Embodiment 1

[0035] This embodiment provides a kind of silicone heat-insulating glove, and its preparation method is:

[0036] (1) Preparation of ultra-high viscosity liquid silica gel: Mix the main agent LSR7240A and the curing agent LSR7240B at a mass ratio of 100:3. After stirring evenly, use methyl silicone oil to prepare a viscosity of 1.2*10 4 cp's transparent liquid silica gel, the prepared transparent liquid silica gel is subjected to vacuum defoaming treatment.

[0037] (2) Pretreatment of glove embryos: put the glove embryos on the hand mold, and completely soak the glove embryos in 4% HJ-706 anti-penetration agent, take them out after soaking for 2 minutes, drip for 3 minutes, and put them into an oven at 110°C Bake for 40 minutes, and then send it to a 140°C oven for 5 minutes.

[0038] (3) Glue spraying: Make the hand mold tilt up at an angle of 30° relative to the horizontal plane in the length direction, and use the high-viscosity liquid silicone prepared in step (1) to spr...

Abstract

The invention relates to a preparation method of silica gel heat-insulation gloves. The preparation method includes a first step and a second step. The method includes the steps of step one, forming a glove silica gel heat-insulation layer; and step two, fixing a glove lining at the inner side of the silica gel heat-insulation layer, carrying out glue spraying twice by using ultrahigh-viscosity liquid silica gel when the glove silica gel heat-insulation layer is manufactured, then carrying out glue dipping once by using low-viscosity liquid silica gel, and supplementing and enhancing the previous glue spraying, so that the thickness of a glue layer is more uniform, and a glue surface is smoother. In the preparation process, proper temperature treatment is matched, so that while the heat-insulation effect is improved, the chemical resistance and the physical and mechanical strength, including puncture resistance, wear resistance, cutting resistance, tearing resistance and the like, of the prepared silica gel heat-insulation gloves can be obviously improved.

Description

technical field [0001] The invention relates to the technical field of labor protection gloves, in particular to a preparation method of silicone heat-insulating gloves. Background technique [0002] Lined long-tube silicone heat-insulating gloves are special-demand gloves. This glove is the only one that is resistant to high and low temperatures, as well as acid and alkali resistance. It can withstand minus 60°C to minus 300°C. Currently commercially available silicone gloves, although meeting the heat insulation requirements, are relatively poor in chemical resistance and physical and mechanical properties. CN108991634A discloses a multi-layer glove, which comprises an outer layer of silicone glove, and a layer of cloth glove suitable for the silicone glove is lined inside the silicone glove. The silicone gloves are lined with cloth gloves that are compatible with silicone gloves, which achieves good heat insulation and increases the wear resistance of the gloves. At the ...
