Problems solved by technology

[0002] As a general-purpose resin, the traditional PVC material itself exhibits good mechanical properties and flame-retardant functions, but it immediately charcoalizes into powder or cracks when it encounters a flame and then falls off. The burned material has no mechanical strength at all and cannot maintain the original shape, which shorts the wires and speeds up burning

Abstract

The invention relates to a ceramic PVC material and a preparation method, and belongs to the technical field of plastic processing. In the case of high temperature and fire, the material rapidly formsa hard ceramic framework, continuously has the insulating property, can effectively prevent flame propagation of cables and secondary damage in the fire (obviously reduce harmful smoke), and can be widely applied to various fireproof materials. The preparation method comprises the following steps: (1), mixing and performing surface coupling modification treatment on a ceramic forming agent and ceramic forming padding at 60 DEG C in a high-speed mixer with the rotate speed being 200 to 800r / min; (2), putting PVC resin, a flame retardant, a heat stabilizer, a lubricant, an antioxidant and the ceramic forming agent and the ceramic forming padding subjected to coupling modification treatment into a kneader, kneading for 10min at 70 DEG C, pouring a plasticizer into the kneader, continuously kneading for 15min, and then taking out the materials for standby; (3), performing plastifying extrusion on the uniformly kneaded materials at 160 DEG C, and performing granulation, so as to obtain theceramic PVC material.

Description

Technical field [0001] The invention belongs to the technical field of plastic processing, and specifically relates to ceramicized PVC and a preparation method. Background technique [0002] As a general-purpose resin, the traditional PVC material itself exhibits good mechanical properties and flame-retardant functions, but it is immediately charred into powder or cracks and then falls when encountering a flame. The burned material has no mechanical strength at all and cannot maintain the original The shape short-circuits the wires and accelerates the burning. The decomposition products in the fire (such as hydrogen chloride, etc.) are likely to cause secondary damage. As a new type of polymer-based composite material, ceramic flame-retardant PVC material can maintain the inherent characteristics of PVC material at normal temperature. In the event of a fire, after high-temperature continuous combustion, a hard ceramic skeleton structure is quickly formed, which is not melted. I...
