Abstract

The utility model relates to a fiber reinforced polystyrene micro-foaming multi-layer common-squeezing material which comprises four layers of layer structures and is characterized in that the four layers of layer structures are composed of a fiber reinforced polystyrene foaming core layer, a polystyrene-ethylene-butane-polystyrene linear triblock copolymer flexible gradient layer, a high impact polystyrene structure sizing layer and a decoration layer which are sequentially arranged from inside to outside, and the fiber reinforced polystyrene micro-foaming multi-layer common-squeezing material comprises the layer structures. The fiber reinforced polystyrene micro-foaming multi-layer common-squeezing material has the advantages that the overall density of the polystyrene micro-foaming wood-like material is low, however, the mechanical strength of the polystyrene micro-foaming wood-like material can satisfy the requirement of usage, and the recycling of polystyrene is facilitated.

Description

The multi-layer co-extruded section bar of the little foaming of a kind of fiber reinforcement polystyrene

Technical field

The utility model relates to the multi-layer co-extruded section bar of the little foaming of a kind of fiber reinforcement polystyrene.

Background technology

Series of advantages such as the little foaming wood-imitating type of polystyrene material has that light weight, price are low, insect protected, mothproof, moisture-proof, asepsis environment-protecting, long service life.Be widely used in places such as photo frame, picture frame, home decoration material.But because polystyrene has passed through little foam process, density is in case less than 0.5g/cm ³About; The mechanical property of section bar will descend very big; Do not reach the using property data of product, in order to overcome this shortcoming, therefore demand urgently developing the more little foaming wood-imitating type of high mechanical properties polystyrene material can be arranged; The utility model has passed through in sandwich layer to add fiber with the mechanical property that improves section bar, solves at present to utilize polystyrene to reclaim existing problem in little foamed profile of plastics.

Summary of the invention

The purpose of the utility model is that the existing density of the little foaming wood-imitating type of polystyrene material is lower than 0.5g/cm in the solution prior art ³The time section bar mechanical property decline to a great extent, do not reach the problem of the using property data of product, provide the little foaming of a kind of fiber reinforcement polystyrene multi-layer co-extruded section bar.The utility model designs the multi-layer co-extruded section bar of the little foaming of a kind of fiber reinforcement polystyrene; Comprise four shape structures layer by layer; It is characterized in that: be followed successively by fiber reinforcement foamed polystyrene sandwich layer, the flexible gradient layer of polystyrene-ethene-butylene-polystyrene linear three block copolymer, high impact polystyrene structure setting layer, decorative layer from inside to outside, have layer structure.The global density that the utility model has the advantages that the little foaming wood-imitating type of polystyrene material is low, but its mechanical strength can satisfy the requirement in the use, can promote polystyrene to recycle.

Description of drawings

Accompanying drawing is the section of structure of the utility model.

The specific embodiment

Comprise four shape structures layer by layer among the figure; It is characterized in that: be followed successively by fiber reinforcement foamed polystyrene sandwich layer 1, the flexible gradient layer 2 of polystyrene-ethene-butylene-polystyrene linear three block copolymer, high impact polystyrene structure setting layer 3, decorative layer 4 from inside to outside, have layer structure.

It is 20 ~ 30 fiber (based on the polystyrene meter) that its sandwich layer contains 3 ~ 8% equally distributed draw ratio, and it is the main part that constitutes product; Flexible gradient layer is polystyrene-ethene-butylene-polystyrene linear three block copolymer; The structure setting layer is a high impact polystyrene, and can stamp background color, confirms the dominant hue of product; Decorative layer is the abundant thermal transfer ink layer of one deck color.The utility model has passed through in sandwich layer, to add fiber to improve the mechanical property of section bar.

Claims

1. multi-layer co-extruded section bar of the little foaming of fiber reinforcement polystyrene; Comprise four shape structures layer by layer; It is characterized in that: be followed successively by fiber reinforcement foamed polystyrene sandwich layer (1), the flexible gradient layer (2) of polystyrene-ethene-butylene-polystyrene linear three block copolymer, high impact polystyrene structure setting layer (3), decorative layer (4) from inside to outside, have layer structure.
