Problems solved by technology

The anti-mold and anti-bacterial paper of the prior art, such as coating paraffin on the surface of the paper to prepare a kind of anti-mold paper with strong water resistance, but the use of paraffin makes the separation and degradation of the paper difficult, which does not conform to the concept of green packaging. Therefore, it is necessary to develop coated paper with excellent antifungal and antibacterial effects

Embodiment example 1

[0032] a1, the TiO 2 •nH 2 The molar ratio of O and KOH is 0.4, add an appropriate amount of water, grind, then heat up to 880°C in a muffle furnace, keep warm for 2h, and slowly cool to room temperature to obtain the mesophase K 6 Ti 2 o 7 ;

[0033] a2, then the dispersed intermediate product K 6 Ti 2 o 7 Put it into a small amount of water, let it stand for 1 day, then put the obtained hydrated product into an appropriate amount of water for stirring, continuously add 0.5mol / L hydrochloric acid dropwise, and use a pH meter to control the pH value of the solution to 2.0;

[0034] a3. After the system stabilizes and reaches equilibrium, the intermediate product is filtered out with suction, washed with water until neutral and dried to constant weight to obtain the product titanic acid, and then sintered to 400°C at a speed of 10°C min-1 in a muffle furnace , keep warm for 2h, and slowly cool to room temperature to obtain the mesoporous TiO 2 ;

Abstract

The invention discloses a method for preparing mould-proof antibacterial coating paper. The method comprises the following steps: stirring prepared carboxymethylcellulose, performing ultrasonic treatment for 30 minutes, and uniformly stirring in a 50 DEG C constant-temperature water bath kettle to ensure relatively good fluidity of the mixture for paper base coating; adding CuO-loaded mesoporous TiO2 into carboxymethylcellulose after ultrasonic treatment, uniformly stirring with a high-speed dispersion machine, putting into a 50 DEG C constant-temperature water bath kettle for later use; and determining the coating thickness to be 20-100mu m with a blade, coating paper with a manual coating machine, drying the coated paper in the air, and flattening. The mould-proof antibacterial coating paper has excellent smoothness, bursting strength and tensile strength, and has excellent mould-proof antibacterial performance.

Description

technical field [0001] The invention relates to the technical field of coated paper preparation, in particular to a method for preparing anti-mold and antibacterial coated paper. Background technique [0002] Anti-mold and anti-bacterial coated paper has broad application prospects due to its excellent anti-mold and anti-bacterial properties, such as packaging paper for solid oil foods such as butter and cheese; for long-term storage and transportation of vegetables and fruit fresh-keeping bag paper; anti-bacterial office Special paper; anti-mildew special paper for archives and so on. These antifungal and antibacterial paper products for different purposes are closely related to people's daily life and industrial development, and their application in the packaging field is becoming more and more important. The anti-mold and anti-bacterial paper of the prior art, such as coating paraffin on the surface of the paper to prepare a kind of anti-mold paper with strong water resi...
