Problems solved by technology

This case solves the technical problem that the crop straw-based inorganic composite material has poor surface flatness, and it is easy to delaminate and fall off when directly compounded with melamine-impregnated paper. However, melamine-impregnated paper will cause a certain amount of formaldehyde to be released, and the environmental protection factor is low.

Abstract

A formaldehyde-free fiber board, a preparation method thereof, and an environment-friendly processing technology for furniture. The invention discloses the formaldehyde-free fiber board and relates tothe technical field of furniture manufacturing. The fiber board is prepared from, by weight, 70-85 parts of modified bamboo carbon, 10-25 parts of a chlorophytum comosum extract, 5-10 parts of negative ion powder, 3-13 parts of a nano-photocatalyst, 1.5-3 parts of a waterborne polyurethane adhesive, 5-10 parts of ivy extract, 5-10 parts of aloe extract, 100-250 parts of distilled water, and 40-60parts of bamboo fibers. The preparation method comprises: 1) crushing and mixing; 2) hot press shaping; 3) drying. The environment-friendly processing technology for furniture by using the formaldehyde-free fiber board includes steps of: 1) material cutting; 2) edge packaging; 3) cold compression; 4) milling shaping; 5) static grinding; 6) paint coating and jointing; and 7) after-treatment. In the invention, problems that a material for manufacturing furniture is high in formaldehyde releasing quantity, has no formaldehyde adsorption function and is low in environmental protection coefficientare solved. The formaldehyde-free fiber board is prepared with the modified bamboo carbon, so that release of formaldehyde is reduced and the formaldehyde adsorption function is achieved.

Description
