DISPERSING REINFORCING PIGMENTS INTO RUBBER LATEX |
摘要 |
<p>METHOD OF DISPERSING REINFORCING PIGMENTS IN A LATEX There is disclosed a process for blending rubber latices with carbon black or other reinforcing pigments which comprises the use of a 60/40 to 40/60 butadiene/methacrylic acid latex which has been converted to a water soluble polymer through treatment with an alkali metal hydroxide. Said converted butadiene/methacrylic acid latex is then combined with dry carbon black at a level of 1 to 2 percent butadiene/methacrylic acid dispersing latex solids based on weight of the carbon black. The blended carbon black butadiene/methacrylic acid dispersion is added to rubber latices prior to coagulation. More specifically, this invention is concerned with a carbon black dispersion and its addition to a rubber latex.</p> |
