Abstract

The invention belongs to the technical field of gloves, and particularly relates to a silica gel glove and a preparation method thereof. The preparation method of the silica gel glove comprises the following steps: coating the outer surface of a glove-shaped fabric liner with an organic silicon emulsion, preheating the fabric liner coated with the organic silicon emulsion, and preserving heat to obtain a prototype glove; and spraying glue on the surface of the prototype glove, and curing to obtain the silica gel glove. The organic silicon emulsion is a cationic hydroxyl silicone oil emulsion, a nonionic hydroxyl silicone oil emulsion or a methyl hydrogen-containing silicone oil emulsion; the silica gel used in the glue spraying process is addition type liquid silicone rubber. According to the invention, the water repellent is not required to be used, and the fabric liner is coated with the organic silicon emulsion, so that the subsequent addition type liquid silicone rubber is prevented from permeating into the fabric liner; the addition type liquid silicone rubber is silica gel with triethoxysilane as the main component, and the viscosity is adjusted by adjusting the molecular weight of the addition type liquid silicone rubber, so that the use of benzene or toluene organic solvents is avoided, and the glove is non-toxic and environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of gloves, and in particular relates to a silicone glove and a preparation method thereof. Background technique [0002] Silicone gloves, also known as silicone insulation gloves, silicone microwave oven gloves or silicone anti-scald gloves, have waterproof and heat-resistant protective properties. The preparation method of the currently commercially available silicone gloves is generally to carry out water-repellent treatment to the fabric liner, and then coat liquid silicone and then cure or vulcanize. In this method, the water-repellent agents used in the water-repellent treatment are divided into non-fluorine-based water-repellent agents and fluorine-based water-repellent agents. Most of the fluorine-based water-repellent agents with better water-repellent effects do not meet environmental protection requirements ( Water repellent has been banned in Europe), even after secondary cleaning, harmful residu...
