Description
Technical field
The invention belongs to field of rubber technology, and in particular to a kind of promoter for binding cobalt salt based on palmitic acid cobalt and its
Preparation method.
Background technique
It is usually each by addition in rubber products industries such as radial wire cord tire, steel wire reinforcement conveyer belt, rubbers hose braided with steel wire
Class organic cobalt salt enhances performance with the bonding for improving rubber and metal.Cobalt salt significant proportion used in the country relies on import, state at present
It is certain poor that interior production cobalt salt chemical company exists between the external same industry in terms of technique, formula and stable product quality
Away from still having several drawbacks although having some patents in terms of promoter for binding cobalt salt.
Chinese patent (CN 101003641A) discloses a kind of formula and preparation method thereof of promoter for binding cobalt salt,
For promoter for binding cobalt salt the preparation method comprises the following steps: 31.54 parts by weight of cobalt hydroxide are added, 65 parts by weight of capric acid mix 10 weight of valeric acid
Part, 5 parts by weight of second propionic acid, 30 parts by weight of sec-octyl alcohol are mixed, stirring is warming up to 80-85 DEG C and reacts 2 hours, and then heating distillation is de-
Water and solvent are removed, last vacuum sloughs trace solvent and unreacted reactant, i.e. acquisition promoter for binding cobalt salt.The patent is with five kinds of acid
It instead of two or three of acid, forms the molecular structure in cobalt salt product network-like to wearing, improves the crosslinking in rubber product
The bonding force of steel wire in facilitation and merchant wire, but the fatty acid used in the patent is largely for capric acid, and capric acid
It is all kinds of organic acids to be extracted in petroleum as raw material preparation, thus the production cost of this cobalt salt is larger.
Common organic promoter for binding cobalt salt mainly includes cobaltous octadecanate, cobalt naphthenate, cobalt decanoate and cobalt boracylate,
Middle neodecanoic acid, aphthenic acids are substantially to be prepared using all kinds of organic acids extracted in petroleum as raw material, and belong to can not for petroleum
Regenerated resources, thus its price is more expensive, brings pressure to the production of cobalt salt to a certain extent；And domestic consumption market
Most of cobalt boracylate is by external import.In view of the above circumstances, it widens the new resources access of production organic cobalt salt and has become and work as
It is engaged in anxious.
Palmitic acid (also known as palmitinic acid), is a kind of saturated higher fatty acid, is widely present in nature, almost all of
All contain palmitin acid constituents in varying numbers in grease, in the seed of domestic economy crop Chinese tallow tree palmitic acid content up to 60%,
Palmitic acid content is a kind of reproducible environmentally protective resource up to 40% in the palm seed that the Southern Hemisphere is generally planted.Its point
Minor structure feature is the acid being connected with carboxyl (- COOH) with aliphatic group, and this point is identical as neodecanoic acid, stearic acid etc., equal energy
It is reacted with cobalt alkali and generates organic cobalt salt, this just provides possibility to substitute the synthetic fatty acid of this kind of valuableness.On the other hand, to the greatest extent
Pipe does not have also the related patents of palmitic acid cobalt to occur at present, but palmitic acid two methylene fewer than stearic acid, the fusing point of palmitic acid
Relatively low, the pure palmitic acid cobalt fusing point of synthesis is lower, and difficult forming, transportational process, use process are inconvenient.
Summary of the invention
