Problems solved by technology

[0002] Artificial leather appeared in 1948. The polyurethane resins used in traditional artificial leather production are all solvent-based resins. This type of polyurethane resin is based on acetone, butanone (MEK), toluene, xylene, acetic acid, ethyl ester and dimethyl formaldehyde. Amide (DMF) etc. are used as the main solvents. These solvents have great harm to the human body. In addition, they are also easy to cause pollution to the environment. In addition, various solvents are very flammable and can easily cause fires or explosions. ACCIDENT

Abstract

The invention discloses an environment-friendly waterborne polyurethane adhesive for artificial leather and a preparation method of the environment-friendly waterborne polyurethane adhesive. The environment-friendly waterborne polyurethane adhesive is prepared from the following raw materials in parts by weight: 120 to 130 parts of polyethylene glycol adipate, 22 to 26 parts of isophorone diisocyanate, 15 to 19 parts of hexamethylene diisocyanate, 5 to 7 parts of dipropylene glycol dibenzoate, 3 to 5 parts of p-phenylenediamine, 5 to 7 parts of ammonium ethoxylaurate, 4 to 5 parts of anilmomethyl triethoxy silane, 3 to 5 parts of stannous octoate, 6 to 8 parts of ammonium dihexenoate, 4 to 5 parts of butylene glycol, 4 to 6 parts of diisooctyl phenyl phosphite, 5 to 7 parts of ammonium dihydrogen phosphate, 2 to 4 parts of magnesium stearate and the like. When the adhesive disclosed by the invention is used, moisture in the air and on the surface of an adhered material or the adhered material contains substances including active hydrogen and the like, the adhesive is reacted with the substances to form chemical bonds including a urea bond, a hydrogen bond and the like, so that a binding effect is realized. Raw materials including magnesite, edible seaweed powder, chitosan acrylate and the like are added, so that the binding property of polyurethane is improved, the shrinkage stress and the thermal stress are reduced, the stability on thermal damages is enhanced and the viscosity of the adhesive is enhanced. The environment-friendly waterborne polyurethane adhesive has the advantages of no toxin and environment friendliness and meets the national requirements of China.

Description

technical field [0001] The invention relates to an adhesive, in particular to an environmentally friendly water-based polyurethane adhesive for artificial leather and a preparation method thereof. Background technique [0002] Artificial leather appeared in 1948. The polyurethane resins used in traditional artificial leather production are all solvent-based resins. This type of polyurethane resin is based on acetone, ethyl ketone (MEK), toluene, xylene, acetic acid, ethyl ester and dimethyl formaldehyde. Amide (DMF) etc. are used as the main solvents. These solvents have a greater harmful effect on the human body. In addition, they are also likely to cause pollution to the environment. In addition, various solvents are very flammable and can easily cause fire or explosion. ACCIDENT. Therefore, after the emergence of water-based polyurethane, it is imperative to replace solvent-based polyurethane with water-based polyurethane to prevent pollution from the source and ensure p...
