Problems solved by technology

However, the protective thermal transfer film with conventional UV coating is only suitable for the transfer of flat products, not suitable for the application of curved products.
Because the UV cured UV resin protective layer has only hard and brittle properties and does not have soft properties. During the heat transfer process, it is prone to breakage and cracks when it is bonded to the corners of curved surface products, which affects the quality of the product. Surface Protection

preparation example Construction

[0033] The polyester resin used as the raw material for the preparation of the above UV resin is polyester polyol, and the hydroxyl value ranges from 1% to 2.8%.

[0034] The preparation process conditions of the above-mentioned UV resin capable of "heating and drying" are as follows: add a measured amount of isocyanate into the reaction kettle, add a measured amount of solvent butyl acetate and a polymerization inhibitor p-hydroxyanisole, and then add a measured amount of methacrylic acid Hydroxyethyl ester, the reaction time is 1-5 hours, the reaction temperature is 50-90°C, then add the measured polyester resin, continue the reaction for 1-5 hours, cool down and discharge the material, and add a photosensitizer at an appropriate time, that is, a paintable UV resin that can print "heat drying".

[0035] The heat transfer film of UV resin protection layer of the present invention is first coated with the UV resin layer of the present invention by coating processes such as gra...

Abstract

The invention relates to UV resin. The UV resin has a property of capability of being dried by heating and a property of waiting for UV curing. The UV resin includes, by mass, 40-60% of isocyanate, 25-45% of hydroxyethyl methylacrylate, 30-50% of polyester resin and 0.005-0.01% of a polymerization inhibitor that is 4-methoxyphenol, with the balance being a solvent. A preparing process of the UV resin and applications of the UV resin in preparation of heat transfer membranes waiting for UV curing are also disclosed. Product decoration and surface protection can be finished in one step, thus avoiding a step of spraying of a protective paint layer, saving energy, protecting the environment, and saving labor and materials. Products are beautiful and durable.

Description

technical field [0001] The invention relates to the field of thermal transfer materials and production, in particular to a UV resin that can be "dried by heat", a preparation method of the resin and its application in thermal transfer films. [0002] technical background [0003] With the continuous improvement of people's living needs, the decoration of various materials such as plastic, metal, glass, wood and other materials is becoming more and more important. Only well-decorated products that meet market demand can increase the added value of products and manufacturers can obtain more profit. At the same time, well-decorated products must also have good surface protection properties to make beautiful products durable. [0004] In order to meet the quality requirements of well-decorated and well-protected products, the surface decoration process of the original product manufacturer’s products is transferred to the decorative layer by heat transfer technology, and then spr...
