Abstract

The invention relates to the field of PVC material flame retardants and in particular relates to a flame retardant smoke suppressant of a PVC (polyvinyl chloride) material, a preparation method and an application of the flame retardant smoke suppressant. The flame retardant smoke suppressant of the PVC material is composed of the following components in parts by weight: 2-15 parts of aluminium hydroxide, 0.5-5 parts of ammonium octamolybdate, 0.5-4 parts of zinc borate, 0.5-5 parts of zinc molybdate, 0.5-4 parts of zinc oxide and 0.01-0.10 part of stearic acid. The flame retardant smoke suppressant has the advantage that the purpose of flame retardant smoke suppression with fewer materials is basically achieved by the synergistic effect among each component of the flame retardant smoke suppressant. In addition, the PVC material adopting the flame retardant smoke suppressant has good flame retardant performance and excellent resistance tobacco control performance so that casualties and property losses can be greatly reduced in a fire accident.

Description

technical field [0001] The invention relates to the flame retardant field of PVC materials, in particular to a flame retardant and smoke suppressant for PVC materials and its preparation method and application. Background technique [0002] Polyvinyl chloride (PVC) is one of the five general-purpose plastics, and it is widely used in various fields because of its excellent performance-price ratio. In recent years, as the country vigorously promotes the tendency of replacing steel with plastic and wood with plastic, PVC as a chemical building material has developed rapidly. However, PVC is a flame retardant material, but due to the need to add plasticizers during processing, the flammability of PVC is improved, and a large amount of smoke will be generated when its products are burned, which increases the harm of fire to people's lives and property . With the development of society, people's requirements for materials have become more and more stringent. Ordinary PVC materi...
