Problems solved by technology

Due to the film-forming properties of pigment printing paste, and the pigment particles are wrapped in the film after drying, the resulting product will have a hard hand feel, which is worse than ordinary flocking products; in addition, the limitation of color is also It is relatively large, the number of colors is limited, and a good printing effect cannot be achieved, and the powder spreading process is complicated, and it is difficult to control the spraying amount of hot melt powder evenly. The excess hot melt powder needs to be cleaned up, and then it needs to be dried until it melts , otherwise it may affect the bond fastness of fluff after transfer

preparation example Construction

[0028] The preparation method of thermal transfer adhesive is: add silicone leveling agent and polyether defoamer to water-based polyurethane adhesive in turn, stir evenly, then add PDF thickener to thicken under high-speed stirring To the desired viscosity, filter through a 200-mesh filter and set aside.

[0029] Among them, the water-based polyurethane adhesive is ZS-751 water-based polyurethane adhesive independently developed by Zhang's Flocking Material Equipment (Shenzhen) Co., Ltd., and the silicone leveling agent is YZ-1500 produced by Jiaxing Yuanzhi Chemical Co., Ltd. Silicone leveling agent; polyether defoamer is XAMA-3c polyether defoamer produced by German Bayer Chemical; PDF thickener is a conventional commercially available product.

[0030] The flocking adhesive includes the following raw materials in parts by weight: 45-55 parts of water-based acrylic adhesive, 45-55 parts of deionized water, 0.2-0.6 parts of silicone leveling agent, 0.3-0.3 parts of polyether...

Abstract

A flocking paper for thermal transfer and its production process, a flocking paper for thermal transfer, including flocking base paper, flocking adhesive, fluff layer and thermal transfer adhesive arranged in sequence from bottom to top , the thermal transfer adhesive includes the following raw materials in parts by weight: water-based polyurethane adhesive, silicone leveling agent, polyether defoamer, PDF thickener, thermal transfer adhesive in the present invention The agent is made of water-based polyurethane adhesive mixed with other additives, which has better bonding fastness and can be melted at high temperature. When it is in contact with other carriers under heat and pressure, thermal transfer adhesion The agent softens with the applied temperature, and has fluidity after melting. After the molten body infiltrates the surface of the bonded carrier and cools, the adhesive will be firmly combined with other carriers, replacing the acrylic water glue and heat in the prior art. Melting powder saves the powder spreading process and improves production efficiency.

Description

technical field [0001] The invention belongs to the field of flocking paper, and in particular relates to a flocking paper for heat transfer and a production process thereof. Background technique [0002] Electrostatic flocking technology is a production process that uses the natural characteristics of electric charges. The processed paper obtained by using electrostatic flocking technology is called electrostatic flocking paper. On the surface of the base paper, or only on the specific part of the pattern, after coating the thermoplastic resin, short fibers dyed with various colors are planted in the glued part. When direct current is applied, under the influence of the magnetic field lines, the charge is easier to concentrate on the tip of the short fiber, so that the upright short fiber is adhered to the base paper. The application of flocking paper can overcome the criticism that traditional flocking fine fluff is flying everywhere, and it is difficult to clean the work...
