Abstract
The utility model discloses a PVC protective film, which consists of a pressure-sensitive adhesive layer, a PVC substrate layer, a printed layer and an anti-sticking layer, the pressure-sensitive adhesive layer, the PVC substrate layer, the printed layer and the anti-sticking layer are combined sequentially from the bottom up, wherein the pressure-sensitive adhesive layer is directly spread on one surface of the PVC substrate layer. Compared with the conventional protective films, the PVC protective film does not have a priming coating layer, consequently, the structure of the protective film is simpler, the production process can be simplified, and the production cost and the use cost can be reduced.
Description
Technical field
The utility model relates to a kind of protecting materials, and more particularly, the utility model relates to a kind of PVC protective membrane.
Background technology
Protective membrane is a kind of protecting materials that is used to protect the commodity surface; It is attached to the surface of commodity such as aluminium section bar, mat glass; The surface that is usually used in manufacturing, transportation, secondary processing, storage and use the protection commodity is avoided commodity to be polluted or is scratched.Through using protective membrane, not only can improve product visual appearance, make things convenient for materials processed, also can improve the utilization ratio of material simultaneously, reduce production costs.Protective membrane commonly used mainly contains two kinds of PE protective membrane and PVC protective membranes, and wherein, than the PE protective membrane, the docile property of PVC protective membrane, versatility are good, good weatherability.At present, known PVC protective membrane is mostly by PVC base material film, printed layers; Adherent layer; Undercoat and pressure-sensitive adhesive layer are formed, and wherein employed pressure-sensitive adhesive layer be rubber pressure-sensitive adhesive mostly, owing to migration of plasticizer in the difference of the surface energy of itself and base material and the base material; Need be coated with one deck silane coupling agent earlier at substrate surface, form undercoat.Therefore production technique is complicated, and use cost is higher.
The utility model content
The purpose of the utility model is to the above technical problem that will solve, provide a kind of simple in structure, can simplify production process, reduce the PVC protective membrane of production use cost.
The purpose of the utility model realizes through following technical scheme:
A kind of PVC protective membrane; Comprise pressure-sensitive adhesive layer, PVC substrate layer, printed layers and adherent layer; Said pressure-sensitive adhesive layer, PVC substrate layer, printed layers and adherent layer are compound successively from the bottom to top, and wherein, said pressure-sensitive adhesive layer is directly coated on the surface of said PVC substrate layer.
As a preferred embodiment of the utility model, said pressure-sensitive adhesive layer is the water-and acrylate pressure-sensitive adhesive layer.
As another preferred embodiment of the utility model, said printed layers is a polyacrylate polymers.
The described protective membrane of the utility model has reduced undercoat one time under the prerequisite of guaranteeing the quality product moment-less influence, thereby has reduced coating process one time.Therefore, compared with prior art, the utility model has been simplified product structure and production technique, greatly reduces to produce and use cost.
Description of drawings
Fig. 1 is the cross section structure synoptic diagram of the said PVC protective membrane of the utility model.
Embodiment
As shown in Figure 1; The described PVC protective membrane of the utility model is made up of pressure-sensitive adhesive layer 4, PVC substrate layer 1, printed layers 2 and adherent layer 3; Said pressure-sensitive adhesive layer 4, PVC substrate layer 1, printed layers 2 and adherent layer 3 are compound successively from top to bottom; Wherein, said pressure-sensitive adhesive layer 4 is directly coated on the surface of said PVC substrate layer 1.
In the described protective membrane of the utility model, said printed layers 2 is preferably by organic-silicon-modified polyacrylate polymers.Said adherent layer 3 is preferably the mixture of Z 150PH and silicone oil.Said pressure-sensitive adhesive layer 4 is preferably the water-and acrylate pressure-sensitive adhesive layer.According to prior art, the preparation material of the above each composite bed all can obtain through the commercial channel.
The making method of the described protective membrane of the utility model is following: printed layers 2 is uniformly coated on the surface of PVC substrate layer 1; On said printed layers 2, coat adherent layer 3 then, again pressure-sensitive adhesive layer 4 is uniformly coated on another surface of said PVC substrate layer 1.At last, the protective membrane volume is processed in the rolling of gained finished product.
The utility model is not limited to above-mentioned embodiment; If spirit and scope that the various changes or the modification of the utility model do not broken away from the utility model; If these are changed and modification belongs within the claim and equivalent technologies scope of the utility model, then the utility model also is intended to comprise these changes and modification.
Claims (3)
1. PVC protective membrane; Comprise pressure-sensitive adhesive layer, PVC substrate layer, printed layers and adherent layer; Said pressure-sensitive adhesive layer, PVC substrate layer, printed layers and adherent layer are compound successively from the bottom to top, it is characterized in that: said pressure-sensitive adhesive layer is directly coated on the surface of said PVC substrate layer.
2. PVC protective membrane according to claim 1 is characterized in that: said pressure-sensitive adhesive layer is the water-and acrylate pressure-sensitive adhesive layer.
