Abstract：In this paper，by optimizing high-hardness emulsion and high-hardness powder，the preparation method of water-borne high hardness scratch resistant interior coating was studied，and the influence of emulsion type，high hardness powder，defoamer and antifreeze on the performance of the coating was determined. The results showed that when adding 30% silicone-acrylic emulsion RS-939W，8% eupoxite X7，compound adding silicone defoamer 334 with B199，and compound adding antifreeze ethylene glycol with freeze-thaw stabilizer FT100，the hardness of prepared interior wall coatings were H，and it had good scratch resistance.
Key words：interior wall coatings，high hardness，scratch resistance
