Problems solved by technology

However, the rubber and plastic materials prepared simply with CPE plus inorganic fillers have high strength and high hardness, but this is solved by adding a large amount of plasticizers. Due to the migration of plasticizers, it also brings The decline in the long-term performance of this type of material

Embodiment Construction

[0016] The present invention will be further described in detail below in conjunction with embodiments.

[0017] Examples.

[0018] The preparation method of CPE / SBS / PET blended composite material is as follows:

[0019] Take the following parts by weight of raw materials: 70 parts of CPE, 30 parts of SBS, 15 parts of modified PET, 6 parts of dibutyl phthalate, 25 parts of semi-reinforcing carbon black, 20 parts of activated calcium carbonate, modified attapulgite 15 parts, 6 parts of dicumyl peroxide, 3 parts of ammonium polyphosphate, 2 parts of tribasic lead sulfate, 3 parts of magnesium oxide, 2 parts of zinc oxide, 15 parts of waste oil residue, 0.3 parts of accelerator TMTD, promotion 0.8 parts of DM, 1.5 parts of ODA, and 168 2 parts of antioxidant.

[0020] Wherein, the chlorine content of the CPE is 35%; the vinyl content of the SBS is 78%; the modified PET is prepared by the following method: weighing a certain amount of PET, TPU, and modified nano SiO 2 , Placed in a ...

Abstract

The invention discloses a chlorinated polyethylene / styrene-butadiene-styrene block copolymer / polyethylene terephthalate (CPE / SBS / PET) blending composite material, which comprises the following raw materials according to parts by weight: 70-80 parts of chlorinated polyethylene (CPE), 20-30 parts of styrene-butadiene-styrene block copolymer (SBS), 10-20 parts of modified polyethylene terephthalate (PET), 5-10 parts of dibutyl phthalate, 20-30 parts of semi-reinforcing carbon black, 10-20 parts of active calcium carbonate, 10-15 parts of modified attapulgite, 5-8 parts of dicumyl peroxide, 2-4 parts of ammonium polyphosphate, 2-3 parts of lead sulfate tribasic, 2-3 parts of magnesium oxide, 1-2 parts of zinc oxide, 10-20 parts of waste oil residue, 0.1-0.3 part of accelerant TMT, 0.5-1 part of accelerant DM, 1-2 parts of anti-aging agent ODA and 1-2 parts of antioxidant 168. In comparison with pure CPE, the CPE / SBS / PET blending composite material has the characteristics that 1, ozone resistance, weather aging resistance, high / low-temperature resistance and other performances are remarkably improved; 2, tensile strength, stress at definite elongation, tear resistance, heat resistance, flame resistance, fatigue resistance and rub resistance are improved; 3, oil resistance, fuel resistance, chemical resistance and other performances are enhanced; and 4, extrusion performance and drawability are improved, and meanwhile, the sizing material is not easy to self-vulcanize, so the storage stability is enhanced.

Description

Technical field [0001] The invention relates to a rubber-plastic material, in particular to a CPE / SBS / PET blended composite material and a preparation method thereof. Background technique [0002] CPE (chlorinated polyethylene) is a new type of modified material. It is the product of partial hydrogen atoms on the polyethylene molecular chain replaced by chlorine atoms. CPE with a chlorine content of about 35% is a thermoplastic elastomer. Its characteristics are It has high strength and dimensional stability without vulcanization, and can be filled with a large amount of inorganic fillers, so it has a wide range of applications in various rubber and plastic materials. However, the rubber and plastic materials prepared by simply using CPE and inorganic fillers have higher strength and hardness, but this is solved by adding a large amount of plasticizers. Due to the migration of plasticizers, The long-term performance of this type of material declines. Due to its good compatibili...
