Problems solved by technology

However, with the application and development of wood-plastic composite materials, it is found that the mechanical properties of PVC wood-plastic composite materials are not as good as expected. Although the PVC foam production process can obtain low-density lightweight products, it is also Weaken the comprehensive mechanical properties of composite materials

Abstract

The invention discloses a cabinet board which comprises a middle core layer and an outer coating layer, and the outer coating layer coats the outer surface of the middle core layer through extrusion molding; the middle core layer comprises PVC resin, wood flour, calcium carbonate, a synergist, a foaming agent, a stabilizer, a coupling agent, a processing aid and a lubricant; the outer coating layer comprises PVC resin, calcium carbonate, a synergist, a stabilizer, an impact modifier, a coupling agent, a processing aid, a lubricant and a flame retardant; the flame retardant comprises a shell, amiddle layer and an inner core, wherein the shell component is aluminum hydroxide, the middle layer component is hydrated zinc borate, and the inner core component is magnesium hydroxide. The particle diameter D50 of the flame retardant is smaller than 60 nm and the particle diameter D90 of the flame retardant is smaller than 100 nm; the outer coating layer plays a role in enhancing the mechanical property and flame retardance of the cabinet board, the middle core layer plays a role in reducing the density of the cabinet board, and therefore the physical and chemical properties of a traditional cabinet board are optimized.

Description

technical field [0001] The invention relates to the technical field of wood-plastic composite materials, in particular to a cabinet board. Background technique [0002] my country's wood-based panels are mainly used for furniture and cabinets in the home furnishing field. In recent years, with the improvement of the quality of wood-based panels, they have been used more and more in furniture, especially cabinets. At present, the vast majority of indoor wood-based panels in my country still use urea-formaldehyde resin adhesives (UF). Although GB 18580-2000 "Limits of formaldehyde release in wood-based panels and their products for interior decoration materials" clearly stipulates the limit value of formaldehyde release in wood-based panels and their products, and most wood-based panels can meet environmental protection requirements in use, but Particleboard produced with urea-formaldehyde resin adhesive will more or less release free formaldehyde, and the formaldehyde releas...
