Abstract

Disclosed is a chloroprene polymer latex composition for water-based one-pack type adhesives having well-balanced initial adhesive force, contact properties, storage stability and spray coating properties, characterized by comprising 60-95 mass% (in terms of solid content) of a chloroprene polymer latex (A), 5-40 mass% (in terms of solid content) of an acrylic resin latex (B) containing an acrylic polymer having a glass transition temperature of -50 to 0oC, and 0.02-5 parts by mass (in terms of solid content), per 100 parts by mass (containing water) of the sum of said chloroprene polymer latex (A) and said acrylic resin latex (B), of a surfactant (C) represented by general formula (1): RO-(CH2CH2O)n-SO3M (1) wherein R represents an aliphatic alkyl group having 5 to 20 carbon atoms on average; M represents sodium or ammonium; and n (average) is from 2 to 60.

Description

technical field [0001] The present invention relates to a chloroprene-based polymer latex composition having strong initial adhesive force and excellent contact (adhesive) properties, spray coating properties, and storage stability. More specifically, it relates to the use of a one-component water-based adhesive suitable for at least one of the two adherends to be bonded is a soft material, especially suitable for foams for furniture and building materials (Foam) and adherends such as wood or foam, etc., for one-component water-based adhesive applications, a chloroprene-based polymer with an excellent balance of high initial adhesion, contactability, and high storage stability latex composition. Background technique [0002] Conventionally, vinyl acetate-based polymers, chloroprene-based polymers, acrylate-based polymers, natural rubber, polyurethane-based polymers, etc. have been used as polymers for adhesives. High adhesive force can be obtained by low-pressure bonding t...
