Problems solved by technology

[0004] However, due to the limitations of the nature of PVC artificial leather itself, there is a problem of stiff hand feeling, especially when it is used as a surface material in interior decoration, it is prone to friction noise on its own surface, friction noise between the surface material and plastic parts, Or the friction noise of the surface material in contact with the driver and occupants

preparation example Construction

[0074] The invention also discloses a preparation method of polyvinyl chloride artificial leather, comprising the following steps:

[0075] Prepare polyvinyl chloride non-foamed layer and polyvinyl chloride foamed layer respectively;

[0076] placing the polyvinyl chloride foamed layer mixture and the polyvinyl chloride non-foamed layer mixture on the backing fabric in sequence for calendering and bonding to obtain a semi-finished product;

[0077] Coating the artificial leather treatment agent described in the above technical solution on the semi-finished product according to 45-70g / ㎡, forming a treatment layer;

[0078] Foaming and embossing the semi-finished product after forming the treatment layer to obtain polyvinyl chloride artificial leather.

[0079] According to the present invention, the polyvinyl chloride non-foaming layer mixture and the polyvinyl chloride foaming layer mixture are firstly prepared respectively.

[0080] The preparation method of the polyvinyl c...

Embodiment 1

[0089] After mixing 3 parts by weight of curing agent; 0.2 parts by weight of defoamer; 1.5 parts by weight of leveling agent; and 8 parts by weight of hand feeling agent, the auxiliary agent is obtained. Get 8 parts by weight of the auxiliary agent and mix it with 100 parts by weight of acrylic acid-modified water-based polyurethane, and use a viscosity modifier to adjust the viscosity to 30 seconds when it flows out through the hole at the bottom of the No. 3 Ford cup to obtain the artificial leather treatment agent.

Embodiment 2

[0091] After mixing 3 parts by weight of curing agent; 0.2 parts by weight of defoamer; 1.5 parts by weight of leveling agent; and 8 parts by weight of hand feeling agent, the auxiliary agent is obtained. Get 6 parts by weight of the auxiliary agent and mix it with 100 parts by weight of acrylic acid-modified water-based polyurethane, and use a viscosity regulator to adjust the viscosity to 40 seconds when it flows out through the hole at the bottom of the No. 3 Ford cup to obtain the artificial leather treatment agent.

Abstract

The invention relates to the field of auto interior decoration and in particular relates to an artificial leather treating agent, polyvinyl chloride artificial leather, a preparation method and an application thereof. According to the artificial leather treating agent, acrylic acid modified waterborne polyurethane per 100 parts by weight contains 5-10 parts by weight of an auxiliary agent, wherein the auxiliary agent comprises the following components in parts by weight: 3-8 parts of a curing agent, 0.01-0.2 part of a defoamer, 0.5-1.5 parts of a flatting agent and 8-15 parts of a feeling agent. The viscosity of the artificial leather treating agent is that the time of the artificial leather treating agent flowing out through a bottom hole of a #3 Ford cup is 30-40s. The artificial leather treating agent is coated to the surface of a base layer to form a treatment layer, wherein the coating amount is 45-70g/m<2>; and a semiproduct forming the treatment layer is foamed and knurled to obtain the polyvinyl chloride artificial leather. The polyvinyl chloride artificial leather applied to an automobile interior decorative material has the characteristic of reducing the frictional noise and meets the requirement of frictional noise of an interior decorative product.

Description

technical field [0001] The invention relates to the field of automotive interior decoration, in particular to an artificial leather treatment agent, polyvinyl chloride artificial leather, a preparation method and application thereof. Background technique [0002] In recent years, with the improvement of my country's consumption level, the demand for automobiles has also grown rapidly. With the increase of automobile production, automobile interior materials are also developing rapidly. When consumers buy cars, they not only pay attention to car functionality, safety, and exterior styling, but more and more consumers have higher and higher requirements for interior comfort. Therefore, in the field of interior design, from the traditional strong and durable, it gradually develops to comfort and refinement, and puts forward new requirements for the friction noise of interior products. [0003] Polyvinyl chloride artificial leather, that is, PVC artificial leather, is a plastic...
