Description
Technical field
The present invention relates to a kind ofly both had high temperature resistantly, have the high temperature resistant halogen-free flame-retardant rubber conveyer belt sizing material and the conveying belt thereof of flame retardant effect again, belong to chemical rubber novel material manufacturing technology field.
Background technology
Rubber conveyer belt is a kind of traditional rubber item, and is of many uses.Be mainly used in the transmission and the conveying of all kinds of materials, like the conveying of the underground material of mining industry and the loading and unloading on ground, the loading and unloading of wharf materials, the drainage of industrial and mining enterprises' slag.As far back as the beginning of the fifties, it is master's conveying belt technology that China has just introduced with natural (NR) robber materials from the former Soviet Union.Afterwards, along with China's progress of science and technology and modernization construction progressively advance, rubber conveyer belt technical study and product development have had great variety, have occurred many novel materials and new technology in succession.Like product innovations such as X 050 (CR) fire retarding conveying band, high temperature resistant ethylene-propylene rubber(EPR) conveying belt.The halogen fire retardants that adopt carry out fire-retardant more on flame-retarded technology.Add the scientific formula technology at the high temperature resistant technical high-temperature resistant rubbers such as ethylene-propylene rubber(EPR) and butyl rubber that adopt more.But can satisfy the demand of China's economic construction development far away, more still have big gap with foreign technology.The slag band that particularly many blast furnaces just have been discharged on the conveying belt flare, is emitting dense smoke very big to the infringement of conveying belt, has shortened the work-ing life of conveying belt.
X 050 (CR) fire retarding conveying band technology fire-retardant do not reach environmental requirement, and the amount of being fuming is big during burning, and contains a large amount of toxic and harmfuls and corrosive fume.Cause the survivor to get lost, death by suffocation.Corrosive fume also can etching apparatus, and instrument and connection line make major disasters such as control is malfunctioning.
The ethylene-propylene rubber(EPR) conveying belt approximately only has the working life about 2 months usually under 180 ℃ high temperature working conditions.
For example: 1. coal mining industry is badly in need of the high-performance halogen-free flame retardant conveying belt to reduce the disaster that the fire burning causes.2. the high temperature furnace slag of smelting industry discharging conveying belt is badly in need of high temperature resistant and halogen-free flameproof conveying belt to solve the fire-retardant and short life difficult problem of conveying belt.
Therefore, urgent need was both high temperature resistant in the industrial construction production, long lifetime conveying belt product that again can highly effective flame-retardant.
Summary of the invention
Purpose of design: avoid the weak point in the background technology, design and a kind ofly both had high temperature resistantly, have the high temperature resistant halogen-free flame-retardant rubber conveyer belt sizing material and the conveying belt thereof of flame retardant effect again.
Plan: in order to realize above-mentioned purpose of design, 1, the design of selecting resistant to elevated temperatures rubber for use, be one of technical characterictic of the present invention.The purpose of doing like this is: because high-temperature resistant rubber is under hot conditions, its physics and chemical property remain unchanged basically, and have and conveying belt reinforcing cord excellent adhesion performance and flame retardant efficiency.2, the employing of halogen-free flame retardants is two of a technical characterictic of the present invention.This purpose of wanting appearance to do is: fire retardant additive without halogen is main with inorganic metal oxyhydroxide mainly.This based flame retardant, non-volatile during burning, the amount of being fuming is few, does not produce corrosive gases.Do not resemble halogen fire retardant commonly used, though fire-retardant, discharging a large amount of poisonous and harmfuls during burning has the corrosive black smoke, causes the bigger disaster of secondary of fire.The selected fire retardant of the present invention does not have the phenomenon of hanging down and dripping and producing black smoke when burning, the obnoxious flavour that produces of comparing greatly reduces, and is nuisanceless fire retardant.3, the employing of rubber reinforcing filler is three of a technical characterictic of the present invention.The purpose of doing like this is: in resistant to elevated temperatures rubber, add rubber reinforcing filler, not only have high the filling and do not reduce properties of rubber, and have excellent dispersiveness, short mix, nothing cohesion tendency; Secondly, have excellent drawability, its surfactivity is high, pull between performances such as intensity, tear strength, compression set and can obtain good balance, and ageing-resistant performance is good, compression set is low and have height stretches performance surely.For example: precipitated silica is mainly as tree elastomer and elastomeric strengthening agent etc.The application adds heavy purpose of dissolving the method WHITE CARBON BLACK and is: the one, and the reinforcing effect of raising high-temperature resistant rubber conveying belt; The 2nd, the flame retardant resistance of raising rubber conveyer belt increases the service life; The 3rd, because precipitated silica is the important reinforced filling of rubbery system; Its chemical index and physical properties of rubber compound have extremely close relation; Through analysis, can dope its dispersion state and reinforcing effect in the sizing material system well to the precipitated silica chemical index.4, the employing of tackifier is four of technical characterictics of the present invention.The purpose of doing like this is: tackifier mainly are the bounding forces of reinforcing cord and film as tackiness agent, and the application adds tackifier can make the sticking power of the high temperature resistant halogen-free flame-retardant sheet rubber of institute's moulding obviously strengthen.
Technical scheme 1: high temperature resistant halogen-free flame-retardant rubber conveyer belt sizing material; It is characterized in that (weight ratio): high-temperature resistant rubber is that 90-110, halogen-free flame retardants are that 170-190, reinforcement auxiliary agent are that 35-45, tackifier are that 7-13, vulcanizing agent are that 3.5-5.5, antioxidant A are that 1.5-2.5, anti-aging agent B are that 1.0-2.0, promotor are 1.0-2.0, and above-mentioned component increases in proportion or reduces.
Technical scheme 2: the high temperature resistant halogen-free flame-retardant rubber conveyer belt, it comprises rubber conveyer belt, is equipped with high temperature resistant halogen-free flame-retardant rubber conveyer belt film press vulcanization on the high temperature vulcanizing press on the enhancing cord of described rubber conveyer belt and forms.
The present invention compares with background technology; High temperature resistant and the halogen-free flameproof two big technological deficiencies of current rubber conveyer belt industry product have been solved; It is blank in the application of halogen-free flameproof and high temperature resistant working conditions elastomeric material to have filled up the rubber conveyer belt product; Improved the security that the conveying belt product uses greatly, the working life that has prolonged product.
Fig. 1 is the structural representation of high temperature resistant halogen-free flame-retardant rubber conveyer belt.
