Abstract

The invention belongs to the field of building materials, and particularly relates to a resource-conserving type gray plastic foaming polymer composite material. The invention also relates to a preparation method of the composite material. The invention has the technical scheme that the resource-conserving type gray plastic foaming polymer composite material comprises thermoplastic plastic polyvinyl chloride (PVC), filler coal ash, an auxiliary heat stabilizer, a coupling agent, a compound stabilizer, an inside and outside lubricating agent, a plasticizing accelerating agent, a general foaming agent and a foaming regulator. The resource-conserving type gray plastic foaming polymer composite material can be used for utilizing the coal ash with a high added-value in a reclamation way, thus not only saving a great deal of calcium carbonate and timber resources, but also reducing environmental pollution and protecting the human health.

Description

technical field [0001] The invention belongs to the field of building materials, in particular to a resource-saving gray plastic foamed polymer composite material. The present invention also relates to a method for preparing the above-mentioned composite material. Background technique [0002] Fly ash is the largest single emission source of industrial solid waste in my country. For many years, the fly ash of large, medium and small thermal power plants in China has not been efficiently utilized. In the past, traditional storage, burial and other disposal methods have caused serious damage to the environment and brought great harm to public health. At present, my country's fly ash is mainly used to produce concrete, fly ash bricks, cement and other products with low technical content and low added value, and the utilization rate and utilization efficiency are relatively low. Someone recently invented "a formula and preparation method of an environmentally friendly porcelai...
