PU synthetic leather is how to develop
and progress? In addition to the production process, equipment, substrate and
other continuous innovation, perhaps more important is the development of
additives, innovation.
The additives mentioned in this article
include not only the additives and functional materials, but also the surface
treatment agents, special resins and the like which are prepared by blending or
synthesizing the additives and the functional materials with ordinary PU resin.
Its use includes PU resin additives and PU synthetic leather additives.
In general, PU synthetic leather innovation
as follows:
Innovative additives to the process of PU
synthesis = PU resin -> + innovative innovative additives such as the base
fabric + filler + Toner -> by a variety of innovative manufacturing process
= PU synthetic leather.
Thus, the development of additives in the
development of PU synthetic leather plays a vital role.
Additives classification: Additives are
generally divided into the following five categories:
First, solve the fault class. Such as:
defoamer, wetting agent, anti-pin agent, leveling agent, wet with fixing agent,
removal of DMF additives, even foam additives, anti-adhesive, interfacial
fusion agent, tackifier, dispersant and many more. This kind of material in the
PU resin and PU synthetic leather manufacturing process plays a vital role,
without them, PU resin and PU synthetic leather can not be normal production.
