The preparation method of the support pad 1 is as follows:
s11, placing the methyltrimethoxysilane, the organotin compound, the resin, the clay and the silicone oil into an internal mixer, and uniformly stirring for 5-10 minutes to ensure complete fusion;
s12, adding alkoxy-terminated polydimethylsiloxane and fumed silica into a power mixer, and stirring for 5-10 minutes under a vacuum condition to uniformly mix the materials;
s13, mixing the raw materials which are completely fused in the steps S11 and S12 again, entering an internal mixer for complete fusion, passing through an injection machine at the temperature of 100 ℃ and 200 ℃, and carrying out compression molding;
s14, after molding, vulcanizing again, heating to 250 ℃ for 2-5 hours.
Because add resin, clay in the supporting pad 1, can improve the viscidity in the supporting pad 1 to carry out softening treatment to supporting pad 1, make supporting pad 1 structure toughness strong, can the multi-angle bending, be convenient for laminate on skin, supporting pad 1 overall structure performance is soft on the side simultaneously, and the pjncture needle of being convenient for punctures.
Example 4
As a fourth embodiment of the present invention, in order to facilitate the hydrogel 4 to have good adhesiveness, the present inventors also provide a method for preparing the supporting pad 1, and as a preferred embodiment, the hydrogel 4 formulation includes hyaluronic acid, sodium alginate, chitosan, collagen, gelatin, and dextran.
Hydrogel 4 was prepared as follows:
s21, adding chitosan into water while stirring at room temperature, and performing ultrasonic treatment for 10 minutes to obtain a chitosan solution;
s22, at room temperature, slowly and uniformly adding sodium alginate into water, and uniformly stirring to obtain a sodium alginate solution;
s23, mixing the chitosan solution prepared in the steps S21 and S22 with the sodium alginate solution, adding collagen, gelatin and glucan while stirring, and uniformly mixing;
s24, smearing the solution prepared in the step S23 on hyaluronic acid gel, and airing.
Through the collagen and the gelatin that add, adhere on the hyaloplasm through the viscidity of self, be convenient for improve 4 holistic viscidity effects of aquogel, choose for use the hyaloplasm simultaneously for 4 whole printing opacity of aquogel are efficient, are convenient for paste 4 back of aquogel, the observation puncture point that can understand.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and the preferred embodiments of the present invention are described in the above embodiments and the description, and are not intended to limit the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
