Abstract

The invention discloses a flame-retardant foamed sheet which is characterized by being prepared from the following raw materials in parts by weight: 100 parts of SG-3PVC, 5-7 parts of light calcium carbonate, 10-14 parts of titanium dioxide, 4-5 parts of azodicarbonamide, 1.4-1.6 parts of hexamine, 2.8-3.2 parts of nanometer titania, 4-6 parts of precipitated barium sulphate, 1-2 parts of sodium dodecyl benzene sulfonate, 1-2 parts of dibutyltin dilaurate, 4-5 parts of diethylene glycol dibenzoate, 2-3 parts of zinc oxide, 1-2 parts of dicumyl peroxide and 6-8 parts of modified packing. The foamed sheet has an uncommon excellent flame-retardant effect, is low in density, light in weight, sound-insulated, heat-insulated, attractive in appearance and suitable for serving as a building material and is convenient and simple in raw material source, low in production cost and suitable for large-area popularization.

Description

technical field [0001] The invention relates to a board, in particular to a flame-retardant foamed board. Background technique [0002] The foamed board made of polyvinyl chloride is mainly used in the manufacture of advertising cabinets and bathroom cabinets. It was the first to introduce equipment and technology from Europe, and the quoted product standards also refer to European standards. The density of the board is relatively high. In recent years, with the development of domestic equipment, especially the development of additives, the density of the board has been greatly reduced, which can reach 0.4~0.45g / cm3, thus greatly improving the application space of the board and reducing the cost of use , but how to further reduce the density of the board and still achieve better performance is a bottleneck in the research of lightweight boards. [0003] Flame-retardant foaming materials are widely used in various occasions that require fire protection because of their light...
