Abstract
The invention relates to a method for producing an automotive rear shelf. The method is characterized by comprising the following steps of: (1) heating: hanging polypropylene sheets in a two-layer drying oven and heating, wherein the temperature of an upper-layer drying oven of the two-layer drying oven is between 240 and 260 DEG C; the temperature of a lower-layer drying oven of the two-layer drying oven is between 325 and 345 DEG C; and the heating time is 85 to 95 seconds; (2) pressing and forming: laying a fabric on two layers of PP sheets flatly, and pressing and forming the fabric in a die to obtain a half-finished product, wherein the pressure during pressing and forming is 70 to 90kg/cm<2>, and the forming time is 60 to 70 seconds; (3) cooling and shaping: cooling and shaping the half-finished product at the normal temperature, wherein the cooling time is 30 to 50 seconds; (4) installing accessories: installing the accessories on the half-finished product to obtain an automotive rear shelf finished product; and (5) examining and packing, wherein the fabric is a non-woven fabric, and the PP sheets are PP wood powder sheets with glue. The method ensures the performance indexes of light weight, high strength, difficult contraction distortion and the like of a rear shelf, greatly reduces the weight of the rear shelf, and meets the requirement for lightweight vehicle design; and as the material has a double-layer wood powder sheet structure, the product is fuller.
Description
Technical field
The present invention relates to a kind of working method of vehicle back-shelf board, especially a kind of be used to be installed in automotive seat after, the working method of the back-shelf board of rear seat windscreen below, belong to the automotive upholstery technical field.
Background technology
Automotive upholstery generally is installed on automobile top, baggage container, operator's compartment and plays heat insulation, sound insulation, attractive in appearance and practical effect.More and more pursuing High Performance, environment-friendly type, energy-saving, lightweight, personalized epoch, the interior trim of automobile is the same with the profile of automobile, becomes the key factor that people choose automobile.Therefore also increasingly high to the requirement of automotive upholstery.In the prior art, performance figure such as the low grammes per square metre of back-shelf board, high strength become bottleneck, are restricting the development of back-shelf board.The most individual layer wood flour boards that adopt of existing back-shelf board heat directly compression moulding of back, and its shortcoming is.Weight is big, price is high, thin thickness, shrinkage distortion big (can not satisfy the shape need of some automobile to back-shelf board).
Summary of the invention
The objective of the invention is to overcome the deficiency that exists in the prior art, provide a kind of intensity high, in light weight, the working method of on-deformable vehicle back-shelf board.
According to technical scheme provided by the invention, the working method of said vehicle back-shelf board is characterized in that, may further comprise the steps:
(1) heat: polypropylene board is suspended in the double-deck baking oven heats, double-deck baking oven upper strata oven temperature is 240～260 ℃, and lower floor's baking temperature is 325～345 ℃, and time of heat is 85～95 seconds;
(2) compression moulding: lining is tiled on the two layers of polypropylene plate, processes type at mould inner pressure and obtain half-blank, the pressure of compression moulding is 70～90kg/cm
2, molding time is 60～70 seconds;
(3) cooling and shaping: with half-blank cooling and shaping at normal temperatures, hardening time is 30～50 seconds;
(4) annex is installed: annex is installed in obtains the vehicle back-shelf board finished product on the half-blank.
(5) check, vanning.
Said lining is a nonwoven fabrics.
Said polypropylene board is band glue PP wood flour board.
The invention solves back-shelf board lightweight, high strength, be difficult for performance figure such as shrinkage distortion; Greatly reduce the weight of back-shelf board, satisfied the requirement of car load light-weight design; Material adopts double-deck wood flour board structure, makes product fuller, more can embody the moulding of outward appearance, and not yielding, moulding Detroit automation, process stabilizing; The rigidity of product is high, and intensity is big, can not fracture, ftracture; Practiced thrift manufacturing cost; The product whole process of production does not have objectionable impurities to produce, and belongs to environment-friendly products.
The specific embodiment
Below in conjunction with specific embodiment the present invention is described further.
The double-deck baking oven that double-deck baking oven used herein can use the inferior safe baking oven originating firm in Wujiang to produce.
