Method for preparing high-density plate, printing floor and formaldehyde-absorbing floor

Abstract

The manufacturing method of a kind of high density printing floor absorbing formaldehyde comprises the following procedurals: molding high density floor -> sanding light -> covering grounding -> printing texture -> thermal pressure -> UV primer floating -> UV surface painting -> formaldehyde absorbing UV wearable surface painting -> finished product. Adding formaldehyde absorbing agent is a key for the technique. If the formaldehyde absorbing agent is too little, then the effect of absorbing formaldehyde is worse, and if the formaldehyde absorbing agent is too much, the index of the surface paint is affected. This kind of composite light-catalysis material gives good photo-catalysis properties and has good stability and good performance of repeating use in the condition of UV light, sun's rays, and the daylight lamp. In the sun's rays, the discolored ratio and the COD wiping ratio of the Rhodamine-B solution can reach to more than 95 percent in 2 hours; the decomposition ratio of phenol can reach 99.18 percent; the decomposition ratio of COD can be 95.59 percent; in the daylight lamp, the formaldehyde decomposition ratio is more than 80 percent in 24 hours. The formaldehyde content reaches GB 1 8883-2002 standard in the Room Air Quality Standard of the Country, that is the generally said E1 environment-protection standard, and it fits to generalize.

Description

technical field [0001] The invention relates to a floor manufacturing method for producing and processing high-density boards, in particular to a method for manufacturing a high-density board printed floor with printed pattern texture and a formaldehyde-absorbing floor. Background technique [0002] Solid wood composite flooring and high-density board flooring, the core layer is medium and high-density fiberboard or particleboard, and the bottom layer is balanced paper impregnated with phenolic resin, both of which contain a large amount of formaldehyde. Formaldehyde has a melting point of -92°C, a boiling point of -21°C, and a liquid density of 0.815 g / m 3 cm (20°C), easily soluble in water and ethanol. Formaldehyde molecule has aldehyde group, which is an important organic raw material, and is a colorless, irritating gas with a strong smell. Formaldehyde can be contained in various artificial boards (particle board, fiberboard, plywood, etc.) due to the use of adhesives....

Problems solved by technology

Due to the limitations of technology and materials, the use of raw materials containing formaldehyde components cannot be completely banned in the process of manufacturing indoor furniture and decoration, and the hazards of formaldehyde cannot be removed from the source. Therefore, efficient and environmentally friendly indoor formaldehyde removal materials have good potential. application prospects
