Description
Technical field
The present invention relates to a kind of plastic material and production technique, especially a kind of non-painted automobile spoiler and production technique with metalluster.
Background technology
In the painting dressing automobiles, the color of finish paint (color) can be divided into two big types: true qualities (solid colors) and metallic color (metallic colors).True qualities can be divided into Chromatic color (meaning the color that has color such as red, yellow, blue, green) and Achromatic color (meaning not colored colors such as white, grey, black) again by its color.Metallic color also can be subdivided into flash metal luster look and pearly-lustre look, and the tendency of Chromatic colorization.During the nearly last ten years; Automobile finish is coated with reload request high-decorationization (high clarity, high brightness, high flash colorize); Use the automobile of flash metal luster look and pearly-lustre look finish paint to increase year by year, in car coating, surpassed for 50% (car of the country that has and producer's matel coated flash of light look surpasses 70%).The price of matel coated flash of light look finish paint automobile is wanted expensive several thousand yuan than true qualities at home; But still develop very soon; Popularization and application is to the application of minicar, mini-bus, motor bus vehicle body; Heavy automobile cab adopts flash metal luster look finish paint also to occupy certain ratio (like " liberation " of a vapour Qingdao automobile factory, " steyr " of Ji vapour).The application of flash metal luster look originates in later stage the 1950's, is base-material with Nitrocellulose varnish, and to the mid-1960s, the Application and Development of thermosetting acrylic resin makes the application of flash of light look be able to further develop.At that time coating process is identical with the true qualities finish paint, is one to be coated with one and to dry by the fire (1C1B) technology, and film performances such as its outward appearance, weathering resistance, acid resistance, alkali resistance are low; Just produce the disadvantage of the deterioration of filming in a short time.Get into the seventies after all approach improve weathering resistance, scuff resistance and the decorative appearance of filming, just form two be coated with one dry by the fire (2C1B) finish paint Lacquer finish coating process, promptly now background color layer adds the finish paint coating process of Lacquer finish.For adapting to the needs of environmental regulation, American-European newly-built paint line has all adopted the finish paint system of environment-friendly type since the nineties, and promptly the water-based base coat adds the coating varnish (like powder clear coatings, high-solid level varnish or water varnish etc.) of environment-friendly type.
The metallize polychromatic finish need be used custom-designed air gun, and the air gun of using with spraying true qualities finish paint compares, and the paint output is many, and air pressure is high, and injection is large-minded.With strong air pressure aluminium powder is knocked attached on the application surface at a high speed, and the aluminium powder oriented parallel is arranged, a large amount of air volatilizees the solvent in the coating at short notice, the flowing of aluminium powder that is being coated with is prevented from as quick as thought, but the air gun spray efficiency is low.For improving coating efficiency; In recent years the coating process that the electrostatic spraying metal flash paint occurs; When adopting electrostatic spraying metallize flash of light look base coat, being coated with efficient has raising by a relatively large margin, makes aluminium powder arrange to be in filming at electrostatic spraying metallic basecoat occasion electrostatic interaction and is arranged (hair as the people is holded up next at electrostatic field) to being coated with Surface Vertical; Diminish reflection of light, and make appearance of film not good.
The plasthetics that plastic material is processed has advantages such as shaping cycle is short, production efficiency is high, in light weight, therefore receives widespread use, and automobile spoiler is exactly wherein a kind of plastic prod.But the feel of common automobile spoiler is general, and luminance brightness is lower, in use surperficial easy abrasion, and the texture that does not possess present people and pursued, value added is not high.Therefore, carry out suitable surface treatment usually and improve its result of use.In the existing method, disclosed the surface property that the method that plastic rubber substrate is carried out surface coated coating is improved plasthetics.But the coating adhesion that this method exists coating to form is low, comes off easily, wears no resistance; Can't life-time service etc. characteristics, and the method for this coating composition, corresponding different plastic rubber substrate need use different coating; Otherwise sticking power maybe be poorer; And for automobile spoiler in irregular shape surface, lacquering technique is difficulty more, and not environmental protection.
Summary of the invention
The objective of the invention is: a kind of prescription and production technique with non-painted automobile spoiler of metalluster is provided; Adopt technology of the present invention to need not that spray treatment is carried out on the surface of automobile spoiler and just have metalluster; The effect of its metalluster can not come off, fade, and appearance is desirable, and the wearing quality of product is strong; The feature of environmental protection is good, to overcome the deficiency of prior art.
The present invention is achieved in that the non-painted automobile spoiler with metalluster, calculates by weight, is made up of 90～100 parts of PP, 5～10 parts of talcum powder and 0.5～1.5 part of aluminium powder; Or form by 90～100 parts of ABS and 0.5～3.5 part of aluminium powder.
The trade mark of described PP is K8303, and the trade mark of ABS is 301.
Aluminium powder is a silver dollar type aluminium powder.Adopt silver dollar type aluminium powder can make the metallic travel of product outstanding.
Production technique with non-painted automobile spoiler of metalluster; Calculate by weight; 90～100 parts of PP and 5～10 parts of talcous mixtures or 90～100 parts of ABS and 0.5～1.5 part of aluminium powder and 5～10 parts of talcum powder are carried out blend, obtain mixture A behind the thorough mixing; Mixture A is joined fusion and extruding pelletization in the twin screw extruder, obtain plastic granule B; Plastic granule B is joined blow molding in the blow moulding machine, obtain interceptor C.
The extrusion temperature that mixture A joins in the twin screw extruder is 170 ℃～230 ℃, the screw speed 300rad/min of twin screw extruder.
Owing to adopted technique scheme; The present invention is employed among PP or the ABS and adds the aluminium powder blend, and it is used to produce automobile spoiler as material, need not the processing that the surface to automobile spoiler sprays and just has metalluster; And the effect of its metalluster can not come off, fade; Even the surface of goods is abraded, weares and teares, its inside also still has metalluster, and need not carry out the process of surface treatment of metallize polychromatic finish to its surface; And wearing quality is strong, especially has excellent light aging resisting property.Adopt the prepared product of the present invention to have metallic travel, and shaping cycle is short, production efficiency is high, in light weight, be not easy to come off; Advantages such as wear resistance is good; Use this automobile spoiler to save this process step that sprays paint in the production process, simplified Production Flow Chart, can significantly reduce production costs; Implement easily, result of use is good.
Experiment according to changing prescription obtains data as shown in the table
