Abstract

The invention relates to a preparation method of silicone heat-insulating gloves, which comprises step 1 and step 2; step 1 forms a silicone heat-insulation layer for gloves, and step 2 fixes a layer of glove lining inside the silica gel heat-insulation layer; The silicone heat insulation layer uses ultra-high viscosity liquid silica gel to spray glue twice, and then conducts a dipping of low-viscosity liquid silica gel to supplement and strengthen the previous spray glue, so that the thickness of the glue layer is more uniform and the glue surface is smoother. . During the preparation process, with appropriate temperature treatment, the prepared silicone heat-insulating gloves can significantly improve the chemical resistance and physical and mechanical strength of the gloves while improving the heat insulation effect, including puncture resistance, wear resistance, and cut resistance. , tear resistance and other properties.

Description

technical field [0001] The invention relates to the technical field of labor protection gloves, in particular to a preparation method of silicone heat insulation gloves. Background technique [0002] The lined long-tube silicone heat-insulating glove is a special-purpose glove. This glove is the only glove that has both high and low temperature resistance and acid and alkali resistance, and can withstand minus 60 ℃ to minus 300 ℃. At present, the commercially available silicone gloves meet the thermal insulation requirements, but their chemical resistance and physical and mechanical properties are relatively poor. CN108991634A discloses a multi-layered glove, comprising an outer layer of silicone gloves, and the inner layer of the silicone gloves is lined with a layer of cloth gloves suitable for the silicone gloves. The silicone gloves are lined with cloth gloves that are compatible with the silicone gloves, which achieves a good heat insulation effect and increases the we...
