Abstract

The invention discloses a fireproof coating for a steel structure, and belongs to the technical field of fireproof coatings. The fireproof coating comprises the following components in parts by weight: 30-50 parts of base material resin, 15-20 parts of a dehydration catalyst, 5-10 parts of a carbonizing agent, 6-10 parts of a foaming agent, 5-10 parts of a phosphate group-containing flame retardant, 3-8 parts of carboxymethyl cellulose, 3-5 parts of aluminum hydroxide, 1-2 parts of carbon nanotubes, 1-2 parts of basalt fibers and 10-15 parts of water. The invention further provides a preparation method and application of the fireproof coating for the steel structure. According to the fireproof coating for the steel structure, the strength and the fire resistance limit of an expanded carbonlayer are improved by adding the carbon nanotubes and the basalt fibers on the basis of the expanded fireproof coating. Meanwhile, the phosphate group-containing flame retardant and the inorganic flame retardant aluminum hydroxide are added, so that the fireproof performance can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of fireproof coatings, and in particular relates to a steel structure fireproof coating, a preparation method and an application thereof. Background technique [0002] With the development of modern industrial technology, building houses can be manufactured in batches like machine production, as long as the prefabricated house components are transported to the construction site and assembled. During the construction of this house, the steel structure is one of the main types of building structures. It is mainly composed of steel beams, steel columns, steel trusses and other components made of section steel and steel plates. Compared with concrete structures, it has higher strength and lower weight. Lightweight, good overall rigidity, strong resistance to deformation, and easy construction, it is widely used in the construction of long-span, super high-rise, super-heavy buildings and other fields.
