Coating possessing culicifuge efficacy and printing package material containing coating thereof

Abstract

The invention provides a coating possessing culicifuge efficacy, which is capable of directly coating or transferring on the surface of a printing base material, the coating comprises multicomponent resin and a solvent, the coating also comprises organic fluorescent substance with particle size of 500-700 meshes and reflection wavelength of 585-625 nanometers and a dispersant, wherein the weight percentage of organic fluorescent substance to dispersant is 5-10% and 0.5-2%. According to the coating, by using a principle that the fluorescent substance can absorb the luminous energy, atoms enable spontaneous transition for luminescence as well as the avoidance characteristics of mosquito to the reflection wavelength of the organic fluorescent substance, low-light which can not be seen by naked eyes and can be sensed by mosquito is emitted by the coating after coating process and curing molding, thereby mosquito enables automatic leave, waste generated due to dirt formed on mosquito sticky plate or involvement membrane during the production process can be avoided, cost is reduced, and yield is increased. The invention also provides a printing package material, and is the coating possessing culicifuge efficacy which is directly coated or transferred on the surface of the printing base material.

Description

technical field [0001] The present invention relates to a coating, in particular to a coating that can be directly coated or transferred to the surface of a printing substrate, more particularly to a coating that can be directly coated or transferred to the surface of a printing substrate and has mosquito repellent effect coating. The present invention also provides a printing and packaging material containing the above coating. Background technique [0002] Printed packaging materials refer to packaging materials with specific styles and printed content. At present, for printing and packaging materials used in the fields of food, medicine, cosmetics, etc., in order to improve the printability of the printing substrate (such as paper, film) or increase the decorative effect of the printing substrate, it is generally directly coated on the surface of the printing substrate. Cover a polymer resin layer, or first coat the polymer resin layer on the base film and then transf...

Problems solved by technology

The paper used for cigarette packaging is mainly laser transfer paper and laser composite paper. During the whole process of cigarette pack paper processing and production, the existence of mosquitoes in the production site has a great impact on product quality, which is due to changes in the surrounding environment and seasons , often cause a considerable number of mosquitoes in the production site. These mosquitoes are easy to adhere to the coating and composite pressing rollers during the coating coating and transfer process. During the molding process, it is easy to fly into the plate roller, In the pressing roller, in the process of slitting and cross-cutting, it is easy to be involved in the film roll and paper, all of which can form dirty waste products, which greatly reduces the yield and greatly increases the cost of cigarette pack paper
