A kind of above-mentioned method that contains the flame retardant rubber plate of microwave activation waste rubber powder of right for preparing, its step comprises: be 30-250 part butadiene-styrene rubber with parts by weight, parts by weight are that 10-200 part microwave activation rubber powder and parts by weight are that 5-100 part chlorinated rubber is mixing evenly with three roller rubber mixing machines, be 2-40 part ANTIMONY TRIOXIDE SB 203 99.8 PCT again with parts by weight, parts by weight are 5-40 part zinc borate, parts by weight are 5-50 part APP, parts by weight are 5-40 part magnesium hydroxide, parts by weight are 0.5-20 part zinc oxide, parts by weight are 0.5-10 part stearic acid, parts by weight are 0.1-10 part antioxidant D, parts by weight are that 5-25 part carbon black and parts by weight are the composite mixing of 0.1-10 part altax, above-mentioned two kinds of mixtures are mixing evenly and make sheet with three roller rubber mixing machines, vulcanize at last and namely obtain the described flame retardant rubber plate that contains the microwave activation waste rubber powder.
Described microwave activation rubber powder adopts waste rubber powder under the microwave condition of 100-600w, activates 5-30 minute and obtains.
Preferably, described microwave activation rubber powder adopts waste rubber powder under the microwave condition of 220w, activates 10 minutes and obtains.
Described cure conditions is at 140-200 ℃, under the 15-30MPa, vulcanizes 6-10 minute.
Preferably, described cure conditions is at 150-180 ℃, under the 30MPa, vulcanizes 7-9 minute.
The fire retardant reaction mechanism of using among the present invention is as follows:
The flame retarding reaction mechanism of APP:
APP refers to the polymerization degree greater than 1500 polymer phosphate ammonium, and it is the agent of organophosphorus fire-retardant, and temperature when low violent decomposition can take place, and generates volatile PO, PO
2Free radical and NH
3, H
2The O non-flammable gases.They can play the effect of Mulberry Extract and dilution inflammable gas in gas phase, be the gas phase fire retardant mechanism.Simultaneously, violent chemical reaction takes place in APP and IPPP when temperature is higher, polyphosphoric acid and the phosphate compound that generate this moment make a large amount of esterifications of polymkeric substance, dehydration, charing, the carbon-coating generation oxygenolysis that forms at the following initial stage of effect of oxygen, heat, the dominant carbon skeleton decomposes rapidly, and be cross-linked into carbon, and stop the further pyrolysis of polymkeric substance on the one hand, stop its inner thermolysis to produce thing on the other hand and enter gas phase participation combustion processes.
The flame retarding reaction mechanism of chlorinated rubber:
Because the high energy free radical HO in the flame can react with the thermal decomposition product of other polymkeric substance, HO can react and generate H, and H can make HO regeneration again, and HO is more many, and the reaction heat in the combustion processes is just more high.Add chlorinated rubber in macromolecular material, it generates Cl when being heated the generation decomposition reaction
-, Cl
-Can generate HCl with the rubber matrix reaction, and HCl can react, and generates active lower Cl with highly active free radical HO. and H.Owing to reduced high mars free radicals such as HO and H, also just reduced the reaction heat that burning discharges, burning is slowed down or stop, play fire-retardant effect.And if generate more HCl in the combustion reactions, then HCl gas can further dilute inflammable gas, and covers material surface, intercepts inflammable gas and diffuses into the combustion space, simultaneously also stop oxygen diffusion in inflammable gas, thereby the rubber combustionvelocity is reduced or put out certainly.
The flame retarding reaction mechanism of magnesium hydroxide:
Magnesium hydroxide is inorganic additive flame retardant, can discharge moisture during decomposes, absorb a large amount of latent heat, it is low molecular speed that the actual temperature that both can reduce the flame of material surface makes the polymer degradation that slows down, reduce the generation of combustiblesubstance, can water down the temperature of material surface oxygen again by the steam that discharges, the burning that makes material surface difficulty is carried out.Magnesium hydroxide is conducive to form surface char, stops entering of heat and oxygen.The magnesium oxide that resolves into simultaneously still is good refractory materials.In case so burning things which may cause a fire disaster is eliminated, burning can stop voluntarily.
The fire retardant mechanism of ANTIMONY TRIOXIDE SB 203 99.8 PCT
Antimonous oxide belongs to additive flame retardant, with other fire retardant, smoke suppressor and usefulness, produces synergistic effect.Sb
2O
3At the burning initial stage, at first can fusion, fusing point is 655 ℃, forms the protective membrane secluding air at material surface, again by inner thermo-negative reaction, the reduction temperature of combustion.Sb under the state of high temperature more
2O
3Be vaporized, diluted oxygen concn in the air, thereby play fire retardation.
The fire retardant mechanism of zinc borate
Zinc borate begins to discharge crystal water at 300 ℃, under the effect of halogen compounds, generates halogenation boron, zinc halide, suppresses and catches free hydroxyl, stops combustion chain reaction; Form the solid phase tectum simultaneously, isolated oxygen on every side, prevention flame burns away and has the cigarette effect of pressing down.
Therefore magnesium hydroxide, APP, zinc borate, antimonous oxide, chlorinated rubber can reach the fire-retardant purpose of this flame-retardant system by the synergy of multiple effect.
And antioxidant D is the N-Phenyl beta naphthylamine, can use with other anti-aging agent, and also be one of anti-aging agent of using always.Be applicable to natural rubber, synthetic rubber and latex.It is to air, heat and subdue and aging protective effect is arranged, but goods are met phototropic.
Altax is dibenzothiazyl disulfide, generally as natural rubber, synthetic rubber, the universal promotor of reclaimed rubber.Its sulfuration critical temperature is higher to be 130 ℃, and temperature is active increasing more than 140 ℃, significant aftereffect arranged, operational safety.In G type chloroprene rubber, can make retarding agent, softening agent, in W type chloroprene rubber, make cure modifier.When being used for latex, vulcanization rate is slower, but can reduce the tendency that contains the scorching of promotor EZ latex sizing material.Altax easily disperses in sizing material, and is pollution-free, but bitter taste is arranged, and should not mainly for the manufacture of tire, sebific duct, adhesive tape, rubber overshoes, adhesive plaster and general industry goods, also be used for white and light goods for the goods that contact with food.
The present invention forms the flame retardant rubber plate by making the waste rubber powder, butadiene-styrene rubber and the fire retardant that contain microwave activation, not only fully regeneration waste rubber powder, eliminated environmental pollution, also can reach the purpose of flame retardant rubber, made the flame retardant rubber plate can be applied to broader field.Simultaneously, the comprehensive cost of flame retardant rubber plate of the present invention is also very low, has practicality.
