Abstract

The invention relates to a straw antibacterial flame retardant 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: 55-60 parts of straw, 15-18 parts of polyether polyol, 15-18 parts of isocyanic acid, 3-5 parts of a honeysuckle extract, 3-5 parts of a pine needle 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 halogen-free intumescent flame retardant. The straw has a natural hollow structure and has good heat preservation effect, through foaming and addition of the natural antibacterial agents honeysuckle extract and pine needle 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 with adopting of the scientific processing method, the preparation process is simple and is in line with the characteristics of low-carbon and economy, and the material can be used for manufacturing wallboards and fillers thereof, can be used in buildings, home furnishing, automobiles and other fields, and is suitable for industrialized production.

Description

technical field [0001] The invention belongs to the field of composite materials, and in particular relates to a straw antibacterial and flame-retardant material and a preparation method thereof. Background technique [0002] As a natural cellulose fiber, straw fiber has good biodegradability and can become an environmentally friendly product. Not only are these resources not being well utilized at present, but we can see the burning smoke in the fields every summer and autumn. These fumes bring inconvenience to people's life and work, and greatly affect our living environment. [0003] Wall panels are commonly used materials for home decoration, with various styles and functions. People can choose the appropriate wall panels according to their needs. After decoration, people will find that the wall panels are prone to mold, especially in humid environments, the service life of the wall panels is shorter and not durable. Existing wall panels also have other disadvantages,...
