Problems solved by technology

[0002] At present, the adhesives commonly used in plywood production include ordinary urea-formaldehyde glue, environment-friendly urea-formaldehyde glue and isocyanate glue, etc. Common urea-formaldehyde glue produces plywood with high production efficiency and good gluing performance, but the formaldehyde emission of the product is also high, which is Production and sales are strictly prohibited by the state; the production of plywood with environmentally friendly urea-formaldehyde glue, the formaldehyde emission can reach the national standard E 2 Grade or E 1 Requirements above grade, but the production efficiency is low, and the product's gluing performance is poor; isocyanate glue produces plywood, and the formaldehyde emission can reach the national standard E 0 Grade requirements, its environmental protection is good, but the production cost is high, the market prospect is not broad

Abstract

The invention discloses paint-free ecological plywood made of poplar base materials and a production process for the paint-free ecological plywood. On one hand, the paint-free ecological plywood made of the poplar base materials comprises a plywood body made of poplar base materials, and melamine resin adhesive impregnated decorative paper is arranged on the upper outer side and the lower outer side of the plywood body respectively. On the other hand, the production process is used for producing the paint-free ecological plywood made of the poplar base materials. The paint-free ecological plywood has the advantages of fine environmental performance, moisture resistance and mildew and pest resistance, easiness in processing, attractive and gorgeous appearance, small deformation coefficient and the like.

Description

technical field [0001] The invention relates to a plywood in the technical field of wood production, in particular to a paint-free ecological plywood based on poplar that can be used to make furniture such as wardrobes, cabinets, shoe cabinets, TV cabinets, bedside cabinets, bookcases, showcases, desks, etc. and its production process. Background technique [0002] At present, the adhesives commonly used in plywood production include ordinary urea-formaldehyde glue, environment-friendly urea-formaldehyde glue and isocyanate glue, etc. Common urea-formaldehyde glue produces plywood with high production efficiency and good gluing performance, but the formaldehyde emission of the product is also high, which is Production and sales are strictly prohibited by the state; the production of plywood with environmentally friendly urea-formaldehyde glue, the formaldehyde emission can reach the national standard E 2 Grade or E 1 Requirements above grade, but the production efficiency ...
