Cross-linking low-smoke halogen-free and flame-retardant POE and preparation method thereof

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.
