  • Patent number: 10894343
    Abstract: A rigid nylon porous material sheet is produced by the adhesive bonding of kinked nylon fibers having lengths of 1 to 5 inches. These fibers are cut from melt spun nylon or harvested from clean carpet fibers by shearing. The adhesive used is glycol, which attacks nylon at 180° C. forming a gel on the surface of the kinked fibers, but does not attack the nylon fibers when the kinked fiber assembly is cooled to 150° C. to precipitate ultrafine nylon within the gel. The fiber assembly is heated to 160° C. to bond the nylon fibers. It is then washed in hot water to remove unused glycol. The other adhesive is polyurethane, which is applied to the kinked fibers using coupling agents of aqueous resorcinol and vinyl pyrrolidone.

The polyurea system comprises as components: A) an isocyanate-functioning prepolymer, which can be derived by reacting aliphatic isocyanates with polyoles, and B) an amino-functioning ester of aspartic acid. According to the invention, water and/or tertiary amine is added to the system, in order to increase the reacting speed of the prepolymer with the amino-functioning ester of aspartic acid while decreasing the setting time at the same time.

  • Patent number: 9234068
    Abstract: A novel method for the preparation of an aqueous polyacrylate modified polyurethane dispersion is disclosed. The preparation method includes three main steps: a) preparation of polyacrylate polymer or copolymer emulsion; b) preparation of polyurethane prepolymer with carboxylic groups and neutralization treatment to the carboxylic groups; and c) dispersion and chain-extension of polyurethane prepolymer by adding the polyacrylate emulsion into the polyurethane prepolymer under vigorous agitation, or other mechanical operation. The aqueous polyacrylate modified polyurethane dispersion has self-crosslinkability when an unsaturated acetoacetoxy compound is used for the preparation of the polyacrylate emulsion.
