Antibacterial formaldehyde-free UV blockboard and preparation technology thereof

Abstract

The invention discloses an antibacterial formaldehyde-free UV blockboard and a preparation technology thereof. The blockboard comprises a base material, an antibacterial layer and a UV curing layer which are sequentially arranged, wherein the antibacterial layer contains formaldehyde removing and bacteria resisting microspheres; each formaldehyde removing and bacteria resisting microsphere comprises a nanometer polymer hollow microsphere of which the center is permeated by water-in-oil droplets; each water-in-oil droplet comprises bamboo vinegar liquid at the outer layer, and a sodium hydroxide water solution at the inner layer; and titanium dioxide aerosol particles are dispersed in the sodium hydroxide water solutions. According to the antibacterial formaldehyde-free UV blockboard, the bamboo vinegar liquid is capable of absorbing volatile harmful gas such as formaldehyde and has spectral sterilizing efficiency to bacteria and fungus; the sodium hydroxide water solutions at the innerlayers are capable of quickly catching formaldehyde; the titanium dioxide aerosol particles are capable of oxidizing formaldehyde molecules caught by the sodium hydroxide water solutions; the water phase and the oil phase are coordinately matched with each other to continuously clean volatile harmful gas such as formaldehyde, and thus harmful bacteria and fungus can be continuously exterminated and inhibited.

Description

technical field [0001] The invention belongs to the technical field of woodworking boards, and in particular relates to a formaldehyde-free UV woodworking board with antibacterial function and a preparation process thereof. Background technique [0002] Veneer is a surface material used for interior decoration or furniture manufacturing. It is made by cutting natural wood or technical wood into thin slices of a certain thickness, sticking them to the surface of plywood, and then hot pressing them. The surface of the veneer, usually with melamine-impregnated film paper, is also adhered to obtain the final finished wood panel. [0003] As people's requirements for the furniture environment are getting higher and higher, my country has accordingly promulgated the industry standard GBT / 28995-2012 "Special Decorative Paper for Wood-Based Panel Facing", which limits the amount of formaldehyde released from melamine-impregnated film paper. However, the amount of formaldehyde emitt...

Problems solved by technology

However, the antibacterial layer in this board uses traditional organic or natural antibacterial agents, and the safety of traditional organic antibacterial agents is still inconclusive, and the antibacterial properties of traditional natural antibacterial agents are poor.
