Problems solved by technology

At present, most synthetic leather surfaces on the market are difficult to clean with ordinary household cleaners after being stained with stains. In order to clean the surface stains, people will repeatedly scrub with strong detergents. It is also damaged, ranging from changes in haze, to severe damage to the surface layer of synthetic leather, resulting in the need to replace the synthetic leather

Embodiment 1

[0028] Take 30 kg of melamine resin, 10 kg of polyurethane resin, 30 kg of methyl isobutyl ketone, 4 kg of tetrahydrofuran, and 3 kg of p-toluenesulfonic acid. Stir and mix the melamine resin, polyurethane resin, methyl isobutyl ketone and tetrahydrofuran evenly, and then seal and pack for use.

[0029] Before use, add p-toluenesulfonic acid and stir evenly to obtain a PVC synthetic leather treatment agent. Such as figure 1 As shown, the treatment wheel 1 with 100-120 mesh is selected, and the PVC synthetic leather treatment agent 2 is covered on the surface of the PVC synthetic leather 3 by gravure printing. The amount of PVC synthetic leather treatment agent 2 on the surface of PVC synthetic leather is 10-20g / m 2 . Then it is dried in an oven 4 at a drying temperature of 130° C. and a drying time of 1 min.

Embodiment 2

[0031] Get 40kg of melamine resin, 20kg of polyurethane resin, 40kg of methyl isobutyl ketone, 8kg of tetrahydrofuran, 10kg of silicon dioxide, and 8kg of p-toluenesulfonic acid. Stir and mix the melamine resin, polyurethane resin, methyl isobutyl ketone and tetrahydrofuran evenly, then add silicon dioxide and stir again, and then seal and pack for use.

[0032] Before use, add p-toluenesulfonic acid and stir evenly to obtain a PVC synthetic leather treatment agent. Such as figure 1 As shown, the treatment wheel 1 with 100-120 mesh is selected, and the PVC synthetic leather treatment agent 2 is covered on the surface of the PVC synthetic leather 3 by gravure printing. The amount of PVC synthetic leather treatment agent 2 on the surface of PVC synthetic leather is 10-20g / m 2 . Then it is dried in an oven 4 at a drying temperature of 130° C. and a drying time of 1 min.

Embodiment 3

[0034] Get 35kg of melamine resin, 15kg of polyurethane resin, 35kg of methyl isobutyl ketone, 6kg of tetrahydrofuran, 5kg of silicon dioxide, and 5kg of p-toluenesulfonic acid. Stir and mix the melamine resin, polyurethane resin, methyl isobutyl ketone and tetrahydrofuran evenly, then add silicon dioxide and stir again, and then seal and pack for use.

[0035] Before use, add p-toluenesulfonic acid and stir evenly to obtain a PVC synthetic leather treatment agent. Such as figure 1 As shown, the treatment wheel 1 with 100-120 mesh is selected, and the synthetic leather treatment agent 2 is covered on the surface of the PVC synthetic leather 3 by gravure printing. The amount of PVC synthetic leather treatment agent 2 on the surface of PVC synthetic leather is 10-20g / m 2 . Then it is dried in an oven 4 at a drying temperature of 130° C. and a drying time of 1 min.

Abstract

The invention relates to a PVC synthetic leather treatment agent and a preparing method thereof, and also relates to PVC synthetic leather with the PVC synthetic leather treatment agent covered on the surface and a preparing method thereof. The PVC synthetic leather treatment agent is characterized in that the PVC synthetic leather treatment agent is prepared by the following raw materials in portion by weight: 30 to 40 portions of malamine resin, 10 to 20 portions of polyurethane resin, 30 to 40 portions of methylisobutylketone, 4 to 8 portions of tetrahydrofuran, 0 to 10 portions of silicon dioxide, and 3 to 8 portions of paratoluenesulfonic acid. An intaglio printing method is adopted to coat the PVC synthetic leather treatment agent on the surface of the PVC synthetic leather, and then the PVC synthetic leather is dried; a treatment wheel with 100-120 meshes is selected, and the intaglio printing method is adopted to treat; and the drying temperature is 130 DEG C, the drying time is 1min, and the treatment amount on the surface of the PVC synthetic leather is between 10 and 20g/m<2>. The PVC synthetic leather treated by the PVC synthetic leather treatment agent can prevent the fouling, is easy to clean, and also has the characteristics of scraping resistance and weather resistance.

Description

technical field [0001] The invention relates to a PVC (polyvinyl chloride) synthetic leather treatment agent and a manufacturing method thereof, and also relates to a PVC synthetic leather covered with the PVC synthetic leather treatment agent and a manufacturing method thereof. Background technique [0002] With the continuous improvement and improvement of synthetic leather technology, the application range of synthetic leather products is becoming more and more extensive, and now it involves many civil decorative materials, such as furniture, clothing, car interiors, yachts, home interior decoration, hotels and other common In people's daily life, the technical standards of these civil decoration materials are very high, especially the surface cleaning function is relatively high. At present, most synthetic leather surfaces on the market are difficult to clean with ordinary household cleaners after being stained with stains. In order to clean the surface stains, people wi...
