Abstract
The invention discloses a kind of anti-condensation antistaling agent of natural rubber cream and its preservation methods, the anti-condensation antistaling agent of the natural rubber cream is a kind of no ammonia preservative agent, its raw material includes potassium sulfate, sodium tripolyphosphate, sodium carbonate, five hydrated sodium silicates, citric acid and sodium benzoate, butyl p-hydroxybenzoate is not used in the anti-condensation antistaling agent of the natural rubber cream, it replaces and has selected sodium tripolyphosphate, not only maintain the flora inhibiting effect of the anti-condensation antistaling agent of natural rubber cream, also it is poor to solve butyl p-hydroxybenzoate water solubility, and the problem of easily agglomerating after causing the latex resting period longer；It in addition, sodium hydrogensulfite is wherein replaced with potassium sulfate, good water solubility, and can be improved the scope of restraining fungi of anti-condensation antistaling agent, while eliminating the heavier problem of antistaling agent smell caused by sodium hydrogensulfite addition；By reducing the dosage of sodium carbonate, cost of material is greatly reduced.The cost of the antistaling agent is low, nonhazardous, pollution-free, can effectively improve rubber quality.
Description
Technical field
The invention belongs to field of rubber technology, in particular to the anti-condensation antistaling agent of a kind of natural rubber cream and its preservation method.
Background technique
Rubber is a kind of important raw material of industry, is known as the four big raw materials of industry with steel, petroleum, coal.Rubber is due to tool
There are distinctive high resiliency and good physical mechanical property and electrical insulation capability, purposes extremely wide.Therefore the consumption of rubber
It is very big.Conventionally used rubber includes natural rubber and synthetic rubber.Current global demand year up to 20,000,000 tons,
12,000,000 tons of middle asynthetic rubber, 8,000,000 tons of natural rubber.But asynthetic rubber can not replace natural rubber.China
The world natural rubber yield Zhi Zhan 7%, and demand accounts for 22% of the world or more.
Natural rubber is the rubber extracted from plant containing glue.It is a kind of milky from the collected latex of rubber tree
Liquid, appearance are similar to milk；It is the product of rubber tree biosynthesis, and ingredient is sufficiently complex, except containing rubber hydrocarbon and water
Except, the nonrubber materials such as protein also rich in, carbohydrate, lipides, inorganic salts, enzyme, under the action of bacterium and enzyme,
It is easy to and will soon be putrid and deteriorated, to be impacted to product quality and economic benefit.
For a long time, to prevent fresh latex volatilization acid value from increasing in rubber production, not corrupt solidification before holding is processed, with
And the stability of processing, it is common practice to antistaling agent containing ammonia be added after collection.But since ammonia has strong sharp aroma, have
Corrosivity seriously affects work production environment, endangers the health of worker, pollutes environment, and it is solidifying to will increase later period latex
Gu increasing production cost with acid amount.Accordingly, it is desirable to provide a kind of antistaling agent safe and non-toxic, cheap, easy to use.
Summary of the invention
The purpose of the present invention is to provide a kind of anti-condensation guarantors of natural rubber cream safe and non-toxic, cheap and easy to use
Fresh dose, the quality of environmental type natural rubber can be greatly improved using the antistaling agent.Sour dosage during reducing simultaneously, accordingly
Reduce production cost.
The purpose of the present invention is what is be achieved through the following technical solutions:
A kind of anti-condensation antistaling agent of natural rubber cream, raw material include potassium sulfate, sodium tripolyphosphate, sodium carbonate, five hydrated sodium silicates,
Citric acid, sodium benzoate, the weight part ratio of each raw material are as follows:
1-4 parts of potassium sulfate
1-2 parts of sodium tripolyphosphate
1-3 parts of sodium carbonate
Five 4-10 parts of hydrated sodium silicates
1-5 parts of citric acid
1-5 parts of sodium benzoate.
Further preferred scheme, the weight fraction ratio of each raw material are as follows:
2-2.5 parts of potassium sulfate
2-4 parts of sodium tripolyphosphate
1-2 parts of sodium carbonate
Five 6-8 parts of hydrated sodium silicates
2-3 parts of citric acid
1-3 parts of sodium benzoate.
Another aspect of the present invention:
A kind of preservation method of natural rubber cream uses a kind of anti-condensation antistaling agent of natural rubber cream, institute in the preservation method
The anti-condensation antistaling agent of natural rubber cream stated is by potassium sulfate, sodium tripolyphosphate, sodium carbonate, five hydrated sodium silicates, citric acid, benzoic acid
Sodium composition, the weight part ratio of each raw material are as follows:
1-4 parts of potassium sulfate
0.1-2 parts of sodium tripolyphosphate
1-5 parts of sodium carbonate
Five 4-10 parts of hydrated sodium silicates
1-5 parts of citric acid
1-5 parts of sodium benzoate；
The preservation method comprises the steps of
A. by potassium sulfate, sodium tripolyphosphate, sodium carbonate, five hydrated sodium silicates, citric acid, sodium benzoate according to above-mentioned weight
Portion rate is uniformly mixed, and the anti-condensation antistaling agent of natural rubber cream is made；
B. the anti-condensation antistaling agent of natural rubber cream of above-mentioned preparation is added in 1000 ~ 1500 parts of natural rubber cream；
C. it will be saved under the natural rubber cream room temperature that the anti-condensation antistaling agent of natural rubber cream is added.
The present invention having the beneficial effect that compared with prior art
1, the anti-condensation antistaling agent of natural rubber of the present invention cream, feature are no ammonia, and formula material is non-stimulated, healthy nothing
Poison has no toxic and side effect to human body, and is more suitable the demands of the products such as bedding, mother and baby's articles, and downstream producer can be made to remove from
Deamination technique reduces waste water and gas discharge, reduces whole production cost；
2, in the anti-condensation antistaling agent of heretofore described natural rubber cream, butyl p-hydroxybenzoate is free of, replace selection
Sodium tripolyphosphate, this not only maintains the flora inhibiting effect of no ammonia preservative agent, while also solving butyl p-hydroxybenzoate
It is water-soluble poor, and after causing the latex resting period longer the problem of easy agglomeration；
3, in the anti-condensation antistaling agent of heretofore described natural rubber cream, by reducing the dosage of sodium carbonate, original is greatly reduced
Expect cost；
4, in the anti-condensation antistaling agent of natural rubber of the present invention cream, substitute sodium hydrogensulfite using potassium sulfate, solve because
The addition of sodium hydrogensulfite, and the problem for keeping antistaling agent smell heavier, meanwhile, the good water solubility of potassium sulfate can improve product suppression
Bacterium range.
