Abstract
The invention provides a PC composite plate with a hardened surface. A hardened coating is coated on the front of a PC plate; a poly ethylene (PE) protective film is coated on the hardened coating; and the hardened coating is coated on the back of the PC plate, and the PE protective film is coated on the hardened coating. An optical PC plate is used as a substrate, and the surface of the PC plate is hardened by coating the hardened coating on the surface to improve the surface hardness of the PC plate; as the coating is not needed to be subjected to high-temperature treatment during hardening, the surface structure of the PC cannot be influenced and the scattering phenomenon generated due to a nonuniform surface structure is inhibited; and the light transmittance of the adopted PC and the adopted hardened coating reach over 90 percent, so that a product has high surface hardness and the light transmittance is not lost, the application range of the PC is widened, and the PC composite plate is suitable for a touch panel, an illumination panel or a screen protective film and the like.
Description
Technical field
The present invention relates to a kind of incrustation sheet material, relate in particular to a kind of case-hardened PC composite board.
Background technology
Merlon (PC) is daily common a kind of material, because its water white transparency and excellent shock resistance, daily use is at aspects such as laser disc, lens, goggles and headlight.But because the case hardness of Merlon is low; wear no resistance; some Merlon devices that are used for purposes easy to wear need carry out specially treated to the surface; when being used as the screen protection film such as PC; often to improve its case hardness through a high-temperature process; but in high-temperature process, the molecular structure skewness of substrate surface will produce scattering phenomenon, forms usually said " rainbow line " phenomenon.The existence of this rainbow line can influence the light transmittance and the visual effect of product, high-intensity more surperficial cure process, and the difficult more control of rainbow line, visual effect is also just poor more.
Summary of the invention
The objective of the invention is to overcome the deficiency that prior art exists, a kind of case-hardened PC composite board is provided.
Purpose of the present invention is achieved through the following technical solutions:
Case-hardened PC composite board, base material is the PC plate, characteristics are: the front of described PC plate scribbles hardening coat, is covered with the PE diaphragm on the described hardening coat.
Further, above-mentioned case-hardened PC composite board, wherein, the back side of described PC plate scribbles hardening coat, is covered with the PE diaphragm on the described hardening coat.
The substantive distinguishing features of technical solution of the present invention and progressive being mainly reflected in:
Adopt optical grade PC plate as substrate, by the means that are coated with hardening coat on the surface cure process is carried out on PC plate surface, improve the case hardness of PC plate, because coating does not need high-temperature process in hardening process, can not influence the surface texture of PC, suppress because the scattering phenomenon of the inhomogeneous generation of surface texture; In addition; the PC that adopts and the light transmittance of hardening coat can both reach more than 90%; guaranteed not lose light transmittance when product has higher surface hardness, widened the range of application of PC greatly, be widely used in aspects such as contact panel, illumination panel or screen protection film.
Description of drawings
Below in conjunction with accompanying drawing technical solution of the present invention is described further:
Fig. 1: schematic cross-section of the present invention;
The implication of each Reference numeral among the figure:
The 1-PC plate, 2-hardening coat, 3-PE diaphragm, 4-hardening coat, 5-PE diaphragm.
The specific embodiment
As shown in Figure 1, case-hardened PC composite board, base material are polycarbonate plate 1, and PC plate 1 is an optical grade PC material, and light transmittance reaches more than 90%, by extrusion molding, Shooting Technique production; The front of PC plate 1 scribbles hardening coat 2, is covered with PE diaphragm 3 on the hardening coat 2; The back side of PC plate 1 scribbles hardening coat 4, is covered with PE diaphragm 5 on the hardening coat 4.Hardening coat 2 and hardening coat 4 case hardnesses reach more than the 3H/750g, and hardening process does not need high temperature, light transmittance＞90%.
The optical grade PC plate 1 that adopts high transmission rate is as substrate, product thickness is the thinnest can be controlled at below the 1mm, by the means that are coated with hardening coat on the surface cure process is carried out on PC plate surface, improve the case hardness of PC plate greatly, because this coating does not need high-temperature process in hardening process, can not influence the surface texture of PC, suppress because the scattering phenomenon of the inhomogeneous generation of surface texture; In addition, the PC that adopts and the light transmittance of hardening coat can both reach more than 90%, guaranteed not lose when product has higher surface hardness light transmittance, because this coating does not need high-temperature process, can not influence the surface molecular structure of PC, just can not occur so-called rainbow line phenomenon yet, improve product quality, widen the range of application of PC greatly.
The case hardness height of this case-hardened PC composite board can reach more than the 3H/750g, and that hardened surface has is wear-resisting, scratch resistance, solvent-proof characteristic, and the optics penetrance height of this case-hardened PC composite, has splendid ink adhesion simultaneously.Can be applied to contact panel, aspects such as electrical equipment inscription plate, illumination panel or screen protection plate.
It is emphasized that: above only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment did.
Claims (2)
1. case-hardened PC composite board, base material is the PC plate, it is characterized in that: the front of described PC plate scribbles hardening coat, is covered with the PE diaphragm on the described hardening coat.
2. case-hardened PC composite board according to claim 1, it is characterized in that: the back side of described PC plate scribbles hardening coat, is covered with the PE diaphragm on the described hardening coat.
