LATEX COMPOSITION FOR ASPHALT EMULSION
To provide a latex composition excellent in mixing property with an asphalt emulsion, and a latex-mixed asphalt emulsion excellent in adhesive strength and tire adhesion inhibition.SOLUTION: A latex composition for an asphalt emulsion includes: a copolymer latex including a copolymer containing a constitutional unit derived from one or more monomers selected from the group consisting of a conjugated diene monomer, an unsaturated carboxylic acid monomer, an aromatic vinyl monomer, and a (meth)acrylic monomer; and further a nonionic emulsifier and an anionic emulsifier, where the total content of constitutional units derived from the nonionic emulsifier, the anionic emulsifier and the unsaturated carboxylic acid monomer is more than 1.0 pts.mass and 10.0 pts.mass or less to 100.0 pts.mass of a total of constitutional units derived from all monomers.SELECTED DRAWING: None
【課題】本発明は、アスファルト乳剤と混合性に優れるラテックス組成物、及び、接着強さ及びタイヤ付着抑制に優れるラテックス混合アスファルト乳剤を提供することを目的とする。【解決手段】共役ジエン単量体、不飽和カルボン酸単量体、芳香族ビニル単量体、及び（メタ）アクリル系単量体からなる群より選ばれる１種以上の単量体に由来する構成単位を含有する共重合体を含む共重合体ラテックスを含み、さらに、ノニオン性乳化剤及びアニオン性乳化剤を含み、ノニオン性乳化剤、アニオン性乳化剤及び不飽和カルボン酸単量体に由来する構成単位の合計含有量が、全単量体に由来する構成単位合計１００．０質量部に対して、１．０質量部を超え１０．０質量部以下である、アスファルト乳剤用ラテックス組成物。【選択図】なし
