Problems solved by technology

[0002] There are many kinds of fragile materials, such as fragile paper and fragile film. Fragile materials are widely used in the label industry. They can be used as carrier materials for anti-counterfeiting labels. The label should be damaged. There are many ways to make fragile materials. One is fragile paper. The strength of the paper itself is not high. The fragile paper will further reduce the strength of the paper. The solvent resistance and light resistance of fragile paper are not high. , a kind of fragile film by extrusion method, which adopts multi-layer co-extrusion method to reduce the strength of the core material, and at the same time add more fillers to change the strength of the material itself. The cost of this production method is relatively high, due to If too much filler is added, it is easy to break the membrane during the process of pulling the membrane, which requires high equipment. One is the electric shock method: such as BOPP, PET, etc., which use the electric spar...

Abstract

The invention discloses a formula of a fragile film and a manufacturing method thereof, and the formula of the fragile film comprises the following raw materials in parts by weight: 100 parts of water-based resin, 5-60 parts of color paste, 1-10 parts of a thickening agent, 0.1-10 parts of a leveling agent, 1-10 parts of a defoaming agent and 1-20 parts of a curing agent. The color paste is white, the solid content is 30-70%, the filler is one or a mixture of more of mica powder, talcum powder, kaolin, titanium dioxide and calcium carbonate, and the particle size d50 is 10-60 [mu] m. By adopting the water-based resin and a certain amount of the auxiliary agent, the water-based resin composite material can be broken under relatively high tensile strength, has solvent resistance and high-temperature yellowing resistance, can well absorb laser with the wavelength of 1064nm, improves the environmental protection property and meets the use requirements.
