Abstract
The invention discloses a novel trim ceiling of a superior quality car and a production process, and belongs to the technical field of production of car ceiling trims. The novel trim ceiling of the superior quality car is a composite plate produced by using a thermoplastic polyurethane rigid foam plate as a skeleton material, using glass fibers as reinforcing materials and using solid hot melt glue as adhesive through a cold mold forming method; and the production process comprises three process steps of base material compounding, compression molding and finished product manufacturing in sequence. The novel trim ceiling of the superior quality car has such excellent performances as sound absorption, heat insulation, self support and environmental protection, has higher rigidity and size stability; and the production process is suitable for design and manufacturing of the novel trim ceiling of the superior quality car.
Description
Technical field
The present invention relates to a kind of novel inner decorative ceiling and production technology of high-grade car, 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 novel inner decorative ceiling and production technology of high-grade car.
For achieving the above object, the technical solution used in the present invention is: a kind of novel inner decorative ceiling of high-grade car and 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 includes 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, under the pressure of 0.4-0.6mpa, carry out roll-in compound, 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.
The novel inner decorative ceiling of high-grade car of the present invention and production technology are 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 and detached moulding process is entered, first inner decoration facing is mated formation on the punch of ceiling mould, die is put into again after heating 30-100S under the high temperature of the base material 200-400 of above-mentioned cutting 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.
