Fire-proof material, fire retardant module and fire-proof plate prepared from the same

Abstract

The invention discloses a fireproof material and a fireproof module and a fireproof board made of the material. It includes raw vermiculite and mainly includes the following components, and the parts by weight of each component are: 1 to 40 parts of raw vermiculite; 50-90 parts of cooked vermiculite; 15-25 parts of binder; 2 parts or less of graphite; the preferred amount of each component is: 10-20 parts of raw vermiculite; 60-80 parts of cooked vermiculite; 20 parts of binder parts; graphite is less than or equal to 1 part. The fire-blocking module and the fire-proof board are made of the above-mentioned fire-proof materials mixed and pressed. Utilizing the characteristics of thermal expansion of raw vermiculite, raw vermiculite is used instead of expanded graphite, which is a safe and effective fireproof material. It can be applied to various fireproof materials, and is especially suitable for fireproof modules, fireproof modules, firewalls, fireproof boards and the like made of fireproof materials.

Description

technical field [0001] The invention relates to a fireproof material. Background technique [0002] With the development of science and technology and the improvement of people's safety awareness, fireproof materials have received more and more attention from all walks of life, and their applications have become more and more extensive. Various types of fireproof modules, fireproof modules, firewalls, etc. have emerged. The main component of existing new fireproof materials is vermiculite. The prior art usually uses a mixture of cooked vermiculite, graphite, and adhesives. The main function of graphite is as an expansion agent, which expands when exposed to fire. The expansion agent is used in the fireproof material, so that the fireproof material can expand after being exposed to fire to seal the gaps in the firewall or the wall or the cable hole, etc., and play an effective role in fire prevention. Therefore, it is necessary to contain a sufficient amount of expansion age...

AI Technical Summary

Problems solved by technology

Existing fireproof materials mainly use graphite as the expansion agent, generally containing 5-10% graphite. It is good to use graphite as the expansion agent, but it will produce black smoke after graphite encounters fire, which will affect the evacuation and escape of personnel, and will Inhaled into the body, affecting health
