Waterborne surface treating agent for PVC and PU artificial leather and preparation method and product thereof

Abstract

The invention discloses a waterborne surface treating agent for PVC and PU artificial leather, and the surface treating agent is prepared from the following components: 25-60 parts of waterborne aliphatic polyurethane resin, 5-25 parts of waterborne acrylic resin, 10-35 parts of water, 5-15 parts of isopropanol, 0.1-3 parts of a poly-2-methyl-4-isothiazolin-3-one compound, 1-5 parts of a dispersant, 0.1-5 parts of a paracresol and dicyclopentadiene butyl compound, 0.1-5 parts of polyether modified polydimethyl siloxane, 0.1-5 parts of a silane coupling agent, 0.1-8 parts of propylene glycol phenyl ether, 0.1-8 parts of matting powder and 0.1-5 parts of an acrylate polymer. Correspondingly, the invention also provides a preparation method of the waterborne surface treating agent for PVC and PU artificial leather. The waterborne surface treating agent for PVC and PU artificial leather has multiple functions, integrates multiple properties of scratch resistance, wear resistance, high temperature resistance and yellow stain resistance, can achieve the operating requirements by only one-step treatment, and is simultaneously suitable for PVC and PU artificial leather.

Description

technical field [0001] The invention relates to the technical field of PVC and PU artificial leather, in particular to a water-based surface treatment agent for PVC and PU artificial leather, a preparation method for the water-based surface treatment agent for PVC and PU artificial leather, and the PVC made by using the water-based surface treatment agent for PVC and PU artificial leather Artificial leather and PU artificial leather. Background technique [0002] People need to apply a large amount of PVC and PU artificial leather in daily life, but when producing PVC and PU artificial leather, a large amount of plasticizer and other materials are added, so that the produced PVC and PU artificial leather are 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 co...

Problems solved by technology

But above-mentioned surface treating agent is oily, and oily surface treating agent uses a large amount of organic solvents, and organic solvent can be more or less residual on leather surface, and long-term use can affect the health of user, and in the production process The volatilization of organic solvents will affect the health of production workers and pollute the surrounding environment

[0005] In addition, the currently commercially available PVC and PU artificial leather water-based surface treatment agents also have the following disadvantages: the general water-based surface treatment agent has a single function and cannot be multi-functional at the same time. For example: if the user needs to pre-treat and emboss the artificial leather It is also required that the treated artificial leather has the function of wear resistance and yellowing resistance. The user first selects a high temperature resistant surface treatment agent to emboss the surface of the artificial leather, and then treats it with a scratch-resistant, wear-resistant and yellowing-resistant surface treatment agent. It increases the number of times of surface coating and increases the production cost

[0007] The above reference document is to solve the problem of poor leveling and insufficient bonding strength of water-based resin on the surface of PVC artificial leather, but its function is single, and it cannot have multiple properties of scratch resistance, wear resistance, high temperature resistance, and yellowing resistance at the same time.

However, adding anti-scratch agents, anti-wear agents, high-temperature-resistant agents or anti-yellowing agents simply and superimposedly to the existing water-based surface treatment agents will damage the leveling and cohesiveness of the surface treatment agent itself

In addition, the surface treatment agent in the reference document is only suitable for PVC, not for PU, with a narrow scope of application and a single function
