Abstract

The invention discloses a mothproof veneer board, a mothproof faced veneer board and a manufacturing method thereof, relating to veneer boards used for industries of building materials, furniture, interior decoration, and the like. The mothproof performance of the existing veneer boards and faced veneer boards is reduced because of reducing the usage amount of free formaldehyde. In the invention,adhesive containing a pyrethroid moth proofer is coated on the surface of a dried veneer, and then processes of assembly, pressing and molding are carried out, wherein the pyrethroid moth proofer is in a microcapsule shape, and the weight ratio of the pyrethroid moth proofer to the adhesive is (0.15-1.0):100. An obtained product has good mothproof performance and long service life.

Description

technical field [0001] The invention relates to plywood used in building materials, furniture, interior decoration and other industries, in particular to an insect-proof plywood, an insect-proof veneer plywood and a manufacturing method thereof. Background technique [0002] With the improvement of people's awareness of environmental protection, people put forward higher and higher requirements for building materials, furniture products, and interior decoration materials, especially the control of free formaldehyde emission indicators in products is more stringent. [0003] Ordinary plywood, decorative veneer, and veneer plywood use low formaldehyde-emitting adhesives in the production process, which improves the environmental protection level of the product. E1, E0 and even formaldehyde-free products are also popular in the market. [0004] The aqueous solution of formaldehyde is called formalin, which is an efficient bactericidal disinfectant and can also be used as a pres...
