Description

A kind of roof of the vehicle high intensity sandwich base material and its production method
Technical field
The present invention relates to roof of the vehicle base material processing technique field, more specifically to a kind of roof of the vehicle with high-strength Spend sandwich base material and its production method.
Background technology
At present, the automobile ceiling sandwich base material of PU+GF+PE structures has two kinds of processing technologys, i.e., using PE Or the PP thermoplasticity dry process bonded and the thermosetting wet processing being molded using PU reactions.
Existing roof of the vehicle sandwich base material, it is mostly be using non-woven fabrics, rubber powder, glass, glued membrane, PU plate shapes into Composite construction, this composite construction needs have good cohesive force between each layer, while need to have high intensity and springform Amount, wherein the intensity of this composite construction is provided mainly by PU plates and glass, but due to dry formed automotive ceiling sandwich The process conditions limitation of base material, when PU panel densities are higher than 40kg/m3When, sandwich substrate forming can be impacted, its table Easily there is the phenomenon of injustice in face；And when glass fiber content is too high, the addition of rubber powder and glued membrane will also increase on year-on-year basis, input cost Increase, otherwise can cause the problem of sandwich base material cohesive force declines.Therefore, it is existing for the higher roof of the vehicle of intensity requirement Some technologies can not further be increased roof of the vehicle intensity.For this problem, a kind of vehicle top how is researched and developed The problem of canopy is current urgent need to resolve with the good sandwich base material of high intensity, cohesive force and its production method.
Sandwich base material its production method that roof of the vehicle is made of polyurethane plate mainly has following several：
Through retrieval, Chinese patent CN101088742, be on automobile ceiling production technology, the process production Multilayer composite board of polyurethane is to unreel non-woven fabrics on the conveyer belt of recombination line, sow or lay successively short glass fiber, Hot melt adhesive stick, PU plates, short glass fiber, hot melt adhesive stick, are heated to 150-260 DEG C, in certain pressure through recombination line Under it is heated, cooling after composite board is made.Although the production technology is to go out Rigid foam polyurethane by One-step production, by The hot melt adhesive stick used in production process is poor with polyurethane cohesive force, and glass stratum reticulare is easily layered up and down.
Chinese patent CN101628498, is the production method on polyurethane plate for automobile ceiling：Will be first multiple Non-woven fabrics, short glass fiber, hot-melt adhesive powder are tiled or sowed on the crawler belt of conjunction machine, then in certain temperature and pressure Under obtain glue glass cloth；Then tile glue glass cloth, adhesive film, rigid polyurethane successively from bottom to top on the workbench of composite production line Plate is steeped, then short glass fiber, hot-melt adhesive powder are sowed successively on hard polyurethane foam plate, tile hot melt adhesive film, certain temperature Multilayer composite board of polyurethane is obtained with compound under pressure, this usual intensity of composite board and modulus of elasticity have certain limitation.
Chinese patent CN2011103980826, this application case discloses a kind of roof of the vehicle sandwich base material and its life Production method, it is by I layers of non-woven fabrics, the first short glass fiber layer, the first PUR bisque, the first hot melt adhesive film to be characterized in it Layer, PU flaggies, the second short glass fiber layer, the first type sandwich base material of the second PUR bisque composition；In first type sandwich base The second PUR film layer and the 3rd PUR bisque are set on material successively, the 4th hot-melt adhesive powder is set successively under first type sandwich base material II layers of layer, the 3rd short glass fiber and non-woven fabrics；Its production method is that each layer is combined into roof of the vehicle sandwich through roll-in Base material, but the sandwich base material can not generally meet the requirement of roof of the vehicle high intensity under special circumstances.

77 μm of α ＜ the 3rd PE rubber powders account for mass percent≤13% of total 3rd PE rubber powders, and the present embodiment utilizes different-grain diameter α） PE rubber powders and different quality percentage, on the one hand avoid PE rubber powder sizes（α）Too small, particle diameter（α）Too small PE glue When silty amount is more, the dusting amount of PE rubber powders is difficult to control during PE rubber powder dustings are carried out, and the dusting amount of PE rubber powders is missed The larger phenomenon of difference；On the other hand PE rubber powder sizes are avoided（α）Excessive, particle diameter（α）When excessive PE rubber powder quality is more, Carry out after PE rubber powder dustings, excessive PE rubber powders are difficult the phenomenon melted during heating composite.The present invention is by using difference Particle diameter（α）PE rubber powders and different quality percentage so that particle diameter of different sizes（α）PE rubber powders during unrestrained energy Enough make particle diameter（α）Appropriate PE rubber powders are unrestrained uniform, and it is good that rear effect is dissolved in heating；Simultaneously during PE rubber powder dustings are carried out Good control can be carried out to the dusting amount of PE rubber powders.
The present embodiment is by controlling the 2nd PET non-woven fabrics, the weight per unit area of the 3rd PE adhesive films or PP adhesive films, the Two PET non-woven fabrics size changing rates, the Cutting Length of the 3rd GF glasses, the particle diameter of the 3rd PE rubber powders（α）The parameters such as distribution so that While glass strengthens cloth 9 with higher intensity, combined with higher interlayer adhesion and with roof of the vehicle facial ornament Cohesive force.
（2）Make high intensity sandwich base material：Tile the first PET non-woven fabrics on the conveyer belt of composite production line, then It is sowed or laid successively above the first GF glasses, the first PE rubber powders, the first PE glued membranes or PP glued membranes, glass and strengthens cloth 9, PU Plate, the 2nd GF glasses, the 2nd PE rubber powders, glass strengthen cloth 9, the 2nd PE glued membranes or PP glued membranes formation composite II, then adopt 30-80s is heated to composite II with 180-250 DEG C of temperature, roll-in finally is carried out to composite II under 7-12MPa pressure It is compound, high intensity sandwich base material is made after cooling.
Vertical well known, on the one hand roof of the vehicle sandwich base material will ensure its intensity requirement, while needing to ensure Sanming City Control the cohesive force that base material is combined with facial ornament, it is emphasized that：The present embodiment by the first PE adhesive films or PP adhesive films 4 with Glass, which is equipped with, between PU flaggies 5, between the 2nd PE rubber powders layer 7 and the 2nd PE adhesive films or PP adhesive films 8 strengthens cloth 9, a side Face ensure that the shaping of sandwich base material, on the other hand improve the local strength of sandwich base material, meet higher-strength vapour The use demand of car roof, while the present embodiment is by rationally setting glass to strengthen the layers of material of cloth 9, and is added by setting to make Qiang Bu, high intensity sandwich base material reasonable process parameter so that glass strengthens cloth 9 while high intensity is met so that high Intensity sandwich base material interlayer has good caking property, it is ensured that the dimensional stability of sandwich base material, while it is away from nothing Spinning the one side of cloth, there is higher cohesive force to combine to form roof of the vehicle with facial ornament, and this sandwich base material has well smooth Degree.
Schematical above that the present invention and embodiments thereof are described, the description does not have restricted, institute in accompanying drawing What is shown is also one of embodiments of the present invention, and actual structure is not limited thereto.So, if the common skill of this area Art personnel are enlightened by it, without departing from the spirit of the invention, are designed and the technical scheme without creative Similar frame mode and embodiment, all should belong to protection scope of the present invention.
