Embodiment 1

[0024] In the reactor, add 5 parts (parts by mass, the same below) of pentaerythritol, 15 parts of trimethylolpropane, 4 parts of propylene glycol, 4 parts of maleic anhydride, 14 parts of isononanoic acid, 21 parts of hexahydrophthalic anhydride, feed nitrogen and heat up to Stirring was started at 150°C, and then the temperature was raised to 230°C in steps of 10°C per hour. During the heating process, the gas phase temperature was controlled below 100°C, and the constant temperature was kept at 230°C until the sampling liquid level was transparent. After 30 minutes, slowly added 2 parts of xylene to control The reflux temperature is 225-230°C. After reflux for two hours, take a sample and test it. After passing the test, add 35 parts of xylene after cooling.

Embodiment 2

[0026] In the reactor, add 6 parts (parts by mass, the same below) of pentaerythritol, 14 parts of trimethylolpropane, 5 parts of propylene glycol, 5 parts of maleic anhydride, 13 parts of isononanoic acid, 19 parts of hexahydrophthalic anhydride, feed nitrogen and heat up to Stirring was started at 150°C, and then the temperature was raised to 230°C in steps of 10°C per hour. During the heating process, the gas phase temperature was controlled below 100°C, and the constant temperature was kept at 230°C until the sampling liquid level was transparent. After 30 minutes, slowly added 2 parts of xylene to control The reflux temperature is 225-230°C. After reflux for two hours, take a sample and test it. After passing the test, add 36 parts of xylene after cooling.

[0027] In the present invention, two different polyesters can be prepared respectively through the above two examples, and compared with other three polyesters on the market as the raw materials of the paint compositio...

Abstract

The invention discloses novel polyester and an application thereof and belongs to the field of chemistry to solve the problems that a coating on the surface of a golf ball is poor in treatment adhesive force, poor in yellowing resistance, bad in scratch resistance and the like at present. The polyester disclosed by the invention is prepared from polyol and monocarboxylic acid with a carbon number of 9 by virtue of reaction. A coating prepared by using the polyester resin can greatly promote the yellowing resistance, impact resistance and scratch resistance of the surface of the golf ball when coated on the surface of the golf ball.

Description

technical field [0001] The invention belongs to the chemical field and relates to a novel polyester and its application. Background technique [0002] Golf balls are common sports facilities, and golf ball surface treatment is also a technical difficulty. The polyester paint used on the surface of golf balls in the prior art has disadvantages such as poor adhesion, poor yellowing resistance, and poor scratch resistance. Contents of the invention [0003] The invention provides an economical and environment-friendly novel polyester and a polyester coating prepared by the same, which solves the problems of poor adhesion, poor yellowing resistance, poor scratch resistance and the like in current golf ball surface coatings. [0004] The present invention is implemented through the following technical solutions: [0005] A new type of polyester synthesized from the following substances in mass proportion: [0006] [0007] The novel polyester is used in coating components...
