Paper surface gypsum fireproof color steel plate and its preparation process

Abstract

The invention relates to a gypsum plaster fireproof color plate. The color plate comprises desulfurized gypsum plaster plates, galvanized steel plates and two parallel color-coated steel plates, desulfurized gypsum plaster plates are arranged on the inner surfaces of two parallel color-coated steel plates, two desulfurized gypsum plaster plates are arranged at an interval and are supported by galvanized steel pipes, and galvanized steel plates are arranged on the peripheral sides of two desulfurized gypsum plaster plates; and the invention further discloses a preparation process. The color plate has the beneficial effects of being good in heat-insulating effect, suitable for thermal expansion and cold contraction, not prone to burst, high in fire resistance and capable of being repeatedlyused.

Description

technical field [0001] The invention relates to the technical field of fireproof steel plates, in particular to gypsum fireproof color steel plates on paper and a preparation process thereof. Background technique [0002] When preparing clean steel plates, it is also necessary to consider its fire performance. In order to achieve fire prevention, ordinary steel plates have many interlayers in the middle. Although they can effectively prevent fire in the initial stage of a fire, when the fire is strong, these interlayers cannot bear the force of thermal expansion, resulting in bursting. The fire resistance of the steel plate after bursting is not ideal. Moreover, even if it is a small fire, it cannot be used after it bursts, and its fire resistance is weak. [0003] And many manufacturers of fire-resistant color steel plates often make structural improvements, most of which are directly purchased from the market and then assembled after structural design; few consider the c...
