Embodiment 1

[0097] A composite dumbbell material, comprising:

[0098] The inner layer material includes metal powder and high molecular polymer, and the inner layer material is used to prepare the core body of the dumbbell;

[0099] a middle layer material, which includes epoxy resin, vinyl acetate, polyaspartic acid, plasticizer and organic solvent, and the middle layer material is used to form an intermediate protective layer on the surface of the core body;

[0100] and an outer layer material, which includes a film-forming material and a self-cleaning antibacterial agent, and the outer layer material is used to form a self-cleaning antibacterial layer on the middle protective layer.

[0101] (1) The inner layer material includes the following components in parts by weight:

[0102]

[0103] Among them, the metal powder of the inner layer material is a mixture of iron powder and lead powder, the mass ratio of iron powder and lead powder is 6:4, and the high molecular polymer is a ...

Embodiment 2

[0124] This embodiment is basically the same as Embodiment 1, and the differences are mainly listed below, in this embodiment:

[0125] The mass ratio of the film-forming material and the self-cleaning antibacterial agent in the outer layer material package is 100:3.

[0126] The self-cleaning antibacterial agent is prepared by the following method:

[0127] 1) Take 250ml of the ethanolic solution of aluminum sec-butoxide with a concentration of 1mol / L, add 0.05mol hexadecyltrimethylammonium bromide, stir 5min at 65°C, add 0.5mol / L ammonium carbonate solution under stirring 200ml, adjust the pH value to 9 with ammonia water, continue to stir the reaction for 40min, after the reaction, filter, discard the filtrate, precipitate and wash, vacuum dry at 55°C for 2 hours, then roast at 520°C for 8 hours, the product is ground to obtain mesoporous alumina carrier;

[0128] 2) Add the mesoporous alumina carrier into 300ml of deionized water, disperse by ultrasonic for 25min, add 0....

Embodiment 3

[0131] This embodiment is basically the same as Embodiment 1, and only the differences are listed below, in this embodiment:

[0132] The mass ratio of the film-forming material and the self-cleaning antibacterial agent in the outer layer material is 100:5.

Abstract

The invention discloses a composite dumbbell material, which comprises: an inner layer material, which comprises a metal powder material and a high-molecular polymer, and is used for preparing a core body of a dumbbell; the middle layer material comprises epoxy resin, vinyl acetate, polyaspartic acid, a plasticizer and an organic solvent; the outer layer material comprises a film forming material and a self-cleaning antibacterial agent, and the outer layer material is used for forming a self-cleaning antibacterial layer on the middle protective layer. According to the dumbbell, the core body of the dumbbell can be isolated from the external environment through the middle protection layer, the core body is sealed and protected, and the core body is prevented from rusting or accelerated aging due to direct contact with air; due to the addition of the self-cleaning antibacterial agent, the self-cleaning antibacterial layer can provide continuous antibacterial performance and self-cleaning performance; and when in an environment where bacteria are easy to breed, such as hand sweating or humid air, the silver ions and the nano titanium dioxide can be promoted to be properly and quickly released, so that the self-adaptive enhanced antibacterial and self-cleaning effects can be realized.

Description

technical field [0001] The invention relates to the technical field of dumbbell preparation, in particular to a composite dumbbell material. Background technique [0002] Dumbbells are a common fitness equipment. Dumbbells are usually made of metal materials such as iron and steel and some polymer materials. For example, the composite material for preparing dumbbells disclosed in Patent 11438357B and the method for making dumbbells using the same material are disclosed in Patent 02746579A A composite material dumbbell and barbell product and its manufacturing method are disclosed. Existing dumbbells generally have the following defects: the surface of the dumbbell is in direct contact with the user's hand and is soaked in sweat, which easily breeds bacteria, which poses the risk of endangering the user's health, and the sweat also easily causes the internal material of the dumbbell to be damaged, resulting in a shortened service life. . [0003] Therefore, it is now necess...
