Problems solved by technology

The artificial leather with deep texture that is common in the market is generally made by hot roller embossing, but the surface of artificial leather made by hot roller embossing is generally not scratch-resistant, and experiments have shown that it can only reach about 100 times at most; while the surface layer is scratch-resistant Generally, the surface of artificial leather is very thick, resulting in smooth surface and stiff hand feeling.

Embodiment 1

[0012] The processing method of moisture curing type vacuum embossed artificial leather adopts the following steps

[0013] 1) Artificial leather vacuum embossing: ordinary artificial leather is used as the base embryo and heated to 160-170°C by far-infrared rays, vacuum embossed by a ceramic embossing roller equipped with a vacuum pump, and cooled to room temperature after embossing. The use of far-infrared rays makes the heating process uniform and the energy waste is small, and then passes through the ceramic embossing roller equipped with a vacuum pump. three-dimensional texture.

[0014] 2) Preparation of moisture curing treatment agent: the formula is volume ratio, moisture curing silicone resin LS-3001, 100 parts; toluene TOL, 20 parts; curing agent 7016, 2 parts; defoamer 530, 0.5 parts And leveling agent U-60B, add 0.5 parts into the dye water and stir evenly at high speed. When stirring, use a 32KW high-speed mixer to stir for about one hour, until the dye water and...

Abstract

The invention discloses a method for processing moisture cured vacuum embossed artificial leather, which comprises the following steps that: common artificial leather is taken as a base and heated by far infrared rays to be between 160 and 170 DEG C; and a ceramic embossing roller provided with a vacuum pump is used for vacuum embossing, and the common artificial leather is cooled to normal temperature, undergoes moisture curing posttreatment, and is stood for more than 24 hours to form a finished product. When passing a heating roller, the artificial leather is tightly absorbed onto the surface of the ceramic roller by the pull of vacuum in the roller, and then generates grains with strong third dimension; and the surface of the product has very high physical scratch resistance which exceeds 1,000 times in back-and-forth friction scratch resisting tests through experiments, and has the rebound elasticity, super smooth handfeel, anti-fouling and excellent hydrolytic resistance.

Description

technical field [0001] The invention belongs to the field of chemical industry, and in particular relates to a processing method of moisture curing type vacuum embossed artificial leather. Background technique [0002] With the continuous progress of the development of artificial leather, people have higher and higher requirements for the three-dimensional effect of the artificial leather grain and the physical and chemical properties of the leather surface layer, which has led to a lot of efforts in the leather manufacturing process to meet the market demand in these two aspects. The artificial leather with deep texture that is common in the market is generally made by hot roller embossing, but the surface of the artificial leather made by hot roller embossing is generally not scratch-resistant, and experiments have shown that it can only reach about 100 times at most; while the surface layer is scratch-resistant Types of artificial leather generally have a thick surface, r...
