Features and applications oxidation, esterification, saponification of polyethylene wax powder

For the success of the polyethylene wax for aqueous paints and aqueous inks, often oxidized polyethylene wax, having a carboxyl group and a polar group to group. However, the oxidation process also makes polyethylene wax degradation, chain scission reduces the degree of crystallinity, its performance is dropping lower melting point, hardness decreased. This reduces the effect as a wax: anti-adhesion, smoothness, abrasion.
The oxidized polyethylene wax with two or more monovalent or divalent metal ion Mx, such as calcium, magnesium, aluminum, cerium, other appropriate cross-linking:
We want to get both hydrophilic and  Stabilizers for pipe smooth, abrasion resistance.
Dispersing method: deionized water, a surfactant, heated to boiling, to be emulsified into the wax powder, under strong stirring and then rapidly cooling to room temperature, adjusted with ammonia Ph value between 7-8. The wax dispersion can be easily dispersed in an aqueous ink, without precipitation, without float.
Saponification wax powder is also good to use as emulsifier effect of ammonium perfluorooctanoate and physical contact.
Two
Micronized wax aqueous dispersion for waterborne coatings, water-based inks, textile finishing, leather modifications and other fields.
Application of results:
1, extinction, antiblocking
Especially the oxidized polyethylene wax powder Mx saponified aqueous polyethylene wax dispersion for paints and inks have a significant effect extinction. 2-5% of the amount of film 60 ° gloss reduction of 20%. Smooth, anti-adhesion effect is obvious.
2, wear
Saponified polyethylene wax after partial crosslinking, molecular weight, crystallinity, improved hardness, lubricity both, but the end of the dynamic coefficient of friction coating to  zinc stearate reduce anti-friction capacity doubled.
3, feel
The coating soft touch, smooth and comfortable.
4, anti-aging and promote the solidification
Saponification wax coating can absorb calcium aging free radicals, from delaying the effects of aging coating.
Cerium has a variable coordination number  Azodicarbonamide and the remaining valence, because the 4f orbitals, located 6s, 5p, 5d inner orbit, its bonding capacity is weak, it is characterized by pro-dry agent of this nature in the cured coating from the promotion of cross-linking process and accelerate the curing effect.
