Embodiment 1

[0010] The biological curing agent formula of natural rubber latex is as follows by weight percentage:

[0011] Water 0.5, glacial acetic acid 8, citric acid 0.3, carbocisteine ​​0.009.

[0012] After the above ingredients are compounded into a square, add 500 to 800 parts of natural rubber latex at one time, stir well and evenly, and then solidify.

Embodiment 2

[0014] The biological curing agent formula of natural rubber latex is as follows by weight percentage:

[0015] Water 1.25, glacial acetic acid 9, citric acid 0.5, carbocisteine ​​0.015.

[0016] After the above ingredients are compounded into a square, add 500 to 800 parts of natural rubber latex at one time, stir well and evenly, and then solidify.

Embodiment 3

[0018] The biological curing agent formula of natural rubber latex is as follows by weight percentage:

[0019] Water 2.0, glacial acetic acid 10, citric acid 0.7, carbocisteine ​​0.02.

[0020] After the above ingredients are compounded into a square, add 500 to 800 parts of natural rubber latex at one time, stir well and evenly, and then solidify.

Abstract

The invention relates to a biological curing agent for natural rubber latex. A formula of the biological curing agent comprises the following components in parts by weight: 0.5-2.0 parts of water, 8-10 parts of glacial acetic acid, 0.3-0.7 part of citric acid and 0.009-0.02 part of carbocisteine. The biological curing agent is prepared by the following steps of: after the components are compounded into the formula, adding 500-800 parts of natural rubber latex, fully stirring to be uniform and curing. The biological curing agent has the beneficial effects that not only are no toxicity and harm caused, but also the environment is not polluted, the molecular structure of the rubber is not damaged, and the quality and the dry content of the natural rubber latex are improved; and the use is convenient and the cost is reduced.

Description

technical field [0001] The invention relates to a biological curing 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%. All the curing of natural rubber latex in the world today uses toxic formic acid or sulfuric acid, which not only pollutes the environment, but also reduces the quality of latex and the dry content, which is unfavorable for industrial production. Most of the preservation of natural rubber latex in the world today uses ammonia water. Ammonia water is not only poisonous, but also seriously pollutes the air and the environment in which human beings live. Toxic and side effects Ammonia has been used in natural rubber for hundreds of years, and it is still used in succession today. Still adopt formic acid as natural latex curing ag...
