Description

Low-smoke low-halogen plastic cover colliery Fabric Solid-woven Fire-resistant Conveyer Belt
Technical field
The present invention relates to colliery Fabric Solid-woven Fire-resistant Conveyer Belt technical field, particularly relate to a kind of low-smoke low-halogen plastic cover colliery Fabric Solid-woven Fire-resistant Conveyer Belt.
Background technology
Plastic cover colliery Fabric Solid-woven Fire-resistant Conveyer Belt, i.e. PVC load-transfer device are the maximum a kind of load-transfer devices of current underground coal mine consumption.It has good, the wear-resisting and flame-retardant and anti-static of impact resistance, tensile property, the advantage such as cheap; But for a long time, because China's mining flame-retardant load-transfer device does not control and specification the smog produced time fire-retardant and toxicity, underground coal mine uses the PVC load-transfer device of high cigarette height halogen everywhere.Load-transfer device is once namely burning produces a large amount of smog and hydrogen halides poison gas, very harmful to coal mine underground operators.Show combustible product toxicity research and Fire Data in the world, poisoning dead number of suffocating in coal-mine fire accident is far more than directly being burnt dead number.For PVC load-transfer device, press down cigarette during burning, suppress hydrogen halides to be have identical importance with fire-retardant.
At present, in the world the cigarette that presses down of coal mine conveying belt is pressed down to halogen problem and more and more payes attention to, the U.S. has started in 2009 to control, in smoke density and toxicity, to hold hearing for several times at mine conveying belt, prepares the content that revision load-transfer device Standard entertion controls smoke toxicity; Germany has added the code regulations of load-transfer device smoke toxicity in mine safety hygienic standard regulations; China's load-transfer device industry proposes the Discussion On Development of low-smoke low-halogen mine conveying belt for a long time, does not in these years get along with always.
One. low halogen
Low halogen refers to that load-transfer device discharges less hydrogen halide (mainly hydrogen chloride and hydrobromic acid) when burning.
In the PVC load-transfer device formula of current China widespread production, employ Vinyl chloride resin (pvc) and halogenated flame retardant in a large number.They can discharge a large amount of hydrogen halides poison gas when burning, and hydrogen halide belongs to mucous membrane asphyxiating noxious gas, and can cause expiratory dyspnea when concentration is enough large, suffocate even dead, be one of poison gas material important in fire smoke.
Vinyl chloride resin can decompose when heated combustion and discharges a large amount of HCl gas, and its chemical decomposition reaction equation is:
(CH 2CHCl) n+2.5nO 2→2nCO 2+nHCl↑+nH 2O
Halogenated flame retardant is a kind of efficient flame-retarding agent the most often used in load-transfer device, it mainly refers to containing chlorine [Cl], the fire retardant of bromine [Br] element, common are trichloroethyl phosphate [TCEP], 52# chlorinated paraffin, 70# chlorinated paraffin, triaryl phosphate, deca-BDE etc., its fire retardant mechanism is: under combustion conditions, halogenated flame retardant (for chlorine-containing flame retardant) decomposes goes out chlorine radical Cl*, chlorine radical Cl* can generate HCl with the hydroperoxyl radical in flame retarding reaction or polymer reaction further, hydrogen chloride (HCl) again can with the high activity Hydroxyl radical HO * water generation reaction that formed in combustion reaction process, course of reaction is as follows:
RCl→R+Cl*
Cl*+H*→HCl↑
Cl*+R*H→HCl↑
HCl+HO*→H 2O+ Cl*
As from the foregoing: halogenated flame retardant at high temperature releases hydrogen halides, catch high activity Hydroxyl radical HO * and H* of a large amount of propagation in combustion reaction process, thus interrupt chain oxidizing reaction, slow down or stop burning.Therefore halogenated flame retardant can release a large amount of hydrogen halides in combustion.Here is the halogen content of conventional key component material in PVC load-transfer device, in table 1.
Table 1 halogen content dial measuring gauge
。
And the cheapness and physical property preceence of Vinyl chloride resin temporarily cannot be replaced by High molecular materials such as rubber.
Two. low cigarette
Low cigarette refers to that fire retarding conveying band discharges low-smoke when burning.
In existing domestic PVC load-transfer device formula, the material such as Vinyl chloride resin and various fire retardants can discharge a large amount of smog when burning, and the be fuming amount of common each component material when burning represents in Table 2(smoke density and the degree of being fuming).
The be fuming amount of each component material of table 2 when burning
。
As shown in Table 2, in each component material, the amount of being fuming of Vinyl chloride resin is the highest, and its mechanism of being fuming is: in Vinyl chloride resin combustion process, generates conjugated double bond unsaturated hydrocarbon after de-HCl, then carbochain fragments into low molecule product, free radical etc., molecule is reset, and cyclisation forms benzene nucleus, aggregates into the resin of condensed-nuclei aromatics race, finally become coke and graphitization carbon granules, the combustion reaction formula of such as benzene can be expressed as:
C 6H 6+4.5O 2→3(H 2O+CO 2)+3C
Because C and H burning generates CO 2and H 2the speed of response of O is identical, has unnecessary charcoal to separate out in the reaction, produces black smoke, releases so Vinyl chloride resin has a large amount of cigarette when burning.
In order to solve the technical barrier in the domestic and international fire retarding conveying band field of this long-standing problem, the invention discloses the technical scheme of a kind of low-smoke low-halogen plastic cover colliery Fabric Solid-woven Fire-resistant Conveyer Belt.
