Abstract
The invention relates to an oxidized polyethylene wax emulsion water-repellent agent which is prepared from the following raw materials by weight: 35-40% of oxidized polyethylene wax, 3-5% of compound mixed emulsifying agent of Tween-60, Span-80 and disproportionated rosin, 0.2-0.4% of silicon dioxide nano powder and the balance of water. The water-repellent agent has pH of 7-8 and viscosity of 150-450 mP*s. The emulsion is modified by nano silicon dioxide, so that the blend-modified emulsion stably exists in the form of adsorbing gas atom on nano-sized concave surface, and is equivalent to a layer of stable gas film on macroscopic surface, and oil or water cannot directly contact the surface of the material, therefore, the material surface presents hydrophobicity and oleophobicity, and obtains super-hydrophobic super-oleophobic effects. The product also has certain fire retardancy, and can meet waterproof and moistureproof functions as well as combustion-supporting performance of carton and pasteboard high-grade paper products.
Description
Technical field
The present invention relates to a kind of carton flame-proof damp-proof technology, particularly a kind of OPE emulsion water repellent agent.The invention still further relates to a kind of preparation method of this water repellent agent.
Background technology
1930's end it is found that in the paper stock fiber, to add some water miscible synthetic resin and can improve wet strength and WATER RESISTANCE significantly after the drying together, so the application of wet strengthening resin water repellent agent is got up with regard to fast development to the forties.Common this resin must can be in water high degree of dispersion, i.e. possess hydrophilic property, and have reactivity and have the electric charge opposite, i.e. cationic with fiber.These character not only impel resin adsorption on fiber, and can be effectively fixing, thereby improve the WATER RESISTANCE of paper.
Water repellent agent at present commonly used comprises that mainly fourth classifies by filmogen, can be divided into inorganic and organic two big types of water repellent agent kinds:
(1) inorganic adhesive class water repellent agent.Usually use waterglass, the anti-water mechanism that mainly bonds is that waterglass is realized condensation cure through carbonization and fixed two processes of dehydration crystallization in air, and along with the carrying out of carburizing reagent, silica gel content increases, and then free moisture evaporation and silica gel are dehydrated into solid SiO
2And setting and harden.Because CO in the air
2Concentration is low, so very slowly, there are self shortcomings such as volume contraction, intensity be low simultaneously in whole condensation cure process, the deficiency of alkali resistance and poor water resistance has also seriously limited the service condition of waterglass.
(2) organic resin sill water repellent agent.Lauxite (UF), melamine resin (MF) are in the existing very long history of application in papermaking industry.The technical indicator of Inst. of Chemical Industry, Jinan City's product has reached the level of external like product, occupies leading domestic.In addition, the seventies in 20th century, big quantity research has been made in the modification of melamine resin abroad; The trimerization of having developed high solid, stable storage is as the amine formaldehyde resin, and this resinoid has reached satisfied effect in the formulation for coating material of starch one latex mixed glue, even but the melmac of modification; In production, storage, use, still can produce a large amount of formaldehyde gases, volatile solvent or cracking micromolecule are arranged; Health is caused serious harm, can occur inflammable, contaminated air; To the unfriendly and big limitations of surrounding environment the scope of its use, therefore be tending towards superseded gradually.Bozhou, Anhui Gu Jing packaging material Co., Ltd produces beer case packaging product water repellent agent; According to requirement of client; Will oil at the glazing of special use equipment or multiple film device of beer case facial tissue after the printing carries out anti-water treatment, is divided into oiliness (solvent-borne type) and water-soluble two kinds, but pernicious gases such as a large amount of organic solvents that volatilize because of solvent-borne type; Be unfavorable for that the worker is healthy, most enterprises all adopt water-soluble glazing agent to carry out WATER REPELLENT TREATMENT at present.The said firm produces fluting medium and the special-purpose anti-aquatic products of boxboard use the applying glue body paper or spraying use on boxboard according to customer requirement; And interpolation has the binder of water-proof function; Have excellent adhesion performance and water resistance; But use cardboard after this anti-oil processing waterborne in water, to soak fully three kinds of body paper are peeled off fully, be unfavorable for enhancing productivity.
Summary of the invention
The technical problem that the present invention will solve is the deficiency to prior art, has proposed a kind of high-efficiency environment friendly, and pernicious gas volatilizations such as solvent-free, formaldehyde reduce environment-friendly type OPE emulsion water repellent agent of whole cost and preparation method thereof simultaneously.
The technical problem that the present invention will solve realizes that through following technical scheme a kind of OPE emulsion water repellent agent is characterized in:
This water repellent agent is prepared from following materials of weight proportions:
Oxidic polyethylene wax content 35%～40%,
Tween-60, Span-80, the composite mixing and emulsifying agent content 3%～5% of disproportionated rosin,
Silicon dioxide nano powder content 0.2%～0.4%,
All the other are water,
The weight proportion of Tween-60, Span-80, disproportionated rosin is 4.8 ~ 5.2:2.8 ~ 3.1:1.7 ~ 2.4 in the wherein composite blended emulsifier,
This water repellent agent pH=7～8, viscosity are 150mPs～450mPs.
A kind of preparation method of this water repellent agent is characterized in: in container, at first add OPE as main raw material, add entry, composite blended emulsifier, nano-powder material then after; Be rapidly heated 130 ℃; After treating that OPE fully dissolves, stir constant temperature emulsification 40 min under 80 ~ 85 ℃ of temperature with the 600-700r/min rotating speed; Behind NaOH adjusting pH to 7～8, discharging.
Because the oxidation modification Tissuemat E is the product that reoxidizes behind the polyethylene Pintsch process; Be mainly the long-chain saturated hydrocarbons and constitute, therefore be difficult for emulsification, the present invention selects phase transition method and the method that adopts composite nonionic emulsifier; Optimize parameters such as pH value in the emulsion process, solution temperature, emulsifying temperature, mixing speed, emulsification times simultaneously; Consider and contain small number of carboxylic acid groups and hydroxyl polar group in the chain, with NaOH regulator solution pH to alkalescent, to increase its degree of ionization; Increase stability of emulsion, finally prepare tiny, the uniform and stable emulsifying wax emulsion of particle.In the preparation process, added nanometer titanium dioxide silicon additive emulsion has been carried out modification with two thin functions; Make emulsion behind the blending and modifying at the surface adsorption gas atom stable existence of nano-scale indentation; On macro surface, be equivalent to the gas membrane that has one deck stable, oil or water all can't be directly contacted with the surface of material, thereby demonstrate pair thin property on the surface of material; Paper products, film etc. will obtain super-hydrophobic, ultra oleophobic effects after two thin boundary material technical finesses.This product has pollution-free, high-efficiency environment friendly, the volatilization of pernicious gases such as solvent-free, formaldehyde; Water-based is not burnt; Manufacturing technique is simple, and emulsion can impose on the surface through spraying, brushing, roller coat, impregnating method; Emulsion has certain fire resistance on chemical composition simultaneously, can satisfy the waterproof and dampproof function and the combustion-supporting performance of carton, cardboard fine paper goods.
