Description
Technical field
The present invention relates to packing case technical field, be specifically related to the production technology preparing waterproof heat-insulation composite board.
Background technology
Along with people's living standard improves constantly, also more and more pay attention to material requirements quality, for improving fruit and vegetable food, meat products, frozen product long-time storage quality, wrapping enterprise and logistics system develop foamed heat insulating case.Foamed heat insulating case has the product of insulation demand for transporting, greatly improve the holding time of product, is applicable to long distance transportation.Now used on the market insulation packing case is shaped for EPS foaming mould, there is following problem:
EPS foaming mould is shaped, and case can only be become to transport, and due to cost of transportation problem, the limited market coverage of packing case haul distance is little; Become case transport, due to cost of transportation problem, very difficult realization is reused, and causes significant wastage to resource; Expanded material intensity is lower, repeatedly carries fragile; The toxicity that expanded material itself has and product directly contact and easily cause into product (food) secondary pollution; The low not easily natural degradation of the EPS expanded material rate of recovery, causes white pollution.
Summary of the invention
For above-mentioned prior art, the object of the present invention is to provide a kind of production technology preparing waterproof heat-insulation composite board
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:
Prepare a production technology for waterproof heat-insulation composite board, it is characterized in that, comprise the following steps:
1. get out the expanded material reclaiming paper fiber, and to the moisture content of 20%-25%, fully mix recovery paper fiber humidification thoroughly form slurry with adhesive, lubricant, blowing agent; The component of described slurry is paper fiber 80-90 part, adhesive 5-30 part, catalyst 0.01-0.1 part, lubricant 0.05-0.5 part, blowing agent 1-2 part;
2. continuous extrusion apparatus is used to be injected in honeycomb hole in paper honeycomb stretching composite log by slurry;
3. carry out microwave catalysis foaming in honeycomb pressing bringing-up section, form honeycomb and be incubated plywood again.
In the present invention, described adhesive be amylan or melamine any one.
Catalyst is borax, magnesia, lubricant be stearic acid, calcium stearate, modified fat acid, end molecule PE cured in any one.
Blowing agent is any one in AC blowing agent, sodium bicarbonate, carbon ammonium, urea, low molecule oleic acid.
Compared with prior art, the present invention has following beneficial effect:
Waterproof heat-insulation composite board provided by the invention its there is following characteristics: flat Compressive Strength≤1000Pa, limit pressure degree≤1200N/M, expose strong degree≤12J, pass heat be number≤0.5W/m
2.k, Xi Shui≤5g/m

Detailed description of the invention
Below in conjunction with the drawings and the specific embodiments, the invention will be further described.
The manufacturing process of water-fast heat-insulating carton is: by improving paper honeycomb production technology, at honeycomb hole filled with foaming material inside, use leaching membrane paper as facial tissue, aluminium platinum brown paper is thermal radiation resistant layer, described filling-foam main material is for reclaiming paper fiber, fully mix form slurry thoroughly by reclaiming the moisture content of paper fiber humidification to 20%-25% with adhesive, lubricant, blowing agent, slurry is injected in honeycomb hole in paper honeycomb stretching composite log by use continuous extrusion apparatus.Carry out microwave catalysis foaming in honeycomb pressing bringing-up section, form honeycomb and be incubated plywood again.
Described filling-foam main material is for reclaiming paper fiber, and proportioning is paper fiber 80-90 part, adhesive 5-30 part, catalyst 0.01-0.1 part, lubricant 0.05-0.5 part, blowing agent 1-2 part.Adhesive be amylan or melamine any one, catalyst is borax, magnesia, lubricant be stearic acid, calcium stearate, modified fat acid, end molecule PE cured in any one, any one in blowing agent AC, sodium bicarbonate, carbon ammonium, urea, low molecule oleic acid.Honeycomb is incubated plywood core paper again and uses corrugated paper, and facial tissue adopts film brown paper, inner paper to use aluminium foil brown paper, has good insulating water-proof ability after sheet material forming.Carton designs provided by the invention can design by GB, aft-loaded airfoil and corrugated case production technology one to, efficiency height can realize equipment and share.
Described honeycomb waterproof heat-insulation composite board by outer and in successively by aluminium foil brown paper, foaming cellular sandwich with film brown paper trilaminate material is composite adhered forms.Described foaming cellular sandwich comprises foaming and fills layer and paper honeycomb core, and described foaming is filled layer and is positioned at paper honeycomb core top layer; The thickness that layer is filled in foaming is 2mm ~ 5mm, and the thickness of paper honeycomb core is 4mm ~ 10mm.The collapsible water-fast heat-insulating carton be made up of honeycomb waterproof heat-insulation composite board based on honeycomb composite insulation boards inside and outside film brown paper and aluminium foil brown paper be set respectively make it have effect that is water-fast, insulation.The collapsible water-fast heat-insulating carton be made up of honeycomb waterproof heat-insulation composite board has with characteristic: flat Compressive Strength≤1000Pa; Limit pressure Du≤1200N/M; Expose Qiang Du≤12J; The hot Xi Shuo≤0.5W/m of Chuan
2.k; Xi Shui≤5g/m
