Description

Laminated table tennis rackets

The present invention relates to a sports equipment and, more particularly, to a laminated table tennis racket.

Table tennis is a popular ball game in China and is very popular in China. There are table tennis courts and table tennis fans everywhere. Formal table tennis players all wear rubber before the start of the game to ensure a good batting return effect. However, amateur table tennis players and table tennis fans can not satisfy this requirement and usually use the same racket. The effectiveness of a table tennis racket is especially important in ensuring the effectiveness of use.

Therefore, studying and producing a table tennis racket capable of ensuring a long-term hit effect is a serious problem that ordinary intellectuals in the technical field of the present invention should urgently solve.

In order to solve the above-mentioned problems, the present invention discloses a laminated table tennis racket.

In order to achieve the above-mentioned object,

A plate, a filler material filling layer and a rubber layer; A material filling hole is uniformly penetrated through the surface of the plate;

The batting surface material filling layer includes a racquet side adhesive layer and a flexible intermediate layer;

The racquet side adhesive layer comprises a fibrous layer and an adhesive foam; The fibrous layer is adhered to both the top and bottom sides of the plate via an adhesive foam; The flexible intermediate layer is provided with the deforming protrusions uniformly on one side and the pimples on the other side equally; The pimples are matched with the material filling holes and are provided therein;

The rubber layer is provided on one side of the plate remote from the flexible intermediate layer. The composition component and the mass percentage of each component are 16-23 parts by weight of butadiene rubber, 10-17 parts by weight of ethylene propylene rubber, 2-5 parts by weight of softener, 3 to 5 parts by weight of a plasticizer, 1 to 3 parts by weight of a stabilizer, and 5 to 8 parts by weight of a calcium powder.

The table tennis racket provided by the present invention is constituted by a plate, a filling layer of a ball surface material and a rubber layer, and the material filling hole is uniformly penetrated and formed on the surface of the plate so as to match the filling layer of the ball surface material. In the present invention, the filling layer of the hitting face material is composed of a racquet side adhesive layer and a flexible intermediate layer. Among them, the rake face adhesive layer is composed of a fiber layer and an adhesive foam, and the fiber layer is adhered to the upper and lower sides of the plate through the adhesive foam to adhere the fiber layers to both sides of the plate, and to provide a certain deformation space and elasticity to the fiber layer. The flexible intermediate layer has the deforming protrusions uniformly on one side and the pimples on the other side equally, and the pimples are matched to the material filling holes. The deforming projection supports the outermost rubber layer and the pimple supports the flexible intermediate layer.

In the present invention, the rubber layer is composed of butadiene rubber, ethylene propylene rubber, softener, plasticizer, stabilizer and calcium powder. The butadiene rubber is superior in cold resistance and abrasion resistance and particularly in elasticity to rubber materials of the prior art, but also has a disadvantage in that the anti-aging performance is deteriorated. The addition of ethylene propylene rubber improves the resistance to aging such as ozone resistance, heat resistance and weatherability as a whole, which can compensate for the lack of aging resistance of the butadiene rubber. By adding softening agent, it improves the processing performance and the use performance as a whole and improves the overall flexibility, so that it is convenient for users to join themselves. At the same time, when the plasticizer is matched, the abrasion resistance can be improved as a whole. When calcium powder is used as a filler, the overall volume of the rubber is increased to reduce the amount of ethylene propylene rubber used in the butadiene rubber home, lower the production cost, and obtain better overall tensile strength, tear strength and abrasion resistance. Addition of a stabilizer can improve the stability of each component when it is fused. In the present invention, the rubber has excellent weatherability and anti-aging performance, while ensuring that the present invention has excellent elasticity.

Preferably, the more the adhesive foam forms a spherical structure and the adhesive form near the material filling hole, the greater its elastic modulus becomes.

In the present invention, the adhesive foam has a spherical structure. The present invention is designed such that the elastic modulus increases gradually as the adhesive form is closer to the material filling hole, so that the adhesive foam around the material filling hole is more easily deformed by the impact of the table tennis, thereby assuring return elasticity and stability.

Preferably, the pimple has a columnar structure, a spiral pattern is uniformly provided on its surface, and a spiral pattern of two pimples in the same material filling hole is opposite to the pattern direction.

In the present invention, the pimples have a columnar structure, and the surface of the pimples is uniformly provided with a spiral pattern so as to ensure stable matching of the pimples and the material filling holes, and also to ensure that there is a certain gap between the pimples and the material filling holes, By effectively distributing it, it is possible to remove moisture and moisture penetrating into it and to ensure dryness inside the table tennis racket, thus guaranteeing the hit, return effect and service life of the table tennis racket.

Preferably, the fibrous layer includes a stomach fiber layer, a resilient layer and a lower fiber layer as a laminated structure; The upper fibrous layer and the lower fibrous layer intersect each other; The elastic layer is provided between the upper fibrous layer and the lower fibrous layer.

In the present invention, the fibrous layer is designed in a laminated structure, and is composed of a stomach fiber layer, a resilient layer and a lower fiber layer, wherein the stomach fiber layer and the lower fiber layer intersect each other to include a resilient layer therein, The laminated structure surface including the recessed grooves is formed and the elasticity of the entire fiber layer is ensured through the upper elastic fiber layer, the lower elastic layer and the lower elastic layer.

Preferably, the compositional components of the upper fibrous layer and lower fibrous layer and the mass percentage of each component are 15-23 parts by weight of spandex, 7-11 parts by weight of fluorine rubber, 2-5 parts by weight of zinc stearate, and 1-3 parts by weight of a viscosity reinforcing agent .

In the present invention, the upper fibrous layer and the lower fibrous layer are composed of spandex, fluororubber, zinc stearate and a viscosity reinforcing agent having the same compositional components. Spandex is more resilient, more dense in density, more cross-reactive, more resistant to chemical degradation and more environmentally friendly. Spandex is excellent in acid resistance / alkalinity, sweat resistance and abrasion resistance so that the upper and lower fiber layers can be used for a longer time. The fluorine rubber has excellent elasticity, and is excellent in heat resistance, antioxidation and corrosion resistance. Zinc stearate can achieve stability, lubricity, and viscosity-enhancing effect. The viscosity reinforcing agent can increase the adhesion and bond strength between spandex and fluorine rubber.

Preferably, the elastic layer is woven with linear polyethylene as a stick-like elastic filling material.

In the present invention, the elastic layer is made of a stick-like elastic filling material woven with linear polyethylene, so that the elastic layer has better low temperature resistance and can resist most erosion of acidity and alkalinity. It is also possible to ensure that the elastic layer is woven with linear polyethylene to have similar performance to polyethylene, as well as the overall stability of the elastic layer.

Preferably, the material filling hole has an hourglass shape in the longitudinal section.

In the present invention, the material filling hole designes the longitudinal section in an hourglass shape. Among them, the pimples are designed to match each other based on the shape of the material filling hole, ensuring that the pimples are matched with the material filling holes, while ensuring that the pimples are able to support the flexible intermediate layer.

Preferably, the center of the pimples is further provided with a through hole along the axial direction.

In the present invention, the center of the pimple is provided with a through hole along the axial direction so that not only the elasticity of the pimple can be improved to some extent, but also the service life can be extended to some extent.

Preferably, the deforming projection constitutes the longitudinal section in the form of a semi-circular or semi-circular shape.

In the present invention, the deforming protrusions are uniformly designed. The longitudinal protrusions are formed in a hot or semicircular shape, so that the two adjacent deforming protrusions provide a constant elasticity to leave a certain space for deformation of the rubber layer and further improve the hit and return quality.

The present invention has a longer life and a better ball return effect because it has better weather resistance, anti-aging performance and rubbery elasticity than the conventional table tennis racket.
