Problems solved by technology

However, the existing coatings on the market have good composite fastness when combined with dry composite glue, but they have no fastness when combined with water-based glue. The tape is separated from the paper after being pulled, and the fastness is poor. It directly restricts the promotion and use of water-based glue. Therefore, there is an urgent need for an OPP aluminized film back coating with good fastness to water-based glue in the market to promote the development of the entire industry.

Embodiment 1-5

[0031] Examples 1-5 provide an OPP aluminized film back coating with good fastness to water-based glue, and its components and parts by weight are shown in Table 1.

[0032] Its preparation method is specifically:

[0033] (1) Put all the solvents into the reaction kettle, and heat to 30-60°C for stirring;

[0034] (2) Keep stirring and put the resins and additives into the reaction kettle in turn, and stir for 0.5 to 2.5 hours;

[0035] (3) Measure the solid content and adjust to the theoretical value;

[0036] (4) Slowly stir again for 0.5-2.5 hours, cool down, weigh and pack.

Abstract

The invention relates OPP (oriented polypropylene) aluminum laminated film back-coating paint with good fastness to waterborne glue and a preparation method thereof. The paint is prepared from the following components in parts by weight: 5 to 10 parts of polyacrylate resin, 1 to 5 parts of polyol resin, 5 to 10 parts of polyurethane resin, 5 to 15 parts of vinisol, 1 to 5 parts of aldehyde ketone resin, 0.1 to 2 parts of auxiliary and 68 to 84 parts of solvent. The OPP aluminum laminated film back-coating paint has the following beneficial effects that the OPP aluminum laminated film back-coating paint has good fastness with the waterborne glue, and the pulling and tearing fastness of an adhesive tape after compounding is excellent; the application scope is wide, the use is convenient and the production cost of an enterprise is reduced; when the paint is used by matching with the waterborne glue, the VOC (volatile organic compound) residue is low.

Description

technical field [0001] The invention relates to the technical field of backing paper for cigarettes, in particular to an OPP aluminized film back coating with good fastness to water-based glue and a preparation method thereof. Background technique [0002] Oriented stretch polypropylene (OPP) transfer film has been widely used in the production of interlining paper for cigarettes. For example, polypropylene film is used as the base film, coated with laser transfer coating and molded to display laser information. The molded OPP film is coated with aluminum and then Apply backcoat and laminate to backing paper. At present, dry compound glue is mostly used for compounding in China, and the dry compound glue uses two components of the main agent and the curing agent. After compounding, it needs a certain curing time and the operation is complicated. However, water-based glue has fast drying speed, low price, no curing, and almost zero VOC emissions, which is the future developm...
