Abstract
A die press technology for forming a plastic film compounded steel plate features that ordinary steel plate is covered by a decorative plastic film and then adhered or thermally pressed to form a plastic film compounded steel plate, and obtained compounded steel plate is heated to 38-150 deg.C while thermally die-pressed under the pressure of 15-25 kg/sq.cm and 2-8 mm of tension depth. Its advantages are simple technology, low energy consumption, high rate of finished products, low cost and no breaking and no decolouring of plastic film.
Description
The present invention relates to constitute the laminar product method for processing forming that thin layer fits by predetermined substance, especially a kind of die press technology for forming plastic film compounded steel plate a kind of the composition as the thin layer major part and with another layer by metal in fact.
Processing and manufacturings such as the shell of more existing household electrical appliance and Theft-proof iron door panel all are by earlier iron plate or steel plate compression molding, rear surface being handled armor coated order and finished; and coated protective layer need pass through high-temperature baking, solidification process toward contact; a large amount of energy had both been wasted; occupy many spaces again, also cause environmental pollution easily.This traditional processing technology process period is long, the production cost height, and also product quality also is difficult to control and assurance.Chinese patent CN2288835A discloses a kind of " PVC-PET light film compounded steel plate "; its essential characteristic is to establish the chemical treatment layer and add the clad steel plate of formation such as adhesive layer, PVC thin layer and bright layer with ornamental protective layer on basic unit's steel plate, can directly make product or semi-finished product.But, can only carry out simple crimping, brake forming processing at present, and be not suitable for carrying out strong impact force and hale the compression molding processing of stretching because the adhesion strength and the hot strength of its each layer are all inequality.And in process, break easily and peel off or variable color.
Purpose of the present invention just is to overcome above-mentioned the deficiencies in the prior art part; propose a kind of with short production cycle; processing and manufacturing is easy; obviously energy-saving and cost-reducing; the rate that manufactures a finished product height, the quality control performance is good, and production cost is low; and the plastic film protective layer do not break and peels off yet nondiscolouring, only needs once molding formed die press technology for forming plastic film compounded steel plate.
Purpose of the present invention can reach by implementing following technical proposal: will be coated with ornamental PVC or PET plastic foil and also be heated in 38～150 ℃ of temperature ranges through adhesive plastic film compounded steel plate bonding or that the high temperature pressing forms on general steel plate, carry out one-time formed hot-forming processing under 15～25 kilograms every square centimeter pressure, its mold pressing stretching depth is 2～8 millimeters.Be to obtain better technique effect, the used mould of above-mentioned mold pressing also be heated to the corresponding temperature of clad steel plate be good; The gross thickness of described clad steel plate is preferably 0.5～1.0 millimeter; The preferred temperature of above-mentioned heating clad steel plate and mould is 80 ℃.
Below for non-limiting embodiment of the present invention: with gross thickness is that 1 millimeter hot pressing PVC clad steel plate is heated to 80 ℃ in electrical drying oven, simultaneously, processing mold also is heated to 80 ℃, under 20 kilograms every square centimeter pressure that above-mentioned pre-ripe clad steel plate is once molding formed then, make the Theft-proof Door Panel that becomes the band ridge design.Its mold pressing stretching depth is 5 millimeters, and the product that this process stempressing goes out is because the synchro-draw of thermoplasticity diaphragm, can not produce to break, peel off and phenomenon such as variable color, and cleaning surfaces, smooth as new, and can install and use immediately.
The present invention compared with prior art, have with short production cycle, the processing and manufacturing facility, energy-saving and cost-reducing obviously, The rate that manufactures a finished product height, the quality control performance is good, and production cost is low, and the plastic film protective layer can not break and peels off and not The meeting variable color only needs the characteristics such as once molding formed, is fit to process the products such as appliance shell and Theft-proof Door Panel.
