Description
本発明は、接着剤用共重合体ラテックス、詳しくは、ゴムと繊維とを接着する接着剤用共重合体ラテックス、および、接着剤用共重合体ラテックスを含有する接着剤組成物に関する。 The present invention relates to a copolymer latex for an adhesive, specifically, a copolymer latex for an adhesive that adheres rubber and a fiber, and an adhesive composition containing a copolymer latex for an adhesive.
従来、共重合体ラテックス(A)50〜90質量%と、共重合体ラテックス(B)10〜50質量%とを含有する接着剤用共重合体ラテックスが知られている。 Conventionally, a copolymer latex for an adhesive containing 50 to 90% by mass of the copolymer latex (A) and 10 to 50% by mass of the copolymer latex (B) is known.
共重合体ラテックス(A)は、ブタジエン系単量体35〜75質量%、ビニルピリジン系単量体10〜30質量%およびスチレン系単量体10〜55質量%を含む単量体組成物(a)を乳化重合して得られる。共重合体ラテックス(B)は、ブタジエン系単量体3〜25質量%、ビニルピリジン系単量体0〜5質量%、スチレン系単量体55〜97質量%、エチレン系不飽和カルボン酸0〜10質量%、および、共重合可能な他の単量体0〜20質量%を含む単量体組成物(b)を乳化重合して得られる(例えば、下記特許文献1参照。)。 The copolymer latex (A) is a monomer composition containing 35 to 75% by mass of a butadiene monomer, 10 to 30% by mass of a vinyl pyridine monomer, and 10 to 55% by mass of a styrene monomer. It is obtained by emulsion polymerization of a). The copolymer latex (B) contains 3 to 25% by mass of a butadiene-based monomer, 0 to 5% by mass of a vinylpyridine-based monomer, 55 to 97% by mass of a styrene-based monomer, and 0 ethylene-based unsaturated carboxylic acid. It is obtained by emulsion polymerization of a monomer composition (b) containing 10% by mass and 0 to 20% by mass of another copolymerizable monomer (see, for example, Patent Document 1 below).
しかし、上記した特許文献1に記載の接着剤用共重合体ラテックスでは、接着力と、タイヤコードの柔軟性との両立を図ることが困難である。 However, with the copolymer latex for adhesives described in Patent Document 1 described above, it is difficult to achieve both adhesive strength and flexibility of the tire cord.
そこで、本発明の目的は、接着力と、タイヤコードの柔軟性との両立を図ることができる接着剤用共重合体ラテックスおよび接着剤組成物を提供することにある。 Therefore, an object of the present invention is to provide a copolymer latex for an adhesive and an adhesive composition capable of achieving both adhesive strength and flexibility of a tire cord.
