Embodiment 1

[0012] A transformer oil storage capsule, which is prepared according to the following method:

[0013] 1) Preparation of colloid: under normal temperature and pressure, 100 parts of polyvinyl chloride and 30 parts of polypropylene are mixed and mixed, and 3 parts of silicon carbide and 2 parts of aluminum oxide are added to the open mill. 1 part of sodium alginate, mixed evenly to form a colloid;

[0014] 3) Preparation of auxiliary materials: mix molybdenum disulfide, talc powder and barium sulfate according to the mass ratio of 2:1:1, and stir evenly to obtain the product;

[0015] 3) Preparation of adhesive plaster: Add ethyl acetate and auxiliary materials to the colloid in step 1), and stir evenly to form a glue; at 45°C and under normal pressure, put the glass fiber fabric on a glue spreader, and coat the above glue into a glue Adhesive plaster; dry it, and get it immediately; wherein, the mass ratio of colloid, ethyl acetate and auxiliary materials is 10:2:1.

Description

technical field [0001] The invention belongs to the field of electric power materials, and in particular relates to a production method of transformer oil storage capsule rubber. Background technique [0002] The oil conservator is one of the main components of the transformer. Its function is to compensate the volume expansion or contraction of the insulating oil due to temperature changes, so as to ensure that the oil-filled equipment is always filled with oil. The common oil conservator has three types: open type, capsule type or diaphragm type and bellows type. Capsule oil conservator is a tight capsule that can withstand high pressure installed in the oil conservator. The insulating oil is separated from the outside air through the capsule, and the moisture absorber prevents water vapor from entering the capsule. During operation, the capsule floats On the oil surface, inhale or exhaust as the oil level rises or falls, so as to automatically balance the pressure on bot...
