Abstract

The invention discloses a sealing element of an asphalt battery, consisting of the following components (weight percentage): 45-55 percent of asphalt 10, 25-35 percent of asphalt 70, 5-15 percent of asphalt 100, 5-10 percent of rosin; a production method of the sealing element for the asphalt battery comprises the following steps: 1): raw materials are weighed according to a weight mixture ratio; 2): the rosin, the asphalt 10, the asphalt 70 and the asphalt 100 are mixed according to the weight mixture ratio an then heated to 250-260 DEG C and molten state; and 3): the material obtained in the step (2) is poured into a mold for cooling and molding. The product has high production efficiency, lower production cost than the normal sealing element, convenient storage and good sealing effect; in addition, when in use, the sealing element can be hot-melted on battery openings directly, thus effectively meeting the use requirement of people.

Description

A kind of asphalt battery sealing agent and preparation method thereof

Technical field

The present invention is a kind of asphalt battery sealing agent and preparation method thereof.

Background technology

Leakage is the big problem of one in the battery production, and the electric liquid of battery is mainly carbonates, like NSC 11801, methylcarbonate etc.Carbonates is stronger to organic dissolving power; Most polymers all can not be resisted its etch; And its viscosity and surface tension are all very low, very easily borrow wicking action along sealing part to exosmosis; Cause leakage, thus develop a kind of cost lower, deposit convenience, good sealing effect, battery sealing agent that production efficiency is high has been put on the people's work schedule.

Summary of the invention

In order to overcome the deficiency of prior art, the present invention provide a kind of cost lower, deposit convenience, good sealing effect, battery sealing agent that production efficiency is high.

The technical solution adopted for the present invention to solve the technical problems is:

A kind of asphalt battery sealing agent, its composition (weight %) is: No. 10 pitches: 45～55%, No. 70 pitches: 25～35%, No. 100 pitches: 5～15%, rosin: 5～10%.

A kind of making method of asphalt battery sealing agent:

1): take by weighing raw material according to weight proportion;

2): rosin and No. 10 pitches, No. 70 pitches, No. 100 pitch mixing post-heating are reached 250～260 ℃ to molten state according to weight proportion;

3): pour the material that step (2) obtains the moulding of into mould internal cooling.

The invention has the beneficial effects as follows: this production efficiency of products is high, and cost of manufacture is lower than general sealing compound, and deposit conveniently, good sealing effect, in addition, direct heat is melted at the battery opening part and is got final product during use, thereby effectively satisfies people's request for utilization.

Embodiment

A kind of making method of asphalt battery sealing agent:

1): take by weighing raw material according to weight proportion;

For ease of the present invention is further understood, combine specific embodiment to describe the present invention at present.

Embodiment 1:

1): take by weighing raw material according to weight proportion;

2): 10% rosin and No. 50%10 pitches, No. 30%70 pitches, No. 10%100 pitch mixing post-heating are reached 255 ℃ to molten state;

3): pour the material that step (2) obtains the moulding of into mould internal cooling; Conveniently stripped in order to guarantee, can in mould, put into an amount of talcum powder.

Embodiment 2:

1): take by weighing raw material according to weight proportion;

2): 5% rosin and No. 55%10 pitches, No. 35%70 pitches, No. 5%100 pitch mixing post-heating are reached 260 ℃ to molten state;

This product is compared with the product that embodiment 1 obtains: penetration number is less, stickiness is bigger, and ductility is less, and softening temperature is higher.

Embodiment 3:

1): take by weighing raw material according to weight proportion;

2): 10% rosin and No. 45%10 pitches, No. 30%70 pitches, No. 15%100 pitch mixing post-heating are reached 250 ℃ to molten state;

This product is compared with the product that embodiment 1 obtains: penetration number is big, stickiness is less, and ductility is bigger, and softening temperature is lower.

This production efficiency of products is high, and cost of manufacture is lower than general sealing compound, and deposit conveniently, good sealing effect, in addition, direct heat is melted at the battery opening part and is got final product during use, thereby effectively satisfies people's request for utilization.
