Environmentally-friendly antifouling agent for indoor materials and antifouling paints JP2001 234155 (2001-08-28)

The antifouling agent is obtained by using dicyandiamide (I), a polyene polyamine (II) and optionally urea in the presence of an ammonium salt or an acid, wherein C2- 10 Diamines (I and II)
The molar ratio depends on the conditions. Example: An antifouling agent was prepared by adding 1.5 mol of 35% HCl to a mixture of I1.5, ethylenediamine 1.5 and urea 0.5 mol, and reacting at 240° C. for 60 min.
Odorless adhesive containing formaldehyde-based thermosetting resin for wood substrates

JP 2001 240835 (200109-04)

This allylamine-based polymer adhesive is suitable for wood building materials. Example: 20 parts of urea-melamine resin (MA 216A) 100, flour 16, water 9, NH4Cl, and 15% polyethyene polyamine (PAA15) aqueous solution were mixed to prepare an adhesive. It was coated on 3 pieces of Liu'an wood veneer and then pressed (120°C, 78 s). The obtained adhesive strength of the plywood was 25 MPa, formaldehyde was released (20°C, 24 h).

Adhesives and Adhesive Sheets Containing (Meth)Acrylate Type Block Copolymers and Their Manufacturing. JP 2001 234147 (2001-08-28)

The adhesive has good adhesion and cohesive strength and is obtained with block copolymers of ≥2 blocks and carboxylic acid crosslinking compounds (as crosslinkers). The copolymer is obtained by living radical polymerization of a (meth)acrylic precursor monomer, and this block A is then coupled with a block copolymer B, and the copolymer B is composed of (meth)acrylic acid The esters are obtained in the required sequence and the block A is then converted into blocks of (meth)acrylic acid to effect cross-linking. Example: 15g of butyl acrylate, 0.539g of 2,2'-bispyridinium, and 0.220g of copper bromide with 0.323g of 2-bromo-
The 2-hydroxyethyl 2-methylpropanoate mixture was heated at 50°C for 12 h to give an active polymer which was first polymerized with butyl acrylate and then polymerized with propylene tert-butyl ester. Give a kind
ABA triblock copolymers. A solution of 40 g of this copolymer in 40 mL of toluene was mixed with 4 g of a cation-exchanged exchanger at 120° C. for 2 h to obtain a block copolymer containing converted acrylic acid units. Polyepoxide compound made an adhesive.

High-viscosity vinyl polymer adhesive for carpet composition JP2001 234144 (2000-08-28)

The adhesive has good water resistance and low temperature storage stability. It is a water-dilutable emulsion, a polymer dispersion colloid containing vinyl ester monomers and a polymer containing vinyl alcohol (
The dispersant has a 1,2-glycol bond ≥1.7 mol %). Example: Vinyl acetate is mixed in the presence of polyvinyl alcohol (degree of polymerization 1700, degree of saponification 98.0 mol%, content of 1,2-diols 2.2 mol%), tartaric acid, water and dibutyl phthalate. This kind of adhesive has good water resistance, adhesive strength and low temperature storage stability on plywood.
