Abstract

The invention discloses an anti-ultraviolet treatment method for rubber gloves. The anti-ultraviolet treatment method for the rubber gloves comprises the following steps: copolymerizing an inorganic filler and a polyester copolymer containing a side group of hindered amines in an ultrasonic device under the action of other auxiliary agents to form an anti-ultraviolet composite coating micro-latexcoating, then increasing the surface adsorption force of the coating by the variable-temperature pre-treatment, coating on both sides of the rubber gloves, carrying out a post-finishing treatment process for consolidation after coating, thereby effectively improving the absorption of the rubber gloves for medium wavelength ultraviolet and increasing the ability of the rubber gloves for resisting the ultraviolet to reduce the aging speed.

Description

technical field [0001] The invention relates to a method for preparing functional gloves, in particular to an anti-ultraviolet treatment method for rubber gloves. Background technique [0002] Rubber gloves are widely used in the catering industry, electronics industry, hospitals, laboratories and other places. Because rubber itself is easy to absorb and oxidize, it is prone to aging, and a large part of the aging is also caused by ultraviolet radiation, especially In view of the relatively large proportion of mid-wavelength ultraviolet rays in sunlight, the absorption is poor, which will cause rapid aging in the long run. [0003] At present, a certain amount of anti-ultraviolet additives is generally added to the glove matrix, but these substances themselves have poor compatibility with the glove matrix material, are easy to dissolve, and have limited long-term anti-ultraviolet effect. Contents of the invention [0004] Purpose of the invention: In order to solve the pr...
