Description

A kind of particle anti-aging agent and preparation method thereof

Technical field

The present invention relates to polymeric material field, be specifically related to a kind of particle anti-aging agent and preparation method thereof.

Background technology

Rubber item is in long-term storage and use procedure, be subject to heat, ozone, variable valency metal anti-aging agent ion, mechanical stress, illumination, and can chap gradually when the erosion action of chemical substance, be clamminess or the catabiosis such as hardening embrittlement, prior art is the anti-aging agent that has added powdery in the raw material of preparing the rubber items such as rubber tyre for this reason, to improve the anti ageing property of rubber, but powdery anti-aging agent easily disorderly flies in processing and concrete application process, powdery anti-aging agent fills the air and in air, not only affects Working environment, be difficult to cleaning, and skin and respiratory tract to human body causes stimulation, each pipeline place that the powdery anti-aging agent that flies up of getting off for a long time deposits and is bonded on production line also can result in blockage, make troubles to enterprise.

Summary of the invention

Primary and foremost purpose of the present invention is to provide a kind of easy to use, particle anti-aging agent that anti ageing property is good.

For achieving the above object, the present invention has adopted following technical scheme: a kind of particle anti-aging agent is to be made by the raw material mixing granulation of following parts by weight: antioxidant BLE is 20～50, carrier 30 as one kind～50, tackiness agent 15～30; Described carrier is one or more in white carbon black, light calcium carbonate, wollastonite powder, ground silica, talcum powder and potter's clay; Described tackiness agent is one or more in Wax-for preventing rubber, Microcrystalline Wax, polyethylene wax, resin, pitch, rosin and tar, described pitch, the softening temperature of rosin are 80～120 DEG C, the softening temperature difference of different pitches, rosin is larger, be low to moderate 30 DEG C, up to 180 DEG C, for the preparation of particle anti-aging agent, need to select the pitch, rosin of suitable softening temperature as tackiness agent, when too low, rubber item easily melted in summer, when too high tackiness agent be difficult to melt mix with antioxidant BLE, and the rubber item elasticity of preparation is low, easily embrittlement.

Particle anti-aging agent of the present invention directly applies in the rubber items such as natural rubber, chloroprene rubber, paracril, cis-1,4-polybutadiene rubber, styrene-butadiene rubber(SBR) and can effectively improve the anti-ozone of product, heat-resisting, resistance to subduing and abrasion resistance.Compared with prior art, particle anti-aging agent of the present invention effectively reduces the pollution to Working environment in processing and concrete use procedure, the processing units and the pipeline mouth of pipe place that have avoided the anti-aging agent of powdery to be deposited on workshop result in blockage, and staff is without the helmet with bed filtration, more convenient when work, for staff's health provides safeguard.

Concrete scheme is: antioxidant BLE, white carbon black and the Wax-for preventing rubber that described particle anti-aging agent is is 45:35:20 by ratio of weight and number carries out mixing granulation and make, adopt the anti ageing property of the particle anti-aging agent that this formula prepares good, be applicable to the rubber product high to anti-aging requirement.

Antioxidant BLE, white carbon black, Wax-for preventing rubber and the softening temperature that described particle anti-aging agent is is 40:35:15:10 by ratio of weight and number is that the pitch of 100 DEG C carries out mixing granulation and makes, the price of pitch is low, its as prepare particle anti-aging agent tackiness agent time can effectively reduce raw materials cost, the rubber item preparing has good heat-resisting, acid and alkali-resistance and wear resistance.

Preferably, antioxidant BLE, white carbon black, ground silica and the Wax-for preventing rubber that described particle anti-aging agent is is 32:24:24:20 by ratio of weight and number carries out mixing granulation and makes, the price of antioxidant BLE will be starkly lower than white carbon black and ground silica, adopt the raw materials cost of particle anti-aging agent prepared by this formula low, and can meet the processing of the rubber product lower to anti-aging requirement.

Further scheme is: described resin is one or more in C5 resin, C9 resin and coumarone indene resin, adopt C5 resin, C9 resin and coumarone indene resin can effectively increase hardness, elasticity and the ageing resistance of rubber as the tackiness agent of preparing particle anti-aging agent, good with natural rubber, elastomeric consistency, during for the production of the rubber hose of preparation and tire, there is good increasing stickiness, thermotolerance and resistance to acids and bases.

Described tar is Stockholm tar or coal tar, or both mixtures.

Another object of the present invention is to provide a kind of preparation method of particle anti-aging agent as described above, comprises the following steps:

S1): in metering kettle, drop into antioxidant BLE, be heated to 110～160 DEG C;

S2): in metering kettle, slowly drop into tackiness agent, under 110～160 DEG C of conditions, stir 10～30min to mixing, obtain the mixed solution of antioxidant BLE and tackiness agent;

S3): carrier is dropped in mixing machine, then slowly add antioxidant BLE and tackiness agent mixed solution, stir 12～18min to mixing, obtain pulverulent mixture;

S4): by feeder, pulverulent mixture is quantitatively sent into granulating extruder and carry out granulation, obtain particle anti-aging agent.
