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 and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

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

[0025] A. Forming the base layer: input the unrolled metal coil 1 and the polymer film 2 together between the two pressure 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 input between the two cooling rollers 6 along the vertical direction, and the foaming extruder 8 squeezes the foamed PE material between the two base layers, and heats them at 50°C~ At a temperature of 90°C, the two base layers and the foamed PE material are compounded tog...

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 board has the advantages of light weight, strong rigidity, good heat and sound insulation, etc., and these advantages are mainly realized by the numerous pores on the PE composite board. [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 opposite sides of the two base layers are respectively covered with protective films. Among them, the base layer is composed of a metal coil and a polymer film, and the base layer is compounded with the PE foam layer by melting the polymer film at a certain temperature. [0004] The existing compounding method of the base layer and the...
