摘要
In the present technology, a thermally expandable microcapsule complex is blended in a rubber component, the thermally expandable microcapsule complex being obtained by preparing an aqueous solution of a water-soluble polymer having a concentration of 1 to 30 mass %, adding from 5 to 60 parts by mass of cellulose fibers to 100 parts by mass of the aqueous solution to prepare a liquid dispersion (1), adding from 10 to 200 parts by mass of thermally expandable microcapsules to the liquid dispersion (1) to prepare a liquid dispersion 2), and evaporating the moisture content of the liquid dispersion (2).
