Abstract

The invention provides a low heat conduction polystyrene heat insulation material, and belongs to the technical field of heat insulation materials. The low heat conduction polystyrene heat insulation material comprises, by weight, 100 parts of polystyrene, 0.1-10 parts of graphite, 6-15 parts of a foaming agent, and 1-15 parts of a fire retardant, wherein the average particle size of the graphite is 2000-5000 meshes. The low heat conduction polystyrene heat insulation material has the advantages of simple formula and easy large-scale automatic production. In the invention, the 2000-5000 mesh graphite is adopted as a nucleating agent to substitute traditional talcum powder, so the foaming efficiency is improved, and cells of the finished material are uniform, and the unit weight of foamed sheets made by using the material can be reduced to 28kg / m<3>, and the heat conduction coefficient of the sheets is 0.019-0.024W / (m.K). The thickness of the sheets made by using the material is 30% smaller than that of routine polystyrene extruded foamed heat insulation sheets on the premise of realizing a same heat insulation effect.

Description

technical field [0001] The invention relates to the technical field of thermal insulation materials, in particular to a polystyrene thermal insulation material with low thermal conductivity. Background technique [0002] Insulation materials can be divided into two categories: inorganic insulation materials and organic insulation materials according to their raw material composition. Inorganic thermal insulation materials have high thermal conductivity, large capacity, and difficult construction, so they are seldom used. Organic thermal insulation materials have low thermal conductivity, small bulk density, easy construction, and large-scale automatic production, so they have a wide range of applications. Polystyrene is a common organic thermal insulation material with good thermal insulation effect. [0003] Existing traditional polystyrene insulation materials use extrusion molding technology, use talcum powder as a nucleating agent, and use difluorochloroethane (HCFC142...
