Problems solved by technology

However, in the actual use of wooden floors, pavement quality problems such as arching, curling, warping, assembly gaps, and abnormal noises often occur due to moisture absorption and water absorption, which seriously affect its service life and aesthetics. high cost
Furthermore, the wood itself will have defects such as knots, insects, decay, color difference or discoloration, dry cracks, and saw wounds. If it is not treated, it will affect the surface smoothness and decorative effect of the wooden floor. Treatments such as selection, repair and bleaching will reduce the utilization rate of wood, increase the difficulty of the process and prolong the production cycle of the product
In addition, wood resources are very limited, especially wood species with good wood grain decoration effects, such as Burmese teak, big fruit red sandalwood, huanghuali and rosewood, etc. The resources are seriously scarce, the supply exceeds the demand, and the price is expensive

Abstract

The invention discloses a paper-wood composite lacquered floor and a preparation method thereof. The paper-wood composite lacquered floor comprises a water-based closed back paint layer, a paper-woodcomposite plate, an underlaying layer, a decorative pattern layer and a water-based glaze finish paint layer which are arranged sequentially from bottom to top; and the paper-wood composite plate is formed in the mode that technological wood plate blanks and pieces of kraft paper are dipped in a melamine resin adhesive, laminated alternately and subjected to hot-pressing compositing. The preparation method of the paper-wood composite lacquered floor comprises the following steps that (1) the paper-wood composite plate is prepared; (2) the two surfaces of the paper-wood composite plate are coated with the underlaying layer and the water-based closed back paint layer correspondingly; (3) the decorative pattern layer is printed on the underlaying layer; and (4) the decorative pattern layer iscoated with the water-based glaze finish paint layer. The paper-wood composite lacquered floor has the advantages that moisture-proof and waterproof performance is excellent, the decorative effect isgood, hardness is high, surface abrasion resistance is good, and safety and environmental protection are achieved; and a preparation process is simple.

Description

technical field [0001] The invention relates to a paper-wood composite lacquered floor and a preparation method thereof, belonging to the technical field of decorative materials. Background technique [0002] Wood flooring is a floor made of wood materials, mainly divided into solid wood flooring, laminate flooring, solid wood composite flooring, bamboo flooring and cork flooring. [0003] Wood flooring has natural texture and elastic feel, warm in winter and cool in summer, good stability, simple construction and good decoration, and is favored by consumers. However, in the actual use of wooden floors, pavement quality problems such as arching, curling, warping, assembly gaps, and abnormal noises often occur due to moisture absorption and water absorption, which seriously affect its service life and aesthetics. The cost is high. Furthermore, the wood itself will have defects such as knots, insects, decay, color difference or discoloration, dry cracks, and saw wounds. If i...
