Description
PREPARATION METHOD OF ETHYLENE PROPYLENE RUBBER (EPR) POWDER-BASED ETHYLENE-VINYL ACETATE (EVA) ANTI-AGING THERMOPLASTIC ELASTOMER (TPE) SEAL FOR WATER PIPE
TECHNICAL FIELD
100011 The present disclosure relates to the technical field of polymer material preparation, in particular to a preparation method of an ethylene propylene rubber (EPR) powder-based ethylene-vinyl acetate (EVA) anti-aging thermoplastic elastomer (TPE) seal.
BACKGROUND ART
[0002] Thermoplastic elastomers (TPEs) play an increasingly important role in the application of rubber products, resulting in a significantly increased demand. To reduce the cost of TPEs, increase the recycling of waste tires, and promote the promotion and application of TPEs, people have researched and developed rubber powder-based thermoplastic elastomers (RPTPEs). The RPTPE is prepared by blending rubber powder and thermoplastic resin, with simple processing and low processing cost; in addition, the rubber powder has a low cost and large dosage (generally accounting for 50% to 90% of a total mass), thereby greatly reducing the cost of the TPEs. Moreover, the rubber powder can be made from waste tires, which provides a new way to solve "black pollution" caused by the waste tires; furthermore, the TPEs can be recycled and are in line with the sustainable development path in China. Therefore, the RPTPEs have a desirable development prospect.
[0003] At present, the RPTPEs have poor mechanical properties, poor performance stability, and high cost during production, and are not suitable for making high-end products due to a strong smell.
SUMMARY
[0004] A purpose of the present disclosure is to provide a preparation method of an EPR powder-based EVA anti-aging TPE seal. The seal has a low cost and excellent performance. [0005] To achieve the above purpose, the present disclosure provides a preparation method of an EPR powder-based EVA anti-aging TPE seal, where the seal is prepared by the following raw materials in parts by weight: [0006] 15 parts to 20 parts of an EVA copolymer, [0007] 10 parts to 20 parts of a ci s-1,4-pol ybutadiene (cis-1,4-PB) rubber, [0008] 60 parts to 70 parts of a waste EPR powder, 100091 2.0 parts of a regeneration activator 510, 100101 15.0 parts of pine tar, [0011] 0.8 parts to 1.3 parts of a compatibilizer, [0012] 0.3 parts of a vulcanizer, [0013] 5.0 parts of zinc oxide, 100141 0.3 parts of stearic acid, and 100151 0.3 parts of an antioxidant 1010, and 100161 the preparation method includes the following steps: 100171 step 1), conducting activation on the waste EPR powder at 200°C for 30 min; [0018] step 2), conducting plastication on the cis-1,4-PB rubber for 5 min at room temperature to obtain a plasticated cis-1,4-PB rubber, uniformly dispersing an activated waste EPR powder obtained in step 1) and the EVA copolymer in a kneader to obtain a dispersion system, adding the dispersion system into the plasticated cis-1,4-PB rubber at 160°C ± 5°C, adding the regeneration activator and the pine tar, and mixing evenly to obtain a composite plasticated rubber; and [0019] step 3), adding the composite plasticated rubber, the vulcanizer, the compatibilizer, the zinc oxide, the stearic acid, and the antioxidant 1010 to a twin-screw extruder at 180°C, dispersing evenly, conducting a cross-linking reaction by a dynamic cross-linking system and a strong mechanical shear stress to obtain an EPR powder-based EVA TPE seal for a water pipe, and conducting mold pressing to obtain sheets.
100201 Preferably, the waste EPR powder may have a particle size of greater than or equal to 100 mesh.
[0021] Preferably, the EVA copolymer may be a granular solid.
100221 Preferably, the vulcanizer may be sulfur.
100231 Preferably, the compatibilizer may be di-tert-butyl dicumyl peroxide.
[0024] Compared with the prior art, the present disclosure has the following beneficial effects: [0025] (1) The EPR powder-based EVA anti-aging TPE seal for a water pipe has a tensile strength up to 10.5 IVIPa, an elongation at break up to 778%, and a Shore hardness up to 54 to 59; the TPE has a compression set of 17.90% to 24.53% and a water resistance of 2.28% to 4.12%; and the TPE has a hardness change in aging resistance and thermal oxidation aging resistance of +1 to +5, a strength change rate of -4.85% to 5.69%, and elongation change rate of 4.66% to 11.18%, an excellent ozone aging resistance, and no cracks.
[0026] (2) An activated EPDN4 rubber powder of 100 mesh and above is used; the fine EPR powder of more than 100 mesh is easier to disperse evenly than the EPR, the EVA and the cis1,4-PB rubber, and is not easy to stick to the screw during the dynamic cross-linking, without pollution. The EPR powder-based EVA TPE seal for a water pipe has an excellent comprehensive performance.
[0027] (3) The easily dispersible property of waste rubber powder is fully utilized to solve the environmental pollution caused by waste EPR being directly discarded, and the waste EPR is turned waste into treasure; a raw material cost is reduced by 45% to 55%, a profit of EPDM RP/EVA TPE is increased by not less than 100% compared to that of EPDM/EVA TPE
