Description
Technical field:
The present invention relates to roof of the vehicle interior trim technical field, specifically a kind of PP glass-fiber-plate roof of the vehicle and production method thereof, be particularly suited for soft bubble fabric, the sedan limousine inner decorative ceiling of band skylight mechanism.
Background technology:
Orthodox car ceiling is mainly based on PU base material, has the advantages such as excellent sound-absorbing, heat insulation, easy processing, but there is also the problem such as feature of environmental protection deviation, ceiling rapid wear.PP glass-fiber-plate base material is the advantage that a kind of brand-new material just embodies it: material is simple, is mainly composed of in polypropylene and glass fibre, raw material and the course of processing basic VOC free composition；Toughness of material is good, by damaging under External Force Acting and can be restored back to original state state.In view of above advantage, PP glass-fiber-plate base material is more and more applied on roof of the vehicle.Current PP glass-fiber-plate matrix structure consists of: bottom non-woven fabrics, bottom glued membrane, PP Chopped Strand Mat, upper strata glued membrane or rubber powder, but the PP glass-fiber-plate ceiling of this structure also exists bigger weak point in the application: 1, difficulty of processing is big, outward appearance is poor, especially carry soft bubble fabric, after mold pressing, there will be the shape that is uneven；2, skylight opening bound edge operating difficulties；Clearstory ceiling is because reasons in structure, and major part needs to carry out bound edge operation, but PP glass-fiber-plate base material is difficult to separate after molding at skylight opening, and if separating effect is bad also result in bound edge after present wavy injustice.
Summary of the invention:
It is an object of the invention to overcome the deficiency of above-mentioned prior art, and a kind of PP glass-fiber-plate roof of the vehicle is provided.
It is a further object of the present invention to provide the production method of a kind of PP glass-fiber-plate roof of the vehicle.
Present invention mainly solves the problem such as appearance poor and bound edge difficulty after existing PP glass-fiber-plate base material molds.
The technical scheme is that, a kind of PP glass-fiber-plate roof of the vehicle, it is characterized in that, is made up of bottom non-woven fabrics, bottom glued membrane, PP Chopped Strand Mat, upper strata non-woven fabrics, upper strata glued membrane and fabric；By bottom non-woven fabrics, bottom glued membrane, PP Chopped Strand Mat, upper strata non-woven fabrics, upper strata glued membrane, it is complex as PP glass-fiber-plate base material by compounding machine；By baking oven for heating, by fluffy for base material thermoplastic, by mould, the base material after heating is integrated with fabric mold pressing；Then Water Cutting removes invalid overlap；There is the ceiling of skylight frame, carry out cutting bound edge work.
Further, described bottom non-woven fabrics is spun-laced nonwoven fabric, spun-bonded non-woven fabrics, fabric hot rolled nonwoven fabrics or needle punched non-woven fabrics one therein, grammes per square metre 40-100 gram/flat.
Further, described bottom glued membrane is modified poly ethylene glued membrane or modified polypropene glued membrane, grammes per square metre 40-100g gram/flat.
Further, described PP Chopped Strand Mat is that by acupuncture knitmesh mode, PP fiber and glass fibre are made felted, and wherein PP and glass part by weight are between 4:6---6:4, the grammes per square metre of PP Chopped Strand Mat 800-1100 gram/flat.
Further, described upper strata non-woven fabrics is spun-laced nonwoven fabric, spun-bonded non-woven fabrics or fabric hot rolled nonwoven fabrics one therein, grammes per square metre 20-60 gram/flat.
Further, described upper strata glued membrane is modified poly ethylene glued membrane or modified polypropene glued membrane, grammes per square metre 50-100 gram/flat.
Further, described fabric is three layers of knitting fabric or non-woven fabric, grammes per square metre 200-350 gram/flat.
The production method of the PP glass-fiber-plate roof of the vehicle of the present invention, it is characterized in that, comprises the following steps:
A chooses bottom non-woven fabrics, bottom glued membrane, PP Chopped Strand Mat, upper strata non-woven fabrics, upper strata glued membrane, is complex as PP glass-fiber-plate base material by compounding machine；
B passes through baking oven for heating, by fluffy for base material thermoplastic, is integrated with fabric mold pressing by the base material after heating by mould；
C Water Cutting removes invalid overlap；
D has the ceiling of skylight frame, carries out cutting bound edge work.
Compared with the prior art a kind of PP glass-fiber-plate roof of the vehicle of the present invention and production method thereof have prominent substantive distinguishing features and marked improvement, one layer of upper strata non-woven fabrics is increased between upper strata glued membrane and PP Chopped Strand Mat, by this layer of non-woven fabrics optimization, on the one hand the flatness on surface in base material heating process is ensured, finally mold out the preferable ceiling of outward appearance, on the other hand it is easily delaminated also by between upper strata nonwoven layer and PP glass flaggy, it is finally reached and is prone to the operation of torn edges bound edge, finally realize the bound edge operation of sky window position, optimize the torn edges condition improvement cutting bound edge effect of base material.
