Problems solved by technology

Chinese patent CN100480333C and U.S. patents US3032531, US3876605, US5196228A, etc. all use phenyl silicone rubber as raw rubber to prepare rubber with radiation resistance, which really improves the radiation resistance of silicone rubber, and its radiation resistance can reach 5× 10 8 Lun or so, but in the face of today's higher radiation resistance performance requirements, they are already incompetent

Embodiment Construction

[0028] Below in conjunction with embodiment technical scheme of the present invention is described in further detail:

[0029] The steps of the preparation method of the silazane damping agent containing triphenylsiloxane structure are:

[0030] (1) Preparation for synthesis

[0031] Molecular sieves are dried in a box-type resistance furnace at 400°C for 3.0 hours, put into a desiccator to cool, then put dry molecular sieves into a container containing toluene, and place them for more than 2 days before use; the glass instruments and stirring After the rod is cleaned, put it into the oven, set the temperature of the oven at 120°C, bake for 2 hours, and wait for use after cooling. The glass instrument includes a four-necked reaction bottle, an air guide tube, a reflux condenser, and a constant pressure dripping device.

[0032] (2) intermediate synthesis reaction

[0033] Install a stirring device at the middle port of the four-necked reaction bottle, install an air guide pi...

Abstract

The invention provides a radiation-resistant additive and synthesis thereof, and a method for preparing a radiation-resistant silicone rubber material, wherein the structure formula of the radiation-resistant additive is as follows, and mixing vulcanizing is performed by using the radiation-resistant additive as a radiation-resistant additive, using phenyl silicone rubber as a base rubber and adding a reinforcement agent, a structure control agent and a vulcanizing agent to prepare the radiation-resistant silicone rubber material. According to the present invention, the prepared radiation-resistant silicone rubber material has good radiation resistance, can be used for producing various kinds of rubber products such as electric wires, cable sheaths, rubber gaskets, sealing parts, member sheets and the like in various irradiation occasions, and can be widely used in aerospace, nuclear industry, electronic communications, chemical industry, medicine, marine and other fields requiring high-energy radiation.

Description

technical field [0001] The invention belongs to the technical field of special rubber functional materials and their production, and relates to a radiation-resistant additive containing a polyphenylsilazane structure, a synthesis method thereof, and a preparation method for preparing radiation-resistant silicone rubber materials. Background technique [0002] Since the oil crisis, countries around the world have generally attached importance to the development and utilization of energy, and people have been working hard to find energy that can replace oil. Therefore, nuclear power, as a safe, clean and reliable energy source, has been paid more and more attention to its development and utilization. In order to ensure the safety of nuclear power equipment, a large number of polymer elastomer sealing materials are used in electrical instruments, wire and cable insulation materials, gasket seals, etc. in the equipment. This type of sealing material not only needs to have suffi...
