Embodiment 1

[0026] ① Take 50g of stearic acid (octadecanoic acid) and 4.5g of nonylphenol polyoxyethylene ether (OP-10), put them into a 250ml three-necked flask, heat to 70-80℃ and melt to obtain the oil phase;

[0027] ② Slowly add 100g of pure water preheated to 80°C to the above oil phase under stirring. After the dropwise addition, heat to 85°C and keep stirring for 30 minutes to obtain an emulsion, stir and cool to room temperature to obtain The hot-melt concealed car line paste of the present invention. This car line paste can form clear and uniform white lines on the surface of the material through screen printing, and it is not easy to drop powder. The white positioning line is completely hidden at 75°C for 10 minutes, and no imprint can be seen.

Embodiment 2

[0029] ①Take 150g of palmitic acid (hexadecanoic acid) and 12g of polyoxyethylene lauryl ether, put them into a 500ml three-neck flask, heat to 70-75°C and melt to obtain the oil phase;

[0030] ② Slowly add 280g of pure water preheated to 75°C to the above oil phase under stirring. After the dropwise addition, heat to 80°C and keep stirring for 30 minutes to obtain an emulsion. Stir and cool to room temperature to obtain The hot-melt concealed car line paste of the present invention. This car line paste can form clear and uniform white lines on the surface of the material through screen printing, and it is not easy to drop powder. The white positioning line is completely hidden at 70°C for 10 minutes, and no imprint can be seen.

Embodiment 3

[0032] ①Take 30g of stearic acid, 20g of palmitic acid, and 4.0g of Tween-60 (polyoxyethylene ether of sorbitan stearate monoester), add them into a 250ml three-necked flask, heat to 72-78°C and melt to obtain the oil phase ;

[0033] ② Slowly add 95g of pure water preheated to 75°C to the above oil phase under stirring. After the dropwise addition is completed, heat to 80°C and keep stirring for 30 minutes to obtain an emulsified body. Stir and cool to room temperature to obtain The hot-melt concealed car line paste of the present invention. This car line paste can form clear and uniform white lines on the surface of the material through screen printing, and it is not easy to drop powder. The white positioning line is kept at 73°C for 10 minutes and then it is completely hidden, and no imprint can be seen.

Abstract

The invention relates to a hot-melting veiled car line paste and a preparation method thereof. The car line paste is composed of 100 parts of high-saturated fatty acid, 5 to 10 parts of polyoxyethylene-type nonionic surfactant and 180 to 220 parts of purified water. The preparation method comprises the following steps of: 1) putting the high-saturated fatty acid and the polyoxyethylene-type nonionic surfactant into a container; heating to the temperature of 70 to 80 DEG C and melting, thereby preparing an oil phase; 2) slowly dropwise adding the purified water preheated to the temperature of 70 to 80 DRG C into the oil phase in a stirring manner; after dropwise adding, heating to the temperature of 78 to 85 DRG C; preserving heat and stirring for 30 minutes, thereby obtaining an emulsifying body; and stirring and cooling to the room temperature, thereby obtaining the hot-melting veiled car line paste. By adopting the screen plate printing, a white positioning line formed on the surface of a fabric material is clear, long in retention time and free of blocking a screen plate during the printing process. The positioning line can be automatically molten to disappear after the fabric material is shaped in a processing manner, and cannot generate any residual trace. The raw materials and the product provided by the invention are safe, environment-friendly and free of toxic effect to a human body.

Description

technical field [0001] The invention relates to the field of printing materials, in particular to a hot-melt concealed thread paste used in the production of shoes, clothing, bags and leather and a preparation method thereof. Background technique [0002] In the production process of shoes, clothing, luggage and leather, it is necessary to sew different shapes or sizes of leather, woven fabrics and velvet into designed patterns. Thread paste is such a fine chemical product, which is printed on the surface of raw materials such as leather, woven cloth, and velvet in the production process of shoes, clothing, bags, and leather by screen printing to form lines, which are used as sewing marking lines for positioning. It is used for cutting, sewing, and sewing along the line to ensure that the shape will not be skewed or deviated. Lin Qingfu (CN102702843A) discloses a water-based thread paste and a preparation method thereof, which is prepared by mixing powdery bentonite and cal...
