Putty with defoaming and foam inhibiting functions, and preparation method thereof

The invention relates to putty with defoaming and foam inhibiting functions, wherein the putty comprises the following components in parts by weight: 65-85 parts of heavy calcium carbonate powder, 1-5parts of ordinary Portland cement, 2-6 parts of a water reducing agent, 3-5 parts of redispersible latex powder, 2-7 parts of cellulose ether and 7-14 parts of a defoaming mixture, wherein the defoaming mixture comprises diatom mud and an amorphous silicon dioxide mixture, the diatom mud plays a role in foam inhibition, and the amorphous silicon dioxide mixture plays a role in defoaming. The invention further discloses a preparation method of the putty with the defoaming and foam inhibiting functions. The putty has the beneficial effects that bubbles are easy to eliminate and can be effectively inhibited, and bubbles are not prone to being generated in the painting process. 本发明涉及一种自带消泡抑泡腻子，按重量份算包含以下组分：65~85份的双飞粉，1~5份的普通硅酸盐水泥，2~6份的减水剂，3~5份的可再分散性乳胶粉，2~7份的纤维素醚，7~14份的消泡混合剂；所述的消泡混合剂包括硅藻泥、非结晶性二氧化矽的混合物，硅藻泥起到抑制泡的作用，非结晶性二
