Embodiment 1

[0013] The method of manufacturing decorative plywood with self-cleaning and breathing functions, the process is specifically divided into:

[0014] a. Grind the conventional pyrolysis process bamboo charcoal with a carbonization temperature of about 700°C to 200-300 mesh powdery carbon, take nano-scale titanium dioxide powder accounting for 3% of the powdery carbon weight, mix the two and stir with boiling water to make a mixture For emulsion, the ratio of solid to boiling water is 1:5-10, and the stirring time is 60 minutes;

[0015] b. The mixed emulsion placed in the container is dried to a moisture content of 10% at a temperature of about 100°C, taken out and rolled into powder;

[0016] c. Drill the poplar or pine plywood with the paint film on the surface or the veneer of the decorative paper with a punching machine, and the hole is in the form of a counterbore. Number of holes 200~800 / m 2 , take a small value for a large number of apertures, and a large value for a s...

Abstract

The invention discloses a method for manufacturing respiration type artificial board capable of absorbing and decomposing organic matter, comprising the following process steps of: 1. taking bamboo slack coal as an intermediate carrier, and enabling nanometer titanium dioxide to be loaded on the intermediate carrier to prepare titanium dioxide modified bamboo slack coal; 2. punching counter bores on the surface of a decorative artificial board (comprising a glued board, a medium density fiberboard and a shaving board), wherein the number of the bores is 200-800/m2; 3. coating normal-temperature curing type adhesives to the bottoms and the inner walls of the counter bores; 4. evenly spreading the modified bamboo slack coal in the counter bores; and 5. laying the artificial board with the counter bores until the adhesives are solidified. The invention has the advantages that the respiration type artificial board can absorb the organic matter doing harm to human bodies under the action of light and decomposes the organic matter into carbon dioxide and water. The artificial board is a long-acting environment-friendly material used for public places having requirements for sound absorption and heat insulation.

Description

technical field [0001] The invention relates to a manufacturing method of a breathing artificial board capable of absorbing and decomposing organic matter, and belongs to the technical field of wood processing. Background technique [0002] With the improvement of people's awareness of environmental protection, higher requirements have been put forward for the widely used wood-based panels for interior decoration. At present, various wood-based panels (plywood, fiberboard, particle board) are formed by hot-pressing and gluing wood unit materials with adhesives. Adhesives are indispensable basic materials in the production of wood-based panels. At present, almost all wood-based panels consider the production cost and the performance of the adhesive. The adhesives used all contain formaldehyde. The wood-based panels produced release formaldehyde and other harmful organic substances to varying degrees during use. (Gas), and the release process of these organic substances in th...
