Thermal transfer printing glue for flat glasses

Abstract

The invention relates to a thermal transfer printing glue for flat glasses, wherein the thermal transfer printing glue is prepared from the following raw materials by weight: 1-50 parts of a chlorinated polyolefin modified resin, 1-50 parts of an epoxy resin, 1-30 parts of cellulose acetate, 0.1-10 parts of a curing agent, 0.1-10 parts of an anti-adhesion aid, and 50-90 parts of an organic solvent. Compared with the thermal transfer printing glue in the prior art, the thermal transfer printing glue of the present invention has the following advantages that the transferred glass can be easily subjected to transfer printing without any chemical treatment, the thermal transfer printing film is initially attached to the glass surface, and then is firmly adhered to the surface of the glass by baking for a certain time at a certain temperature, and the thermal transfer printing glue has characteristics of no discoloration and no cracking during baking, abrasion resistance, water immersion resistance, alcohol resistance and the like.

Description

technical field

[0001] The invention relates to a heat transfer glue, in particular to a heat transfer glue used for flat glass. Background technique

[0002] As a traditional building material, glass has been widely used in the construction and decoration industry, and flat glass is often used in the doors and windows of kitchen and bathroom cabinets in interior decoration. In the past, most of the glass doors and windows of cabinets were decorated with frosting, embossing, carving, inlaying, painting and other techniques. The decoration effect was relatively simple and the decoration process was complicated, which could not meet the requirements of today's society for high-quality decoration and decoration.

[0003] As a relatively new decoration and decoration technology, thermal transfer printing has mature printing technology, rich patterns, bright colors, good reproducibility, simple transfer printing process, and only one-time processing (heating) of a thermal transfe...

Examples

Embodiment 1

[0043] In the batching still, add successively that 15 parts of concentrations are 40% chlorinated polyolefin resin solutions, 20 parts of concentrations are 40% epoxy resin solutions, 10 parts of concentrations are 40% cellulose acetate solutions, 10 parts of epoxy resins and Amino resin mixed with curing agent, 5 parts of fumed silica-based anti-sticking agent, 20 parts of toluene, and 15 parts of methyl ethyl ketone, then started the electric mixer at a speed of 2000 rpm, and stirred for 50 minutes.

[0044] The glass thermal transfer film produced by the glue prepared with this formula, the glass preheating temperature is 60 degrees during transfer printing, the temperature of the rubber roller of the hot stamping machine is 200 degrees, the transfer can be completed with moderate pressure, and the transferred glass is fed into 120 degrees Bake in a high temperature oven for 40 minutes, and the thermal transfer pattern is firmly attached to the glass surface.

Embodiment 2

[0046] Add 30 parts of chlorinated polyolefin resin solutions with a concentration of 20%, 55 parts of epoxy resin solutions with a concentration of 20%, 5 parts of cellulose acetate solutions with a concentration of 20%, and 5 parts of epoxy resin solidification in the batching kettle. agent, 5 parts of fumed silica-based anti-sticking agent, and then start the electric mixer at a speed of 5000 rpm, and stir for 20 minutes.

[0047] The glass thermal transfer film produced with this glue, the glass preheating temperature is 80 degrees during transfer printing, the temperature of the rubber roller of the hot stamping machine is 220 degrees, the transfer can be completed with moderate pressure, and the transferred glass is dried in a 160 degrees oven Bake for 20 minutes, the thermal transfer pattern is firmly attached to the glass surface.

Embodiment 3

[0049] Add 40 parts of toluene, 30 parts of ethyl acetate, 10 parts of chlorinated polyolefin resin, 13 parts of epoxy resin, 1 part of cellulose acetate, 5 parts of epoxy resin curing agent, 1 part of polyethylene wax in batching kettle, Start the electric mixer at a speed of 10,000 rpm and stir for 100 minutes.

[0050] The glass thermal transfer film produced with this glue, the glass preheating temperature is 80 degrees during hot stamping, the temperature of the rubber roller of the hot stamping machine is 230 degrees, and the transfer can be completed with moderate pressure, and the transferred glass is dried in an oven at 170 degrees Bake for 15 minutes, the thermal transfer pattern is firmly attached to the glass surface.
