Abstract
The invention discloses an ethylene vinyl acetate (EVA) adhesive tape, and relates to an adhesive tape coated with an adhesion layer. The EVA adhesive tape comprises a base layer and an adhesion layer. The adhesion layer is coated on the base layer. The base layer comprises EVA, a mixture of EVA and polypropylene (PP), or a mixture of EVA and polyethylene (PE). A preparation method of the EVA adhesive tape comprises the following steps of 1, processing base materials into a sheet, 2, carrying out electrophoresis treatment on the sheet, 3, adjusting viscosity of a polymethyl methacrylate-containing adhesion layer, 4, coating the polymethyl methacrylate-containing adhesion layer treated by the step 3 on the sheet subjected to the electrophoresis treatment to obtain a sheet with an adhesion layer, 5, carrying out heating setting of the adhesion layer obtained by the step 4, and 6, cutting the sheet with the adhesion layer into slices, and sheeting and packaging the slices. The EVA adhesive tape is environmentally friendly and pliable, has good elasticity, and can be widely utilized for wrapping tapes of handles of exercisers such as tennis rackets, badminton rackets and the like, dresses and personal adornments, shoes, toys, interior decorations, vehicle trims, wires and cables.
Description
Technical field
The present invention relates to be covered with the adhesive tape of adhesive-layer; Especially a kind of EVA adhesive tape; Be widely used in the handle of be wrapped sports movement apparatus such as tennis racket, racket, golf club etc. and the handle of the relevant articles for daily use that are wrapped, also be applicable to toy, dress ornament, decoration and electric wire etc.
Background technology
The general looping adhesive tape of handbar (claiming the handle skin again) of sports movement apparatus such as one of which, tennis racket, racket, golf club to increase elasticity, is convenient to change, and keeps clean.In the prior art, the handle skin is mainly made by PU (Polyurethane, down together) or PVC (SE, down together), and the especially final part that finishes up is used the PVC electrical adhesive tape all the time.PVC is not had a feature of environmental protection, and it contains phthalic acid, can produce Dioxins during burning, and contaminate environment is harmful, has American-Europeanly begun to forbid the product that contacts with the human body easily use PVC made like sports movement apparatus.
Its two, dress ornament class and footwear also are the products that contacts with human body easily, also use adhesive tape or film on it.In the prior art, its adhesive tape or film are generally made with PVC, and be harmful, contaminate environment.
Its three, the toys product also is the product that contact with human body easily, even contacts with baby, children's hand or mouth easily, adhesive tape of use or film generally also with the PVC making, injure bigger to baby, child's torso on it.
Its four, aspects such as interior decoration, automobile interior and electric wire, the adhesive tape of use or film are generally also made with PVC, do not meet environmental requirement.
A kind of environmental protection of market demand, production cost hang down and adhesive tape easy to use.
Summary of the invention
The present invention is intended to overcome the above-mentioned deficiency of prior art and satisfy market demand, releases a kind of EVA adhesive tape, has environmental protection, low, the easy to use and broad-spectrum characteristics of production cost.
To achieve these goals, accomplish above-mentioned task, a kind of EVA adhesive tape of the present invention adopts following technical scheme.
A kind of EVA adhesive tape is made up of basic unit and adhesive-layer, and adhesive-layer is overlying in the basic unit;
The composition of basic unit is EVA, and its EVA is the multipolymer of ethene and vinyl acetate between to for plastic; Perhaps be EVA and PP, its PP is a polyethylene terephthalate; Perhaps be EVA and PE, its PE is a Vilaterm;
The composition of adhesive-layer is polymethyl methacrylate, i.e. polymethyl methacrylate.
The method of making is:
1., EVA particulate basic unit material or EVA and PP particulate basic unit material or EVA and PE particulate basic unit material are shaped be lamellar body;
2., more said lamellar body is carried out corona treatment;
3., the viscose glue layered material that contains polymethyl methacrylate is carried out the viscosity allotment;
4., the viscose glue layered material that contains polymethyl methacrylate that will allocate viscosity again is coated in through on the said lamellar body of corona treatment and forms adhesive-layer;
5., again to the setting of heating by the adhesive-layer that 4. forms;
6., again to cut into the sheet of different size specification through the said lamellar body itemize after 5. handling, sheet is carried out on chip or package.So-called finger on chip adopts the sheet method to the sheet of certain size specification, and its finished product is a sheet; So-called package refers to the sheet of some dimensions adopted the web-like method, the finished product of the volume that rolls up.
A kind of EVA adhesive tape of the present invention, its beneficial effect is:
One of which, environment-friendly type.EVA or PEVA (PEVA adds PP or PE among the EVA) are biodegradable, discard or can not pollute environment when burning; Have no stink, do not contain heavy metal, do not contain phthalate, can not produce the danger that softening agent disengages.Polymethyl methacrylate also has the same feature of environmental protection.
Its two, pliable and tough, be rich in good elasticity.As long as mainly that the content allotment of ethene and vinyl acetate between to for plastic is suitable, just can obtain needed pliable and tough and elasticity.
Its three, the major ingredient of adhesive-layer is a polymethyl methacrylate, its viscosity is good, stickiness is good, it is convenient to paste, heat-resisting cold-resistant.Simultaneously, because corona treatment is carried out on the surface of basic unit, improved the bonding firmness of adhesive-layer and basic unit.
Its four, can implement color printing easily at the back side of EVA or PEVA basic unit, like color printing name of product, manufacturer and brand mark etc., be difficult for decolouring, convenient, economic and durable.
Its five, purposes is wide, can be widely used in: the looping adhesive tape of the handbar of sports movement apparatus such as tennis racket, racket and golf club; Dress ornament class and footwear; The toys product; Interior decoration, automobile interior and electric wire etc.
Description of drawings
Fig. 1 is a diagrammatic cross-section of the present invention;
Fig. 2 is a synoptic diagram of the present invention on chip;
Fig. 3 is the synoptic diagram of the present invention of package.
Among the figure: 1, basic unit; 2, adhesive-layer.
Embodiment
Below, in conjunction with accompanying drawing, introduce embodiment of the present invention.
As shown in Figure 1, a kind of EVA adhesive tape is made up of basic unit and adhesive-layer, and adhesive-layer is overlying in the basic unit;
The composition of basic unit 1 is EVA, and its EVA is the multipolymer of ethene and vinyl acetate between to for plastic; Perhaps be EVA and PP, its PP is a polyethylene terephthalate; Perhaps be EVA and PE, its PE is a Vilaterm;
Adhesive-layer 2 is polymethyl methacrylate, i.e. polymethyl methacrylate.
The method of making is:
1., will contain EVA particulate basic unit expects, perhaps contains EVA and PP particulate basic unit material, perhaps contains EVA and PE particulate basic unit material through being mechanically formed into lamellar body; Or even the lamellar body of film like; That is to say that the thickness of said lamellar body is adjustable, look concrete purposes and decide; Its machinery can be general plastic molding machinery, also can be special-purpose forming machine.
2., more said lamellar body is carried out corona treatment; This step is mainly following step and 4. prepares, and through corona treatment, makes the surface of said lamellar body become more coarse, causes adhesive-layer to combine more firmly with basic unit.
