Embodiment Construction
[0019] In order to understand the technical scheme of the present invention more intuitively and completely, the non-limiting feature descriptions are as follows in conjunction with the accompanying drawings of the present invention:
[0020] Such as figure 1 As shown, the high-toughness tactile film includes a base layer 1, and a layer of release film 3 is adhered to the upper and lower sides of the base layer 1, that is, there is an adhesive layer 2 between the base layer 1 and the release film 3, and the adhesive layer 2 is a silicone pressure-sensitive adhesive. , the outer surfaces of the two release films 3 are coated with a touch-sensitive film layer 4;
[0021] The base layer 1 is composed of the following raw materials in mass ratio: 85% polypropylene, 8% styrene-butadiene copolymer, 2% ethylene-vinyl acetate copolymer, 4% nano-calcium carbonate, and 1% paraffin;
[0022] The tactile film layer 4 is composed of the following raw materials in mass ratio: 80% of water-...

The invention discloses a high-toughness tactile film and a production method thereof. The high-toughness tactile film includes a base layer, a layer of release film is adhered to the upper and lower surfaces of the base layer, and a layer of tactile film layer is coated on the outer surfaces of the two release films; Composed of raw materials with the following mass ratio: 82-88% polypropylene, 6-10% styrene-butadiene copolymer, 1-3% ethylene-vinyl acetate copolymer, 3-5% nano calcium carbonate, 0.5-paraffin wax 1.5%; the tactile film layer is composed of the following raw materials in mass ratio: water-based polyurethane 78-82%, dipropylene glycol methyl ether 2-4%, alcohol ester twelve 2-4%, water 10-14%, polyether polyurethane Thickener 0.3‑0.7%, defoamer 0.3‑0.7%, silicone surfactant 0.5‑1.5%. The thus designed high-toughness tactile film is easy to use and has good toughness.
Description
technical field [0001] The invention relates to the technical field of tactile films, in particular to a high-toughness tactile film and a production method thereof. Background technique [0002] Tactile film is also called soft film. It is a special matte film with special velvet smooth and delicate touch on the surface. It is mainly realized by coating tactile oil on the surface of the film. It can be used for luxury packaging, high-end book packaging, high-end tag etc. When the tactile film is combined with the article, the tactile film is usually laminated to the surface of the article by heating and pressurizing the film process. The film needs to be used in conjunction with the machine, and people cannot directly hold the tactile film to stick the tactile film on the article. , and the current tactile film has poor toughness. Contents of the invention [0003] In view of the above-mentioned defects in the prior art, an object of the present invention is to provide ...
