Abstract

Provided are the use of TPE in an air filter fixing frame, a method of preparing TPE used in producing an air filter fixing frame, and a method of using TPE to produce an air filter fixing frame. Using TPE to produce an air filter fixing frame can give good elasticity to the air filter fixing frame and thus can make the coupling with a filter cartridge more secure, provide good sealing effects, and improve the service life of the air filter. Since the machining performance of TPE is good, using an insert moulding process together with the filter cartridge enables the air filter to be moulded as one piece, the complexity of controlling the process is low, the production efficiency of single product compared with an air filter produced using an adhesive pouring process is 10 times higher, and the aesthetic defects of the injection moulded product are few. Hence, production efficiency is greatly increased, energy consumption is greatly reduced, and the appearance of the products is smooth and attractive. Since TPE is non-toxic for the environment and can be recycled, the air filter fixing frame can be reused multiple times, reducing production costs and even scrap can also be degraded easily, significantly reducing pollution to the environment.

在该步骤中， 优选釆用嵌件成型工艺将空滤器固定框和滤芯一体成 型， 即在空滤器固定框模具内事先置入滤芯， 然后将熔融后的 TPE注射 入模具中，在滤芯周边成型出空滤器固定框，从而制得一体化的空滤器。 该方法可以使空滤器固定框与滤芯之间结合得更为紧密， 成型后的产品 只需经简单的外形修整即可得到表面平整无瑕疵的外观， 从而获得整体 结构更为稳固、 密封性能更好、 外观更为美观的空滤器； 同时嵌件成型 工艺较为成熟， 工艺控制难度低， 生产效率高， 成型后得到的已经是空 滤器产品， 无需再进行后续的空滤器固定框与滤芯的装配工序， 大大缩 短了生产周期， 减少了生产成本， 相比于 PU材质的空滤器固定框所釆 用的灌胶工艺， 其单个产品的生产效率可以提升 10倍以上。 In this step, it is preferable to integrally form the air filter fixing frame and the filter element by insert molding process, that is, insert the filter element in the air filter fixing frame mold, and then inject the molten TPE into the mold to form around the filter element. The filter frame is vented to produce an integrated air filter. The method can make the air filter fixing frame and the filter element more tightly combined, and the formed product can be obtained by a simple shape trimming to obtain a smooth and flawless appearance, thereby obtaining a more stable overall structure and better sealing performance. Good, more aesthetically pleasing air filter; At the same time, the insert molding process is relatively mature, the process control is difficult, the production efficiency is high, and the obtained after molding is already empty. The filter product eliminates the need for subsequent assembly steps of the air filter fixing frame and the filter element, which greatly shortens the production cycle and reduces the production cost. Compared with the glue filling process used in the PU filter box of the PU material, the single product The production efficiency can be increased by more than 10 times.
( 4 )冷却： 待模具冷却后， 打开模具， 取出注塑件， 即可得到空 滤器固定框。 对于釆用嵌件成型工艺一体成型的空滤器， 本步骤所得到 的注塑件为包括滤芯的空滤器固定框， 亦为空滤器。  (4) Cooling: After the mold is cooled, open the mold and take out the injection molded parts to obtain the air filter fixing frame. For the air filter integrally formed by the insert molding process, the injection molded part obtained in this step is an air filter fixing frame including a filter element, which is also an air filter.
本发明釆用 TPE来生产空滤器固定框，可以使空滤器固定框具备良 好的弹性， 因此可以与滤芯结合得更为紧密， 密封效果好， 提高了空滤 器的使用寿命； 由于 TPE的加工性能好， 与滤芯之间釆用嵌件成型工艺 即可一体成型出空滤器， 工艺控制难度低， 单个产品的生产效率较灌胶 工艺生产的空滤器提升 10倍以上， 且注塑成型的产品外观缺陷少， 因 此生产效率大为提高， 耗能大为降低， 产品外观平整美观； 由于 TPE环 保无毒且可以循环使用， 因此空滤器固定框可多次重复利用， 降低了生 产成本， 即使 ^艮废也易于降解， 大大减少了对环境的污染。  The invention uses TPE to produce the air filter fixing frame, so that the air filter fixing frame has good elasticity, so that the filter element can be more tightly combined, the sealing effect is good, and the service life of the air filter is improved; due to the processing performance of the TPE Well, the air filter can be integrally formed with the insert molding process, and the process control is difficult. The production efficiency of a single product is more than 10 times higher than that of the air filter produced by the glue filling process, and the appearance of the injection molded product is defective. Less, so the production efficiency is greatly improved, the energy consumption is greatly reduced, the appearance of the product is flat and beautiful; because the TPE is environmentally friendly and non-toxic and can be recycled, the air filter fixing frame can be reused many times, reducing the production cost, even if it is wasteful It is also easy to degrade and greatly reduces environmental pollution.
