Abstract

The invention discloses a delayed-combustion-retarding high-temperature-resisting workshop primer. The key technology is that high-temperature film-forming materials are used. Two high-temperature film-forming materials are compounded in the formula, the melting points of the high-temperature film-forming materials are respectively in a range of 480-490 DEG C and a range of 680-700 DEG C, accordingly a primary film material can be followed to form a secondary continuous film and a ternary continuous film before the high-temperature heat weightlessness is not yet invalid completely, and coatings are ensured to be not crack. Simultaneously, the heat resistance of the coatings reaches to more than 800 DEG C, the area of the burning loss is very small, and smoke is hardly produced in the cutting or welding operation process.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to a fire-resistant, extended-temperature-resistant shop primer and a preparation method thereof. Background technique [0002] Since the early 1950s, shop primers have been used as pretreatment primers for large steel structures such as super cruise ships and offshore oil rigs. In order to adapt to the assembly line operation, the shop primer needs to meet the requirements of fast drying, excellent rust resistance, good weldability and mechanical properties. [0003] At present, the widely used shop primer is based on polyvinyl butyral and ethyl silicate hydrolyzate, and the pre-coating primer is compounded with zinc powder. month), the burn-out area during hot working is large, and the resistance to negative cathodic protection points is poor, so it is not suitable for the underwater part of the hull equipped with cathodic protection systems. Therefore, its application is lim...
