Abstract

The invention provides water-based aldehyde-free veneering glue for a wood veneer as well as a preparation method and application thereof. The glue is prepared from the following raw materials in parts by weight: 60-80 parts of vinyl acetate-ethylene copolymer emulsion, 10-20 parts of waterborne polyurethane resin, 15-25 parts of filler, 3-8 parts of environment-friendly plasticizer, 0.5-2 parts of a thickening agent, 0.1-1 part of a de-foaming agent and 3-6 parts of a curing agent. All the components of the water-based aldehyde-free veneering glue for the wood veneer provided by the invention are aldehyde-free, safe and environmentally friendly, the generation of formaldehyde is fundamentally eliminated and the glue can reach the formaldehyde-free high standard; the effectiveness of the glue can reach up to 24 hours, the opening time of the veneer is greatly prolonged and better operation time is supplied for production processing; the glue is conveniently cleaned, the production efficiency is high, the preparation components are simple and are easily acquired, the cost is low and the glue is suitable for industrial production.

Description

technical field [0001] The invention relates to the field of home decoration adhesives, in particular to a water-based formaldehyde-free veneer glue for decorative panels and its preparation method and application. Background technique [0002] In recent years, the decoration materials for interior decoration are inseparable from the use of glue. The veneer is a decorative veneer veneer plywood. It is a kind of surface material used for interior decoration or furniture manufacturing, but the veneer veneer glue that appears on the market has the following defects: 1. The formaldehyde content is high, and the free formaldehyde released from the decoration materials has a long time indoors. The release period of more than 15 years will cause serious pollution to the indoor air and cause serious harm to the human body, especially to children, the elderly and pregnant women; and the decoration will also bring serious harm to the physical and mental health of the decorators; if th...
