FAQ: How to solve the rubber spray (whitening) problem?
Rubber has unvulcanized rubber (hereinafter referred to
as rubber) and vulcanized rubber (hereinafter referred to
as products), rubber frost spray including rubber surface
spray and product surface spray. Frost spray (BLOOM) is
the phenomenon that liquid or solid complexes migrate
from the rubber interior to the rubber surface [1].
Visible rubber internal coordination agent precipitation,
the formation of frost spray. The form of rubber spray
frost summed up, roughly divided into three kinds. Namely
spray powder, spray wax, spray oil (also known as
exudation). Powder spray is vulcanizing agent, promoter,
active agent, anti-aging agent, filler and other powder
complexes precipitated on the rubber surface, and form a
layer of powder. Spray wax is paraffin, ground wax and
other wax precipitated on the rubber surface, and form a
layer of wax film. Oil injection is the softener,
viscosifier, lubricant, plasticizer and other liquid
complexes precipitated on the rubber surface, and the
formation of a layer of oil.
In practice, the surface of rubber products in the form
of frost spray sometimes in one form, sometimes in two or
three forms at the same time.
In a recent period of time, spray frost phenomenon has
been a headache, ejecta zinc stearate, white carbon
black, calcium carbonate, anti-aging agents, promoting
agents and so on, from which I checked some information,
sent to you, some of the paper may have been sent in this
forum, so please understand
Regarding frost spraying, the following points need to be
paid attention to:
1. Appropriately increase the amount of synthetic glue,
which is helpful to reduce the ejection of filler
2. The use of a variety of promoters and reduce the
supersaturation of promoters
3. USES the many kinds of stabilizer and because work
need its migration, antiager itself if but with one or
the dosage is too large, will inevitably lead to the
rapid, with other substances, so employ, can reduce the
dosage of single protective agent, on the one hand, can
reduce the supersaturated danger, on the other hand can
also extend the action time of protective agent
4. Appropriately increase the dosage of solid softener to
adsorb filler
5. If zinc stearate is used as isolating agent, the
return wire must be tempered evenly to prevent local
saturation of zinc stearate and ejecting
The frosting on the rubber surface not only affects the
appearance quality and service life of the products, but
also affects the processing performance and technological
performance of the semi-finished products of the rubber
material. At the same time, it also causes certain
economic losses to the enterprise and brings immeasurable
damage to the reputation of the enterprise. Therefore,
formula designers, process formulation personnel in the
design of the formula, formulation of the process should
fully consider the characteristics of raw rubber, the
performance and dosage of the agent, the factory's
processing conditions, storage environment, product
storage cycle, use conditions and so on; Production
operators must operate in accordance with the process
procedures; The purchasing personnel should be organized
according to the material origin and standard required by
the formula design, so that the various properties of
rubber can reach or close to the level of the formula
design, in order to avoid the occurrence of quality
problems such as rubber spray frost.
