Embodiment Construction

[0020] The present invention first prepares raw materials and configures photocatalytic dilution solution, then refits traditional felting equipment, sprays photocatalytic dilution solution on the cotton net during the felting process, and uses ultraviolet light to illuminate at the same time, so that formaldehyde process is eliminated. The specific process is as follows:

[0021] see figure 1 , Considering the sound absorption and cost of the cotton felt, the present invention selects regenerated fine-denier long-staple cotton and 110°C low-melting fiber as raw materials in the present invention, and the 110°C low-melting fiber selects fiber with a sheath-core structure. The weight ratio of regenerated fine-denier long-staple cotton to 110°C low-melting fiber is 3:1.

[0022] When selecting raw materials, configure photocatalyst dilution solution: first select titanium concentrate with high titanium dioxide content as raw material, add molten ore agent, after firing and aci...

Abstract

The invention discloses a preparation method of a photocatalyst formaldehyde-removal blanket. Regenerated fine-denier long-stapled cotton and low-melting-point fiber with the temperature of 110 DEG C are selected as the raw materials, and meanwhile a photocatalyst dilute solution is prepared; regenerated fine-denier long-stapled cotton and low-melting-point fiber with the temperature of 110 DEG C are put into an opener to be opened and enter a carding machine to be carded after being mixed by a mixer, and a web is output; a high-pressure spraying gun is started to continuously and evenly spray the photocatalyst dilute solution to the upper surface of the web when the web is output by the carding machine to enter a web laying machine; when the web loaded with the photocatalyst dilute solution sequentially enters the web laying machine, a high-temperature oven, a low-temperature oven, an ironing roller and a cooling machine, an ultraviolet lamp is always turned on to irradiate nanometer titanium dioxide. A felt is rapidly and sufficiently loaded with the photocatalyst dilute solution through a spraying process, and the photocatalyst dilute solution has an efficient catalytic effect on removing formaldehyde through the ultraviolet lamp.

Description

technical field [0001] The invention relates to a preparation technology of interior decoration materials, in particular to a method for making cotton felt used in indoors, cars and other places. Background technique [0002] Cotton felts used in rooms and cars are generally polluted by formaldehyde. Formaldehyde is a highly toxic substance with teratogenic and carcinogenic effects. Traditional methods to eliminate formaldehyde include: ventilation method, activated carbon adsorption method and chemical method. Ventilation method and activated carbon adsorption method are environmentally friendly and healthy to remove formaldehyde, but time-consuming and incomplete removal; chemical method to remove formaldehyde saves time and effort, but is not environmentally friendly. For example, chemical air treatment products are obtained through artificial synthesis, many of which are aromatic. Almost all aromatic compounds contain benzene ring compounds that have been proven or susp...
