Abstract

The utility model discloses a pearl is cotton, including the pearl is cotton body, locate the aluminium foil layer of pearl is cotton body surface, this bulk recombination of pearl is cotton has the one deck to strengthen the stratum reticulare. The utility model discloses simple structure, easily make, have the intensity height, advantages such as toughness is good, the material is light, anti -seismic performance is good, shock -resistant, long service life, but the wide application is packed in multiple trade.

Description

A kind of expanded polyethylene foam

Technical field

The utility model relates to plastic cement packaging material, is specifically related to a kind of expanded polyethylene foam.

Background technology

Expanded polyethylene foam is that polyethylene foam is cotton, and being non-crosslinked hole-closing structure, also known as EPE pearl wool, is a kind of packaging material of novel environment friendly.It produces countless separated foams by low density polyethylene (LDPE) fat through physical blowing and forms, overcome common foamed glue frangible, distortion, restorative difference shortcoming.Due to expanded polyethylene foam there is water proof protection against the tide, shockproof, sound insulation, insulation, the plurality of advantages such as plasticity is good, toughness is strong, reconstituted circularly, environmental protection, crashworthiness power are strong, also there is good chemical resistance, be widely used in the packaging of the multiple product such as inner packing, commodity of the high-grade frangible gift wrap such as automobile cushion, boudoir, electronic apparatus, instrument and meter, computer, sound equipment, medicine equipment, industry control cabinet, hardware and lamp decoration, handicraft, glass, pottery, household electrical appliances, spraying, furniture family property, drinks and resin, hardware, toy, melon and fruit, leather shoes.After adding colored antistatic agent and fire retardant, the performance of its brilliance more aobvious.The good interior finish material in expanded polyethylene foam or various vehicle and room, expanded polyethylene foam, without anti-ultraviolet property, knows from experience the injury caused to people.

China's application number is the utility model of 2014203990422, and disclose a kind of expanded polyethylene foam of antiultraviolet, comprise expanded polyethylene foam body, expanded polyethylene foam body surface is compounded with one deck aluminium foil layer, and expanded polyethylene foam body and aluminium foil layer are formed by Rolling compund.Compared with traditional expanded polyethylene foam, this utility model is by metallized film and expanded polyethylene foam compound, there is good anti-uv-ray, but still there is following defect: one, expanded polyethylene foam does not arrange more protection device, and because EPE pearl wool material is frivolous, intensity is low, poor toughness, very easily compressive deformation and fragmentation, impact uses; Its two, because the material of EPE pearl wool own is frivolous and be set to single structure, damping performance is poor, not shock-resistant.

Utility model content

For the deficiency that prior art exists, the utility model provides that a kind of intensity is high, good toughness, the expanded polyethylene foam of not yielding fragmentation.

In order to achieve the above object, the technical scheme taked of the utility model:

A kind of expanded polyethylene foam, comprises expanded polyethylene foam body, is located at the aluminium foil layer of expanded polyethylene foam body outer surface, is compounded with one deck and strengthens stratum reticulare in described expanded polyethylene foam body.

As optimal technical scheme, in order to ensure intensity, the toughness of expanded polyethylene foam, effectively control the weight of true topic, described reinforcement stratum reticulare is plastics stratum reticulare, described plastics stratum reticulare and expanded polyethylene foam calor innatus integrator simultaneously.

As optimal technical scheme, in order to improve integral shock-absorbing performance and the impact strength of expanded polyethylene foam, effectively prevent connection with wrapping of piece damaged, described aluminium foil layer is inboard and be coated with a thin layer around expanded polyethylene foam body outer surface, forms a cooling combined layer between described thin layer and expanded polyethylene foam body.

Compared with prior art, the beneficial effect that has of the utility model:

1, be compounded with one deck in expanded polyethylene foam body and strengthen stratum reticulare, improve intensity and the toughness of expanded polyethylene foam, effectively prevent expanded polyethylene foam compressive deformation and fragmentation, increase the service life.

2, the reinforcement stratum reticulare of plastics is set, and plastics stratum reticulare and this thermal synthesis of expanded polyethylene foam one, improve intensity and the toughness of expanded polyethylene foam further, ensure the slight of expanded polyethylene foam simultaneously.

3, thin layer is set, and between thin layer and expanded polyethylene foam body, forms a cooling combined layer, improve integral shock-absorbing performance and the impact strength of expanded polyethylene foam, effectively prevent connection with wrapping of piece damaged.

4, the utility model structure simple, be easy to realize, and long service life.

Accompanying drawing explanation

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

Fig. 1 is structural representation of the present utility model;

Drawing reference numeral: 1, expanded polyethylene foam body, 2, strengthen stratum reticulare, 3, thin layer, 4, cooling combined layer chamber, 5, aluminium foil layer.

Detailed description of the invention

A kind of specific embodiment of the utility model is proposed as shown in Figure 1, a kind of expanded polyethylene foam, comprise expanded polyethylene foam body 1, be located at the aluminium foil layer 5 of expanded polyethylene foam body 1 outer surface, the present embodiment preferably arranges expanded polyethylene foam body 1 external surface peripheral and is positioned at aluminium foil layer 5 inboard and is coated with a thin layer 3, a cooling combined layer 4 is formed between described thin layer 3 and expanded polyethylene foam body 1, the integral shock-absorbing performance of effective raising expanded polyethylene foam and impact strength, effectively prevent connection with wrapping of piece damaged.

Be compounded with one deck in described expanded polyethylene foam body 1 and strengthen stratum reticulare 2, it is plastics stratum reticulare that the present embodiment preferably arranges reinforcement stratum reticulare 2, and described plastics stratum reticulare 2 and expanded polyethylene foam body 1 thermal synthesis one, ensure intensity, the toughness of expanded polyethylene foam, improve overall performance, effectively control overall weight simultaneously.

Certainly; just by reference to the accompanying drawings the preferred detailed description of the invention of the utility model is described in detail above; not limit practical range of the present utility model with this; all equivalence changes done according to principle of the present utility model, structure and structure, all should be covered by protection domain of the present utility model.
