Abstract
The present invention discloses automobile ceiling and its production process. The automobile ceiling is composite plate produced with thermoplastic polyurethane as the skeleton material, glass fiber as the reinforcing material, and solid hot molten glue or liquid polyurethane glue as the adhesive. The production process is one hot mold or cold mold process including the steps of compounding base material, molding to form and making product. The automobile ceiling has the functions of absorbing sound, isolating heat and self supporting, possesses the advantages of environment friendship, high rigidity and high size stability, and is especially suitable for car.
Description
One, technical field
The invention discloses the production technology of a kind of production technology of vehicle interior ceiling, particularly a kind of automobile ceiling, belong to ornaments processing technical field in the vehicle ceiling.
Two, background technology
Orthodox car inner decorative ceiling, its framework material mainly use cardboard and PS plate, are difficult for processing and manufacturing, the inner decorative ceiling of producing is yielding, the moisture absorption, its sound-absorbing, heat insulation, rigidity, dimensional stability and environmental-protecting performance are all relatively poor, belong to low-grade, be not the selected obsolete product of modern passenger car.
Three, summary of the invention
Purpose of the present invention is intended to overcome the deficiency of above-mentioned prior art, discloses the production technology of automobile ceiling of the top grade of a kind of process stabilizing, function admirable.
For achieving the above object, the technical solution used in the present invention is: a kind of production technology of automobile ceiling, inner decorative ceiling is to be framework material by the thermoplastic polyurethane plate that hard bubbles, with the glass fibre is reinforcing material, with nonwoven and inner decoration facing is that composite processes, its special character is that production technology adopts cold modulus method production technology, in turn includes the following steps:
1, base material is compound: nonwoven is unreeled lay to workbench, on nonwoven, sow solids hot melt adhesive and glass fibre, place thermoplastic hard polyurethane cystosepiment (being called for short the PU plate) then in the above, on the PU plate, sow solids hot melt adhesive and glass fibre again, be heated to 150-260 ℃ through heating plate then, it is compound to carry out roll-in under the pressure of 0.4-0.6mpa, and cooled composite board is the inner decorative ceiling base material;
2, cold mold forming: inner decoration facing is mated formation on the punch of ceiling mould, again above-mentioned base material is being put into die behind the heating 30-100S under 200-400 ℃ the high temperature, matched moulds, under 5-15MPa pressure, carry out the cold forming moulding, behind the pressurize 30-100S, Qi Mo, pickup, the pressing of taking-up is the inner decorative ceiling semi-finished product;
3, finished product is made: will above-mentioned inner decorative ceiling semi-finished product carry out cut edge, cut the hole, finishing, the ceiling assembly behind the installation ceiling annex is inner decorative ceiling finished product of the present invention.
The good effect that compared with the prior art the present invention has is: the selection uniqueness, technology is simple and easy to operate, the inner decorative ceiling of producing has excellent sound-absorbing, heat insulation, damping, light weight, protection against the tide, preventing microorganism, anti-fouling performance, and excellent gas permeability, weatherability and dimensional stability, stronger self-supporting performance is arranged, not yielding, the product specification height is novel inner decorative ceiling and the production technology that is suitable for high-grade car.
Four, the specific embodiment
For understanding the present invention better, it is done to set forth in further detail below in conjunction with the specific embodiment.
Automobile ceiling of the present invention is to be framework material by the thermoplastic polyurethane plate that hard bubbles, with the glass fibre is reinforcing material, with nonwoven and inner decoration facing is composite, with the solid thermal melten gel is the composite board that binding agent is made, form with cold modulus method method of forming processing and fabricating, specific as follows:
At first nonwoven is unreeled lay to workbench, on nonwoven, sow solids hot melt adhesive and glass fibre, place thermoplastic hard polyurethane cystosepiment (being called for short the PU plate) then in the above, on the PU plate, sow solids hot melt adhesive and glass fibre again, be heated to 150-260 ℃ through heating plate then, it is compound to carry out roll-in under the pressure of 0.4-0.6mpa, and cooled composite board is the inner decorative ceiling base material, stand-by with depositing after its cutting; Enter cold and detached moulding process then, earlier inner decoration facing is mated formation on the punch of ceiling mould, again the base material of above-mentioned cutting is being put into die behind the heating 30-100S under 200-400 ℃ the high temperature, matched moulds carries out the cold forming moulding under 5-15MPa pressure, behind the pressurize 30-100S, Qi Mo, pickup, the molded product of taking-up is the inner decorative ceiling semi-finished product; Be processed finished products at last, the inner decorative ceiling semi-finished product of processing carried out cut edge, cut hole and finishing that the ceiling assembly behind the installation ceiling annex is inner decorative ceiling finished product of the present invention.
The inner decorative ceiling finished product good looking appearance that the foregoing description makes, excellent performance, safe and reliable, be used in the car can improving the passenger car class greatly behind the ceiling decoration, increase the comfortable and satisfied of driver.
