Abstract

The invention discloses a non-asbestos latex pick-up plate for sealing, and belongs to the technical field of sealing materials. The non-asbestos latex pick-up plate for sealing is prepared by the following steps: by weight, successively weighing 18-25 parts of aramid fibers, 15-20 parts of mixed plant fibers, 5-8 parts of aluminum sulfate, 4-8 parts of nano-powder mixed liquid, 10-15 parts of latex, 5-10 parts of metal fibers, 8-13 parts of graphite oxide, 5-7 parts of casein and 3-5 parts of borax, mixing the aramid fibers and the mixed plant fibers, and successively adding the latex, the aluminum sulfate, the nano-powder mixed liquid, the metal fibers, the graphite oxide, the casein and the borax, stirring and mixing to obtain a blank, and adding the blank to a sheet-making machine forsheet-making. The prepared non-asbestos latex pick-up plate for sealing has the excellent tensile strength and creep resistance, and has the higher compression rebound resilience.

Description

technical field [0001] The invention discloses a non-asbestos latex scoop board for sealing, which belongs to the technical field of sealing materials. Background technique [0002] Sealing materials are widely used in petroleum, chemical, machinery and other industries. For a long time, asbestos-based sealing materials have been the main components in the field of sealing materials because of their unique advantages such as chemical corrosion resistance, heat resistance, flame retardancy, easy processing and low cost. However, asbestos fibers will cause great harm to human health in the process of manufacturing, processing and use. With the recognition of the hazards of asbestos, the use of new non-asbestos sealing materials to replace traditional asbestos sealing materials has become the most significant change in the field of sealing materials in recent years. . [0003] Non-asbestos latex sheet (referred to as non-asbestos latex sheet) is an important sealing material,...
