Problems solved by technology

But there is a problem with this method: the two cooling rollers are distributed on the upper and lower sides of the base layer, which will squeeze the PE foam layer to a certain extent, which will easily lead to the rupture of the cells in the PE foam layer, and the rupture of the cells will lead to compounding. Various performance failures of the board

Embodiment Construction

[0023] The following are specific embodiments of the present invention in conjunction with the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0024] Such as figure 1 with figure 2 As shown, the processing technology of the PE foamed metal composite board includes the following steps:

[0025] A. Forming the base layer: the unwinded metal coil 1 and the polymer film 2 are fed into the two pressing rollers 5 for high-temperature pressing to form the base layer, wherein the pressing temperature is controlled at 150°C to 200°C;

[0026] B. Vertical compounding: The two base layers are fed between the two cooling rolls 6 in the vertical direction, and the foaming extruder 8 squeezes the foamed PE material into between the two base layers, and the temperature is at 50℃~ The two base layers and the foamed PE material are compounded together at a temperature of 90°C;

[0027] The po...

Abstract

The invention provides a processing technology of a PE (polyethylene) foamed metal composite plate, belongs to the technical field of machinery, and solves the problem that the existing processing technology is low in forming quality. The processing technology of the PE foamed metal composite plate comprises the following steps: A, base layer forming; B, vertical compounding; C, steering; D, flattening; E, film laminating; F, deburring; G, cutting. The processing technology of the PE foamed metal composite plate has the advantage of improving the forming quality.

Description

Technical field [0001] The invention belongs to the technical field of machinery, and relates to a PE foamed metal composite board, in particular to a processing technology of a PE foamed metal composite board. Background technique [0002] PE foamed metal composite panel has the advantages of light weight, strong rigidity, good heat and sound insulation, etc., and these advantages are mainly realized by the countless pores in the PE composite panel. [0003] Such as figure 1 As shown, the existing PE foamed metal composite board includes two base layers arranged above and below and a PE foam layer located between the two base layers, and the two base layers are respectively covered with protective films on opposite sides. Among them, the base layer is composed of a metal coil and a polymer film, and the base layer is combined with the PE foam layer by melting the polymer film at a certain temperature. [0004] The existing composite method of the base layer and the PE foam layer is...
