The invention is described in further detail below with reference to the accompanying drawings and specific embodiments.
Fig. 1 is a schematic view of a dart board and its structure.
Fig. 2 is a schematic structural diagram of a dart board base 1 according to the present invention.
In the figure: a base 1; 1-1 of a groove; a metal sheet 2; a marking sheet 3.
Detailed Description
The present invention relates to the field of toys, and more particularly to a dart board and a manufacturing method thereof, which are described below with reference to fig. 1 and 2, and the dart board comprises a base 1, a metal sheet 2 and a marking sheet 3, and can be used for concentrating two types of dart boards on one board and simultaneously enabling one dart board to meet two use requirements.
In the present invention, for a clearer description, the following explanation is made: when an observer views the attached drawings 1, the left side of the observer is set as the rear, the right side of the observer is set as the front, the front side of the observer is set as the left, the rear side of the observer is set as the right, the upper side of the observer is set as the upper, and the lower side of the observer is set as the lower, it should be noted that the terms "upper end", "inner", "upper", "lower", and the like in the text indicate the orientation or positional relationship set on the basis of the attached drawings, and are only for the convenience of clearly describing the present invention, but do not indicate or imply that the structure or parts indicated must have a specific orientation, be configured in a specific orientation, and thus cannot be understood as limiting the present invention. Furthermore, the terms "first," "second," and the like are used for purposes of clarity and simplicity of description only and are not to be construed as indicating or implying a relative importance or quantity.
As a preferred embodiment of this embodiment, the base 1 is provided with a groove 1-1; the metal sheet 2 and the marking sheet 3 are arranged in the groove 1-1, and the base 1 is made of foam.
The method comprises the steps of adding a recycled foam material which is crushed into fine particles or powder and polyester fibers into a raw material made of foam on a base 1, uniformly blending the recycled foam material and the raw material by stirring, and pouring the mixture into a mold to form new foam integrally by foaming, wherein the recycled foam material accounts for 2.5-20 wt%, and the polyester fibers account for 5 wt%.
The raw materials for preparing the foam comprise PPG polyether glycol, MC methylene dichloride, stannous zincate, silicone oil, an amine catalyst, water and TDI toluene diisocyanate, and the preparation method comprises the steps of mixing and modulating the raw materials, adding a foam reclaimed material and polyester fibers which are crushed into fine particles or powder, uniformly blending the foam reclaimed material and the raw materials through stirring, and foaming and forming the foam reclaimed material and the raw materials together.
Specifically, the raw materials for making the foam are also added with a fire retardant to improve the fire resistance of the foam.
The metal sheet 2 is made of an iron sheet, the metal sheet 2 and the mark sheet 3 are placed at one end of the groove 1-1 of the base 1 so as to use the magnet dart, the base 1 is made of a foam material, and the back of the base 1 is convenient for the insertion type dart to use.
The foam recovery material used in the invention can be selected from foam residue or waste materials, and is crushed into fine particles or powder by a machine, the particle size of the crushed foam recovery material is controlled within the range of 0.05 mm-1.7 mm, for example, the recovered foam is crushed into particles with the sizes of 0.05mm, 0.08mm, 0.10mm, 0.15mm, 0.2mm, 0.5mm, 0.8mm, 1.00mm, 1.2mm, 1.5mm and the like. The weight ratio of the recycled foam material is 2.5-20%, more than 20% of the recycled foam material affects the quality and color of the product, and less than 2.5% of the recycled foam material does not achieve the effect of environmental protection recycling, and experimental inspection shows that the recycled foam material accounts for 3-15% of the recycled foam material is preferable, and the specific situation depends on the actual situation. The adding proportion of the foam recycled material is inversely proportional to the particle size, namely, the smaller the powder particles, the more the foam recycled material can be added, in the manufacturing process, 3%, 5%, 8%, 10%, 12%, 15% or 18% of the foam recycled material can be properly selected and added, the proportion control mainly ensures that the foam recycled material can be fully fused with other mixed raw materials when being mixed and stirred, and further the foam recycled material can be uniformly synthesized in a formed foam structure during foam forming, so that the new environment-friendly foam which has good color, elasticity and structural strength and is almost equal to brand-new foam formed foam is obtained. For example, the recycled foam material is crushed into 0.10mm powder, 15% of the recycled foam material is added into the foam raw material, and the produced foam finished product is almost the same as the foam finished product produced by a pure new raw material because the recycled foam material is sufficiently fine and has proper addition amount, can be completely blended with other mixed raw materials, and does not affect the product quality. For another example, the recycled foam material is crushed into 1.00mm fine particles, and the addition amount is properly reduced due to the larger particles, for example, the addition amount is 5%, so that the recycled foam material can be fully fused into other mixed raw materials, and foaming molding is not influenced.
It is to be understood that the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and that various changes, modifications, additions and substitutions which are within the spirit and scope of the present invention and which may be made by those skilled in the art are also within the scope of the present invention.
