Description
Technical Field
The invention relates to a high-heat-seal high-light-transmittance glass film, which is mainly used for protecting automobile glass and belongs to the field of application of high polymer materials.
Background
Because the automobile glass is not heat-insulating and ultraviolet-proof, people usually stick a layer of protective film on the glass, and the glass has the performance of heat insulation and the like as a window film protective product. However, the existing adhesive films on the market have various quality and more problems, some films have poor heat sealing property, and some films have poor light transmittance.
In order to solve the technical problems, the invention provides a high-heat-seal high-light-transmittance glass film which not only has good heat seal performance, but also has high light transmittance.
Disclosure of Invention
The invention aims to provide a high-heat-seal high-light-transmittance glass film, which greatly improves the light transmittance of the film through the interaction of nano ceramic and a nucleating agent, and the use of organic silicon resin adhesive not only improves the heat seal property, but also is beneficial to improving the transparency. The glass film has excellent transparency and better heat sealability.
A high-heat-seal high-light-transmittance glass film is prepared from the following components in percentage by weight: 100 parts of polyethylene terephthalate (PET); 3-6 parts of nano ceramic, 10-15 parts of organic silicon resin adhesive, 5-10 parts of adhesive and 1-2 parts of nucleating agent.
The adhesive is phenolic aldehyde-polyvinyl acetal resin.
The grain diameter of the nano ceramic is within the range of 10-50 nm.
The nucleating agent is NC-4 of eastern Japan company.
The preparation method of the high-heat-seal high-light-transmittance glass film comprises the following steps:
(1) weighing the materials in proportion, putting the materials into a high-speed mixer for uniformly mixing for 5 minutes at the mixing speed of 700 plus materials/min at 900 rpm, and then discharging the materials;
(2) the mixed materials are put into a double-screw extruder to extrude sheets, and then four-roll calendering is carried out, wherein the calendering temperature is 180-235 ℃;
(3) when the glass film with high heat seal and high light transmittance is used, the glass film with high heat seal and high light transmittance can be used as a glass film with high heat seal and high light transmittance by removing the release film after the low-viscosity adhesive layer is coated and the release film is pasted.
The invention has the following beneficial effects: the glass film is added with the nano ceramic, and the crystal form is changed under the action of the nucleating agent, so that the light transmittance of the film is greatly improved, and the heat sealability is improved and the transparency is improved due to the use of the organic silicon resin adhesive. The glass film has excellent transparency and better heat sealability. The material used in the invention is easy to obtain, and the selected production process technology is simple and mature, and has practicability and operability.
Detailed Description
Table 1 below prepares glass films for the formulations of examples and comparative examples. The difference between the examples and the comparative examples is that comparative example 1 is made by removing the nanoceramic from the base of example 4; comparative example 2 the silicone resin glue was removed from example 4.
In the examples, the adhesive is a phenolic-polyvinyl acetal resin; the grain size of the nano ceramic is within the range of 10-50 nm; the nucleating agent is NC-4 of eastern Japan company.
Examples and comparative examples of the present invention are shown in Table 1.
TABLE 1
The preparation method of the high heat-seal high-transmittance glass film in the above embodiment is as follows:

(2) The mixed materials are put into a double-screw extruder to extrude sheets, and then four-roll calendering is carried out, wherein the calendering temperature is 200-215 ℃.
(3) When the glass film with high heat seal and high light transmittance is used, the glass film with high heat seal and high light transmittance can be used as a glass film with high heat seal and high light transmittance by removing the release film after the low-viscosity adhesive layer is coated and the release film is pasted.
The results of the performance tests of the examples and comparative examples are shown in Table 2 below.
TABLE 2
