Embodiment 1

[0031] A kind of manufacture method of the cross composite film with TPU film, comprises the following steps:

[0032] 1) Preparation of bottom material: use film blowing equipment to manufacture breathable TPU film, PE film and PP film in sequence;

[0033] 2) One-time lamination: The breathable TPU film, PU adhesive, PP film and PE film are combined in the compound machine, and the PP film and the PE film are arranged on the upper or lower surface of the TPU film at intervals to make a three-layer one-time Composite film, the primary composite film is slit by a rotary slitter, 45︒ angle helical slitting, winding;

[0034] 3) Secondary lamination: take two rolls of the primary composite film and put them into the compound machine after aligning them. Lay transparent nylon mesh in the middle, and ensure that the breathable TPU film of the primary composite film is on the outside, and the two sides of the transparent nylon mesh extend to the outside of the primary composite fil...

Embodiment 2

[0037] A kind of manufacture method of the cross composite film with TPU film, comprises the following steps:

[0038] 1) Preparation of bottom material: use film blowing equipment to manufacture breathable TPU film, PE film and PP film in sequence;

[0039] 2) One-time lamination: The breathable TPU film, PU adhesive and PE film are compounded in the compound machine to form a three-layer primary compound film. Two PE films are arranged on the upper or lower surface of the TPU film at intervals. The primary composite film is slit by a rotary slitter at a 45︒ angle spiral, and wound up;

[0040] 3) Secondary bonding: align the primary composite film and two PP films and put them into the compound machine, lay transparent nylon mesh in the middle, and place the two PP films on the surfaces of the two PE films respectively, and ensure the breathable TPU of the primary composite film The film is on the outside, and the two sides of the transparent nylon mesh extend to the outsid...

Abstract

The invention discloses a cross composite membrane with a TPU membrane and a manufacturing method of the cross composite membrane. The cross composite membrane comprises a first membrane layer, a second membrane layer, a third membrane layer and a fourth membrane layer, wherein the first membrane layer and the fourth membrane layer are breathable TPU membranes respectively; a first adhesive layer is connected between the first membrane layer and the second membrane layer; a second adhesive layer is connected between the second membrane layer and the third membrane layer; a third adhesive layer is connected between the third membrane layer and the fourth membrane layer; a reinforcing mesh extending to the outside is arranged in the first adhesive layer, the second adhesive layer or the third adhesive layer. Through the manner, the cross composite membrane with the TPU membrane and the manufacturing method of the cross composite membrane provided by the invention use the breathable TPU membranes to improve the overall waterproof and breathable performance of the cross composite membrane outside, use the reinforcing mesh to enhance and improve use convenience, and enable the cross composite membrane to have excellent waterproof and breathable performance, high strength, high temperature resistance, acid and alkali resistance and impact resistance by compounding different materials.

Description

technical field [0001] The invention relates to the field of films, in particular to a cross composite film with a TPU film and a manufacturing method thereof. Background technique [0002] The name of TPU is thermoplastic polyurethane elastomer rubber, which is mainly divided into polyester type and polyether type. TPU has a wide range of hardness, wear resistance, oil resistance, high transparency, and good elasticity. It is widely used in daily necessities, sporting goods, toys, decorative materials, etc. It has been widely used in the field, and the composite film made by compounding TPU with other film materials can be widely used in waterproof, medical, outdoor, agricultural, decoration and other fields. [0003] The impact resistance of ordinary TPU composite film is poor, and the strength is difficult to guarantee, which reduces the scope of application and needs to be improved. Contents of the invention [0004] The technical problem mainly solved by the present ...
