Novel anti-corrosion and anti-termite composite blockboard

Abstract

The invention provides a novel anti-corrosion and anti-termite composite blockboard. According to the technical scheme, the novel anti-corrosion and anti-termite composite blockboard comprises a timber body and is characterized in that the timber body is wrapped with a hot melt adhesive plastic board which is formed through hot pressing of hot melt adhesive and a wood-plastic board, and an anti-termite packing layer is arranged between the hot melt adhesive plastic board and the timber body; the anti-termite packing layer, the timber body 1 and the hot melt adhesive plastic board are glued and combined through an epoxy resin adhesive film, and the timber body is wrapped with the anti-termite packing layer; and the surface of the timber body is provided with conical protrusions, and the timber body and the hot melt adhesive plastic board are matched.

Description

technical field [0001] The invention relates to a woodworking board, in particular to a novel ant-proof composite blockboard. Background technique [0002] Blockboard, commonly known as large core board, is made of two veneers glued together in the middle. The total thickness of the double-sided glued veneers of the blockboard shall not be less than 3mm. The corner defects of various blockboards shall not exceed 5mm in width and 20mm in length within the nominal format. The middle board is made of high-quality natural wood boards after heat treatment (that is, drying in the drying room), processed into wooden strips of certain specifications, and spliced ​​by a jigsaw machine. The spliced ​​wooden boards are covered with two layers of high-quality veneer on both sides, and then glued by cold and hot presses. The outermost veneer of the blockboard is called the surface board, the inner veneer is called the middle board, the core layer is called the wood core board, and t...

Problems solved by technology

Because the blockboard is a special plywood, the principle of symmetry must also be followed in the production process to avoid warping and deformation of the board. As a thick board, the blockboard has the beautiful appearance and similar strength of ordinary thick plywood. Woodworking boards are lighter than thick plywood, but there are pollution sources such as formaldehyde and solvents, and poor acid, alkali and waterproof performance.

[0003] At present, with the continuous improvement of people's awareness of environmental protection, people pay more and more attention to the environmental protection of the living environment; especially in the urban environment with an increasing population, the existing panels have poor sound insulation effect, and serious noise pollution not only affects their own lives. Space, but also affect the daily life of the surrounding people
