Embodiment 1

[0026] An antibacterial superhydrophobic finishing method for slow-release fragrance decorative paper, characterized in that it comprises the following steps, the following raw materials are by weight:

[0027] (1) Copying process of decorative base paper:

[0028] Soak 60 parts of bleached coniferous wood pulp and 40 parts of bleached hardwood pulp in water for 3 hours, use a beater to decompose for 20 minutes, and then start beating. Add 60 parts of titanium dioxide-kaolin composite suspension, 2 parts of wet strength agent and 0.06 parts of retention aid, after sheeting with a standard sheet former, vacuum-dry and balance moisture to obtain decorative base paper;

[0029] Among them, the preparation of titanium dioxide-kaolin composite suspension: dissolve 0.09 parts of dispersant sodium hexametaphosphate in water, add 15 parts of kaolin and 15 parts of titanium dioxide to disperse for 25 minutes, keep the grinding concentration at 45%, and then grind and coat for 30 minute...

Embodiment 2

[0038] An antibacterial superhydrophobic finishing method for slow-release fragrance decorative paper, characterized in that it comprises the following steps, the following raw materials are by weight:

[0039] (1) Copying process of decorative base paper:

[0040] Soak 75 parts of bleached coniferous wood pulp and 50 parts of bleached hardwood pulp in water for 4 hours, use a beater to disperse for 30 minutes, and then start beating. Add 76 parts of titanium dioxide-kaolin composite suspension, 2.5 parts of wet strength agent and 0.08 parts of retention aid, after sheeting with a standard paper former, vacuum-dry and balance moisture to obtain decorative base paper;

Abstract

The invention discloses a slow-release fragrance-type antibacterial super-hydrophobic processing method for decorative paper. The method comprises the steps: immersing bleached softwood pulp and bleached hardwood pulp in water, performing defibering by using a beater, starting beating, adding a titanium dioxide-kaolin composite suspension, a wet strength agent and a retention aid to the pulp, preparing sheets by using a standard paper sheet former, performing vacuum drying and moisture balancing so as to obtain decorative base paper, immersing the obtained decorative base paper in a slow-release fragrance-type antibacterial microcapsule solution, taking the immersed paper out, performing natural drying so as to obtain slow-release fragrance-type antibacterial processed decorative paper, putting hydrophobic-modification cellulose nanoparticles, methyltrimethoxysilane and water in a closed reactor for a reaction, adding the reaction product into tetrahydrofuran, performing ultrasound treatment so as to obtain a super-hydrophobic coating, spraying the coating uniformly to the slow-release fragrance-type antibacterial processed decorative paper by using a spray gun, and performing curing in an oven so as to obtain the slow-release fragrance-type antibacterial super-hydrophobic decorative paper.

Description

technical field [0001] The invention belongs to the field of decorative paper, and in particular relates to an antibacterial and super-hydrophobic finishing method for slow-release fragrance-type decorative paper. Background technique [0002] In my country, decorative base paper has only a production history of more than 40 years, and it is still a new type of industry. As people have increasingly diverse requirements for decoration styles, it is necessary to continuously improve the performance of decorative base paper to meet the requirements of post-processing. However, existing decorative base papers in the market have the disadvantages of poor antibacterial and hydrophobic properties, and cannot have the performance of slow-release fragrance at the same time, so how to obtain a decorative paper with excellent antibacterial and hydrophobic performance of slow-release fragrance is very important. [0003] In the present invention, the essence microencapsulation is to us...
