Abstract

The invention discloses a tire flap rubber material, belonging to the field of manufacturing of rubber tires. According to the formula of the rubber material, 60-mesh rubber powder is added, carbon black is removed, and a tackifier and a flowable agent are added, thereby keeping the softness of the finished flat product for a long time, improving the hand feel of the finished flat product and lowering the production cost to some degree on the premise of not lowering the original physical properties. Meanwhile, the invention solves the problem that the carbon black can bring about massive dust and jeopardize good health of working personnel in working places.

Description

A kind of tire flap sizing material
Technical field
The present invention relates to a kind of tire flap sizing material, belong to rubber tyre and make the field.
Background technology
Rim strip is claimed lining band again, press strip.Refer to be used to protect the inner tube of a tyre the endless rubber belt that the face of closing does not receive the wheel rim wearing and tearing.To the rim strip of making all kinds of all steels and half steel tire, require properties of rubber can resist flex crack, tear-resistant, heat-resisting and have a certain rigidity.The carbon black that has all added mix quality 5~6% in the existing sizing material plays reinforcement and filling effect.Sooty adds makes rubber unvulcanizate deposit after for some time or carbon black add-on degradation such as flexibility when big on the one hand, makes the dust of working space big on the other hand, and the harm staff's is healthy.
Summary of the invention
The present invention has overcome that rim strip softness that existing carbon black causes descends and problem such as the dust of worker's Working environment is big, and a kind of new tire flap sizing material is provided.This sizing material has added 60 purpose rubber powders in prescription; Removed carbon black; And add tackifier and flowing agent etc., and make it under the prerequisite that does not reduce original rerum natura, can not only keep the pliability of rim strip finished product for a long time; Improved the handling property of rim strip finished product, and production cost obtains reduction to a certain degree.The more important thing is the sanitary condition of production scene is greatly improved.
Technical scheme of the present invention is: a kind of tire flap sizing material; It is characterized in that; Its component and weight part thereof are tree elastomer 10~20, styrene-butadiene rubber(SBR) 10~30, shoddy 40~70, rubber powder (60 order) 9~12, light calcium carbonate 3~5, zinc oxide 2~3, Triple Pressed Stearic Acid 1.0~1.5, sulphur 1.0~1.5, anti-aging agent 1.0~2.0, promotor 0.5~0.8, tenderizer 3~5, tackifier 1~2, flow dispersion agent 0.5~1.0.
Said anti-aging agent is anti-aging agent RD, 4010NA or 4020 etc.; Said promotor is rubber accelerator M, DM, CZ, SP-C, TMTD, PZ etc.; Said tenderizer be molecular weight 300-600 hydro carbons or arene (like machine oil, paraffin oils, aromatic hydrocarbon oil, etc.); Said tackifier are octyl group phenolic tackifying resins (203-resin), p tert butylphenol formaldehyde resin or tertiary butyl phenol aldehyde tackifying resin; Said flow dispersion agent is conventional rubber flow dispersion agent HM-24 etc.
Said rubber powder is the Powdered elastomeric materials of 60 purposes for handling the granularity that obtains by junked tire through grinding and processing.The mixture of said shoddy for forming through pulverizing, regeneration (desulfurization) and refining by junked tire.
Preparing method: use rubber internal mixer; Order of addition(of ingredients) is: tree elastomer, styrene-butadiene rubber(SBR), shoddy and rubber powder drop into Banbury mixer and pressed bolt 2~3 minutes; Add light calcium carbonate, zinc oxide, Triple Pressed Stearic Acid, anti-aging agent, tackifier and flow dispersion agent then and pressed bolt 3~5 minutes; Add tenderizer then, discharge, extrude down sheet and form master batch; Master batch adds sulphur, promotor mixing at last, and following sheet is cooled to the making that room temperature is accomplished rim strip glue.
The invention has the beneficial effects as follows:
1, because rubber powder itself is a kind of sooty glue that contains; It can not only play sooty reinforcement, filling effect, and add-on can not cause the finished product changes in hardness bigger when strengthening; Thereby the pliability that has kept finished product, the while has also increased the stability of finished product hardness.
2, use 60 order rubber powders that the sanitary condition of the production scene of mixing process is greatly improved, everywhere unlike the carbon black that equally can find in the past to fly, the also bad cleaning of health of equipment simultaneously.Also guaranteeing that in varying degrees worker's Working environment improves, and has avoided the occupational illness because of using carbon black to cause.
3, because the price of 60 order rubber powders almost is about half of carbon black price; And the usage quantity of rubber powder be the carbon black usage quantity 1-2 doubly between; The consumption of other material of being adjusted in the prescription is fewer again, therefore makes whole formulation cost obtain decline to a certain degree.
Embodiment
