ざるを得ないということが多々あった。2. Description of the Related Art When a redispersible powder resin is stirred with water, it is easily redispersed into an original emulsion state.
It is widely used in cement admixtures, powder coatings, powder adhesives, and the like, because it does not contain water, so that it has excellent storage stability without fear of freezing and that it can mix powders. As the range of use expands, so does the demand for physical properties of the resin, and powder resins of various resin compositions are required. However, since the redispersible powder resin is in the form of a fine powder, there is a danger of dust explosion due to static electricity and spontaneous ignition during storage, and is subject to regulations such as dangerous goods shipping and storage regulations. Therefore, even if a redispersible powder resin having good performance is developed, it has often been necessary to give up practical use due to the danger.

い。DETAILED DESCRIPTION OF THE INVENTION The redispersible powder resin used in the present invention is preferably a powder obtained by drying a synthetic resin emulsion obtained by emulsion-polymerizing a vinyl monomer using a protective colloid. When it is stirred with water, it returns to the original emulsion state. An emulsion using a surfactant without using a protective colloid tends to be easily blocked at the time of spray drying and tends to have poor redispersibility. As the protective colloid used here,
Water-soluble polymers such as polyvinyl alcohol and derivatives thereof, cellulose derivatives, vinyl polymers containing hydrophilic groups such as carboxyl groups, hydroxyl groups, and sulfonic acid groups are exemplified, and among these, polyvinyl alcohol is preferable.

ある。The reducing agents used in the present invention include sodium bisulfite, ascorbic acid, thioglycolic acid,
Oxalic acid, Mohr's salt and the like can be mentioned. The mixing ratio of the redispersible powder resin and the reducing agent in the present invention is 0.1 to 10 parts by weight of the reducing agent per 100 parts by weight of the redispersible powder resin. If the amount is less than 0.1 part by weight, the effect of preventing spontaneous ignition is not sufficient, and if it is more than 10 parts by weight, the physical properties of the resin itself are adversely affected. The inventor considers why the addition of the reducing agent can prevent dust explosion and spontaneous ignition of the redispersible powdered resin composition as follows. Dust explosion and spontaneous ignition of the redispersible powdered resin composition are due to static electricity charged to the fine powder particles. However, when a reducing agent is added, the energy of the static electricity is absorbed and dust explosion and spontaneous ignition can be prevented.
