Description

Technical Field

[0001] The invention relates to the technical field of coating, and in particular to a coating material for viewing. Background Art

[0002] In the early days of product packaging, in order to prevent products from being contaminated, scratched and physically damaged by the external environment, simple paper packaging or plastic film packaging gradually emerged. Summary of the invention

[0003] One of the purposes of the present invention is to provide a coating material for viewing.

[0004] To achieve the above purpose, the technical solution adopted by the present invention is: a film material for viewing is synthesized by mixing the following raw materials in the following proportions: 1-10 parts of PVDF material, 1-10 parts of PTFE material, and 1-10 parts of ETFE material. Preferably, the preparation method comprises the following steps: Step 1: Melting the materials: 1-10 parts of PVDF material, 1-10 parts of PTFE material, and 1-10 parts of ETFE material are heated to melt the materials; Step 2: Mix and stir, slowly mix the dissolved PVDF material, PTFE material and ETFE material according to the proportion, and ensure that the molten materials are mixed evenly by stirring; Step 3: Film forming: the mixed molten material is extruded or calendered into a film through equipment.

[0005] Preferably, in step 1, the heating temperature needs to be determined according to the melting point and thermal stability of different materials.

[0006] Preferably, in the step 2, the stirring speed and time are controlled according to the melting state.

[0007] Preferably, in step three, a coating is formed by cooling and fixing.

[0008] Compared with the prior art, the present invention has the following beneficial effects:

[0009] (1) The present invention integrates PVDF material, PTFE material and ETFE material. PVDF material can maintain stable performance in a wide temperature range, and its glass transition temperature and melting point are relatively high. PTFE material has extremely high chemical stability and is almost not corroded by any chemical substances. It can withstand the erosion of strong acids (such as sulfuric acid, hydrochloric acid), strong bases (such as sodium hydroxide) and various organic solvents (such as benzene, acetone). At the same time, PTFE material can maintain stable performance in a wide temperature range. It can withstand higher temperatures and can still be used normally at around 260°C; at the same time, it will not become brittle at extremely low temperatures (about -200°C). ETFE material has strong resistance to ultraviolet radiation and will not show obvious aging phenomena such as yellowing and brittleness when exposed outdoors for a long time. In application scenarios such as building facades and greenhouses, ETFE material can maintain good appearance and performance for a long time, providing lasting protection and beautiful visual effects for buildings.
