Abstract
The invention provides a kind of extrusion molding manufacturing method of compound decorative plastic part, this method comprises the steps: 1) select materials, select precoated metal plate that is fitted with decorative flexible materials or sheet metal for use with surface decoration effect; 2) has resistant to elevated temperatures binding agent in the coating of the back side of precoated metal plate or sheet metal; 3) with precoated metal plate or sheet metal through after cutting, carry out the flange moulding with bender; 4) the precoated metal bar or the bonding jumper of moulding are put into the extrusion die forming cavity, the hot melting plastic of extruding with extruder merges in mold cavity then, and just extrusion molding goes out to have the compound decorative plastic part of decorative effect.Speed of production of the present invention is fast, and the yield rate height is particularly useful for making the compound decorative plastic part of the bar shaped that length is long, shape of cross section is consistent.
Description
Technical field:
The present invention relates to a kind of surface decoration technique of working of plastics, the preparation method that just can finish the decorative appearance working of plastics that is applicable to household electrical appliance, household articles, building materials by expressing technique is relevant.
Background technology:
The patent No. provides compound decorative plastic part in the mould that available common injection membrane tool finishes for ZL200610020181.X.This compound decorative plastic part comprises plastic substrate, the metal level compound with plastic substrate, the decoration flexible layer compound with metal level.This method is particularly useful for making the shell of large scale product.
The production method of strip decoration mainly contains following method at present:
One, section bar co-extrusion (comprising) with co-extrusion before co-extrusion before the material and the unlike material
1. be PVC and PVC co-extrusion with the material co-extrusion.This kind extruding technology be exactly the thickness of squeezing into one deck same material at the big face of section bar be the colored top layer (mostly being the wood grain look) of 0.4-0.6mm, thereby play decoration function, this kind method deficiency is that color and surperficial texture are single, product rigidity a little less than.And the general co-extrusion face of co-extrusion section bar uses out of doors, thus its anti-old performance a little less than, time one length can cause color to shift and fade.
2. the unlike material co-extrusion is promptly squeezed into the thick colored PMMA material (or ASA material) of one deck 0.25-0.5mm on big top layer of section bar.Anti ageing property is better than PVC, but color and surperficial texture are single, and because of unlike material, grasp the control of expressing technique is difficult, the adhesive power of two kinds of materials and temperature control have directly gets in touch, and typing the time is subjected to the influence of cooling velocity, and the shrinkage factor difference of two kinds of materials can cause shape bending or later stage bending.
Two, section bar is carried out film
Section bar is carried out film and by machinery section bar carried out gluing (PUR PUR or solvent-borne type glue), and is film adhered on the section bar surface the PVC of special use then.This kind method need increase special equipment, and relative cost is higher, produces complexity of debugging.And can certain pollution be arranged to environment with solvent-borne type glue overlay film, product needs to place a period of time and just can reach adhesion strength behind overlay film, needs large-area place stack product.
Summary of the invention:
The objective of the invention is in order to provide a kind of speed of production fast, the yield rate height, it is longer to be particularly useful for length, the preparation method of the compound decorative plastic part that can finish in extruded mould of the bar shaped of shape of cross section unanimity.
The object of the present invention is achieved like this:
The extrusion molding manufacturing method of compound decorative plastic part of the present invention, this method comprises the steps:
1) selects materials, select precoated metal plate that is fitted with decorative flexible materials or sheet metal for use with surface decoration effect;
2) has resistant to elevated temperatures binding agent in the coating of the back side of precoated metal plate or sheet metal;
3) with precoated metal plate or sheet metal through after cutting, carry out flange with bender and be shaped to precoated metal bar or bonding jumper;
4) the precoated metal bar or the bonding jumper of moulding are put into the extrusion die forming cavity, the hot melting plastic of extruding with extruder merges in mold cavity then, and just extrusion molding goes out to have the compound decorative plastic part of decorative effect.
The above-mentioned sheet metal with surface decoration effect is bushing or mirror board.
The above-mentioned precoated metal plate or the thickness of sheet metal are 0.1～2mm.
Comparing preparation method of the present invention with present section bar decoration manufacture craft has the following advantages:
1) adopted metallic plate to increase the rigidity of flexible decorative layer in the decorative plastic part of the present invention, so good rigidly, the shrinkage factor difference that is difficult for producing because of two kinds of materials causes the situations of shape bending, and has decorative effect more attractive in appearance, abundanter than co-extrusion section bar.
2) the present invention is a decorative effect of having finished frosting in the process of extrusion molding simultaneously, need not the follow-up film coated decorative operation of carrying out, so it is simple to carry out membrane process than section bar, saves processing cost and equipment input cost, fast growth, yield rate height.
3) applied widely, be particularly useful for making length length, the consistent bar shaped decorative plastic part of shape of cross section, as TV machine side moulding shape decoration, the frame decoration of family expenses photo frame and the appearance ornamental pieces of plastic-steel door and window.
Description of drawings:
Fig. 1 is a TV machine side frame decorative strip structure schematic diagram.
Fig. 2 is the A-A cutaway view among Fig. 1.
Fig. 3 is a section bar ornamental strip cutaway view.
Fig. 4 is section bar ornamental strip and plastic material assembling schematic diagram.
The specific embodiment:
Embodiment 1:
Fig. 1, Fig. 2 have provided present embodiment 1 TV machine side frame decorative strip structure schematic diagram.Referring to Fig. 1, Fig. 2, TV machine side frame ornamental strip by plastic substrate 1, by adhesive layer 2 and plastic substrate compound be fitted with decorative flexible materials thickness be the overlay film cold-rolled steel sheet layer 3 of 0.8mm.
The preparation method step of present embodiment face frame television set ornamental strip is as follows:
1. select for use the thickness that is fitted with decorative flexible materials to be about 0.5mm overlay film cold-rolled steel sheet (sheet metal that also can employing itself has decorative effect, as bushing, mirror board etc.).
2. the back side on the overlay film cold-rolled steel sheet applies and has resistant to elevated temperatures adhesive layer;
3. after above-mentioned overlay film cold-rolled steel sheet process being cut, carry out two-dimentional flange moulding with bender again;
4. the overlay film cold rolled metal thin plate of two-dimentional moulding is put into the extrusion die forming cavity, the hot melting plastic of extruding with extruder merges in mold cavity then, and just extrusion molding goes out to have the TV machine side frame ornamental strip of decorative effect.
