Abstract

The invention relates to the technical field of PVC materials and particularly relates to a low-smoke flame-retarding ceramizable PVC material, a preparation method and an application thereof. The PVC material includes, by weight, 20-80 parts of PVC resin, 20-60 parts of a plasticizer, 10-30 parts of a flame retardant, 1-10 parts of a smoke inhibitor, 20-80 parts of a ceramization powder, 0.5-5 parts of a compatilizer, 0.02-0.1 parts of an anti-ultraviolet agent, and 0.02-0.1 parts of an antioxidant. The PVC material has excellent flame-retarding effect, low smoke density, high strength, good flexibility and high break elongation, can form a compact ceramized product at the temperature range of 600-1000 DEG C, is low in ceramization temperature and can form compact ceramic. The formed ceramized product has high high-temperature strength and anti-heat-flow-impact capability.

Description

technical field [0001] The invention relates to the technical field of PVC materials, in particular to a low-smoke flame-retardant ceramizable PVC material and a preparation method and application thereof. Background technique [0002] With the continuous progress of social development, people's requirements for safety protection continue to increase. In the field of wire and cable, people have higher and higher requirements for the continuous power supply capability of fire-resistant power cables in fires. The insulation performance of fire-resistant power cables has an important impact on their continuous power supply capabilities in fires. [0003] The ceramizable polymer composite material is a new type of heat-resistant material, which is a composite material prepared by adding ceramizable additives to polymer / resin and melt blending. The ceramizable polymer composite material has excellent high and low temperature resistance, electrical insulation, ozone resistance, w...
