Embodiment 1

[0035] A water-based PVC automobile leather matting treatment agent, its raw material formula is as follows:

[0036]

[0037]

[0038] The preparation method is as follows:

[0039] Add water-based polyurethane resin and self-matting resin to the reaction kettle, start stirring, and raise the temperature to 70°C, keep it warm for 30 minutes; add silica matting powder, continue stirring for 30 minutes; then add leveling agent, wax emulsion, hand feeling agent and enhancer Thickener, continue to stir for 30 minutes; finally add deionized water, and stir for 30 minutes, cool and discharge to obtain water-based matting treatment agent for PVC automobile leather.

[0040] Results: The appearance of the water-based matting treatment agent for PVC automobile leather was milky white liquid without impurities, the solid content was 20%±2%, and the viscosity was 900CPS.

Embodiment 2

[0042] A water-based PVC automobile leather matting treatment agent, its raw material formula is as follows:

[0043]

[0044] The preparation method is the same as in Example 1, and the result: the appearance of the water-based matting treatment agent for PVC automobile leather is milky white liquid without impurities, the solid content is 20%±2%, and the viscosity is 1000CPS.

Embodiment 3

[0046] A water-based PVC automobile leather matting treatment agent, its raw material formula is as follows:

[0047]

[0048]

[0049] The preparation method is the same as in Example 1, and the result: the appearance of the water-based matting treatment agent for PVC automobile leather is milky white liquid without impurities, the solid content is 20%±2%, and the viscosity is 1200CPS.

Abstract

The invention discloses a delustering treating agent for waterborne PVC automobile leather. The delustering treating agent comprises, by weight, 30-50 parts of waterborne polyurethane resin, 5-20 parts of self-extinction resin, 1-3 parts of flatting agent, 1-5 parts of wax emulsion, 1-5 parts of hand feeling agent, 1-5 parts of silica extinction powder, 1-3 parts of thickening agent and 30-50 parts of deionized water. The delustering treating agent for the waterborne PVC automobile leather has good heat resistance, wear resistance, non-adhesion property and friction color fastness.

Description

technical field [0001] The invention relates to a leather surface matting agent, more specifically, the invention relates to a water-based matting treatment agent for PVC automobile leather. Background technique [0002] People need to apply a large amount of PVC artificial leather in daily life, and because a large amount of plasticizers and other materials are added in the production of PVC artificial leather, the produced PVC artificial leather is not ideal in terms of luster and hand feeling. In order to achieve a better and more ideal use effect, the leather surface must be treated during the leather production process to endow the leather surface with smooth, soft, matting, waterproof, anti-fouling and other comfortable feel and beautiful appearance. At present, the surface matting of polyvinyl chloride (PVC) artificial leather, especially PVC automotive leather, usually uses solvent-based surface treatment agents, which contain 85-90% organic solvents, and a large amo...
