High-performance intumescent fireproof felt and preparation method thereof

Abstract

The invention relates to a high-performance intumescent fireproof felt and a preparation method thereof, and relates to the field of chemical materials. The fireproof felt comprises the following rawmaterials in parts by weight: 15-50 parts of a waterborne benchmark film-forming resin or emulsion, 10-30 parts of deionized water, 30-60 parts of fireproof flame-retardant filler, 10-15 parts of titanium dioxide, and 5-10 parts of a film-forming auxiliary agent. The beneficial effects are as follows: the preparation method is simple, and the equipment requirement is low; the selected raw materials do not contain any toxic components such as halogen, asbestos and the like, and the coating expands and does not ignite in the event of fire or high temperature, does not release the halogen-containing toxic gas, and belongs to the new generation of fire retardant coatings; the fireproof felt does not contain any organic solvents, is close to zero VOC emission, and is green and environment-friendly; the fireproof felt has the advantages and characteristics that carbon is formed in fire, the expansion foaming speed is rapid, the carbon-forming strength is high, the stability and integrity offoams can be maintained, and the like, the fireproof level can be high to F120, and the fireproof time is up to 120 min; and the intumescent fireproof felt has good damping and sound insulation effects.

Description

technical field

[0001] The invention relates to the field of chemical materials, in particular to a high-performance intumescent fireproof blanket and a preparation method thereof. Background technique

[0002] With the development of urbanization, buildings and residents are more and more concentrated, and fire safety is more important. Certain fire prevention measures must be taken for building materials, otherwise, once a fire breaks out, many people will be killed and injured, resulting in immeasurable loss of life and property. Fireproof coatings are widely used in many public and commercial buildings due to their advantages of convenient construction, flexibility and easy transformation.

[0003] The traditional method is to apply thick fireproof mortar and thin water-based intumescent fireproof paint on the outer surface of the steel for fire protection. The limitation of fire retardant coatings is that the construction period is long and multiple brushings are requ...
