Problems solved by technology

[0004] Most of the pasted balls in the prior art are sizing after wrapping yarn outside the inner container, so as to realize the preparation of the rubber coating layer, and then sizing after wrapping the yarn. The yarn reduces the contact area between the slurry and the inner container of the sports ball, reducing the Guaranteed the patina effect on sports ball liner

preparation example Construction

[0033] 1. The preparation process of the modified natural latex is as follows: put 100ml of mixed solvent n-hexane / xylene (in volume ratio 1:1) in a 500ml four-necked flask, dissolve 50g of natural latex in it, and heat it at a temperature of 50°C. Heat to dissolve, and stir at a stirring speed of 100r / min, while feeding N 2 Bubble, reflux to dissolve in natural rubber latex, then add 24g of styrene / acrylonitrile mixture at 72°C, and add 2g of benzoyl peroxide at a weight ratio of 2:1, and carry out graft copolymerization at constant temperature reaction to obtain modified natural rubber latex.

[0034] Two, the preparation process of acrylic acid-silane film former is as follows:

[0035] (1) Ingredients: Weigh 40-50 parts of acrylic acid, 30-40 parts of acrylates, 20-30 parts of dimethylsilane, 5-10 parts of acrylamide, 5-10 parts of styrene, and 0.5-3 parts of initiator , 1-5 parts of emulsifier and 100-105 parts of water;

[0036] (2) Add water, emulsifier, acrylamide i...

Embodiment 1

[0039] A preparation process for tire yarn liner in a sports ball, comprising the steps of:

[0040] (1) Inflate the inner tube to the desired roundness;

[0041] (2) Immerse the yarn in water-based environmental glue;

[0042] (3) wrapping the impregnated yarn on the surface of the liner to obtain the yarn liner.

[0043] Among them, the water-based environmentally friendly glue is prepared by the following steps:

[0044] (1) Ingredients: 50 parts of modified natural rubber latex, 30 parts of hydroxyethyl methacrylate, 10 parts of silicone resin polyether emulsion, 5 parts of tea saponin, 1 part of sodium lauryl sulfate and 1 part of crosslinking agent DCP ;

[0045] (2) Add modified natural rubber latex and hydroxyethyl methacrylate to the reaction vessel for mixing and stirring, and the stirring time is 2 to 3 hours;

[0046] (3) Continue to add tea saponin, silicone resin polyether emulsion and sodium lauryl sulfate, and stir for 4 to 6 hours;

[0047] (4) Add a cros...

Embodiment 2

[0049] A preparation process of tire yarn liner in a sports ball, which is different from the first embodiment in that the formula of the water-based environment-friendly glue is different. Among them, 52 parts of modified natural rubber latex, 33 parts of hydroxyethyl methacrylate, 13 parts of silicone polyether emulsion, 7 parts of tea saponin, 2 parts of sodium lauryl sulfate and 1 part of crosslinking agent DCP are used for water-based environmental protection glue. share.

Abstract

The invention relates to a preparation technology of a tire yarn liner in a sport ball. The preparation technology comprises the following steps: (1) inflating an inner liner to the needed roundness;(2) immersing yarns into waterborne environment-friendly glue; (3) winding the immersed yarns on the surface of the inner liner to obtain the tire yarn liner; and immersing yarns in the waterborne environment-friendly glue and then covering the inner liner of the sport ball. According to the preparation technology, a traditional technology is replaced and a method for winding the yarns on the inner liner of the sport ball and then coating the glue is needed, the contact area between slurry and the inner liner of the sport ball is enlarged and the covering tightness of the yarns and the inner liner of the sport ball is enhanced; a subsequent preparation technology of the inner liner of the sport ball also can be simplified and the preparation cost is reduced; and the preparation technologyhas good environment-friendly performance.

Description

technical field [0001] The invention relates to the technical field of ball product processing, in particular to a preparation process of tire yarn bladders in sports balls. Background technique [0002] At present, the glue-bonded leather basketball (hereinafter referred to as the glued basketball) is composed of a four-layer structure of inner tube, skeleton layer, rubber covering layer and leather from the inside to the outside. The inner tube plays the role of storing gas and maintaining a certain airtightness; the surface of the inner tube is wrapped or wound with an appropriate amount of chemical fiber fabric or yarn to form a skeleton layer, and then the rubber is put into the mold to be vulcanized into a semi-finished product—the middle tire; the surface of the middle tire is sequentially treated Sanding, powder removal, solvent glue coating, and solvent glue coating on the back of the leather, and finally bonding each other to make the final product. [0003] Among...
