Thin blockboard and manufacturing method thereof

Abstract

The invention relates to the field of thin blockboard manufacturing, in particular to a thin blockboard and a manufacturing method of the thin blockboard. The thin blockboard comprises a China fir core board layer in the middle, poplar single board layers which are respectively spliced on the upper surface of the China fir core board layer and the lower surface of the China fir core board layer, and Okoume single board layers which are respectively spliced on the outer surfaces of the poplar single board layers. Adjacent board layers are spliced according to the perpendicular direction of wood texture, and modified soya bean glue is adopted to splice adjacent board layers. The solid thin blockboard has high splicing strength and is low in formaldehyde release amount, and at the same time, has the advantages of being mould-proof, corrosion-proof, insect-proof and water-proof.

Description

technical field [0001] The invention relates to the field of blockboard preparation, in particular to a blockboard and a manufacturing method thereof. Background technique [0002] In recent years, due to the advantages of light weight, easy processing, good screw holding power, high strength, and no deformation, the blockboard has been widely used in furniture, doors, windows and covers, partitions, false walls, heating hoods, and curtain boxes. , is an ideal material for interior decoration and high-end furniture production. However, the vast majority of blockboards still use adhesives containing free formaldehyde. Although the products can meet the emission indicators stipulated in national standards, when the products are used in a large amount indoors, the pollution of the indoor environment by the formaldehyde released is still inevitable. . At present, the pollution to the living environment and the harm to people's health due to the extensive use of formaldehyde-co...

Problems solved by technology

However, the vast majority of blockboards still use adhesives containing free formaldehyde. Although the products can meet the emission indicators stipulated in national standards, when the products are used in a large amount indoors, the pollution of the indoor environment by the formaldehyde released is still inevitable.

At present, the pollution of the living environment and the harm to people's health due to the extensive use of formaldehyde-containing blockboards have become an urgent problem to be solved.
