Method for producing cabinet board with anti-insect and anti-mold composite urea-formaldehyde resin

Abstract

The invention relates to a home building material, especially a method for producing cabinet board with anti-insect and anti-mold composite urea-formaldehyde resin. The cabinet board comprises from top to bottom: decorative paper, cunninghamia lanceolata veneer, particleboard and backboard; besides, the cabinet board is surrounded by aluminum alloy trim. The contact surface between the cunninghamia lanceolata veneer and particle board is coated with anti-insect and anti-mold composite urea-formaldehyde resin adhesives, which are also applied to the contact surface between the particleboard and backboard as well as the particleboard in the cabinet board. The cabinet board manufactured according to the invention has strong water resistance, high bonding strength, littleformaldehyde residue as well as anti-insect and anti-mold functions. Raw materials used for production of the particleboard in the cabinet board are the waste and scrap materials which cannot be used for production of the multi-layer eucalyptus board after peeling the eucalyptus wood, and the home building material utilizes the scraps to save wood and reduce productioncosts of the enterprises.

Description

technical field [0001] The invention relates to a home building material, in particular to a method for producing cabinet panels by using an insect-proof and mildew-proof compound 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 i...
