Problems solved by technology

[0002] The construction process of polyamide-6 corrugated pipe is simple, has a certain degree of flexibility, and is not used for anti-corrosion treatment. The disadvantage is that it is not as good as steel pipe. Leakage causes damage, so it is necessary to continuously improve its surface strength, UV resistance, aging resistance, chemical corrosion resistance and other properties

Embodiment 1

[0045] 1) Take 90% by weight of polyamide-6 and put it into a reaction kettle, and heat to melt;

[0046] 2) Reactor is heated to 64 DEG C, put into 1% by weight heat stabilizer, then drop into 2% by weight of poly-a-methylstyrene resin and 1% by weight of terpene resin; stir for 4 hours, wait for another completely miscible;

[0047] 3) Put 1% by weight of nano-calcium carbonate into the reactor, adjust the temperature to 60° C., stir and disperse at 600 rpm for 3 minutes;

[0048] 4) 2% by weight of resin nano-cerium and 0.1% by weight of zinc oxide are put into the reactor, heated to 100° C., fed with 0.15% by weight of antioxidant, and stirred at 1000 rpm for 20 minutes;

[0049] 5) Continue stirring at a temperature of 120°C. After stirring evenly, it will be automatically cooled. After passing through the vibrating screen, the material will be automatically loaded. The twin-screw extruder will be extruded under high temperature and high pressure. After the product is pu...

Embodiment 2

[0053] 1) Put 100% by weight polyamide-6 into a reaction kettle, and heat until melting;

[0054] 2) Reactor is heated to 107 DEG C, put into 5% by weight heat stabilizer, then drop into 3% by weight of poly-a-methylstyrene resin and 4% by weight of terpene resin; stir for 6 hours, wait until completely miscible;

[0055] 3) Put 3% by weight of nano-calcium carbonate into the reactor, adjust the temperature to 65° C., stir and disperse at 1000 rpm for 5 minutes;

[0056] 4) 3% by weight of resin nano-cerium and 1.5% by weight of zinc oxide are put into the reactor, heated to 110° C., fed with 0.3% by weight of antioxidant, and stirred at 1600 rpm for 30 minutes;

[0057] 5) Continue to stir at a temperature of 150°C. After stirring evenly, it will be automatically cooled. After passing through the vibrating screen, the material will be automatically loaded. It will be extruded by a twin-screw extruder through high temperature and high pressure. After the product is pulled out...

Embodiment 3

[0061] 1) Take 95% by weight of polyamide-6 and put it into a reaction kettle, and heat it until it melts;

[0062]2) The reaction kettle is heated to 100°C, and 3 parts by weight of heat stabilizer are added, followed by 2.5% by weight of poly-a-methylstyrene resin and 4% by weight of terpene resin; stir for 6 hours, and wait until it is completely Miscible;

Abstract

The invention discloses a novel special material for rubber bellows.The novel special material for the rubber bellows is prepared from the raw materials in parts by weight: 2-3% of resin nano-cerium,0.1-1.5% of zinc oxide, 1-3% of nano-calcium carbonate, 1-5% of heat stabilizer, 90-100% of polyamide-6, 2-3% of poly a methylstyrene resin, 1-4% of terpene resin and 0.15-0.3% antioxidant. Compared with existing pipes, the pipes prepared by the preparation method of the novel special material for the rubber bellows has good strength, high anti-aging property, high radiation resistance, high oxidation resistance, good thermal stability and light stability; and the impact resistance of the pipes is greatly improved, the industry standards in many fields are met, the compatibility of various materials is effectively improved, the coating modification of the polyamide-6 is achieved, the mechanical properties of the polyamide-6 is improved, and the impact resistance and compressive propertiesof the finished bellows are improved.

Description

technical field [0001] The invention relates to the field of corrugated pipes, more specifically, a novel rubber corrugated pipe special material and a preparation method thereof. Background technique [0002] The construction process of polyamide-6 corrugated pipe is simple, has a certain degree of flexibility, and is not used for anti-corrosion treatment. The disadvantage is that it is not as good as steel pipe. Leakage causes damage, so it is necessary to continuously improve its surface strength, UV resistance, aging resistance, chemical corrosion resistance and other properties. Contents of the invention [0003] In order to make up for the above deficiencies, the present invention provides a new special material for rubber bellows and its preparation method. [0004] The scheme of the present invention is: [0005] A new special material for rubber bellows, made of raw materials including the following parts by weight: [0006] [0007] As a preferred technical...
