Embodiment 1

[0019] According to the cashmere treatment agent for synthetic leather of the present embodiment, it is directly mixed by the following components by weight: 100 parts of anti-yellowing high-brightness polyurethane resin; 7 parts of dry sliding wax powder; 4 parts of silica matting powder 10 parts of glass microspheres with a particle size of 30-50 μm; 3 parts of epoxy soybean oil; 3 parts of benzyl silicone oil; 2 parts of plasticizer (tributyl citrate); 40 parts of dimethylformamide; 40 parts of ester; 30 parts of methylal; 30 parts of xylene. See Table 1 for the technical specifications of the cashmere treatment agent, which meet the application requirements.

Embodiment 2

[0021] According to the cashmere treatment agent for synthetic leather of this embodiment, its formula is the same as that of Example 1, but it is prepared by the following preparation method: 40 parts of dimethylformamide and 40 parts of butyl acetate are added to 100 parts of bright polyurethane resin. 30 parts of methylal, 30 parts of xylene, 3 parts of benzyl silicone oil, 3 parts of epoxidized soybean oil, 2 parts of plasticizer tributyl citrate), stir at high speed until evenly dispersed, and then add 4 parts of silicon dioxide matting powder, 7 parts of dry sliding wax powder and 10 parts of glass microspheres are uniformly dispersed, ground by a grinder and filtered to obtain the cashmere treatment agent for synthetic leather. See Table 1 for the technical specifications of the cashmere treatment agent, which meet the application requirements.

Embodiment 3

[0023] According to the cashmere treatment agent for synthetic leather of the present embodiment, it is directly mixed by the following components by weight: 105 parts of anti-yellowing bright polyurethane resin; 8 parts of dry wax powder; 5 parts of silica matting powder ; 8 parts of glass microspheres with a particle size of 30-50 μm; 4 parts of epoxidized soybean oil; 2 parts of benzyl silicone oil; 1 part of plasticizer (tributyl citrate); 45 parts of dimethylformamide; 45 parts of ester; 35 parts of methylal; 35 parts of xylene. See Table 1 for the technical specifications of the cashmere treatment agent, which meet the application requirements. See Table 1 for the technical specifications of the cashmere treatment agent, which meet the application requirements.

Abstract

The invention relates to a velvet finishing agent for synthetic leather and a preparation method thereof. The velvet finishing agent consists of the following raw materials in parts by weight: 80-120 parts of polyurethane resin, 3-10 parts of dry smooth wax powder, 2-8 parts of silicon dioxide extinction powder, 6-15 parts of glass microspheres with particle size of 5-60 microns, 1-6 parts of epoxidized soybean oil, 1-6 parts of phenmethyl silicon oil, 1-6 parts of plasticizer, 30-60 parts of dimethylformamide, 30-50 parts of butyl acetate, 20-40 parts of methylal and 20-40 parts of dimethylbenzene. The velvet finishing agent for synthetic leather provided by the invention has low cost and good velvet feel, can be used through multiple technologies such as roller painting, printing and the like, and is widely applicable. In the invention, a preparation technology of uniformly dispersing before grinding and filtering is adopted, and the prepared finishing agent can obtain more delicate velvet feel; and moreover, as the yangbuck powder requiring accurate temperature control and long-time foaming is not used, the preparation is easier.

Description

technical field [0001] The invention relates to a surface treatment agent for synthesis, in particular to a suede treatment agent for synthetic leather and a preparation method thereof. Background technique [0002] At present, the surface treatment methods of leather products including luggage, clothing, shoes, etc. are various, and the effect styles are varied: high-gloss high-solid, oily leather style, polished style, crazy horse discoloration, yangbuck, etc., whether it is in surface effects or in In terms of feel, it is still pursuing the imitation leather effect. [0003] Velvet-feeling materials have always been popular in the market. Because velvet-feeling materials have a delicate hand feel, natural luster, and superior tactility, and are closest to the effect of genuine leather, the development and improvement of velvet-feeling materials has always been a key issue. The cashmere material currently on the market is mainly Yangbuck foaming resin, but the main disadv...
