Abstract
The invention provides an ethylene-propylene-diene monomer (EPDM) rubber gasket, which comprises the following components in percentage by weight: 40 to 50 percent of EPDM rubber, 30 to 40 percent of carbon black, 1 to 3 percent of stearic acid, 15 to 25 percent of softening oil, 1 percent of anti-ageing agent, 1 to 3 percent of vulcanizing agent and 1 to 3 percent of vulcanizing accelerant. The invention also provides a preparation method. The synthesized EPDM rubber gasket has ageing resistance, long service life, good performance in the environment of high high-low temperature difference and excellent sealing and water stopping effects, can meet the requirements of assembled concrete tunnel linings of underground engineering, and is mainly applied to waterproof treatment at the joints among duct pieces during shield construction of subway tunnels.
Description
Technical field:
The present invention relates to the waterproof, seepage control field, particularly synthetic rubber high polymer waterproof material and preparation method thereof.
Background technology:
How the elastic sealing gasket of porous special cross section uses in the Continental Europe, and with moral, Ying Weizhu, France is quite a few.But also there is Japan to use, the domestic theoretical and engineering practice system of more sophisticated structure Design and Calculation that aspect the metro shield Tunnel Engineering, progressively forms, because subway will pass through the higher stratum of water content inevitably, therefore the shield tunnel waterproof is extremely important, in the existing market, the water-proof material that adopts between the section of jurisdiction is mainly based on Ethylene Propylene Terpolymer (EPDM), and the Ethylene Propylene Terpolymer gasket is the most reliable water-proof material of waterproof between the section of jurisdiction.The Ethylene Propylene Terpolymer gasket that the present invention has satisfied the market requirement need possess excellent mechanical property and the low requirement of compressing deformation simultaneously, by regulating auxiliary dosage, change the different trades mark, change vulcanization system, thereby solved the big problem of Ethylene Propylene Terpolymer gasket compressive set, make carbon black particle be adsorbed on the rubber molecular chain space uniformly by adding strengthening agent, dispersion agent, make the rubber free radical combine by mixing, sulfuration and form stable chemisorption with carbon black particle, cause intermolecular space to diminish, to reach the purpose of waterproof.
Summary of the invention:
For the shortcoming and defect that overcomes prior art the invention provides a kind of synthesis of ternary ethylene-propylene rubber(EPR) gasket, comprise by weight percentage:
40%～50% terpolymer EP rubber
30%～40% carbon black
1%～3% stearic acid
15%～25% softening oil
1% anti-aging agent
1%～3% vulcanizing agent and vulcanization accelerator.
Described terpolymer EP rubber is general terpolymer EP rubber, and wherein ethylene content is that the 50%～60%, the 3rd monomer content is 8%～10% by weight percentage.
Described carbon black is a high abrasion furnace black(HAF), and density is every cubic centimetre of 1.5～3.5 gram.
Described softening oil is selected from general whiteruss, naphthenic oil.
Described anti-aging agent is selected from 4010A, 4020.
Described vulcanizing agent and vulcanization accelerator are selected from sulphur, dicumyl peroxide or N-cyclohexyl-2-benzothiazole sulfonamide.
The present invention also provides a kind of method of synthesis of ternary ethylene-propylene rubber(EPR) gasket, and it comprises the steps:
Begin mixing processing after taking by weighing terpolymer EP rubber 40%～50%, carbon black 30%～40%, stearic acid 1%～3%, softening oil 15%～25%, anti-aging agent 1%, vulcanizing agent and vulcanization accelerator 1%～3% premix by weight percentage; Curing temperature is 160 ℃～180 ℃, and curing time is 5～15min.
It is to be main raw material(s) with the terpolymer EP rubber that the present invention adopts Ethylene Propylene Terpolymer gasket (being also referred to as sealing rod), add reactive systems, reinforcement system, preventing aging system, vulcanization system is after mill mixing is even, a kind of sealing material of final sulfidization molding, this can not only bring into play the original advantage of terpolymer EP rubber, its mechanical property and compression performance and surface property have also been improved simultaneously, therefore this product has good tensile strength, tension set, the compression permanentset, ageing-resistant performance etc., it is simple to prepare this water-proof material required equipment, manufacturing expense and energy consumption significantly reduce, unharmful substance discharging in preparation process is that a kind of preparation is simple, environmental protection and energy saving, waterproof material easy to use.
The invention has the advantages that:
A produces simple, and the cycle is short, and energy consumption is low;
The unharmful substance discharging belonged to environmentally friendly product during b produced;
The c product has good tension, tension set, compression permanentset, ageing-resistant performance, surface property and wear resistance.
The innovative point of sealing pad is to possess high tensile simultaneously, high elongation at tear and low compression permanentset.
Embodiment:
Example 1
Respectively with 1.14,1.17,1.20,1.23, add Banbury mixer behind the terpolymer EP rubber of 1.26KG carbon black and 1.5KG, 70g zinc oxide, 20g stearic acid, 1kg softening oil, 20g anti-aging agent premix, discharging behind mixing 10min under 30 ℃～50 ℃, rapid sheet down after adding 100g sulphur and promotor in two roller mills, vulcanize 5～15min down at 160 ℃～180 ℃ and make goods, it is as follows to measure product performance:
The performance of table 1 EPT rubber packing pad
Can see by table 1, when adding the 1.20kg carbon black as can be known, not only brought into play carbon black loading the original advantage of terpolymer EP rubber by regulating, also improved its mechanical property and compression performance and surface property, obtained having good tension, the product of tension set, the permanent change of compression, ageing-resistant performance.
Example 2
To add Banbury mixer behind 1.5kg ethylene content 50%, 55%, 60% terpolymer EP rubber and 1.2kg carbon black, 60g zinc oxide and 18g stearic acid, 1kg softening oil, the 20g anti-aging agent premix respectively, 30 ℃～50 ℃ mixing 10min dischargings down, rapid sheet down after adding 100g sulphur and promotor in two roller mills, vulcanize 5～15min down at 160 ℃～180 ℃ and make product, it is as follows to measure product performance:
The performance of table 2 EPT rubber packing pad
Different with the single auxiliary dosage of table 1 change is that the method that table 2 is taked to change the different trades mark (ethylene content) elastomeric material is sought best proportioning.
