Abstract
A method for producing a dip-molded article, the method including steps of immersing a mold for dip molding in a coagulant solution to deposit the coagulant on the mold for dip molding; providing a latex composition containing a carboxy-modified conjugated diene polymer latex which is a dispersion of carboxy-modified conjugated diene polymer particles having a volume average particle size of 500 to 2,000 nm in water; and immersing the mold for dip molding having the coagulant deposited thereon in the latex composition to obtain a dip-molded article having a thickness of 0.02 to 0.19 mm.
Claims9
A method for producing a dip-molded article, comprising steps of:
- immersing a mold for dip molding in a coagulant solution to deposit a coagulant on the mold for dip molding;
- providing a latex composition containing a carboxy-modified conjugated diene polymer latex which is a dispersion of carboxy-modified conjugated diene polymer particles having a volume average particle size of 500 to 2,000 nm in water;
- and
- immersing the mold for dip molding having the coagulant deposited thereon in the latex composition to obtain a dip-molded article having a thickness of greater than or equal to 0.02 mm and less than 0.08 mm, wherein:
- a concentration of the coagulant in the coagulant solution is 1 to 4 wt %,
- a solids content of the latex composition is 10 to 20 wt %,
- the latex composition comprises a sulfur-based vulcanizing agent,
- an amount of the sulfur-based vulcanizing agent is 0.2 to 0.6 parts by weight, with respect to 100 parts by weight of the carboxy-modified conjugated diene polymer,
- a glass mold having a non-roughened surface is used as the mold for dip molding, and
- a surface roughness Ra of the glass mold is 0.01 to 100 μm.
