preparation example Construction

[0022] An embodiment of the present invention provides a method for preparing a composite transfer paper. The composite transfer paper is composed of an aluminum-plated transfer layer, a solvent-free adhesive layer, and a base paper layer arranged in sequence. The preparation method for the composite transfer paper includes the following steps:

[0023] S100, providing base paper layer, solvent-free adhesive and aluminized transfer film;

[0024] S200, using a solvent-free laminating machine to coat the solvent-free adhesive on the surface of the base paper layer, and laminating the aluminized transfer film with the base paper layer coated with the solvent-free adhesive to prepare an uncured composite transfer paper. The base paper layer is tipping paper, the temperature when coating the solvent-free adhesive is 40°C to 80°C, and the coating amount of the solvent-free adhesive is 1.5g / m 2 ~5.5g / m 2 , the compounding speed when the aluminized transfer film is compounded with t...

Embodiment 1

[0046] The base paper layer is 40g / m 2 Tipping paper (double-sided gloss base paper), one-component polyurethane solvent-free adhesive (molecular weight 20000-30000, viscosity 1500mpa·s), polyester aluminized transfer film (peel strength 3N / 15mm). Use a solvent-free laminating machine to coat the solvent-free adhesive on the surface of the base paper layer, and compound the aluminized transfer film with the base paper layer coated with the solvent-free adhesive. The coating temperature is 75°C, and the coating amount 4g / m 2 , compound speed is 225m / min.

[0047] After the compounding is completed, the uncured semi-finished product is taken out from the solvent-free compounding machine, and cured at 50°C for 24 hours or at 30°C for 48 hours to obtain a finished compound transfer paper. In this example, the polyester aluminum-coated transfer film did not peel off during the preparation process, and the finished composite transfer paper was tested for adhesion, and its adhesion...

Embodiment 2

[0049] The base paper layer is 40g / m 2 Tipping paper (double-sided gloss base paper), one-component polyurethane solvent-free adhesive (molecular weight 20000-30000, viscosity 1500mpa·s), polyester aluminized transfer film (peel strength 3N / 15mm). Use a solvent-free laminating machine to coat the solvent-free adhesive on the surface of the base paper layer, and compound the aluminized transfer film with the base paper layer coated with the solvent-free adhesive. The coating temperature is 80°C, and the coating amount 4g / m 2 , compound speed is 225m / min.

[0050] After the compounding is completed, the uncured semi-finished product is taken out from the solvent-free compounding machine, and cured at 50°C for 24 hours or at 30°C for 48 hours to obtain a finished compound transfer paper. In this example, the polyester aluminized transfer film did not peel off during the preparation process, and the finished composite transfer paper was tested for adhesion, and its adhesion leve...

Abstract

The invention relates to a method for preparing a composite transfer paper. The composite transfer paper is composed of an aluminum-plated transfer layer, a solvent-free adhesive layer and a base paper layer arranged in sequence. The preparation method of the composite transfer paper includes the following steps: Provide a base paper layer, a solvent-free adhesive, and an aluminized transfer film; use a solvent-free compound machine to coat the solvent-free adhesive on the surface of the base paper layer, and combine the aluminized transfer film with the The base paper layer coated with the solvent-free adhesive is compounded to obtain an uncured composite transfer paper, the base paper layer is tipping paper, and the temperature when the solvent-free adhesive is coated is 40°C to 80°C , the coating amount of the solvent-free adhesive is 1.5g / m 2 ~5.5g / m 2 , the composite speed is 100m / min-350m / min; and after the uncured composite transfer paper is cured, the base film on the aluminized transfer film is peeled off to obtain the composite transfer paper. The invention also relates to a composite transfer paper. The present invention further relates to a cigarette package product.

Description

technical field [0001] The invention relates to the technical field of cigarette pack auxiliary materials industry, in particular to a composite transfer paper, a preparation method thereof, and a cigarette pack product. Background technique [0002] Composite transfer paper is a kind of composite paper formed by compounding the base paper (paper or cardboard) and the transfer aluminized film through an adhesive, peeling off the base film, and leaving the aluminum layer attached to the base paper. The preparation methods of composite transfer paper include: wet lamination, dry lamination, hot-melt lamination, extrusion lamination and solvent-free lamination, and dry lamination is the main method. The adhesives used in dry compounding are mainly solvent-based, which will not only pollute the environment, but also affect the physical and mental health of production workers, which is not conducive to health and safety standards, and the overall cost is high, so it does not meet...
