Abstract

The utility model discloses a compound plastic structure, which comprises a base layer and high-density plastic foaming layers, wherein the two surfaces of the base layer are covered with the high-density plastic foaming layers respectively. The utility model improves the physical rigidity of the surface of the compound plastic structure, so as to resist stronger impact force and friction force, has excellent shock-absorbing capacity, and reduces production cost as the plastics in the identical type are adopted for the base layer and the high density plastic foaming layers.

Description

The composite plastic structure

Technical field

The utility model relates to the plastic construction field, relates in particular to the low-density foamed layer of a kind of high foaming composite plastic structure mutually compound with the high density foaming layer.

Background technology

At present, considerable article shipment need be carried out auxiliary package to reach anti-extrusion, shock proof purpose by plastic foam.The plastic package material of Xiao Shouing is by the high foamed plastic of individual layer or many mutually compounded low density plastics's foams of the high foamed plastic of individual layer mostly on the market, this plastic foam is because every cubic metre lighter weight, density is low, cause its case hardness low, the physics poor rigidity, can not resist stronger impulsive force and frictional force, surface irregularity, easy to wear.

In existing composite plastic structure, a kind of structure at the gluing hard plastic layer in height foaming plastic layer both sides is arranged, though the physics rigidity of this body structure surface significantly improves, lifting along with compressive resistance, need constantly to increase the thickness of hard plastic layer to reach good compressive property, this can increase the weight of plastic package material undoubtedly, it is needed in light weight fundamentally to solve the composite plastic structure, the problem that the surface physics rigidity is good, simultaneously, the high foaming layer of this composite plastic structure is often adopted different plastics with the hard plastic layer, and cost is wayward.

The utility model content

Technical problem to be solved in the utility model is, a kind of composite plastic structure is provided, and can improve composite plastic Surface Physical rigidity, can resist stronger impulsive force and frictional force, has good shock-absorbing capacity.

In order to solve the problems of the technologies described above, embodiment of the present utility model provides a kind of composite plastic structure, comprises basic unit and high-density plastic's foaming layer, and described high-density plastic's foaming layer covers two surfaces of described basic unit respectively.

Described high-density plastic's foaming layer is connected with described basic unit is compound.

Every cubic metre quality of described high-density plastic's foaming layer is at 60kg-300kg.

Described high-density plastic's foaming layer is made by the low-density high-pressure polyethylene material.

A kind of composite plastic structure that the utility model embodiment is provided is in the compound high-density plastic's foaming layer of both side surface of the low-density foamed layer of height foaming, every cubic metre quality of high-density plastic's foaming layer is at 60kg-300kg, the basic unit of this composite plastic structure adopts the low-density foamed layer of high foaming, has good shock-absorbing capacity, high-density plastic's foaming layer has promoted the hardness on composite plastic surface, can resist stronger impulsive force and frictional force.

Description of drawings

Fig. 1 is the cross section structure schematic diagram of a kind of composite plastic structure of being provided of the utility model embodiment.

The specific embodiment

Below with reference to accompanying drawing preferred embodiment of the present utility model is described.

A kind of composite plastic structure that the utility model embodiment is provided comprises basic unit 1, high-density plastic's foaming layer 2, and described high-density plastic's foaming layer 2 covers two surfaces of described basic unit 1 respectively.

Referring to Fig. 1, basic unit 1 is made through foam process production by the low-density high-pressure polyethylene material, it comprises individual layer high foaming plastic layer or many high foaming of the mutually compounded multilayer of the high foaming of individual layer plastic layer plastic layers, and the quality that the high foaming of described individual layer plastic layer is every cubic metre is between 17kg-35kg.

High-density plastic's foaming layer 2 and 1 compound connection of described basic unit.

High-density plastic's foaming layer 2 is made by the low-density high-pressure polyethylene material.

In other embodiments of the utility model embodiment composite plastic structure, basic unit 1 can be that the high foaming of individual layer plastic layer also can be the mutually compounded multilayer foamed plastic layer of many individual layers high foaming plastic layer, as the two-layer individual layer high foaming mutually compounded basic unit 1 of plastic layer or three layers of mutually compounded basic unit 1 of individual layer high foaming plastic layer or the like, basic unit 1 does not limit the number of plies of the high foaming of individual layer plastic layer; High-density plastic's foaming layer 2 does not limit with the connected mode of described basic unit 1, is fixedly connected with described basic unit 1 as long as satisfy high-density plastic's foaming layer 2; The number of plies of high-density plastic's foaming layer 2 does not limit, can be that individual layer also can be a multilayer, as long as satisfy its quality of every cubic metre greater than basic unit's 1 quality of every cubic metre, preferred, every cubic metre quality of high-density plastic's foaming layer 2 is at 60kg-300kg; In addition, high-density plastic's foaming layer 2 also can use the outer other materials of low-density high-pressure polyethylene to make.

A kind of composite plastic structure that the utility model embodiment is provided is by the compound high-density plastic's foaming layer of both side surface at the low-density foamed layer of height foaming, when guaranteeing good shock-absorbing capacity, can resist stronger impulsive force and frictional force, generic plastic is adopted in basic unit and high-density plastic's foaming layer, can reduce production costs.

Above disclosed only is the utility model preferred embodiment, can not limit the interest field of the utility model certainly with this, and therefore the equivalent variations of being done according to the utility model claim still belongs to the scope that the utility model is contained.
