decreased with increasing amounts of hyperbranched POSS added.
Compared with the examples 1-7, the hyperbranched POSS of the comparative example 1 is only added by 0.0001g, and the hyperbranched POSS has a reinforcing effect on the silicon rubber and plays roles in physical winding centralized crosslinking and chemical centralized crosslinking, so that the tensile strength and the tear strength are lower; comparative example 2 only added 1g active hydrogen content for 0.5% hydrogen silicone oil and 1g platinum catalyst, when its vulcanization, was not completely vulcanized, which shows that the hydrogen silicone oil and platinum catalyst need to reach a certain amount to make silicone rubber achieve the vulcanization purpose. In comparative example 3, vulcanization conditions of 140 ℃ and 4min were adopted, and the obtained vulcanizate had poor properties because under the vulcanization conditions, the silicone rubber was not completely vulcanized.
The safety tests of examples 1 to 7 of the present invention and comparative examples 1 to 3 are shown in Table 2.
As can be seen from Table 2, the cytotoxicity tests, delayed type hypersensitivity and intradermal stimulation tests of examples 1-7 and comparative examples 1-3 are all qualified, which indicates that the high mechanical medical silicone rubber of the present invention has better biocompatibility. And even if the silicon rubber is not completely vulcanized, the biocompatibility of the silicon rubber is not influenced.
In conclusion, the high-mechanical-property medical silicon rubber prepared by the invention not only has good mechanical property, but also has the characteristics of no toxicity, no stimulation and high safety to organisms.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the description as long as there is no contradiction between the combinations of the technical features.
