Embodiment Construction

[0020] Specific examples of the present invention 1-3 cross-linked flame retardant POE elastomer components are as follows:

[0021]

[0022] The one-step preparation method of the present invention is as follows:

[0023] After mixing the silane crosslinking agent, peroxide initiator and crosslinking aid, put them into the high-speed kneader at one time with POE and EVA, 120°C for 20 minutes, and banbury at 95-100°C for 5 minutes Add nano-treated calcined clay, then add lubricant and processing oil, etc., continue banburying for 3 minutes, then add coupling agent, and banbury for 2 minutes before unloading. Thin pass the rubber material after banburying on the mill for three times at 18 o'clock, then make five triangular bags, pass it five times, then roll the strips or cool and granulate; or pass the rubber material after banburying through a single Extrusion and granulation by screw extruder or double-stage extruder, the temperature of each zone is: feed zone 120°C, 125...

Abstract

The invention relates to a water-producing natural cross-linking low-smoke halogen-free and flame-retardant POE (polyolefin elastomer) and a preparation method thereof. The POE comprises the following components in parts by weight: 80-90 parts of POE, 10-20 parts of polyolefine, 20-30 parts of calcined argil, 0.5-1 part of antiager, 0.1-1 part of peroxide initiator, 2-5 parts of silicane cross-linking agent, 0.1-1 part of cross-linking assistant, 2-10 parts of water-producing agent, 0.5-1 part of coupling agent, 5-10 parts of lubricant, 30-50 parts of processing oil and 80-100 parts of flame retardant. With the adoption of the water-producing cross-linking low-smoke halogen-free and flame-retardant POE and the preparation method thereof, the technical problem that silicane cross-linking cannot be conducted by the POE prepared in the prior art is overcome, and a water-producing natural cross-linking POE material with more excellent performance can be prepared, cables or accessories with excellent production performance can be produced, and the technical problems of production flow and energy waste can be solved.

Description

technical field [0001] The invention relates to a cross-linked low-smoke halogen-free flame-retardant POE elastomer and a preparation method thereof. Background technique [0002] Cross-linked flame-retardant POE elastomers can be widely used in molded products of flexible cables and cable accessories. Various excellent properties can still be maintained in the temperature range. Cross-linked flame-retardant POE elastomer not only has excellent physical and mechanical properties, electrical insulation properties, high temperature and cold resistance, but also has excellent water resistance, flexibility, impact resistance and so on. Therefore, the various excellent properties of cross-linked flame-retardant POE elastomers still have a wide range of development space. [0003] The types of POE used in cross-linked flame-retardant POE elastomers range from ordinary low modulus to high modulus. They can be used in low-voltage, soft and moving cables according to their differen...
