Abstract

The present invention relates to the technical field of rubber chemicals, and particularly relates to a natural rubber latex preservative. The rubber latex preservative comprises the following raw materials in parts by weight: 0.2-0.5 part of sodium metabisulfite, 0.1-0.5 part of butyl p-hydroxybenzoate, 4-10 parts of sodium bicarbonate, 1-5 parts of sodium benzoate and 1-3 parts of citric acid. Object of the present invention is to provide a safe, environmentally-friendly, low-price, easy-to-use natural rubber latex preservative.

Description

technical field [0001] The invention relates to the technical field of rubber chemical industry, in particular to a natural rubber latex preservative. Background technique [0002] Rubber is an important industrial raw material, known as the four major industrial raw materials along with steel, petroleum, and coal. Rubber has a wide range of uses due to its unique high elasticity, good physical and mechanical properties and electrical insulation properties. Therefore, the consumption of rubber is very large. Commonly used rubbers include natural rubber and synthetic rubber. At present, the world's annual demand reaches 20 million tons, including 12 million tons of synthetic rubber and 8 million tons of natural rubber. But synthetic rubber cannot replace natural rubber. my country's natural rubber production accounts for only 7% of the world's total, while its demand accounts for more than 22% of the world's total. Natural rubber is rubber extracted from gum-containing p...
