Problems solved by technology

[0003] General polyorganosiloxane mixtures have problems such as poor fluidity and short operating time, which cannot be applied to the preparation of silicone gloves by leaching
In addition, although liquid silicone rubber is disclosed in the prior art, it is not reported that it is used to make silicone gloves by leaching, such as a liquid silicone rubber disclosed in a Chinese patent application (publication number: CN103450840A), including silica gel, diluent and hardening agent. Although it has a certain fluidity and soft colloid after curing, it is specially used for rubber-planted gloves, and directly uses silica gel as the main raw material, and the effect of good fluidity is achieved by adding a diluent. Not applicable by leaching
In the prior art, it is disclosed that polyorganosiloxane is directly used as a raw material, but its application in silicone gloves has not been reported.

Abstract

The invention relates to a manufacture method of silica gel gloves and a polysiloxane mixed liquor, belongs to the technical field of glove materials and products and aims at solving the problems of short operating time of raw materials and poor low-temperature resistance of the existing silica gel gloves. The mixed liquor comprises polysiloxane containing vinyl and polysiloxane containing a Si-H bond, and also comprises 0.3%-1.2% of platinum catalyst and 1.0%-3.0% of methyl vinyl cyclotetrasiloxane, wherein the weight ratio of the polysiloxane containing vinyl to the polysiloxane containing the Si-H bond is (8-12):1. The mixed liquor is taken as the raw material, and the silica gel gloves are prepared through steps of molding by pouring the pulp and / or steeping the pulp, vulcanizing and post-processing. The method can prolong the operating time of the raw material, so that the gloves resist high and low temperature; the method realizes preparation of the silica gel gloves by pouring and steeping, so that the gloves have flexible, comfortable and waterproof effects; when the method is used for preparing the silica gel gloves with linings, the linings have high bonding strength and are not easy to strip off.

Description

technical field [0001] The invention relates to a method for making silicone gloves and a polyorganosiloxane mixed solution, belonging to the technical field of glove materials and products. Background technique [0002] Silicone gloves have the characteristics of high temperature resistance, low temperature resistance, non-toxic and environmental protection, and are widely used in various fields. At present, the production method of silicone gloves mainly adopts injection molding or compression molding. Injection-molded silicone gloves, such as a silicone glove disclosed in a Chinese patent (authorized announcement number: CN2925150Y), are integrally formed by injection molding. The main cover of the little finger and the secondary cover for the thumb are set opposite to the main cover of the glove body. Although the silicone glove has the advantages of water resistance and high temperature resistance, it has the problem of poor air permeability, and often It will feel un...
