Abstract
The invention relates to a production method of an isolation board of an automobile. The production method is characterized by comprising the following process steps of: (1) sequentially arranging a polypropylene hollow board, an ethylene-vinyl acetate copolymer film and a non-woven fabric from bottom to top and conveying the materials into rotary drums through a conveyer belt for jointing to obtain an isolation board material, wherein the gap between upper and lower rotary drums is between 4.8 and 5.2 millimeters and the temperature of the upper rotary drum is between 110 and 130 DEG C; and (2) putting the jointed isolation board material into a cutting machine and washing excess stocks out by using a cutting die so as to obtain a required isolation board profile, wherein the pressure of the cutting machine is between 0.4 and 0.6 MPa and the depth of the cutting machine is between 0.15 and 0.25 millimeter. The production method has the advantages that: the problem of poor sound insulation performance of the isolation board is solved; stripping performance is superior to that of glue jointing and the phenomena of separation of a plus material from a hollow board and even fall of the plug material are prevented; production is performed by an automatic production line in the entire production process, so that the labor intensity of workers in the production process is lowered greatly and production efficiency is improved; and harmful substances are not produced in the entire production process.
Description
Technical field
The present invention relates to a kind of production method of automobile division board, especially a kind of production method that is used to be installed in division board between automotive seat and the baggage container belongs to the automotive upholstery technical field.
Background technology
The automobile division board generally is installed between automotive seat and the baggage container, plays effect heat insulation, sound insulation.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 more and more higher to the requirement of automotive upholstery.In the prior art, performance figure such as the high sound insulation of automobile division board, low contaminative become bottleneck, are restricting the development of division board.Existing division board normally adopts lining and the hollow sheeting die-cut again technology of glue manual assembly, and this kind technology mainly exists following problem: the requirement of 1, sound insulation index out of reach; 2, fissility is poor, and manual spray sticker closes and causes the product stripping performance poor, and the problem that often has lining to throw off produces; 3, the spray glue stain is big, is unfavorable for the test of VOC performances such as (volatile organic compounds).
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of production method of automobile division board is provided, solved the sound insulation value of division board.
According to technical scheme provided by the invention, the production method of described automobile division board comprises following processing step:
(1) polypropylene hollow sheeting, ethylene-vinyl acetate copolymer film and nonwoven fabrics are placed by order from bottom to up, by fitting between load-transfer device input up-down roller, make the division board material, the gap between described up-down roller is 4.8～5.2mm, and last bowl temperature is 110～130 ℃;
(2) the division board material that posts is put into cutting machine, clout is washed out, obtain the division board profile that needs by the severing mould; Cutting machine pressure is 0.4～0.6Mpa, and the cutting machine degree of depth is 0.15～0.25mm.
Compared with the prior art the present invention has the following advantages: substitute glue with the ethylene-vinyl acetate copolymer film lining and hollow sheeting are fitted, solved the problem of the sound insulation value difference of division board; Stripping performance is better than the glue applying, the phenomenon that lining and hollow sheeting are thrown off even lining comes off can not occur; In whole process of production, take automatic production lines production, greatly reduce working strength of workers in the production process, and improved production efficiency; Whole process of production does not have objectionable impurities to produce environmental protection, pollution-free.
The specific embodiment
The invention will be further described below in conjunction with specific embodiment.
The cutting machine that cutting machine used in the present invention can adopt Shanghai fine horse match package packing machine Co., Ltd to produce;
Ethylene-vinyl acetate copolymer film used in the present invention is called for short the EVA film, and general vinyl acetate (VA) content is 5%～40%.Compare with polyethylene, the EVA film has been owing to introduced VAM in strand, thereby reduced high-crystallinity, improved elasticity, impact resistance, filler intermiscibility and heat seal performance.The present invention is with the hot melt adhesive of EVA film as bonding polyethylene hollow sheeting and nonwoven fabrics, and is free from environmental pollution and safety is higher because the EVA film does not contain solvent, makes production process not have objectionable impurities to produce environmental protection, pollution-free.
Embodiment one: a kind of production method of automobile division board comprises following processing step:
(1) polypropylene hollow sheeting, ethylene-vinyl acetate copolymer film and nonwoven fabrics are placed by order from bottom to up, fitted by load-transfer device input cylinder and make the division board material, the up-down roller gap is 4.8mm, and last bowl temperature is 110 ℃;
(2) the division board material that posts is put into cutting machine, clout is washed out, obtain the division board profile that needs by the severing mould; Cutting machine pressure is 0.4Mpa, and the cutting machine degree of depth is 0.15mm.
Embodiment two: a kind of production method of automobile division board comprises following processing step:
(1) polypropylene hollow sheeting, ethylene-vinyl acetate copolymer film and nonwoven fabrics are placed by order from bottom to up, fitted by load-transfer device input cylinder and make the division board material, the up-down roller gap is 5.2mm, and last bowl temperature is 130 ℃;
(2) the division board material that posts is put into cutting machine, clout is washed out, obtain the division board profile that needs by the severing mould; Cutting machine pressure is 0.6Mpa, and the cutting machine degree of depth is 0.25mm.
Embodiment three: a kind of production method of automobile division board comprises following processing step:
(1) polypropylene hollow sheeting, ethylene-vinyl acetate copolymer film and nonwoven fabrics are placed by order from bottom to up, fitted by load-transfer device input cylinder and make the division board material, the up-down roller gap is 5mm, and last bowl temperature is 120 ℃;
(2) the division board material that posts is put into cutting machine, clout is washed out, obtain the division board profile that needs by the severing mould; Cutting machine pressure is 0.5Mpa, and the cutting machine degree of depth is 0.2mm.
Claims (1)
