Description
Technical field
The present invention relates to rubber softening technical field, and in particular to a kind of solid tyre RX and preparation side
Method.
Background technology
RX is that rubber fabricates one of essential auxiliary agent, and its main function is rubber is divided greatly
Inter-chain action power is reduced, sizing material is easy to process and improves some performances of clothes material.RX mainly include by alkane,
The petroleum that cycloalkane, aromatic hydrocarbons are constituted；Include the mineral of the compositions such as coal tar, coumarone indene resin and coal tar pitch by coal coking
Oil system；The product obtained by plant pine tree, such as pine tar, rosin, the Pine plants oil system three major types of tall oil composition.Wherein
The poisonous and harmful problem of mineral coal tar system is larger, and usage amount is gradually decreased.Pine tar due to raw materials for production pine stump it is exhausted with
And the rise application amount of rosin price is less and less.Petroleum Production softening agent is that the rubber mainly applied in current rubber industry is soft
Agent, and it is the most commonly used with aromatic naphtha softening agent.Aromatic naphtha derives from the oil for non-renewable resources, in the long term resource
Also it is not rich.The particularly development of rubber industry in recent years, the environmental issue to rubber proposes higher requirement, wherein
The security of RX receives much attention.Traditional mainstay produces aromatic naphtha, has more carcinogenic to human body due to containing in base
Polycyclic aromatic hydrocarbon compounds, have not been met in European Union's REACH environmental laws regulation to rubber by the various rubbers of its production
The limits value requirement of middle polycyclic aromatic hydrocarbon content.
At present, environmentally friendly softening agent on the market is broadly divided into cyclohexanedicarboxyester ester series（Such as the carboxylic acid of hexamethylene -1,2
Ester）, vegetable oil series（Such as castor oil, epoxidized soybean oil）, polyol ester series（As fatty acid pentaerythritol ester, three acetic acid are sweet
Grease, diethylene glycol (DEG) ester）, epoxidized vegetable oil acid polyol ester and alkyl pyrrolidone etc..Using common environmental protection as softening agent,
Physical and mechanical properties is poor, it is impossible to meets some tires, the production requirement of sebific duct enterprise, therefore significantly limit answering for rubber
With market and value of the product.
Therefore, a kind of rubber that there is preferable rubber softening function, there is preferable safety in utilization again is researched and developed
It is significant with softening agent, the demand of existing market is also complied with, with preferable application prospect.
The content of the invention

8 ~ 15 parts of acetoacetic ester, 3 ~ 10 parts of citric acid.
Preferably, 35 parts of the naphthenic oil, 12 parts of paraffin, 15 parts of glycerine, 18 parts of vegetable and animals oils, 15 parts of natural shell, hard
9 parts of glycerol, 10 parts of ethyl acetate, 7 parts of citric acid.
Preferably, the vegetable and animals oils include soybean oil, rapeseed oil, linseed oil, palm oil, lard or butter.
Preferably, the natural shell includes peanut shell, sunflower seed shell or rapeseed hull.
The invention further relates to a kind of method for preparing solid tyre RX, comprise the following steps：
（1）Natural shell is weighed respectively according to proportioning, is crushed and is crossed 200 ~ 250 mesh sieves；
（2）Natural shell powder is placed in apparatus,Soxhlet's, 4 ~ 6h is extracted in the in the mixed solvent mixing of second alcohol and water, obtains
Extract solution, then concentrates extract solution, freezes, obtains natural fruit shell extract freeze-dried powder, standby；
（3）Vegetable and animals oils, natural shell are extracted freeze-dried powder and be placed in container respectively according to proportioning, 30 ~ 40 DEG C, mixing are warming up to
After stirring, naphthenic oil, paraffin and glycerine are added into mixture, is mixed evenly, then adding glycerol stearate
Ester, ethyl acetate and citric acid, stir 5 ~ 10min；
（4）By step（3）Obtained mixture is cooled to room temperature, then stands 5 ~ 10min, produces the solid tyre rubber
Softening agent.
Preferably, the step（2）The addition quality of the mixed solvent of middle ethanol and water is the 10 ~ 20 of natural fruit chitin amount
Times.
Preferably, the step（2）The mixed volume ratio of middle ethanol and water is 1:1~1.5
