Production process for primer-free plastic thermal transferred pattern film of bamboo and wood products

Abstract

The invention provides a production process for a primer-free plastic thermal transferred pattern film of bamboo and wood products, which comprises a material preparing stage and a thermal transferring stage, wherein a release agent and a protective agent are diluted and mixed with ethyl ester and medical alcohol; a printing ink is diluted and mixed with the ethyl ester and the medical alcohol; a pet (polyethylene terephthalate) film thermal transferring glue is taken as the glue used in the production process and is diluted and mixed with the ethyl ester and the medical alcohol; and in the thermal transferring stage, the transferred pattern film can be realized, without painting the surface of the bamboo and wood products. The required pattern is firmly transferred according to an original transferring process, thereby greatly lowering the labor and production costs. Besides, the production process has the advantages of energy conservation, environmental protection, high quality, directness, high speed and convenience.

Description

【Technical field】 [0001] The invention relates to a production process of bamboo and wood products, in particular to a production process of thermal transfer printing film of bamboo and wood products. 【Background technique】 [0002] In the traditional thermal transfer printing film production process of bamboo and wood products, release agents, protective agents and inks are usually used as thermal transfer materials. Forming agent, protective agent, and then apply a layer of paint (that is, apply a layer of ink) and glue layer to transfer the pattern. For example, the production process steps of chopsticks thermal transfer printing film are: [0003] 1. Preparation: [0004] 1. Preparation of substrate film (pet); [0005] 2. Preparation of release agent and protective agent (mix the release agent and protective agent with toluene and butanone at a ratio of 1:0.5:1:1 and stir evenly); [0006] 3. Preparation of ink (dilute the ink with 40% toluene and butanone); [0007...

AI Technical Summary

Problems solved by technology

[0023] It can be seen from the above that the traditional production process of thermal transfer printing film for bamboo and wood products requires ink, release agent and protective agent on the surface of bamboo and wood products to transfer the pattern; due to the ink, release agent, The protective agent and ink are diluted with a certain amount of toluene and methyl ethyl ketone, but these materials contain chemical components harmful to the human body and are not environmentally friendly. Manufacturers of bamboo and wood products must coat the surface of bamboo and wood products during the production process. Applying a layer of primer requires many processes; the purchased materials are all produced by different manufacturers, and their properties are unstable. Therefore, the production cost is high, and the quality is prone to falling off of the transfer pattern, which is not wear-resistant and does not meet the health requirements.
