Embodiment 1

[0037] A kind of production method of easy decontamination highly wear-resistant durable sofa furniture synthetic leather, comprises the following steps:

[0038] (1) Coating a layer of colorless surface treatment slurry on the surface of synthetic leather for sofa furniture, the viscosity of the colorless surface treatment slurry is 1100cps / 25°C, and the amount of coating and sizing is 125g / m 2 ,, the coating thickness is 1 silk;

[0039] The weight ratio of each raw material component in the described colorless surface treatment slurry is:

[0040] Two-component polyurethane resin 100

[0041] Crosslinker 2

[0042] Antifouling treatment agent LS-91-077 10

[0043] Dimethylformamide 30;

Abstract

The invention discloses a method for producing a synthetic leather for sofa furniture that is easy to decontaminate, has high wear resistance and durability. The weight ratio of each raw material component in the color surface treatment slurry is: two-component polyurethane resin 80-120, crosslinking agent 1.5-2.5, dimethylformamide 30-45; (2) will be painted with colorless surface The sofa furniture treated with the pulp is dried with synthetic leather, the drying temperature is 120-125° C., and the drying time is 1-3 minutes; (3) the dried sofa furniture is cured with synthetic leather, and the curing temperature is It is 50-60 ℃, and the curing time is 47-49 hours. The synthetic leather for sofa furniture with high durability, easy decontamination and high wear resistance of the present invention has the performance that the surface can be easily wiped clean with a cloth after being polluted by oil, coffee, dust, etc., which greatly improves the product quality. Wear resistance and grade.

Description

technical field [0001] The invention relates to a surface treatment method of synthetic leather, in particular to a production method of synthetic leather for sofa furniture which is easy to decontaminate and highly wear-resistant and durable. Background technique [0002] With the development of social economy, people's quality of life is improving day by day. The grade and quality of sofa and other furniture products are also higher and higher. Therefore, the market share of synthetic leather for sofa furniture is increasing. However, the surface of the existing synthetic leather products for sofa furniture is easily polluted by some stolen goods, is not easy to clean, and has poor durability and wear resistance. For example, it is difficult to wipe with a cloth after being polluted by oil, coffee, dust, etc. Clean, which reduces the performance of the product and seriously affects the use and promotion of the product. Contents of the invention [0003] The invention pr...
