Document Type and Number:
WIPO Patent Application WO/2021/036129
Kind Code:
A1
Abstract:
Disclosed are an integrally molded sand roller and a manufacturing method therefor. The method comprises the following steps: step S1, mixing an abrasive, a binder, and a filler at a preset ratio to obtain a slurry; step S2, pouring the slurry into a mold and placing same for 8 hours or more, and maintaining the environment temperature above 20ºC during the placing process; step S3, after the placing time is reached, demolding a blank body in the mold; and step S4, hardening the blank body according to a preset temperature curve to obtain the sand roller. The sand roller is prepared by a integrated molding method. The process steps thereof are simple and easy to operate; furthermore, molds of different shapes can be selected in order to prepare sand rollers of various shapes, and the range of application is wide. The sand roller, prepared by using a specific slurry formulation and hardening temperature, has a better molding effect, and is firm and stable.
