Detailed Description
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The invention can be embodied in many other forms without departing from the spirit or essential characteristics thereof, and it should be understood that the invention is not limited to the specific embodiments disclosed below.
Example 1
As shown in fig. 1, the high temperature resistant protective film comprises a first substrate layer 1, a first composite glue layer 2, a high temperature resistant layer 3, a second composite glue layer 4, a second substrate layer 5 and an adhesive layer 6 which are stacked from top to bottom. Wherein, first substrate layer 1 with second substrate layer 5 is formed by the preparation of polyethylene particle blown film, and first compound glue film 2 and second compound glue film 4 are polyacrylate adhesive, and high temperature resistant layer 3 is the polyamide membrane, and adhesive layer 6 is polyacrylate pressure sensitive adhesive.
The thickness of the first substrate layer 1 is 10-20 microns, the thickness of the first composite glue layer 2 is 2-4 microns, the thickness of the high temperature resistant layer 3 is 5-20 microns, the thickness of the second composite glue layer 4 is 2-4 microns, the thickness of the second substrate layer 5 is 10-20 microns, and the thickness of the adhesive layer 6 is 2-10 microns. The thickness of the substrate layer in the embodiment cannot be set to be less than 10 μm, and too low the mechanical property of the film is poor; the thickness of the composite glue layer of the embodiment cannot be lower than 2 μm, otherwise, the impact-resistant layer and the substrate layer cannot be effectively bonded; the thickness of the high temperature resistant layer 3 of this embodiment cannot be less than 5 μm, and if it is less than this size, the high temperature resistance is poor, and the thickness of the adhesive layer 6 of this embodiment is controlled to 2 to 10 μm, and if it is less than this size, the product adhesion is insufficient, and if it exceeds this size, adhesive residue may be caused.
The utility model arranges the first substrate layer 1 on the most surface layer, and the polyethylene material has good water resistance and heat sealing property; the adhesive layer 6 is coated on the second substrate layer 5 because the high temperature resistant layer 3 is inferior in coating performance to the substrate layer, and the adhesive layer 6 is not easily attached to the high temperature resistant layer 3, so that the high temperature resistant layer 3 is bonded between the first and second substrate layers by the composite water gel layer. The utility model discloses a product structural design can improve the high temperature resistance of protection film to prepare a high temperature resistant protection film.
The overall preparation process of the high-temperature-resistant protective film in the embodiment comprises the following steps:
firstly, respectively coating polyacrylate adhesives on one surface of a first substrate layer 1 and one surface of a second substrate layer 5 to form a first composite glue layer 2 and a second composite glue layer 4;
and then placing the high-temperature-resistant layer 3 between the first composite glue layer 2 and the second composite glue layer 4, bonding and compounding, coating an adhesive layer 6 on the other surface of the second substrate layer 5, and rolling to obtain the high-temperature-resistant protective film.
Although the present invention has been described in detail with reference to the embodiments, it will be apparent to those skilled in the art that modifications, equivalents, improvements and the like can be made in the technical solutions of the foregoing embodiments or in some technical features of the foregoing embodiments, but all modifications, equivalents, improvements and the like within the spirit and principle of the present invention are intended to be included in the scope of the present invention.
