Description
Technical field
The utility model relates to a kind of high rigidity Thick Composites.
Background technique
Thermoplastic composite material board has wider application range because of the performance high with light weight, intensity, with fortune
For defeated industry, such as new energy lorry, the carriage of light weight and the high thermoplastic composite of intensity can substantially extend new energy
The cruising ability of source lorry and the shock resistance in compartment, the carriage in the compartment of lorry is frequently with thermoplastic composite bee at present
Nest plate, although the modulus of thermoplastic composite cellular board is higher, the characteristics of pore structure loose due to honeycomb core, although can
Panel weight is greatly reduced, but when installing components, such as installation frame, profile, lock, handle metal stress members
When, connect that be easy recess, leak, chinch nail power at stress small, especially for the door-plate in compartment, because its chinch nail power is small, plate is light, thickness
It spends not enough and leads to rigid deficiency, it is therefore, easy because its metalwork falls off, connecting hole expands in frequent folding and collision door-plate
Greatly, the problems such as door-plate is loose.
Chinese patent 201610103703.6 discloses a kind of fiber reinforcement building template and preparation method thereof, and fiber increases
Strong building template includes wooden plate core, and plate core upper and lower surface is connected separately with by continuous fiber reinforced thermoplastic prepreg lamella
The surface layer being compounded to form, is also connected as one by adhesive layer between surface layer and plate core, and adhesive layer is non-woven fabrics, surface layer, plate core
And adhesive layer is complex as a whole by hot pressing, although this kind of fiber reinforcement building template has higher static bending strength, quiet Qu Mo
Amount and light advantage, but because it uses wooden plate core, when applying such template in carrier, because placing it in
In the environment to expose to the sun and rain, it is easy the bending strength, surface layer that cause wood based panel wicking to receive compared with juicy, so as to cause template entirety
Peel strength decline to a great extent, while the chinch nail power for also resulting in template is greatly reduced, and causes metal parts mounted thereto
It is easy to fall off；According to the narration of the preparation method in open file it is found that the preparation of plate core, the preparation of surface layer and plate core and face
The compound of layer is carried out separately, and process is discontinuous, needs artificial intervention to interfere, therefore processing efficiency is low, is not suitable for
Produce in enormous quantities；In addition, therefore, being glued because the compound of surface layer, adhesive layer and plate core is formed using traditional hot pressing direct combination
The connection for connecing layer and surface layer and plate core is only that surface is combined with the surface, and for the slab for needing high rigidity, is made for a long time
With in the process, surface layer and plate core are easy layering and remove, and peel strength is low, and therefore, the preparation method in file disclosed above is not
Suitable for preparing, thickness is larger and the preparation of the higher plate of rigid requirements；Further, since the plate core system in file disclosed above
It needs to use a large amount of adhesives when standby, therefore larger at plate taste, not environmentally.
Utility model content
The utility model be intended to provide a kind of water absorption rate it is low and absorb water after be still able to maintain high bending strength, high-peeling strength and
The high rigidity Thick Composite of high chinch nail power.
A kind of high rigidity Thick Composite described in the utility model, including plate core, the upper and lower surface of plate core connect respectively
Be connected to surface layer, the material of the plate core is the thermoplastic resin of foamed dose of foaming, the surface layer include adhesive media layer,
Strengthening course and protective layer connect strengthening course on a surface of adhesive media layer, connect protective layer on the surface of strengthening course,
The corresponding surface of the another side of adhesive media layer and plate core is complex as a whole, the strengthening course is increased by single-layer or multi-layer continuous fiber
Heat-flash plastic resin prepreg lamella is laid with to be formed, and the material of the adhesive media layer is porous air pervious material, and the gluing is situated between
Matter level is described in the continuous fiber reinforced thermoplastic resin prepreg lamella of strengthening course being partially submerged into strengthening course on one side
Adhesive media level is partially submerged into plate core on one side to plate core.
A kind of high rigidity Thick Composite described in the utility model, because using the thermoplastic resin system of foaming
Make plate core, water absorption rate is very low, therefore, so that slab is kept lightweight, moreover it is possible to have this hard solid thick plate
Higher rigidity, to guarantee the connection of metal parts, it is ensured that have higher chinch nail power, avoid falling off for metal parts, in addition, logical
Hard solid slab core is crossed in conjunction with the surface layer containing continuous fiber reinforced thermoplastic resin prepreg lamella, still is able to guarantee thick
Plate has high-intensitive, high-modulus and high shock resistance；Since thermoplastic resin can be fully infiltrated by porous breathable material
Expect in adhesive media layer obtained, so that it is pre- so that adhesive media layer is partially submerged into obverse continuous fiber reinforced thermoplastic resin
It in leaching tablet layer and is partially submerged into obverse plate core, makes adhesive media layer and continuous fiber reinforced thermoplastic resin prepreg
Intertexture coincident configurations are formed between lamella and plate core, realize the locking of physical mechanical, it is bigger than the intensity against molecular force bonding
Very much, so that the adhesion strength of surface layer and plate core be made to be substantially improved, the peel strength between surface layer and plate core is substantially strengthened, with
The high rigidity of slab cooperates, it is sufficient to surface layer inside and the lamination between surface layer and plate core is effectively avoided, in addition, due to plate
Core has all been abandoned with the production of surface layer and has been connected using adhesive, therefore the smell of sheet forming is small, more environmentally-friendly.
