Problems solved by technology

[0002] The sofa made of ordinary synthetic leather is easy to burn and cause a fire when exposed to an open flame, causing serious casualties and property losses. The sofa is also easy to burn and deform due to small fire points such as cigarette butts falling, which seriously affects the appearance of the sofa.

Embodiment

[0023] Embodiment: a kind of high flame-retardant sofa leather manufacture method, concrete steps are as follows:

[0024] Step 1: Wet Mixing Ingredients:

[0025] a: Stir 5-10kg of dimethylformamide and 0.5-2kg of color paste at high speed for 60-90 minutes, filter and set aside;

[0026] b: Stir 100-120kg dimethylformamide, 20-30kg wood powder and 5-20kg flame retardant for 30 minutes, let stand for 20-45 minutes, mix with the slurry in step a and stir evenly for later use;

[0027] c: 100kg polyurethane wet-process resin and the slurry in step b are mixed and stirred for 20-40 minutes and then defoamed;

[0028] Step 2: Wet bass production:

[0029] Apply and scrape the degassed slurry in step c on the textile fabric fibers, immerse in an aqueous solution of dimethylformamide with a mass percentage concentration of 18-22%, and obtain a a wet bass;

[0030] Step 3: Dry Mixing Ingredients:

[0031] Stir 90-100kg of polyurethane dry-process resin, 15-20kg of dimethylforma...

Abstract

The invention discloses a high-flame-retardant sofa leather production method, which comprises the following steps of: wet-process mixing for proportioning: evenly agitating dimethylformamide and color paste and filtering the mixture slurry for future use; evenly agitating dimethylformamide, wood powder and flame retardant, standing the mixture for 20-45 minutes, and evenly mixing and agitating the mixture with the mixed slurry; adding polyurethane wet-process resin, evenly agitating the mixture and removing foam; coating the slurry on fabric fibers and immersing the fabric fibers in dimethylformamide water solution to obtain a wet-process bass through solidification, multi-pass water squeezing, water washing and drying; evenly agitating polyurethane dry-process resin, dimethylformamide, butanone, flame retardant, assistants and toner to obtain dry-process slurry; coating the dry-process slurry on patterned release paper, bonding the wet-process bass through bonding agent, separating the release paper after drying, finally and fully immersing the obtained product in flame-retardant water solution, squeezing the product, and wrinkling the product to obtain high-flame-retardant sofa leather. The high-flame-retardant sofa leather production method has the advantages that the process is simple and the production operation is facilitated; and the synthetic leather produced by adopting the production method provided by the invention has the advantages of fire prevention, high safety, attractive appearance, staining resistance and the like.

Description

technical field [0001] The invention relates to a method for making artificial leather, in particular to a method for making high flame-resistant sofa leather. Background technique [0002] The sofa made of ordinary synthetic leather is easy to burn and cause a fire when exposed to an open flame, causing serious casualties and property losses. Contents of the invention [0003] In order to overcome the above-mentioned defects, the present invention provides a method for producing high flame-retardant sofa leather, which is simple in process, and the produced product has the functions of fire prevention, safety, appearance and stain resistance. [0004] The technical scheme that the present invention adopts in order to solve its technical problem is: a kind of high fire-retardant sofa leather manufacture method, concrete steps are as follows: [0005] Step 1: Wet Mixing Ingredients: [0006] a: Stir 5-10kg of dimethylformamide and 0.5-2kg of color paste at high speed for ...
