Abstract

The invention relates to a normal temperature preservative for natural rubber latex. In order to solve technical problems, the invention adopts the technical scheme that the formula of the normal temperature preservative for the natural rubber latex comprises the following components in part by weight: 1 to 1.5 parts of potassium ferrocyanide, 0.3 to 0.5 part of sodium pyrosulfite, 0.1 to 0.3 part of ethylparaben, 0.2 to 0.3 part of propylparaben, 0.3 to 0.5 part of sodium hydrogen carbonate and 1 to 3 parts of citric acid. After the components are compounded into the formula, the formula is added into 800 to 1,100 parts of natural rubber latex at one time, and the mixture is fully stirred to dissolve and stored in a container at normal temperature. The normal temperature preservative has no toxicity or harm, does not pollute the environment, improves the quality and the dry content of the natural rubber latex, and is convenient to use and low in cost.

Description

technical field [0001] The invention relates to a normal-temperature antistaling agent for natural rubber latex. Background technique [0002] The strength or weakness of a country determines the four major industries of steel, rubber, coal and oil. my country's rubber production accounts for only 7% of the world's total, while demand accounts for more than 20%. In the world today, ammonia water is used to preserve the freshness of natural rubber latex. Ammonia water is not only poisonous and pollutes the environment, but also reduces the quality and dry content of rubber latex, which is not conducive to industrial production. Contents of the invention [0003] The purpose of the present invention is to provide a kind of room-temperature antistaling agent of natural rubber latex. [0004] The technical scheme that the present invention adopts for solving its technical problem is: [0005] The normal temperature antistaling agent formula of natural rubber latex is as fol...
