Abstract
A composite material (fabric) for internal decoration of car is composed of face layer, substrate and adhesive layer. It is made up through adding thermoplastic resin to a screw extruder, heating, extruding out by an electrothermal die head with a slit while coating on the back of face material, sticking the back of face material to the front of substrate, and rolling. Its advantages are high stripping strength and no residual harmful substance.
Description
Technical field
The present invention relates in the textile industry fabrics for industrial use manufacturing industry manufacture method of composite material for decorating automobile inside.This composite is widely used in the car interior trim and carpet etc. is decorated in other moistureproof pavings.
Background technology
Because the World Economics fast development improves constantly with living standards of the people, automobile industry development, especially car production are maked rapid progress, and vehicle is brought in constant renewal in.Require also more and more higher to the interior material that is complementary with vehicle.
Owing to people require from originally only considering that beautiful design transferred to the requirement to its interior material car, require material to have heat insulation, noise reduction, function such as shockproof, fire-retardant and both artistic and practical simultaneously.The one-component material can not meet the demands in recent years, people adopt textile material to become interior material with other base material through Compound Machining usually, in compound processing course, need two or more base materials (as textile material+textile material or textile material+plastics+rubber) are composited through adhesive.But solvent for use type adhesive contains a large amount of volatile harmful organic solvents, overflows and contaminated environment in process of manufacture, and is unclean if solvent takes off, and remains in the environment that also can pollute use in the composite.
Pressed film method and inspergation have occurred at the manufacture field of automotive interior material the eighties in 20 century abroad.Pressed film method is earlier high density polyethylene (HDPE) (HDPE) to be made breathable film, and then it being clipped in needs the middle heating and melting of two kinds of compound base materials to make jointing material, is compacted into composite at last; Inspergation is earlier low-melting-point resin (as copolyamide) to be clayed into power, and it is compound that metering is sprinkling upon the substrate surface heating equably then.Above-mentioned two kinds of methods, though all utilize the viscoplasticity principle of some resin melt to make adhesive, solvent-free waste gas all needs granular resin is made breathable film earlier or made powder, and then is used as the adhesive of composite base material, operation is loaded down with trivial details, long flow path.
Summary of the invention
The problem to be solved in the present invention provides a kind ofly can make the production process flow process of the interior trim composite that automobile uses short, efficient is high, quality good, pollute few manufacture method.
For addressing this problem the following scheme that adopted:
Directly adopt plastics level low melting point thermoplastic resin particle to add screw extruder as adhesive, be heated to 170～270 ℃ within it continuously equably and become melt, continuous metering and be extruded into melt films subsequently by the die head that is connected with the extruder extrusion, melt films is coated the back side of surface layer base material, fits after the roll pressure rolling combined shaping of compounding machine in the back side of the surface layer base material of coating melt films and the front of bottom substrate; Then cut redundance, be processed into the composite of regulation shape and size with the melt cut forming-tool.
In the above-mentioned operation, screw extruder melt extrusion temperature is 240～260 ℃, 250～270 ℃ of the die head electric heating temperature of melt extrusion film.The outlet of die head and screw extruder links to each other, and die head exit (being die orifice) length is consistent with institute adhesive substrate width.The die orifice width is according to melt films thickness, i.e. coating layer thickness and regulating, and scope is 0.1～1mm.Compounding machine roll linear velocity 3～6m/min, nip pressure 0.2～0.8MPa.The chill roll water temperature is a normal temperature.Pressure 0.5～the 1.0MPa of melt cut machine, melt cut electric current 100～180A, melt cut voltage 20～30V.
Advantage of the present invention is: owing to directly adopt behind the low melting point thermoplastic resin heating and melting as adhesive, directly coat on the base material, two kinds of base materials are fitted after one step of pressure rolling is made composite material for decorating automobile inside, this compares technology with prior system film or powder process as adhesive and shortens greatly, and whole process of production is difficult for producing waste gas, and is low in the pollution of the environment; Compare with adopting solvent type adhesive, record 17.6 times of the peel strength raisings of the product of producing, 1 times of bending rigidity raising, and residual harmful chemical substance not.
The specific embodiment
Base materials employed: the surface layer base material is 900g/m
2Polypropylene fibre blanket, bottom substrate are 600g/m
2The polypropylene fibre felt.
Device therefor: screw extruder is the SJ type, and compounding machine is the SDF type, and the melt cut machine is the MC-B type.
Adhesive therefor: the section of plastics grade polypropylene, also available and base material non-homogeneous adhesive is cut into slices as polyethylene.
165 ℃ in screw extruder temperature one district, 195 ℃ in two districts, 218 ℃ in three districts, 245 ℃ in four districts, 260 ℃ in five districts, six districts.
265 ℃ of die head temperatures, compounding machine speed 5.5m/min, coated film thickness 0.12mm, compounding machine nip pressure 0.5MPa, and by room temperature water circulation cooling.
When the acrylic resin of molten condition is extruded by die orifice, form melt films and coat the above-mentioned polypropylene fibre blanket back side, fit with the polypropylene fibre felt is positive again, become composite through the pressure rolling of compounding machine roll.Follow into molten required form and the big or small finished product of being cut into of cutting machine.
