Description
Technical Field
The utility model belongs to the technical field of the material of mating formation, relate to solid wood composite floor, especially relate to a polypropylene membrane veneer multilayer composite floor of EB solidification.
Background
The multilayer solid wood composite floor is prepared by coating special paint for the ultraviolet light curing floor, which has high performance, high wear resistance and high environmental protection, on a substrate which is a natural rare tree species veneer (veneer) with different thicknesses and a plywood made of solid wood veneers with criss-cross textures, and is widely applied to the household building material industry. However, with the shortage of forest resources, the resource limitation of the solid wood composite floor is increased, and particularly, the available resources are reduced rapidly when the solid wood composite floor is selected from hard broad-leaved tree species for decades or even hundreds of years. The price of raw materials is continuously rising, the yield is greatly reduced, and the requirements on the more noble multilayer surface plates of the multilayer solid wood composite floor are more and more strict.
Electron Beam (EB) curing technology is an important branch of radiation curing technology. The electron beam emitted from a cathode ray tube is linearly accelerated by an electric field, so that the energy of the electron beam reaches 100-400 KeV; the electron beam irradiates the coating containing unsaturated double bonds to initiate the polymerization of the coating, so as to achieve the aim of curing the coating, and the technology is widely applied to the fields of automobile coating curing and various coatings. In the electron beam/wire (EB) film, resin is polymerized by irradiating resin paint (liquid) with EB, thereby changing the properties of the substance, adding new functions to the substance, and instantly obtaining a film (solid) with high hardness. The EB curing technology is an environment-friendly, energy-saving and sanitary coating curing technology, accords with the national industry development direction, and is worth being vigorously promoted.
Chinese patent CN207808670U discloses an electronic wire cured film multilayer composite floor, which comprises a UV paint film, an electronic wire cured film and a multilayer substrate layer in sequence from top to bottom, wherein the multilayer substrate layer is a plywood formed by fast growing wood veneers through criss-cross lamination, and the electronic wire cured film is adhered on the upper surface of the plywood through a polyvinyl alcohol adhesive. The electronic wire cured film multilayer composite floor base material adopts the criss-cross base material of the original fast growing wood veneer. However, there are still several problems with this patent, such as: the annual ring lines are obvious, and sand printing or wood burrs are easy to generate to influence the surface effect; the surface is covered with a layer of UV paint, although partial lower layer can be covered, the phenomena of surface indentation, bulging and the like caused by the problems of base materials and sanding still exist, and the cost of the finished floor is increased to a certain extent; the polyvinyl alcohol glue for bonding has poor elasticity and bonding strength, low water resistance and the like.
