Problems solved by technology

But, in above-mentioned prior art, its preparation method also utilizes other substances besides polyacrylate polymer, for example: urethane, polyvinyl chloride (PVC), acrylonitrile-butadiene rubber type polymerization substances, styrene-butadiene rubber polymers, adhesives, etc.
And some substances (for example: plasticizer) added in these prior art may also cause harm to the human body
In addition, some existing technologies also utilize nitrile rubber (Nitrile ButadieneRubber, NBR) or water-based polyurethane (also known as water-based PU); among them, the advantages of water-based polyurethane are good film-forming properties, good elasticity and good toughness, and can also make up for Polyacrylate has the disadvantage of poor anti-adhesion; however, water-based polyurethane has disadvantages such as poor heat resistance, poor alcohol resistance, and strong polar solvent and strong acid-base medium.

Embodiment

[0050] The present invention will further describe the preparation of polyacrylate solution and the process steps of preparing gloves with reference to the following examples, which are only illustrative and not limiting. Its purpose is to enable those skilled in the art to understand the content of the present invention and realize it accordingly. Regarding the claimed scope of the present invention, the scope of claims in the application shall prevail.

[0051] Dissolve 4.5 kg of sodium dodecyl sulfate (K-12) in 400 kg of water, then place it in the polymerization tank and heat it to about 55°C. At this time, pour 18 kg of ethyl acrylate into the above polymerization tank , then pour about 0.3 kg of itaconic acid, and keep stirring at a constant temperature of 63°C. The sodium lauryl sulfate of this embodiment is used as the emulsifier of emulsion polymerization.

[0052] Wherein, the ethyl acrylate in this embodiment can also be replaced by butyl acrylate, isooctyl acrylat...

Abstract

The present invention provides a composition used for manufacturing gloves comprising polyacrylate, which has glass transition temperature (Tg) under 20DEG. The composition comprises characteristicsof anti-sticking feature, alcohol resistance, anti-bacteria, anti-mildew, anti-UV, and without allergen. The gloves made by the composition can replace those made by traditional materials such as NBR,PVC, and so on. The composition used for gloves is able to apply to medical and electronics industries.

Description

technical field [0001] The invention relates to a composition, in particular to a glove composition used in industries such as medical treatment and electronics. Background technique [0002] With the development of electronics, medical and other industries, the amount of gloves required has been increasing. Therefore, for these industries, the characteristics of gloves are required, such as alcohol resistance, film forming, tear strength, and non-toxic. Allergens, anti-ultraviolet, antibacterial, anti-mildew, breathable, etc. have been valued by users in these industries. Therefore, there has been a long-standing demand from the industry for gloves with favorable properties. [0003] Generally, traditional gloves are mostly prepared from natural rubber, butyl rubber, etc., and prepared by blending two or more polymers. Formate polymer dispersions are blended, or must be formed in urethane polymer dispersions (commonly known as blended polyurethanes) to improve alcohol res...
