Problems solved by technology

At present, there are still some problems in the application process of PE protective film to varying degrees. For example, in the process of producing PE protective film, due to the influence of the performance of PE film itself, the cut surface is not smooth, which makes the edge of the film produce obvious burrs, and there are It may cause new scratches on the protected products when the film is applied, reducing the production quality and market competitiveness of the company's products

Embodiment 1

[0022] The PE protective film material for automobiles prepared in this example has the following components in parts by mass: 100 parts of LDPE / LLDPE (9:1), 0 part of filler, and 0 part of plasticizer.

[0023] The preparation method is as follows:

[0024] First, LDPE and LLDPE are pre-mixed in a high-speed mixer for 5 minutes in proportion, and then the mixed raw materials are put into a twin-screw extruder, and melted and extruded at 170°C to pelletize. The preparation steps of the PE protective film are: put the modified PE pellets into the twin-screw extruder, melt and mix them at 170°C, stretch them into a film, and then apply the cross-linked acrylic resin adhesive to the PE protective film. On one side of the membrane, the protective membrane is then passed through a longer air heating channel (100°C) to ensure that the water or solvent is evaporated. Then directly rewind and cut.

[0025] The samples obtained by granulation in Example 1 were prepared for tensile st...

Embodiment 2

[0027] The PE protective film material for automobiles prepared in this example has the following components in parts by mass: 100 parts of LDPE / LLDPE (8:2), 0 part of filler, and 0 part of plasticizer.

[0028] The preparation method is as follows:

[0029] First, LDPE and LLDPE are pre-mixed in a high-speed mixer for 10 minutes according to the proportion, and then the mixed raw materials are put into a twin-screw extruder, and melted and extruded at 150°C for granulation. The preparation steps of the PE protective film are: put the modified PE pellets into the twin-screw extruder, melt and mix them at 170°C, stretch them into a film, and then apply the cross-linked acrylic resin adhesive to the PE protective film. On one side of the membrane, the protective membrane is then passed through a longer air heating channel (100°C) to ensure that the water or solvent is evaporated. Then directly rewind and cut.

Embodiment 3

[0032] The PE protective film material for automobiles prepared in this example has the following components in parts by mass: 100 parts of LDPE / LLDPE (6:4), 0 part of filler, and 0 part of plasticizer.

[0033] The preparation method is as follows:

[0034] Weigh each raw material in proportion, pre-mix LDPE and LLDPE in a high-speed mixer for 5 minutes in proportion, then put the mixed raw materials into a twin-screw extruder, melt and extrude at 130°C for granulation. The preparation steps of the PE protective film are: put the modified PE pellets into the twin-screw extruder, melt and mix them at 170°C, stretch them into a film, and then apply the cross-linked acrylic resin adhesive to the PE protective film. On one side of the membrane, the protective membrane is then passed through a longer air heating channel (100°C) to ensure that the water or solvent is evaporated. Then directly rewind and cut.

Abstract

The invention relates to a PE protective film material for automobiles and a preparation method thereof. According to parts by mass, the components include: 100 parts of polyethylene PE, 10-30 parts of filler, and 1-5 parts of plasticizer. The preparation method includes: (1) weighing each raw material in proportion, melt extruding and granulating; (2) putting PE pellets into a twin-screw extruder, melting and mixing at 160-170°C, and stretching to form a film , and then apply the cross-linked acrylic resin adhesive to one side of the PE protective film, then pass the protective film through the air heating channel, and finally rewind and cut it. The invention significantly improves the tensile strength, reduces the toughness to a certain extent, further eliminates the phenomenon of burrs on the edge of the film caused by the uneven cutting surface, and effectively reduces the manufacturing cost of PE protective film products for automobiles, and has good application prospects.

Description

technical field [0001] The invention belongs to the field of PE protective films, in particular to a PE protective film material for automobiles and a preparation method thereof. Background technique [0002] Polyethylene (PE) is the simplest polymer organic compound and the most widely used polymer material in the world today. PE protective film is based on special polyethylene (PE) plastic film, which can be used on the surface of various trim materials of automobiles. Its biggest advantage is that the protected trim materials are not affected by Pollution, corrosion, scratches, and protect the original smooth and shiny surface. For this reason, domestic and foreign high-end auto manufacturers' spare parts processing companies widely use PE protective films in the manufacturing process to protect products from pollution, corrosion and scratches, thereby improving the production quality and market competitiveness of their products. [0003] With the development of science...
