Technical Field

The invention relates to an anti-static latex glove, and belongs to the field of production and preparation of latex products.

Background

With the development of science and technology, the environmental requirements in industrial production are higher and higher, and the generation of static electricity is required to be avoided in many production processes. Especially in the electronic industry, because static electricity can damage electronic elements and affect the product quality, the traditional gloves do not have the anti-static function and cannot eliminate the static electricity on the working environment and operators.

Chinese patents CN105462006A, CN103932432A, CN104621800A, and CN107936318A all disclose anti-static latex gloves, which can solve the problem of anti-static performance to a certain extent, but these anti-static gloves all adopt a chlorine washing process during the cleaning process, so that there may be chlorine residue on the surface of the gloves, and chlorine has strong oxidizing property and damages precise electronic components.

Disclosure of Invention

The invention aims to overcome the defects in the prior art and provides an anti-static latex glove and a manufacturing method thereof.

The technical scheme adopted by the invention is as follows:

the antistatic latex gloves comprise the following raw materials in parts by weight:

The invention has the beneficial effects that: the chlorine-free element greatly reduces the oxidation of the gloves to precise electronic products, the antistatic performance of the latex gloves is enhanced by 20-50%, the surfaces of the gloves are treated by PU (polyurethane), the gloves are convenient to wear, the powder amount is reduced to below 2 mg, and the purpose of protecting products, human hands and clean room environment is achieved.

Detailed Description

The invention is further illustrated by the following examples.

The gloves sold in the market at present have poor antistatic performance in the field of high-end electronic products, contain halogen, and are easy to damage skin and oxidize electronic components in the using process. Therefore, there is a need for an antistatic glove which is free of halogen and strong in antistatic property, and can protect skin and electronic components.
