Problems solved by technology

However, there are two major problems in the product after adding ammonia: one is the odor problem, the human body is unacceptable to the smell of ammonia volatilized in the product or it may cause skin allergies, which is irritating and harmful to human health, and may also affect the export of the product; The other is a chemical problem. The vulcanization process of natural latex is a chemical cross-linking process. The presence of ammonia will cause harmful side reactions in this process, resulting in difficulty in vulcanization. It has a certain impact on the application of natural latex and the development of modification technology. limits
However, the existing technology is still difficult to ensure that the shelf life of natural latex storage is not affected

Abstract

The present invention discloses a method for preserving natural latex and a latex product prepared thereby. A natural latex is preserved by adding bamboo charcoal. A small quantity of an ammonia stabilizer, or no ammonia stabilizer, is added to the natural latex, thus achieving preservation without ammonia or with a reduced amount of ammonia and giving the preserved natural latex little or no pungency without affecting storage life. The latex product is antimicrobial, has limited pungency, and has a long storage life. Moreover, the latex product has a far-infrared function and can promote microcirculation in the human body. Further, the latex product has excellent mechanical performance, adsorption, moisture-absorption and sweat-removing functions, and the like. The excellent performances contribute to the wide application of the natural latex.

Description

technical field [0001] The invention relates to the technical field of natural latex, in particular to a method for preserving natural latex and a prepared latex product. Background technique [0002] Natural latex generally refers to natural latex, a thermoplastic synthetic resin belonging to the rubber category, which has the characteristics of high elasticity, good film-forming performance during bonding, and flexible film. In order to improve the heat resistance, durability and aging resistance of natural latex, natural latex is often vulcanized and then used as a base material. The fresh latex flowing out from the gum tree has good fluidity and a special sweet smell. Natural latex generally contains ingredients such as protein and sugar, which will solidify natural latex under the action of microorganisms or enzymes. If fresh latex is not treated in any way, it will usually undergo obvious corruption or deterioration after 6 to 12 hours. When the temperature is high, ...
