Abstract

The invention relates to moisture-resistant putty and a preparation method thereof. The moisture-resistant putty comprises raw putty stock which is prepared from the following components in parts by weight: 10-20 parts of white cement, 25-90 parts of coarse whiting, 0.3-0.5 parts of cellulose ether, 0..01-0.05 parts of starch ether, 0.1-15 parts of redispersible latex powder, and 0.2-5 parts of an early strength agent, wherein the film forming temperature of the redispersible latex powder is 0-10 DEG C. The moisture-resistant putty overcomes the defects that existing moisture-resistant putty is poor in early strength and prone to powder falling, delamination during polishing and the like, and the moisture-resistant putty has the advantages of being good in early strength and not prone to powder falling by adopting the preferable redispersible latex powder with the low film forming temperature and the early strength agent in cooperation with other preferable components in a system and the dosage proportions of the components.

Description

technical field [0001] The invention relates to a moisture-resistant putty and a preparation method thereof, which are applied in the field of functional putty production. Background technique [0002] The existing moisture-resistant putty is a large-scale circulation product and has been put into use nationwide. After entering November in most parts of the country, the temperature difference between morning and evening is large. The temperature during the day is above 10°C, but the temperature at night may be lower than 5°C. This makes the existing existing moisture-resistant putty on the wall prone to powder falling, grinding and delamination due to low ambient temperature and poor early strength. [0003] Therefore, it has become an urgent task to provide a moisture-resistant putty with good early strength and not easy to drop powder and its preparation method. Contents of the invention [0004] In order to overcome the shortcomings of the existing moisture-resistant ...
