Description
Technical field
The present invention relates to a kind of compound sofa cushion of luffa-polyethylene multilayer and preparation method thereof, belongs to furniture and makes skill
Art field.
Background technology
Natural plant fiber material extensively should with the advantage such as its aboundresources, renewable, nontoxic, pollution-free, degradable
For in people's daily life articles for use；Luffa is that ripe sponge gourd fruit removes the fiber endoplasmic reticular knot obtained after crust and seed
The natural vascular tissue of structure, the appearance of luffa is in oval tubular or spindle shape, is about 30~65cm, diameter about 8~12cm；
Luffa is the three-dimensional porous mesh being interwoven by multilayer filiform fiber aspect, have body is light, matter is tough, it is wear-resisting, rich in bullet
The natural characteristics such as property, visible 3~4 cavitys in cross section, luffa is as a kind of green renewable resource, its unique lightweight
Porous three-dimensional net structure and excellent comprehensive performance, make it increasingly hew out brand-new and wide application in association area empty
Between.
Luffa is used for Sofa mattress or back cushion directly as filler material, in the case where long-time is pressurized or fatigue load acts on,
Easily there is compression creep, stay the defects of depression, there are certain office to fall into for its fatigue resistance；Simultaneously as luffa belongs to
Natural plant fiber material, easily catches fire in the dry state, and there are larger hidden danger for its security against fire.
Zinc borate has good flame retardant effect, safe and non-toxic, cheap, performance is stablized as a kind of fire retardant；Stone
The two-dimension periodic honeycomb lattice structure that black alkene is made of carbon hexatomic ring, is construct other dimension carbonaceous materials substantially single

In liquid, dipping modification is carried out to luffa as modifying agent, is distributed in making graphene uniform in luffa lumen, not only may be used
Greatly to lift the anti-fatigue performance of luffa, and the density and stability of luffa can be strengthened, while there is high return
Elasticity and anti-flammability.
Therefore, packing material of the high rebound flame retardant type luffa as sofa cushion is selected, passes through nontoxic polyethylene film
As adhesive, by techniques such as assembly in length and breadth, compound, the fabric claddings of lamination, making health is green, durable, and has
The sofa cushion of high resilience and anti-flammability.
The content of the invention
Proposed by the present invention is a kind of compound sofa cushion of luffa-polyethylene multilayer and preparation method thereof, its purpose is intended to
Make a kind of with good elastic sofa cushion.
The technical solution of the present invention：A kind of compound sofa cushion of luffa-polyethylene multilayer, its structure include sofa cushion
Filled layer；Sofa cushion filled layer includes L layers of longitudinal sheet luffa, N strata vinyl films, M layers of horizontal sheet luffa；Its
In, the upper surface of first layer longitudinal direction sheet luffa connects with the lower surface of first layer polyethylene film, and first layer polyethylene is thin
The upper surface of film connects with the lower surface of first layer transverse direction sheet luffa, the upper surface of first layer transverse direction sheet luffa and the
The lower surface of bilaminar polyethylene film connects, under the upper surface of second layer polyethylene film and second layer longitudinal direction sheet luffa
Surface connects, and so on；Wherein, L >=2, N >=2, M >=1；
The production method of the compound sofa cushion of luffa-polyethylene multilayer, comprises the following steps：
（1）It is prepared by water-based dipping modifying agent；
（2）It is prepared by sheet luffa；
（3）It is prepared by sheet luffa impreg；
