Corrosion-resistant fiberboard

Abstract

The invention discloses a corrosion-resistant fiberboard. By creatively applying a protective layer onto the surface of a blank board in the later stage of the production link of the fiberboard, the blank board of the fiberboard can be sealed under the condition of superior water content, and the performance of the fiberboard is ensured; meanwhile, an ultraviolet shielding agent is added to a protective layer solution, so that even if the prepared fiberboard is applied under high-intensity illumination or long-time illumination, it can be ensured that the fiberboard keeps low performance attenuation speed under the condition of being irradiated by ultraviolet light contained in natural light; shell powder is added as an additive component in raw materials of a board body so that processingauxiliary agents volatilized from the fiberboard in the later stage can be partially absorbed by the shell powder to achieve the effect of suppressing the escape of harmful gas; meanwhile, in combination with the sealing effect of the protective layer wrapping the outer surface of the board body, after long-term use of the fiberboard, it can still be ensured that the harmful gas volatilized fromthe fiberboard can be suppressed and meet national environmental protection requirements, and the health of people and animals in the application environment is guaranteed.

Description

technical field [0001] The invention relates to the field of profiles, in particular to a corrosion-resistant fiberboard. Background technique [0002] In the existing production of fiberboard, most of the production personnel only pay attention to the test results after the product is off-line, but often ignore the tracking of the degree of physical strength reduction of the product in the application environment for several months or years. Profiles that are widely used in such fields, and the resulting durability issues and safety hazards also need to be paid attention to, especially some fiberboards are used in high temperature, high humidity and high light environments. If there is no reliable durability guarantee, Then the resulting maintenance cost and safety monitoring cost are also huge, especially at present, many fiberboard manufacturers do not pay enough attention to the product performance attenuation caused by light, in the combination of high ultraviolet rays,...

[0002] In the existing production of fiberboard, most of the production personnel only pay attention to the test results after the product is off-line, but often ignore the tracking of the degree of physical strength reduction of the product in the application environment for several months or years. Profiles that are widely used in such fields, and the resulting durability issues and safety hazards also need to be paid attention to, especially some fiberboards are used in high temperature, high humidity and high light environments. If there is no reliable durability guarantee, Then the resulting maintenance cost and safety monitoring cost are also huge, especially at present, many fiberboard manufacturers do not pay enough attention to the product performance attenuation caused by light, in the combination of high ultraviolet rays, high humidity and high temperature. In cases where the performance degradation of the fiberboard has exceeded the guidance of the corresponding literature
