Problems solved by technology

As far as foreign countries are concerned, the core technology of foam materials is also in the hands of a few large companies in a few countries. The main reason is that foam materials are crystalline polymers that hardly flow below the crystal melting point, but Above the melting point of crystallization, the viscosity of the melt decreases sharply, so the gas generated during the foaming process of the foaming material is difficult to be surrounded by the melt; in addition, a large amount of heat will be released when the foaming material changes from a molten state to a crystalline state. It takes a long time to change from melt to solid, and the production is usually realized by intermittent foaming, which limits its large-scale production
[0003] At present, extrusion technology and supercritical gas continuous foaming are used to prepare foamed materials, but because the supercritical gas is pumped into the screw through a high-pressure pump, and the feed port returns and leaks, the air pressure at the die is unstable. Poor foaming stability

Abstract

The invention discloses a foam extrusion processing device for architectural decoration. The foam extrusion processing device comprises an underframe, an extruder shell, a supporting seat, a storing tank and a high-pressure pump; the extruder shell is fixedly arranged on the base; the supporting seat is fixedly arranged on the upper side of the extruder shell; the bottom end of the storing tank isfixedly arranged on the supporting seat, the top end of the storing tank is provided with a feeding inlet, and the bottom end of the storing tank communicates with the interior of the extruder shellthrough a communicating pipe; an extrusion screw is rotatably arranged in the extruder shell through a bearing pedestal, and a foaming mold is fixedly arranged at the other end of the extruder shell;and a mixture of foaming powder and a small amount of water is contained in the storing tank, the foaming powder and the water enter the extruder shell from the communicating pipe in a pressure stabilizing state in a powder fluid mode, and a foaming material is quickly molten in a screw extruder and foamed with the water in a screw extruder mold port. Therefore, the defects that that material returning and gas leaking are prone to occurring when the foaming material is foamed in the screw are overcome.

Description

technical field [0001] The invention relates to the technical field of architectural decoration foam processing, in particular to a foam extrusion processing device for architectural decoration. Background technique [0002] As a new type of foamed plastic with high strength and good heat resistance, foaming material plays a huge role in the general trend of light weight and energy saving. Foaming materials Foaming products have good performance and application prospects, but the foaming of foaming materials is very difficult, and the relevant and industrialized core technology has not yet been mastered in China. As far as foreign countries are concerned, the core technology of foam materials is also in the hands of a few large companies in a few countries. The main reason is that foam materials are crystalline polymers that hardly flow below the crystal melting point, but Above the melting point of crystallization, the viscosity of the melt decreases sharply, so the gas ge...
