Problems solved by technology

However, due to the addition of materials such as foam plastics, these anti-vibration gloves have disadvantages such as poor grip, hard texture, insensitivity after wearing, poor air permeability, and fatigue when worn for a long time.
[0004] In addition, there are existing anti-vibration gloves made of physical foaming. Although the texture is soft and has good air permeability, many shortcomings of the above-mentioned gloves added with foam plastics have been improved, but the cushioning performance is poor and cannot be used for a long time. There is an urgent need to develop an anti-vibration glove with superior cushioning performance, long-term use and good anti-vibration function

Embodiment 1

[0024] This embodiment provides a preparation method of anti-vibration gloves, which specifically includes the following steps:

[0025] S0, preparing bead glue and dipping glue.

[0026] Specifically, the preparation method of above-mentioned bead glue comprises the steps:

[0027] a1, 1000 parts of natural rubber latex are pre-vulcanized by a sulfur vulcanization system to obtain pre-vulcanized latex. Among them, during the pre-vulcanization process, the natural latex molecular chains are partially vulcanized, and the natural latex molecules are quickly cross-linked to form a network structure. This process is carried out inside the natural latex particles, so that the natural latex corresponding Geophysical changes and chemical changes, thereby improving its physical and mechanical properties. The swelling index (that is, the Q value, representing the degree of crosslinking, the higher the Q value, the lower the degree of crosslinking) of the final prevulcanized latex is ...

Abstract

The invention relates to a preparation method of an anti-vibration glove. The method includes the following steps that S1, dotting is conducted, wherein dotting glue is used for fractioning of a palmpart of a glove blank; S2, foaming is conducted, wherein the glove blank obtained in S1 after fractioning is heated and subjected to foaming; S3, vulcanizing is performed, wherein the foamed glove blank obtained in S2 is vulcanized, an anti-vibration rubber layer is formed on the palm part of the glove blank, and the dotting glue is prepared from, by mass, 800-1200 parts of natural latex, 8-20 parts of surfactant, 10-50 parts of foaming agent and 15-60 parts of thickening agent. The foaming agent is one or the combination of more of sodium carbonate, sodium bicarbonate, phenylsulfonyl hydrazine, dinitrosopentamethylenetetramine and diazonium phenyl aniline. The anti-vibration glove prepared through the preparation method has excellent buffering performance, can be used for a long time andhas an excellent anti-vibration function.

Description

technical field [0001] The invention belongs to the technical field of labor protection products, and in particular relates to a preparation method of anti-vibration gloves. Background technique [0002] Protective gloves refer to protective products that protect workers' hands from physical, chemical, and biological factors during labor. There are many types of protective gloves. Protective gloves with various functions such as heat radiation, fire resistance and flame retardant. Among them, anti-vibration gloves are mainly used for labor protection in operations. For example, when operators need to manipulate hand-held vibration tools (such as chain saws, rock drills, electric hammers, jacks, etc.) type of work or motorcycle driver. When working, it is generally necessary to hold the vibrating tool with the human hand. The palm of the human hand will be affected by the vibration for a long time, and may be injured by the vibration, resulting in arm shake syndrome, white ...
