Wherein, Cobb value is smaller, shows that the water resistance of coating paper is better.
It can be seen that styrene-butadiene latex made from the preparation method according to the present invention, and according to side described in comparative example
Styrene-butadiene latex made from method is compared, and more excellent caking property and water resistance can be obtained.
Specific embodiments of the present invention are described in detail above, but it is merely an example, the present invention is simultaneously unlimited
It is formed on particular embodiments described above.To those skilled in the art, any couple of present invention carries out equivalent modifications and
Substitution is also all among scope of the invention.Therefore, without departing from the spirit and scope of the invention made by equal transformation and
Modification, all should be contained within the scope of the invention.
