Abstract

The invention discloses an agriculture straw regeneration fire-proof heat preservation plate material. The agriculture straw regeneration fire-proof heatpreservation plate material comprises raw materials, by weight, 60-80 parts of agriculture straw, 10-15 parts of binder, 3-6 parts of metal oxide, 3-7 parts of water-proof agent, 3-5 parts of fire retardant, 15-20 parts of modified kaolin, 12-18 parts of white cement and 20-26 parts water. The agriculture straw regeneration fire-proof heat preservation plate material has the excellent properties of rapid prototyping, heat insulation and heat preservation, inflaming retarding, mould proof, deliquescence resistance, high strength and the like, the plate material is divided into a pressed inner core and an outer surface coating layer, the problems of being prone to breaking billet, sticking plate and demoulding are solved, continuous production is achieved, and the production efficiency is improved greatly; and meanwhile, the source of the main raw materials of the agriculture straw regeneration fire-proof heat insulation plate material is wide, the cost is low, the technology is simple and clear, and the high practical value and the good application prospect are achieved.

Description

technical field [0001] The invention relates to the technical field of agricultural straw utilization, in particular to a recycled agricultural straw fire-proof and thermal insulation board and a preparation method thereof. Background technique [0002] At present, there are many types of thermal insulation boards for building exterior walls in China, but their quality and performance are uneven. Polyurethane foam, polystyrene foam and their composite boards, which were widely used in the past, are not only flammable but also emit a lot of smoke (containing toxic carcinogens such as hydrogen cyanide and dioxin) if exposed to high temperature or open flames. In recent years, rapid development such as rock wool insulation board, in the process of production and construction, there will be a large number of cotton-like fibers floating into the air, polluting the air environment and irritating human skin; Poor, fragile and other defects affect the construction quality.
