Abstract

A preparing method of an environment-friendly inflaming retarding, smoke-inhibiting shaping phase-changing material is provided, comprising the following steps: adding the modified nanometer magnesium hydrate 100 parts, macromolecule elastomer 60-100 parts and flame retardant 1-10 parts to the refining machine to prepare the pre-mixing material under the conditions that the temperature is 50-15- centigrade and the rotating speed is 20-100 rpm; adding the phase-changing energy-saving material 50-100 parts under 20-70 phase-changing temperature to the pre-mixing material; continuing to refine the phase-changing material for 15-60 min to obtain the mixture; the parts above are all quality parts; filling the mixture to the mold and thermally-pressing the mixture by the vulcanizing press to form the plate material; after cooling to cross link by the high energy electronic beams. The phase-changing material and the modified nanometer magnesium hydrate are enveloped in the cross-linking net structure formed by the macromolecule elastomer, forming the inflaming retarding, self-extinguishing and smoke-inhibiting shaping phase-changing material; the phase-changing material enveloping rate of the product reaches 95-99%; the oxygen index reaches 23-28; the inflaming retarding performance is great; no toxic substance occurs wile burning the material, which can not generate the secondary pollution to the environment.

Description

technical field [0001] The invention belongs to the technical field of phase change energy storage materials, in particular to a shaped phase change energy storage material with good flame retardancy and smoke suppression performance and a preparation method thereof. Phase change energy storage material, the phase change energy storage material has obvious flame retardant effect, low smoke generation during combustion, no toxic and harmful gas, no harm to human body and environment, and meets environmental protection requirements. Background technique [0002] Affected by the ever-intensifying energy crisis since the 1980s, with the depletion of some resources, human beings have gradually realized the limitation and non-renewability of traditional resources, and are developing new energy sources (such as the development and utilization of marine resources) At the same time, research work on high-efficiency energy-saving technologies and renewable and environmentally friendly...
