Abstract
The elastomer material is prepared through plastication of polypropylene grafted by maleic anhydride, nitrile rubber aminated by amine initiator, chlorinated polyethylene, plasticizer, stearic acid, antioxidant 1010 and stannous chloride in certain proportion. The said product is processed and formed through the method for thermoplastic plastic rather than the complicated sulphurization process for rubber product, and this can save power, reduce cost and raise productivity. The said material may be used for heat and oil resisting product, such as sealing part, pipe, etc and its performance may reach that of similar rubber product.
Description
The invention belongs to high molecular polymer Thermoplastic Elastic Material Used and preparation method thereof.
Before the present invention, it is the type material that the eighties grows up that rubber plastic blend is made thermoplastic elastomer, this material shows as the character of rubber at normal temperatures, but available traditional plastic shaping working method makes, as: extrude, modes such as injection, mold pressing.According to the U.S. (A.Y.Coran, Rubb, Chen, Technol, 1985,56 (2), 1044) introduce, U.S.'s human increase-volume methods such as A.Y.CoRAN in 1985 have been made the nitrile rubber/polypropylene blended thermoplastic elastic body of process compatible, and have applied for United States Patent (USP) (US.4455139,1982), U.S. MONSANTO company has adopted this technology, and has made commodity (Elastomeric, 1985,117 (10), 35-36) trade name is Geolast701-80,701-87, the 703-40 series product.Its technology is that sulfuration generates a spot of grafts on end amido paracril, improve the consistency between polypropylene/paracril like this, effect is fine, the physical performance index of its product is: tensile strength 14.1MPa, elongation at break 390%, compression set (100 ℃ * 22h) 39%, oil absorbency (machine oil) (125 ℃ * 70h) 12%.Traditional rubber-plastic elastomer material generally all is to adopt rubber vulcanization process machine-shaping, complex process.
The present invention has proposed new technical scheme in order to overcome the deficiency of prior art, on the resilient material basis of prior art, adds the polypropylene of maleic anhydride graft and aminated paracril simultaneously and and increases its consistency with ethylene chloride.
Main points of the present invention are: at first with maleic anhydride and polypropylene grafted, to increase the consistency of rubber and plastic when mixing, maleic anhydride and polypropylene are after connecing certain proportion and mediating in kneader, add initiator Diisopropyl azodicarboxylate or dibenzoyl peroxide again, extruding pelletization in forcing machine promptly becomes the polypropylene of grafting; Paracril is after adding antioxidant MB, plasticates in two roller mills, then adds amine and draws the method agent, makes it aminated, promptly becomes aminated paracril; In two roller mills, with the polypropylene of above-mentioned grafting, aminated paracril, chlorinatedpolyethylene, softening agent, hard ester acid, antioxidant 1010, the tindichloride slabbing of plasticating in proportion, pelletizing promptly becomes rubber-plastic elastomer material of the present invention.
The prescription of rubber-plastic elastomer material of the present invention is (weight %):
Paracril NBR (aminated) 20～60
Polypropylene PP (grafting) 72.8～15
Chlorinatedpolyethylene CPE 5～10
Antioxidant 1010 0.1～0.5
Hard ester acid HSt 0.1～0.5

2O 1～5
The present invention carries out aminated amine kind to paracril NBR diethanolamine, trolamine, triethylenediamine, dimethyl formamide, can appoint to get a kind ofly, also can appoint and get two kinds, but total weight parts is constant.O-phthalic acid dibutyl ester in the prescription (DOP), also the dibutyl phthalate (DBP) of available equal portions (DBP) replaces, and stearic acid is a lubricant, and o-phthalic acid dibutyl ester (DOP) or dibutyl phthalate (DBP) (DBP) they are softening agent, tindichloride SnCl
2.2H
2O is a promotor.
The preparation of rubber-plastic elastomer material of the present invention is carried out as follows:
(1), maleic anhydride and polypropylene grafted:
The polypropylene of 100 weight parts risen to 100 ℃ in thermostat container after, the maleic anhydride that adds 1～20 weight part, with 10 weight parts is good, move into again in the kneader of 1000 rev/mins of revolutions and mediated about 5 minutes, then drip initiator Diisopropyl azodicarboxylate 0.1～10 weight part, with 0.5 weight part is good, perhaps replace with the dibenzoyl peroxide that waits weight part, pour in the forcing machine, three sections temperature of forcing machine are that 120～140～170 ℃, screw rod revolution are that extruding pelletization is standby about 25 rev/mins.
(2), the aminated paracril of preparation:
The paracril of 100 weight parts is added the antioxidant MB of 0.1～10 weight part, is good with 1 weight part, plasticates in two roller mills, and about 100 ℃ of temperature after plasticating 2 minutes, are added the amine of 0.5～5 weight part again, and are after mixing about 2 minutes, standby.
(3), the preparation of rubber-plastic elastomer material:
With corresponding weight part of each batching in the above-mentioned prescription, add in two roller mills, about 200 ℃ of roller temperature were plasticated about 5 minutes, i.e. slabbing, pelletizing then.
Rubber-plastic elastomer material of the present invention is compared with the material of prior art, has following advantage: this material available heat thermoplastic plastic working method forming process, need not use rubber item sulfurized complicated technology; The material of prior art is a small amount of grafts of sulfuration generation on end amido paracril just, consistency key between paracril and the polypropylene is grafts, and the aminated grafting of the paracril in the rubber-plastic elastomer material of the present invention, be better than prior art greatly, improved the consistency that rubber and plastic refines altogether greatly; Prior art is the binary blend, that is: polypropylene and paracril, the present invention is a tertiary blending, that is: polypropylene, chlorinatedpolyethylene, paracril, the physical performance index of its product is: tensile strength 14.0MPa, elongation at break 410%, and compression set (100 ℃ * 22h) 35%, oil absorbency (machine oil) 12%.Clearly compression set is better than prior art as can be seen, and all the other indexs are all approaching, and product technology of the present invention rationally, simply, can the replacement fluorine elastomeric material, be used for temperature resistant encapsulation loop material and heat resistant oils hose material, can reduce cost save energy significantly.The Guo Shi hardness A of material of the present invention is 79; After hot air aging, changes in hardness is 3%, and tensile strength is changed to 11%, and elongation change is-20%; After wearing out in deep fat, changes in hardness is 3%, and tensile strength is changed to 10%, and elongation change is-8%, and changes in weight is-3%.
