Benefits of technology

The patent describes a type of glove that has high resistance to heat and moisture, and is resistant to deformation when stretched or compressed. The glove has a unique design with a first layer and a second layer that join together at the edge to form an open end. The first layer and second layer are made of a silicone composition, with at least one of them containing reinforced material. The reinforced material can be made of various materials such as polyester, polyamide, polyvinyl alcohol, carbon, glass, or steel. The silicone composition can also contain other additives such as colorants, cross-linking agents, catalysts, fillers, and plasticizers. The curing process involves placing the layers in a mold and curing them at an elevated temperature. The resulting glove has a unique design and provides high resistance to heat and moisture.

Problems solved by technology

Nevertheless, the projective effects of the existing gloves are far from satisfactory.
This cannot be done if the gloves are slippery.
Because gloves are usually made of flexible materials, they are usually subject to undue deformation or even destruction when external forces are applied, which causes inconveniences to the users and shortens the lives of the gloves.

example 1

[0095]Example 1 is an embodiment of the silicone compositions disclosed herein. Example 1 was prepared by mixing or milling a mixture of 24.25 wt. % of ZY7821, 24.25 wt. % of QT910U, and 48.5 wt. % of ZY7817 (all of the three ingredients are silicone rubbers; obtained from Shin-Etsu Chemical Co., Ltd., Tokyo, Japan); 1.5 wt. % of SKH-158B (a cross-linking agent; obtained from Shin-Etsu Chemical Co., Ltd., Tokyo, Japan); and 1.5 wt. % of SA924, SB330, and SB400 (all are colorants and were obtained from Holland Colours NV, Apeldoorn, the Netherlands). All the wt. % amounts are based on the total weight of Example 1.

example 2

[0096]Example 2 is an embodiment of the silicone gloves disclosed herein. Example 1 was made into a flat sheet with a thickness of about 2 mm for use in Example 2. Four glove-shaped pieces of an identical glove shape were carved out from the flat sheet, each of which weighed about 55 g. A glass-fiber sheet corresponding to the shape of the glove piece with a size slightly smaller than the glove piece was placed on top of one glove piece. Then, another glove piece was placed on top of the glass-fiber sheet, producing a first layer of the glove. Then, the same steps were repeated to produce a second layer of the glove. The molding machine is commercially available from X. L. B. Rubber Machinery Corporation, Guangzhou, Model No. XLS-1. The mold had 2 tooling cavities and each comprised an upper portion, a lower portion and a mandrel between the upper portion and the lower portion. The first layer of the glove was placed on the upper side of the mandrel; the second layer of the glove wa...

Abstract

The invention relates to silicone articles, specifically molded silicone gloves, and methods of making of the silicone gloves. The silicone gloves may optionally comprise a reinforced material. The silicone gloves may have heat resistance and slip resistance and can retain shape after deformation.

Description

PRIOR RELATED APPLICATIONS[0001]This application claims priority to copending U.S. Provisional Patent Application Ser. No. 60 / 983,184, filed Oct. 27, 2007, which is incorporated herein by reference in its entirety.FEDERALLY SPONSORED RESEARCH STATEMENT[0002]Not applicable.REFERENCE TO MICROFICHE APPENDIX[0003]Not applicable.FIELD OF THE INVENTION[0004]This invention relates to silicone gloves which comprises a reinforced material and methods of making the same. The silicone gloves may have high resistances to heat and steam and have high slip resistance.BACKGROUND OF THE INVENTION[0005]Gloves can be used to protect hands from harmful substances, heat, moisture, cuts, burns, or injuries. Numerous types of gloves have already been proposed, differing in shape and / or in the materials from which they are made. Nevertheless, the projective effects of the existing gloves are far from satisfactory.[0006]Another desirable function of gloves is slip resistance. This is because people usually...
