The invention relates to a
straw antibacterial
flame retardant
composite material and a preparation method thereof, and belongs to the field of
composite material; the material contains the following raw materials in parts by weight: 61-64 parts of
straw, 15-18 parts of polyether
polyol, 15-18 parts of
isocyanic acid, 3-5 parts of an
artemisia argyi extract, 3-5 parts of a liquorice extract, 2-4 parts of a
coupling agent, 2-4 parts of a stabilizer, 2-4 parts of a
lubricant and 3-5 parts of a cyclic
phosphate flame retardant. The
straw has a natural hollow structure and has good heat preservation effect, through foaming and addition of the natural antibacterial agents
artemisia argyi extract and liquorice extract, the material has the advantages of
environmental protection and no
pollution, antibacterial and anticorrosion properties of the material are enhanced, and the service life of the material is prolonged; with addition of the
flame retardant, the flame retardant property of the material is increased; and the scientific
processing method is adopted, the preparation process is simple and is in line with the characteristics of low-carbon and economy, and the material can be used in manufacturing wallboards and fillers thereof, can be used for buildings, home furnishing, automobiles and other fields, and is suitable for industrialized production.
