[0007] CN 101074351A discloses a kind of hot-melt asphalt adhesive and its preparation method. This kind of asphalt adhesive is used for road surface hot-melt asphalt road stud adhesive, and many inorganic tackifiers are used, resulting in high kinematic viscosity. When sealed, inoperable
[0008] CN 10139A discloses an asphalt battery sealant and its preparation method. This sealant is made of three grades of asphalt and rosin, which meets the sealing requirements of ordinary batteries. However, the sealant is used for high-power and long-life batteries. When the ductility is poor, and can not meet the requirements of cold resistance, so it can not be borrowed
[0009] In addition, there are very few special asphalts for batteries on the market, and the performance varies greatly, which cannot meet the actual needs of new lead-acid batteries.

Embodiment 1

[0027] Embodiment 1: lead-acid battery asphalt sealant composition: the range of material selection is: composition comprises base material and crosslinking agent and flame retardant; Composition is calculated by weight, and wherein base material comprises: asphalt is 80~100 parts, 2-10 parts of SBS, 0.01-10 parts of tackifying resin, 0.01-20 parts of silica filler; 0.1-0.5 parts of sublimated sulfur as cross-linking agent; 0.1 part. The components of the lead-acid storage battery asphalt sealant in this embodiment are 100 parts of 70# asphalt, 7 parts of SBS, 10 parts of petroleum resin as a tackifying resin, 0.01 part of silicon oxide filler, 0.12 parts of sublimated sulfur as a crosslinking agent, and 0.12 parts of halogenated sulfur. The flame retardant is 0.05 parts of decabromodiphenyl ether

[0028] Select A-grade 70# road petroleum asphalt from China Petroleum and Chemical Corporation, and its performance indicators are shown in Table 2:

[0029] Table 2

[0030] ...

Embodiment 2

[0043] Embodiment 2: the difference of the lead-acid storage battery asphalt sealant of this embodiment and embodiment 1 is that the components are by weight, 60# asphalt is 80 parts, SBS is 10 parts, tackifying resin is petroleum resin 0.01 part, oxidized 20 parts of silicon filler, 0.1 part of sublimated sulfur as crosslinking agent, and 0.1 part of decabromodiphenyl ether as halogenated flame retardant.

[0044] The difference between the preparation method of the lead-acid battery asphalt sealant of this example and Example 1 is that in the steps: according to the components of this example, the base is added to the mixing reaction equipment in sequence, and the base material is heated to 100 ° C. The rotating speed is 7000 rpm, stirring for 30 minutes, and then under the same temperature condition, sublimated sulfur and decabromodiphenyl ether are added according to the ratio, and the stirring speed is continued to slow down for 4 hours, and the stirring speed is 800 rpm. ...

Embodiment 3

[0048] Embodiment 3: The difference of the lead-acid storage battery asphalt sealant of this embodiment and embodiment 1 is that the components are by weight, 70# asphalt is 90 parts, SBS is 2 parts, tackifying resin is 3 parts of petroleum resin, oxidized 15 parts of silicon filler, 0.5 part of sublimated sulfur as crosslinking agent, and 0.01 part of decabromodiphenyl ether as halogenated flame retardant.

[0049] The preparation method of the lead-acid battery asphalt sealant of this example is different from that of Example 1. In the steps: according to the components of this example, the base is added to the mixing reaction equipment in sequence, and the base material is heated to 160 ° C. The rotation speed is 8000 rpm, stirring for 1 hour, and then under the same temperature condition, sublimated sulfur and decabromodiphenyl ether are added according to the ratio, and the stirring speed is 800 rpm for 4 hours.
