Problems solved by technology

[0002] Traditional office furniture leather is generally based on ultra-fine fiber non-woven fabrics, and then the mixed slurry of water-based polyurethane and nano-silver oxide-loaded wood powder is used to form a functional coating on the release paper by scraping method, and combined with Substrate bonding, drying, cooling, and peeling to obtain a microfiber nonwoven fabric with a functional coating. The resulting PU contains dimethyl fumarate (DMF), which is not environmentally friendly and harmful to the human body, and its thickness thick, dull

Abstract

The invention discloses a method for producing environmentally friendly paper PU for office furniture. 80-100 parts of polyurethane surface layer resin without dimethyl fumarate, 40-70 parts of ethyl cellosolve, 0.5-2 parts of assistant 80-100 parts of polyurethane adhesive resin without dimethyl fumarate, 20-60 parts of ethyl cellosolve, 0.5-2 Parts of additives and 5-8 parts of environmentally friendly toner are mixed to obtain dry-process adhesive; the dry-process fabric is coated on the release paper, and after drying, the dry-process adhesive is coated on it, and the solvent is volatilized to 40 ‑80% dry, paste the base paper on the surface of the dry-process adhesive, dry, cool, and separate from the release paper to obtain the finished product. The finished product obtained by the present invention does not contain dimethyl fumarate (DMF), which is environmentally friendly , does not harm human health, and the overall thickness is thin, soft and tough, bright in color, bright in pearl, strong and durable.

Description

technical field [0001] The invention relates to a method for producing artificial leather, in particular to a method for producing environmentally friendly paper PU for office furniture. Background technique [0002] Traditional office furniture leather is generally based on ultra-fine fiber non-woven fabrics, and then the mixed slurry of water-based polyurethane and nano-silver oxide-loaded wood powder is used to form a functional coating on the release paper by scraping method, and combined with Substrate bonding, drying, cooling, and peeling to obtain a microfiber nonwoven fabric with a functional coating. The resulting PU contains dimethyl fumarate (DMF), which is not environmentally friendly and harmful to the human body, and its thickness Thick, dull in color. Contents of the invention [0003] In order to make up for the above deficiencies, the present invention provides a method for producing environmentally friendly paper for office furniture PU. The production m...
