Effect of wax powder on wood grain transfer of aluminum profile

Various types of low molecular weight and low melting point wax powder are often added to the conventional powder coating formula of aluminum profile to make the coating have good scratch, anti caking, wear resistance, extinction, degassing and texture effect However, referring to the relevant materials of thermal sublimation transfer powder coating for aluminum profile, it is found that many people are skeptical of adding wax powder to the formula, and think that the powder coating is in thermal transfer after adding wax powder There will be "paper sticking" phenomenon during printing However, in the process of experiment, we found that the wax powder has a positive effect on the depapering of the powder coating for aluminum profile heat transfer printing [upload = JPG] / crowd / UploadFile / July 2014 / July 201473020455293098 JPG [/ upload] group A did not add wax powder, group B added 0.3% wax powder The hardness of group B is higher than that of group A after pulverizing and spraying, and the paper printing of group AB is less after vacuum transfer, and the transfer effect of group B is better than that of group A Group C did not add wax powder, group D added 0.2% wax powder, the hardness of group D was higher than that of group C after pulverizing and spraying plate, the marks of group CD were less after vacuum transfer, and the transfer effect of group D was better than that of group C Through experiments, we found that the proper addition of wax powder can increase the hardness of the coating, improve the coating leveling, and help to improve the "stick paper" and the residual marks on the coating surface after transfer printing However, some wax powder migration to the surface after addition is not good for transfer printing, some extinction wax powder can promote the coating leveling, but has a great impact on the transfer printing effect.
