Embodiment 1

[0012] PU: 80--120, dimethylformamide: 15--22, butanone: 75--85, ethyl acetate: 35--45, NC: 5--8, viscose staple fiber: 4-- 7. Nylon staple fiber: 2--6, polyvinyl chloride wax: 5--10, fine silica: 3--7. According to the above-mentioned components and proportions, a method for treating the resin on the surface of leather, the process steps are: 1) stir butanone, ethyl acetate, dimethylformamide, and NC for 5 minutes according to the proportions;

[0013] 2) At this point, add polyvinyl chloride, fine silicon dioxide, stir for 3 minutes, ball mill for 5 minutes and filter;

[0014] 3) Add viscose staple fiber, nylon staple fiber and PU resin and stir for 8 minutes.

Embodiment 2

[0016] PU: 100, DMF: 20, MEK: 80, Ethyl Acetate: 40, NC: 6, Viscose Staple Fiber: 5, Nylon Staple Fiber: 3, PVC Wax: 8, Fine Dioxide Silicon: 5.

[0017] According to the above components and proportioning, a method for treating the resin on the leather surface, the process steps are:

[0018] 1) Stir butanone, ethyl acetate, dimethylformamide, and NC for 5 minutes according to the proportion;

[0019] 2) At this point, add polyvinyl chloride, fine silicon dioxide, stir for 3 minutes, ball mill for 5 minutes and filter;

[0020] 3) Add viscose staple fiber, nylon staple fiber and PU resin and stir for 8 minutes.

[0021] Wherein embodiment 2 is the best embodiment, and the product that it makes is the best product.

Abstract

The invention discloses resin for treating the leather surface and a manufacturing method thereof. The resin for treating the leather surface comprises the following compositions: 80 to 120 portions of PU, 15 to 22 portions of dimethyl formamide, 75 to 85 portions of butanone, 35 to 45 portions of ethyl acetate, 5 to 8 portions of NC, 4 to 7 portions of rayon staple fibers, 2 to 6 portions of nylon staple fibers, 5 to 10 portions of polyethylene wax and 3 to 7 portions of fine silicon dioxide. The manufacturing method comprises the following technological steps: 1) the butanone, the ethyl acetate, the dimethyl formamide and the NC are uniformly stirred for 5 minutes according to the mixture ratio; 2) polyvinyl chloride and the fine silicon dioxide are added into the mixture, stirred for 3 minutes, subjected to ball milling for 5 minutes, and filtered; and 3), the rayon staple fibers, the nylon staple fibers and the PU resin are added into the mixture and stirred for 8 minutes. The leather for treating the leather resin has the advantages that the requirements on abrasion resistance, scraping resistance, flection resistance, the color fastness and so on meet the international standards; water resistance, moisture permeability, water pressure resistance, solvent resistance, strong acid and strong alkali resistance, external moisture variation resistance and moisture variation resistance meet the standards; and the oily light sense is strong and permanent.

Description

Technical field: [0001] The invention relates to a treatment agent for leather surface, in particular to a BZ-3077 resin for leather surface treatment. Background technique: [0002] At present, leather products such as clothing, luggage, decoration, packaging, military leather and other surface treatment methods are various, including color-changing crazy horse, high-solid cracking, high-solid ironing, bright surface treatment agent, matte surface treatment agent, cracking Scorching, bright crystal high solid, etc., among which the surface gloss technology is relatively mature and popular, such as various existing bright surface treatment agents, bright crystal high solid, high solid ironing. However, the leather surface is easy to change color, not easy to withstand high temperature, not wear-resistant, not scratch-resistant, not resistant to twists and turns, poor color fastness, oily and smooth, weak and not durable, so it is necessary to mix a resin to treat the leather...
