Problems solved by technology

But when pouring the white part, because the colored part has been cured and loses its activity, if the white part is directly cured on the surface of the colored part, the connection strength between the two is not good, which causes the product to produce balls during use defect of mistake

Embodiment Construction

[0015] In order to better understand the technical solution of the present invention, the following will be described in detail through specific examples:

[0016] The bonding method of the colored part and the white part of the phenolic resin billiard ball of the present invention comprises the following steps:

[0017] Step 1: Pour colored raw materials into the first mold to form the colored part of the billiard ball; spray a release agent (Hiri741 silicon type) in the first mold before pouring;

[0018] Step 2: Curing the colored part of the billiard ball first, the curing temperature is 70-90°C, the curing time is 1.5-2.5 hours, and then demoulding;

[0019] Step 3, increase the roughness of the surface of the colored part of the billiard ball; use sandpaper to polish the surface of the colored part of the billiard ball, so that the release agent on the surface of the colored part can be removed, and the roughness of the surface of the colored part can be increased;

Abstract

The invention discloses a method for bonding a colored part and a white part of a phenolic resin billiard. The method comprises the following steps of: firstly, casting a colored material in a first die, so as to form the colored part of the billiard, secondly, performing curing process on the colored part of the billiard, with the curing temperature being 70 to 90 DEG C and the curing temperature being 1.5 to 2.5 hours, and then performing demolding, thirdly, increasing the surface roughness of the colored part of the billiard, fourthly, cleaning the surface of the colored part of the billiard, fifthly, putting the colored part of the billiard into a second die, and casting white material in the second die, so as to form the base body of the billiard, and sixthly, performing curing process on the base body of the billiard, with the curing temperature being 70 to 90 DEG C and the curing temperature being 3.5 to 4.5 hours, and then performing demolding, so as to obtain the billiard. The method can effectively bond the colored part and the white part of the billiard body to form a whole body, and can also ensure that a boundary line between the colored part and the white part of the billiard body is obvious.

Description

technical field [0001] The invention relates to a bonding method for a colored part and a white part of a phenolic resin billiard ball. Background technique [0002] In Billiards each ball is composed of white and colored (except numbers). When making these billiard balls, the colored part is usually made first, and after curing, the white part is poured on it. But when pouring the white part, because the colored part has been cured and loses its activity, if the white part is directly cured on the surface of the colored part, the connection strength between the two is not good, which causes the product to produce balls during use Flaws of mistakes. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a method for bonding the colored part and the white part of a phenolic resin billiard ball, which can effectively bond the colored part and the white part of the sphere into one body and ensure ...
