preparation example Construction

[0032] The preparation method of special sealing wax of the present invention comprises following concrete steps (as figure 1 shown):

[0033] Step 1 (i.e. the first stage), put paraffin wax and polyethylene wax in the first blending kettle according to the ratio of the above raw materials, stir and heat, at 130°C, the stirring speed is 70 rpm, and mix for 1 hour to obtain the first stage mixture ;

[0034] Step 2 (that is, the second stage), stir and heat the microcrystalline wax and beeswax in the second blending kettle according to the above raw material ratio, at 100°C, the stirring speed is 50 rpm, and mix for 0.5h to obtain the second stage mixture ;

[0035] Step 3 (that is, the third section), add the first-stage mixture obtained in step 1 and the second-stage mixture obtained in step 2 into the third blending tank and stir and heat, at 120°C, the stirring speed is 60- 70 revs / min, mix 1h, obtain the third stage mixture;

[0036] Step 4 (that is, the fourth stage)...

Embodiment 2-3 and comparative example 4-8

[0046] Using the four-stage processing technology of the present invention, the sealing wax is prepared by feeding according to the ratio in Table 3, and the performance test is carried out.

[0047] Table 3: Feeding situation and performance test of embodiment 2-3 and comparative example 4-8

[0048]

[0049] In some embodiments of the present invention, it is shown that the addition amount of polyethylene wax has a certain relationship with the melting point of the sealing wax product: when the addition amount is at 1-3%, the melting point rises faster, and when the addition amount is at 3-4% When the melting point rises relatively steadily, when the addition amount is 5-5.5%, the melting point can meet the requirements. But when the addition amount exceeds 5.5%, the melting point shows a downward trend.

[0050] In some embodiments of the present invention, experiments have shown that low molecular weight polyethylene wax should be selected to avoid wax cracking in low te...

Abstract

The invention discloses a special-type sealing wax which comprises the following raw materials in percentage by weight: 73-80.5% of high-meltiong-point paraffin, 10-14.5% of high-melting-point microcrystalline wax, 4-6% of beeswax, 5-5.5% of polyethylene wax and 0.5-1% of tackifier. The preparation method has the advantages of high safety, environmental protection and low energy consumption; and the special-type sealing wax disclosed by the invention has the advantages of cheap and accessible raw materials and high product quality, can satisfy the requirements for sealing waxes in dry batteries as well as special-type waxes for fiber communication cables and oil transport pipeline sealing hot-melt adhesive tapes, and has wide application prospects.

Description

technical field [0001] The invention relates to a wax composition, in particular to a new type of special sealing wax, which belongs to industrial special waxes. Background technique [0002] The quality of the sealing wax used in dry batteries is related to the service life of the batteries. Japan's Matsushita Battery Co., Ltd. has strict requirements on the quality of sealing wax. The company has tried a variety of special waxes in my country, which is reflected in the moisture resistance, melting point, penetration and shrinkage at low temperatures. , especially in a certain humidity environment, the insulation and open time performance cannot meet the specified requirements. Japan's Matsushita Battery Industry Co., Ltd. originally mainly used the special wax-602 special wax of Nippon Jingwa Company and Mopido Company. But these specialty waxes are expensive. [0003] High-quality special wax is also required in optical fiber communication cables and sealing hot-melt ta...
