Its advantages are high quality and low cost.
Description
Technical field
What the present invention relates to is that a kind of low grammes per square metre vacuum is being steamed the production method of aluminizing with paper, belongs to papermaking
Technical field.
Background technology
Vacuum aluminium-plated paper with its preferably the characteristic of packing property, ornamental, economy and the low residual good environmental protection of aluminium can obtain the favor in market day by day.The method of producing vacuum aluminium-plated paper at present generally has two kinds, and a kind of is transfer aluminum plated method, and another kind is direct Alplate method.The former generally is used for the high grammes per square metre paper of aluminizing, and it is compound with paper substrate again to form aluminium foil by the aluminium ingot calendering, and the aluminium coated of production is also thicker, thereby cost is higher, simultaneously this paper of aluminizing discarded after, very difficult natural degradation easily causes environmental pollution.And the latter generally is used for aluminizing of the 100 following low grammes per square metre body paper of gram, the graininess that is directly formed aluminium by aluminium ingot under vacuum state is directly steaming on paper substrate, thereby aluminium coated is thinner, aluminium is residual very low, more adapts to environmental protection requirement, but very high to the requirement of body paper, require paper substrate to have air permeability and good, temperature tolerance, stability, especially the following vacuum of 55 gram paper are being steamed the paper of aluminizing, domesticly still can not produce, all dependence on import, cost an arm and a leg.
Summary of the invention
The objective of the invention is to deficiency at above-mentioned existence, propose a kind of low grammes per square metre vacuum and steaming the production method of aluminizing with paper, the low grammes per square metre vacuum of producing is being steamed to aluminize and is being used paper, production cost is low, paper quality is good, and import substitutes fully are after aluminizing, its paper is applicable to the packing of the demanding product of decorative effect, is specially adapted to do the liner of tobacco bale.Technical solution of the present invention:
Comprise making beating, slurry configuration, the body paper of manufacturing paper with pulp, preparation coating, coating, press polish, back segment processing technology, wherein
In the beating process, long fine freedom is controlled at 340～380ml, the short fiber freedom is controlled at 310～350ml;
In the slurry configuration technology, by long fine: short fiber: broken=18～24: 46～52: 28～32 are configured;
In the body paper technology of manufacturing paper with pulp,
Paper stock on the forming web after dehydration moulding, squeezing, leading portion drying, increase by a surface starch applying glue step, resin added 2～3g/m
2, ash is controlled at 7～10%,
The adding proportion of each additive is fluorescent brightening agent 400～1000ppm, coloring agent 10～50ppm., filler 5～8%, starch 0.6～1.2%, sizing agent 0.6～1.2%, CATION reservation auxiliary agent 100～400ppm, anion reservation auxiliary agent 1000～4000ppm;
In the preparation coating process, proportioning components is a calcium carbonate: china clay=30～35: 65～70; Starch: latex=2.5～3.5: 14～18, dispersant: defoamer=0.05～0.10: 0.05～0.10, anti-hydrated agent: lubricant=0.7～1.0: 0.7～1.0, the coating solid content is controlled at 60～65%, and viscosity Control is at 1000～500cps;
In the coating process, one side coating, coating weight is 7～8g/m
2, another side is coated with starch, and coating weight is 2～3g/m
2
In the calendaring technology, adopt the supercalendering mode of 9 nips, pressure is 160～180kN/m, and temperature is 140～160 ℃, makes 75 ° of glossiness 〉=60% of the coated face of paper.
The invention has the beneficial effects as follows: 1, filled up the blank of domestic this product, import substitutes have more far-reaching social benefit fully; 2 production costs are low, paper quality good, have favorable economic benefit.
