Description
Technical field
The invention belongs to interleaving agent manufacturing fields, relate in particular to a kind of vulcanization interleaving agent.
Background technique
During pneumatic tire vulcanization, curing bag is adhered with tire in order to prevent, is needed using with demoulding effect
Lubrication interleaving agent.This kind of interleaving agent is from materials such as initial soap powder, talcum powder, to silicone oil, the solution of silicon rubber, then arrives emulsification
The products such as silicone oil have already been through the development of decades.Currently, there are mainly three types of anti-sticking modes employed both at home and abroad: single to make
With bladder isolation agent, spray liniment collocation is used in spray liniment or bladder isolation agent and green tire in single use green tire.Wherein only
There is spray liniment in a few enterprise's single use green tire, and every tire will spray, usage amount is also very big；Some Enterprises
Still in such a way that spray liniment collocation uses in bladder isolation agent and green tire, but this mode is either artificial still in material
Waste is all bigger in terms of expense, and especially under present international situation, overseas market increases the tire anti-dumping power to China
Degree, until domestic tyre production enterprise is made to have to compress production cost in all its bearings, therefore, most enterprises are eliminated in green tire
Spray liniment, then use stripping result and all preferable bladder isolation agent class product of persistence.However as Tire production enterprise
Serialization, the automation of production process are required to be increasingly urgent to, the performance and operation mode of conventional capsule interleaving agent cannot expire
Foot needs, and not yet occurs the high performance interleaving agent of a new generation both at home and abroad and carrys out meet demand.
For these reasons, the present invention is prepared to lubricate between tire and curing bag using hydrogeneous silicone macromolecule and is isolated
Interleaving agent, be squeegeed onto inside green tire embryo, when vulcanization, the cross-linked polymer of generation can be shifted from tire liner surface
On to curing bag and can securely in conjunction with capsule surface, brush once can continuous several times demoulding, improve productivity.
Summary of the invention
For various deficiencies of the prior art, now disclose a kind of brushing once can continuous several times demoulding, improve productivity, prolong
In the long capsule service life, reduce tire production link, simplify production process, more conducively automation and quantity-produced vulcanization isolation
