Embodiment 1

[0012] A method for preparing a battery sealant of the present invention comprises the following steps: 1) heating 45 parts by weight of asphalt at 150°C for 2 hours, adding 10 parts by weight of modified epoxy resin, 10 parts by weight of nonyl Phenol polyoxyethylene ether and 1 weight part of fumed silica were stirred evenly to obtain a crude product; 2) when the temperature of the crude product obtained in step 1) was cooled to 80°C, 10 weight parts of gasoline and 10 Aromatic oil in parts by weight is uniformly stirred, filtered and packaged to obtain the product.

Embodiment 2

[0014] A method for preparing a battery sealant of the present invention comprises the following steps: 1) heating 50 parts by weight of asphalt at 180°C for 3.5 hours, adding 15 parts by weight of modified epoxy resin, 15 parts by weight of nonyl phenol polyoxyethylene ether and 3 parts by weight of fumed silica, and stir evenly to obtain a crude product; 2) when the temperature of the crude product obtained in step 1) is cooled to 100°C, add 15 parts by weight of gasoline and 15 parts by weight of aromatic oil, stirred evenly, filtered and packaged to obtain the product.

Embodiment 3

[0016] A method for preparing a battery sealant of the present invention comprises the following steps: 1) heating 55 parts by weight of asphalt at 200°C for 5 hours, adding 20 parts by weight of modified epoxy resin, 20 parts by weight of nonyl Phenol polyoxyethylene ether and 5 parts by weight of fumed silica were stirred evenly to obtain a crude product; 2) when the temperature of the crude product obtained in step 1) was cooled to 120°C, 20 parts by weight of gasoline and 20 Aromatic oil in parts by weight is uniformly stirred, filtered and packaged to obtain the product.

[0017] The performance of the three battery sealants obtained in Examples 1 to 3 and a commercially available battery sealant were tested with reference to the relevant test methods of the battery sealant SH / T0421-92 petrochemical industry standard. The test results are shown in the table 1; as can be seen from Table 1, battery sealant of the present invention has all reached the requirement of index in...

Abstract

The invention discloses a sealing compound for batteries and a preparation method of the ealing compound and belongs to the technical field of battery sealing materials. The sealing compound for the batteries, disclosed by the invention, contains the following raw materials in parts by weight: 10-20 parts of gasoline, 10-20 parts of aromatic hydrocarbon oil, 45-55 parts of asphalt, 10-20 parts of nonylphenol polyoxyethylene ether, 10-20 parts of modified epoxy resin and 1-5 parts of aerosil. The invention also provides the preparation method of the sealing compound for the batteries. The sealing compound for the batteries, disclosed by the invention, has very good adhesion property, sealing property and creep resistance, also has good aging resistance, high-temperature stability and temperature sensitivity and is specifically manifested as that the sealing compound does not deform and does not flow at high temperature, has good adhesion property and does not crack at low temperature, is easy to paint, is odorless and is long in service life.

Description

technical field [0001] The invention belongs to the technical field of battery sealing materials, in particular to a sealing glue for batteries and a preparation method thereof. Background technique [0002] With the advancement of science and technology and the rapid development of information, people's fast-paced production and life are increasingly inseparable from batteries. Although, from the date of its birth, the battery has undergone continuous changes and changes. However, zinc-manganese batteries are the most widely used. The main components of the electrolyte of zinc-manganese batteries are ammonium chloride, zinc chloride and water in a certain proportion. If the sealing performance of the battery is not good, the water in the electrolyte will volatilize and affect the normal operation of the battery; the oxygen in the air will also enter the inside of the battery to oxidize the zinc and reduce the service life of the battery. It can be seen that the seal plays...
