Problems solved by technology

[0005] Also, another problem with this type of lotion, cream or hand cream is the use of oily emollients in it, but it leaves an uncomfortable greasy feel
In addition, it may also cause the "wet phase" of the glove and the potential donning surface of the glove (that is, the inner surface in contact with the skin) to be prone to sticking, so that the glove causes the inconvenience of "donning hindrance"

Embodiment 1

[0097] Example 1 - Preparation process of coating composition layer applied to surgical gloves

[0098] The coating composition layer of the present invention is prepared by first determining the amount of each ingredient using conventional ingredient amount calculation methods. After determining the amounts of ingredients, add the total amount of water to the beaker, stirring constantly as each ingredient is added. Keep a small amount of soft water on hand to rinse the small beaker or container used to weigh the ingredients to ensure all ingredients are fully transferred to the beaker for stirring and mixing. The composition is stirred at room temperature for at least 60 minutes until a stable homogeneous solution is formed. The pH of the composition was measured with a pH meter / device, and the pH of the coating composition layer was 5.12 (the preferred final pH range is between 5.0 and 6.0).

[0099] The total solids content of the composition is measured by transferring...

Embodiment 2

[0105] Example 2 - Preparation of Coating Composition Layer on Gloves by Online Dip Coating Method

[0106] A surgical glove comprising a layer of the coating composition on the skin-contacting surface of the elastomeric layer can be exemplified by the following manufacturing process:

[0107] Uncoated surgical gloves can be prepared according to standard glove-forming techniques and equipment. For example, a glove mold is provided, and the powder-free coagulant composition is coated on the outside of the glove mold, and then dried. The mold with powder-free coagulant coating is then dipped in latex (such as natural rubber, chloroprene, nitrile, and polyisoprene) to deposit a latex film and form a glove-like layer (ie, an elastomeric layer), The latex film forming the glove-like layer (the elastomeric layer) is then dipped in hot water, followed by a brief air drying process to drip off excess moisture before entering a heated oven for curing or vulcanization. After curing...

[0108] Example 3 - Preparation of coating composition layer on gloves by offline spraying method

[0109] A surgical glove comprising a layer of the coating composition on the skin-contacting surface of the elastomeric layer can be exemplified by the following manufacturing process:

[0110] Uncoated surgical gloves can be prepared according to standard glove forming techniques and equipment. For example, a glove mold is provided and coated on the outside of the glove mold with a standard powder coagulant composition and then dried. The mold coated with a standard powder coagulant is then dipped into a latex (such as natural rubber, chloroprene, nitrile and polyisoprene) to deposit a latex film and form a glove-like layer (ie, an elastomeric layer) , the latex film forming a glove style layer is then soaked with water, followed by a brief air drying process to drip off excess moisture, followed by a calcium carbonate powder layer or a polymer coating such as polyurethane or...

Abstract

The invention discloses a skin contact elastomer product and a preparation method thereof, and the elastomer product is characterized in that a skin-friendly coating composition layer is coated on a skin contact surface (also called as a wearing surface) of an elastomer layer, the coating composition layer includes a combination of a primary water-soluble humectant having a high boiling point and a secondary water-soluble humectant having a high boiling point, and a skin protectant. The coating composition layer is used as an isolation medium between the elastomer layer and the skin, the viscosity between the surface of the elastomer layer and the skin can be reduced during wearing, a more convenient wearing effect is provided for a wearer, and the coating composition layer is activated and transferred to the skin after the wearer wears and makes contact with the skin, so that the comfort of the wearer is improved. The skin of a wearer is optimized, and a higher skin care effect is provided. The invention can be used for preparing medical gloves (such as examination gloves and surgical gloves) and non-medical gloves (such as industrial and livelihood gloves). The invention has a very wide prospect in preparation of examination gloves and surgical gloves.

Description

technical field [0001] The invention relates to an elastomer product and a preparation method thereof. It specifically relates to a skin-contacting elastomer product with skin care and skin activation effects and a preparation method thereof, and the elastomer product may be a glove. Background technique [0002] Disposable gloves, including medical gloves, are widely used as a protective measure at work, by wearing gloves to isolate hands from objects to be handled. In order to facilitate handling objects, generally disposable gloves are made of thin and elastic materials, which can provide "comfort and good fit" to the wearer's hand, allowing the wearer to wear them for a long time. However, hand sweating is a common problem for wearers due to poor air circulation in the glove due to the tight fit, and excessive hydration due to the direct fit of the glove material to the skin of the hand after prolonged wear , thereby compromising the protection provided by the stratum ...
