Abstract
The invention discloses a production technology of a waterproof type high-bonding-strength corrugated board. The production technology comprises the steps that multiple layers of corrugated paper are bonded into the corrugated board, and the surfaces of the corrugated board is coated with waterproof paint, wherein starch glue used for bonding the multiple layers of corrugated paper is formed by mixing starch, water-soluble polymers and a cross-linking agent, and the waterproof paint is superamphiphobic interface paint. Due to the adoption of high-waterproof starch glue and the superamphiphobic interface paint, corrugated cases with the excellent waterproof performance and high strength can be produced, waxed cartons and polyethylene pressed film cartons can be recycled, the use effect is good, and economic benefits and social benefits are remarkable.
Description
Technical field
The present invention relates to corrugated board production technique.
Background technology
Along with the development of corrugated case packaging market, increasing to waterproof corrugated case demand.The water proofing property of common corrugated case and moisture resistance are all poor, can not meet waterproofing packing.And current current waterproof and moistureproof corrugated case, as waxing carton and polyethylene press mold carton, all cannot recycling.
Summary of the invention
Technical problem to be solved by this invention is just to provide the high bonding strength corrugated board production of a kind of water proof type technique, makes corrugated case have good water resistance, has again higher-strength and is convenient to recycling.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: the high bonding strength corrugated board production of a kind of water proof type technique, comprise that corrugated multilayer is bonded as corrugated board and on corrugated board surface, applies the step of water-repellent paint, the amylan of the bonding use of described corrugated multilayer is mixed by starch, water-soluble polymer, crosslinking agent, and described water-repellent paint adopts super two thin interface coatings.
Preferably, described water-soluble polymer is by acrylamide, sodium acrylate and chlorination octadecyl dimethyl-allyl-ammonium copolymerization.
Preferably, described crosslinking agent is mixed and is formed by benzophenone, trimethyol propane triacrylate.
Preferably, the mass ratio between each component of described amylan is starch: water-soluble polymer: crosslinking agent=90-98: 10-2: 0.2-0.5.
Preferably, the mass ratio between each component of described amylan is starch: water-soluble polymer: crosslinking agent=94-96: 5.8-3.7: 0.5-0.3.
The present invention is by adopting high waterproof amylan and ultra-amphosphobic interface coating, can produce and there is good water resistance and high-strength corrugated case product, avoided waxing carton and the polyethylene press mold carton cannot recycling, result of use be very good, and economic benefit and social benefit are remarkable.
The specific embodiment
Below in conjunction with specific embodiment, the present invention is made and being illustrated.
In the present embodiment, the high bonding strength corrugated board production of water proof type technique comprises that corrugated multilayer is bonded as corrugated board and on corrugated board surface, applies the step of water-repellent paint, the amylan of the bonding use of described corrugated multilayer is mixed by starch, water-soluble polymer, crosslinking agent, and described water-repellent paint adopts super two thin interface coatings.Described water-soluble polymer is by acrylamide, sodium acrylate and chlorination octadecyl dimethyl-allyl-ammonium copolymerization.Described crosslinking agent is mixed and is formed by benzophenone, trimethyol propane triacrylate.Mass ratio between each component of described amylan is starch: the mass ratio between water-soluble polymer: crosslinking agent=90-98: 10-2: 0.2-0.5 or each component of described amylan is starch: water-soluble polymer: crosslinking agent=94-96: 5.8-3.7: 0.5-0.3.
Amylan through modification is suspended in the pastel being comprised of water and carrier equably, due to carrier function, its solution is incorporated in the porous and water imbibition surface of fluting medium, polyhydroxylated polymer is gel under the effect of temperature and carrier, after dry, become film strength larger, thereby improve the bonding intensity of corrugated board.
" the high bonding strength corrugated board of water proof type " product that production technology of the present invention is produced is not to obtain water resistance by waxing or polyethylene press mold, but by technological innovation, makes corrugated board self have good water resistance.
As everyone knows, corrugated board is to be bonded by fluting medium, and the most frequently used adhesive is starch adhesive.Starch is the high polymer of glucose, and the polysaccharide structures of solubility, lower without the common starch adhesive bonds fastness of modification, meets after water, and adhesive property is poorer, so low by sticky corrugated board (case) intensity of producing of common starch adhesive, water resistance is poor.Making " the high bonding strength corrugated board of water proof type " main key technology is the modification of starch adhesive.
By number of ways, carried out the development work of modified starch adhesive, wherein useful alum, keto-aldehyde tree refers to, amine, clorox, odium stearate, sodium hydrogensulfite etc. carry out modification to starch, has obtained good effect.But the problems such as these methods exist respectively adhesive-preparing technology complexity, raw material sources difficulty, so we have abandoned above-mentioned technology path.Then scientific research personnel adopts the mixing formula innovation of starch-water-soluble polymer-self-crosslinking, and coating and glue-applying technique aspect have been obtained to technological break-through, has finally obtained good result, has produced high-quality " the high bonding strength corrugated board of water proof type ".
By the mixing formula of starch-water-soluble polymer-self-crosslinking, obtain high waterproof and grease proofing modified starch adhesive, adopt water-soluble polymer HAWP18 by acrylamide, sodium acrylate and chlorination octadecyl dimethyl-allyl-ammonium (MJ18) copolymerization as the effective modifier of this project.This water-soluble polymer can be water-soluble together with starch, forms mixed glue, and adding before use benzophenone (BP) is that photosensitizer, trimethyol propane triacrylate (TMPTA) are crosslinking agent; After this mixed glue drying and forming-film, there is self-crosslinking, form netted structural adhesive layer with paper fiber, be difficult to by water and oil molten Jie again, make bonding strength increase substantially simultaneously, and can not go mouldy, hydrophobicity and oleophobic property are strong, thereby have effectively improved intensity, waterproof and the oil preventing performance of corrugated board (case).The innovation of amylan formula has prevented the infiltration of water to cardboard (case) itself from corrugated board (case) immanent structure, has improved corrugated board (case) water resistance.This is first yuan of waterproof system of the present invention.Second yuan of waterproof system of the present invention is at the novel super thin property interface coating of corrugated board (case) surface coating.Employing catalyzes and synthesizes the fluorine-containing POSS obtaining, and has branched structure, and the fluorine-containing density in space is high, and surface can be low, and hydrophobic effect is good, the feature that heat-resistant stability is high.This coating utilization from down to up, by atom, to molecule, epitaxial growth chemical method by molecule to aggregation, made, can be built (adding protruding and recessed identical) interfacial structure of ultra-fine micron sized geometry complementation on specific surface.Because the surface at this ultra-fine micron-scale indentation can make adsorption gas molecule stable existence, so be equivalent to the gas membrane that has one deck stable in macro surface, water cannot directly be contacted with the surface of material, thereby the surface that makes material presents extraordinary hydrophobicity, reach effective waterproof object.
