Description
Technical field
The present invention relates to a kind of edge band and preparation method thereof, be specifically related to a kind of acrylic edge bar and preparation method thereof, belong to edge band technical field.
Background technology
When carpenter's dress is drilled, the periphery for window frame edge, furniture or plank decorative panel is received limit and is generally adopted the edge band of thinner strip overlap joint to fill up, to drill the last round-off work of construction as carpenter's dress.Edge band is one of accessory commonly used in furniture decoration; be used for carrying out sealing to the section of Furniture panel; thus protection sheet material is from the adverse effect of Environmental Water, illumination etc., and the formaldehyde of sheet material inside can be stoped to volatilize, effect decoration can also played and beautify.
The main facing edging material of furniture comprises: melamine impregnated paper, PLASTIC LAMINATED (HPL), paint, wooden skin, acrylic (PMMA), PVC edge band, PP edge band etc.
Acrylic (acrylic) be also PMMA or polymethyl methacrylate, chemical name is polymethyl methacrylate, be commonly called as lucite, it is a kind of exploitation important thermoplastic comparatively early, there is the good transparency, chemical stability and weatherability, easy dyeing, easily process, attractive appearance, has a wide range of applications in building industry.
Acrylic has lot of advantages: 1. splendid transparency, 2. excellent weatherability, and 3. processing characteristics is good, be easy to shaping, 4. excellent combination property, 5. nontoxic, even if also harmless with people's Long Term Contact, the gas produced during burning is also had not produce toxic gas, 6. light weight, inexpensive.Acrylic edge bar, due to its attractive in appearance, durable, wear-resisting, scratch resistant feature, is widely used as the first-selection of the edge band of top-grade furniture.
Acrylic board divides moulding plate and stripper plate by production technology, the technique such as moulding process can adopt casting, injection moulding, extrudes, thermoforming.
Cast molding is used for the section bars such as shaping methacrylate sheet, bar, namely uses bulk polymerization profiles.Cast molding is relatively applicable to machining large-sized mark board, and in softening process, the time is slightly long relatively, and the goods after moulding by casting need to carry out post processing, and post-treatment condition is incubated 2h at 60 DEG C, is incubated 2h at 120 DEG C.
Injection mo(u)lding adopts the particulate material obtained by suspension polymerisation, is molded on common plunger type or screw injection molding machine and carries out.Injection-molded item also needs post processing to eliminate internal stress, processes and carries out in 70-80 DEG C of hot air circulation drying oven, and the process acrylic rod time looks products thickness, generally all needs about 4h.
The particulate material that extrusion molding suspension polymerisation is produced prepares methacrylate sheet, bar, tubing, sheet material etc., but the section bar of preparation like this, mechanical property, heat resistance, solvent resistance are all not as good as the section bar of moulding by casting, its advantage is conducive to bending and thermoforming processing, the softening time is shorter, and production efficiency is high.
Thermoforming is process methacrylate sheet or sheet material being made various sizes shaped products, require that the blank clamping of size is on mold frame by cutting into, heating makes it soften, pressurization makes it be adjacent to die face again, obtain the shape identical with profile, after cooling and shaping, namely finished edge obtains goods.
At present, conventional plastic household edge band is surface printing, then is protected by printed layers coating UV layer, its printing-ink poor adhesive force, easy delamination.The making of acrylic edge bar mostly adopts and acrylic edge strip material is heated to molten condition, is then extruded the acrylic edge bar of required shape and size by extrusion shaping machine, then cools rolling.
This area needs a kind of operation of exploitation easier, the preparation method of the acrylic edge bar that heating-up temperature is lower.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, a kind of acrylic edge bar and preparation method thereof is provided.The adhesive force of acrylic edge bar pattern of the present invention is high, difficult drop-off.
For reaching this object, the present invention by the following technical solutions:
An object of the present invention is to provide a kind of acrylic edge bar, and the pattern setting of described acrylic edge bar is in the back side of edge band.
" back side " of described edge band refers to and the one side that Furniture panel bonds.By the back side of pattern setting in acrylic edge bar, pattern can be avoided to contact with hot pressing external force, effectively solve the problem that comes off of the pattern when hot-pressing, edge-sealing bar carries out edge sealing.
Two of object of the present invention is to provide a kind of preparation method of acrylic edge bar, comprises the steps:
(1) acrylic material grain is dried;
(2) the acrylic material grain after oven dry is extruded to obtain transparent base;
(3) in the substrate backside printed patterns that step (2) obtains;
(4) be coated with polyurethane aqueous glue-line at printed patterns place, dry to obtain finished product.
Preferably, described protective layer is polyurethane aqueous glue-line.
Aqueous polyurethane is using water as medium, and polyisocyanates and polyethers or PEPA, utilize-OH the radical reaction in polyisocyanates in-CNO base and alcohol to generate base polyurethane prepolymer for use as, after chain extension, become the urethanes of anion with blocking agent.
Acrylic transparent base of the present invention extrudes acquisition by acrylic material grain.
Technological parameter the present invention that acrylic material grain of the present invention extrudes acrylic transparent base is not particularly limited, and those skilled in the art can select according to actual conditions.
Typical but non-limitingly extrude technological parameter in blocks and be: screw compression than 2,150-180 DEG C, barrel temperature rear portion, middle part 170-200 DEG C, anterior 170-230 DEG C, extrusion pressure 2.8-12.4MPa, inlet temperature 50-80 DEG C, die temperature 180-200 DEG C.
The object that acrylic material grain of the present invention first carries out drying before extrusion is away the moisture in acrylic material grain, avoids producing bubble in extrusion, affects the adhesive force of outward appearance and pattern.
Preferably, described bake out temperature is 85 ~ 95 DEG C, such as 86 DEG C, 87 DEG C, 88.6 DEG C, 89.5 DEG C, 92 DEG C, 93.1 DEG C, 94.6 DEG C etc., preferably 88 ~ 92 DEG C, preferably 90 DEG C further.
Bake out temperature is too high, and acrylic material grain easily softens, and is unfavorable for the shaping of extrusion profile; Bake out temperature is too low, and moisture not easily removes, and causes edge band outward appearance poor, pattern poor adhesive force.
Preferably, described drying time is 160 ~ 200min, such as 162min, 164min, 167min, 169min, 175min, 178min, 183min, 187min, 193min, 196min etc., preferably 170 ~ 190min, further preferred 180min.
Drying time is long, and easily cause acrylic deliquescing, drying time is too short, and moisture removal is not thorough, affects edge band outward appearance and pattern adhesive force.
Preferably, the technological parameter extruded described in step (2) is: Single screw extrusion, barrel temperature 180 DEG C ~ 200 DEG C, sizing head temperature 200 DEG C ~ 220 DEG C, bosh temperature 15 DEG C ~ 18 DEG C.
As optimal technical scheme, a kind of described method of preparation of acrylic edge bar comprises the steps:
(1) acrylic material grain is dried 160 ~ 200min at 85 ~ 95 DEG C;
(2) the acrylic material grain Single screw extrusion after oven dry is obtained transparent base, the barrel temperature of Single screw extrusion 180 DEG C ~ 200 DEG C, sizing head temperature 200 DEG C ~ 220 DEG C, bosh temperature 15 DEG C ~ 18 DEG C;
(3) in the substrate backside printed patterns that step (2) obtains;
(4) be coated with polyurethane aqueous glue-line at printed patterns place, dry to obtain finished product.
Compared with prior art, the present invention has following beneficial effect:
Pattern setting on edge band is being treated and one side that edge sealing furniture bonds, and is covering protective layer, can effectively avoid edge band pattern to come off in edge sealing process.
