Abstract
The utility model relates to a PC/PMMA (polycarbonate/polymethyl methacrylate) composite sheet material. The composite sheet material is a double-layer structure which is integrally combined through mutually permeating surfaces under a hot-melting state. The composite sheet material comprises a PMMA layer and a PC layer, wherein the PMMA layer is a surface anti-scraping layer; the PC layer is a bottom layer and is adhered below the PMMA layer and serves as a supporting layer; the thickness of the composite sheet material is 0.25-1.5 mm; the thickness of the PMMA layer is 0.02-0.1 mm; the thickness of the PC layer is 0.23-1.4 mm; and the hardness of the PMMA layer is 1-3 H. The composite sheet material has better surface strength, impact strength resistance and ageing resistance and can be applied to surface plate materials of view windows and display screens and can meanwhile reach enough hardness without surface coatings, so that the composite sheet material has the advantages of no easy cracking, aging and delaminating of surface and long service life.
Description
Technical field
The utility model relates to the structure that is laminated with sheet material that a kind of double-decker is an one, belongs to technical field of chemical products.
Background technology
Merlon (Polycarbonate) is abbreviated as PC, is a kind of water white indefiniteness thermoplastic.The carbonic ester water white transparency, heat-resisting, shock resistance, fire-retardant, the favorable mechanical performance is all arranged in common serviceability temperature, compare near polymethyl methacrylate with performance, the impact resistance of Merlon is good, the refractive index height, good processability does not need additive just to have UL94V-0 level fire resistance.
PMMA claims lucite or acrylic again, and Chinese formal name used at school is a polymethyl methacrylate, English name: Poly-methyl-Methacrylate.Be the material of asepsis environment-protecting, can be used for producing tableware, cleaners and polishes etc. have good chemical stability and weatherability, and the PMMA resin is difficult for producing sharp-pointed fragment when fragmentation.
Major product in the market is PC coating sclerosis sheet material or PMMA material material, its major function is the dash board material in form, touch-screen and display screen, play transparent, anti-scratch flower effect, but the defective that all exists function to use, the hardened layer of PC coating sclerosis sheet material is to be coated with in the later stage to scrape up, and delamination is aging easily, and the shelf-life is 6-8 month, and its resistance to impact of PMMA sheet plate and bending resistance are poor, and be fragile strong.
The utility model content
The utility model promptly is at existing above-mentioned defective in form and display screen dash board material at present, and a kind of face coat that do not need is provided, and reaches enough hardness simultaneously, the composite sheet of non-friable strong, aging, the delamination in surface, long service life.
Specifically, PC/PMMA composite sheet described in the utility model, it is characterized in that: the double-decker that described composite sheet is combined as a whole for mutual surface seepage under the heat fusing state, comprise PMMA layer and PC layer, wherein, the PMMA layer is the anti-scratch flower layer in surface, and the PC layer is a bottom, be attached at PMMA layer below, be supporting layer.
Described PC/PMMA composite sheet is characterized in that: the thickness of described composite sheet is 0.25mm-1.5mm.
Described PC/PMMA composite sheet is characterized in that: described PMMA layer thickness is 0.02mm-0.1mm.
Described PC/PMMA composite sheet is characterized in that: the PC layer thickness is 0.23mm-1.4mm.
Described PC/PMMA composite sheet is characterized in that: the hardness of described PMMA layer is 1-3H.
Hardness is to weigh performance indications of material soft or hard degree, and the method for hardness test is more, and principle is also inequality, and the hardness number that records is also not exclusively the same with implication.The most frequently used is static load plunging hardness test, i.e. Brinell hardness HB, Rockwell hardness HRA, HRB, HRC, vickers hardness hv, rubber plastic shore hardness HA, the ability that its value representation material surface opposing hard objects of hardness such as HD is pressed into.Lee ' hardness H1, Shore hardness HS then belong to dynamic indentation, and its value is represented the size of metallic elastic work of deformation.Therefore, hardness is not a simple physical quantity, but a kind of integrated performance index of elasticity, plasticity, intensity and the toughness etc. of reflection material.
PC/PMMA composite sheet described in the utility model has following advantage:
1, the base material of two-layer heterogeneity type, under the heat fusing state, the surface is seen through and is combined as a whole mutually, has good counter-bending and resistance to impact, reaches in use shock-resistant, not cracked purpose;
2, this product is a disposal molding, need not apply processing, is widely used in form, display screen touch-screen and mobile phone screen board etc.;
3, this composite sheet has the advantage that case hardness is big, impact strength is big and ageing resistance is strong.
Description of drawings
Accompanying drawing is the structural representation of the utility model embodiment;
Wherein, 1 is that PMMA layer, 2 is the PC layer.
The specific embodiment
Below in conjunction with accompanying drawing PC/PMMA composite sheet described in the utility model is described; purpose is better to understand technology contents described in the utility model for the public; rather than to the restriction of described technology contents; in fact, in the improvement of composite sheet described in the utility model being made with the principle identical or approximate with the utility model all within the utility model technical scheme required for protection.
As shown in the figure, PC/PMMA composite sheet described in the utility model is the mutual double-decker that is combined as a whole of surface seepage under the heat fusing state, comprise PMMA layer 1 and PC layer 2, wherein, PMMA layer 1 is the anti-scratch flower layer in surface, PC layer 2 is a bottom, is attached at PMMA layer 1 below, is supporting layer.
Described PC/PMMA composite sheet, wherein, the thickness of described composite sheet is that the described PMMA layer thickness of 0.25mm-1.5mm is 0.02mm-0.1mm, and the PC layer thickness is 0.23mm-1.4mm, described PC/PMMA composite sheet is characterized in that: the hardness of described PMMA layer is 1-3H.
The manufacture process of PC/PMMA composite sheet of the present utility model is as described below:
Be laminated with production line with bilayer, PC and PMMA respectively are expressed in the sheet material die head with an extruder, under molten condition, be compound to together, control its extrusion capacity by the speed of each extruder, reach the thickness of each layer of control, the PMMA layer thickness is 0.02mm-0.1mm, and the PC layer thickness is 0.23mm-1.4mm.
Effect data of the present utility model relatively contrasts:
| The PC sheet | PC coating sclerosis plate | The PMMA sheet | The PC/PMMA composite sheet | |
| Case hardness | 2B | HB-H | 1-3H | 1-3H |
| Impact strength | 880j/m | 850j/m | 525kj/m | 950j/m |
| Aging | 12 years | 8 months | 12 years | 12 years |
This shows that described composite has better surface strength, impact strength and ageing resistance, can be applied in form and the display screen dash board material, do not need face coat, reach enough hardness simultaneously, non-friable strong, aging, the delamination in surface, long service life.
