Description
Technical field
The present invention relates to a kind of metal decorative material and processing method, especially a kind of metal composite decoration panel and processing method can be widely used in decorating industries such as decoration, furniture.
Background technology
Along with decorate to decorate under the flourish trend of industry rise and furniture, the superior trend of office accommodation in the whole nation, people are to the more superior and practicability of ornament materials requirement, and then have further promoted the development and application of all kinds of new materials.Common decorative is to be formed through hot pressing is bonding by substrate and facing paper; Yet increasing people favor has the decoration of metal-like, but sheet metal when being used to decorate cost very high, and its quality is very heavy; Construction has inconvenience; To such present situation, composite decorating boards such as composited aluminum and plastic decking, iron plastic clad plate have appearred, and they are synthetic by surface layer and the hot pressing of underlying metal plate holder one deck plastic layer.But two faces of existing composite metal plate are the plane, and the difference of all kinds of composite metal plates only is that the printing effect of composite surface is different.Yet owing to be to print in the plane, the appearance that is obtained is limited eventually, can't avoid the stiff defective in plane, thereby the class of product is not high.
Summary of the invention
Technical problem to be solved by this invention is the deficiency that overcomes the above-mentioned background technology; The improvement of a kind of metal composite decoration panel and processing method is provided, the panel that is obtained should have stereoscopic texture strong, have embossment visual effect, good product quality, characteristics that product cost is lower.
Technical scheme provided by the invention is: cameo plastic-aluminum composite decorated panel; The polyethylene core that comprises aluminum soleplate, panel and middle one deck; Also accompany one deck adhesive film between described panel and the polyethylene central layer and between polyethylene central layer and the base plate respectively; Described panel is that thickness is the aluminium flake of 0.03-0.3 millimeter, is shaped on ridge design on the panel.
The degree of depth of the recess in the ridge design on the described panel is the 0.01-0.3 millimeter.
Described adhesive film is the polyethylene film that positive and negative two faces scribble polyethylenes resin bonding material, and the thickness of adhesive film is the 0.05-0.15 millimeter, and polyethylenes resin bonding material accounts for more than 60% of whole adhesive film thickness.
The raw material weight proportioning of described polyethylenes resin bonding material is: urea 40-50 part, formaldehyde (37%) 70-78 part, polyvinyl alcohol 1788#1-1.3 part, polyvinyl alcohol 1799#0.6-1.0 part, sorbierite 2-3 part, pure water 10-15 part, melamine 10-15 part, NaOH 2-2.5 part, formic acid 2-3 part.
The raw material of described polyethylenes resin bonding material also can comprise an amount of curing agent CT12, water base adhesive BM3358, water base adhesive BM3558, hydroxyethylcellulose.
The processing method of cameo plastic-aluminum composite decorated panel is following:
One, system polyethylenes resin molding
A, synthesizing polyethylene hydrocarbon resin bonding material
Elder generation transfers to PH to 8-8.5 with formaldehyde with NaOH, adds melamine, urea and polyvinyl alcohol 1799# and is warming up to 78-82 ℃ and constant temperature 0.8-1 hour, uses formic acid to transfer PH to be 5.2-5.6 then, continues to react 0.8-1 hour down at 78-82 ℃; Reactant liquor is added in the 32-36 ℃ of pure water, add sorbierite again when being white in color, polyvinyl alcohol 1788# is dissolved into the 28-32% aqueous solution, transfer PH to 7-8 with NaOH, and reaction 0.4-0.6 hour, cool to subsequent use below 40 ℃;
Getting 1 part of above-mentioned solution adds 2-3 part curing agent CT12 and fully mixes formation polyethylenes resin bonding material with 5 parts of water base adhesive BM3358,3 parts of water base adhesive BM3558,0.5 part of hydroxyethylcellulose;
B, film
Adopt two layers or three-layer co-extruded inflation film manufacturing machine, aforementioned polyethylenes resin bonding material evenly is coated in the tow sides of film, process adhesive film;
Two, product is compound
C, just multiple
Bonding with the polyethylenes resin molding respectively on aforesaid base plate, panel on the compounding machine, combined temp 80-160 ℃, and cut into required specification;
D, inferior multiple
There are base plate, panel and the polyethylene central layer of polyethylenes resin molding to be superimposed together aforementioned adhesion, on compounding machine, are bonded as one, combined temp 250-400 ℃;
E, embossing
With aforementioned compound be sheet material embossing on single drylight presses of one, the template on these single drylight presses is a concavo-convex template of single face, 100-150 ℃ of embossing temperature, pressure 20-30MPA, 15 seconds to 30 seconds time.
During synthesizing polyethylene hydrocarbon resin bonding material, also can add an amount of curing agent CT12, water base adhesive BM3358, water base adhesive BM3558, hydroxyethylcellulose.
Polyethylenes resin bonding material in the adhesive film among the present invention can repeatedly melt and moulding; Absorbing heat with aluminum deck and with the hot compound tense of PE (polyethylene) central layer and when rising to certain temperature, melting; Polyethylenes resin bonding material after the thawing is coated in the aluminum deck surface equably; Gummed power that it is superpower and cohesive force make product compound firmly, have guaranteed the stable of product quality.Because the bonding of composited aluminum and plastic decking is by the oxide-film interaction on polar substances one aluminium and aluminum metal surface, between metal surface and polymer interface, forms ionic bond; PE is bonding with apolar substance; Contain the polyethylene of shuttle base stage property group grafting and contain shuttle base ethylene copolymer; Act on the metal surface, bonding through the chemical reaction generation of Suo Ji and metal surface, bonding better through facts have proved this kind material and metal with the bonding combination property of PE.Have higher temperature during this kind polyethylenes resin co-extrusion, guaranteed the compound tense high temperature requirement; Coating is even when bonding, bonding strength is high and the characteristics of constant product quality thereby make.
Cameo plastic-aluminum composite decorated panel provided by the present invention, the decoration ridge design of its panel surface is through single drylight presses once back embossment moulding of of short duration hot pressing under HTHP.Adhesive film plays perception effect and is stretched and typing by calendering again with the pattern of panel according to template under HTHP; Form the well-bedded various ridge design of panel surface, PE central layer in the cameo plastic-aluminum composite decorated panel and base plate are not influenced by template then; And recombination time is short, only needs 15 seconds to 30 seconds; Production efficiency greatly improves.
Product provided by the invention has lightly, good planeness, good product quality (good, shock-resistant, the surperficial anti-pollution burn into of bending strength acid resistance, alkali resistance, oil resistivity, solvent resistance, scrubbing property >=10000 time), panel surface have ridge design, stereoscopic texture is strong, have the embossment visual effect; Product specification is high; Product cost is also lower; And good processability; Can be processed into various special-shaped facades and geometry through modes such as cutting, fluting, roll bending, connections, be used widely on building and the engineering at home.
