Problems solved by technology

[0002] At present, the decorative panels used for automotive interior parts are all made of hemp felt panels, GMT panels, PP wood powder panels, MDF, etc., through secondary hot pressing molding or artificial pasting to complete the decorative surface PVC and non-woven fabrics The hot-press compounding and manual pasting compounding, the secondary processing not only increases the processing cost of the decorative parts, but also requires a large investment in the processing press and flat mold, and the plate is prone to warping and deformation due to temperature changes after processing and compounding. And the surface of MDF is prone to mildew when it is damp

Abstract

The invention discloses a PP (Propene Polymer) fiber composite board and a production method. The PP fiber composite board comprises a substrate layer (1) and a surface layer (2) and is prepared by the following steps: melt and cured materials of the substrate layer (1) and the surface layer (2) pass through a double-layer co-extrusion distributor to reach a die head which completes the extrusion of the PP fiber board; the composite formation of surface leather texture and non-woven fabrics of the extruded materials are completed through three rollers; and the board is cooled, drawn, cut and packaged. The PP fiber composite board is less vulnerable to damp mildew and never warps; and furthermore, the PP fiber composite board is low in production cost and reliable in quality.

Description

technical field [0001] The invention specifically refers to a PP fiber composite board and a production method. Background technique [0002] At present, the decorative panels used for automotive interior parts are all made of hemp felt panels, GMT panels, PP wood powder panels, MDF, etc., through secondary hot pressing molding or artificial pasting to complete the decorative surface PVC and non-woven fabrics The hot-press compounding and manual pasting compounding, the secondary processing not only increases the processing cost of the decorative parts, but also requires a large investment in the processing press and flat mold, and the plate is prone to warping and deformation due to temperature changes after processing and compounding. And the surface of MDF is prone to mildew when it is damp. In addition, with the rapid development of the automobile industry, more and more scraps are produced in the processing of automotive interior parts. There is no good recycling metho...
