Abstract

The invention belongs to the technical field of latex product manufacturing, particularly relates to a light-aging-resistant latex product and a manufacturing method thereof, and solves the problems that a latex product in the prior art is easy to oxidize after being in contact with ultraviolet rays, is easy to yellow, is cracked on the surface, falls off residues at notches, generates peculiar smell and the like. In addition, the problem that a latex product easily causes skin allergy and discomfort of a small part of users is solved, and the light-aging-resistant latex product comprises the following raw materials: natural latex, nano filler, a vulcanization accelerator, polyethylene glycol dimethacrylate, ethylene glycol monostearate, butyl stearate and hexadecyl trimethyl ammonium bromide. The formula is safe and scientific, the process is simple and easy to operate, and the obtained latex product has excellent light aging resistance and oxidation resistance, can be in contact with ultraviolet rays for a long time, does not turn yellow, does not generate peculiar smell, and is good in comprehensive quality and long in service life while maintaining the excellent characteristics of ultrahigh elasticity, good biological property and the like of natural latex.

Description

technical field [0001] The invention relates to the technical field of latex product manufacturing, in particular to an anti-light aging latex product and a manufacturing method thereof. Background technique [0002] Natural rubber latex is a milky white liquid that flows directly from rubber trees, and its main component is cis-1,4-polyisoprene. In addition to rubber hydrocarbons and water, it also contains a small amount of various non-rubber substances, such as proteins, lipids, water-soluble substances, acetone-soluble substances and inorganic salts, etc. These non-rubber substances account for 5-8% of the total weight of fresh latex . The main advantage of natural rubber latex is excellent comprehensive performance, which is characterized by good film-forming performance, high wet gel strength, easy vulcanization, and the resulting products have excellent elasticity, high strength, large elongation and small creep , suitable for preparing various latex products.
