Abstract
The invention relates to a production method used for processing automobile interior ceilings via cold mold method, and belongs to the technical field of automobile ceiling interior production. According to the production method, thermoplastic polyurethane hard foam boards are taken as a framework material, glass fiber is taken as a reinforcing material, and solid hot melt adhesive is taken as an adhesive so as to produce a composite board material via cold forming. The production method comprises steps of base material combination, compression moulding forming, and finished product producing successively. The obtained composite board material possesses excellent sound absorption performance, thermal insulation performance, self supporting performance, and environmental protection performance, and extremely high rigidity and dimensional stability, and is suitable for design and producing of luxurious automobile interior ceilings.
Description
Technical field
The present invention relates to a kind of cold modulus method processing automobile inner decorative ceiling production technology, belong to ornaments processing technical field in vehicle ceiling.
Background technology
The framework material of orthodox car inner decorative ceiling mainly uses cardboard and PS plate, not easily processing and manufacturing, and the inner decorative ceiling produced is yielding, the moisture absorption, and its sound-absorbing, heat insulation, rigidity, dimensional stability and environmental-protecting performance are all poor, of low grade.Therefore, people expect a kind of process stabilizing, the production technology of function admirable automotive interior roof can overcome above-mentioned defect.
Summary of the invention
For overcoming the deficiency of above-mentioned prior art, the present invention proposes a kind of cold modulus method processing automobile inner decorative ceiling production technology.
For achieving the above object, the technical solution used in the present invention is: a kind of cold modulus method processing automobile inner decorative ceiling production technology, inner decorative ceiling is framework material by the thermoplasticity polyurethane plate that hard bubbles, take glass fibre as reinforcing material, be composite processing with non-woven fabrics and inner decoration facing, it is characterized in that, production technology adopts cold modulus method production technology, in turn include the following steps: 1) base material compound: non-woven fabrics is unreeled lay on workbench, non-woven fabrics is sowed solids hot melt adhesive and glass fibre, then thermoplastic hard polyurethane cystosepiment (being called for short PU plate) is placed above, solids hot melt adhesive and glass fibre is sowed again on PU plate, then through heater plate to 150-260 DEG C, roll-in compound is carried out under the pressure of 0.4-0.6mpa, cooled composite board is inner decorative ceiling base material, 2) cold mold forming: inner decoration facing is mated formation on the punch of ceiling mould, die is put into after more above-mentioned base material being heated 30-100S under the high temperature of 200-400 DEG C, matched moulds, cold forming is carried out shaping under 5-15MPa pressure, after pressurize 30-100S, Qi Mo, pickup, the pressing of taking-up is inner decorative ceiling semi-finished product, 3) finished product makes: above-mentioned inner decorative ceiling semi-finished product are carried out cut edge, cut hole, finishing, and the ceiling assembly installed after ceiling accessory is inner decorative ceiling finished product of the present invention.
The invention has the beneficial effects as follows: selection is unique, simple process is easy to operate, the inner decorative ceiling produced has excellent sound-absorbing, heat insulation, damping, light weight, protection against the tide, preventing microorganism, anti-fouling performance, and the gas permeability of excellence, weather resisteant and dimensional stability, there is stronger self-supporting performance, not yielding, product specification is high.
Detailed description of the invention
Below in conjunction with detailed description of the invention, it is set forth in further detail.
Cold modulus method processing automobile inner decorative ceiling production technology of the present invention is framework material by the thermoplastic polyurethane plate that hard bubbles, take glass fibre as reinforcing material, with non-woven fabrics and inner decoration facing for composite, be the composite board that binding agent is made with solid thermal melten gel, with cold modulus method method of forming processing and fabricating, specific as follows:
First non-woven fabrics is unreeled lay on workbench, non-woven fabrics is sowed solids hot melt adhesive and glass fibre, then thermoplastic hard polyurethane cystosepiment (being called for short PU plate) is placed above, solids hot melt adhesive and glass fibre is sowed again on PU plate, then through heater plate to 150-260 DEG C, under the pressure of 0.4-0.6mpa, carry out roll-in compound, cooled composite board is inner decorative ceiling base material, deposits stand-by after being cut; Then cold mould moulding process is entered, first inner decoration facing is mated formation on the punch of ceiling mould, die is put into after again the base material of above-mentioned cutting being heated 30-100S under the high temperature of 200-400 DEG C, it is shaping that matched moulds carries out cold forming under 5-15MPa pressure, after pressurize 30-100S, Qi Mo, pickup, the molded product of taking-up is inner decorative ceiling semi-finished product; Be finally processed finished products, the inner decorative ceiling semi-finished product of processing are carried out cut edge, cut hole and finishing, the ceiling assembly installed after ceiling accessory is inner decorative ceiling finished product of the present invention.
The inner decorative ceiling finished product good looking appearance that above-described embodiment is obtained, excellent performance, safe and reliable, after ceiling decoration in car, can greatly improve passenger car class, increase the comfortable and satisfied of driver.
