Description
Technical field
The invention belongs to latex product manufacture field, particularly 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.
Background technology
Rubber is a kind of important industrial raw material, is known as four large industrial raw material with iron and steel, oil, coal.Rubber is owing to having distinctive snappiness and good physical and mechanical properties and electrical insulation capability, and purposes is very extensive.Therefore the consumption of rubber is very large.Conventionally rubber used comprises natural rubber and synthetic rubber.Current global demand year reaches 2,000 ten thousand tons, wherein 1,200 ten thousand tons of asynthetic rubbers, 8,000,000 tons of natural rubbers.But asynthetic rubber cannot replace natural rubber.7% of the natural rubber output Zhi Zhan world of China, and demand accounts for the more than 22% of the world.
The liquid that natural emulsion (also claiming caoutchouc latex) flows out while being rubber tree 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 making 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, to make it solidify out into elastic solid material---natural rubber to adding a certain proportion of acid reagent can produce crosslinking reaction in natural emulsion, thisly can make material that latex solidifies rapidly in peptizer, also referred to as solidifying agent.
Curing most of formic acid that adopts of natural latex rubber in the world today, formic acid is not only toxic, severe contamination the overall situation of human survival, and natural rubber milk-quality is declined, color blackening.Formic acid, always as the solid technologic necessary raw material of natural rubber curdling, is mainly because formic acid can neutralize the alkalescence of the ammoniacal liquor (preservatives) adding early stage for a long time, reduces the set time of natural rubber breast simultaneously.But formic acid nonideal natural emulsion solidifying agent.
So, on market, need a kind of adopt biological products be main acidic substance, nontoxic to human body and environmental safety, can ensure solidifying agent natural rubber products quality, easy to use.
Summary of the invention
The object of the present invention is to provide a kind of solidifying agent, in the raw material of described solidifying agent, contain that amino naphthalenes disulfonic acid, citric acid, bisulfite are received, carbamate, Sorbic Acid.

B. described natural emulsion biological curing agent is added in the natural emulsion of 900-1000 weight part, fully stir, obtain curing 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 latex quick solidifying, and rubber quality improves, 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 generating in latex, growth that can also anti-bacteria 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 conventional food preservatives, the effect that has antiseptic to turn sour, extend the shelf life;
Described amino naphthalenes disulfonic acid, these two kinds of materials of carbamate play good solidification in weakly alkaline material, and natural rubber latex is 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.
Various raw materials synergy above, for caoutchouc latex curing played good effect.
The present invention compared with the prior art tool has the following advantages:
1, in natural emulsion biological curing of the present invention agent, do not contain ammonia, nonirritant, healthy nontoxic, human body is had no side effect.
