Abstract
The invention relates to an EVA cushion core material for a sofa cushion. The formula involves polyethylene vinyl acetate. The preparation method comprises the steps of: 1. subjecting polyethylene vinyl acetate granules to heating extrusion by a twin-screw extruder to form a colloidal state; 2. letting the colloidal state polyethylene vinyl acetate enter a die to form strips; 3. pouring the strip polyethylene vinyl acetate into a water pool to perform water cooling; 4. carrying out air drying by a machine; and 5. conducting edge cutting to form a required shape. The heating temperature of the twin-screw extruder is 230-240DEG C, the diameter of the strip polyethylene vinyl acetate is 0.5-1.5mm, and preferably the diameter of the strip polyethylene vinyl acetate is 1mm. The EVA cushion core material for the sofa cushion provided by the invention has the advantages of good cushioning performance, shock resistance, heat insulation, moisture proofness, and chemical corrosion resistance, etc., and is non-toxic, does not absorb water, omits the spring, and effectively extends the service life of the sofa cushion. Also, the sofa cushion is easy to prepare, and the production cost is reduced.
Description
Technical field
The invention belongs to technical field of furniture, specifically, relate to EVA cushion core material of good, the on-deformable sofa cushion of a kind of resiliency and preparation method thereof.
Background technology
Along with socioeconomic development, the raising of people's living standard, the furniture such as sofa have entered in ordinary people family.
In order to cushion the impulsive force produced when user sits or lies in sofa and seat, increase the comfort of furniture, when manufacturing furniture, usually cushion is filled at the seat surface of furniture or back part, to play the effect of preliminary buffering, sofa cushion has been indispensable furniture accessories in present society, and in the prior art, people usually in the framework of furniture mounting spring or elastic band to play the effect of buffering further.
But, spring material has the following disadvantages, more complicated professional technique is needed when installing and implementing, if use for a long time, the junction of spring and framework can produce noise, and owing to being electrical equipment everywhere in present our family, the spring of metal material can with electrostatic, and electrostatic is harmful to the health of people.
And more existing sofa cushion adopts sponge, but sponge sucks in water, and moisture resistance is poor, especially in the Guangdong of sweltering heat, is easy to mouldy, and this just shortens the service life of sofa cushion.
Summary of the invention
Instant invention overcomes shortcoming of the prior art, EVA cushion core material providing a kind of sofa cushion and preparation method thereof, it has the advantages such as good buffering, antidetonation, heat insulation, moistureproof, resist chemical, extends the service life of sofa cushion, prevents the generation of electrostatic.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions:
An EVA cushion core material for sofa cushion, its formula is plastic of poly vinyl acetate.
A preparation method for the EVA cushion core material of sofa cushion, its step comprises:
1) plastic of poly vinyl acetate grain is undertaken adding hot-extrudable by double screw extruder, forms colloidal state;
2) plastic of poly vinyl acetate of colloidal state enters mould and forms strip;
3) strip plastic of poly vinyl acetate is poured pond into and is carried out water-cooled;
4) machine is air-dry;
5) trimming forms the shape needed.
Further, the heating-up temperature of described double screw extruder is 230-240 DEG C.
Further, the heating-up temperature of described double screw extruder is 235 DEG C.
Further, the plastic of poly vinyl acetate diameter of described strip is 0.5-1.5mm.
Further, the plastic of poly vinyl acetate diameter of described strip is 1mm.
Compared with prior art, the invention has the beneficial effects as follows:
The EVA cushion core material of a kind of sofa cushion of the present invention, there is the advantages such as good buffering, antidetonation, heat insulation, moistureproof, resist chemical, and without glue, not containing formaldehyde, nontoxic, do not absorb water, eliminate spring, effectively extend the service life of sofa cushion, and sofa cushion manufacture is simple, reduces production cost.
Detailed description of the invention
The EVA cushion core material of a kind of sofa cushion of the present invention, its formula is plastic of poly vinyl acetate, adopts plastic of poly vinyl acetate particle, and production technology is simple, and do not need to add other any auxiliary agents, production cost is low.
A preparation method for the EVA cushion core material of sofa cushion, its step comprises:
1, first plastic of poly vinyl acetate grain is poured in double screw extruder, by double screw extruder, plastic of poly vinyl acetate grain is heated, the heating-up temperature of double screw extruder is 235 DEG C, then extrude, plastic of poly vinyl acetate particle shape becomes colloidal state, the heating-up temperature of 235 DEG C can obtain best plastic of poly vinyl acetate colloid, and the sofa cushion cushion core material obtaining optimum performance for subsequent step is ready;
2, the plastic of poly vinyl acetate of colloidal state forms the plastic of poly vinyl acetate of strip by mould, the plastic of poly vinyl acetate diameter of strip is 1mm, through inventor's many experiments, sofa cushion cushion core material shock-absorbing capacity, the anti-seismic performance of the plastic of poly vinyl acetate formation of the strip of 1mm are best;
3, the plastic of poly vinyl acetate of strip is poured pond into and is carried out water-cooled, and the plastic of poly vinyl acetate of strip is bending, inter-adhesive in pond, forms nest like;
4, nest like plastic of poly vinyl acetate is air-dry by machine, is removed by water;
5, by bead cutter, the nest like plastic of poly vinyl acetate of bulk is cut into the shape of needs.
Last it is noted that these are only the preferred embodiments of the present invention; be not limited to the present invention; although with reference to embodiment to invention has been detailed description; for a person skilled in the art; it still can be modified to the technical scheme described in foregoing embodiments; or equivalent replacement is carried out to wherein portion of techniques feature; but it is within the spirit and principles in the present invention all; any amendment of doing, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
