Abstract
The present invention relates to a kind of Novel rubber antioxidant synthesis technologies, it includes mixing poly- butyl bis-phenol, terephthalic acid (TPA) zinc and silane coupling agent；Styrene is added and catalyst is reacted；Antioxidant is added and dispersing agent is reacted；By reactants separate.The present invention runs smoothly, the excellent product performance of manufacture.
Description
Technical field
The present invention relates to a kind of synthesis technologies of chemical products, and in particular to a kind of synthesis technology of rubber antioxidant.
Background technique
Currently, rubber product is in processing, storage, use process, due to by various factors, can it is gradually tacky, be hardened,
Embrittlement or cracking need to add certain anti-aging agent to extend its use value.The synthesis technology of most of rubber antioxidant
Generally existing operating cost is high, and whole not stable enough, not environmentally, performance is not ideal enough for the product of manufacture.
Summary of the invention
Goal of the invention: purpose of the invention is to overcome the shortcomings in the prior art, provides one kind and runs smoothly, manufacture
Excellent product performance Novel rubber antioxidant synthesis technology.
Technical solution: in order to solve the above-mentioned technical problem, a kind of Novel rubber antioxidant synthesis technology of the present invention,
It includes the following steps,
(1) poly- butyl bis-phenol, terephthalic acid (TPA) zinc and silane coupling agent are mixed at 60-70 DEG C according to 1:2:2, then passes to hydrogen
Gas；
(2) styrene and catalyst is added, is reacted between 90-105 DEG C, reaction pressure is in 7Mpa；
(3) antioxidant and dispersing agent is added, is reacted between 110-120 DEG C, reaction pressure is in 14Mpa；
(4) reactant is separated under 180-230 DEG C of 12Mpa high pressure hydrogen, temperature environment.
The utility model has the advantages that compared with prior art, the present invention its remarkable advantage is: the present invention by rigorous procedure of processing,
Ensure that overall operation is steadily reliable, the product service performance of manufacture is excellent, effectively improves product quality and economic benefit, simultaneously should
Product environmental protection, does not generate harmful substance.
Specific embodiment
Below with reference to embodiment, the present invention is further illustrated.
A kind of Novel rubber antioxidant synthesis technology of the present invention, it includes the following steps,
(1) poly- butyl bis-phenol, terephthalic acid (TPA) zinc and silane coupling agent are mixed at 66 DEG C according to 1:2:2, then passes to hydrogen；
(2) styrene and catalyst is added, is reacted between 98 DEG C, reaction pressure is in 7Mpa；
(3) antioxidant and dispersing agent is added, is reacted between 116 DEG C, reaction pressure is in 14Mpa；
(4) reactant is separated under 180-230 DEG C of 12Mpa high pressure hydrogen, temperature environment.
The present invention passes through rigorous procedure of processing, it is ensured that and overall operation is steadily reliable, and the product service performance of manufacture is excellent,
Product quality and economic benefit, while product environmental protection are effectively improved, harmful substance is not generated.
The present invention provides a kind of thinking and methods, and there are many method and the approach for implementing the technical solution, the above institute
Stating is only the preferred embodiment of the present invention, it is noted that for those skilled in the art, is not being departed from
Under the premise of the principle of the invention, several improvements and modifications can also be made, these improvements and modifications also should be regarded as guarantor of the invention
Range is protected, all undefined components in this embodiment can be implemented in the prior art.
