A kind of preparation method of badminton head

Abstract

The invention discloses a preparation method of a badminton head, and relates to the field of badminton. The preparation method of the badminton head comprises the steps that (1) a badminton head moldis preheated with heating temperature of 200-250 DEG C and heat preservation for 10-15min; and then the heating temperature is cooled to 120-160 DEG C, heat preservation is carried out for 15-20 min,and the temperature of the arc part at the bottom of a mold is reduced by 10 DEG C by using cold water below 5 DEG C; (2) the arc part at the bottom of the badminton head mold is coated with a layerof m-xylene, badminton head raw materials are injected into the badminton head mold, the badminton head raw materials are compressed with a compaction block, and heat preservation is carried out for 3-3.5h to obtain a semi-finished badminton head product; (3) the temperature of the mold with the semi-finished badminton head product is increased to 220-260 DEG C, heat preservation is carried out for 8-10 min, the mold is quickly cooled to room temperature with standing of 2-3 min, the semi-finished badminton head product is taken out; (4) the end surface of the semi-finished badminton head product is cut flat, polished and evenly perforated, and the periphery of the top end of a hole is coated with a layer of adhesive, thickness of the adhesive is 0.2-0.3 mm, and the badminton head is obtained. By adopting a mold forming method, the material of the prepared badminton head has uniform components, good integrity and is not prone to being damaged.

Description

Technical field: [0001] The invention relates to the field of badminton, in particular to a method for preparing a badminton head. Background technique: [0002] Badminton ball heads are mainly divided into four categories: foam ball heads, double ball heads, triple ball heads, and all-natural cork ball heads. The foam ball head is a white foam. The double ball head is the most common. It is usually a double fight small particle regenerated cork ball head. Cork, to achieve the strength of natural cork, the second half is table fiber, generally expressed as: "Small particles of regenerated cork double ball head, XXmm table fiber", XX represents the thickness of table fiber, there are double ball heads It is a pair of cork, the first half is natural cork, and the second half is table fiber, generally expressed as: "Natural cork double ball head, XXmm table fiber", XX represents the thickness of table fiber, and the triple ball head is generally natural cork + Taiwan fiber + ...

AI Technical Summary

Problems solved by technology

[0003] Therefore, at present, the materials of the front half and the back half of the badminton head are different, and glue must be used to fix the connection during processing. The problem caused by this is that the front half and the back half are easy to separate. The surface of the part and the second half is covered with a layer of sheepskin or other materials, which increases the production cost, and is prone to cracks at the hole of the ball head
