Description
Technical field
The present invention relates to fabric core fire retarding conveying band tectum rubber based on CPE and its preparation method and application, processing characteristics is good, have good flame retardant properties and mechanical strength concurrently, can be used for fire retarding conveying band tectum rubber, belong to rubber cover technical field.
Background technology
General use fabric core fire retarding conveying band is the main tool of colliery and electric power ground transported material.Because common rubber conveyer belt is inflammable substance, when running into fire and strong thermal radiation, the material structural strength of conveying belt sharply declines, and component caves in, and conveying belt causes great fire failure repeatedly, can not meet fire-retardant requirement.Therefore, the conveyor belt material on colliery and electric power ground must have flame retardant properties.
Through years of researches exploitation, countries in the world define the kind of fire retarding conveying band, the situation of multi-size.On current ore deposit fire retarding conveying band tectum elastomeric material be roughly divided into two classes: PVC, PVG fire-retarding conveyer belt coating rubber that the first kind is is matrix with polyvinyl chloride or rubber and polychloroethylene blended material; The fire-retarding conveyer belt coating rubber that the second is is directly matrix with conventional rubber as styrene-butadiene rubber(SBR) (SBR) or chloroprene rubber (CR).
Although above-mentioned fire-retardant rubber material all has comparatively moderate mechanical property and flame retardant properties, but also there are some problem: PVC and PVG is plastics, although flame retardant properties is better, but its toughness and flexibility are still not as good as conventional rubber material, conveying belt easily skids, sideslip, groove forming character and flexibility also poor, work-ing life is short; Adopt styrene-butadiene rubber(SBR) to be tectum elastomeric material, its flame retardant properties is unsatisfactory, needs to fill a large amount of fire retardant, makes Mechanical Fluctuation obvious; And adopting chloroprene rubber to be tectum elastomeric material, processing characteristics is poor, easily glutinous roller, easy incipient scorch, technology controlling and process difficulty in the course of processing, and neoprene latex cost is high, does not possess cost advantage.Therefore, how developing and a kind ofly take into account fire-retardant, mechanical property, processing characteristics and cost advantage general use fabric core fire-retarding conveyer belt coating rubber material, is imperative.
Summary of the invention
The object of this invention is to provide a kind of fabric core fire retarding conveying band tectum rubber based on CPE and its preparation method and application, product possesses reinforcement and fire-retardant double effects simultaneously, finally reaches the balance of high mechanical strength and excellent flame retardant performance.

Described strengthening agent is nano silicon and/or carbon black N220.The particle diameter of described nano silicon is 10-40nm.Wherein nano silicon filler both had reinforced effects, was beneficial to again and improved flame retardant properties, particularly solved the problem that carbon black produces a large amount of Mars in combustion, can not certainly put out.For CPE, compared to conventional carbon black, there is more excellent reinforcing property using nano silicon as reinforcing filler, during simultaneously nano silicon burning, contribute to minimizing glow phenomenon, there is self-extinguishing.Therefore, in tectum elastomeric material, add silicon-dioxide, while ensureing Flame Retardancy energy, more significantly can improve the mechanical strength of material.But there is certain influence to processing characteristics.
Described softening agent is dioctyl phthalate (DOP) DOP.CPE is as the one of non-traditional rubber, only have and just have elastomeric characteristic when chlorine element proportion reaches certain limit, snappiness own is also bad, but by the use of corresponding softening agent, can effectively improve its plasticity-and autohension, ensure the tensile elongation of sizing material.
Described metal oxide is nano zine oxide and/or nano magnesia.Described metal oxide particle size range is 10-100nm.The nano silicon adopted is precipitated silica.Add metal oxide and not only play activation, and nano-scale oxide specific surface area is large, activity is larger, is conducive to absorbing the acidic substance of releasing in ageing of rubber process, has obvious protective effect.
Described anti-aging agent is 6PPD, the mixture of one or more namely 4020, in RD and Microcrystalline Wax.The aging resistance adding guarantee material of anti-aging agent.
Described vulcanizing agent is Sulfur; Vulcanization accelerator is the mixture of one or more in dithio-bis-benzothiazole DM, N-tertiary butyl-2-[4-morpholinodithio time yellow acid amides NS, tetramethyl-thiuram disulfide TMTD or N-cyclohexyl-2-[4-morpholinodithio base sulphenamide CZ and ethylene thiourea NA-22.
The preparation method of the fabric core fire retarding conveying band tectum rubber based on CPE, step is by weight: in Banbury mixer, add chlorinatedpolyethylene 20-100 part, styrene-butadiene rubber(SBR) 1-80 part, then fire retardant 10-40 part is added successively, metal oxide 5-10 part, stearic acid 0.2-2 part, anti-aging agent 0.5-10 part, strengthening agent 30-60 part, softening agent 10-30 part, finally add vulcanizing agent 1-3 part and vulcanization accelerator 1-5 part, banburying 8-12min, then refining is opened on a mill until, thin-pass 4-6 time, mix further, namely the fabric core fire retarding conveying band tectum rubber based on CPE is obtained.
