Abstract

The invention relates to the technical field of wood plasticizing, in particular to a wood plasticizing agent and a preparation method thereof. The wood plasticizing agent comprises the following raw material components in percentage by mass: 20-30% of hard monomer, 5-15% of viscous soft monomer, 3-10% of acid monomer, 20-30% of tough soft monomer, and 20-40% of water. The preparation method of the wood plasticizing agent comprises the following steps: under normal temperature, the hard monomer, the viscous soft monomer, the acid monomer and the tough soft monomer are added in the water in sequence to stir for totally dissolving, and are continuously stirred by 5-10 minutes to obtain the wood plasticizing agent. All the component monomers of the plasticizing agent are colorless, tasteless, green and environment-friendly. The wood is plasticized to achieve good natural texture and to resist the damp, the corrosion and the damp-hot deformation; and the wood improves such mechanical performances as hardness, shearing resistance, bending resistance and impact resistance, is full in material source, is convenient and safe in manufacturing and use, can be widely applied to furniture manufacturing, decoration and timber construction, and is excellent in popularization and application value.

Description

technical field [0001] The invention relates to the technical field of wood plasticization, in particular to a wood plasticizer and a preparation method thereof. Background technique [0002] Since ancient times, wood has been favored by humans. Its natural texture, texture, structural mechanical properties, and ease of processing are irreplaceable by other materials, and it has been widely used in furniture manufacturing and building materials industries. However, the materials of some woods, especially plantation woods, cannot meet the needs of the public, such as their relatively loose structure, low density, easy to be eaten by insects, bacterial erosion, acid, alkali and weathering degradation, etc. In order to solve this problem, people have taken protective measures such as chemical protection, carbonization treatment, and functional improvement. The existing functional improvement technology mainly injects non-aqueous organic monomers or resins into the wood structur...
