Abstract

The invention relates to a manufacturing method of a Marker ball, which belongs to a method for manufacturing the Marker ball by adopting silicone rubber. The manufacturing method mainly aims to solve the technical problems of hard texture, easiness in hurting a human body and high price of an existing Marker ball. The manufacturing method of the Marker ball adopts the technical scheme that the manufacturing method comprises the following steps of (1) preparing a silicone rubber ball: uniformly mixing and stirring a silicone rubber curing agent and silicone rubber according to the mass ratio of 1:20, then injecting mixed materials into a die, baking for 12h in an oven, and taking out the silicone rubber ball; (2) modifying the surface of the silicone rubber ball: preparing a polyvinylpyrrolidone (PVP) ethanol solution, preparing a silane coupling agent solution, modifying a coating, immersing the dry silicone rubber ball into the prepared polyvinylpyrrolidone (PVP) ethanol solution, then quickly taking out, and airing the surface of the silicone rubber ball at room temperature; (3) pasting a reflective film on the aired surface of the silicone rubber ball.

Description

technical field [0001] The invention relates to a method for making a Marker ball, which belongs to a method for making a Marker ball by using silicon rubber. Background technique [0002] At present, there are two main materials for marker balls: one is made of hard plastic, and the other is made of cotton; in laboratories in our country, hard plastic is generally used. It is hard and easy to cause harm to the human body; while it is made of cotton material abroad, but it is expensive. Contents of the invention [0003] The purpose of the present invention is to solve the technical difficulties of the existing Marker balls that are hard, easy to cause harm to the human body, and expensive, and to provide a method for making Marker balls. Harm to the human body, low price and long service life. [0004] The technical scheme that the present invention adopts for solving the problems of the technologies described above is: [0005] A kind of manufacture method of Marker b...
