Embodiment
[0009] Embodiment: a kind of synthetic antelope leather, take weight ratio as benchmark: 22-32 parts of polyvinyl alcohol (being called for short PVA), 8-14 parts of starch (can be wheat, rice and corn etc.), 14-18 parts of polymethyl Methyl acrylate (abbreviated as PM, which is a strengthening agent), 500-700 parts of water, 23-30 parts of sulfuric acid (dilute sulfuric acid with a concentration of 2%-5%) and 23-27 parts of formaldehyde.
[0010] A preparation process for synthetic antelope leather, under normal temperature and pressure: put polyvinyl alcohol, starch and polymethyl methacrylate into water, heat, dissolve and stir, after cooling (18-24 hours) to normal temperature, add formaldehyde and then add sulfuric acid Stir again, and then pour into the mold, shape at a temperature of 75°C-85°C, and then cool.
[0011] The product of the present invention has suitable wiping friction, fast water softening speed after drying, good elastic texture, better cleaning effect, ...

Abstract
The invention discloses a synthetic chamois, and a manufacture process thereof. The synthetic chamois provided by the invention is manufactured from the following raw materials in parts by weight: 22-32 parts of poly(vinyl alcohol), 8-14 parts of starch, 14-18 parts of poly(methyl methacrylate), 500-700 parts of water, 20-30 parts of sulfuric acid (2-5% diluted sulfuric acid) and 23-27 parts of formaldehyde. The manufacture process provided by the invention comprises the following steps of: adding poly(vinyl alcohol), starch and poly(methyl methacrylate) to water at normal temperature and normal pressure, heating and stirring for dissolving, cooling to normal temperature, adding formaldehyde, then adding sulfuric acid, stirring, injecting to a mold, molding at the temperature of 75-85 DEG C, cooling, demolding, centrifuge-drying, cleaning, carrying out mildewproof treatment, packaging and checking to obtain a product. The obtained product has the characteristics of proper wiping friction force, high water-encountering softening speed after being dry and hard, good elasticity and texture, good cleaning effect, easy use and low cost increase (increased by only 5%) and has an appearance similar to true leather, in short, the synthetic chamois provided by the invention has good texture and low cost.
Description
technical field [0001] The invention relates to a synthetic artificial leather and its preparation process, in particular to a synthetic antelope leather and its preparation process. Background technique [0002] PVA (i.e. polyvinyl alcohol) and PM (i.e. polymethyl methacrylate) strengthening agent are mixed together, add water and heat to dissolve, when the temperature drops to normal temperature, it enters the assembly line for the production of polyester cloth process, and then puts it into the steam room Steamed. [0003] The surface of the previous product is too smooth, easy to fit and has high friction. It feels dry when wiped on the object, and the softening speed is slow when it meets water after drying. Contents of the invention [0004] In order to overcome the above-mentioned defects, the invention provides a synthetic antelope skin and a preparation process. The synthetic antelope skin has suitable wiping friction and has a fast softening speed when it meets ...
