Problems solved by technology

[0004] Conventional nitrile rubber gloves produced in the prior art contain substances such as sulfur and zinc oxide, and need to undergo high-temperature vulcanization molding to produce small defects. When exposed to chemical solvents and other substances, these defects are likely to cause the risk of solvent leakage
In addition, conventional nitrile rubber gloves have poor compactness and poor corrosion resistance, and these defects easily cause the risk of solvent leakage

Abstract

The invention relates to a preparation process of acid and alkali resistant latex glove, which comprises the following steps of: immersing a pretreated hand mold into latex at a temperature of 25-27 DEG C, shaping the soaked hand mold at a temperature of 50-65 DEG C to form an adhesive film, leaching the hand mold with the adhesive film by using ammonia water with a temperature of 23-25 DEG C anda pH value of 9-10, and then drying at a temperature of 55-70 DEG C; vulcanizing at 75-90 DEG C, sequentially soaking the hand mold in cold water at a temperature not higher than 35 DEG C, chlorine water at a temperature not higher than 45 DEG C, and a potassium hydroxide aqueous solution at a temperature not higher than 45 DEG C and a pH value of 8-10, and demoulding to obtain the acid and alkaliresistant latex glove. The invention also relates to an acid and alkali resistant latex glove which is prepared by the preparation process of the acid and alkali resistant latex glove. The acid and alkali resistant latex glove has good compactness and still has excellent permeability resistance after being soaked in strong acid and strong alkali.

Description

technical field [0001] The invention relates to a heavy industry glove, more specifically, it relates to an acid and alkali resistant latex glove and a preparation process thereof. Background technique [0002] Heavy industry gloves refer to a kind of labor protection gloves used in high-intensity labor or environments with special needs. They are generally used in heavy industries, such as petrochemical, mining, etc., and will also be used in some environments with special needs. For example: laboratories, hospitals, etc. The glove emphasizes the comprehensive protection of the hands, so while it needs to have good wear resistance, tear resistance, penetration resistance and puncture resistance, it also has higher requirements for oil resistance and chemical resistance. [0003] The common practice of existing nitrile latex gloves is mainly to use single nitrile rubber latex as raw material, carry out pre-vulcanization by adding a certain amount of pre-vulcanizing agent, u...
