Embodiment 1

[0033] The liner of the present invention contains polyvinyl chloride paste resin: 50%, plasticizer 45%, and barium-zinc stabilizer 5%.

Embodiment 2

[0035] The liner of the present invention contains polyvinyl chloride paste resin: 50%, plasticizer 47%, and barium-zinc stabilizer 3%.

[0036] In reality: since the inner tank of the present invention mainly uses polyvinyl chloride material, and the use of rubber material is omitted, the airtightness and elasticity of the inner tank are effectively improved.

[0037] In addition, the present invention also provides a method for making an inner container for sewing sports balls, which includes the following steps in sequence:

[0038] Step 1: Mix the raw materials according to the formula, and stir evenly in a high-speed mixing tank;

[0039] Step 2: Use a vacuum defoamer to completely remove the air bubbles inside the mixture;

[0040] Step 3: inject the defoamed mixture into a spherical mold through a feeder, and then heat, roll and solidify in a rotary kiln at a temperature of 200-300°C for 3-10 minutes;

[0041] Step 4: After the spherical mold is out of the furnace, co...

Embodiment 3

[0043] A method for making an inner liner for sewing sports balls, comprising the following steps in sequence:

[0044] Step 1: Mix the raw materials according to the formula, and stir evenly in a high-speed mixing tank;

[0045] Step 2: Use a vacuum degassing machine to completely remove the air bubbles inside the mixture, and then match the color;

[0046] Step 3: inject the defoamed mixture into a spherical mold through a feeder, and then heat, roll and solidify for 6 minutes in a rotary kiln at a temperature of 250°C;

[0047] Step 4: After the spherical mold is out of the oven, cool it in warm water to below 100°C, then release the inner bladder, and press the valve core within 1 minute, then inflate and shape the mold in the standard bladder mold, and then cool naturally to room temperature.

[0048] The equipment used in this process is as follows: 1 batching mixer, power: 15KW; 1 color matching table, power: 5KW; 1 rotational molding rotary furnace, power: 7KW; 1 air ...

Abstract

The invention discloses a sewed type sport ball which is characterized in that an inner container which is made from polyvinyl chloride is adopted. The invention further discloses a manufacturing method of the inner container of the sewed type sport ball. The method includes in sequence the following steps: step1: mixing raw materials according to a formula and evenly stirring the raw materials in a high-speed stirring bucket; step 2: thoroughly removing bubbles inside the mixed materials through a vacuum defoaming machine; step 3: injecting the defoamed mixed materials into a ball-shaped die through a charging machine, then, conducting heating rolling solidification forming for 3 minutes to 10 minutes in a rotary furnace with a temperature of 200 DEG C to 300 DEG C; and step 4: drawing the inner container out of the die after the die is drawn out of the furnace and is cooled in warm water the temperature is below 100 DEG C, pressing the inner container into a valve core within one minute, then, naturally cooling the inner valve core to a normal temperature after aeration forming is conducted in a standard bladder die. The sewed type sport ball is not only good in air impermeability and bounce capability, but also low in recycle cost, causes no secondary pollution to the environment and is simple in manufacturing process and low in energy consumption.

Description

technical field [0001] The invention relates to a sports ball, in particular to a sewing sports ball, and also relates to a method for making an inner tank of the sewing sports ball. Background technique [0002] At present, the inner bladders of various sewing sports balls are mainly used to store air and maintain pressure, thereby improving the bouncing performance of the balls. So far, the liners of various sewing sports balls in the world are usually made of 40%-50% natural rubber, about 10% synthetic rubber, 30-40% carbon powder, calcium carbonate powder and accelerators. , this kind of ball liner mainly made of rubber materials, due to the natural characteristics of rubber materials, a large amount of carbon powder and calcium carbonate powder must be added for rolling, resulting in poor air tightness and elasticity. During the production, several rubber mixers are required to carry out three to four stages of rolling and filtering, and finally high-temperature vulc...
