Abstract

The invention discloses a bending-resistant composite fireproof board which is formed by four layers. The first layer is a vermiculite board with the thickness of 0.2cm-0.4cm, the second layer is a calcium silicate board with the thickness of 0.1cm-0.3cm, the third layer is a melamine board with the thickness of 0.2cm-0.5cm and the fourth layer is a granite board with the thickness of 0.4cm-0.6cm. The vermiculite board is provided with Teflon distributed at intervals. The composite board has good bending-resistant and fireproof performance.

Description

technical field [0001] The invention relates to a board, in particular to a fold-resistant composite fireproof board. Background technique [0002] The fireproof performance has a very important effect on the safety performance of the fireproof board. If the fire protection level is too low, in the application of the board, if there is an open flame, etc., the fireproof effect of the board will be poor, and it is easy to cause a fire. The flexural and compressive capabilities of the board also have a greater impact on the use of the board. The flexural strength of conventional plates is 5-10Mpa, and the flexural strength is low. When encountering a large impact force, the plates are prone to breakage and damage. By performing high-temperature bonding and molding of different plates, unexpected performance improvements may be achieved. Contents of the invention [0003] The technical problem to be solved: the problem of the conventional board's flexural performance and lo...
