Embodiment

[0042] Next, the present invention will be described more specifically by way of examples and comparative examples.

Synthetic example 1

[0043] (Synthesis Example 1: Synthesis of Acrylic Resin (C-1))

[0044] 3.0 parts by mass of polyoxyethylene alkyl ether sodium sulfate and 263 parts by mass of ion-exchanged water were added to a reaction vessel equipped with a stirrer, a thermometer, a reflux cooler, a nitrogen gas introduction pipe, and a dropping tank, and the temperature was raised to 80°C. While maintaining the temperature, continuously dropwise add 442.5 parts by mass of n-butyl acrylate, 40.0 parts by mass of acrylonitrile, 5.0 parts by mass of methacrylic acid, 5.0 parts by mass of acrylamide, and 2.5 parts by mass of itaconic acid from the dropping tank over 4 hours. , A monomer mixture of 5.0 parts by mass of polyoxyethylene-1-(allyloxymethyl)alkylsulfate ammonium salt and 125 parts by mass of ion-exchanged water. Along with this, the aqueous solution containing 1.3 parts by mass of ammonium persulfate and 5.0 parts by mass of ion-exchanged water was continuously added dropwise over 4 hours. 30 min...

Synthetic example 2

[0045] (Synthesis Example 2: Synthesis of Acrylic Resin (RC-1))

[0046] 18.0 mass parts of 10 mass % sodium hydroxide aqueous solution and 1.5 mass parts of 25 mass % ammonia water used in the synthesis example 1 were changed into 3.0 mass parts of 25 mass % ammonia water, except that it was carried out in the same manner as synthesis example 1 to obtain a non-volatile Aqueous dispersion of acrylic resin (RC-1) with composition 50.0%. Metal hydroxides are not included in the basic compound used as a neutralizing agent.

Abstract

Provided is an aqueous resin composition for flocking which is characterized in that a carboxyl group-containing polymer (A) contains an acrylic resin (C) neutralized with a basic compound (B) containing a metal hydroxide (b1) as an essential component, a polyoxazoline compound (D), and an aqueous medium (E). Since the aqueous resin composition for flocking provides flocked products that exhibit excellent flocking strength and substrate adhesion as well as excellent long-term stability, the aqueous resin composition for flocking can be suitably used for various flocked products.

Description

technical field [0001] The present invention relates to a water-based resin composition that can be used for flocked processed goods. Background technique [0002] Flocking is a processing method in which short fibers are attached to a substrate coated with an adhesive using electrostatic force. It is used in various applications centering on household goods because of its heat insulation and texture. Adhesives generally use water-based resins, among which acrylic emulsions are mostly used. However, self-crosslinking type acrylic emulsions have low adhesive strength to short fibers and cannot obtain sufficient flocking strength, so studies are underway to improve strength and durability by adding a water-soluble crosslinking agent . [0003] Wherein, proposed: the acrylic resin aqueous composition (for example, referring to the patent) containing water-dispersible acrylic copolymer, water-soluble or water-dispersible macromolecular compound, and water-soluble macromolecula...
