Thermal transfer printing production technology for paint-free plate

Abstract

The invention discloses a thermal transfer printing production technology for a paint-free plate. The thermal transfer printing production technology comprises the following steps that raw wood is put in a steaming vat to be steamed at a temperature of 100 DEG C for one week, and oil in the raw wood is steamed out; the raw wood is fragmented to form strip-shaped plates which are 20 to 100mm in width, 10 to 50mm in thickness and unlimited in length; side surfaces of the plates are combed, so that the plates are easy to splice; the side surfaces of the plates, which are used for being spliced, are pasted with glue; the plates are spliced according to required length; the spliced plates are cold-pressed at a temperature of 10 DEG C to 50 DEG C for 0.5 to 26 hours, so as to enable the plates spliced together to form a whole plate; and the procedures of single rolling, single rolling coloring, thermal printing, coloring and the like are conducted. The heat transfer printing production technology for the paint-free plate, which is disclosed by the invention, is simple, is easy to operate and is low in cost, the produced paint-less plate is reliable in quality and has stereoscopic aesthetic feeling, and the service life of the paint-less plate can be prolonged, so the greenness is realized and the environment is protected.

Description

technical field

[0001] The invention relates to wood, in particular to a thermal transfer printing production process of a paint-free board. Background technique

[0002] In the wood market, there are many types of glulam and wood-based panels, and the quality is uneven, such as: melamine boards, decorative boards, ecological boards, multi-layer boards, blockboards, etc. are not moisture-proof, easy to deform, easy to burn, easy to burn, etc. Peeling, uneven board surface, easy delamination, easy fading and other phenomena. The formaldehyde content in wood-based panels is high, which has a fatal carcinogenic effect on the human body and is very harmful to health. Moreover, the current wood-based panels and glulam products can only solve the problems of strong structural strength, no cracking, and high horizontal static and vertical strength, which are far from the real natural texture log panels. The paint-free decorative material has natural texture and clear wood grain, w...
