| Polystyrene fiber | 403 | 11.5 | No corrosion and dissolution |
| Acrylic fiber | 415 | 9.9 | No corrosion and dissolution |
| Polyacrylonitrile fiber | 236 | 5.1 | Slight corrosion phenomenon |
| Polyamide fibers | 247 | 4.7 | Slight corrosion phenomenon |
| Polyethylene fiber | 437 | 12.7 | No corrosion and dissolution |
| Wood fiber | 421 | 10.3 | No corrosion and dissolution |
| Polyester fiber | 451 | 13.8 | No corrosion and dissolution |
As can be seen from table 1, the cotton core material which has good compatibility with the primer and no corrosion or dissolution phenomenon is suitable for preparing the primer pen, and the cotton core material comprises acrylic fibers, polystyrene fibers, polyethylene fibers, wood fibers and polyester fibers, wherein the cotton core material has the best adsorption performance on the primer, and the cotton core material with the highest adsorption rate and adsorption rate is the polyester fibers, so that the cotton core material prepared from the polyester fibers is the best choice.
The pen core of the primer needs to be made of high-density fiber materials, and a large number of gaps are filled. From the experimental results in table 1, the adsorbability of the refill prepared from the above materials to a primer, the drinking time, the writing stability, the service life and the compatibility are considered, and acrylic fibers, polystyrene fibers, polyethylene fibers, wood fibers or polyester fibers and the like are selected for preparing the refill, wherein the refill has the best adsorbability to the primer, and the polyester fibers have the highest adsorbability and adsorption rate. Meanwhile, the primer needs to be led out of the cotton core, so that the absorption performance of the material of the pen core and the material of the cotton core to the primer is required to be similar. Therefore, when in use, the primer seeps out of the cotton core to the pen core under the action of gravity as the pen core is contacted with the cotton core; when the use is stopped, the primer can be returned to the cotton core from the pen core. Therefore, the use of polyester fibers for the preparation of the refill of the primer pen is also the best choice.

As can be seen from table 1, 8 materials of polystyrene, ABS plastic, polypropylene, polyvinyl chloride, polyester, polyacrylonitrile, polyamide and polyethylene can basically meet the material requirement of the rubber ring, wherein polystyrene, polyvinyl chloride, polyester, polyamide and polyethylene are more preferable from the viewpoints of airtightness and compatibility with the primer and fixation of the pen core and the pen point, and the rubber ring made of polyethylene has the best airtightness, the mass loss rate of only 10.0%, and the rigidity and elasticity are more suitable, so the material of the rubber ring is most preferably polyethylene.
Example 4 air tightness test
The air tightness of the primer pen has a decisive influence on the practicality and the service life of the product. The primer is generally a volatile substance with a low boiling point, and the substance is very easy to volatilize at normal temperature. The product inevitably generates a high-temperature environment (more than or equal to 35 ℃) in the processes of storage, transportation and vending; if the air tightness is not good, the primer can be volatilized rapidly, thereby affecting the performance and the service life of the product.
In order to ensure the best performance of the product, the research group has conducted a lot of material selection and tests for this problem. By adopting the portable primer pen provided by the embodiment 1, the cotton core and the pen core are made of polyester fiber, the rubber ring is made of polyethylene, and the pen point and the pen cap are made of ABS (acrylonitrile butadiene styrene), the portable primer pen can be maintained for 28 days by a research group in an environment of 60 ℃ and 25 ℃ respectively; the results showed that the amount of primer lost was 10% and 1%, respectively.
The compatibility of the package with the primer is also a very critical factor, during the above air tightness test. We did not find any adverse effect of the primer on the packaging material. The primer properties did not change, nor did the packaging change.
Although the present invention is disclosed above, the present invention is not limited thereto. Various changes and modifications may be effected therein by one of ordinary skill in the pertinent art without departing from the scope or spirit of the present invention, and the scope of the present invention is defined by the appended claims.
