Abstract

The invention provides an in-situ reinforced wooden product UV-3D printing coating and a preparation method thereof. The coating comprises a printing raw material and modified nanocellulose. The preparation method of the coating comprises the following steps of mixing a reinforcement, a catalyst and the printing raw material according to a certain proportion to prepare printing composite resin capable of being used for the wooden product UV-3D printing coating; and introducing the printing composite resin into a UV-3D printer, and making an in-situ polymerization reaction on the modified nanocellulose and the printing raw material in the UV-3D printing process by regulating and controlling printing parameters such as printer precision, speed and UV wavelength, so that the in-situ enhancedUV-3D printing coating is prepared on the surface of a wooden product. The problems that in the prior art, a UV-3D printing coating is low in strength, weak in interface bonding and the like are solved. According to the in-situ reinforced wooden product UV-3D printing coating, the strength of the printing coating can be improved through the high-rigidity and high-strength nanocellulose, and meanwhile, the printing composite resin is subjected to the in-situ polymerization reaction in the printing process, so that the interface bonding of the printing coating and the wooden product is also effectively enhanced.

Description

technical field [0001] The invention relates to a UV-3D printing coating and a preparation method thereof, in particular to an in-situ enhanced wood product UV-3D printing coating and a preparation method thereof, belonging to the field of material processing. Background technique [0002] The surface decorative coatings of wood products established by traditional processes (such as painting and printing) can effectively improve the appearance quality and functionality of wood products, but these methods still have many problems such as complex processes, high finishing requirements, and the release of harmful volatiles. With the advancement of science and technology and the enhancement of people's awareness of environmental protection, the application of new technologies (such as 3D printing technology) in the coating of wood products has attracted widespread attention, and has great application prospects in the fields of surface decoration and functionalization of wood prod...
