Problems solved by technology

However, bamboo charcoal is brittle, and it is difficult to directly make boards for building use, which greatly limits its application in building decoration.
Other carbon materials such as charcoal, fruit shell charcoal, crop straw charcoal, coal-based charcoal, etc. also have the problem of brittleness.

Embodiment 1

[0017] Based on weight, granular bamboo charcoal (in dry basis): granular tourmaline (in dry basis): polyvinyl acetate emulsion (in terms of solid content 100%) is 77: 5: 15 ingredients, bamboo charcoal particle diameter It is 25 μm to 800 μm, and the particle size of tourmaline is 10 μm to 1 mm. Mix the adhesive diluted to a solid content of 50% with granular bamboo charcoal and granular tourmaline, and evenly coat the mixture of glue, granular bamboo charcoal, and granular tourmaline on one surface of the veneer material 1 , cover the veneer material 1 on the other side of the mixture of glue and granular bamboo charcoal required by a certain thickness. Roll the mixture of glue, granular bamboo charcoal, and granular tourmaline sandwiched by the veneer material 1 together with the veneer material 1 into a plate shape, and dry it with hot air at 50-120°C in a drying oven for 2- After 10 minutes, a carbon plate is formed.

Embodiment 2

[0019] Based on weight, according to granular bamboo charcoal (in dry basis): polyvinyl acetate emulsion (in terms of solid content 100%): decabromodiphenylethane is 82: 15: 1.5 ingredients, and the particle size of bamboo charcoal is 25 μm~ 800 μm. The adhesive that is diluted to 50% solid content is mixed with decabromodiphenylethane and granular bamboo charcoal, and the mixture of glue after mixing and decabromodiphenylethane and granular bamboo charcoal is coated according to the method described in Example 1. Cloth, rolling and drying methods are formed and dried into carbon plates.

Embodiment 3

[0021] Based on weight, granular bamboo charcoal (in dry basis): polyvinyl acetate emulsion (in terms of solid content 100%): polystyrene-acrylic acid ester emulsion (in terms of solid content 100%): glyceryl triacetate The ingredients are 82:7.5:7.5:0.7, and the particle size of bamboo charcoal is 25 μm to 800 μm. Be diluted to the solid content of 50% mixed adhesive and triacetin, granular bamboo charcoal mix uniformly, the mixture of glue after mixing and triacetin, granular bamboo charcoal is by the coating described in embodiment 1, roll pressing and The drying method is to form and dry into a carbon plate.

Abstract

The present invention relates to a carbon plate and its preparation method, belonging to the field of indoor decorative material. Said carbon plate is composed of veneer material and intermediate mixture sandwich. Said intermediate mixture sandwich composition includes (by dry base weight portion) 100 portions of granular carbon and 5-33 portions of adhesive. Said carbon plate has the functions of adsorbing and purifying gas, regulating moisture and radiating far-infrared ray, and contains no the components of formaldehyde, toluene and dimethylbenzene, etc.

Description

technical field [0001] The invention relates to a carbon plate for interior decoration and furniture inner lining material with charcoal and adhesive as main components and a manufacturing method thereof. technical background [0002] Bamboo is a rapidly renewable resource. Bamboo has a special microporous structure. Bamboo charcoal produced by pyrolysis and carbonization of bamboo is a porous material with a large specific surface area and strong adsorption capacity. It has good purification Air, water purification, adsorption of harmful gases, humidity adjustment, electromagnetic shielding, far-infrared radiation, UV protection and other functions, bamboo charcoal also has the characteristics of fire and heat resistance, good chemical stability, light weight, etc., and has a wide range of uses. If it is used as building and decoration material, it can purify the air and adjust the humidity. It can keep the house comfortable and pleasant, and make people feel stable, which ...
