Anti-resonance sound insulation extruded sheet and extruded sheet manufacturing method

Abstract

The invention discloses an anti-resonance sound insulation extruded sheet and an extruded sheet manufacturing method, and belongs to the technical field of heat insulation materials. The anti-resonance sound insulation extruded sheet comprises, by weight, 150 to 185 parts of polystyrene particles, 20 to 38 parts of small black bead graphite heat preservation particles, 6 to 8 parts of graphite powder, 0.5 to 1.2 parts of a surfactant, 0.8 to 1.6 parts of a flame retardant, 2 to 5 parts of a catalyst and 4 to 8 parts of a foaming agent. According to the anti-resonance sound insulation extrudedsheet and the extruded sheet manufacturing method, a surfactant is added to modify graphite powder, by the specific inorganic material performance, a high-elasticity and high-strength protection layeris formed on the surface of the interconnection wall, the closed-cell honeycomb state structure is matched, the interconnection wall in each dimension space has the consistent thickness, the good anti-resonance effect and the good sound insulation effect are achieved, and the special molecular structure is high in compression resistance stability and creep resistance, capable of saving energy, environmentally friendly and high in permeation resistance.

Description

technical field [0001] The invention relates to the technical field of thermal insulation materials, in particular to an anti-resonance and sound-insulating extruded board and a method for manufacturing the extruded board. Background technique [0002] Extruded board is a material that is continuously extruded and foamed by a special process. The hard film formed on the surface is uniform and flat, and the internal completely closed-cell foam is continuous and uniform, forming a honeycomb structure, so it has high compressive resistance, light weight, and is durable. Water-absorbing, airtight, wear-resistant, and non-degradable. Compared with EPS polystyrene foam boards, its strength, heat preservation, and water vapor penetration resistance have been greatly improved. It can still maintain its heat preservation performance under water immersion conditions. and compressive strength, especially suitable for heat insulation, heat preservation, and moisture-proof treatment of b...

AI Technical Summary

Problems solved by technology

[0003] The object of the present invention is to provide an anti-resonance sound-insulating extruded board and a method for making the extruded board, so as to solve the above-mentioned background technology. Under normal use, the anti-resonance effect and sound insulation effect are poor, the stability is not strong, and the creep resistance is poor. At the same time, the slightly toxic gas emitted by its inorganic materials has poor permeability resistance.
