Problems solved by technology

[0002] Ocean balls are products for infant playgrounds, baby tents, naughty castles and outdoor activities, etc. Generally, ocean balls are made of plastic, and their thickness is generally less than 0.25mm, and their compressive strength is relatively small. Running out of air loses its elasticity, and there is also the possibility of bursting during infants' play
Moreover, the ocean balls that are blown from ordinary plastics are relatively rough at the mold seams and feel bad when used.
At present, most of the ocean balls on the market are simple single-color spheres. Infants and young children are relatively single in the process of playing, and it is not easy to grasp, and it is easy for infants and young children to lose interest in ocean balls.
[0003] The patent application No. 201220753507.0 discloses a safe and long-life inflatable marine ball, but this marine ball is prone to air leakage if it receives external force during use or after a long time of use

Embodiment 1

[0022] Formed by conventional polystyrene foam molding methods such as figure 1 For the ball core with a diameter of 4 cm, open the designed mold with an inner diameter of 6 cm. There is a thimble at the center of both sides of the mold, which can fix the polystyrene foam core at the center of the mold. Enter thermoplastic polyurethane micro-foaming material particles, until it is full, feed 1.5MPa high-temperature steam, keep warm for 6 minutes, feed cooling water to cool, open the mold, take out the sphere to get a polystyrene foam core with a diameter of 4 cm and a 1 cm thermoplastic polyurethane micro-foam core. Elastic balls of foam molding layer.

Embodiment 2

[0024] Formed by conventional polystyrene foam molding methods such as figure 2 For the core shown in the figure, open the designed mold with an inner diameter greater than 1cm of the core, fix the polystyrene foam core in the center of the mold, close the mold, and fill the thermoplastic polyurethane micro-foaming material particles from the mold material hole until it is full. Introduce high-temperature steam of 3 MPa, keep warm for 8 minutes, infuse cooling water for cooling, open the mold, and take out the sphere to obtain such figure 2 The shown polystyrene foam core is an elastic ball with a molding layer of 1 cm thermoplastic polyurethane micro-foam material. The use of unconventional balls can be convenient for infants and young children to grasp, and the interest of infants and young children in ocean balls can be improved.

[0025] Different from the above-mentioned embodiments, the diameter of the ball core is in the range of 1-10 cm.

[0026] Different from the...

Abstract

The invention relates to an elastic ball, in particular to a preparation method of an ocean ball. The elastic ball of the invention uses the PBAT thermoplastic biodegradable plastic as a ball core andthe outer layer is coated with the thermoplastic polyurethane micro-foaming material, which has better impact resistance, reduces the weight and prevents the occurrence of air leakage phenomenon; meanwhile, the preparation method is simple, the production process is free from any environmental pollution and the product is harmless.

Description

technical field [0001] The invention relates to an elastic ball, in particular to a marine ball, and in particular to a method for preparing an environment-friendly marine ball. Background technique [0002] Ocean balls are products for infant playgrounds, baby tents, naughty castles and outdoor activities, etc. Generally, ocean balls are made of plastic, and their thickness is generally less than 0.25mm, and their compressive strength is relatively small. Running out of gas loses its elasticity, and at the same time it may explode during infants' play. Moreover, the marine balls that adopt ordinary plastic blow molding are relatively rough at the mold seams, and feel bad when used. Most of the marine balls on the market are simple single-color spheres. Infants and young children are relatively single in the process of playing, and they are not easy to grasp, which easily makes infants lose interest in marine balls. [0003] The patent application No. 201220753507.0 disclo...
