Abstract
The invention relates to a method for producing a composite layer substrate of a trunk ornamental plate for an automobile, which can be particularly applied to manufacturing a composite layer of the trunk ornamental plate for the automobile. The method is characterized by comprising the following steps: taking PET as a bonding substrate; coating PP on the bonding area on the surface of a PET blanket; putting into an oven, heating, drying and taking out; and then pressing the substrate by a presser, and cutting by a cooling water cutter to obtain a finished product. The invention has simple technology and equipment requirement, stable technology, avoids investing for establishing large-scale equipment, ensures safety and accuracy of operation, and improves the operating efficiency. The finished product has the advantages of high resistance to high and low temperature, ageing resistance, good bending resistance, high rigidity and no breakage or droop; no semi-finished product accumulatesduring transportation so that the manufacturing cost is saved; and no harmful matter is generated in the whole production process.
Description
Technical field
The present invention relates to a kind of production method of composite layer substrate of trunk ornamental plate for automobile, specifically can be applicable to make in the middle of the car trunk plaque composite bed.
Background technology
PET (polyethylene terephthalate) has the high resiliency feature that general material lacks as a kind of high molecular compound of ultra high molecular weight.In wider temperature range, has excellent physical and mechanical properties.Thereby have certain hysteresis effect to have the sound insulation shock-absorbing function to alternation and vibration stress and fluctuation, advantages such as its resistance to effect of heat, chemical proofing, obdurability, electrical insulating property, safety have also promoted popularizing of PET industrial expansion and goods thereof in addition.But the PET impact property is poor, and is a little less than the rigidity, yielding.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, thereby a kind of production method of composite layer substrate of trunk ornamental plate for automobile is provided, its manufactured product has very high bind strength, resistant of high or low temperature, resistance to ag(e)ing, anti-good bending, good rigidly.
According to technical scheme provided by the invention, the production method of described composite layer substrate of trunk ornamental plate for automobile comprises the steps:
(1) the PET fiber is passed through successively feeding, shredding, combing, lapping and acupuncture step, form PET face blanket, the grammes per square metre of described PET face blanket is 180～220g/m
2
(2) PP (polypropylene) with molten condition extrudes on the surface that is coated in described PET face blanket, until covering described surface fully uniformly; The grammes per square metre of described PP is 1500～1700g/m
2After treating the PP cooling, described PET face blanket and described PP are bonding fully, form composite bed; Total grammes per square metre 1700～1900g/m of described composite bed
2, thickness is 3.5～4.5mm;
(3) baking oven of described composite bed being put into 390～410 ℃ toasted 110～130 seconds, reached at 180～220 o'clock in the composite bed surface temperature, took out described composite bed;
(4) adopt 280～320 tons hydraulic forming machine, above-mentioned composite bed is made type at mould inner pressure; Pressure control is at 6～7mpa, and molding time is controlled at 55～65S; The cooling back forms half-blank;
(5) water cutter cutting: above-mentioned half-blank is placed on the high pressure water cutting machine, carries out the cutting of water cutter by the high pressure water cutting machine; Cutting hydraulic pressure is controlled at 40000～50000psi, and the Cutting Gas pressure-controlled forms finished product at 0.55～0.65mpa.
The composite material of the PET+PP that the present invention utilizes.Production technology and equipment require simple, have avoided the input of investing in and revising mould repeatedly of main equipment.Manufactured product has very high resistant of high or low temperature, resistance to ag(e)ing, and anti-good bending, and bind strength and rigidity significantly increase.Can be used to prepare the composite base material of car trunk plaque, have cooresponding actual benefit.
