Abstract
The invention relates to a formula of a flame-retardant rubber sheath. The formula comprises: in percents by mass, 42%-55% of vinylsilane rubber, 6%-8% of dicumyl peroxide, 12%-30% of silica, 6%-14% of ferric oxide, 4%-10% of methylphenyldiethoxysilane and 7%-12% of chloroplatinic acid. The flame-retardant rubber sheath has the advantages of good flame retardant performance, low cost, high moulding rate and the like.
Description
Technical field
The present invention relates to the elastomeric material technical field, is a kind of formula of flame retardant type rubber sheath specifically.
Background technology
Sharp increase along with urban population, Highrise buildings, hotel, large supermarket, hospital, station, airport constantly increase, the construction of subway, tunnel traffic, and the increase of large-scale Public Physical Education, public place of entertainment, public transit facility, the importance of fire-fighting, fire safety shows especially out.
What adopt both at home and abroad at present, is the flame resistant cable that magnesium oxide mineral fire-proof insulation cable and mica tape are wound around mostly.Magnesium oxide mineral fire-proof insulation cable needs special manufacturing and processing equipment, and the equipment of in addition producing magnesium oxide mineral fire-proof insulation cable not only needs import, and very expensive, and fund input is too large; In addition, the outer jacket of magnesium oxide mineral fire-proof insulation cable is full copper, higher on cost, is subject to restriction to a certain extent aspect practical application; Add the particular requirement of copper sheath magnesium oxide mineral fire-proof insulation cable in the processes such as the laying installation of process for processing, transportation, circuit and use, it is convenient as the process for processing of magnesium oxide mineral fire-proof insulation cable can not the image height molecular material, the laying installation difficulty is large, the material cost cost is high, be difficult to universal use the on a large scale, be difficult to especially promote on covil construction etc.And the flame resistant cable that mica tape is wound around, need in process of production multiple wraps, restriction due to processing condition, often easily cause seam lap place defect to occur, mica tape embrittlement after burning, easily come off, also cause fire-resistant weak effect, thereby be difficult to ensure safe and smooth under fire condition of communication, electric power.
Summary of the invention
Technical problem to be solved by this invention is to provide the formula of the flame retardant rubber that a kind of flame retardant properties is good, with low cost, ratio of briquetting is high, i.e. a kind of formula of flame retardant type rubber sheath.
Technical problem to be solved by this invention realizes by the following technical solutions:
A kind of formula of flame retardant type rubber sheath, this formula comprises vinylsiloxane rubber, dicumyl peroxide, silicon-dioxide, ferric oxide, aminomethyl phenyl diethoxy silane, Platinic chloride, the shared mass percent of described each component is as follows:
The shared best in quality per-cent of described each component is as follows:
The performance of described each component and effect are as follows:
Vinylsiloxane rubber: the rubber as the ethene silica gel product is used.
Dicumyl peroxide: the agent of vinyl rubber dedicated vulcanization, can decompose rapidly the generation free radical under higher curing temperature, thereby it is crosslinked that silicon rubber is produced.
Silicon-dioxide: the main raw of the reinforcing filler of silicon rubber claims again white carbon black.Silicon-dioxide can be divided into thermal silica and precipitated silica.Fumed silica is one of the most frequently used strengthening agent of silicon rubber,, good electrical property high by the physical strength of its cross-linked rubber of sizing material of its reinforcement, and can with other strengthening agent or weak strengthening agent use, prepare the sizing material of different service requirementss.
Ferric oxide: weak reinforcing filler, they generally do not use separately in rubber, but with silicon-dioxide use, to regulate the hardness of rubber, improve the processing performance of sizing material and oil resistance and the solvent resistance of cross-linked rubber, reduce the cost of sizing material.
The aminomethyl phenyl diethoxy silane: constitution controller, meeting hardening in the silicone rubber compounds storage process of employing fumed silica reinforcement, plasticity value descends, and loses gradually process industrial art performance, and this phenomenon is called " structurizing " effect.For preventing and weaken that the Synergist S-421 95 that this " structurizing " tendency adds is called " constitution controller ".
Platinic chloride: fire retardant can significantly improve the fire retardancy of rubber.
The invention has the beneficial effects as follows: the present invention has that flame retardant properties is good, with low cost, the ratio of briquetting advantages of higher, has increased the benefit of company.
