Problems solved by technology

However, due to the use of transparent hardened film, the touch is hard and the hand feel is not good, and the hardened film is not impact-resistant, cannot provide a good cushioning effect, and is easy to damage
[0003] Silicone materials and polyurethane materials are widely used in electronic products such as mobile phones and tablet computers. They are often used as protective covers, which have the functions of preventing product appearance damage and enhancing drop and impact resistance. However, traditional protective covers of this type have the following disadvantages: 1. Silicone materials and polyurethane materials are directly injected, and various patterns and logos cannot be printed. The color is single and unfashionable; 2. The surface is easy to stick to dust, which affects the appearance of the product, and bacteria and fungi are easy to adhere and accumulate on the surface; 3. Too soft , low stiffness, poor hand feeling

Embodiment 1

[0021] Such as figure 1 As shown, the transparent film layer 102 of the PET film with a thickness of 0.15mm and a width of 1000mm is coated with an addition molding silicone material as the glue layer 104. The other composition of the glue layer is as follows: 50-60 parts of vinyl silicone rubber, 20 -30 parts of nano silicon dioxide, 10-20 parts of silicone oil, 1-5 parts of conductive ionic liquid, 0.5-2.5 parts of platinum catalyst, 0.5-2.5 parts of hydrogen-containing silicone oil, 1-3 parts of trifluoroacetic acid . The coating thickness is 0.1mm, and the coated PET film undergoes cross-linking and curing reaction at high temperature and then is wound to obtain the final molding film material.

Embodiment 2

[0023] Such as figure 2 As shown, the transparent film layer 102 of PET film with a thickness of 0.15mm and a width of 1000mm is coated with a water-based polyurethane coating on both sides. The coating thickness is 1μm. This coating can be used as both the ink easy adhesion layer 101 and the adhesive layer Easy-adhesive layer 103, on either side of the PET film with ink and adhesive layer. The easy-adhesive layer is coated with an addition-molded silicone material as the adhesive layer 104. The other composition of the adhesive layer is as follows: 50-60 parts of vinyl silicone rubber, 20 -30 parts of nano silicon dioxide, 10-20 parts of silicone oil, 1-5 parts of conductive ionic liquid, 0.5-2.5 parts of platinum catalyst, 0.5-2.5 parts of hydrogen-containing silicone oil, 1-3 parts of trifluoroacetic acid . The coating thickness is 0.1mm, and the coated PET film undergoes cross-linking and curing reaction at high temperature and then is wound to obtain the final forming fil...

Embodiment 3

[0025] Such as figure 2 As shown, the transparent film layer 102 of PC film with a thickness of 10μm and a width of 1000mm is coated with water-based polyester paint on one side, and the coating thickness is 0.1μm. This coating serves as the ink easy adhesion layer 101, and the other side is coated with modified Organosilicon paint, the thickness of the coating is 0.2μm. This coating is used as the easy-adhesive layer 103, and the side with the easy-adhesive layer is coated with peroxide-initiated organic silicon material as the adhesive layer 104. Other adhesive layers The composition is as follows: 50-60 parts of methyl silicone rubber, 20-30 parts of nano silica, 10-20 parts of silicone oil, 1-5 parts of quaternary ammonium salt, 0.5-2.5 parts of BPO (peroxide Dibenzoyl), 1-3 parts of a mixture of trifluoroacetic acid and titanium dioxide nanoparticles. The coating thickness is 3μm, and the coated PET film is vulcanized at high temperature and then rolled to obtain the fina...

Abstract

The invention discloses a forming film material which comprises a transparent thin film layer (102).A rubber layer (104) is arranged on one face of the transparent thin film layer (102).The invention further discloses application of the forming film material as an inside-die decoration material or to manufacturing a protection sleeve.The forming film material has the advantages of being soft, elastic, excellent in hand feeling, resistant to impact, scratches and abrasion, capable of being printed into various patterns and marks, fashionable and attractive, capable of having an antistatic function, not prone to dust adhesion on surface, lasting and durable in bacterium resistance, capable of being directly attached to glass, stainless steel and other smooth surfaces and convenient to store.

Description

Technical field [0001] The invention relates to the field of chemical materials, in particular to a film material for forming. Background technique [0002] In-mold decoration technology (IMD), also known as coating-free technology, is currently a more popular surface decoration technology. The main structure is a transparent hardened film on the surface, a printed pattern layer in the middle, and a back injection layer. However, due to the use of a transparent hardened film, the touch feel is hard, the hand feel is not good, and the hardened film is not impact resistant, cannot provide a good cushioning effect, and is easily damaged. [0003] Silicone materials and polyurethane materials are widely used in electronic products such as mobile phones and tablet computers. They are often used as protective covers to prevent product appearance damage and enhance anti-fall and impact resistance. However, traditional such protective covers have the following disadvantages: 1. Silicone m...
