Embodiment 1

[0028] Example 1. Sawing straight-edged boards

[0029] 1. Milling and trimming of the edge of the base material: the sliding table saw saws the rice straw board, and the saw blade rotates at 4000r / min. Saw and cut into 250*200*32mm straight-edged boards. After milling the edge of the rice straw board, clean the edge with 180# sandpaper to remove dander.

[0030] 2. Use putty to inlay rice straw board: putty made of CaCO 3 , water, white latex, carboxymethyl cellulose, etc. (200:100:20:3), using white latex with a high solid content (50%), after the edge of the rice straw board is embedded, dry at room temperature 4h, then sand the surface with 180# sandpaper to remove the excess putty on the surface; the roughness after sanding is 4.09um.

[0031] 3. Polyurethane sealing primer: spray polyurethane sealing primer on the rice straw board, the mass ratio of polyurethane sealing primer is PU primer: PU curing agent: PU thinner = 1:0.5:0.5, viscosity 17s, spray 1 Cross (coatin...

Abstract

The invention discloses an edge coating method of a rice straw board furniture member. The method comprises the following process steps: (1) sawing a base material; (2) milling and finishing an edge of the base material; (3) inlaying putty; (4) closing a primer by polyurethane; (5) spraying a nitrocellulose primer to a rice straw board for five times; (6) spraying a nitrocellulose finish. The method has the advantages that (1) the film coating performance of the edge of rice straw board furniture is effectively improved; rational processes and paint film surface performance testing are formulated for coating of the edge of the rice straw board furniture on the basis of process practice and scientific experiments; (2) a scientific process method is provided for coating of the edge of the rice straw board furniture; (3) the utilization rate of the rice straw board in the furniture manufacturing field is favorably improved, the primer, a middle layer and the finish are matched by using the polyurethane paint and the nitrocellulose paint with higher economy and environmental friendliness, so the film coating performance of the furniture is improved, the application of the rice straw board to the furniture manufacturing field is favorably promoted, and the environment-friendly development of the furniture industry is promoted.

Description

technical field [0001] The invention relates to a finishing method for edges of rice straw board furniture, that is, the furniture made by using rice straw boards as a base material is coated on the edges. It belongs to the technical field of material and product production. Background technique [0002] Rice straw board is a board made of rice straw as raw material, with isocyanate (MDI) resin as adhesive, and through complicated processes. During use, rice straw board does not release free formaldehyde. And its density is uniform, the surface is smooth, there is no obvious color difference, and the mechanical properties meet the requirements of GB / T 4897.1~4987.7-2003 "Particleboard". Industries such as furniture manufacturing, building decoration and packaging have been applied and promoted. However, due to the roughness of the edges of rice straw boards, the edge coating quality of rice straw boards has been unsatisfactory, and its paint film adhesion and impact resist...
