Energy-saving and environment-friendly solid wood door UV roller coating method

Abstract

The invention discloses an energy-saving and environment-friendly solid wood door UV roller coating method. The method comprises the following steps that A, a plain plank is sanded; B, waterborne coloring is performed, specifically, waterborne colorant roller coating is performed on the door plank by adopting a double-roller coloring roller coating machine; C, waterborne base coat drying is performed; D, UV putty roller coating is performed, specifically, putty roller coating is performed for the first time, semi-curing is performed by adopting LED lamps, then putty roller coating is performedfor the second time, and full curing is performed by adopting the LED lamps; E, UV undercoat roller coating is performed, specifically, undercoat roller coating is performed for the first time, curing is performed by adopting the LED lamps, undercoat roller coating is performed for the second time, and curing is performed by adopting the LED lamps; and F, UV finishing coat roller coating is performed, specifically, finishing coat roller coating is performed for the first time for embellishing, then finishing coat roller coating is performed for the second time, curing is performed by adoptingthe LED lamps, finally, finishing coat roller coating is performed for the third time, and curing is performed by adopting the LED lamps. According to the energy-saving and environment-friendly solidwood door UV roller coating method, by optimizing a UV roller coating process and adopting a waterborne colorant, the environment-friendly property of products can be greatly improved; and by performing curing treatment by adopting the LED lamps and the like, the product production energy consumption can be reduced easily.

Description

technical field [0001] The invention relates to a solid wood door manufacturing process, in particular to a solid wood door UV roller coating method. Background technique [0002] Ultraviolet light (UV) curing is to use the photosensitivity of the photoinitiator to form excited ecological molecules under the irradiation of ultraviolet light, decompose into free radicals or ions, and make unsaturated organic compounds undergo chemical reactions such as polymerization, grafting, and crosslinking. To achieve the purpose of curing, this technology is widely used in the coating process of wooden doors because of its remarkable advantages such as fast drying speed, low operating cost, and high product quality. [0003] With the development of technology for many years, the UV roller coating process has become relatively mature, but the current UV roller coating process for solid wood doors still generally has the following shortcomings: First, the environmental protection needs to...
