Description
Technical field
The invention belongs to field of fine chemical, especially relate to a kind of fruit bag outer bag organosilicon paper waterproof finishing agent and method for using thereof.
Background technology
Get into 21 century, the Along with people's growth in the living standard, the continuous variation of consumption idea, pollution-free food has become a kind of fashion that people pursue, and client more and more payes attention to the inherent quality and the presentation quality of fruit when buying fruit, and is more and more fastidious.The fruit bag technique functions comes from Japan, existing so far more than 100 year history, fruit bag technology; Can the effectively preventing disease and pest, the deformity that prevents natural disaster and cause, thus improve the presentation quality of fruit; And can promote fruit color; Improve cleanliness factor, strengthen the fruit aesthetic feeling, reduce pollution by pesticides.Help producing high-grade pollution-free food.
Fruit paper bag divides inner bag paper and outer bag paper; Inner bag paper is generally band look onionskin, and impregnation process is carried out with wax in the surface, and its water repelling property obtains easily; The level of outer bag paper waterproof requirement is higher; Not only require to have good anti-wettability, but also require to have high anti-water permeability and high wet strength and good air permeability.Domestic waterproofing agent commonly used now is paraffin wax emulsions and organic silicon emulsion etc.
The waterproof effect of paraffin wax emulsions is better, but gas permeability is undesirable, and for example document " the anti-water treatment of the outer bag of fruit cap bag paper " is mentioned; Organic silicon emulsion not only waterproof effect is better, and has goodish permeability, in the past because price is high; Can not get using widely; Through our continuous exploration and research, it is suitable to make waterproof effect, the product that price is suitable.Product operation is simple, and equipment is easy to get.
Summary of the invention
The objective of the invention is to improve the deficiency of prior art and a kind of suitable fruit bag the organosilicon paper waterproof finishing agent and the method for using thereof that waterproof, waterproof and air permeable effect are good, price is suitable of paper in addition be provided.
A kind of organosilicon paper waterproof finishing agent provided by the invention; A kind of organosilicon paper waterproof finishing agent; Be characterized in that by weight portion be 2-6 part methyl hydrogen containing siloxane emulsion, 8-24 part cationic hydroxy polysiloxane emulsion; 0.1-1.5 part catalyst is formed, wherein catalyst is a kind of in zinc stearate, the zinc acetate.
In order further to realize the object of the invention, can be that described methyl hydrogen containing siloxane emulsion is a side chain property containing hydrogen silicone oil, hydrogen content 1-3%, emulsion appearance are milky white liquid, and the pH value is 4-6, and effective content is greater than 30%.
In order further to realize the object of the invention; In the time of can being described Methyl Hydrogen Polysiloxane Fluid emulsion; Be that methyl hydrogen containing siloxane and emulsifier is even, 30%, 40% gradation by final Methyl Hydrogen Polysiloxane Fluid emulsion amount added entry then, through homogenizer 1-2 hour; Use acetate or lemon acid for adjusting pH value to be 3-4; Can obtain uniform and stable emulsion, emulsifying agent is 1305,1307,1310 of isomery 13 polyethenoxy ether class, one or both among NPE, OPEO, S-60, T-60, S-80, the T-80 and above mixture.
In order further to realize the object of the invention; It can be described cationic hydroxy polysiloxane microemulsion; Be to form through the cationic emulsifier emulsion polymerisation by octamethylcy-clotetrasiloxane; Emulsion appearance is milky white colour band fluorescence liquid, and the pH value is 5-7, and the content of hydroxyl dimethyl silicone polymer and emulsifying agent is no less than 30% of quality of the emulsion.
In order further to realize the object of the invention; In the time of can being described cationic hydroxy polysiloxane emulsion, be that emulsifying agent and water are mixed, reflux state adds the 12-18 octamethylcy-clotetrasiloxane doubly of emulsifying agent weight down; Stir and heat up; Add a kind of in catalyst potassium hydroxide, potassium hydroxide, the TMAH, react 8-10 hour, add the acetic acid cancellation and react; Promptly get the translucent blue light stable microemulsion liquid that is, emulsifying agent is a kind of in dodecyl dimethyl benzyl ammonium bromide or the dodecyl benzyl dimethyl ammonium chloride.
In order further to realize the object of the invention, can be catalyst to be dissolved in water fully according to formula rate, add methyl hydrogen containing siloxane emulsion and cationic hydroxy polysiloxane microemulsion then, thin up is to effective content 1-3% then; Get maceration extract, and in 2-4 hour, finish using, get pending paper; Put into the above-mentioned maceration extract that obtains, soaked 20-30 minute, take out; Drain away the water, temperature 70-90 ℃, time 5-10 minute.
Compared with present technology the present invention has following distinguishing feature and good effect: organic silicon emulsion used herein, mainly rely on the containing hydrogen silicone oil emulsion, and the cationic hydroxy polysiloxane emulsion between react; Form one deck water-proof breathable properties diaphragm, the not only anti-wettability of this diaphragm is good, also has high anti-water permeability and high wet strength; The paraffin wax emulsions of comparing; Though the water proofing property of paraffin wax emulsions is better, its gas permeability is relatively poor, is unfavorable for the growth of fruit.The containing hydrogen silicone oil emulsion itself has certain self-crosslinking film forming; It is certain water proofing property; But the film forming insufficient strength of self; Cooperate the cationic hydroxy polysiloxane emulsion can increase into film strength, the cationic hydroxy polysiloxane emulsion is excessive in the prescription, is in order effectively to prevent containing hydrogen silicone oil emulsion self film forming.The paper of handling through these article under field conditions (factors), the waterproof term of validity can reach 8-10 month.
