Abstract

The invention discloses a preparation method for an anticorrosive antibacterial wood fiber composite. The preparation method for the anticorrosive antibacterial wood fiber composite comprises the steps that a layer of nanometer oxide suspension liquid is sprayed onto the surface of the wood fiber composite and dried; then a layer of poly-dimethyl siloxane treatment fluid is sprayed onto the surface of the wood fiber composite and dried; and finally, a layer of nanometer oxide suspension liquid is sprayed onto the surface of the wood fiber composite again and dried, and the anticorrosive antibacterial wood fiber composite is prepared. The nanometer oxide suspension liquid is one or several of nanometer aluminum oxide suspension liquid, nanometer titanium dioxide suspension liquid and nanometer zinc oxide suspension liquid. According to the preparation method for the anticorrosive antibacterial wood fiber composite, the surface of the wood fiber composite is subjected to spraying treatment; the inflaming-retarding, smoke-suppressive, anticorrosive and antibacterial properties of the composite are improved, and meanwhile, the hydrophobic property of the surface of the composite is strengthened significantly; and moisture is prevented from entering the interior of the composite and destroying the living environment of microorganism, and the service life and the anticorrosive antibacterial durability of wood are improved significantly.

Description

technical field [0001] The invention belongs to the field of wood processing and utilization, and in particular relates to a preparation method of an antiseptic and antibacterial wood fiber composite material. Background technique [0002] Wood (wooden materials) and its products are important materials in the fields of home furnishing and construction due to their unique and excellent characteristics. Wood fiber composite material is a kind of fiber composite board made by mechanically separating and chemically treating wood or natural plant fibers, adding adhesives, waterproofing agents and other additives, and then molding under high temperature and high pressure. Wood fiber composite material is a kind of flammable material with great fire hazard. Once a fire breaks out, it will seriously threaten people's life and property safety; The main cause of casualties. Wood fiber composite material is also a material that is perishable, easily corroded by bacteria (easy to bre...
