Method for producing cabinet board by adopting damp-proof composite urea resin

Abstract

The invention relates to home building materials, in particular to a method for producing a cabinet board by adopting damp-proof composite urea resin. The cabinet board structurally comprises decorative paper, a China fir veneer, a chipboard and a backboard from top to bottom, wherein the four sides of the cabinet board are edged with aluminum alloy; damp-proof composite urea resin adhesives are smeared between the China fir veneer and the chipboard; damp-proof composite urea resin adhesives are smeared between the chipboard and the backboard; and the chipboard in the cabinet board adopts damp-proof composite urea resin adhesives as well. The cabinet board manufactured through the method has the properties of high water resistance, high adhesive strength and low formaldehyde residual volume and the damp-proof function. The raw materials adopted by the chipboard in production of the cabinet board are waste materials-leftover materials which can not be used in the process of manufacturing a multi-layer eucalyptus board after rotary cutting of the eucalyptus board. The leftover materials are used, so that wood materials are saved, and the production cost is reduced for enterprises.

Description

technical field [0001] The invention relates to a home building material, in particular to a method for producing cabinet panels by using moisture-proof composite urea-formaldehyde resin. Background technique [0002] As the saying goes, "Poor is better than a living room, richer than a kitchen". As the "finishing touch" of kitchen decoration, cabinet boards are paid more attention to. At present, the cabinet boards on the market also use particleboard as the core board, and particleboard is an important board type in wood-based panels. Compared with other board types, its production investment is relatively small, energy consumption is small, and cost is low. The requirements are not high, and the three leftovers, fast-growing wood, recycled waste wood and some non-wood materials can be used as raw materials for particleboard. Therefore, the development of particleboard industry in China, which is scarce in wood resources, has its unique advantages. The interior of the pa...

Problems solved by technology

[0005] In the above-mentioned patent, the adhesive used in the production process of the cabinet board is a waterproof modified urea-formaldehyde resin adhesive (the purpose is to reduce the formaldehyde content) modified urea-formaldehyde resin adhesive, and polyvinyl acetate emulsion is added, although It can also achieve the waterproof and moisture-proof effect, but the inventor found in the production practice that its bonding strength, residual formaldehyde, and waterproof and moisture-proof are not as good as the urea-formaldehyde resin modified by melamine.
