Abstract

The invention discloses a core-shell type tertiary carbon redispersible latex powder and a preparation method thereof. The core-shell type tertiary carbon redispersible latex powder is prepared from atertiary carbon polymer emulsion, a protective glue and an anti-caking agent through spraying and drying, wherein the tertiary carbon polymer emulsion is a core-shell type tertiary carbon polymer emulsion which is obtained by copolymerizing vinyl versatate and other monomers; the glass transition temperature Tg of a shell layer is lower than or equal to 5 DEG C; the glass transition temperature Tg of a core layer is higher than or equal to 13 DEG C. The core-shell type tertiary carbon redispersible latex powder can be used for producing environment-friendly coatings with high property and zero VOC (volatile organic compounds) without filming additives.

Description

technical field

[0001] The present invention relates to the field of polymer emulsion, redispersible latex powder and water-based latex coating; More specifically, the present invention relates to a kind of production zero VOC environmental protection coating required, based on the core-shell type polymer emulsion of tertiary carbonic acid vinyl ester Tertiary carbon redispersible latex powder and its preparation method. Background technique

[0002] Volatile organic compounds (Volatile Organic Compounds) have been identified as one of the culprits of smog. They not only pollute the environment and destroy the ecology, but also cause serious harm to human health and cause a huge waste of resources. At present, the annual emission of VOC in the field of coatings in my country exceeds 7 million tons, which has become one of the main sources of VOC emissions in my country. Therefore, reducing the VOC emissions in and related to coatings is an urgent problem to be solved. [00...
