Embodiment 1

[0020] The method for collecting and preserving rubber comprises the following steps:

[0021] (1) rubber tree application regulator;

[0022] (2) before rubber latex is collected, stabilizer is placed in the collection vessel of rubber latex, makes latex slowly mix with stabilizer when flowing into collection vessel;

[0023] (3) After the collection of the rubber latex is completed, add a stabilizer to the latex, mix evenly, concentrate, and store.

[0024] The regulator includes the following components in parts by weight: 2 parts of ammonium molybdate, 0.5 part of ammonium chloride, 0.12 parts of borax, 1 part of glycerin, and 17 parts of ethephon stock solution with a content of 40%.

[0025] The stabilizer includes the following components in parts by weight: 10 parts of potassium ferrocyanide, 7 parts of sodium metabisulfite, 0.5 parts of sodium lauryl sulfate, 3 parts of chlorobutanol, and 5 parts of sodium carbonate.

[0026] The retaining agent includes the followi...

Embodiment 2

[0028] The method for rubber collection and property preservation comprises the following steps: the same as in Example 1.

[0029] The regulator includes the following components in parts by weight: 3 parts of ammonium molybdate, 1 part of ammonium chloride, 0.25 parts of borax, 3 parts of glycerin, and 20 parts of ethephon stock solution with a content of 60%.

[0030] The stabilizer includes the following components in parts by weight: 12 parts of potassium ferrocyanide, 5 parts of sodium metabisulfite, 1.5 parts of sodium lauryl sulfate, 1 part of chlorobutanol, and 8 parts of sodium carbonate.

[0031] The retaining agent includes the following components by weight: 14 parts of sodium sulfite, 2 parts of methyl p-hydroxybenzoate, 0.1 part of calcium hydroxide, 2.5 parts of sodium silicate pentahydrate, 2 parts of chitosan, 12 parts of citric acid , 7 parts of vitamin C, 15 parts of sodium benzoate, 1.2 parts of potassium sorbate, 3 parts of lemon yellow, 10 parts of lecit...

Embodiment 3

[0033] The method for rubber collection and property preservation comprises the following steps: the same as in Example 1.

[0034] The regulator includes the following components in parts by weight: 2.5 parts of ammonium molybdate, 0.6 parts of ammonium chloride, 0.20 parts of borax, 2 parts of glycerin, and 18 parts of ethephon stock solution with a content of 50%.

[0035] The stabilizer includes the following components in parts by weight: 11 parts of potassium ferrocyanide, 6 parts of sodium metabisulfite, 0.8 parts of sodium lauryl sulfate, 2 parts of chlorobutanol, and 6 parts of sodium carbonate.

[0036] The retaining agent includes the following components by weight: 11 parts of sodium sulfite, 3 parts of methyl p-hydroxybenzoate, 0.7 parts of calcium hydroxide, 1.6 parts of sodium silicate pentahydrate, 5 parts of chitosan, and 11 parts of citric acid , 6 parts of vitamin C, 12 parts of sodium benzoate, 1 part of potassium sorbate, 4 parts of lemon yellow, 9 parts o...

Abstract

The invention relates to the field of rubber, in particular to a method for collecting and preserving rubber. This method is firstly treated with a regulator to stimulate rubber tree degumification and at the same time reduce the content of fungi from the source, use stabilizers and retaining agents in stages, so that the latex is fully protected when it flows out from the tree, and the rubber latex is maintained good performance. The method is simple to operate, and the rubber latex obtained after being treated by the method of the invention still maintains good appearance properties such as good color and smell, has low volatile fatty acid value, and does not appear to be rotten.

Description

technical field [0001] The invention relates to the field of rubber, in particular to a method for collecting and preserving rubber. Background technique [0002] In addition to rubber hydrocarbons, rubber latex also contains non-rubber substances such as sucrose and protein. The supply of sucrose in latex tubes of gum tree is closely related to the yield of natural latex, but sucrose in latex is the main carbon source for microbial metabolism. Microbes decompose sucrose in natural rubber latex through their own hydrolytic enzymes, and produce volatile fatty acids such as formic acid, acetic acid, propionic acid, etc., which lower the pH value of natural rubber latex and destroy the stability of latex, thus causing rubber to deteriorate easily. Therefore, reducing the sucrose content in natural latex can effectively inhibit the metabolic activity of microorganisms, control the formation of volatile fatty acids, and improve the stability of natural latex. After centrifugal ...
