Description
Technical field
The invention belongs to the latex product manufacture field, the agent of particularly a kind of natural emulsion biological curing contains in the raw material of described natural emulsion biological curing agent that amino naphthalenes disulfonic acid, citric acid, bisulfite are received, carbamate, Sorbic Acid.
Background technology
Rubber is a kind of important industrial raw material, is known as four big industrial raw material with iron and steel, oil, coal.Rubber is owing to have distinctive snappiness and good physical and mechanical properties and electrical insulation capability, and purposes is very extensive.Therefore the consumption of rubber is very big.Usually used rubber comprises natural rubber and synthetic rubber.Present global demand year reaches 2,000 ten thousand tons, and wherein the asynthetic rubber is 1,200 ten thousand tons, 8,000,000 tons of natural rubbers.But the asynthetic rubber can't replace natural rubber.The natural rubber output of China only accounts for 7% of the world, and demand accounts for more than 22% of the world.
Effusive liquid when natural emulsion (also claiming caoutchouc latex) is the rubber tree rubber tapping is creamy white, and solid content is 30%～40%, 1.06 microns of rubber size average out to.Fresh natural emulsion contains rubber constituent, water, protein, natural resin, carbohydrate, ash and grades.Natural emulsion is mainly used in makes sponge product, tubed goods and dipped goods.
The chemical property of natural emulsion is to see acid cure.In the production process of natural rubber, will add a certain proportion of acid reagent in natural emulsion can produce crosslinking reaction and make the elastic solid material of its solidify out into---natural rubber, thisly can make material that latex solidifies rapidly, be also referred to as solidifying agent in peptizer.
The most of ammoniacal liquor that adopts of the curing of natural latex rubber in the world today, ammoniacal liquor is not only toxic, severe contamination the overall situation of air and human survival, and the natural rubber milk-quality is descended, drc also reduces, and is unfavorable for suitability for industrialized production.Toxic side effect ammoniacal liquor has been used one-hundred-year history on natural rubber, still using successively so far.Also have at present and adopt formic acid, but formic acid had both injured rubber, contaminate environment again, also nonideal natural emulsion solidifying agent as the natural emulsion solidifying agent.
So, need on the market a kind of adopt biological products be main acidic substance, nontoxic to human body and environmental safety, can guarantee the solidifying agent natural rubber quality of item, easy to use.
Summary of the invention
The object of the present invention is to provide a kind of solidifying agent, contain in the raw material of described solidifying agent that amino naphthalenes disulfonic acid, citric acid, bisulfite are received, carbamate, Sorbic Acid.
The objective of the invention is to be achieved through the following technical solutions:
The agent of a kind of natural emulsion biological curing contains in the raw material of described natural emulsion biological curing agent that amino naphthalenes disulfonic acid, citric acid, bisulfite are received, carbamate, Sorbic Acid, and above-mentioned each raw materials in part by weight ratio is:
Amino naphthalenes disulfonic acid 1～1.5, citric acid 3～5, bisulfite receive 1～2.5, carbamate 1～2, Sorbic Acid 1～2.
The preparation method of described natural emulsion biological curing agent comprises the following step:
With described amino naphthalenes disulfonic acid, citric acid, bisulfite receive, carbamate, Sorbic Acid mix according to said ratio, makes the agent of natural emulsion biological curing.
The objective of the invention is to realize by following another technical scheme:
The curing of a kind of natural emulsion biological curing agent contains in the raw material of described natural emulsion biological curing agent that amino naphthalenes disulfonic acid, citric acid, bisulfite are received, carbamate, Sorbic Acid, and above-mentioned each raw materials in part by weight ratio is:
Amino naphthalenes disulfonic acid 1～1.5, citric acid 3～5, bisulfite receive 1～2.5, carbamate 1～2, Sorbic Acid 1～2;
Described curing comprises the following step:

B. described natural emulsion biological curing agent is added in the natural emulsion of 900-1000 weight part, fully stir, obtain the solidified natural emulsion.
Natural rubber latex biological curing agent principle of the present invention is as follows: the present invention is the acidic formulation (vegetable acid) that biological raw material is made, and it makes the latex quick solidifying, and rubber quality improves, and is free from environmental pollution.
Described sodium bisulfite is a kind of weak base of white crystals type powder, can be used as reductive agent, sanitas, sterilizing agent and SYNTHETIC OPTICAL WHITNER, it can play neutralizing effect to the acid that generates in the latex, can also suppress the growth of bacterium and prevent the oxidation of latex, sodium bisulfite also has good bleaching action simultaneously, has dual function anticorrosion and bleaching;
Described citric acid is colourless translucent crystal, has good germicidal action;
Described Sorbic Acid is the food preservatives of using always, has to prevent the rotten effect of turning sour, extending the shelf life;
Described amino naphthalenes disulfonic acid, these two kinds of materials of carbamate play good solidification in weakly alkaline material, natural rubber latex is a weakly alkaline liquid, and pH value is 7.2, the above two kinds of materials of institute run into alkaline liquid, solidification effect is very fast, also has no side effect, and does not destroy rubber quality.
More than various raw materials synergy, for good effect has been played in the curing of caoutchouc latex.
Compared with the prior art the present invention has following advantage:
1, do not contain ammonia in the natural emulsion biological curing of the present invention agent, nonirritant, healthy nontoxic, human body is had no side effect.
2, each raw material sources is extensive, with low cost in the natural emulsion biological curing of the present invention agent, and manufacturing process is simple, and is easy to use, convenient transportation.
3, natural emulsion biological curing of the present invention agent is effective, the natural rubber Products Quality height that makes.
4, the raw material of natural emulsion biological curing of the present invention agent is environmentally friendly, can not pollute.
