全生物降解改性粒子TPEE的包胶方式是很多客户朋友都想弄清楚的,而关于它的信息介绍,自然是的厂家才清楚。我们快来一起具体看看吧。

Many customers and friends want to know the coating method of TPEE, but the information about TPEE is only clear to professional manufacturers. Let's have a concrete look together.
1.真包胶:TPEE与塑料、金属等材料通过化学作用在两种材料的键合界面形成牢固的焊接或键合作用,如分子渗透、极性基团的反应性连接和键合或类似的氢键,而没有任何机械和物理作用。无需粘合剂,可通过注塑直接与金属结合。
1. True coating: TPEE and plastics, metals and other materials form firm welding or bonding at the bonding interface of the two materials through chemical action, such as molecular penetration, reactive connection and bonding of polar groups or similar hydrogen bonding, without any mechanical and physical action. Without adhesive, it can be directly combined with metal through injection molding.

在这种加工方法中,TPEE和金属零件一般是整体包胶的,TPE的硬度尽可能高(70~80A及以上),这样可以达到一定的包胶效果,因为TPE和金属的包胶不具有真 正意义上的附着力(化学和分子水平),金属完全被TPE的强度所包胶。此外,金属零件表面有凹槽和孔(如螺母和刀柄)。
In this processing method, TPEE and metal parts are generally coated as a whole, and the hardness of TPE is as high as possible (70 ~ 80A and above), which can achieve a certain coating effect, because the coating of TPE and metal does not have the real adhesion (chemical and molecular level), and the metal is completely coated by the strength of TPE. In addition, there are grooves and holes on the surface of metal parts (such as nuts and tool handles).
2.假包胶:TPEE与硬质材料(塑料、金属或其他材料)纯靠孔洞、凹槽等卡扣方式进行物理机械结合,而不是单纯依靠两种材料的化学结合。两种材料的结合面没有分子水平的直接渗透,也没有极性基团或类似氢键的反应链接键(范德华力)。用粘合剂粘合。
2. False encapsulation: TPEE and hard materials (plastic, metal or other materials) are combined physically and mechanically only by the way of holes, grooves and other clasps, rather than simply relying on the chemical combination of the two materials. The interface between the two materials has no direct penetration at the molecular level, and there is no polar group or hydrogen bond (van der Waals force). Bond with adhesive.
有时候对于一些特殊产品,橡胶只是部分覆盖了金属零件的相应位置,不利于TPEE与金属零件的牢固结合。在需要涂覆的金属表面涂覆一层粘合剂是一种常见的想法。但实际上,由于TPEE与橡胶的成型工艺不同,对橡胶零件与金属零件的粘接牢固度有重要影响。胶粘剂类型的选择对于这类金属制品的涂装至关重要。
Sometimes for some special products, rubber only partially covers the corresponding position of metal parts, which is not conducive to the solid combination of TPEE and metal parts. It is a common idea to apply a layer of adhesive to the metal surface to be coated. But in fact, due to the different molding process between TPEE and rubber, it has an important impact on the bonding strength between rubber parts and metal parts. The choice of adhesive type is very important for the coating of this kind of metal products.
3.整体包胶
3. Whole package
整体包胶相当于注塑一个TPEE塑料件,其中硬件产品是包胶的,没有化学键合,所以包胶还是可行的。一般硬度较高的TPEE,硬度在80A以上的都可以包胶,但是包胶的五金件要整体镀膜,如果只镀膜一部分很难实现。
The whole package is equivalent to injection molding a TPEE plastic part, in which the hardware product is coated without chemical bonding, so the package is still feasible. Generally, TPEE with higher hardness and hardness above 80A can be coated with glue, but the coated hardware should be coated as a whole, and it is difficult to achieve if only a part of the coating is coated.
