Embodiment 1

[0029] Embodiment 1 is based on superfiber synthetic leather skinned basketball and its preparation process, including:

[0030] 1. Preparation of microfiber synthetic leather

[0031] Add 60 parts of dibasic acid diamine polyurethane and 10 parts of nylon-66 salt into the stirring tank, raise the temperature to 150-180°C, stir for 10-15min; then add 30 parts of solvent, lower the temperature to 50-110°C, and remove the soaking to obtain a coating solution; adding the coating solution to a dipping machine, then putting microfibers into it for repeated dipping, and drying to obtain superfiber synthetic leather.

[0032] 2. Middle tire preparation

[0033] Add styrene-butadiene rubber, butadiene rubber, isoprene rubber and ethylene-propylene rubber to the internal mixer for mastication to obtain the initial rubber, then add fillers into the internal mixer to obtain the reinforcing rubber, and then put the foam The foaming agent is added to the mixing, and then extruded to obta...

Embodiment 2

[0037] Embodiment 2 is based on superfiber synthetic leather skinned basketball and its preparation process, including:

[0038] 1. Preparation of microfiber synthetic leather

[0039] Add 55 parts of dibasic acid diamine polyurethane and 145 parts of nylon-66 salt into the stirring tank, raise the temperature to 150-180°C, stir for 10-15min; then add 34 parts of solvent, lower the temperature to 50-110°C, and remove the soaking to obtain a coating solution; adding the coating solution to a dipping machine, then putting microfibers into it for repeated dipping, and drying to obtain superfiber synthetic leather.

[0040] 2. Middle tire preparation

[0041] Add styrene-butadiene rubber, butadiene rubber, isoprene rubber and ethylene-propylene rubber to the internal mixer for mastication to obtain the initial rubber, then add fillers into the internal mixer to obtain the reinforcing rubber, and then put the foam The foaming agent is added to the mixing, and then extruded to obt...

Embodiment 3

[0045] Embodiment 3 is based on superfiber synthetic leather skinned basketball and its preparation process, including:

[0046] 1. Preparation of microfiber synthetic leather

[0047] Add 50 parts of dibasic acid diamine polyurethane and 17.5 parts of nylon-66 salt into the stirring tank, raise the temperature to 150-180°C, stir for 10-15min; then add 37.5 parts of solvent, cool down to 50-110°C, and remove soaking to obtain a coating solution; adding the coating solution to a dipping machine, then putting microfibers into it for repeated dipping, and drying to obtain superfiber synthetic leather.

[0048] 2. Middle tire preparation

[0049] Add styrene-butadiene rubber, butadiene rubber, isoprene rubber and ethylene-propylene rubber to the internal mixer for mastication to obtain the initial rubber, then add fillers into the internal mixer to obtain the reinforcing rubber, and then put the foam The foaming agent is added to the mixing, and then extruded to obtain a high-el...

Abstract

The invention relates to the technical field of basketballs, in particular to a leather-pasted basketball based on microfiber synthetic leather and a preparation process of the leather-pasted basketball. The leather-adhered basketball comprises an outer skin, a middle tire and a leakage-proof hidden air tap, the outer skin is the microfiber synthetic leather, and the middle tire comprises a butyl liner, nylon threads and high-elasticity foamed rubber. According to the preparation process of the leather-pasted basketball, by using the microfiber synthetic leather as the outer skin, the prepared basketball has characteristics of good tear strength, high tensile strength, good air permeability, good folding resistance, good cold resistance, good mildew resistance, thick and full ball body, excellent grasping performance, increased ball contact feeling and increased skid resistance, and high-elasticity foaming rubber is added in the middle tire so as to provide the prepared basketball with characteristics of high elasticity, good mechanical strength, good flexibility, good shock resistance and good creep resistance.

Description

technical field [0001] The invention relates to the technical field of basketball, in particular to a superfiber synthetic leather-coated basketball and a preparation process thereof. Background technique [0002] Basketball is one of the favorite balls for young people. Basketball is divided into stitched balls and leather balls. The most common is leather basketball, which is made of inner liner, skin, ball mouth, etc. The inner liner is the bladder, which is the heart of the ball. , in the innermost layer of the ball, made of black rubber; the skin is divided into synthetic leather (superfine strong fiber, PU, ​​PVC, etc.) and genuine leather; the ball mouth is used to inflate the ball. The most used is polyurethane synthetic leather; [0003] The basketball prepared in the existing skin-coated basketball preparation process has poor tear resistance, low strength and insufficient elasticity. Therefore, a new skin-coated basketball preparation process is needed to improve...
