preparation example 1

[0080] The following parts by mass of raw materials are needed to prepare 1 kg of self-healing fiber:

[0081] Polyacrylonitrile 0.48kg;

[0082] Polyvinylpyrrolidone 0.12kg;

[0083] Dicyclopentadiene 0.4kg.

[0084] The preparation process of self-repairing fiber includes the following process steps:

[0085] Step 1, spinning, put polyacrylonitrile and polyvinylpyrrolidone into DMF to dissolve completely, configure the spinning solution with a concentration of 14wt% for spinning, the diameter of the spinneret hole on the spinneret plate is 50 μm, and the diameter of the spinneret hole The diameter of the inlet pipe was 30 μm, and a hollow fiber with an outer diameter of 50 μm and an inner diameter of 30 μm was obtained.

[0086] Step 2, passing through a water bath, that is, passing the hollow fiber obtained in step 1 through a water bath, the temperature of the water bath is 60° C., and the time of the water bath is 30 minutes, and then taken out and dried at 60° C. for ...

preparation example 2

[0090] The difference between Preparation Example 2 and Preparation Example 1 is that step 2 adopts the treatment method of alkali reduction instead of the treatment method of water bath, and the specific steps are as follows,

[0091] Step 2, alkali reduction treatment, that is, put the hollow fiber obtained in step 1 into a 10wt% concentration of sodium hydroxide solution, the treatment time is 10 minutes, and the treatment temperature is 90 ° C. After the treatment is completed, take it out, wash and dry it, and the porous fiber .

preparation example 3

[0093] The difference between Preparation Example 3 and Preparation Example 2 is that the following parts by mass of raw materials are required to prepare 1 kg of self-repairing fiber:

[0094] Polyacrylonitrile 0.6kg;

[0095] Polyvinylpyrrolidone 0.1kg;

[0096] Dicyclopentadiene 0.3kg.

[0097] In step 1, the diameter of the spinneret hole on the spinneret is 40 μm, and the diameter of the inlet tube is 20 μm, to obtain a hollow fiber with an outer diameter of 40 μm and an inner diameter of 20 μm.

[0098] In step 4, the impregnated fibers obtained in step 3 are cut into fibers with a length of 0.9 mm to obtain self-repairing fibers.

Abstract

The invention relates to a rubber sealing valve, and belongs to the technical field of rubber sealing parts. The rubber sealing valve comprises a metal valve, an organic silicon adhesive and a sealing ring; the sealing ring is adhered to the metal valve through the organic silicon adhesive, and the sealing ring at least comprises the following raw materials by mass: 30-40 parts of a filler; 2-3 parts of zinc oxide; 6-12 parts of a functional auxiliary agent; 0.5-1 part of a vulcanizing aid; 1-2 parts of a peroxide vulcanizing agent; and 45-55 parts of ethylene propylene diene monomer raw rubber. The metal adhesive has the effects that the bonding strength between the metal adhesive and the rubber sealing ring is improved, so that secondary gluing is simplified into primary gluing, and the production efficiency is improved.

Description

technical field [0001] The present application relates to the field of rubber seals, in particular to a rubber seal valve and its production process. Background technique [0002] The electronic thermostat is an important part of the engine. Its function is to automatically adjust the amount of water entering the radiator according to the temperature of the cooling water, change the water circulation range, and adjust the heat dissipation capacity of the cooling system to ensure that the engine is within a suitable temperature range. Work. [0003] The electronic thermostat must be kept in good condition, otherwise it will seriously affect the normal operation of the engine. If the main valve of the electronic thermostat is opened too late, it will cause the engine to overheat; if the main valve is opened too early, the engine warm-up time will be prolonged and the engine temperature will be too low. At this time, it can be judged whether the working condition of the elect...
