Ceramic bovine flame retardant polymer composite material and application thereof

Abstract

The invention provides a ceramic bovine flame retardant polymer composite material based on polyolefin or a thermoplastic polyurethane elastomer. The ceramic bovine flame retardant polymer composite material is prepared from the following components in parts by weight: 30-40 parts of polyolefin resin or the thermoplastic polyurethane elastomer, 25-45 parts of a ceramic forming filler, 20-30 parts of a halogen-free flame retardant, 1-5 parts of a flame-retardant synergist, 1-3 parts of a plasticizer, 0.5-2 parts of an antioxidant and 0.02-0.15 part of a crosslinking agent, wherein the ceramic forming filler is prepared from the following components including low softening point glass powder and a silicate mineral filler. The invention also provides application of the ceramic bovine flame retardant polymer composite material in the field of cables. According to the ceramic bovine flame retardant polymer composite material disclosed by the invention, a dense ceramic bovine product can be formed within a range from 600 DEG C to 1000 DEG C, and the formed ceramic bovine product is good in high-temperature strength and flame retardancy and is also good in mechanical properties under room temperature.

Description

technical field [0001] The invention belongs to the field of refractory materials, and in particular relates to a ceramizable flame-retardant polymer composite material. technical background [0002] Chinese patent CN1095181 uses mica tape, non-combustible silicon coating and PVC / lanthanum oxide / cerium oxide mixed plastic to make a high fire-resistant cable with high fire resistance, high temperature resistance, low smoke and no halogen when burning. The disadvantage of this patent is that the cost is high and there is no porcelain-forming property. Chinese patent CN101169993 adopts fire-resistant inorganic fiber heat insulation material and silicon-based elastomer composite material to make heat-insulated fire-resistant cables. The disadvantage of this patent is that the cost is high and there is no porcelain-forming property. Chinese patent CN1480958 uses mineral expansion material to make heat-insulated and fire-resistant cables, which can withstand 750 o Under C flame...

AI Technical Summary

Problems solved by technology

The disadvantage of this patent is that the strength of the formed ceramics is poor, the temperature required for the formation of ceramics is high, and the mechanical properties of the cable material are poor.

[0003] In short, in the prior art, the disadvantages of refractory polymer composite materials are narrow application range, high cost, poor strength of the formed ceramics, high temperature required for porcelain formation, and poor flame retardant effect
