Foamed composite board and manufacturing method thereof

Abstract

The invention discloses a foamed composite board, which comprises a foamed core layer (1), wherein the foamed core layer consists of a composite material (2) and a foamed core plate (3), the foamed core layer (1) is a foamed-pass structure, the upper part of the composite material is provided with a color steel plate (4), and the pass structure of the foamed core layer (1) is respectively compounded with the color steel plate (4) and the composite material (2) through the hot melting way so as to form a foamed pass-structure composite board. The manufacturing method of the foamed composite board is characterized in that: under the situation that a certain foaming quality is realized, the entire compounding process is completed by utilizing the high temperature of the foamed core plate while the thickness of the composite board is increased, so the cost for manufacturing the composite board can be reduced; and the foaming quantity required for the production can be controlled according to the usage amount of the foaming agent and the stability of an extruding machine, so the sound insulation, the heat insulation and the light-weight effect of the foamed composite board can be improved.

Description

technical field [0001] The invention relates to a foamed composite board, in particular to a foamed composite board and a manufacturing method thereof. Background technique [0002] At present, the general foamed composite board uses its PE polyethylene as the base material. On the one hand, the composite board made of pure PE polyethylene has high cost and wastes materials. . [0003] Therefore, after research, various researchers found that adding relevant additives to PE particles, and then forming a foamed core material through hot melt foaming treatment, the foamed core material is widely used in airports, stations, subways, stadiums, shopping malls, Public places such as office buildings and high-end cultural and entertainment centers can play the role of sound insulation, heat insulation and heat insulation, but they cannot control the amount of foaming well. and other performance. SUMMARY OF THE INVENTION [0004] The technical problem to be solved by the presen...

Problems solved by technology

[0002] At present, the general foam composite board uses its PE polyethylene as the base material. On the one hand, the composite board made of pure PE polyethylene is costly and wastes materials. On the other hand, it is difficult to dispose of plastic products once they expire, which affects the living environment.

[0003] Therefore, after research, various scientific researchers found that adding relevant additives to PE particles, and then forming a foam core material through hot-melt foaming treatment, the foam core material is widely used in airports, stations, subways, stadiums, shopping malls, Although public places such as office buildings and high-end cultural and entertainment centers can play the role of sound insulation and heat insulation, they cannot control the amount of foaming well.
