Summary of the invention
Object of the present invention is exactly the defect existed for prior art, and provide a kind of oil sludge of utilization of waste material to prepare the production technique of reclaimed rubber, its technical scheme is:
(1) with the sodium p styrene sulfonate aqueous solution for clean-out system, adopt thermochemistry washing out method process oil sludge, fully precipitate, get upper strata crude oil and time upper liquid, merge as mixed solution for subsequent use;
(2) get waste old and pulverize formation rubber powder;
(3) in activation pot, the mixed solution of rubber powder and step (1) reacts under initiator exists;
(4) High Temperature High Pressure desulfurization;
(5) by the reclaimed rubber refining glue after desulfurization, rubber product is made.
Step (1) adopts thermochemistry washing out method to process oil sludge.Research shows, oil sludge not only contains bituminous matter and the high molecular polymer of certain content, and these bituminous matters and high molecular polymer are good tenderizers in waste rubber regenerative process; Meanwhile, also containing high molecular polymer and sulfur alcohol compounds such as polyacrylamides in oily sludge, these materials are indispensable activators in waste rubber regenerative process.But, different according to source, oil sludge is also containing inorganic impurities such as a large amount of grains of sand, earth, heavy metal salts, and the usual particle diameter of these materials is larger, not only the performance of reclaimed rubber is had a negative impact in waste rubber regenerative process, larger infringement is produced to reclaiming process device simultaneously.
After using the thermochemistry washing out method process of step (1), through fully precipitating, the crude oil in oil sludge, water are fully separated with inorganic impurity, are obviously divided into four layers.Upper strata is black jack layer, and the aqueous solution of secondary upper liquid mainly containing sodium p styrene sulfonate, third layer is non-scavenging solution, and orlop is inorganic impurity.Because upper strata crude oil contains aforementioned tenderizer and activator, therefore, step (1) is the equal of the enriching and purifying step of active substance.
Advantageously, the processing condition of step (1) are as follows: according to the ratio of weight ratio 1:2-1:6, joined by oil sludge in the sodium p styrene sulfonate aqueous solution of 5-10wt%, and adjustment pH is 10-14; Stir 0.5-2 hour at 50-90 DEG C, fully precipitate, get upper liquid and time upper liquid, merge as mixed solution for subsequent use.In a preferred embodiment, according to the ratio of weight ratio 1:3-1:5, joined by oil sludge in the sodium p styrene sulfonate aqueous solution of 6-9wt%, adjustment pH is 11-13; Stir 1-2 hour at 60-80 DEG C, fully precipitate, get upper liquid and time upper liquid, merge as mixed solution for subsequent use.In an embodiment, according to the ratio of weight ratio 1:4, oil sludge is joined in the sodium p styrene sulfonate aqueous solution of 8wt%, regulate pH to be 12; Stir 2 hours at 70 DEG C, fully precipitate, get upper liquid and time upper liquid, merge as mixed solution for subsequent use.
Waste old source is varied, such as, can be junked tire, sebific duct, rubber overshoes.Through classification cleaning, these waste olds are taked normal temperature crushing up or pulverize at low temperature method to pulverize and are formed rubber powder, preferably normal temperature crushing up.Rubber powder size is less, with activator and tenderizer effect stronger, distribute in the substrate more even, performance is more stable; But when particle diameter is too little, the inierpeneirating network structure that rubber powder particle and activator are formed and percentage of grafting reduce.Advantageously, the processing condition of step (2) are as follows: get waste old classification cleaning; Pulverizing and forming particle diameter is 50-150 object rubber powder.In a preferred embodiment, waste old classification cleaning is got; Pulverizing and forming particle diameter is 80-120 object rubber powder.In an embodiment, get waste old classification cleaning; Pulverizing and forming particle diameter is 100 object rubber powders.
Step (3) is priming reaction step, the mixed solution of rubber powder and step (1) reacts under initiator exists, form graft copolymer or interpenetrating(polymer)networks or wrap up winding arrangement, thus change the surfactivity of rubber powder, improve itself and the polymer materials consistency especially and between activator polymer materials of the same type.The activated rubber powder shock resistance obtained significantly is improved, and tensile strength is higher, and elongation at break can up to more than 400%.
Contriver finds, in priming reaction step, not only there is the high molecular polymers such as the polyacrylamide in the upper strata crude oil of step (1) and the grafting between sulfur alcohol compound and rubber powder or copolyreaction; And grafting between the high molecular polymer such as the aqueous solution of the secondary upper liquid that there is step (1) namely containing sodium p styrene sulfonate and polyacrylamide and rubber powder or copolyreaction.Because reaction system is carried out under solution state, we believe, the mechanism of step (3) may be emulsion polymerization.In addition, it is pointed out that the crude oil weight obtained due to step (1) is obviously greater than the secondary upper liquid of step (1), the moisture existed in reaction system can't produce significant negative impact to subsequent reactions.
In priming reaction step, the initiator used is benzoyl peroxide or dibenzoyl peroxide; Be preferably benzoyl peroxide.The 0.01-0.1wt% of initiator content normally raw material gross weight.Reaction process advantageously uses inert atmosphere protection, can improve efficiency of initiation like this.
Advantageously, the processing condition of step (3) are as follows: in activation pot, according to the ratio of weight ratio 1:2-1:20, join in the mixed solution of step (1) by the rubber powder of step (2); Then add appropriate benzoyl peroxide, stir under an inert atmosphere and raw material is fully mixed, be warming up to 50-70 DEG C, reaction 2-12 hour.In a preferred embodiment, in activation pot, according to the ratio of weight ratio 1:4-1:10, the rubber powder of step (2) is joined in the mixed solution of step (1); Then add appropriate benzoyl peroxide, stir under an inert atmosphere and raw material is fully mixed, be warming up to 50-60 DEG C, reaction 3-8 hour.In an embodiment, in activation pot, according to the ratio of weight ratio 1:5, the rubber powder of step (2) is joined in the mixed solution of step (1); Then add appropriate benzoyl peroxide, stir under an inert atmosphere and raw material is fully mixed, be warming up to 60 DEG C, react 5 hours.
Step (4) is High Temperature High Pressure desulfurized step, is at about 200 DEG C or higher high temperature and S-S key and the C-S key of breaking rubber under being greater than 10 atmospheric high pressure.Due to the existence of step (3), in the desulfurized step of step (4), can realize preferably " do not destroy rubber C-C main chain and just cut off sulfide linkage and be cross-linked site; be i.e. a sulphur, two sulphur and polysulfide associative key ", thus on higher degree, remain the physical and mechanical properties of reclaimed rubber.
Need not discharging, step (4) can directly use thermal source to be pressurizeed by the heating raw materials of step (3).Advantageously, the processing condition of step (4) are as follows: by the heating raw materials in activation pot to 180-260 DEG C, control pressure at 1.8-3.0MPa, and insulation 2-10 hour, obtains the reclaimed rubber after desulfurization.In a preferred embodiment, by the heating raw materials in activation pot to 200-240 DEG C, control pressure at 2.0-2.8MPa, insulation 3-8 hour, obtains the reclaimed rubber after desulfurization.In an embodiment, by the heating raw materials to 220 in activation pot DEG C, control pressure at 2.4MPa, be incubated 5 hours, obtain the reclaimed rubber after desulfurization.
Step (5) first carries out release cooling, discharges the gas in activation pot, then discharging.Tabletted is carried out in the refiner of reclaimed rubber after desulfurization in moulding equipment and mill, makes regenerated rubber product.Refiner adopts φ 450 × φ 510 type, and front and back rolling curve velocity ratio is 38.4:64.2m/min; Mill adopts φ 450 × φ 510 type, and front and back rolling curve velocity ratio is 24.6:52.3m/min.Advantageously, the processing condition of step (5) are as follows: release cools, discharging; Use refiner and mill by the reclaimed rubber refining glue after desulfurization, refine into the regenerated rubber film of different thickness.Carry out mixing and sulfuration further and can also make the rubber items such as highway deceleration strip, achieve the recycling of refuse.
